C型截面中空涤纶长丝的碱减量加工工艺研究
|
摘要
为改善普通涤纶长丝保暖、蓬松等性能,获得异形化、功能性的中空涤纶长丝,分别利用单因子试验和正交试验研究了碱液质量浓度、处理浴温度和保温时间对C型截面中空涤纶长丝减重率和力学性能的影响。得出C型截面中空涤纶长丝的最佳碱减量加工工艺方案:处理浴碱液质量浓度为15.5 g/L,处理浴温度为100℃,保温时间为25 min。通过实际试验对最佳碱减量加工工艺方案进行验证,结果表明,处理后得到的C型截面中空涤纶长丝的减重率达到40.07%,并且其中空形态清晰、C型截面良好且断裂强力损失率下降为42.10%(<45.00%),满足设计要求。
In order to improve the warmth retention and fluffy properties of ordinary polyester filament, the special-shaped and functional hollow polyester filament was fabricated. The effects of alkali liquor concentration, bath temperature and holding time on the weight loss and mechanical properties of hollow polyester filament with C-type section were studied respectively by single factor tests and orthogonal tests. The results show that the optimum process parameters for the fabrication of C-type hollow polyester filament are 15.5 g/L of the mass concentration of alkali solution, 100 ℃ of the bath temperature and 25 min of the holding time. Then the optimum process parameters were verified by experiments,and the results show that the weight loss rate of C-type hollow polyester filament reaches 40. 07% after treatment. Besides,the polyester filament has clear hollow structure and good C-type section,and its breaking strength decreases by 42. 10%( < 45. 00%),which could meet the design requirements.
