Levafix CA高日晒活性三原色轧染适用性测试

通过分析Levafix CA高日晒活性中浅色三原色的渗透性、比移值、耐盐碱性、配伍性等性能，采用轧染工艺多次染色做效果对比，最后对轧染色布进行牢度测试，结果表明：LevafixCA高日晒活性三原色具有良好的渗透性、配伍性，对盐碱上染影响一致，同步上色性、染色稳定性好，色布日晒牢度达到5级以上，汗光牢度达到4级以上，且其他色牢度不会降低，适合轧染染拼色。

Suitability test for Levafix CA high light trichromatic reactive dyes

The permeability, Rr value, saline-alkaline resistance and compatibility of Levafix CA high light reactive dyes in mid-light primary colors were analyzed. The effect of multi-dyeing via pad dyeing process was compared. The fastness of pad-dyed fabrics was finally tested. Results showed that Levafix CA high light trichromatic reactive dyes exhibit good permeability, compatibility, synchronous coloring and dyeing stability, and its influences on saline and alkaline dyeing is consistent. It was suitable for color matching by pad dyeing, for the light fastness and perspiration-light fastness reached above 5 grade and 4 grade respectively and other fastnesses did not decrease.
