Abstract
The invention discloses an ecological dyeing method for traditional Chinese medicine dye of a silk fabric. The ecological dyeing method comprises the following steps of: firstly, dissolving 3-5 percent of chlorogenic acid and jamaicin extract and 2-4 percent of chitosan in acidic buffer, and heating the mixture to 50-60DEG C for fully dissolving dye; secondly, carrying out dyeing treatment on the silk fabric by adopting an impregnation method, wherein in a treatment process, the bath ratio is 1:(30-40), the oscillation frequency is 130r/min, the dyeing temperature is 80-90DEG C and the dyeing time is 60 minutes, and washing and drying a cloth pattern after the dyeing treatment; and thirdly, adding an alkaline treating agent in the dyed silk fabric in the acidic buffer to perform alkali treatment, and reducing the dyed silk fabric to be neutral to enable the dyed silk fabric to achieve an optimal antibacterial effect. The silk fabric prepared by the ecological dyeing method disclosed by the invention can obtain a higher antibacterial effect; meanwhile, textile dyed by the jamaicin and the chlorogenic acid also has certain health-care function of the medicine; and ecological antibacterial functional textile with a high added value can be developed.
Description
Technical field
The present invention relates to dyeing and finishing technology technology, be specifically related to a kind of traditional Chinese medicine dye of silk fabric ecological dyeing method.
Background technology
The chemical dye pollution of ecological environment of textiles industry, is detrimental to health, and dyeing and finishing sewage jeopardizes human ecological environment; And present consumer progressively strengthens for the awareness of safety of textiles, it is desirable to use the textiles of green health, therefore, the dyestuff of natural environmental-protective, dyeing assistant and antiseptic are paid attention to by many scholars and research institution and are favored.In prior art, traditional Chinese medicine dye jamaicin and chlorogenic acid are the green colouring material of the pure natural extracted from Chinese Drug Rhizomes of Coptis and honeysuckle plant, pollution-free, environment-friendly type respectively, it has certain biocidal property to Staphylococcus aureus and Escherichia coli respectively, and possesses certain medicinal health-care function.Traditional Chinese medicine dye has good Environmental compatibility and medicinal health-care function, but its index such as dye-uptake, WASHING COLOR FASTNESS, colour fastness to rubbing being applied to natural fabric is still not ideal.Shitosan is a kind of compound of Polycationic, in acid condition with higher positive charge, has good affinity to fiber.When anionic dye jamaicin and chlorogenic acid dye, shitosan can improve its dyeing rate and dye uptake, also can improve the COLOR FASTNESS of DYED FABRICS, simultaneously, the amino of shitosan transfers ammonium salt in acid condition, destroys bacteria cell wall, can give fabric efficient bacteriostasis property.
In sum, shitosan is applied to jamaicin and chlorogenic acid dyes, the ecological antibiotic functional textile of high added value can be developed.
Summary of the invention
Goal of the invention: the present invention, in order to solve the deficiencies in the prior art, provides a kind of traditional Chinese medicine dye of silk fabric ecological dyeing method.
Technical scheme: a kind of traditional Chinese medicine dye of silk fabric ecological dyeing method, comprises the steps:
(1) 3%-5% chlorogenic acid and jamaicin extract and 2%-4% shitosan are dissolved in acidic buffer, and are heated to 50-60 DEG C dyestuff is fully dissolved;
(2) adopt infusion process to carry out dyeing process to silk fabrics, treatment process is: bath raio is 1: 30-40, and frequency of oscillation is 130r/min, and dyeing temperature is 80-90 DEG C, and dyeing time is 60min, by cloth specimen washing and drying after dyeing process;
(3) basic treatment agent is added to the silk fabrics dyeed in acidic buffer and carry out alkali treatment, to be reduced to neutrality, make it reach best fungistatic effect.
As preferably, chlorogenic acid and jamaicin extract are anionic dye.
As preferably, the acidic buffer pH value in step (1) is 3-5.
As preferably, the basic treatment agent in step (3) is ammonia or ammoniacal liquor.
Beneficial effect: the present invention compared to the prior art, traditional Chinese medicine dye jamaicin, chlorogenic acid and shitosan are combined, because natural antibacterial agent shitosan not only has biocidal property, to traditional Chinese medicine dye, also there is short dye and colour fixation, therefore adopt such dyeing, the Products Eco environmental protection of making also has biocidal property.
