Technical Field

The invention relates to the field of textile fabrics, in particular to a manufacturing method of a mothproof and anti-static pure cashmere fabric and an obtained fabric product.

Background

Cashmere is a thin layer of fine down grown on the outer cuticle of a goat and covered at the root of the goat's coarse hair. It is light in weight, soft and good in toughness; the air-permeable cold-proof air bag contains a lot of air, forms an air layer, can prevent the invasion of external cold air, keeps the body temperature and does not reduce, and has excellent performance of resisting wind cold. Cashmere fabric woven from cashmere raw material is also considered as the highest-grade textile fabric. Because of containing a large amount of keratin protein, the cashmere is easy to emit odor, attracts insects such as clothiantus moth to eat, forms moth-eaten holes, and after a long time, holes which are bitten are formed, thereby greatly reducing the service life of the fabric and causing unnecessary loss, therefore, the wool mothproof finishing has important significance.

Common mothproof finishing methods include a chemical modification method and a mothproof agent finishing method. The chemical modification of the wool and cashmere fiber is to form a new and stable cross-linked structure through chemical modification, and when eating the cross-linked structure, moths are difficult to digest and finally killed; but the cashmere structure is easy to change, and the cashmere hand feeling is affected. The finishing method of moth-proofing agent is characterized by that the cashmere fibre is directly carried with chemical medicine which can kill moth, and these chemicals can be directly soaked in the cortex of moth or can be poisoned by respiratory organ and digestive organ to kill moth. The chemical modification method of wool and the finishing method of mothproofing agent can bring different pollutions, especially the finishing method of mothproofing agent has higher toxicity to environment and human body and can cause public nuisance, and the finishing method of mothproofing agent can disappear gradually along with the treatment such as dry cleaning in the using process, loses the mothproofing effect and is not washable.

Therefore, there is a need for an improved method for preventing moth-eating cashmere fabric.

Disclosure of Invention

The invention aims to provide a method for manufacturing mothproof and anti-static pure cashmere fabric which is green and environment-friendly and has lasting mothproof effect.

The technical problem to be solved by the invention is to provide a fabric product obtained by the manufacturing method of the mothproof and anti-static pure cashmere fabric which is green, environment-friendly and durable in mothproof effect.

The technical problem to be solved by the invention is realized by the following technical scheme: a manufacturing method of mothproof and anti-static pure cashmere fabric comprises the following steps: s1, selecting pure cashmere fibers; s2, performing moth-proofing treatment on cashmere fibers: preparing methyl cellulose, oxidized sodium alginate with double aldehyde groups, bacillus thuringiensis and water into a treatment solution; adding the pure cashmere fibers into the treatment fluid for dipping and ultrasonic microencapsulation; adding ethanol, mixing, standing, and precipitating; centrifugally spin-drying, taking out and drying the cashmere to obtain mothproof cashmere fibers loaded with bacillus thuringiensis microcapsules; s3, spinning and twisting: adding 2-5% of wool oil and water into the mothproof cashmere fibers, controlling the moisture regain of the fibers to be 17-20%, uniformly permeating the wool oil and the water, carding and spinning to obtain mothproof cashmere yarns, and twisting the yarns; s4, weaving: weaving the twisted yarn into fabric grey cloth; s5, after finishing: finishing the fabric grey cloth by using a finishing liquid containing an antistatic agent; and S6, drying and shaping.

The bacillus thuringiensis is microencapsulated by methylcellulose and sodium alginate oxide, the capsule has good toughness flexibility and transparency, so that the bacillus thuringiensis is resistant to washing and illumination, and covalent crosslinking is rapidly generated through the reaction of double aldehyde groups of the sodium alginate oxide and amino groups of cashmere fibers in an alcohol solution, so that the microencapsulated bacillus thuringiensis is precipitated and grafted on the surfaces of the cashmere fibers, and mothproof components can be uniformly dispersed in the cashmere fibers and permeate into cashmere fiber molecules, thereby introducing the bacillus thuringiensis, which has a good effect of killing moths, into the cashmere fibers. Compared with a chemical insecticide, the bacillus thuringiensis has a good effect of killing moths, is environment-friendly and harmless to people and livestock, and the added auxiliary agent does not influence the texture of cashmere.

Preferably, in step S1, the pure cashmere fibers are white cashmere fibers having a fineness of not more than 16 μm and a length of 34 to 36 mm.

In the step S2, the preferable technical scheme is that the preparation method of the treatment solution includes heating water to 80-90 ℃, adding methylcellulose to swell, cooling to a temperature not higher than 40 ℃, adding oxidized sodium alginate to dissolve, and adding bacillus thuringiensis. Such temperature control is beneficial to promote the dissolution of methylcellulose, so that the system can keep a viscous solution state, and the survival rate of the bacillus thuringiensis in the process of preparing the treatment solution can be kept high.

Further preferably, in step S2, the weight percentage concentrations of the methylcellulose and the oxidized sodium alginate in the treatment solution are 1-4% and 0.5-3%, respectively.

Further preferably, in step S2, the concentration of the bacillus thuringiensis in the processing solution is 1-3% by weight.

Further preferably, in step S2, the bath ratio of the pure cashmere fibers to the treatment liquid is 1: 10-1: 20; the immersion time of the pure cashmere fiber in the treatment liquid is 0.1-2 hours, and the ultrasonic time after the immersion is 0.2-1 hour.

Further preferably, in the step S2, in the step S2, ethanol is added in an amount of 0.1 to 0.5 times the volume of the treatment solution, and the mixture is allowed to stand and precipitate for 3 to 10 hours after the addition of ethanol.

Further preferably, in the step S2, in the step S2, the spin-drying rotation number is 1200-1500 rpm, the drying is low-temperature vacuum drying, and the drying temperature is 20-50 ℃. The low temperature vacuum drying is beneficial to maintain the high survival rate of the bacillus thuringiensis before the bacillus thuringiensis is formed into the microcapsule.

Preferably, the step S5 is: soaking the fabric grey cloth in water containing an antistatic agent for 5-30 minutes at the temperature of 40-45 ℃ in a bath ratio of 1: 10-1: 15, the weight percentage of the antistatic agent is 2-4%. Further preferably, the antistatic agent is a permanent antistatic agent Tanastax WP.

The invention also comprises a fabric product obtained by the manufacturing method of the mothproof anti-static pure cashmere fabric.

Compared with the prior art, the invention has the advantages and beneficial effects that: according to the invention, the biological agent bacillus thuringiensis is introduced into the pure cashmere fabric, the stability of the bacillus thuringiensis is improved through microencapsulation, the microencapsulated bacillus thuringiensis is grafted and fixed in the cashmere fibers, and the biological agent mothproofing agent permeates into the fibers, so that the produced mothproofing effect does not influence the texture of the cashmere, and the biological agent is environment-friendly and harmless to human and livestock.
