Abstract
The invention discloses an anti-scratch warm-keeping down quilt cover and a preparation method thereof, and relates to the technical field of fabrics. The scratch-proof warm-keeping down quilt cover is prepared by wrapping a skin-friendly layer with a scratch-proof layer; the skin-friendly layer is made of bamboo fiber fabric, so that the composite material enters a bamboo fiber hollow structure formed by bamboo pulp to form a moisture-conducting passage, and the moisture conductivity of the skin-friendly layer is enhanced; the scratch-resistant layer is a cellulose composite film, and cellulose microspheres are embedded in the polyethylene imine film, so that the crosslinking density of the cellulose composite film is increased, and the scratch resistance of the scratch-resistant layer is enhanced; the cellulose composite membrane enters the pores of the skin-friendly layer, so that the porosity is reduced, the cellulose microspheres further connect the moisture-conducting passages, and the moisture conductivity and the warmth retention property of the down quilt cover are enhanced.
Description
Technical Field
The invention relates to the technical field of fabrics, in particular to an anti-scratch warm-keeping down quilt cover and a preparation method thereof.
Background
The quilt cover is a cover sleeved outside the quilt, can be changed and washed at any time, is made of multipurpose cloth or is a necessary household article for every family, and is sleeved outside the quilt core; most of the existing quilts are pure cotton quilts, bamboo fiber quilts and satin quilts, the cotton fibers have good hygroscopicity, are porous, have good heat preservation, and the satin fabric has the advantages of moisture absorption and heat resistance
The bamboo fiber quilt cover has higher air permeability than cotton fibers, has the functions of bacteriostasis, mite prevention and deodorization, has adsorptivity and can adsorb peculiar smell; however, when the down quilt cover is used, the warm keeping performance is insufficient due to the excessively high air permeability, the moisture permeability and sweat discharging performance are poor, and meanwhile, the scratch-proof effect cannot be achieved; therefore, the invention researches and prepares the anti-scratch warm-keeping down quilt cover.
Disclosure of Invention
The invention aims to provide an anti-scratch warm-keeping down quilt cover and a preparation method thereof, so as to solve the problems in the background technology.
