In recent years, people have paid more attention to the comfort, health and safety of clothing fabrics. Requirements for safety and environmental protection are getting higher and higher. As people spend more time outdoors, the trend of mutual penetration and integration of casual wear and sportswear is increasingly favored by consumers. At the same time, workwear for people engaged in manual labor also puts forward comfort requirements for fabrics. The fabric of this type of clothing requires that the clothing will not stick to the skin and cause a cold and wet feeling when sweating occurs during activities. Therefore, new requirements for moisture absorption and sweat wicking functions have been put forward for fabrics.
As we all know, natural fibers such as cotton have good hygroscopic properties and are comfortable to wear, but have poor wrinkle resistance, shape retention and water conductivity. When people sweat a little more, cotton fibers will expand due to moisture absorption, and their performance will decrease and stains. attached to the skin, at the same time, the water dispersion speed is also slow, thus giving the human body It creates a cold and wet feeling. Due to the lack of hydrophilic groups, synthetic fibers represented by polyester have poor hygroscopicity. During people’s use, the moisture emitted by the human body is difficult to pass through the polyester fabric and is easily absorbed. Produces a feeling of stuffy heat and discomfort
Moisture-absorbing and sweat-wicking fibers have a high specific surface area. There are many micropores or fibril gaps and surface grooves on the fiber surface that communicate between the inside and outside, making it easy for moisture to enter between the fibers. At the same time, there are many tubular grooves along the fiber axis. Or capillaries, which provide channels for the migration of water, so the fiber has good water absorption and does not swell due to water absorption after absorbing water. The moisture between fibers is mainly held by the fibers by the attraction of a large number of microporous capillaries, or mechanically maintained in the capillaries between fibers. Under normal ambient temperature, the moisture is easily transported to the surface of the fibers and evaporates.
Judging from the current industrialization of moisture-wicking polyester, physical methods are mainly used to spin several types of heterosexual fibers such as cross-shaped, Y-shaped, T-shaped and honeycomb fibers. There are varying numbers of micro-grooves on their surfaces. With the help of the grooves, Wicking moisture-conducting structure for quick absorption Moisture and sweat on the surface of the skin are instantly expelled from the body, and then the fibers on the surface of the cloth diffuse the sweat and quickly evaporate it, thereby achieving the purpose of moisture absorption, sweating, and regulating body temperature, keeping the skin dry and cool.
At present, major well-known clothing brand companies at home and abroad have made significant progress in the research and development of moisture-wicking fiber products, including fiber, dyeing, weaving, finishing and garments. The production technology is increasingly improved, and the performance of the products and stable quality, has formed a A certain size of the market. Fabrics made of moisture-wicking fibers are widely used in sportswear, outdoor travel and leisure wear, because of their excellent properties such as light weight, moisture conduction, quick drying, coolness, comfort, easy cleaning, and no ironing. Underwear, shirts and other fields are favored by consumers. It can achieve the effect of moisture absorption and quick drying without adding any additives. It is an emerging environmentally friendly fabric that is durable, green, and safe. It is used in the market from woven to knitted, from fiber to yarn, and from fabric to clothing and home textiles. , moisture-absorbing and sweat-wicking fiber products can be seen. A complete moisture-wicking fiber industry chain has been formed. In the future, moisture-wicking products will develop into multi-purpose products, such as workwear, military supplies, medical, footwear, etc., with broad application space and unlimited future market development potential.
At present, the moisture-absorbing and sweat-wicking fibers that are widely used and effective include: Coolmax fiber of DuPont in the United States, Topcool fiber of Taiwan’s Far East Textile, Coolpus fiber of Taiwan’s Zhongxing Textile, etc. Common specifications of moisture-wicking fiber include filament, short fiber, and short fiber. The fibers are mostly blended with cotton, linen, tencel and other raw materials
Our company began to research moisture-wicking fabrics a few years ago, and combined with anti-static and other functions, it is mainly used for workwear and military products. After testing by national authoritative institutions, our products have reached GB/T 21655.1 -National standard stipulated in the 2008 “Evaluation of Moisture Absorption and Quick Drying Properties of Textiles”
