Abstract

The present application relates to dyeing and finishing auxiliaries and process field, disclose a kind of preparation and its application process of open agent for cellulose fiber and polyester interwoven fabric, comprising the following steps: (1) open agent preparation;(2) open agent same dispersion dye same bath open agent dyeing polyester;(3) active dyeing cellulose fiber;(4) enzyme washing and softening, fixed baking and beating.The present application has the following advantages and effects: the open agent can be added together with the dispersion dye, realizing open agent and dyeing same bath, this same bath process not only helps fiber to obtain good hand feeling and use performance, reduces the damage of fiber strength, but also can effectively remove the starch slurry on fabric, simplifies fabric pretreatment process, shortens process flow and time, reduces production cost, can alleviate the safety and cost problems brought by traditional concentrated sulfuric acid open agent, dyeing two bath method.
