Spandex is a common fabric in life. It is often used to make bedding or other fabric products at home, but many people are not familiar with the material of spandex. Let's work with Sihai Xiaobian to understand the characteristics and advantages of spandex fabric!
What is spandex
Spandex is a kind of polyurethane fiber, which is also known as elastic fiber because of its excellent elasticity. It has been widely used in garment fabrics and has the characteristics of high elasticity. It is mainly used in the manufacture of tight clothing, sportswear, body belt and sole. Its varieties can be divided into warp elastic fabric, weft elastic fabric and warp weft two-way elastic fabric according to the needs of application.
What is spandex fabric
At present, the fabrics are mostly natural fibers and artificial fibers. For example, cotton is a kind of natural fiber, which has good air permeability and moisture absorption, but it has poor elasticity and is easy to deform. Artificial fiber, as the name suggests, is a kind of fiber synthesized according to demand, which solves some shortcomings of natural fiber. Spandex is a kind of polyester fiber of artificial chemical synthetic fiber, which is also called elastic fiber because of its excellent elasticity. Clothing fabrics are generally mixed with different proportions of spandex to increase elasticity and comfort, which is widely used.
Characteristics of spandex fabric:
1. The elasticity of spandex is very high. Generally, 100% polyurethane is not used in products, and the proportion of 5 ~ 30% is mostly mixed in fabrics. All kinds of spandex fabrics have 15% ~ 45% comfortable elasticity.
2. Spandex fabrics are often made of composite yarn, that is, spandex is used as the core and other fibers (such as nylon, polyester, etc.) are used as the skin to make core spun yarn elastic fabrics. They have good adaptability to the body and are very suitable for making tight clothes without pressure.
3. The appearance style and wearing performance of spandex elastic fabric are similar to those of the coated outer fiber fabric.
Advantages of spandex
1. It has large stretching property, good shape retention, and no wrinkling;
2. Feel soft, smooth, elastic, comfortable, considerate and fit;
3. Acid and alkali resistance, wear resistance and aging resistance;
4. It has good dyeability and should not fade.
Spandex disadvantages
1. Poor moisture absorption;
2. Spandex is usually not used alone, but blended with other fabrics
3. Poor heat resistance
Washing and maintenance of spandex fabric:
Spandex fabric has good elasticity and is not easy to age and deform. At the same time, it is more resistant to sweat and sea water. However, long-time immersion, high-temperature washing and bleaching water washing will still lead to fading and discoloration of clothes. In particular, spandex is often blended with other fabrics, such as cotton spandex, which should be paid special attention in the process of cleaning and maintenance.
