Abstract

The invention provides a dyeing process for a piece dyed fabric. The dyeing process comprises a dye liquor padding step, a pre-drying step, and a washing and drying step, and is characterized in that: a color fixing liquid padding normal-temperature rolling and stacking process is increased between the pre-drying step and the washing and drying step, so that the entire process sequentially comprises the dye liquor padding step, the pre-drying step, the color fixing liquid padding normal-temperature rolling and stacking step and the washing and drying step. Since the normal-temperature rolling and stacking step is increased, a dye on the fabric is reacted with an alkaline agent for fixing color in padding liquid under a mild condition; the dying method is low in dye hydrolysis and high in color fixing rate compared with a cold padding batch dyeing method and is high in permeability compared with a two-bath steam dyeing method; the dyeing mode is semi-continuous dyeing, is suitable for dyeing of medium and small-scale multi-variety production and is applicable to both thick and thin fabrics; high utilization ratio of equipment is guaranteed; rolling and stacking are performed at normal temperature, so the dyeing process does not have requirements on processing environments; and the fabric processed by the dyeing process has the advantages of uniform and full cloth cover, high glossiness and smooth and soft handfeel.

Description

The dyeing of piece dyeing lining

Technical field

The invention provides a kind of dyeing of piece dyeing lining, belong to textile technology field.

Background technology

The normal REACTIVE DYES continuous dyeing mode that adopts of current piece dyeing lining generally has two bath steam method, cold pad-batch methods, rolls-dry by the fire-roasting method and short wet steaming, has following shortcoming in daily production:

(1) two bathes steam method, promptly rolls dried-pad steaming process: dye liquor is lacked with fiber contact time, and it is big that dyestuff is subjected to drying room temperature, humidity during oven dry, air quantity influences migration, easily produces in the limit aberration and male and female face and can not improve when vapour steaming colour fixing and can increase the weight of; All right when the decatize case is the packing mouth when rolling steaming, if then it is with liquid measure height to the water seal mouth, the chemical agent loss is big, has increased the sewage disposal burden, and has been subjected to the influence of soup, and the control of aberration is more difficult end to end, is unfavorable for operative employee's control; Fabric through-dyeing after the processing is poor, white core phenomenon is serious.

(2) cold pad-batch method: because dyestuff and strong alkaline agent dye in same body lotion, to reactivity, diffusivity, solubility, compatibility and the alkaline-resisting stability requirement height of dyestuff; The process conditions harshness is waited to dye cloth, dye liquor, environment temperature, mangle temperature, banking up to be controlled at constant temperature 23-25 ℃, need set up independently operation room, and thermostat is installed; Dyestuff and alkaline agent need in time to replenish renewal according to certain ratio in the dyeing course, to the requirement height of equipment; Aberration in the limit, big sample poor reproducibility, margin to seam are in and produce impression in the process of the dyeing and the fixation of banking up and can't overcome, and cause and dye defect rate height, and cloth style is full inadequately evenly.

(3) roll-dry by the fire-roasting method and short wet steaming: long flow path, energy consumption height, because dyestuff and alkaline agent are in same body lotion, the dyestuff hydrolysis is many, the poor stability of dye liquor and fabric only through after of short duration the padding promptly by decatize or drying fast, decatize or temperature, time when dry are big to the degree of fixation influence of dyestuff; In the dyeing course dyestuff and alkaline agent must the liquid level automatic control in same body lotion, constantly evenly replenish, and must high temperature, high humidity, to the requirement height of equipment; Fabric through-dyeing after the processing is poor, white core phenomenon is serious.

Summary of the invention

The purpose of this invention is to provide a kind of dyeing that can overcome above-mentioned dyeing defective, stable processing technology height, workable piece dyeing lining.Its major technology content is:

Comprise and pad dye liquor, preliminary drying oven dry, washing baking operation, it is characterized in that: between preliminary drying oven dry and washing oven dry, set up and padded the fixation liquid normal temperature clot technology of banking up, whole procedure of processing has been followed successively by pad dye liquor, preliminary drying to dry, pad the clot of fixation liquid normal temperature and banks up and wash oven dry.

The dyeing of described piece dyeing lining, padding the clot of fixation liquid normal temperature banks up in the operation, mangle is by caustic soda in the groove, glauber salt, alkalescence bleeding agent and caustic soda stabilizing agent dissolve in water and form, wherein the caustic soda consumption is 5～10g/l, the glauber salt consumption is 200～250g/l, alkalescence bleeding agent consumption is 2～5g/l, the reserve salt consumption is 2～5g/l, the caustic soda stabilizing agent can be a soda ash, the mixture of one or both of waterglass, if adopt soda ash, consumption is 20～40g/l, if adopt waterglass, consumption is 2～5g/l, if adopt the mixture of soda ash and waterglass, both weight ratios are 8-12: 1, amount of mixture is 8～15g/l, be controlled at 60-70%, pad clot and sealing with the speed of a motor vehicle of 50-60m/min then, with 6～8 rev/mins speed uniform rotation 16～24 hours.

The present invention compared with prior art, its advantage is:

1, owing to set up and padded the fixation liquid normal temperature clot operation of banking up, make the alkaline agent that plays tint retention in dyestuff on the lining and the mangle react under the condition that relaxes, this staining method dyestuff hydrolysis is few, the degree of fixation height, loose colour is few, can save the use amount of dyestuff;

2, in operation is banked up in the normal temperature clot, dyestuff can fully penetrate into fabric, and through-dyeing is good, no white core phenomenon, male and female face, aberration end to end, aberration also is effectively controlled in the limit, the degree of fixation height of dyestuff, loose colour is few, and the water in the washing baking operation has been saved in easily washing;

3, can bank up in clot under the normal temperature condition, use flexibly and workable, not need to be provided with special workplace, to the processing environment no requirement (NR), the enterprise that generally possesses dyeing and finishing production capacity all is suitable for;

4, adopt the lining of this PROCESS FOR TREATMENT, cloth style is evenly full, and the high feel of glossiness is smooth submissive; The non-sewing impression produces, and top-quality product rate height, thickness fabric all are suitable for this method and dye;

5, this staining method is a semi continuous dyeing, is applicable to the many kinds dyeing of small batch, the usage ratio of equipment height, and bathe decatizes, roll-dry by the fire-bake and lack wet steaming than two, save decatize or baked operation, low equipment investment.
