丝素蛋白整理对针织物起毛起球性的影响

Influence of Silk Fibroin Finishing on Pilling Resistance of Knitted Fabric

以天然蚕丝为原料提取再生丝素蛋白溶液,用浓度为5%丝素蛋白溶液对针织物进行整理,分析了整理前后织物的起毛起球过程,并采用主观评级法、单位面积毛球个数法、单位面积毛球称重法对整理前后织物起球性进行评价。结果表明,未经丝素蛋白溶液整理的织物起毛起球现象较明显;经浓度为5%丝素蛋白溶液整理后,抗起毛起球性得到明显地改善,摩擦100次时,起球级别可以提高到4级,毛球数量也相应减少,但毛球质量下降不明显。

With natural silk as raw material, regenerated silk fibroin solution was extracted, and knitted fabrics were finished by 5% silk fibroin solution. The processes of fuzzing and pilling of the fabric before and after finish-ing were analyzed, and pilling of the fabric before and after finishing was evaluated by the methods of subjective rating, hair ball number per unit area and weight method of hair ball per unit area. The results show that pilling phenomenon of knitted fabric without the finishing of silk fibroin is more obvious; Pilling Resistance of knitted fab-ric finished by 5% silk fibroin is improved obviously, and after 100 times friction test, pilling resistance can reach level 4, the number of hair ball reduces, but the decrease of hair ball’s quality is not obvious.
