Ecological cotton and production technology thereof

Abstract

The invention provides ecological cotton and a production technology thereof. The ecological cotton has a better warm-keeping effect and comprises a warm-keeping cotton core, a 3D flocking layer and a soft close-fitting layer, wherein the warm-keeping cotton core is made of 30% of Sorona polymer fibers, 60% of superfine warm-keeping fibers and 10% of raw cotton fibers through mixing; the 3D flocking layer comprises elastic base cloth, a 3D flocking surface layer arranged on the surface of the elastic base cloth and a vacuum cotton filling layer arranged between the elastic base cloth and the warm-keeping cotton core; the soft close-fitting layer comprises a metal aluminum foil film layer fixed with the warm-keeping cotton core and a planar flocking lining arranged on the surface of the metal aluminum foil film layer, and the 3D flocking surface layer and the planar flocking lining are both made of short fibers with the length of 0.05-0.2 cm. The production technology of the ecological cotton comprises steps as follows: automatic blending and mixing by a machine, opening and scutching, carding, lapping, adhesive spraying, heat setting and coiling.

Description

Technical field [0001] The invention relates to ecological cotton, in particular to an ecological cotton and its production process. Background technique [0002] The method of manufacturing thermal cotton generally includes the following steps in sequence: opening and mixing the fiber raw materials, carding the cotton into a net and shaping it. At present, most of the shaping process uses plastic film combined with needle punching or adhesive application to shape the fiber web. For example, Chinese patent application ZL94101293.X describes opening and carding the fiber material into a net, and superimposing it with a polyethylene film, and forming a composite thermal cotton by needle punching and rolling. Chinese patent ZL98203205.6 describes opening fiber raw materials to form wool, needle punching on a polyethylene film, and then applying hot melt glue or water-soluble latex such as ethylene-vinyl acetate copolymer latex, Acrylic copolymer emulsion, etc., are made into warm-...

AI Technical Summary

Problems solved by technology

Chinese patent ZL98203205.6 describes that the fiber raw material is opened to form plush, which is needle-punched onto a polyethylene film, and then hot-melt adhesive or water-soluble latex such as ethylene-vinyl acetate copolymer latex, Acrylic copolymer emulsion, etc., to make warm composite fleece. Although the products made in this way have good warmth retention, the air permeability and moisture permeability are not very ideal, and they are not washable.

[0003] Moreover, most of the existing ones commonly used are ordinary regenerated fibers (including fluorescent whitening agent), the product feels rough, and the washing performance and heat preservation performance are not ideal.
