| titleOfInvention | Spandex fibre and its manufacture method with good chlorine resistance and discoloration-resistant |
| abstract | The present invention is intended to provide spandex fibre and its manufacture method with good chlorine resistance and discoloration-resistant, so as to solve when the chlorine fastness spandex fibers of the prior art using inorganic chlorine-resistant agent are positioned in air, the fiber is easy to the performance of discoloration, and solves the problems, such as chlorine-resistant effect time short or of short duration phenomenon and lose spandex fibre inherent characteristic.The method of the invention is characterized in that, in the manufacturing process of conventional chlorine fastness spandex fibers, following material is added into the slurry of polyurethane solutions and is mixed to manufacture spinning solution, after defoaming, there is the spandex fibre of good chlorine resistance and discoloration-resistant by dry spinning and convolute manufacture：As the organic additive for improving chlorine resistance selected from least one of two hindered hydroxyphenyl group compound of symmetry and single hindered hydroxyphenyl group compound compound, the additive comprising the diaminourea carbamide compounds with heat resistance and free radical scavenger and the urethanes additive comprising the tert-butyl group for playing the role of secondary antioxidants. |
