(Summary description)Women's recycled spandex flat pants from China tell you that spandex is short for polyurethane fiber, which is an elastic fiber. Women's recycled spandex flat pants from China tell you that spandex is generally composed of multiple filaments, generally 10D/pants, and now there are 15D/pants, or even 20D/pants, the less the number of theoretical strands, the better the uniformity of evenness. The chances of overlapping patterns are less.

Women's recycled spandex flat pants from China tell you that the product solution of dry spinning DMAC is harmful to the liver of the human body. Generally, 10D/root contains 0.5mg/kg, and 15D/root contains 0.7mg/kg, exceeding the standard. When producing Spandex, special attention must be paid to coiling tension, count on the tube, breaking strength, breaking elongation, forming degree, oil adhesion, elastic recovery rate, etc. These problems directly affect weaving, especially knitting production Pay more attention to single-sided cloth.
Women's recycled spandex flat pants from China tell you that it is highly elastic and can be stretched 6-7 times, but it can quickly return to their original state as the tension disappears. Its molecular structure is a chain-like, soft and extensible polyurethane, and its properties are enhanced by connecting hard segments together.
Through the above introduction and analysis of the Women's recycled spandex flat pants from China introduces spandex, hope it helps you.
