Abstract
The present invention discloses an antibacterial processing method of yarn, which comprises the steps that antibacterial agents and wax are merged to manufacture antibacterial wax blocks used for yarn; the waxed yarn is heated in water vapor so as to make the antibacterial agents permeate into the yarn to be fixed on the surfaces of fibers. In the method, the antibacterial agents and the wax need dissolving in organic acid water solution before being merged, and surfactants are added for manufacturing mucilage glue, wherein the dosage of the acid accounts for 20 to 50% of the weight of the antibacterial agents, the weight ratio of the antibacterial agents to the wax is from 5 to 40%, and the waxing amount of the yarn accounts for 0.1 to 2% of the weight of the yarn. The method has the advantages of low cost and application flexibility.
Description
Technical field
The present invention relates to a kind of antibiotic processing method of yarn, it is that a kind of utilization mode of waxing makes antimicrobial-coated outer surface in yarn, infiltrates through the antibacterial processing method of yarn inside again by antiseptic by steam fusion wax.
Technical background
Existing antibacterial textile process technology has dual mode:
One, the making of anti-bacterial fibre: synthetic fiber are about to antiseptic sneak in the molten mass or solution body of fiber polymer when making, promptly obtain having the fiber of antibacterial effect through spinning process.
Two, the processed of fabric:, allow antiseptic infiltrate the inner contact of cloth fiber surface, and obtain anti-bacteria cloth to the fiber cloth processing that is made into.
Generally speaking, first kind is carried out antibiotic processing for inchoate fiber, have the lasting function of its antibiotic property, but cost of manufacture is higher, and the interpolation of antiseptic can influence skin-friction coefficient and other rerum natura of fiber, is unfavorable for spinning and weaves cotton cloth.And second kind of antibiotic processing for cloth has lower-cost advantage, but influences the sense of touch of fiber surface because using the resin of processing contact, not water-fast even washing, and antibacterial effect can't be lasting.
The content of invention
Therefore, the inventor is the shortcoming that alleviates and overcome above-mentioned antibiotic processing mode, adopts yarn as antibiotic processing object, with the purpose that reaches durable antibiotic property and reduce production costs simultaneously.
In Textile Engineering, can be woven into cloth smoothly for making yarn, generally all must be by the operation of waxing, to reduce the coefficient of friction of yarn, to avoid on loom, causing broken yarn or abrasion machinery.
The present invention uses the mode of waxing, the wax of antiseptic and fiber use is mixed into antibiotic wax stone, then, antibiotic wax stone is attached to fiber surface, then allow antiseptic infiltrate set among the yarn along with the fusion of wax through Overheating Treatment again, to obtain making yarn have the effect of antibacterial ability.
Antiseptic among the present invention comprises antimicrobial component, aqueous solutions of organic acids and surfactant.Described antimicrobial component is chitosan (chitosan), carboxymethyl chitosan (carboxymethylchitosan) and 2,4,4 '-three chloro-2 '-hydroxyl-diphenyl ether (2,4,4 '-trichloro-2 '-hydroxy-diphenylether) one of them or two or three combination, their chemical formula is as follows:
R1=H or COCH

Carboxymethyl chitosan (carboxymethyl chitosan)
2,2,4 '-three chloro-2 '-hydroxyl-diphenyl ether (2,2,4 '-trichloro-2 '-hydroxy-diphenylether)
Above-mentioned antimicrobial component is dissolved in the organic acid aqueous solution, adds surfactant again, be mixed with mucus, just made antiseptic of the present invention.
In the antibiotic processing method of yarn of the present invention, wherein antiseptic is with before fiber mixes with wax, earlier antimicrobial component is mixed with solution with organic acid, its organic acid can be any one or more the combination in acetic acid, acrylic acid, malonic acid, adipic acid, lactic acid, malic acid, citric acid, maleic acid, gluconic acid and the glutaric acid, and the organic acid consumption is the 20-50% of antiseptic weight.
During with antiseptic and wax fusion use, antiseptic accounts for the 5-40% of the weight of wax.
The antibiotic processing method of yarn of the present invention, wherein the amount of waxing of yarn is the 0.1-2% of yarn weight, and the steam heat treated temperature of the back yarn of waxing is 80-120 ℃, and the processing time is 30-60 minute.
In the antibiotic processing method of yarn of the present invention, wherein said yarn is the staple fibre yarn and the blended yarn of cotton, fiber crops, hair, polyester, or the fine yarn of length of polyester, polyamide, polyacrylonitrile, polyurethane, or the long fiber of any material is as cotton, fiber crops, the hair wrap yarn of core.
The antibiotic processing method of yarn of the present invention has following characteristics:
1. the present invention reaches " steam heating " two existing weaving operations yarn is processed to obtain antimicrobial yarn in conjunction with " waxing ".Therefore on equipment, can continue to use existing manufacturing equipment, when carrying out antibiotic processing, also finish yarn lubricated (purpose that oils) and typing (purpose of steam heating), yarn is beneficial to weave.
2. the present invention carries out antibiotic processing in yarn stage and obtains antibiotic yarn, can carry out antibiotic processed for the fine wrap yarn of various staple fibre yarns, blended yarn, length of natural fabric or synthetic fiber composition, on using, compare, have the low high advantage of application flexibility simultaneously of cost with the antibiotic processing method of fiber stage.
3. solid state wax and steam are the media of antiseptic and fibration, and solid state wax is taken antiseptic to yam surface, and steam makes antiseptic and wax break away from, and accept the set that antiseptic is finished its input yarn inside antiseptic and fiber.So still contain wax according to its surface of antibiotic yarn of made of the present invention, and as lubricating of yarn, and, yarn gets final product the eccysis wax when being made into later the needing only with alkaline warm water of cloth, obtain anti-bacteria cloth.
In order to further specify example of the present invention and mode, enumerate three embodiment below, carry out antibiotic processed with as an illustration at the long fine cotton wrap yarn of silk floss/polyester blended yarn, polyurethane and nylon yarn (Nylon) respectively, and carry out its antibacterial effect of experiment confirm.
