几种植物染料对黏胶织物的防紫外线功能整理

The UV-resistant finishing of viscose fabrics by several plant dyes

采用黄柏、槐米与茜草中提取的植物染料对黏胶织物进行功能整理。测试表明,黄柏、槐米与茜草中提取的植物染料对远紫外线与近紫外线具有较好的吸收性能。染色后织物的抗紫外线性能均有不同程度提高,其折皱回复角、回潮率与断裂强力不同程度下降,变化幅度与植物染料的上染率呈正相关关系。经摩擦后,黏胶织物与染色皂洗织物相比,折皱回复角、回潮率略高,断裂强力略低,对织物的服用性能影响较小。研究认为:黄柏、槐米与茜草染料对黏胶织物进行防紫外线功能整理具有较强的可行性。

Plant dyes from Cortex phellodendri,Sophora japonica and Madder are applied to UV-resistant finishing of viscose fabric.The tests show that the plant dyes from Cortex Phellodendri Japonica and Madder own better absorption properties to far ultraviolet and near ultraviolet.The UV-resistant properties of viscose dyeings are improved to different degrees,the crease recovery angle,moisture regain and breaking strength are decreased to different degrees,and the range of change is positively correlated with the dyeing uptake of the plant dyes.Compared with the dyeings after soaping,the crease recovery angle and moisture regain of the viscose dyeings after rubbing are slightly highe,and the breaking strength is slightly lower,which shows little influence on the wearability of the fabric.It is concluded that it is feasible to apply Cortex phellodendri,Sophora japonica and Madder to UV-resistant finish of viscose fabric.
