棉织物抗紫外线剂QH-3958的应用

Application of anti UV agent QH-3958 on cotton fabric

在后整理工序中应用抗紫外线剂QH-3958对棉织物进行抗紫外线整理,以二浸二轧、预烘、烘干、焙烘工艺整理后的棉织物性能测试数据为依据,优化抗紫外线剂QH-3958整理棉织物的用量。结果表明:经过50~60 g/L抗紫外线剂QH-3958整理后,棉织物的紫外线透过率大幅降低,赋予棉织物抗紫外线功能以及柔软手感,颜色色光变化较小,耐酚黄变效果可达4级,可以为车间实际大生产应用提供参考。

The anti UV agent QH-3958 was applied to cotton fabrics for anti UV finishing in the post fin⁃ishing process.Based on the performance test data of cotton fabrics treated under the process conditions of two immersion and two rolling,pre drying,drying,and baking,the amount of anti UV agent QH-3958 used for cotton fabric finishing was optimized.The results showed that the UV transmittance of cotton fabric could be significantly reduced after being treated with 50-60 g/L anti UV agent QH-3958,giving cotton fabric anti UV function and soft feeling.The color and light change was small,and the phenolic yellowing resistance effect could reach level 4,which providing reference for practical large-scale production applications in the workshop.
