摘要
为了改善黏胶纤维的弹性恢复性,将黏胶纤维与羊毛角蛋白(Ker)结合,通过在角蛋白溶液中加入渗透剂(JFC)和交联剂(戊二醛,GA),探究不同工艺条件下黏胶纤维弹性恢复能力提升的机理。对整理后的黏胶纤维进行表面观察、结构分析和弹性恢复率测试。结果表明:Ks整理的黏胶纤维能够形成良好的弹性恢复性;KJs整理中较多的角蛋白进入纤维内部,范德华力和氢键的结合量增加,有利于形变的恢复;KJGs整理中既有范德华力和氢键结合增量又有交联的共价键,阻止大分子间形变的产生,也有利于形变的恢复。随着角蛋白浓度的增加,与Ks整理相比,KJs整理的黏胶纤维的弹性恢复率提高量(R2-R1)逐渐增加且趋于稳定,当角蛋白浓度为25 g/L时,(R2-R1)达到极大;与KJs整理相比,KJGs整理的黏胶纤维的弹性恢复率提高量(R3-R2)也逐渐增加且趋于稳定,但增加的速度和稳定值与(R2-R1)有一定区别,当角蛋白浓度为30 g/L时,(R3-R2)达到极大。该结果为进一步改善黏胶纤维的应用性能提供了解决方案。
In order to improve the elastic recovery of viscose fiber,the viscose fiber was combined with wool keratin(Ker).The mechanism of improving the elastic recovery of viscose fiber under different technological conditions was explored by adding penetrating agent(JFC)and crosslinking agent(glutaraldehyde,GA)into keratin solution.The surface observation,structure analysis and elastic recovery rate of the treated viscose fiber were tested.The results show that the viscose fiber treated by Ks can form a good elastic recovery property;more keratin enters into the fiber,and the combination of van der Waals force and hydrogen bond increases,which is conducive to the recovery of deformation;in KJGs finishing,there are both van der Waals force and hydrogen bond combination increment and cross-linked covalent bond,which can prevent the formation of deformation between macromolecules,and also conducive to the recovery of deformation.With the increase of keratin concentration,the increase of elastic recovery rate(R2-R1)of KJs for Ks gradually increases and tends to be stable.When the concentration of keratin is 25 g/L,(R2-R1)reaches a maximum,and the increase of elastic recovery rate(R3-R2)of KJGs for KJs gradually increases and tends to be stable,but the increase speed and stability value are different from that of(R2-R1).When the concentration of keratin is 30 g/L,(R3-R2)reaches to a maximum.The results provide a solution for further improving the application performance of viscose fiber.
