摘　　要：染料转移或串染是服装洗涤过程中的常见问题。文章研究了水硬度、洗涤温度、pH值和聚乙烯吡咯烷酮(PVP)浓度对9种不同结构直接染料转移性能的影响。研究结果表明,直接染料的平面性结构和氢键的形成能力对串染影响较大。水硬度的增加对8种直接染料的转移有促进作用,洗涤温度的增加对7种直接染料的转移有抑制作用,pH值的增加对7种直接染料的转移有促进作用,PVP对所有直接染料的转移均有显著的抑制作用。在服装洗涤过程中,降低水硬度和pH值,适当增大洗涤温度对大部分直接染料的转移可以起到抑制作用。Dyes transfer or color contamination is a common problem in garment laundering.The effects of water hardness,washing temperature,pH value,and polyvinylpyrrolidone(PVP)concentration on the transfer properties of nine different structured direct dyes were studied.The results showed that the flat structure of the direct dyes and the ability of hydrogen bonding have a great influence on color contamination.The increase of water hardness has a positive effect on the transfer of eight direct dyes,while the increase of washing temperature has an inhibition effect on the transfer of seven direct dyes.Increased pH value promotes the transfer of seven direct dyes.And PVP has a significant inhibition on the transfer of all direct dyes.Therefore,reducing water hardness and pH value and properly increasing washing temperature in laundering can inhibit the transfer of most direct dyes.
