氨纶丝常见断丝原因分析及解决办法

Causesof Spandex Filament Break and Their Analysis

断丝是氨纶丝应用过程中常见的一个问题,是影响布面品质的一个重要因素。本文从氨纶丝织造过程中的断丝和布面断丝两方面系统阐述造成氨纶丝断丝的原因,其中,织造过程中的断丝主要有掉边断丝、叠绕断丝、氨纶丝反绕断丝和氨纶丝拉伸断丝;布面断丝包括物理性断丝和化学性断丝两类。详细讨论了各种断丝的表现形式和产生原因,并根据实际生产经验提出正确选择氨纶丝、合理控制车间温湿度、以及严格规范操作对避免氨纶丝断丝十分重要。

Spandex filament break is a common problem in application process, and also is an important factor impacting on the quality of fabric. The paper systematically expounds the main reasons causing spandex filament break in terms of two aspects including knitting process break such as edge dropping, overlapping, rolling-back and pulling break, and fabric surface break such as physical and chemical break. In addition, it also analyzes in detail the forms of every kind of spandex filament break. Finally, based on practical experience, it concludes the main methods to avoid spandex filament break, such as choosing the right spandex, controlling moisture and tem-perature of workshop reasonably and carrying out the operation specification strictly and so on.
