Background technique

Stretch fabrics widely used in the market today, especially those containing highly elastic fibers such as spandex, although excellent in providing excellent stretch and comfort, have problems in terms of elastic stability. During use, these fabrics may lose their elasticity due to factors such as multiple washings, wearing and stretching, resulting in impaired appearance and performance of the fabric. This will not only affect the appearance and quality of the product, but may also have a negative impact on the user experience and reduce the market competitiveness of the product.

In order to solve this problem, the existing technology has tried many methods, including changing the composition, structure and morphology of fiber materials, using different processing techniques and chemical treatments, etc. However, these methods all have some limitations, such as improving the elastic stability may affect the comfort and softness of the fabric, or need to use some environmentally friendly chemical agents. Therefore, it is necessary to find a more efficient, reliable and environmentally friendly solution to improve the elastic stability of elastic fabrics, so as to meet the needs of the market and consumers.
