CN104420364A - Reactive dye cold-pad batch dyeing process for pure cotton fabric - Google Patents

Abstract

The invention discloses a reactive dye cold-pad batch dyeing process for a pure cotton fabric. The process comprises the following steps: preparing dyeing liquor, rolling, batching, yarding and performing fixation, and washing. The problems that before and later color difference, left-center-right color difference, fabric covering black gas, seam mark and shallow edge easily occur in the dyeing production process and the like are solved, and the process is convenient to operate, uniform in coloring and high in color fastness.

Description

Cold Pad

 

Technical field

The invention belongs to a kind of dyeing, be specifically related to a kind of Cold Pad.

 

Background technology

Cold rolling batch-dying process equipment investment is few, and capital cost is low, strong adaptability, and energy consumption is low, and dye utilization rate is high, and pollute few, dyeing product cloth cover effect is good.Full color, fastness to washing, is increasingly used for the production of garment material.But aberration, left, center, right aberration before and after this technique easily occurs in dyeing production process, and the problem such as the black gas of cloth cover, margin to seam print and limit be shallow.

 

Summary of the invention

In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of Cold Pad is provided, improve dyeing fixation rate and product specification.

Cold Pad provided by the invention, step is as follows:

(a) preparation dye liquor: the dye liquor of preparation waterglass 65g/L, caustic soda 13.8g/L, dyestuff 20g/L, material under room temperature, control mixed alkali liquor and dye liquor temperature are in 25 DEG C;

B () rolls material: textile dyeing, is adjusted to minimum by the nip pressure of padding machine, middle oil pressure 1.8kg, both sides air pressure 1.2kg, speed of a motor vehicle 40m/min, ensures that pick-up is more than 65%, groove dye liquor temperature 20 ~ 25 DEG C;

C () clot: fabric is rolled onto rapidly on glass bar after going out padding machine, closely wraps up with plastic sheeting, hangs in an oven;

D () banks up fixation: fabric is banked up fixation, rotating speed 8 ~ 10r/min, and temperature of banking up should higher than groove temperature 22 ~ 27 DEG C, and keep environment temperature 20 ~ 40 DEG C, bank up 12 ~ 14h;

E () washes: use clean water fabric.

Cold Pad provided by the invention, its beneficial effect is, avoids and easily occur front and back aberration, left, center, right aberration in dyeing production process, and the black gas of cloth cover, margin to seam print and the problem such as limit is shallow, easy to operate, evenly, COLOR FASTNESS is good in colouring.

 

Detailed description of the invention

Below in conjunction with an embodiment, be described in detail provided by the invention.
