Description
Technical field
The present invention relates to a kind of dyeing processing technique of acid fiber by polylactic Woven Fabrics, belong to the dyeing technical field of textiles.
Background technology
Acid fiber by polylactic (polylactic acid, be called for short PLA) be with starch-containing materials such as corn, wheats, be converted into lactic acid through fermentation, the fiber of making through polymerization, spinning again, it not only has excellent physical property and takes performance, and the energy biodegradation, be a kind of novel environment friendly fiber of Natural Circulation fully, also be present unique synthetic fiber that do not rely on petroleum resources.
The PLA fiber has unique physical and chemical performance, with soft, the form stable of its garment material of making, has good crimpiness and elasticity.But the PLA fiber is acidproof not alkaline-resisting and fusing point is low, therefore to PLA can not handle with highly basic, dyeing temperature can not be high.This especially processes with the dyeing and finishing of blended yarn woven fabrics such as cotton, bamboo PLA the PLA lining and has brought difficulty.
At present, PLA existing preliminary research in dyeing processing.Patent related to the present invention has: CN1558023 has invented the PLA fiber dyeing method, carries out the dyeing innovation at the PLA fiber properties; CN1776086 dyes at pure PLA fiber, and this technology replaces water to dye as dyeing medium by pressure at 10 to 30Mpa supercritical carbon dioxide fluids; CN101082153 uses DISPERSE DYES to dye at the PLA knitted cloth; CN101270551 be at DISPERSE DYES to the low problem of PLA fiber dye-uptake, make dyeing promoter with DISPERSE DYES.
Above-mentioned prior art all is the dyeing at PLA fiber or its knitted cloth, but less to the Study on dyeing of PLA fabric especially woven and blended cloth thereof.Though CN101082154 has related to PLA fiber/cotton blending tatting dyeing, but because the dye bath ratio that relates to is unfavorable for environmental protection more greatly, and heating up is controlled at 0.5 ℃/min, and this is difficult to accomplish in the operation of actual factory, has also that energy consumption is big, practical operation is than problems such as difficulties.
Summary of the invention
The object of the present invention is to provide a kind of technological design reasonable, easy and simple to handle, can effectively reduce the dyeing processing technique of the acid fiber by polylactic Woven Fabrics of auxiliary dosage and environmental pollution.
The present invention is the dyeing processing technique of acid fiber by polylactic Woven Fabrics, after in overflow dyeing machine, putting into the pure PLA fiber shuttle-woven cloth or PLA fiber/cotton blending Woven Fabrics after pre-treatment is finished, put into the dye liquor that has prepared DISPERSE DYES and auxiliary agent at normal temperatures successively, directly be warming up to 70 ± 5 ℃, it is characterized in that the heating rate that continues with 1～2 ℃/min is raised to 85-95 ℃, insulation 5～10min; If dye middle light color, then continue to be raised to 95～105 ℃ insulation 30～45min with 1～2 ℃/min heating rate; If dye dark color, then the heating rate with 1～2 ℃/min is raised to 110～120 ℃, cools to 60～70 ℃ behind insulation 45～60min and soaps.
Described PLA fiber/cotton blending Woven Fabrics also can continue to add REACTIVE DYES since 40 ± 5 ℃; bath raio 1: 25～30; behind insulation 30 ± 5min; add glauber salt insulation 40 ± 5min; with 1～2 ℃/min heating rate to 60 ℃ adding soda ash, be cooled to the normal temperature washing behind insulation 30 ± 5min then.
The bath raio that has prepared the dye liquor of DISPERSE DYES and auxiliary agent under the described normal temperature can be 1: 10～and 15, PH is 4～6.
Described DISPERSE DYES can be the low form DISPERSE DYES, comprises following any: DianixAC-E series, and Dianix XF series, dragon is contained UN-SE series.
Described auxiliary agent can comprise penetrating agent JFC and dispersant NNO etc.
Light color can comprise cream-coloured, orange, light blue, pink colour etc. in described, and that dark color comprises is dark blue, black, dark brown etc.
The present invention compared with prior art has following outstanding advantage and good effect:
1, according to the characteristic of PLA fiber, through repetition test repeatedly, rationally determined dyeing temperature and heating rate, the Woven Fabrics to different depths such as light color in dying or dark colors adopts different dyeing temperatures simultaneously.In when light color in dying, the dyeing maximum temperature is 95～105 ℃ and is incubated 30～45min, both prevented that PLA fiber Yin Wendu is too high and loss is powerful, saved the energy again.When dying dark color, the dyeing maximum temperature is 110～120 ℃ ℃ and is incubated 45～60min, cools to 60 ℃ then and soaps, and has guaranteed dye-uptake and dyefastness.
2, because PLA fibrous glass temperature and softening point temperature are lower, the present invention is through repeatedly repetition test comparison, rationally select the DISPERSE DYES of low form for use, and definite dye bath ratio is 1: 10～15, PH is 4～6, compare at 1: 20 with existing dyeing bath raio, both had good Color, saved the energy and the pollution that has reduced environment again greatly, can also satisfy the dyeing industrial requirement of pure PLA fiber or PLA fiber/cotton blending (interweaving) Woven Fabrics.
3, to PLA fiber/cotton blending (interweaving) Woven Fabrics, dye the PLA fiber by using the low temperature DISPERSE DYES earlier, use REACTIVE DYES resisdye cellulose fibre again, make that its process route has compared with prior art that bath raio is low, power consumption less, dyeing COLOR FASTNESS height, advantage beautiful in colour.
