What Kind of Fabric Is the Spandex? What Are Shining Points of Clothes Made of Spandex?

What kind of fabric is the spandex?

Spandex is a kind of polyurethane fiber. Because of its excellent elasticity, it is also known as the elastic fiber, which has been widely used in clothing fabrics. The main characteristics of spandex fabric are:
(1) The elasticity of spandex is very high. In general, products do not use 100% polyurethane, and in most cases, 5% to 30% polyurethane is blended in the fabric, giving a rise to a variety of spandex fabrics that boast 15% to 45% of the comfortable elasticity.
(2) The spandex fabric is often made of composite yarn. It means that spandex is the core and other fibers (such as nylon, polyester, etc.) are the cortex to make covering yarn elastic fabric, which boasts good adaptability to the body and is the ideal raw material for tights, giving no sense of pressure.

(3) The appearance style and wearability of spandex elastic fabric are close to those of the like products such as its coated outer fiber fabric.


What are the shining points of clothes made of spandex?

1. The biggest advantage of spandex fabric is its good elasticity, which can be stretched 5 to 8 times with no aging. Spandex can not be woven alone and is generally woven with other raw materials. The content of spandex is about 3 to 10%, and that in swimwear fabric can reach 20%.


2. Spandex fiber is a synthetic fiber with high elongation at break (over 400%), low modulus and high elastic recovery rate. It is the Chinese trade name of multi-block polyurethane fiber, also known as elastic fiber. Spandex has high elongation (500% to 700%), low elastic modulus (200% elongation, 0.04 to 0.12 g/denier) and high elastic recovery rate (200% elongation, 95% to 99%). Its physical and mechanical properties are very similar to those of natural latex wire except for its high strength. It is more resistant to chemical degradation than latex silk, and has moderate thermal stability with a softening temperature of about 200℃ or more. Most dyes and finishing agents used in synthetic and natural fibers are also suitable for dyeing and finishing spandex. Spandex is resistant to sweat, seawater and various dry cleaners and most sunscreens. It will also fade with long-term exposure to sunlight or chlorine bleach, but the degree of fading varies greatly with the type of spandex. Spandex is a polyurethane fiber. Because of its excellent elasticity, it is also known as the elastic fiber, which has been widely used in clothing fabrics with characteristics such as high elasticity. Spandex fabric is mainly used in the manufacture of tights, sportswear, protective straps and soles. Its varieties according to the needs of use, can be divided into warp elastic fabric, weft elastic fabric and warp and weft bi-directional elastic fabric.


The Characteristics of Spandex Fiber Fabric and the Application of Spandex


Spandex is a kind of polyurethane fiber. Because of its excellent elasticity, it is also known as the elastic fiber, which has been widely used in clothing fabrics.


1. The main characteristics of spandex fiber fabric


(1) The elasticity of spandex is very high. In general, products do not use 100% polyurethane, and in most cases, 5% to 30% polyurethane is blended in the fabric, giving a rise to a variety of spandex fabrics that boast 15% to 45% of the comfortable elasticity.


(2) The spandex fabric is often made of composite yarn. It means that spandex is the core and other fibers (such as nylon, polyester, etc.) are the cortex to make covering yarn elastic fabric, which boasts good adaptability to the body and is the ideal raw material for tights, giving no sense of pressure.


(3) The appearance style and wearability of spandex elastic fabric are close to those of the like products such as its coated outer fiber fabric.


2. The application of the spandex

(1) Spandex fiber can be used for the manufacture of clothing that can be stretched to meet comfort requirements. For example: Professional sports clothes, workout clothes and exercise clothing, diving suit, bathing suit, bathing suits for game, basketball clothes, bra and condole belt, ski pants, clothes for disco, jeans, casual pants, socks, leg warmers, diapers, tight pants, belt, underwear, jumpsuits, spandex close-fitting clothing, bandages used by male ballet dancers, protective clothing for surgery, protective clothing used by support units, short sleeves for bike-riding, wrestling vest, suit for boating, underwear, performance clothing, qualitative clothing, brassiere, home decorations, micro-bead pillow, etc.


(2) Spandex is rarely used in general clothing. In North America, it is used less on men's clothing and more on women's clothing. Because women's clothes are required to be more close to the body. In use, it will be blended with a large number of other fibers such as cotton and polyester in order to reduce the gloss to a minimum.
