Ecological heat preservation cotton and production technology thereof

Abstract

The invention provides ecological heat preservation cotton and a production technology thereof. The ecological heat preservation cotton has the good windproof and water-repellent effect and has the certain sterilization function, and the heat preservation effect is better. The ecological heat preservation cotton comprises a heat preservation cotton core, a waterproof breathable layer and a soft close-fitting layer, the heat preservation cotton core is manufactured by mixing 30% of Sorona polymer fiber, 30% of superfine heat preservation fiber, 30% of three-dimensional hollow heat preservation fiber and 10% of native cotton fiber, the waterproof breathable layer is manufactured by mixing 70% of collagenous fiber and 30% of meldable fiber, the waterproof breathable layer is coated with a nanometer silicon particle treatment layer, the treatment layer is coated with a fluorine quaternary amine silane coupling agent coating, a sterilization layer is arranged between the soft close-fitting layer and the heat preservation cotton core, the soft close-fitting layer is fixed to the inner side of the sterilization layer in a flocking mode, and the soft close-fitting layer is composed of short fiber with the length being 0.05-0.2 cm. The manufacturing technology of the ecological heat preservation cotton comprises the steps of automatic machine blending mixing, opening, carding, lapping, glue spraying, heat setting and lap formation..

Description

Technical field [0001] The invention relates to ecological thermal insulation cotton, in particular to an ecological thermal insulation 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 the fiber raw materials to form wool, needle punching on the polyethylene film, and then applying hot melt glue or water-soluble latex such as ethylene-vinyl acetate copolymer emulsion, Acryli...

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.
