Description
Technical field
The invention belongs to cellulose dyeing field, specially natural tea is used for the method for cellulose dyeing,
It is related to a kind of method that natural tea pigment is used for cellulose dyeing.
Background technology
At present, the domestic dyestuff for being used for textile industry is almost all synthetic dyestuffs, and its side effect is big, is unfavorable for human body and is good for
Health.With the fast development of China's economy, gradually enhancing, the use of synthetic dyestuffs can gradually be prohibited people's health consciousness, turn
And develop the natural dye of safe and high quality.Containing abundant pigment among tealeaves, dyed available for natural plant dye, and
China is the native place of tealeaves, is abounded in tea.Caused byproduct during low-grade tea and tea processing is used for carrying for Tea Pigment
Take, not only can rational exploitation and utilization natural resources, improve tealeaves economic value in itself, and serial Tea Pigment can be obtained and be used to contaminate
Color, pigment market is widened, meet the growing demand to natural pigment of the people.Tea Pigment extraction preparation method is simple, into
This is cheap, and bright in colour, stability is good, and a variety of effective bioactive substances are contained especially in tealeaves, are before one kind has development
The natural pigment on way.
This project is intended to study the effective ways that a kind of 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 realize garment surface
Pure naturalization of material, meets requirement of the new century people to clothes, is develop " biological garments " " complete green clothes " textile one
Individual good Research approach.Therefore, to tealeaves pigment be used for viscose fiber staining research be one be beneficial to ecological environment and
The problem of mankind's dress ornament health.
The content of the invention
In order to solve deficiency of the prior art, natural tea pigment is used for cellulose fibre the invention provides one kind
The method of dyeing.
A kind of method that natural tea pigment is used for cellulose dyeing, it is characterised in that comprise the following steps：
A. the tealeaves pigment in tealeaves is extracted；
B. the tealeaves pigment obtained in step a is mixed with beautiful color fiber；
C. then the temperature control of the beautiful color fiber with tealeaves pigment in step b is dyed, dyeing time at normal temperature
Control is in 1-3 hours；
D. the beautiful color fiber after being dyed in step c is soaped；Soap time lasting 20-40 minutes；
E. the beautiful color fiber after cup in step d is soaped is washed, and washing time continues 10-15 minutes；
F. the beautiful color fiber after being washed in step e is dried；
G. the beautiful color fiber obtained in step f is subjected to performance detection, scrapped if unqualified, the packing and binding if qualified.
The detailed step of the step a is：Tealeaves is crushed, adding pigment in the tealeaves mixture toward after crushing carries
Take 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 is：Absolute ethyl alcohol.
It is described concentration is carried out to tealeaves to refer to being concentrated in vacuo.
The scope of the normal temperature mentioned in the step c is 80-130 DEG 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. because coloured pigments of the present invention are tealeaves extraction, so the fiber of the invention that come that dyes is very environmentally friendly, it is real
Pure naturalization of garment material is showed.
2. because coloured pigments of the present invention are tealeaves extraction, so dyeing the clothes come using the present invention
Skin-safe of the fabric to human body.
3. the present invention dyes the comfortableness that the garment material come adds clothes.
4. because coloured pigments of the present invention are tealeaves extraction, and Tea Pigment extraction preparation method is simple,
Cost is cheap, and bright in colour, stability is good, so the present invention dyes the fiber come and adds dyeing compared to prior art
Efficiency, reduce the cost of dyeing.
