With the development of competitive sports and the popularization of mass fitness, modern sportswear continues to progress and innovate in fabrics, styles and colors. From the point of view of fabric development, from natural fiber fabrics to chemical fiber fabrics to hybrid fiber fabrics, scientists continue to develop materials that provide maximum comfort, minimal fatigue, and weight to the human body. In order to maximize human comfort, scientists have recently developed a variety of highly hygroscopic fibers. High absorption and desorption polyurethane fibers: Due to its good elasticity, polyurethane fibers are widely used in sportswear such as gymnastics, aerobics, techniques, swimming, and track and field. With the continuous improvement of the comfort requirements of professional athletes for clothing, the technical development of polyurethane fibers has expanded from simple stretching functions to the development of highly functional fibers that are compatible with the use. Japan's Asahi Kasei Corporation's first high moisture absorption and desorption polyurethane fiber, characterized by a large amount of moisture absorption, and the speed of rapid release, can quickly release steam and sweat to maintain comfort. Its moisture absorption performance is almost the same as that of cotton. The moisture release performance of cotton is 50% of moisture absorption, and this polyurethane fiber can be almost 100% wet, and the rate of moisture release is extremely fast. That is, the fiber absorbs moisture from the skin in a sports or high-temperature environment, and in a static or low-temperature environment, it can quickly release moisture and reappear moisture absorption performance. Therefore, this kind of fiber is also called "breathable fiber." Fine denier polypropylene fiber: "wicking effect" is a characteristic of fine-denier fiber fabrics. The finer the wicking effect of polypropylene monofilament fibers, the more pronounced this wicking moisture-permeating effect, and the softer the hand feel. Therefore, the fine-denier fiber fabrics can permeate and breathe, keep the skin dry when worn, have no cool feeling of cotton fabric after sweating, and do not have the sweltering and sweat odor of other synthetic fibers, thereby improving the comfort and hygiene of the fabric. This fiber-woven fabric is very suitable for making sportswear for outdoor activities such as hiking and hiking. High-dehumidification, four-channel polyester fiber: DuPont's Tefra-Channel polyester fiber for the production of coolmax fabrics with excellent wicking ability. The hydrophobic synthetic fiber is made into high moisture-conducting fiber. Highly sweaty sweat on the skin is wicked into the surface of the fabric to evaporate and cool. Experiments have shown that the percentage of moisture removal after 30 minutes is 52% for cotton and 95% for four-channel polyester fibers. The sportswear made with it can keep the skin dry and comfortable, and has excellent warmth and cold resistance. Polyester porous hollow cross-section fiber: The purpose of WELLKEY fiber development is to use liquid sweat as a target to achieve thorough sweat absorption and quick drying. WELLKEY is a polyester hollow fiber, and from the fiber surface, there are many pores penetrating into the hollow portion, and liquid water can penetrate from the fiber surface to the hollow portion. This type of fiber mechanism targets the maximum water absorption speed and moisture content, has a unique style of excellent sweat absorption, quick-drying and dryness, and is more suitable for lining of sportswear or sportswear.
