Moisture absorption anti-UV fabric one-pass bath method for dyeing technique
Technical field
The invention belongs to the production technical field of functional fabric, and in particular to moisture absorption anti-UV fabric one-pass bath method for dyeing work
Skill.
Background technology
Moisture absorption anti-UV fabric can make human skin keep nice and cool sensation, while require that fabric possesses the texture of softness;Mesh
Before, for moisture absorption anti-UV fabric typically using Alkali reduction, the bath method of dyeing two, the process time is longer, consumes compared with multi-energy, production
Cost is big.Single bath process is primarily present two defects:(1)Disperse dyes are washed without reduction, are adhered on cotton fiber, are caused fastness
It is bad;(2)Dye strength is too high, and the disperse dyes of absorption hinder the absorption of reactive dye and upper dye in cotton dye, cause depth
Degree is inadequate, wastes dyestuff.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide moisture absorption anti-UV fabric one-pass bath method for dyeing technique.
The technical scheme is that:Moisture absorption anti-UV fabric one-pass bath method for dyeing technique, comprises the following steps:
1)Alkali reduction
NaOH is added in water(30%)15g/L, 90~100 DEG C of water temperature, fabric is placed 25~35 minutes in water;Then with 2~
3 DEG C/min of speed, water temperature drop to 35~40 DEG C;
2)Dyeing
Acetic acid is added, pH value is adjusted to 6.0~6.5;
Anti UV finishing agent, high temperature levelling agent are added, even, insulation 5~8 minutes is walked at 35~40 DEG C;Anti UV finishing agent:4
~6g/L, high temperature levelling agent:1~2g/L;
Add disperse dyes;
With 1~2 DEG C/min of speed, water temperature drops to 80 DEG C, is incubated 10 minutes;Again with 1~1.5 DEG C/min of speed, from 80
130 DEG C DEG C are raised to, is incubated 20 minutes;Then 80 DEG C are down to 1.5~2 DEG C/min of speed;
3)Cleaning, reduction cleaner RAS 2g/L are added in clear water;80-85 DEG C of water temperature, minute time 5-10;
4)Soft treatment
Use hydrophilic softener, 60~80 DEG C of water temperature, 15~25 minutes time.
In the present invention, disperse dyes selection, is the existing public technology in this area, does not do special instruction limitation herein.
Beneficial effect:Moisture absorption anti-UV fabric one-pass bath method for dyeing technique provided by the invention, improvement improve the soft of fabric
Soft, smooth, fabric possesses good uvioresistant performance;Processing step has saved energy consumption.
Embodiment
With reference to specific embodiment, the present invention will be further described.
