Cotton is irreplaceable for its breathability, comfort and environmental friendliness,so in many products we add a certain percentage of cotton.However,as the seamless garment  industry in China is very developed now, there is no cotton in the thermal underwear, but fibers blended with nylon, spandex, and polyester.


Nylon is also called Polyamind or Polyaminde , and many customers only write abbreviations “PA”.It is used widely in seamless women’s fitness bra,seamless women’s yoga legging,seamless women’s sport hoodie, and also seamless running workout tank top,ect.

Polyester is the world’s largest synthetic fiber, exceeding acrylic. We usually use ordinary polyester, many of them only written  abbreviated “PET ” or “PL”,and we need  pay attention to understanding correctly. Polyester is generally blended with other fibers. Many garments are written with a percentage of polyester fiber, which refers to the actual  polyester.

Because the amount of polyester is relatively large used in the world, they do not want people to think that this is a low-end faber. Sometimes customers also specify high-grade polyester. The high-grade polyester commonly used by our company is a brand of DuPont(Now sparate INVISTA), called Coolmax,widely used in women’s gym wear and men’s athletic wear suppliers in China.


PU Polyurethane is a polyurethane fiber, Elastane fiber, also known as Spandex. Famous brands are  including Lycra (United States, United Kingdom, Netherlands, Canada, Brazil), Neolon (Neolon, Japan), Doralan (Dorlastan, Germany) and so on. Lycra is commonly used in women’s fitness wear in China.Lycra, spandex yarn, polyester spandex, is a brand of DuPont, a very magical material. Lycra (LYCRA) can be stretched 4 to 7 times freely and quickly return to its original length after the external force  released. Some of our women’s slim body shaper series have Lycra ingredients.  


Viscose fiber, including a variety of matte silk, viscose, rayon, artificial hair, etc., the most well-known, we are using modal fiber Modal.Modal is a cellulose-recycled fiber of high-moisture modulus viscose fiber developed by Lenzing, Austria. The fiber is made from European
eucalyptus, which is made into wood pulp and then processed into fiber by a special spinning process.

6.Polypropylene fiber

Polypropylene fiber is a Chinese brand name of synthetic fiber, isotactic polypropylene fiber made from propylene, a by-product of petroleum refining.

The characteristics of polypropylene are as follows: ① The longitudinal surface is straight and smooth②The density is light, only 0.91 g/m³; ③ The strength is strong, and the elasticity is excellent.Also the wear resistance is good;  The wet strength is basically equal to the dry, and it is the ideal material for making fishing nets and cables; ④The effect of moisture absorption and perspiration is obvious; ⑤ The dyeability is very poor; ⑥ Corrosion resistance, but poor light resistance, poor thermal stability, and easy to be older that is not resistant to ironing; ⑦ Its high strength is  the second  rank to nylon,but  the price is much lower than nylon. The fabric made of polypropylene is dimensionally stable and has good abrasion resistance. Therefore, polypropylene is often used to weave carpets.

7.Bright Yarn

This is a functional fiber. It is made of polyester according to the material.And some is made from  nylon.It appears bright if we use bright yarn.So many customers wold like to study new designs. Therefore, it is popular knitted into women’s activewear,yoga bra,strappy bra, sport leggings,ect.
