Description

technical field

[0001] The present invention relates to a spandex fiber with excellent chlorine resistance and its manufacturing method, more specifically, it relates to the following spandex fiber and its manufacturing method: it contains symmetrical double hindered phenolic additives and inorganic chlorine resistant agent, thereby While maintaining the physical properties of the original polyurethane polymer, it also improves its chlorine resistance. Background technique

[0002] Spandex is a representative polyurethane elastic fiber, which can maintain a high degree of elasticity and has excellent physical properties such as tensile stress and recovery force, so it can be widely used in underwear, socks, sports and leisure clothing, etc., but as spandex The physical properties of polyurethane, the main component, will be greatly reduced during chlorine bleaching. Therefore, if you wear a swimsuit made of spandex and nylon in a swimming pool with an active chlorine content...
