Description

A kind of towel tea dyeing technique

Technical field

The present invention relates to a kind of novel dyeing, refer in particular to a kind of tea dyeing technique of towel.

Background technology

Along with improving constantly of living standards of the people, the particularly progressively enhancing of environmental protection consciousness, consumers in general to the requirement of textiles not in variation that just is confined to pattern and noveltyization, and strict more to the inherent quality requirement of product, particularly the environmental protection of product and the requirement of health care are constantly increased especially

At home and abroad on the market, high-grade, novel, organize changeable towel series along with the technology of loom improves, can produce any colored shape, these towels are the variation of tissue flower shape just, also have some to handle and reach effect antibiotic, deodorization by chemical assistant, but by the result of market survey, domestic still do not have by reaching effect antibacterial, deodorization after the natural materials processing.

Summary of the invention

At, the present deficiency of domestic market, the applicant develops a kind of " tea dyes product ", has the effect of natural bacteriostatic health care, specifically: the focusing on of this tea dyeing technique:

A kind of towel tea dyeing technique, this technology includes following steps:

One, pre-treatment

Tea is dyed pretreating reagent 10% and caustic soda 2% mixing, add in the entry, grey cloth is handled, its treatment step is:

(1) pretreating reagent is mixed with caustic soda, add in the entry, form mixed liquor, put into dyeing machine, regulate 80-90 ℃ of temperature, the time is 30 minutes, makes pH value between 11～12;

(2) under the condition of room temperature, grey cloth and mixed liquor are carried out pre-treatment in 1: 18 mass ratio adding dyeing machine, the time is 30 minutes;

(3) under the condition of room temperature, to the washing of the grey cloth after the above-mentioned steps 10 minutes;

(4) at room temperature, grey cloth is carried out processed;

Two, dyeing course

Under the condition of room temperature, 1% catechin and citric acid are mixed, form mixed liquor, grey cloth to be handled, its treatment step is:

(1) temperature is controlled in 40 ℃, adds citric acid earlier, adds catechin again; Make pH value between 3～4;

(2) with grey cloth and mixed liquor under 1: 18 mass ratio, immerse in the dyeing fuel and dye, the time is 20 minutes;

(3) under the condition of room temperature, the grey cloth after the above-mentioned steps was washed 10 minutes;

Three, acid treatment

(1) temperature is controlled at 50～60 ℃, and in the citric acid adding dyeing installation with 2g/L, pH value is controlled between 3～4, grey cloth is carried out 10 minutes acid treatment;

(2) under the condition of room temperature, the grey cloth after the above-mentioned steps was washed 10 minutes;

Four, the softening processing

Temperature is controlled at 40 ℃, adds softener, soaks 20 minutes;

The beneficial effect of the tea dyeing technique of above-mentioned towel is: this tea dyes the catechin that product uses and is the extracted form natural plant product, and the back health that dyes is very strong, and human body is not had injury, and Se Laodu is strong, and is soft naturally, bacteriostasis and health-care, and have the delicate fragrance of tea, natural environmental protection.

Fig. 1 is a process chart of the present invention.

The specific embodiment

For making your auditor know major technique content of the present invention, and embodiment, be described as follows with embodiment now: see also accompanying drawing 1, it is a process chart of the present invention.

Rapidoprint of the present invention is: cotton towel;

Raw material of the present invention is: pretreating reagent, caustic soda, catechin, citric acid;

The technical equipment that adopts:

One, fabric manufacture equipment: revive and longevity G6200 Rapier looms.This equipment is that performance is the most stable in the world, function is the most complete, the state-of-the-art towel class of class loom corollary equipment.

Two, pre-treatment and dyeing installation: the overflow dyeing machine that the upright letter company in Hong Kong produces, this equipment good seal performance, plant capacity is big, and automaticity is than higher, and water circulation is abundant, and can the every technological parameter of flexible modulation in pre-treatment and dyeing course.

Three, dehydration equipment: the Water Extraction Machinery that Guangdong grace is produced with combination plant company, this Water Extraction Machinery are gone into out the cloth equipment rationally, and friction level is little, the dewatering efficiency height.

Four, drying plant: loose formula dryer, the hot impulse force of this equipment characteristic is big, and grey cloth is inside beaten fully, and looped pile is fluffy effective.

Before carrying out concrete technological process, need be with the grey cloth destarch, because towel needs yarn is carried out starching in woven process, slurry is mainly with wheaten starch latitude master, in order to make grey cloth destarch cloth before dyeing clean, uneven dyeing easily, and tinctorial yield is low, and for this reason, the grey cloth destarch is extremely important, we have adopted best desizing agent, so that reach extraordinary effect.

In addition because colouring agent catechin of the present invention is macromolecular particle, on cause that easily look is stained with and the look flower when dying, must be evenly after therefore requiring grey cloth to scouring and bleaching, the applicant has adopted the special technology of scouringing and bleaching to reach best effect.

Its concrete manufacture method is exemplified below, the heavy 250kg of its raw material thing, and shared water 4500l:

This technology includes following steps:

One, pre-treatment

Tea is dyed pretreating reagent 10% and caustic soda 2% mixing, add in the entry, grey cloth is handled, its treatment step is:

(2) under the condition of room temperature, grey cloth and mixed liquor are carried out pre-treatment in 1: 18 mass ratio adding dyeing machine, the time is 30 minutes;

(3) under the condition of room temperature, to the washing of the grey cloth after the above-mentioned steps 10 minutes;

(4) at room temperature, grey cloth is carried out processed;

Two, dyeing course

Under the condition of room temperature, 1% catechin and citric acid are mixed, form mixed liquor, grey cloth to be handled, its treatment step is:

(1) temperature is controlled in 40 ℃, adds citric acid earlier, adds catechin again; Make pH value between 3～4;

(2) with grey cloth and mixed liquor under 1: 18 mass ratio, immerse in the dyeing fuel and dye, the time is 20 minutes;

(3) under the condition of room temperature, the grey cloth after the above-mentioned steps was washed 10 minutes;

Three, acid treatment

(1) temperature is controlled at 50～60 ℃, and in the citric acid adding dyeing installation with 2g/L, pH value is controlled between 3～4, grey cloth is carried out 10 minutes acid treatment;

(2) under the condition of room temperature, the grey cloth after the above-mentioned steps was washed 10 minutes;

Four, the softening processing

Temperature is controlled at 40 ℃, adds softener, soaks 20 minutes.
