Abstract

The invention relates to a dyeing technology for polylactic acid/richcel/bamboo fiber blended fabric employing a dispersing/active one-bath process. The technology employs the disperse/active one-bath process to dye the polylactic acid/richcel/bamboo fiber blended fabric, is reduced in dyeing flow and shortened in dyeing time, employs mild dyeing and bath conditions, and helps to mitigate damage to polylactic acid fiber and mitigate environmental pollution.

Description

A kind of PLA/Li Sai/bamboo fiber blended fabric dispersion/Reactive Dyestuffs in One Bath dyeing
Technical field
The present invention relates to field of textiles, be specifically related to a kind of PLA/Li Sai/bamboo fiber blended fabric dispersion/Reactive Dyestuffs in One Bath dyeing.
Background technology
PLA/Li Sai/bamboo fiber blended fabric be by acid fiber by polylactic, Li Sai and bamboo fibre according to 4/4/2 ratio blending form.Textile fabric mainly divides three classes according to raw material sources: one is the fiber deriving from plant resources, as cotton, fiber crops, Li Sai, viscose and bamboo fibre etc.; Two is the fibers deriving from Animal resources, as wool, silk etc.; Three is the fibers deriving from petroleum resources, as terylene, polyamide fibre, eyeball synthetic fibre etc.Divide from raw material sources, acid fiber by polylactic, Li Sai, bamboo fibre belong to the fiber deriving from plant resources.At present, the polyster fibre deriving from petroleum resources and the cotton fiber deriving from plant resources occupy the front two of textile fabric consumption always.Because petroleum resources are day by day exhausted, therefore pay attention to the application of natural fabric and adopt natural resources to prepare tencel fabric and received unprecedented attention.
PLA/Li Sai/bamboo fiber blended fabric makes PLA, Li Sai and bamboo fibre maximize favourable factors and minimize unfavourable ones, make full use of the advantage of various fiber, obtain the fabric having several fiber advantage concurrently, solve acid fiber by polylactic hygroscopicity difference and the easy problem playing electrostatic, reduce the cost of weaving face fabric, give this BLENDED FABRIC wearing comfort and biological degradability, and this fabric have antibacterial, ultraviolet radiation absorption good, the function such as durability and shrink resistance.
Compared with Single Fiber textiles, the dyeing and finishing difficulty of processing of multicomponent fibre textiles is comparatively large, the dyeing of current multicomponent fibre textiles oneself become one of successful key factor of restriction dyeing and printing process enterprise.Because acid fiber by polylactic is not alkaline-resisting, more responsive to temperature, and DISPERSE DYES is generally lower at polylactic acid fiber fabrics dye uptake, makes acid fiber by polylactic BLENDED FABRIC dyeing and finishing difficulty of processing larger; Traditional dyeing and finishing technology long flow path, water, electricity and chemicals consumption are many, and the impact caused environment is large.For this reason, how to improve the dyestuff dye uptake of acid fiber by polylactic, reduce the damage of dyeing and finishing processing to PLA BLENDED FABRIC, reduce the research research direction that dyeing and finishing cost becomes dyeing and finishing technique researcher.
The colouring method long flow path of the PLA/Li Sai/bamboo fiber blended fabric of current employing, the time is long, and chemical substance consumption and water consumption are comparatively large, bring environmental pollution and waste.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to provide a kind of PLA/Li Sai/bamboo fiber blended fabric dispersion/Reactive Dyestuffs in One Bath dyeing.Described technique adopts dispersion/Reactive Dyestuffs in One Bath to knit dyeing to PLA/Li Sai/bamboo fiber blended, decreases dyeing flow, shortens dyeing time, adopt the dye bath condition of gentleness, alleviate the damage to acid fiber by polylactic, alleviate environmental pollution.
The present invention adopts dispersion/Reactive Dyestuffs in One Bath to dye to PLA/Li Sai/bamboo fiber blended fabric, the dispersion being applicable to single bath process, REACTIVE DYES are screened, have studied activity, dispersion and its mixed dye respectively in the upper dye situation of poly-breast/sour beautiful match/bamboo fiber blended fabric, optimize One Bath Dyeing Process.
