摘要：

为探讨凉爽锦纶纤维的热湿性能，测试分析了纤维的细度不匀、拉伸性能、摩擦抱合性能、沸水收缩率和含油率等基本性能；在此基础上，通过差热分析、热重分析、降温实验、吸湿实验和放湿实验分别研究了凉爽锦纶纤维的热性能、降温性能和吸放湿性能。结果表明，凉爽锦纶纤维的细度不匀、拉伸性能和摩擦抱合性能比普通锦纶略差，沸水收缩率和含油率与普通锦纶相似；凉爽锦纶纤维的差示扫描量热曲线与普通锦纶存在一定差异，在织造、染整等加工过程中的控制温度应低于370 ℃；凉爽锦纶纤维的降温性能、吸放湿性能均优于普通锦纶。

Abstract:

In order to analyze the heat-moisture performance of cool polyamide filament, the basic performance such as fiber fineness unevenness, tensile performance, friction performance, shrinkage rate in boiling water and oil content were tested and analyzed first. Based on this, the thermal performance, cooling performance, moisture absorption and liberation performance of cool polyamide filament were studied respectively by differential scanning calorimeter, thermal gravimeter analysis, cooling test, moisture absorption and liberation test on the basis of basic performance test and analysis. The results show that the fineness unevenness, tensile performance and friction performance of cool polyamide filament is relatively poor compared with ordinary polyamide filament, but the shrinkage rate in boiling water and oil content are close to ordinary polyamide filament. Differential scanning calorimetry curve of cool polyamide filament has some difference with ordinary polyamide filament. During the process of weaving, dyeing and finishing, the control temperature of cool polyamide filament should be lower than 370 ℃. The cooling performance, moisture absorption and liberation performance of cool polyamide filament are better than ordinary polyamide filament.
