| 中文摘要: |
| 介绍高强型高模量低收缩（HMLS）涤纶工业长丝的生产工艺，通过调整和优化工艺，提高聚酯切片的特性粘度，改善分子结构，生产出了二代和三代HMLS涤纶工业长丝。研究了HMLS涤纶工业长丝在高温受热条件下物理性能的变化。与一代HMLS涤纶工业长丝相比，三代HMLS涤纶工业长丝的耐热性能提高，热强损失降低。 |
| 英文摘要: |
| The production process of high tenacity，high modulus and low shrinkage （HMLS） polyester filament was introduced.Through adjusting and optimizing the process，the intrinsic viscosity of polyester chip increased，the molecular structure was improved，and the second and third generations of HMLS polyester filament were produced.The change of physical properties of HMLS polyester filament under high temperature condition was investigated.Compared with the first generation HMLS polyester filament，the heat resistance of the third generation filament was improved，and the heat stress loss decreased. |
