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.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the present invention discloses an ecological cotton, which includes a thermal insulation cotton core 1, a 3D flocking layer arranged on the outside of the thermal insulation cotton core 1, a soft close-fitting layer arranged on the inner side of the thermal insulation cotton core 1, and the 3D flocking layer The thickness of the cashmere layer is 20%-30% of the thickness of the thermal insulation cotton core 1, the thickness of the soft close-fitting layer is 30%-40% of the thickness of the thermal insulation cotton core 1, and the thermal insulation cotton core 1 is calculated by weight percentage. It is made of 30% Sorona polymer fiber, 60% superfine thermal fiber, and 10% virgin cotton fiber. The 3D flocking layer includes elastic base fabric 6, which is arranged on the elastic base cloth 6 by 3D flocking. ...

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 a production process thereof. Background technique [0002] The method for manufacturing thermal insulation cotton generally includes the following steps in sequence: opening and mixing the fiber raw materials, carding into a net and shaping after carding. At present, most of the shaping process adopts the method of combining plastic film with acupuncture or applying adhesive to shape the fiber web. As described in Chinese patent application ZL94101293.X, the fiber raw material is opened, combed into a net, and superimposed with a polyethylene film, which is needled and rolled to form a composite thermal insulation cotton. 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 ...
