Description

A kind of slub dyeing clean preparation method

Technical field

The present invention relates to woolen dyed field, specifically a kind of slub dyeing clean preparation method.

Background technology

Current global energy is in short supply, ecological deterioration, and people have higher requirement to environmental protection, green, and also more and more concern for the environment pollutes, and focuses on the feature of environmental protection of dress, comfortableness and health.From 1989, since UNEP (united nations environment protection administration) has formulated " cleaner production plan ", cleaner production at home and abroad obtained and has widelyd popularize, and China has also formulated the Law of the People's Republic of China on Promoting Clean Production in 2002.Therefore, how to clean, green production be the emphasis of each enterprises pay attention, the woolen dyed dye of at high temperature boiling of tradition, length consuming time, water consumption, power consumption are larger, certain influence is had to environment, and the pH value regulator glacial acetic acid used during dyeing, formic acid have stronger penetrating odor, have a certain impact to the working environment of workman.

In patent document disclosed in (if publication number is CN101666041A), have and protease is applied to woolen dyed technology openly, wool fibre is improved to dyestuff saturated extent of adsorption although can reach, reduce the features such as waste water and gas discharge, but still have the following disadvantages: one, single Protease Treatment effect is uneven, the damage of wool scale layer base portion is serious, follow-up even dyeing weak effect, and fibre damage is heavier; Two, through the wool fibre that ferment treatment is crossed, its surface texture is destroyed in various degree, dyestuff contaminates to pH value very responsive during dyeing, affects on dyestuff and contaminates uniformity.

Summary of the invention

Technical assignment of the present invention is for above-mentioned the deficiencies in the prior art, provides a kind of slub dyeing clean preparation method.

Technical assignment of the present invention realizes in the following manner: a kind of slub dyeing clean preparation method, is characterized in: comprise the following steps:

A, with compositional liquor, preliminary treatment is carried out to wool fibre

Described compositional liquor is mixed obtained by polyethylene glycol, bio protease, bionic acid and water;

B, be that the regulator solution of pH value carries out dyeing process with bionic acid.

Described bio protease is preferably acid protease.

The preferred following methods of described compositional liquor obtains:

Polyethylene glycol is added to the water uniform stirring, regulates pH value to 5 ~ 6 with bionic acid, after pH value is stable, add bio protease, namely stirring and dissolving is complete obtains compositional liquor;

The weight ratio of polyethylene glycol, bio protease and water is preferably 10 ~ 20:50 ~ 70:1000.

Preprocessing process in steps A can above-mentioned compositional liquor, is completed by known preprocess method, but in order to reach the best preferred following detailed process of pretreating effect:

Calculate than 1:8 ~ 12 by pretreatment baths, get wool fibre 100 parts and compositional liquor 800 ~ 1200 parts;

Compositional liquor is added in dye vat, stir 5 ~ 15 minutes under 25 ~ 35 DEG C of conditions, add wool fibre, open liquid pump running 5 ~ 15 minutes, be warming up to 45 ~ 55 DEG C with 1 ~ 3 DEG C/min, keep running 20 ~ 40 minutes;

Be warming up to 80 ~ 90 DEG C, operate and be cooled to 35 ~ 45 DEG C, discharge opeing by cold water flush after 5 ~ 15 minutes, complete preprocessing process.

The dyeing course of step B completes by known preprocess method, but in order to reach the best preferred following detailed process of pretreating effect:

Weigh 10 ~ 12 parts of bionic acids, become acid regulator by 25 ~ 35 DEG C of water, 100 parts of stirring and dissolving, for subsequent use;

Weigh 3 ~ 7 parts of dyestuffs, be dissolved into dye liquor with 100 parts of water for subsequent use;

800 ~ 1000 parts are added water to the wool fibre processed in step A, be warming up to 25 ~ 35 DEG C, operate 3 ~ 8 minutes, add above-mentioned dye liquor, and be adjusted to pH value 4 ~ 5 with acid regulator, operate 5 ~ 15 minutes, be warming up to 72 ~ 78 DEG C with 1 ~ 2 DEG C/min, keep and operate 20 ~ 30 minutes, being cooled to 40 ~ 50 DEG C;

Rinse well with 20 ~ 30 DEG C of clear water, discharge opeing goes out cylinder, completes dyeing course.

Slub dyeing clean preparation method of the present invention compared with prior art has following outstanding beneficial effect:

(1) polyethylene glycol has swelling action to wool fibre, and the effect of bio protease is the catalyst as peptide chain hydrolysis, the peptide bond (>CO-NH-) in wool is impelled to be hydrolyzed, improve wool surfaces scale layer Small molecular permeability, accelerate dye molecule and enter fast.Technique adopts polyethylene glycol and the composite formation compound protease of bio protease, accelerates wool top layer scale layer treatment effect, promotes dye molecule and enters wool fibre and diffusion effect.Contrast by experiment, adopt this composite biological protein enzyme to carry out preliminary treatment to wool, much more effective than standard biologic protease, the wool surfaces uniform in effect processed, is conducive to dyestuff evenly upper dye, reduce dyeing damage;

(2) bionic acid is adopted to substitute high volatility, penetrating odor is serious, and the glacial acetic acid of production process pH value instability, formic acid are as the regulator solution of pH value, above-mentioned composite biological protein enzyme is coordinated to use, ensureing that pH value obtains stability contorting, the while that upper dye being uniform, realize non-volatile penetrating odor, sewage disposal difficulty reduces greatly, realize the features such as cleaner production;

(3) dyeing temperature and dyeing time are significantly reduced.
