Adopted Shengma fibers have good impregnation effect, the photocatalytic property and the bacteriostasis of textiles are improved, the processed textiles have the best waterproof effect, durability and flame retardance, and the wax ingredient in the textiles enable obtained fabrics to be fine, natural and attractive in surface pattern.
Description
Technical field
The invention belongs to textile processing techniques field, be specifically related to a kind of preparation method of antibacterial flame-retardant textiles.
Background technology
Sheng-bast fiber be Ji Gao chemical fibre Co., Ltd of Hebei province with numb plants such as natural jute, bluish dogbanes for raw material, utilize proprietary technology to be made into pulp, then a kind of New Viscose Fibre of producing of melt-out spinning.In its production process, remain natural bacteriostatic, mildew-resistant material that numb material has to greatest extent, and its grafting is not damaged on Sheng-bast fiber macromolecular chain.Sheng-bast fiber has good biocidal property and antibacterial effect.Sheng-bast fiber has the dry strength approximate with common viscose fiber, higher than the wet strength of common viscose fiber and sky bamboo fibre.From fibre structure, it longitudinally has many stripeds; Cross section is plum blossom and star, has groove mark, irregular.Because the large intermolecular hydrogen bonding of regenerated cellulose is less, the structure of adding it is quincunx, and there is groove mark on surface, so its hygroscopicity, gas permeability are better, energy moisture absorbing and sweat releasing, to the sensation that people feels nice and cool.
Textiles is the daily indispensable daily necessitiess of people, because textiles is formed primarily of fiber, also becomes the main material of initiation fire, causes great life and property loss to society.But existing flame retardant textiles is be sleeved on outside textile fibre layer by fire proofing mostly, so long-time dress is uncomfortable.In addition, in prior art, textiles is carrying out in the process processed, and because the wax face of fabric face easily comes off, thus cause the generation of dyeing defect, the quality scale of textile product is difficult to get a promotion always.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of preparation method of antibacterial flame-retardant textiles, the Sheng-bast fiber adopted, dipping effect is good, improve photocatalysis performance and the biocidal property of textiles, textiles after process reaches best waterproof effect, durability, anti-flammability, wax component wherein, makes that the fabric face lines that obtains is meticulous, natural beauty.
The technical scheme that the present invention takes is:
A preparation method for antibacterial flame-retardant textiles, is characterized in that, specifically comprises the steps:
(1) nano silver colloidal sol processed: the concentrated ammonia liquor of 30-33% is added in deionized water in the ratio of 0.3mL/L, stir continuously with the speed of 220-230rpm, with the NaOH aqueous solution of 0.5M, the pH value of solution is adjusted to 9-10, add 0.08-0.12mM reductant, 0.1-0.12mM silver nitrate, lucifuge stirring reaction 30-35min;
(2) waterproof flame retardant processed: the zinc chloride getting polyurethane 15-18%, wax 6-8%, 3-5% deca-BDE and 18-22% according to percentage by weight, is dissolved in ethanol solution, is uniformly mixed;
(3) sol impregnation liquid processed: add in nano silver colloidal sol according to the ratio of 3-4g/L by above-mentioned obtained waterproof flame retardant, after mechanical agitation 20-25min, carries out ultrasonic disperse 4-6min;
(4) textile treatment: immersed completely by textiles in sol impregnation liquid, ultrasonic vibration 1.8-2.2h, takes out textiles after removing the solution of its excess surface, wash 3 times with ethanol, put into the baking oven of 72-74 DEG C, dry 80-100min, to be diluted dose volatilizees completely, is cooled to room temperature.
Further, the reductant in described step (2) is sodium borohydride.
Further, the wax in described step (2) is the mixture that rosin and paraffin form according to weight ratio 2:3.
Further, in described step (3), waterproof flame retardant and nano silver colloidal sol mix according to the ratio of weight ratio 1:15-17.
Further, in described step (4), Sheng-bast fiber selected by textiles.
Beneficial effect of the present invention is:
In sol impregnation liquid, nano silver particles and zinc oxide are combined closely mutually by electrostatic force, nano silver particles is evenly distributed on the surface of zinc oxide, improve photocatalysis performance, the Sheng-bast fiber that the present invention adopts, raw material itself has good biocidal property, by infiltrating sol impregnation liquid, silver-ZnO is processed textile surface, make it have the antibacterial activity of nano composite structure, waterproof flame retardant in the present invention makes textiles reach best waterproof effect and durability, deca-BDE serves flame retardant effect, wax component wherein, make the fabric face lines that obtains meticulous, natural beauty.
