Abstract
The invention provides a method for dying cotton fiber by utilizing tea vegetable dye. In the method, natural tea vegetable dye is extracted from fresh tea leaves, and is utilized to dye cotton fiber by different mordanting methods. After being dyed by the method the invention, the cotton fiber has the advantages of good dyeing color fastness, more color spectrums and good bacteriostatic effect. Through the method, multiple colors can be dyed, the color and lustre are soft, archaic and natural, thus people can feel natural and healthy; the dyed cotton fiber has the characteristics of good dyeing fastness, washing and wear resistance, strong repeatability and uniform dyeing; the existing dyeing equipment is used to dye directly without adding equipment and increasing cost; the method is environmentally friendly and is beneficial to human health; and the method can be applied to clean production of textile industry and can realize large-scale production. The method can efficiently use resources of summer tea and autumn tea, develop and produce tea-dyeing cotton textiles which are environmentally friendly and have archaic, simple and elegant colors and bacteriostatic effect, and the market prospect is broad, thus being capable of not only generating great economic benefits but also obtaining great social benefits.
Description
Technical field
The invention belongs to field of deep tea processing technology, be specially a kind of method of tealeaves vegetable colour dyeing cotton fiber.
Background technology
Tea, tea making are planted and the earliest the country of drinking tea in the world by China, and tea tree planting area and output occupy first place in the world.The physiological activator that tealeaves is rich in---Tea Polyphenols, content account for the 20-35% of its dry weight, and its main component catechin is prone to be oxidized to the Tea Pigment with physiological functions such as removing free radical, anti-oxidant, anti-sudden change, anti-bacteria and anti-virus.But it is rare to develop the Tea Pigment goods at present both at home and abroad, is that the deep processed product of raw material research and development is more rare with the bright leaf of tea.
It is a kind of of plant dyeing technology that tea dyes.The textiles of tealeaves dyeing, color and luster is simple and elegant, simple, has tea flavour.External as Japan, Korea S etc. have developed tealeaves socks, tealeaves underwear, and domestic tea dyes research and still locates the exploratory stage.(1999) such as Deo H.T propose the natural dye of tealeaves as cotton fiber earlier, but it is not good enough to dye effect on it.Zhang Xiaoli etc. (2006) find that Tea Pigment obviously improves the colourability of modified cotton fabric, and green tea dyes the product having enhanced antibacterial action (Zhang Cailing etc., 2008) of cotton fabrics.More than research shows that tealeaves can be used to dye cotton fiber, and tea dyeing and weaving article have certain antibacterial functions, but its coloring effect receives the influence of fabric material, and used tealeaves dyestuff is prepared by fresh leaf by the one-tenth extraction of sampling tea relatively, and production cost will be doubled.China tealeaves annual production is high, and the spring tea price is higher than the summer autumn tea again far away, and the Tea Processing cost increases year by year, thereby the tea grower is unwilling to gather and process the bright leaf of summer autumn tea, the phenomenon of bright leaf " old dead arm head " occurs.Therefore, efficiently utilize summer autumn tea resource, Development and Production is environment amenable, the simple and unsophisticated tea simple and elegant, that have antibiotic effect of color dyes cotton goods, and market prospects are wide, can not only produce very big economic benefit, also can obtain great social benefit simultaneously.
Summary of the invention
Defective in view of existing in the prior art provides a kind of tealeaves vegetable colour to dye the method for cotton fiber, utilizes the tealeaves dyestuff that cotton fiber is dyeed.Through to its COLOR FASTNESS, chromatography and anti-microbial property check, find that tealeaves dyeing COLOR FASTNESS is good, chromatogram is many, good antimicrobial effect.
The present invention realizes through following technical scheme, is the natural dye that from fresh leaves of tea plant, extracts preparation, with dyeing cotton fabric on the different mordant dyeing method, draws the dyeing and the antibacterial effect of different colour systems.
The present invention includes following steps:
(1) the bright leaf of tea is broken, add clear water and extract the tealeaves vegetable colour.Solid-liquid ratio is that weight ratio, extraction temperature and extraction time are controlled at 1 respectively during extraction: 10-50,10-30 ℃ and 0.5-1h, and concentrated, the drying of will filtrate after lixiviate finishes is the tealeaves vegetable colour;
(2) dye on carrying out at adding tealeaves vegetable colour on the cotton fiber, the pH value of dye liquor is 3-4.5, and bath raio is 1: 10-50 (weight ratio), 30-70 ℃ of dye bath temperature, dyeing time 0.5-4h;
(3) dye preceding on the cotton fiber or on dye the back with mordant dyeing (matchmaker's method or back matchmaker's method in advance).Mordant consumption and tealeaves vegetable colour mass ratio are 1: 1-2, bath raio is 1: 10-50,30-70 ℃ of dye bath temperature, mordant dyeing time 0.5-4h.
Described tealeaves vegetable colour contains the pigment composition Tea Polyphenols more than 30%.
The used mordant of described tealeaves vegetable colour is aluminium salt or mantoquita.
The tealeaves vegetable colour is perfect not enough to the research work of dying aspects such as mechanism, Adsorption thermodynamics and dynamics on the cotton fiber.But mordant all has affinity to coloring material and fiber, can form coordinate bond and fixation with the metal ion that is adsorbed on the fiber during vegetable colour dyeing, and can produce different form and aspect, and can increase dyefastness.The present invention utilizes the characteristics of mordant dyeing, and the colouring method that a kind of COLOR FASTNESS is good, chromatogram is many is provided.The natural dye that the present invention uses tealeaves to extract can dye multiple color, and color and luster is soft, simple and unsophisticated, natural, gives people's's a kind of " natural, health " impression; Dyefastness is good, washable antifriction, and reappearance is strong, even dyeing; Utilize existing dyeing installation direct dyeing, do not increase equipment, do not increase cost; Environmentally friendly, useful to health; Be applied to the cleaner production of textile industry, can produce in a large number.The present invention efficiently utilizes summer autumn tea resource, and Development and Production is environment amenable, the simple and unsophisticated tea simple and elegant, that have antibiotic effect of color dyes cotton goods, and market prospects are wide, can not only produce very big economic benefit, also can obtain great social benefit simultaneously.
