聚乳酸纤维织物服用性能测试与分析

Test and analysis of polylactic acid fabric wearability

为更好地了解聚乳酸纤维织物的服用性能,提高产品开发的针对性,对相近规格的纯聚乳酸纤维织物、聚乳酸纤维/棉(80/20)混纺织物、棉织物、涤纶织物进行强伸度、透气性、折皱回复性、导湿性、悬垂性、耐磨性、起毛起球性、交织阻力等性能的测试。结果表明:聚乳酸纤维织物具有很好的伸长变形能力;其折皱回复性、导湿性、悬垂性和耐磨性良好;透气性和抗起毛起球性不如棉织物;具有较高的交织阻力,可防止织物产生纰裂。聚乳酸纤维/棉混纺织物由于棉纤维的加入改善了聚乳酸纤维织物的透气性和抗起毛起球性,减小打纬阻力,但织物的折皱回复性、悬垂性和耐磨性有所降低。

In order to have a better understanding of the polylactic acid （PLA） fabric wearability and enhance the research and development level of this kind of products, the paper discusses the test of fabric properties such as the strength and elongation, air permeability, wrinkle recovery, moisture transmitting, draping, abrasion resistance, pilling and weaving resistance of pure PLA fabric, the blend fabric in a blend ratio of PLA fiber/cotton （80/20）, cotton fabric and polyester fabric with similar specifications. The result shows that the polylactic acid fabric has good elongation, wrinkle recovery, moisture transmitting, draping property and abrasion resistance. Its air permeability and anti-pilling property are not as good as those of cotton fabrics. It has higher weaving resistance and will prevent the fabric slippage. Due to addition of cotton fibers, the air permeability and anti-pilling property of the blended fabric are improved, weaving resistance is brought down, but wrinkle recovery, draping property and abrasion resistance drop.
