Description

A kind of etching processing technology of polar fleece fabric

Technical field

The present invention relates to functional knit fabric technical field, be specially a kind of etching processing technology of polar fleece fabric.

Background technology

On the industry polar fleece product is carried out etching or is referred to as etching and processing generally adopting alkaline etching or mechanical shearing processing dual mode to carry out at present, the alkaline etching mode is owing to using caustic soda and its concentration higher, aspect processing safety, there are larger hidden danger and danger, and fabric can not chromatography after the alkaline etching processing, lacks the flexibility of design; The mode general cost of mechanical shearing is high and form is single, also has restriction aspect the chromatography flexibility in addition.

Summary of the invention

For in defective and deficiency aspect alkaline etching and the mechanical shearing, the invention provides a kind of etching processing technology of polar fleece fabric, it can overcome the existing safety issue that exists by alkaline etching processing and to the pollution problem of environment, also can solve that the cost that mechanism's shearing exists is high, the fabric design form is single simultaneously, can not chromatography after the fabric processing etc. problem.

A kind of polar fleece etching processing technology, it is characterized in that: it adopts concentrator according to the colored type of design the polar fleece face of polar fleece light base to be carried out burn-out printing, its processing technology is burn-out printing → oven dry → fixation → wash → soap → wash → dewater → finalize the design → pack, and described concentrator comprises that mass percent is that 45%～55% etchant, mass percent are that 40%～44% dispersion printing gum, mass percent are 2%～8% DISPERSE DYES, all the other are water.

It is further characterized in that:

Described burn-out printing, its bar magnet pressure 25%～35%, the speed of a motor vehicle is 15 m/min～35m/min;

Described oven dry, temperature are 110 ℃～130 ℃;

Described fixation, temperature are 140 ℃～150 ℃ and continue 2 min～7min;

Described washing → soap → wash comprises following concrete technology successively: clear water is washed 10min～25 min → add antistain agent with 40 ℃～80 ℃ hot water to wash 10min～25min → reduction and wash: add sodium hydrosulfite 2 g/L～4g/L, caustic soda 2 g/L～4g/L, soaping agent concentration 1.5%～2.5%, 80 ℃～100 ℃ of temperature are washed 10min～25min → clear water and are washed altogether 15min～25min 2 times;
