Abstract

The invention relates to the field of textile fabric production and dyeing, in particular to a one-step-one-bath dyeing technology for DTY/FDY (draw textured yarn/fully drawn yarn) and CDP (cationic dyeable polyester) blended fabric. The technology comprises the steps as follows: fabric is added in water firstly, and a bath ratio is 1: 8; then after the temperature is increased to 40 DEG C, a dispersing and leveling agent, a disperse dye, an anti-settling agent MS and a cationic dye are sequentially added, and the PH (potential of hydrogen) value is regulated by a glacial acetic acid to 4; the temperature is directly increased to 60 DEG C, heat preservation is performed for 10 minutes, the heat preservation is performed for 10 minutes after the temperature is increased to 100 DEG C at a speed of increasing 2 DEG C per minute, the heat preservation is performed for 30 minutes after the temperature is increased to 125 DEG C at a speed of increasing 1 DEG C per minute, and the temperature is decreased to 80 DEG C at a speed of decreasing 1 DEG C per minute; and finally washing is performed. With the adoption of the one-step-one-bath dyeing technology for DTY/FDY and CDP blended fabric, the precipitation phenomenon caused by combination of different dyes can be effectively prevented, simultaneously, color lumps and color spots after dyeing can be effectively prevented, the energy consumption is effectively reduced, the dyeing time is effectively shortened, the dyeing cost is reduced, and the economic benefit is increased.

Description

One step One Bath Dyeing Process of DTY/FDY and CDP blended yarn woven fabric

Technical field

The present invention relates to weaving face fabric production dyeing field, a step One Bath Dyeing Process of especially a kind of DTY/FDY and CDP blended yarn woven fabric.

Background technology

The dyeing of DTY/FDY and CDP blended yarn woven fabric for a long time, because the dyeing environment of two kinds of fibers is contradictory, adopt traditional technique two step two-bath process that adopt to carry out, but time consumption and energy consumption is large more, and cost is high.DTY/FDY belongs to routine and washs yarn, and under acid condition, with dying in DISPERSE DYES, and CDP fiber belongs to Cationic Dyeable Pet, can only adopt cation dyes, and cation dyes are with positive charge, as dyeed together, dye precipitated easily occur, cause dyeing color spot, look stain.

Summary of the invention

The object of the invention is provides a kind of energy consumption that can reduce in order to solve the deficiency of above-mentioned technology, shortens the DTY/FDY of dyeing time and a step One Bath Dyeing Process of CDP blended yarn woven fabric.

In order to achieve the above object, one step One Bath Dyeing Process of the DTY/FDY that the present invention is designed and CDP blended yarn woven fabric, first in water, add fabric, bath raio is 1:8, then after being warming up to 40 ℃, add after Disperse Leveler, be incubated 10 minutes, add again after DISPERSE DYES, be incubated 10 minutes, add again after anti-deep dose of MS, be incubated 10 minutes, add again after cation dyes, be incubated 10 minutes, re-using glacial acetic acid regulates pH value to 4-4.5, then after being incubated 10 minutes, be directly warming up to 60 ℃, be incubated 10 minutes, after being warming up to 100 ℃ with the speed of 2 ℃ of raising for 1 minute again, be incubated 10 minutes, after being warming up to 125-130 ℃ with the speed of 1 ℃ of raising for 1 minute again, be incubated 30-45 minute, within 1 minute, to reduce the speed of 1 ℃, be cooled to 80 ℃ again, finally wash, wherein: the addition of Disperse Leveler is 1% of fabric weight, the addition of DISPERSE DYES is 2% of fabric weight, and the addition of anti-deep dose of MS is 1% of fabric weight, and the addition of cation dyes is 1.5% of fabric weight.

As optimization, the speed that adds of Disperse Leveler is to add in 10 minutes; The speed that adds of DISPERSE DYES is to add in 20 minutes; The speed that adds of anti-deep dose of MS is to add in 15 minutes; The speed that adds of cation dyes is to add in 20 minutes; The speed that adds of glacial acetic acid is to add in 15 minutes.

One step One Bath Dyeing Process of the resulting DTY/FDY of the present invention and CDP blended yarn woven fabric, can effectively prevent that different dyes from occurring in conjunction with the phenomenon that produces precipitation, can effectively avoid the color lump color spot producing after dyeing simultaneously, and effectively reduce energy consumption and dyeing time, reduce dyeing cost, improved economic benefit.

According to test: conventional two bath process, every fabric 9-10 hour consuming time, and the present invention 6-7 hour consuming time has saved for about 1/3rd time, and also every fabric of energy consumption such as water, electricity, vapour can reduce about 1/3rd.
