家庭洗涤对免烫棉织物性能的影响

为探究多元羧酸免烫棉织物在日常洗涤过程中免烫性能的保持情况,实验模拟了日常家庭洗涤的环境,对免烫棉织物在不同的洗涤助剂类型、不同洗涤温度、不同洗涤次数下进行洗涤处理。通过测试对比原免烫织物和不同方式洗涤后免烫棉织物的折皱回复角、断裂强力和化学结构表面形貌等,对免烫棉织物的免烫性能在洗涤过程中的保持能力进行分析。结果表明:经重复洗涤,免烫棉织物的断裂强力和折皱回复角都呈现出不同程度的降低;纤维的表面形貌及微观结构都产生了一定的变化;经80 ℃混合溶液重复洗涤处理50次后的断裂强力下降约26%,折皱回复角降低约50%;对免烫棉织物而言,在家庭洗涤过程中,高温复合重复洗涤对其免烫性能的破坏作用较大。

Effect of household washing on properties of anti-creasing cotton fabrics

In order to study the maintenance of anti-creasing property of polycarboxylic acid anti-creasing treated cotton fabrics in the daily washing process,experiments were carried out to simulate the environment of daily household washing, where the anti-creasing cotton fabrics were washed under different detergent types, different wash-temperatures, and different wash-times. The wrinkle recovery angle, breaking strength and surface morphology of the original and post-washing fabrics were tested and compared, and the anti-creasing property of anti-creasing cotton fabrics during the washing process was analyzed.The results of the study show that after repeated washing, the wrinkle recovery angle and breaking strength of anti-creasing cotton fabrics are reduced, and the surface morphology and microstructure of the fibers demonstrate certain changes. After repeated washing of the mixed solution at 80 ℃ for 50 times, the breaking strength is reduced by about 26%, and the wrinkle recovery angle of the sample is reduced by about 50%. For anti-creasing cotton fabrics in the household washing process, high-temperature composite repeated washing show a greater destructive effect on its anti-creasing property.
