Description

Sex change terylene textiles environmental protection dyeing and finishing technology

Technical field

The present invention relates to a kind of sex change terylene textiles environmental protection dyeing and finishing technology, belong to textiles technology field.

Background technology

Sex change terylene CDP comes from ordinary polyester and the copolymerization of 3,5-sodiosulfoisophthalic acid forms, and due to adding of Third monomer, molecular structure became relatively loose, soft very closely originally, but intensity is also poor, easily abrades; Sulfonic group is introduced on the other hand in molecular structure, CDP fiber hygroscopicity increases, and can use cationic dyeing, and CDP fiber and Lycra fiber pass through organization design, obtain good elastic effect, be suitable for leisure at home and some non-strenuous exercise dresses.

Summary of the invention

The object of the present invention is to provide a kind of sex change terylene textiles environmental protection dyeing and finishing technology, to carry out environmental protection dyeing and finishing for textiles better.

To achieve these goals, technical scheme of the present invention is as follows:

Sex change terylene textiles environmental protection dyeing and finishing technology, specifically comprises the following steps:

(1) technological process: knitted cloth → washing → front setting → dyeing → oven dry → Final finishing → quality inspection;

Fabric is added in room temperature dye liquor, successively defoamer, levelling agent, vinegar acid and direct dyes is added after running 5min, then 70 DEG C are warming up to the speed of 2 DEG C/min, slow down programming rate and be warming up to 98 DEG C to l DEG C/min, then be warming up to 11O DEG C with the speed of l.5 DEG C/min, insulation dyeing 45min, rear cooling discharge opeing, drip washing, changes water, adds acetic acid and color-fixing agent, then 80 DEG C are warming up to, to lower the temperature discharge opeing after insulation 3Omin, drip washing, changes water, add acetic acid and detergent L-1OO, be warming up to 50 DEG C, washing 3Omin, cooling draining;

Sex change terylene has some oil stains in spray silk, warping, weaving process, also have some micromolecular oligomer, they must be removed fully in washing, to avoid the aberration causing silicone oil and oligomer to cause in follow-up dyeing and finishing processing, but the performance due to sex change terylene is different from normal terylene, must temperature be controlled at 60-80 DEG C in water-washing process, and very large extruding force can not be had to fabrics cloth cover, otherwise the impression that cannot eliminate can be produced, occur that pressure defect place color is inconsistent after dyeing;

Prevent the measure of look flower:

(1) choose reasonable dyestuff: the dyestuff that dyeing rate should be selected more close and compatibility good, for general dacron, three kinds of dyestuff Mixed Pinyins, not easily cause look flower phenomenon, but for sex change terylene extra thin fabric, different dyestuffs to be selected according to the dyeing depth, during general dye light color, dye dosage is few, low form dyestuff should be adopted, low form dye molecule is little, be diffused into fibrous inside to be easier to, namely dyeing speed is fast, should control to heat up slowly, and during dye dark color, dye dosage is large, high temperature modification dyestuff should be selected, high temperature modification dye molecule is large, be diffused into fibrous inside more difficult, namely dyeing speed is slow, so, controlling programming rate should be hurry up, but temperature retention time sufficiently,

(2) rationally effective levelling agent and healant is selected: answer Selection effect cloudy, nonionic levelling agent preferably, effectively can suppress the dyestuff sharply upper dye because the reason such as too fast that heats up causes, play slow dye effect, avoid look flower, in addition, if one and produce look flower, suitable terylene healant can be selected, grey cloth is repaired, re-uses, larger waste can not be caused;

(3) strengthen dye bath ratio, general bath raio about 1:20 to 1:25 is best, and increase bath raio can improve grey cloth liquid carrying rate, makes the even fully upper dye effectively of dyestuff in fiber, thus avoids generation look to spend;

Prevent scratch:

(1) dyeing installation type selecting: answer first-selected beam dyeing machine, the fabric of this dyeing machine is motionless, and dye liquor circulates from inside to outside and dyestuff is evenly contaminated effectively in fiber, prevents fabric from tiing a knot, abrades;

(2), before and after piece dyeing finishing in transportation, necessarily use plastic bag packaging, avoid it to abrade with the not only sliding surface contacted;

(3) any position contacted with grey cloth in staining jar all will polish smooth;

(4) strengthen dye bath ratio, improve grey cloth liquid carrying rate, thus reduce grey cloth scratch;

(5) dyeing time strengthen wetting softener: due in dyeing course grey cloth run time, mutual extruding, collision, particularly arrive high temperature 110 DEG C, fiber undergoes rapid expansion, be easily mutually wound around, thus produce scratch, add wetting softener, can effectively avoid this phenomenon, but will note, necessarily add the moon, nonionic, otherwise can water absorption of fabrics be affected.

Of the present inventionly profitablely to be: the design of the no matter loose or narrow body of sex change polyester color fabric prepared by the present invention, comfortable nature, does not have wrinkle, also can not be too loose, and perfect fit, fully demonstrate simple aesthetic feeling, moment enjoyment next to the skin, technique environmental protection, has better benefit.

Detailed description of the invention

Below in conjunction with embodiment, the specific embodiment of the present invention is described, better to understand the present invention.
