Description
Technical Field
The invention relates to the field of textile fabrics, in particular to a mothproof pure cashmere fabric and a manufacturing method thereof.
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 a thin and curved fiber, the fineness is generally between 13 and 15.5 microns, and the length of raw velvet is 30 to 55 millimeters; cashmere is much finer than wool, and outer-layer scales are finer and smoother than wool, so that the cashmere is light in weight, soft and good in toughness; the fiber gem contains a lot of air, forms an air layer, can prevent the invasion of external cold air, keeps the body temperature without reducing, has excellent wind cold resistance, and is considered as a fiber gem. Cashmere fabric woven from cashmere raw material is also considered as the highest-grade textile fabric. According to the national standard, the pure cashmere fabric has the standard that the content of cashmere reaches more than 95%.
Because of containing a large amount of keratin protein, the cashmere is easy to emit odor, and attracts insects like clothiantus moth to eat, thereby forming holes which are damaged by worms and bitten after a long time, and greatly reducing the service life of the fabric. As a medium-high grade fabric, the cashmere fabric needs to be protected from moth eating. The common fiber or fabric products are made by adding mothproofing agent into the cabinet in which the fiber or fabric products are stored; however, compared with chemical fibers, cashmere is a more delicate natural fiber, and the physical properties of cashmere can be damaged and the cashmere is deteriorated or faded due to the fact that the cashmere is in direct contact with the mothproofing agents. Generally, the cashmere sweater decoration is hung above the cashmere sweater decoration by sewing an insect repellent in a sachet, but the method is inconvenient for storing and moving the cashmere sweater decoration. In order to prevent the fabric from being damaged by worms, the more advanced method is to use a mothproofing agent for finishing when the yarn or the fabric is manufactured. For example, the chinese patent with application number 201010139996.6 is to pretreat wool with stemona mothproofing agent with a certain concentration to make it have mothproof effect. But the mothproof effect gradually disappears after a plurality of times of water washing. In order to improve the slow release effect, the microcapsule used for functional after-finishing of textiles is prepared by wrapping lavender mothproof essential oil with beta-cyclodextrin. However, the inclusion material beta-cyclodextrin has low water solubility at normal temperature, and has good solubility only when the water temperature is higher than 60 ℃, so that the included lavender essential oil can be released, and the good mothproof effect can be exerted. However, cashmere fabrics shrink and deform in aqueous solution at the temperature of more than 30 ℃, and the washing temperature is not more than 40 ℃, so that the beta-cyclodextrin inclusion lavender essential oil microcapsules are used for after-treatment to improve the mothproof property of the fabrics, and the essential oil is not suitable for the cashmere fabrics, and the repelling mechanism of the essential oil is that moths usually avoid a signal source of plant essential oil containing aromatic odor or are repelled by the plant essential oil to reduce the invasion to the cashmere products, but worm eggs and larvae can not be killed, and only the effect of preventing the moths can be achieved.
Therefore, there is a need for an improved method for preventing moth-eating cashmere fabric.
