Product Description
Spandex is an elastic fibre known as polyurethane (PU). It has a high degree of elasticity and can be stretched six to seven times, but with the loss of tension it can quickly return to its initial state. Its molecular structure is a chain-like, soft and elongable polyurethane, which is enhanced by the hard chain segments connected together. Elastane fibres are divided into two categories: one for polyester chains and one for polyether chains. Polyester elastic fibres are more resistant to oxidation and oil; polyether elastic fibres are more resistant to mildew and detergents
Advantage
Spandex has excellent elasticity. And the strength is 2 to 3 times higher than latex yarn, the thread density is also finer and it is more resistant to chemical degradation. Spandex is more resistant to acid and alkali, sweat, seawater, dry cleaning and abrasion.
Production methods
1.DRY SPINNING
2.MELT-SPINNING
3.WET-SPINNING
4.Chemical reaction method
Storage method
Spandex should be stored in a constant temperature and humidity environment, between 18-20 degrees Celsius, the lower the temperature, the longer the storage period, the relative humidity of 60%-70%, should not be placed in places exposed to sunlight, should not be stored with sulphur dioxide, nitrogen oxides and other chemical products, resulting in its decomposition.
Storage period: 20D (3 months), 30D (4 months), 40D-70D (6 months), 100D-280D (9 months), thicker than 420D (12 months), the thicker the spandex, the longer the storage period.
When weaving Spandex, the carton is opened at least 16 hours before the weaving workshop to allow for moisture recovery to reduce yarn breakage during weaving.
Application
Spandex is used in garments that need to be stretchable to meet comfort requirements. Examples include: professional sportswear, fitness and exercise clothing, wetsuits, swimming suits, competition swimming costumes, basketball uniforms, bras and suspenders, ski trousers, disco, jeans, casual trousers, socks, leggings, nappies, tights, belts, underwear, jumpsuits, spandex bodysuits, straps for male ballerinas, protective clothing for surgery, protective clothing for logistics troops, short sleeves for cycling, wrestling vests, Suits for boating, underwear, performance costumes, qualitative clothing, etc. For example: bras, home decorations, micro-beaded pillows.
Spandex is used to a lesser extent in general clothing. In North America, it is rarely used in men's clothing and is more often used in women's clothing. This is because women's clothing requires a closer fit. It is used with a large amount of other fibres such as cotton and polyester blends to minimise sheen.
