| titleOfInvention | A finishing method for improving the yellowing resistance of polyester yarn |
| abstract | The invention proposes a finishing method for the anti-yellowing performance of polyester yarn, which includes loosening, reversing, filling a cylinder, curing, washing, dehydrating, rewinding, testing, and packaging; the invention adopts Guangzhou Hengjin Chemical Technology Co., Ltd. The company's anti-yellowing agent HJ‑326GH, the curing condition is to add anti-yellowing auxiliary agent solution in the dye vat, and the anti-yellowing auxiliary agent solution includes: water, anti-yellowing agent, and acidic buffer; The pH of the anti-yellowing auxiliary solution is 4-5, the bath ratio is 1:10-15, the amount of the anti-yellowing auxiliary agent is owf 0.5-4%, the temperature in the cylinder is 15-25 ℃, and the time is 20- 30 minutes. The invention performs anti-yellowing finishing on the polyester yarn, avoiding the influence of the yellowing of the polyester yarn during transportation and storage; using a flat temperature treatment process, the process is simple, convenient and energy-saving; it is suitable for white polyester and color spinning polyester. Anti-yellowing finishing with recycled polyester for a wide range of applications. |
