It is essential to understand the yarns which will use in seamless clothing to understand what function will the custom fitness apparel give, here we will understand the 5 types of yarns that commonly used in seamless clothing.
It is easily to see the washing label writing with “spandex” in a big percent of seamless clothing. Why? Spandex is the abbreviation of polyurethane fiber and is an elastic fiber. It is highly elastic and can be stretched 6 to 7 times, but also can quickly return to its original position with the disappearance of tension.
Spandex has excellent elasticity. The strength is 2 to 3 times higher than that of latex yarn, the linear density is also thinner, and it is more resistant to chemical degradation. Spandex has good acid and alkali resistance, sweat resistance, seawater resistance, dry cleaning resistance, and abrasion resistance.
The second common material you will see on the washing label will be polyester.
Polyester fiber, commonly known as “dacron”. It is a kind of synthetic fiber, PET fiber for short, which is made of organic dihydric acid and dihydric alcohol.
The greatest advantage of polyester fiber is wrinkle resistance and its shape retention is very good, with a high strength and elastic recovery ability. Its fast and durable, wrinkle-resistant; ironing-free; non – sticky hair.
Developed by a team led by the eminent American scientist Carothers, nylon is the world’s first synthetic fiber, a term for polyamide fiber. Provides functions in producing seamless clothing.
Polyamide is mainly used in synthetic fiber, its most prominent advantage is the wear resistance is higher than all other fibers, than cotton wear resistance 10 times higher, than wool 20 times higher, in the blend fabric a little bit of polyamide fiber, can greatly improve its wear resistance; When stretched to 3-6%, the elastic recovery rate can reach 100%. Can withstand thousands of times without breaking.
The most simple material for end-users to understand is cotton. It gives customers the natural feeling for garments with its comfortable wearing sense. It usually used as the main material in custom fitness apparel combined with other fibers.
Healthy, Simple, Comfortable are the main features for cotton. Cotton fiber has high strength, good permeability, poor wrinkle resistance and poor tensile strength. Good heat resistance; Poor acid resistance, at room temperature resistance to dilute alkali; It has good affinity for dyes, easy to dye, variety choosing range on colors.
Viscose fiber, referred to as viscose fiber for short, is a cellulose fiber obtained by extracting and reshaping fiber molecules from natural wood cellulose using “wood” as a raw material.
The hygroscopicity of viscose fiber meets the physiological requirements of human skin. It has the characteristics of smooth and cool, breathable, anti-static, anti-ultraviolet, bright colors, and good color fastness. In Gym wear viscose is helping to make the wearing more breathable and cool.
Except these 5 main material, there are also materials like Polypropylene fiber，Bright Yarn, Cold Yarn, Socotex etc join in the production of fitness clothing, and there are always the renewing technology and materials coming up in this field!
