Abstract

本发明目的在于，提供染料分散性优异、气味小、并且即使在与通常相比升温速度快的情况下也可获得优异的匀染性和染色亲和性的匀染剂以及使用了该匀染剂的染色纤维制品的制造方法。本发明提供包含规定的成分(A)、成分(B)和成分(C)的匀染剂以及使用了该匀染剂的染色纤维制品的制造方法。

Description

匀染剂和染色纤维制品的制造方法 技术领域
本发明涉及对包含聚酯纤维的纤维等进行染色时使用的匀染剂和通过使用了该匀染剂的染色得到的染色纤维制品的制造方法。
背景技术
一般地，在高温和高压的条件下花费时间进行对纤维的染色。例如，如下所述进行对聚酯纤维的染色。首先，将处理浴加热到约40～60℃，通常花费约50～80分钟(想要迅速地完成染色的情形下花费约30～50分钟)慢慢地升温，在120～135℃(通常约130℃)进行约30～90分钟(通常约60分钟)的高温高压处理。
为了减少能量和作业时间，一直以来希望缩短染色时间、即提高升温速度，但如果提高升温速度，则存在容易产生染斑、难以获得充分的染色亲和性(dyeing affinity)的问题。特别地，使用分散性低的染料或多种染料的情况下，染色对象包含混纺纤维或极细纤维的情形下容易产生染斑。
然而，在染色处理液中添加用于防止染料的凝聚、无斑地均匀染色的匀染剂和根据需要用于浓浓地染色的导染剂。据认为利用这样的匀染剂或导染剂解决与升温速度的高速化相伴的上述问题，作为匀染剂或导染剂，目前为止公开了以下的技术。
作为匀染剂，例如，专利文献1中公开了聚酯纤维用匀染剂，其以规定的量含有选自苯甲酸酯和二苄基醚的1种或2种以上、聚亚烷基二醇脂肪酸二酯、和对于苯乙烯化苯酚或α-甲基苯乙烯化苯酚的碳原子数2～4的氧化烯加成物的硫酸酯盐或磷酸酯盐。作为导染剂，专利文献2中公开了包含苯甲酸酯和非离子活性剂的导染剂。

发明内容
发明要解决的课题
但是，上述以往的匀染剂和导染剂存在染料的分散性不足、容易污染设备的问题。此外，由于匀染剂和导染剂放出特殊气味、作业环境变差，因此存在气味在得到的染色纤维制品中残留的问题。
因此，希望有染料分散性优异、气味小、并且即使在与通常相比升温速度快的情形下也可获得优异的匀染性和染色亲和性的染色纤维制品的匀染剂。
本发明是鉴于上述现有技术具有的课题而完成的，目的在于提供染料分散性优异、气味小、并且即使在与通常相比升温速度快的情形下也能够制造优异的匀染性和染色亲和性的染色纤维制品的匀染剂以及通过使用了该匀染剂的染色制造的染色纤维制品的制造方法。
