Embodiment 1

[0025] A low temperature resistant non-woven fabric, its composition includes: polypropylene 10kg, natural cellulose 30kg, water-based polyurethane 5kg, acrylic emulsion 15kg, cyanate resin 5kg, polyimide 5kg, aluminum oxide with an average diameter of 3.5μm 1 kg of fibers, 1 kg of glass fibers with an average diameter of 5.0 μm, and 1 kg of lanthanum oxide. The base material and the binder are mixed into a slurry, and the water is removed by a vacuum film evaporator to form a spinning dope, which is extruded from the spinning port by a melt-blown method to form a cellulose tow, which is then mixed with a reinforcing agent under high temperature conditions. Coagulation regeneration, water washing, spunlace and drying to make low temperature resistant non-woven fabric. The low-temperature-resistant nonwoven fabric prepared under this condition has good low-temperature resistance effect, is non-toxic, non-irritating, safe and environmentally friendly.

Embodiment 2

[0027] A low temperature resistant non-woven fabric, its composition includes: polypropylene 15kg, natural cellulose 35kg, water-based polyurethane 7kg, acrylic emulsion 20kg, cyanate resin 7kg, polyimide 7kg, aluminum oxide with an average diameter of 3.5μm 3 kg of fibers, 3 kg of glass fibers with an average diameter of 5.0 μm, and 3 kg of lanthanum oxide. The base material and the binder are mixed into a slurry, and the water is removed by a vacuum film evaporator to form a spinning dope, which is extruded from the spinning port by a melt-blown method to form a cellulose tow, which is then mixed with a reinforcing agent under high temperature conditions. Coagulation regeneration, water washing, spunlace and drying to make low temperature resistant non-woven fabric. The low-temperature-resistant nonwoven fabric prepared under this condition has good low-temperature resistance and good elasticity.

Embodiment 34

Abstract

The invention discloses a low-temperature-resistant nonwoven fabric. The low-temperature-resistant non-woven fabric includes a base material, an adhesive and a reinforcing agent. The low-temperature-resistant non-woven fabric is prepared by mixing the base material and the adhesive into a slurry, and the low-temperature-resistant non-woven fabric is prepared by a vacuum film evaporator. Remove water to form spinning viscose, and extrude the viscose from the spinning port to form cellulose tow by means of melt blown, and make low temperature resistant non-woven fabrics through coagulation regeneration, water washing, spunlace and drying under high temperature conditions. Cloth, the base material is polypropylene and natural cellulose, the binder is water-based polyurethane, acrylic emulsion, cyanate resin, polyimide, and the reinforcing agent is aluminum oxide fiber, glass fiber, and rare earth oxide. The low-temperature resistant non-woven fabric of the invention is cold-resistant, has good toughness, waterproof, and has excellent physical and mechanical properties. At the same time, the product has a flexible hand feeling, good elasticity, contains rare earth oxide components, has a long service life and stable quality.

Description

technical field [0001] The invention belongs to the field of manufacturing textiles, and in particular relates to a low-temperature resistant non-woven fabric. Background technique [0002] In recent years, the manufacture of non-woven fabrics and various products have penetrated into various fields of the national economy. With the development of non-woven fabric technology and the demand for further improvement of the performance of non-woven fabric products, composite non-woven fabrics and related products have developed rapidly. The so-called composite non-woven fabric refers to two or more materials, at least one of which is non-woven fabric combined in some way to become a new functional material that a single material does not have. After different composite finishing processes, the application of non-woven fabrics can be extended to many untouched fields, and the performance of non-woven fabrics can be greatly improved and enhanced. However, although our country ha...
