Single Jersey Fabric & Double-Sided Fabric 1. What Is Single Jersey? Single Jersey Fabric is a type of circular knitted fabric (Weft Knit). The knitting machine for single jersey fabric has only one row of needles, while the knitting machine for double jersey fabric has two rows of needles. This makes the fabric feel like it has only one layer when woven (much like basic knitting yarn), and the textures on both sides are different, which is why it is called “single jersey fabric”. Characteristics of single-sided fabric If you have single-sided fabric in your hand, you can feel the feel of both sides. Usually, the feel of both sides will be slightly different. Single-sided fabric feels softer, lighter, and has more drape than double-sided fabric (if they are of the same specifications). Single-sided fabric is also more breathable than double-sided fabric. Uses of single-sided fabric Single-sided fabric can usually be used as T-shirts, sports tops, yoga pants, etc. Because single-sided fabric is more breathable than double-sided fabric, sweat is easier to discharge from the skin. 2. Double-Sided Fabric Interlock or double knit is also a type of circular knit fabric (Weft Knit). The interlock knitting machine has two rows of needles, and the fabric is like weaving the backs of two single-sided fabrics together. There are many types of interlock fabrics, such as rib fabric, PK fabric, health fabric, etc. But if it is a flat double-sided fabric, the weave on both sides of the fabric will be the same, so it is called “interlock fabric”. Characteristics of double-sided fabric Compared with single-sided fabric, double-sided fabric is usually thicker, heavier, and stiffer (if it is of the same specifications), but it is less breathable than single-sided fabric. Uses of double-sided fabric Double-sided fabric can be used as trousers, skirts, opaque sports tights, polo shirts, etc. It has a wide range of uses, and the clothes made are usually stiffer. 3. How To Distinguish Single-Sided Fabric From Double-Sided Fabric? If you look closely at the weave of a plain single-sided fabric, you will find that the weave on both sides is different. On the contrary, the two sides of a double-sided fabric look the same. However, the above method can only be used for plain single-sided and double-sided fabrics. If it is a woven fabric, please use the second method: stretch the fabric to observe the curling of the fabric edge. Put your fabric straight (the weave is perpendicular to you), then pull the left and right edges of the fabric to see if the fabric edge parallel to you curls. If there is curling, it is a single-sided fabric, and if there is no curling, it is a double-sided fabric. This is why double-sided fabric is often used for laser cutting or seamless cutting of underwear.

How to Check Fabric Composition 1. Unlocking the Importance of Fabric Fiber Composition A fabric’s fiber composition refers to the weight percentage of each fiber that makes up the fabric.When you have a fabric swatch with an unknown fiber composition, it becomes extremely challenging to reorder the same fabric. Where would you even begin with a Google search? After reading this article, you won’t need to rely on your fabric supplier to determine the fiber composition for you. Here’s what you’ll learn: Why is a fabric’s fiber composition so important? How to check the fiber composition of knitted fabrics? 2. Why is a fabric’s fiber composition so important? 1. When Sourcing Fabric: The fiber composition is the first detail you should know when sourcing fabric. Providing this information to your fabric supplier ensures they can match your requirements accurately. 2. When Verifying Ordered Fabrics: Ensuring the fiber content matches expectations is essential for transparency and customer satisfaction. It ensures customers receive what they pay for. 3. For Labeling Compliance: Fiber content impacts import/export tariffs and regulatory compliance. Most countries require accurate fiber content labels on finished products. 3. How to check the fiber composition of fabrics？ Tools Needed: – Scissors – Precision digital scale – Pen – Paper for notes Steps to Check Fiber Composition: 1. Sampling:Cut a small piece (approximately 3-4 cm) from the fabric swatch for testing. Minimize waste, especially with expensive fabrics. 2. Yarn Extraction:Orient the fabric vertically to identify the pattern. Start pulling yarn from the edge until you extract a full strand across the fabric. This process requires patience. 3. Sorting Yarns:Separate visually or tactically different yarns into distinct piles. Note the sequence of extraction to gather at least 10 strands of each type for accuracy. 4. Weighing:Use a scale to weigh each pile of sorted yarns and record their weights. 5.

What Is Color Fastness 1. About Color Fastness. Color fastness refers to the resistance of a fabric’s color to fading or running. It measures how well a fabric retains its color when subjected to various conditions such as washing, exposure to sunlight, rubbing, perspiration, and environmental factors. High color fastness means the fabric maintains its original color for a long time, while low color fastness means the color fades or bleeds easily. 2. Is the Color Fastness of Fabrics Very Important? It is very important to know the color fastness of your fabric. First, the design of the clothes may have different colors of fabrics stitching, such as white and black, which are contrasting colors. We need to ensure that the light colors will not be stained by dark colors after washing. Second, knowing the color fastness can correctly mark the care instructions on the label, such as washing temperature, washing with clothes of the same color, etc. Third, ensure quality. If the clothes are complained by customers or even accumulated negative reviews due to color fastness issues after they are made, it will affect the reputation of the brand or company. 3. Common Color Fastness Test Standards. Color Fastness to Washing: ISO 105 C06 and AATCC61 are the most common color fastness test standards for measuring fabrics after home washing. The fabric will be washed with six-fiber strips in a special washing color fastness machine at a specific temperature, and then taken out and dried to determine the degree of fading and transfer to the six-fiber strips.Each test standard has specified washing temperature, water volume, amount of detergent or agent, and washing time. In addition, some test standards will also add small steel balls to simulate the fading caused by friction between fabrics and other clothing or accessories in the washing machine. For example, AATCC61-2A is a very common washing simulation test. Its 45-minute test with steel balls is intended to simulate the results after five home washes. Generally, if the fabric can pass the self-color change (fading) level 4 and the transfer dyeing to the six-fiber strands level 4, it is of very good quality. However, sometimes there will be differences in color depth and brightness, and not all colors can reach such a level. Color Fastness to Water: ISO 105 E01 and AATCC 107 are the most common water fastness test standards used to determine whether the color of fabrics will change or transfer due to immersion in water during the washing process. Color Fastness to Light: ISO 105 B02 and AATCC 16 Option 3 are the most common test standards for color fastness to sunlight, which are used to test the color fastness of fabrics exposed to sunlight or fluorescent lights. The test fabrics will be placed in a machine that simulates sunlight. The AATCC 16 Option 3 test method is to place the fabric in a fading instrument and irradiate it with high-intensity ultraviolet light with a wavelength similar to that of sunlight for 40 hours to measure the degree of fading. Such tests are particularly important for outdoor clothing, or to test whether daily wear can fade after being exposed to sunlight. Color Fastness to Crocking (Rubbing) : AATCC 8 and ISO 105 X12 are the most common rubbing color fastness test standards, which are used to test the degree of transfer of dyes to other fabrics after fabrics are rubbed. For example, if we put on a dark coat over a white T-shirt, the fabrics may transfer dyes due to mutual friction all day long. The rubbing color fastness will test the transfer of dyes by rubbing dry fabrics and wet fabrics – the test fabric will be rubbed back and forth with a fixed force and frequency on a non-dyed fabric in a dry or wet state using a special machine for testing friction. Finally, the degree of transfer of dyes to the non-dyed fabric is observed. If it can reach level 4 for dry friction and level 3-3.5 for wet friction, the quality is very good. Color Fastness to Sweat: ISO 105 E04 and AATCC 15 are the most common perspiration fastness test standards, and are often used on sports fabrics. The test uses a six-fiber strip to test whether the color of the fabric will transfer to other fabrics through wet sweat. AATCC 15 tests acid perspiration color fastness, while ISO 105 E04 tests acid and alkaline perspiration color fastness. Human sweat is usually acidic, but it can become alkaline at high temperatures or due to bacteria. Other Common Fastness Test: chlorine water fastness test and seawater fastness test. 4. How to Improve Color Fastness? Sometimes dyeing factories will find that the color fastness required by the brand is not good, so they will use fixing agents in the process to ensure color fastness. But the fixing agent cannot make the color fastness reach level 5. The color of the fabric itself is a very important factor. For example, the color fastness of light colors in sunlight is worse than that of dark colors. The color fastness of neon colors, brighter colors, and darker colors is generally poor, and it is also more prone to color staining. If the fabric itself is ordinary polyester fiber (Polyester), it can also be replaced by CD yarn (Cationic Polyester) to improve the color fastness of washing. However, it should be noted that switching to CD yarn still cannot improve the color fastness in sunlight, and the cost will increase as a result. Brands sometimes have to compromise on the choice of color or design in order to achieve the required color fastness.

What Is Fabric Shrinkage 1. About The Fabric Shrinkage Fabric shrinkage refers to the reduction in size of a fabric or garment after it is subjected to certain conditions, such as washing, drying, or exposure to heat and moisture. This phenomenon occurs due to the relaxation of tensions applied to the fibers during the manufacturing process. 2. Why We Need to Test The Shrinkage of Fabrics? First, manufacturers need to do shrinkage tests to control the quality of fabrics or clothes, and brands also need to maintain their reputation. Moreover, if the quality is poor, it needs to be remade, which will cause waste of resources and raw materials. Second, if the shrinkage problem of fabrics is not discovered until after the clothes are made, they may become skewed or shrunk after washing. Wrinkles may appear at the seams. The appearance of clothes may also be affected when they are hung or folded. Finally, manufacturers must print correct care labels on clothes to inform consumers how to properly care for clothes. If the shrinkage rate is not tested and the incorrect care label is printed, consumers may damage the clothes by washing them incorrectly. 3. Factors Influencing Fabric Shrinkage Fiber Content: Natural fibers like cotton, wool, and linen are more prone to shrinkage compared to synthetic fibers like polyester and nylon. Blended fabrics may exhibit different shrinkage behaviors depending on the proportion of each fiber type. Yarn and Fabric Construction: The way yarns are spun and fabrics are woven or knitted can affect shrinkage. Tightly woven or knitted fabrics tend to shrink less than loosely constructed ones. Finishing Processes: Pre-shrinking treatments (e.g., Sanforization) during manufacturing can reduce shrinkage. Other finishing processes like mercerization or heat setting can also stabilize the fabric dimensions. Washing and Drying Conditions: High temperatures and mechanical agitation during washing and drying can increase shrinkage. Using hot water, high heat drying, and vigorous agitation are common causes of shrinkage. 4. How to Prevent Fabric From Shrinking? There are several ways to prevent fabric from shrinking after washing, but they are usually used on cotton fabrics that shrink more. Common treatments include mercerization or shrink-proofing. Artificial fibers, such as nylon, shrink when exposed to high temperatures, but the shrinkage can be controlled during shaping. However, it is not reasonable to set a completely 0% shrinkage standard. No matter what ingredients are used or what process is used, fabrics usually shrink a little, so an acceptable range should be set. And this range value usually depends on the composition and organization of the fabric.

What Are Polyester and Nylon Fabrics and Their Differences ? 1. Introduction Polyester and nylon have a lot in common. They are both lightweight man-made fibers and are very popular for sportswear. Because they are more durable than natural fibers, they are also more likely to be enhanced by adding functional additives. 2. Where Do Polyester Fiber and Nylon Fiber Come From? Nylon (also known as Polyamide in Europe) was invented in 1935 and became famous after being made into stockings. Polyester also became more and more widely used in the 1940s. Both nylon and polyester are plastic compounds extracted from petroleum. At first, they were used to create stronger, lighter and more durable materials, and later gradually replaced natural fiber fabrics. But how are polyester and nylon fibers made? The manufacturing process of the two fibers is very similar. The manufacturer melts the plastic pellets (about the size of rice grains), passes them through a special solvent, and then shoots out yarn through a nozzle. The yarn will be made into different thicknesses or specifications according to different uses. 3. What Is the Difference Between Polyester and Nylon? Feel and Performance: Nylon was invented to develop an alternative to silk, so it also has soft and smooth properties. Nylon is also shinier and more elastic than polyester. In comparison, polyester is thicker and less shiny. But as technology has improved, the feel of polyester has become better and better. Now, you can find polyester that feels like cotton, or polyester that feels similar to nylon. Dyeing: Polyester fibers are dyed with disperse dyes, while nylon fibers are dyed with acid dyes. There is another modified material of polyester fibers, called cationic-dyeable polyester (or CD Polyester for short). This fiber uses salt-based dyes and has a higher color brightness. Nylon is dyed with acid dyes. It is a more difficult material in the industry because the terminal amino acids of nylon are unevenly distributed, resulting in different absorption of acid dyes. Because nylon is more sensitive, it may cause horizontal stripes during the fiber processing and weaving process. Therefore, the spinning, weaving and dyeing of nylon are very demanding on the manufacturer’s technology. Since nylon and polyester fibers need to be colored with different dyes, many yarn mills use this property to twist the two types of yarn together to create a double-color or twist effect after dyeing. If acid dyes are used, nylon fibers will absorb the dye, but polyester fibers will not, thus creating a twist effect. Or if disperse dyes are used, nylon will still be colored, but not as much as polyester fibers, and the twist effect is less obvious. Or double dyeing can be used to create a double-color effect. Durability: Both nylon and polyester are considered strong and durable fibers. However, if you compare the two, nylon is stronger and more ductile than polyester, which means that products made of nylon are more durable than polyester! Nevertheless, when nylon is rubbed, it is more likely to pilling than polyester. Although this does not reduce its strength, it will make the appearance have traces of use. Reaction to Water: Nylon has a high water content, and when it comes into contact with water, it can stretch 3.5% more. So when we sweat or exercise in the rain while wearing nylon clothes, nylon will take a longer time to dry. In contrast, polyester fibers do not absorb water and are hydrophobic. So if the fabric has the effect of wicking moisture, sweat will be absorbed into the fiber and evaporate more quickly. Therefore, polyester fibers are very suitable for sportswear fabrics for high-intensity sports. Reaction to Heat： Next, how do nylon and polyester react to heat? Polyester is the more heat-resistant option, as it requires high temperatures to absorb dye. Therefore, polyester fabrics are also popular choices for sublimation transfer and digital printing. Nylon, on the other hand, cannot withstand high temperatures, so it cannot be used for heat transfer and digital printing, which require high-temperature printing. Cleaning and Maintenance： Both fabrics are easy to clean. They will not wrinkle, become long or short. However, please do not dry clean nylon or polyester fabrics, or iron or tumble dry them at high temperatures. If it is nylon or polyester sportswear, which has the effect of wicking sweat, you should avoid adding fabric softener to the washing. 4. Which Fiber Is Better? Nylon and polyester both have their own characteristics. Which material is more suitable for your product should depend on the design and application of the product itself. The soft feel of nylon is difficult to replace, which is why many yoga or underwear brands prefer to use nylon fabrics. But although nylon is softer and tougher, polyester fiber dries faster, is easier to color, and has better color fastness. Because of this, polyester fiber is more likely to be used in some high-strength sportswear, such as: running, basketball, football, rugby, etc. Although they each have their own characteristics, as technology becomes more and more advanced, the shortcomings of the two materials are gradually being improved. For example, polyester fibers are becoming softer and softer, and nylon can also absorb moisture and perspiration quickly by adding moisture-absorbing and perspiration-wicking agents.

Easy Methods to Tell Apart Knit and Woven Fabrics 1. How can we tell apart knit and woven fabric? When it comes to fabrics, distinguishing between knits and woven materials may seem challenging at first glance. However, with a few simple methods, you can easily identify whether a fabric is knit or woven. A. Visual Examination Fabrics are named according to the method used to create them, which is visible upon close inspection. Woven Fabrics: These are crafted by interlacing yarns in a criss-cross pattern, akin to traditional weaving techniques used for centuries. Imagine the intricate overlap seen in screen doors or tennis racket nets, but tightly woven to form a solid fabric. Knit Fabrics: Knits are categorized into weft knits and warp knits. Weft knits, like hand-knitted sweaters, feature a distinctive V-shaped pattern in their weave. In contrast, warp knits display a more complex pattern, often resembling stripes. B. Thread Pulling Test To further differentiate between knit and woven fabrics, try pulling at the threads along the fabric’s edge. Woven Fabrics: Threads in woven fabrics are easily pulled out from the edges due to their straightforward interlacing. This characteristic makes woven fabrics unravel relatively easily. Knit fabrics differ in thread pullability: weft knits allow thread pulling, albeit more difficult due to interwoven nature, while warp knits securely anchor threads, making hand pulling nearly impossible. C. Elasticity Test Elasticity is another key factor that distinguishes knit from woven fabrics. Woven Fabrics: Typically, woven fabrics have minimal elasticity. The tightly packed criss-cross pattern restricts stretchiness. Knit fabrics vary in elasticity: weft knits stretch noticeably due to interwoven threads, while warp knits’ elasticity hinges on the inclusion of elastic fibers, otherwise resembling woven fabrics in stretchability. 2. Summary These simple methods—visual examination, thread pulling, and elasticity testing—provide practical ways to identify knit and woven fabrics accurately. Whether you’re a consumer or designer, understanding these distinctions enhances your ability to choose fabrics suited to your needs. By mastering these techniques, you’ll confidently navigate the world of fabrics, appreciating their diverse characteristics and applications.

Unveiling the Science of Cooling Fabrics: Enhancing Comfort Through Innovative Design 1. The Theory Behind Cool When we talk about “cool” fabrics, it’s easy to jump to the conclusion that these textiles act like portable air conditioners, constantly keeping us chilled. However, the reality is far more nuanced. Coolness in fabrics isn’t just about immediate sensations (contact cooling); it involves a complex interplay of factors that enhance comfort and manage temperature effectively. Feeling cool isn’t just about perception; it’s a physiological response where our body temperature decreases. But how does fabric influence this process? The human body dissipates heat through several mechanisms: radiation, convection, conduction, and evaporation. Thermal conductivity: Different materials conduct heat differently. Fabrics with high thermal conductivity can impart a cooling sensation, whereas those with low conductivity may feel warmer. Thermal convection: This refers to the transfer of heat from one place to another via fluid movement. For instance, when you wear a feather jacket, initially, it feels cool because your body’s heat transfers to the cooler fabric. Cooling through evaporation: Sweat evaporation plays a crucial role in heat dissipation. Fabrics that allow moisture to evaporate quickly help in keeping the body cool and dry. Blocking heat sources is one of the simplest ways to stay cool. Clothing acts as a barrier against direct solar radiation, which helps in maintaining lower body temperatures. Research indicates that wearing regular clothing in the sun can lower body temperature compared to being exposed directly to sunlight. Schoeller’s Coldblack technology exemplifies this principle by reflecting sunlight, thereby preventing body heat accumulation. Understanding these principles helps in designing fabrics that optimize cooling through radiation, convection, conduction, and evaporation mechanisms. 2. Which Material Offers the Best Cooling Properties? The effectiveness of a fabric’s cooling properties depends on its ability to manage these heat dissipation mechanisms. Here are some materials known for their cooling effects: Polyester: Known for its low moisture absorption (0.4%), polyester dries quickly, providing a refreshing feel. Fabrics like Coolmax use specially designed yarns with enhanced moisture-wicking properties, promoting faster sweat evaporation and reducing stuffiness. Nylon: With a higher moisture regain (4%) compared to polyester, nylon has better heat conductivity. While it dries slower than polyester, lightweight nylon fabrics still offer contact cooling sensations indoors. Rayon: A semi-synthetic fiber made from wood pulp, rayon can be adjusted for varying moisture regain properties, offering a soft touch and cooling capabilities. 3.Materials That Enhance the Cooling Effect Innovative materials like jade, graphene, and xylitol further enhance fabric cooling: Jade: Known for its natural cooling properties due to its excellent thermal conductivity, jade-infused fabrics quickly conduct heat away from the body, ideal for indoor environments. Graphene: Despite its reputation for warmth, graphene’s exceptional conductivity can dissipate body heat when incorporated into thin, breathable fabrics, balancing body temperature with the environment. Xylitol: This material absorbs heat upon contact with moisture (sweat), providing a cooling sensation similar to the effect of xylitol in chewing gum. It can be applied directly to fabrics or added to yarns to enhance cooling properties. Texture plays a critical role in a fabric’s cooling performance. Lighter, less dense weaves or meshes facilitate quicker drying and enhance evaporation, promoting faster cooling through moisture management. Innovative approaches like body mapping designs and moisture-responsive transformation fibers further optimize cooling by targeting high-sweat areas and improving heat convection.Cooling fabrics offer diverse pathways to achieve comfort and temperature regulation. By understanding the science behind these materials—thermal conductivity, moisture management, and innovative enhancements like jade and graphene—designers and consumers can make informed choices. Whether for everyday wear or high-performance activewear, choosing fabrics that optimize heat dissipation mechanisms ensures comfort and enhances overall well-being.

What is Waterproof and Breathable Technical Fabric ? 1.What is Waterproof and Breathable Technical Fabric? Waterproof and breathable (WPB) fabrics are specialized materials designed to repel water from the outside while allowing moisture vapor to escape from the inside. This dual functionality is essential for maintaining comfort and dryness, particularly in outdoor environments. 2. Key Components: 1. Outer Layer (Face Fabric): – Typically made from nylon or polyester. – Treated with Durable Water Repellent (DWR) to make water bead up and roll off. 2. Membrane or Coating: – Positioned beneath the outer layer. – Composed of materials like ePTFE (expanded polytetrafluoroethylene) or PU (polyurethane). – The membrane has microscopic pores large enough for water vapor to escape but small enough to block liquid water. 3. Inner Layer (Lining): – Protects the membrane and enhances comfort. – Often made from tricot or mesh, which adds breathability and moisture-wicking properties. 3. How Waterproof and Breathable Fabrics Work The WPB fabric functions through a combination of hydrophobic and microporous properties. The outer DWR treatment repels water, while the membrane’s micro-pores allow perspiration in the form of water vapor to pass through. This technology ensures that while external water is kept out, internal moisture is efficiently managed, preventing the wearer from feeling clammy or wet from sweat. 4. Why Use Waterproof and Breathable Fabric for Outdoor Jackets? 1. Protection from the Elements: – Waterproofing: Keeps rain, snow, and moisture out, ensuring the wearer stays dry in wet conditions. – Windproofing: Many WPB fabrics also provide wind resistance, adding an extra layer of protection against cold and blustery weather. 2. Comfort and Breathability: – Moisture Management: By allowing sweat to escape, WPB fabrics prevent overheating and excessive sweating, maintaining a comfortable microclimate inside the jacket. – Temperature Regulation: Breathable fabrics help in regulating body temperature by allowing excess heat to dissipate. 3. Versatility and Durability: – Multi-Season Use: Suitable for a variety of weather conditions, making them ideal for activities such as hiking, skiing, mountaineering, and other outdoor sports. – Durable: Designed to withstand rugged outdoor use, these fabrics are often abrasion-resistant and long-lasting. 4. Enhanced Performance: – Lightweight: Modern WPB fabrics are designed to be lightweight, ensuring that the jacket does not become a burden during extended wear. – Flexibility: Provides ease of movement, crucial for active pursuits where mobility is essential. 5. Popular Technologies and Brands Several brands have developed their own WPB technologies, each with unique features: – Gore-Tex: Known for its robust waterproofing and breathability, Gore-Tex is one of the most recognized WPB fabrics. – eVent: Offers excellent breathability with Direct Venting technology, which allows air to flow directly through the fabric. – Polartec NeoShell: Combines breathability and waterproofing with a soft, flexible feel. – H2No by Patagonia: Provides a durable and highly waterproof option with an emphasis on environmental sustainability. 6. Conclusion Waterproof and breathable fabrics represent a significant advancement in outdoor apparel technology, combining the essential elements of protection, comfort, and performance. For anyone looking to explore the great outdoors, whether through hiking, skiing, or simply navigating a rainy city, an outdoor jacket made from WPB fabric is an indispensable piece of gear. With the right WPB jacket, adventurers can confidently face the elements while staying dry, comfortable, and ready for whatever nature throws their way.
