摘要
为了探讨天然彩丝织物丝胶与色素的保留方法,使用聚乙二醇二缩水甘油醚(PEGDE)为固色剂,CaCl_(2)为催化剂,浸轧烘焙为固色工艺,采用单因素实验的方式,探究了最佳的固色条件,对织物的常用性能进行了分析。结果表明:固色剂质量分数15%、烘焙温度140℃、烘焙时间17 min及CaCl_(2)质量分数4%为最佳工艺条件。处理后的织物力学性能与刚柔性变化不大;折痕回复性能提高;颜色变化不大,耐水洗颜色稳定性提高。该整理方法绿色环保且效率高,在工业生产中具有良好的应用前景。
To study the retention method of sericin and pigment of naturally colored silk fabric,this paper used PEGDE as the crosslinking reagent,CaCl_(2) as the catalyst and padding-baking as the treatment method.Single test method was applied to investigate the optimum treating conditions.Tensile properties,fabric handle and color fastness to repeated washing were tested.The results showed the optimum process conditions are:crosslinking reagent 15%,CaCl_(2)4%,baking for 17 min with 140℃;this method had little effect on tensile property and stiffness,but it improved the crease resistant property;the color fastness of the treated fabric was also improved.This process is eco-friendly and efficient,it has a promising future in the industrial application.
