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

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

Summary of the invention

For defect and deficiency aspect alkaline etching and mechanical shearing, the invention provides a kind of etching processing technology of polar fleece fabric, it can overcome existingly processes the safety issue that exists and the pollution problem to environment by alkaline etching, also can solve that the cost that mechanism's shearing exists is high, fabric design form is single simultaneously, can not chromatography after 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 is carried out to burn-out printing, its processing technology is burn-out printing → oven dry → fixation → wash → soap → washing → dehydration → sizing → packaging, and described concentrator comprises mass percent is 45%～55% etchant, mass percent is 40%～44% dispersion printing gum, DISPERSE DYES that mass percent is 2%～8%, 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 is 110 DEG C～130 DEG C;

Described fixation, temperature is 140 DEG C～150 DEG C and continues 2 min～7min;

Described washing → soap → wash comprises following concrete technology successively: clear water is washed 10min～25 min → add antistain agent with 40 DEG C～80 DEG C 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 DEG C～100 DEG C of temperature, wash 10min～25min → clear water and wash 15min～25min altogether 2 times;

Described sizing, setting temperature is 140 DEG C～150 DEG C, the speed of a motor vehicle 25 m/min～40m/min;

Described burn-out printing is carried out according to common cylinder or PLATE SCREAM PRINTING processing;

Described polar fleece light base is entirely to wash that two brushes singly shake or single brush singly shakes any in polar fleece, adopts polar fleece entirely to wash long filament as raw material, and described in it, polar fleece light base grammes per square metre is more than or equal to 150g/m2;

The dyestuff that described knit fabric chromatography is used is DISPERSE DYES, described DISPERSE DYES is high temperature resistant alkali resistance, it can bear alkaline pH value for being more than or equal to 10, that is the DISPERSE DYES adopting is unlikely to be damaged at higher temperature with under compared with the condition of high PH and cause its chromatography to occur extremely.

Compare with existing alkaline etching or mechanical shearing burnt-out printing process, beneficial effect of the present invention is: it has adopted the mode of stamp etching, etchant is joined in concentrator, in stamp, light base is carried out to etching, thereby efficiently solve safety issue that current alkali etching or dissolving bring and the damage problem to mechanical implement, and can overcome current method poor problem of color emissivity in chromatography processing, technique of the present invention has no adverse effects to color fastness to light, solve the feature of environmental protection problem of waste water the like waste discharge simultaneously and solved the single problem of form that machining aspect exists, in addition, adopt sunk part or the bossing of the fabric of processes of the present invention all can carry out chromatography processing, and every COLOR FASTNESS is all good.
