Abstract
The invention discloses a dyeing processing using reducing and bleeding, which is realized by the following scheme: obtaining semi-finished product of plain white cloth, and working procedures of padding dye solution, steaming, washing, oxidizing, soaping, washing, drying, padding and softening, tentering, shrinking and obtaining a finished product. Another drying working procedure and the working procedure of padding reducing solution are sequentially added between the working procedures of padding dye solution and the steaming; and dye used by the working procedure of padding dye solution is a mixture of reducing dye the weight ratio of which is 2:3-3:2 and sulfur dye. By the invention, the reducing dye with excellent color fastness and sulfur dye which is easy to bleed are mixed and compounded according to a certain proportion to obtain new bleeding and reducing dye; and two kinds of dye can be simultaneously dyed on the cloth cover by adding a reducing agent suitable for the sulfur dye in a reducing solution prescription and using a one-step dyeing method. Compared with the prior art, clothes made of fabrics dyed by the process can obtain satisfied bleeding, traditional and leisure style after being subject to simple washing with enzyme; and in addition, the light fastness in the medium-light colors can reach 3-4 levels.
Description
Technical field
The present invention relates to the textile dyeing and finishing field, specifically is to wash to take off dyeing.
Background technology
Present washing taken off the dyeing continuous knot dyeing technology and mainly contained pigment dyeing technique and sulfur dyeing technology.
The technological process of pigment dyeing technique is: semi-products calico → pad is coated with material process → dyeing process → baking operation → bake operation → pad softening step → tentering operation → shrinking processes → finished product.Characteristics such as pigment dyeing technique has cheap, and chromatogram is complete, but exist dried wet rubbing fastness poor, especially brushing fastness is poor especially, and ready-made clothes can cause local whiting through scrubbing or washing by rubbing with the hands, and light light fastness is relatively poor.Because coating is to cover on the cloth cover by binder film, feel also can be affected, and the fluctuation of setting temperature can cause and wash the back aberration in the production process.
The technological process of sulfur dyeing technology is: semi-products calico → pad dye liquor operation → decatize operation → washing step → oxidation operation → soap washing → washing step → baking operation → pad softening step → tentering operation → shrinking processes → finished product.It is to wash the lining that fades that sulfur dyeing technology is fit to dark in the processing, and chromatogram is comparatively complete.But with the middle light photooxidation resistant fastness extreme difference of its production, the cloth cover pH value influence of light of checking colors also is very big, especially khaki, coffee, military green colour system.More fatal shortcoming is that the seriously not anti-chlorine of the product of this explained hereafter floats, and specific activity dyeing is poorer.Dark dried wet rubbing fastness also is very poor.Because dye liquor is the leuco compound dyeing of SULPHUR DYES; Each dyestuff is not of uniform size to cellulosic affinity, to LOT look before washing and the difficult control of Bian Zhongse, causes the LOT look amount of returning something for repairs very big in the production process; Thereby influence the back LOT look of washing of finished product, production efficiency is also lower.
Summary of the invention
The good dyeing process using reducing and bleeding of COLOR FASTNESS that the purpose of this invention is to provide a kind of middle light color.
Technical scheme of the present invention is such: dyeing process using reducing and bleeding, realize through following scheme: semi-products calico → pad dye liquor operation → decatize operation → washing step → oxidation operation → soap washing → washing step → baking operation → pad softening step → tentering operation → shrinking processes → finished product; Above-mentioned padding also passed through another baking operation successively between dye liquor operation and the above-mentioned decatize operation and padded the reducing solution operation; The above-mentioned used dyestuff of dye liquor operation that pads is that weight ratio is 2: 3-3: 2 the reducing dye and the mixture of SULPHUR DYES.
Above-mentioned another baking operation: temperature 60-80 ℃, the time is as the criterion with the cloth cover oven dry.
The above-mentioned reducing solution operation of padding: will pass through cloth after above-mentioned another baking operation is handled and carry out normal temperature and pad reducing solution, and advance steam box then and accomplish second at 100-102 ℃ of decatize 45-60 and dye process; Whenever go up and state reducing solution and be prepared from the sodium hydrosulfite of 10-50 gram, the reductant of 20 grams, the caustic soda and the water of 10-50 gram.
After adopting such scheme; The present invention with the extraordinary reducing dye of each item fastness be prone to wash the SULPHUR DYES that takes off according to a certain percentage (2: 3-3: 2) piece together mix composite; Obtain new using reducing and bleeding dyestuff; With adding a kind of reductant that is fit to this SULPHUR DYES in the reducing solution prescription, these two kinds of dyestuffs are dyed on the cloth cover simultaneously again with the method that once dyes.Compared with prior art, make clothes through the lining of technology dyeing of the present invention and take off imitative old leisure style, and its light at middle light color can reach the 3-4 level after simple leaven washing can obtain gratifying washing.
