Abstract
The invention discloses a method for dyeing a cotton fabric with tea dye and finishing liquor used by the method. The method comprises the following process steps of (1) crushing tea leaves, and adding clean water to extract the tea dye; (2) preparing the finishing liquor from the following materials in parts by weight: 1-5 parts of chitosan powder, 20-25 parts of a glacial acetic acid solution with the concentration being 4%, and 1000 parts of water, namely firstly adding the glacial acetic acid solution with the concentration being 4% into the chitosan powder gradually, simultaneously stirring uniformly, adding water, and mixing uniformly to obtain the finishing liquor; (3) finishing the cotton fabric with the finishing liquor in an immersing and rolling method; and (4) dyeing the cotton fabric finished by the finishing liquor. The method disclosed by the invention has the advantages that not only can the dyeing depth and fastness of the dyed cotton fabric be improved, but also the antibacterial effect and the clean and environment-friendly effects can be achieved.
Description
Technical field
The present invention relates to a kind of method of tea dyes COTTON FABRIC and the dressing liquid used thereof, belong to the textile dyeing technical field.
Background technology
At present, the tea dyestuff is a kind of natural dye, the physiological activator Tea Polyphenols that it is rich in, and content accounts for 20 one 35% of its dry weight, and its main component catechin is easily oxidized, has the free radical of removing, anti-oxidant, anti-sudden change, the function such as antibiotic, antiviral.
China produces tea big country, but due to the spring tea price far above the summer autumn tea, there will be the tea grower to pluck the poor phenomenon of enthusiasm to the summer autumn tea, therefore this part tea resource remains fully to be exploited.And exploitation natural health environmental protection, pseudo-classic grace, there is the tea dyed cotton fabric of antibacterial functions, economic and social benefit is preferably arranged.
When the tea dyes is cotton due to dyestuff and cotton affinity less, cause dying to such an extent that color is not dark, dyefastness is bad, and its color coloured light in different acid-alkali mediums can change a lot.For overcoming above-mentioned shortcoming, the researcher adopts mordant to process tea dyeing fabric, has improved dye level and the dyefastness of tea dyestuff.Mordant commonly used is mantoquita, aluminium salt, rare earth etc.Although utilize the mordant dyeing effect of metal ion can improve color depth and fastness, disagree with the theory of utilizing natural dye to produce Green Textiles.Shitosan, from natural, not only can be realized the environmental protection of whole technical process with him as finishing agent, improves dye level and the fastness of tea dyestuff, and, because itself just has antibacterial action, has strengthened the antibacterial effect of fabric after dyeing.Carry out tea dyeing after utilizing the chitosan finishing pure cotton fabric, dyefastness is good again, and the fabric tinctorial yield is high, and washability and rub resistance are good, even dyeing, reappearance is strong, can utilize existing equipment to realize dyeing, do not increase equipment, do not increase cost, wide market prospects are arranged.
Summary of the invention
Technical problem of the present invention is the defect that overcomes prior art, and a kind of method of tea dyes COTTON FABRIC is provided, and this method not only can improve dye level and the fastness of the COTTON FABRIC after dyeing, and has antibacterial effect, clean environment firendly.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of method of tea dyes COTTON FABRIC, and its processing step is as follows:
1) tealeaves is pulverized, added clear water and extract the tea dyestuff;
2) prepare dressing liquid:
According to following component and component weight portion, get the raw materials ready: chitosan powder: 1-5 part; The glacial acetic acid solution that concentration is 4%: 20-25 part; Water: 1000 parts, the glacial acetic acid solution that is first 4% by concentration adds in chitosan powder gradually, after stirring simultaneously, adds water and mixes well and obtain dressing liquid;
3) utilize dressing liquid to adopt padding method to be arranged COTTON FABRIC;
4) COTTON FABRIC after dressing liquid arranges is dyeed.
Further, in described step 1), during extraction, extraction temperature is controlled at 95 ℃, and extraction time is controlled at 0.5h-1h, keeps tea quality in leaching process: the clear water volume equals needed tea dye strength, during supplement clear water to keep total liquid measure constant; Wherein, the unit of tea quality is gram, and the unit of clear water volume is for rising.
Further, in described step 3), by COTTON FABRIC padding finishing liquid, two soak two roll after, dry 3 min under the environment temperature of 65 ℃.
Further, in described step 4), the bath raio of tea dyeing is 1:20 ~ 50, and the pH value of dye bath is 6 ~ 8, and the dye bath temperature is 40 ℃ ~ 80 ℃, and dyeing time is controlled at 0.5h ~ 1.5h.
Further, described tea dyestuff contains the pigment composition Tea Polyphenols more than 30%.
Further, described COTTON FABRIC is pure cotton woven fabric or pure cotton knitted fabric.
The present invention also provides the dressing liquid used in a kind of method of tea dyes COTTON FABRIC, and its component and each component mass fraction are as follows:
Chitosan powder: 1-5 part;
The glacial acetic acid solution that concentration is 4%: 20-25 part;
Water: 1000 parts.
After having adopted technique scheme, the present invention has following beneficial effect:
1) chitosan powder, from natural, not only can be realized the environmental protection of whole technical process with him as finishing agent;
2) chitosan powder can all can form firmly ionic bond with tea dyestuff, cotton fiber under certain condition and carry out combination, again because chitosan powder itself has antibiotic property, therefore it has improved the antibiotic of DYED FABRICS when improving COLOR FASTNESS.
3) the present invention uses tea dyes COTTON FABRIC, at first with dressing liquid, COTTON FABRIC is arranged, then with the tea dyestuff, the COTTON FABRIC after arranging is dyeed, method is simple to operate, and after textile dyeing, dyefastness is good, the fabric tinctorial yield is high, washability and rub resistance are good, even dyeing, and reappearance is strong;
4) can utilize existing equipment to realize dyeing, not increase equipment, not increase cost;
5) environmentally friendly, there is fungistatic effect preferably, useful to health;
6) do not use metal salt mordant in dyeing course, the real requirement that realizes " natural, healthy, environmental protection ";
7) color and luster primitive simplicity and nature, comply with the pursuit of people to pseudo-classic trend;
8) the present invention also can realize that the taking full advantage of of summer autumn tea resource had to higher economic and social benefit, and market prospects are wide.
