Ecological warm-keeping cotton and manufacturing process thereof

Abstract

The invention provides ecological warm-keeping cotton and a manufacturing process thereof. The ecological warm-keeping cotton has good wind-resistant water-repellent effects, also has a certain sterilization function and is better in warm-keeping effect, lots of raw materials are renewable raw materials, and an environmental protection effect is good. The ecological warm-keeping cotton comprises a warm-keeping layer and a waterproof breathable sterilization layer adhered to one side of the warm-keeping layer, wherein the thickness of the waterproof breathable sterilization layer is 10%-15% of the thickness of the warm-keeping layer, the warm-keeping layer is manufactured from, by weight, 30% of Sorona polymer fiber, 30% of superfine warm-keeping fiber, 30% of three-dimensional hollow warm-keeping fiber and 10% of native cotton fiber through mixing, the waterproof breathable sterilization layer is manufactured from, by weight, 40% of collagen fiber, 20% of bamboo fiber, 20% of seaweed carbon fiber and 20% of nanoscale antibacterial silver ion masterbatch native fiber through mixing, the surfaces of the two sides of the waterproof breathable sterilization layer are coated with treatment layers formed by blending silicon nanoparticles and nano titanium dioxide, and the surfaces of the treatment layers are coated with hydrophobic fluorine quaternary amine silane coupling agent coatings. The manufacturing process of the ecological warm-keeping cotton comprises the steps of automatic material preparation and mixing through a machine, opening, carding, web laying, adhesive spraying, heat setting and rolling.

Description

technical field [0001] The invention relates to ecological warm cotton, in particular to an ecological warm cotton and a manufacturing process thereof. Background technique [0002] The method for manufacturing thermal insulation cotton generally includes the following steps in sequence: opening and mixing fiber raw materials, carding and then combing into a net and shaping. 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 late...

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.
