PU革基布退浆染色一浴工艺探讨

Discussion about One-bath Dyeing Method on PU Leather Fabric

文章分别采用碱退浆染色二浴、酶退浆染色二浴及酶退浆染色一浴工艺对T/C混纺PU革基布进行处理,测试染色织物的K/S值和染色牢度。结果表明,酶退浆染色一浴工艺织物得色深、染色牢度符合要求且重现性较好。

T/C blended PU leather fabric was dyed with Two-bath dyeing alkali desizing,two-bath dyeing enzyme desizing and one-bath dyeing enzyme desizing,then dyed fabrics′K/S value and color fastness was tested.Results show that the fabrics which dyed by one-bath dyeing enzyme desizing meet the requirements of color depth and color fastness and have anadvantage on reproducibility.
