Environmental-friendly fiber cotton and preparation process thereof

Abstract

The invention discloses environmental-friendly fiber cotton and a preparation process thereof, in particular to a method for preparing the fiber cotton by mixing fiber with low melting point with corn fiber and soybean fiber and performing heat treatment and a product. The preparation process comprises the following steps of: preparing raw materials from 10%-30% of the fiber with low melting point and 90%-70% of one or two of corn fiber and soybean fiber through mixing; carrying out cutting, cotton carding, forming and hot baking adhesion on the prepared raw materials in sequence; carrying out pressing, rolling, rapid cooling and shaping simultaneously when the raw materials are still hot; and then cutting and packaging according to the requirements, wherein the temperature for hot baking shaping is 110-130 DEG C, and the adoption of air-laying and rapid cooling shaping technologies has an important significance in improving the quality of the fiber cotton. The corn and soybean fiber cotton disclosed by the invention can be biodegraded completely and comprehensively improve a fiber air-laid structure simultaneously, and the product can be naturally degraded under the action of microbes after being disused and is further different from chemical fiber cotton which needs to consume a large number of non-renewable petroleum resources and is still difficult to degrade, so that the fiber cotton disclosed by the invention is an ecological raw material with great development potentiality.

Description

Technical field [0001] The present invention relates to a kind of environmental protection fiber cotton preparation process, more specifically, the present invention relates to A method for preparing fiber cotton by mixing and heat-treating low-melting fiber (hot-melt fiber) with one or both of corn fiber and soybean fiber, and the invention also relates to the environmentally friendly fiber cotton produced by the process. Background technique [0002] Mattresses, sofa seat cushions, flakes and other household items that we use a lot in modern life, women's sanitary napkins, panty liners, baby diapers (sheets), wet face towels, disposable surgical gowns, masks, medical surgical tablecloths, nursing sheets A large number of fiber cotton products produced by chemical fiber are used in fields such as sanitary products, sound-absorbing and heat-insulating materials for automobile construction, industrial air pre-filtering and industrial filter materials, clothing linings and th...

Problems solved by technology

[0008] Since the fibers of spray-bonded cotton are mainly distributed in two dimensions, it has poor strength, poor elasticity and wear resistance and is easy to peel off.
