摘　　要：为改善毛织物的防毡缩性能,选用皮层为低熔点聚合物的皮芯复合ES纤维分别以不同的比例和羊毛混纺,采用有热处理和无热处理2种工艺对上述织物进行后整理,并通过扫描电镜观察经过热处理的纤维、纱线和织物内部的黏结情况,测试了纤维的最大黏结强力、纱线的收缩率和织物的洗涤收缩率。结果表明:混有ES纤维的羊毛织物经过热处理,防毡缩性能得到了有效的提高,洗涤收缩率测试结果达到了国际羊毛局(IWS)性能测试标准TM31的要求。A low melting point bi-component sheath-core fiber （ES fiber） was used different blend ratios and then the blended fabrics were treated by thermo setting to blend with wool at and non-thermosetting processes respectively. Electron scanning microscope （SEM） was used to observe the bonding inside the fiber, yam and fabric after thermosetting treatment, and the maximum bonding force between ES fiber and wool, shrinkage of the yam, and the shrinkage of the fabric after washing were tested. The results showed that the wool fabrics containing ES fiber have better anti-felting properties after thermosetting. The shrinkage percentage of the wool/ES fiber blended fabrics meets the criterion of IWS TM31 for washable assessment.
