Description
Technical field
The invention belongs to cellulose dyeing field, the specially natural tea method that is used for cellulose dyeing,
It is related to a kind of method that tea polyphenols are used for cellulose dyeing.
Background technique
Currently, the domestic dyestuff for textile industry is almost all synthetic dyestuffs, side effect is big, and it is strong to be unfavorable for human body
Health.With the rapid development of our country's economy, people's health consciousness gradually increases, and the use of synthetic dyestuffs can gradually be prohibited, and turns
And develop and use the natural dye of safe and high quality.Pigment rich in tealeaves can be used for natural plant dye dyeing, and
China is the native place of tealeaves, is abounded in tea.The byproduct generated during low-grade tea and tea processing is used for mentioning for Tea Pigment
Take, not only can rational exploitation and utilization natural resources, improve the economic value of tealeaves itself, and can get serial Tea Pigment for contaminating
Color widens pigment market, meets the growing demand to natural pigment of the people.Tea Pigment extraction preparation method is simple, at
This is cheap, and bright in colour, stability is good, is before one kind has development containing there are many effective bioactive substances especially in tealeaves
The natural pigment on way.
This project is intended to study a kind of effective ways that tea comprehensive processing utilizes, first with dark brown in solvent extraction tealeaves
Element, the pigment that then extraction is obtained are used for the dyeing of fiber, not only increase value-added content of product, while realizing garment surface
Pure naturalization of material, meets requirement of the new century people to clothes, is develop " biological garments " " complete green clothes " textile one
A good Research approach.Therefore, to tealeaves pigment for viscose fiber staining research be one be beneficial to ecological environment and
The project of mankind's dress ornament health.
Summary of the invention
In order to solve deficiency in the prior art, the present invention provides the sides that a kind of tea polyphenols are used for cellulose dyeing
Method.
A kind of method that tea polyphenols are used for cellulose dyeing, it is characterised in that the following steps are included:
A. the selection of tealeaves is green tea or leafiness, and pigment composition ratio is regulated and controled by oxidizing process, later by the tealeaves in tealeaves
Pigment extracts, and mainly detects each primary pigments ingredient by ultraviolet specrophotometer during extracting tea polyphenols and contains
Amount, and effective content >=80% of tea polyphenols；
B. tealeaves pigment obtained in step a is mixed with fiber；
C. the temperature of the fiber with tealeaves pigment in step b is controlled in room temperature, is then dyed, dyeing time control
At 1-3 hours；
D. the fiber after dyeing in step c is soaped；Time of soaping continues 20-40 minutes；
E. the fiber after cup is soaped in step d is washed, washing time continues 10-15 minutes；
F. the fiber after being washed in step e is dried；
G. fiber obtained in step f is subjected to performance detection, is scrapped if unqualified, if qualified packing and binding.
The detailed step of the step a are as follows: tealeaves is crushed, pigment is added into smashed tealeaves mixture and mentions
It takes solvent to carry out pigment extraction, then mixed liquor is filtered, obtained tealeaves is concentrated, is dried to obtain Tea color
Element.
The pigment Extraction solvent are as follows: dehydrated alcohol.
It is described to tealeaves carry out concentration refer to being concentrated in vacuo.
The range for the room temperature mentioned in the step c is 50-120 DEG C.
Optimum temperature range is 80-90 DEG C in the step c.
Temperature of soaping in the step d is 50-60 DEG C.
Drying in the step f refers to carrying out hot drying using dryer.
Performance detection in the step g includes: color fastness, light fastness and the performance detection of perspiration fastness.
Beneficial effects of the present invention:
1. since coloured pigments of the present invention are what tealeaves extracted, so the fiber that the present invention dyes is very environmentally friendly, it is real
Pure naturalization of garment material is showed.
2. since coloured pigments of the present invention are what tealeaves extracted, so dyeing the clothes come using the present invention
Skin-safe of the fabric to human body.
3. the present invention dyes the comfort that the garment material come increases clothes.
4. since coloured pigments of the present invention are what tealeaves extracted, and Tea Pigment extraction preparation method is simple,
Low in cost, bright in colour, stability is good, so the present invention dyes the fiber come and increases dyeing compared with the prior art
Efficiency reduces the cost of dyeing.
