摘要：

为系统分析生物基锦纶56与锦纶66的吸放湿性能,在标准状态下对不同规格纤维进行对比研究。测试了生物基锦纶56、锦纶66弹力丝及短纤维的吸湿、放湿和干燥特征曲线,并由此推导出4种纤维在标准状态下达到吸湿、放湿和干燥平衡过程中,回潮率或含水率对时间的回归方程,以及吸湿、放湿和干燥速率方程。结果表明:标准大气条件下,与锦纶66相比,生物基锦纶56的吸湿、放湿平衡回潮率大,吸湿、干燥速率大,初始放湿速率略小,但随着时间的延长,生物基锦纶56的放湿速率大于锦纶66;4种纤维的吸湿等温线均呈反S形,在高湿度环境下生物基锦纶56的干燥性优于锦纶 66,即生物基锦纶56具有较好的快干性能。

Abstract:

Aiming at the analyse of moisture absorption and liberation properties of bio-based polyamide 56 and polyamide 66, characteristic curves of moisture absorption and liberation, and drying of bio-based polyamide 56 draw texturing yarn (DTY), polyamide 66 DTY, bio-based polyamide 56 and polyamide 66 staple fiber were obtained by testing under the standard condition. According to the characteristic curves, the regression equation of moisture regain or moisture content to time were deduced during the moisture absorption, liberation and drying equilibrium process for the four types of fibers under the standard testing conditions. The results show that under standard atmospheric conditions, bio-based polyamide 56 fiber has a higher moisture absorption and liberation balance, higher moisture absorption and drying rates, and a slightly lower initial moisture release rate compared with the polyamide 66 fiber. However, bio-based polyamide 56 has a higher moisture release rate than polyamide 66 with the increase of time. The moisture absorption isotherms of the four types of fibers are all in a reverse "S" shape. In a high humidity environment, the drying property of bio-based polyamide 56 is better than that of polyamide 66, i.e., bio-based polyamide 56 has better quick-drying performance.

Key words: bio-based polyamide 56, polyamide 66, fiber structure, moisture adsorption property, moisture liberation property
