Novel environment-friendly elastic fiber combination filling material and preparation method thereof

Abstract

The invention provides a novel environment-friendly elastic fiber combination filling material and a preparation method thereof. 3D upright cotton is a food-grade PET high-elasticity fiber material, so that oxidative decomposition and yellowing of a product are avoided. The product itself is of an upright fiber net structure, thereby being more breathable than common foamed materials. The 3D upright cotton is produced by physical forming, so that waste gas and waste solid are not generated, and environment pollution is avoided; food-grade liquid silica gel impregnation and adsorption processesare pure physical processing techniques, so that no harmful substance is used and generated during production, and transverse-longitudinal tension and elasticity of a 3D upright cotton fiber elastomer material are improved greatly. A food-grade PET base material and food-grade liquid silica gel are highly inert materials and are basically not in chemical reaction with any substance for degeneration, so that allergic reaction of using people caused by harmful substances generated by oxidation is avoided; elasticity and softness completely conform to ideal requirements of people, so that comfort and happiness of the people when using the product are improved.

Description

Technical field [0001] The invention relates to the field of elastic fiber materials, in particular to a novel environmentally friendly elastic fiber combined filling material and a preparation method thereof. Background technique [0002] Existing foaming elastomer materials used in PU foaming materials such as latex and sponge cannot resist the oxidation reaction during normal temperature use. Traditional latex and sponge products are in contact with air and human body for a long time during use. It is easily oxidized with sweat discharged from the human body, dust and oxygen in the air to produce harmful substances. In the production process of traditional PU foam materials, freon is used, and a large amount of carbon dioxide and diisocyanate (toxic gas) are generated, which causes great pollution to the human living environment. The purity of natural latex is generally only 20%-40%, and most of the ingredients in natural latex are proteins and sugars. Alkali chemical synthes...
