The reason why fabrics containing spandex are prone to yellowing
Spandex is a commonly used fiber variety in our daily lives, characterized by good elasticity, low fineness, high elastic modulus (cracking elongation can reach 400-800), and low specific gravity. Spandex can be blended with textile fibers such as nylon, wool, cotton, polyester, acrylic, and viscose to create a soft and elastic fabric. It is widely used in fitness wear, swimwear, jeans, leggings, underwear, jumpsuits, and underwear. Because women have higher requirements for close fitting clothing, spandex fabric is more favored by women.
For example, in lace fabrics (including spandex) that women cannot resist, wearing or placing them for a long time can easily cause yellowing. What is the reason for this?
Because spandex molecular chains contain a large number of reactive groups such as amino groups, they are prone to yellowing during high-temperature setting or storage, which affects the quality of products, especially fluorescent whitening fabrics and light colored fabrics. Because spandex uses silicone oil lubricants and other additives during the weaving process to improve its spinning performance. These additives will naturally degrade over time, causing the fibers to turn yellow. In addition, spandex itself is not easy to color, which means that conventional dyes cannot color spandex. Therefore, after dyeing the fabric, if the restoration and cleaning are not sufficient, the so-called yellowing phenomenon may also occur.
