Water-absorbent non-woven fabric and preparation method thereof as well as medical non-woven fabric

Abstract

The invention belongs to the non-woven field and in particular provides a water-absorbent non-woven fabric which is mainly formed by cohering a water-absorbent layer and spun-bond non-woven fabrics at two sides of the water-absorbent layer together, wherein the water-absorbent layer consists of multiple layers of netlike polymer water-absorbent resin fiber layers. The invention also provides a method for preparing the water-absorbent non-woven fabric by adopting a method combining a textile technology with needling. The water-absorbent non-woven fabric provided by the invention is particularly suitable for the fields of filtration and clothing and is excellent in water absorbability and good in water retaining capacity. The invention also provides a medical non-woven fabric mainly comprising the water-absorbent non-woven fabric. The achieved beneficial effects are that the water-absorbent non-woven fabric provided by the invention is good in water absorbing property, good in tensile elasticity and good in ductility and cannot be broken easily. The preparation method of the water-absorbent non-woven fabric is simple in step and is suitable for popularization, and the obtained water-absorbent non-woven fabric is more stable in structure. The medical non-woven fabric provided by the invention is not adhesive to wounds and has TDP treatment functions at the same time, and the effect of TDP treatment is better and quicker.

Description

technical field [0001] The invention belongs to the non-woven field, and in particular relates to a water-absorbing non-woven fabric, a preparation method thereof and a medical non-woven fabric composed of the water-absorbing non-woven fabric. Background technique [0002] Non-woven fabrics are commonly known as non-woven fabrics. It is a non-woven fabric formed by directional or random arrangement of short fibers or filaments to form a web structure, and then reinforced by mechanical, hot rolling or chemical methods. Absorbent non-woven fabric is a kind of non-woven fabric, which is widely used in clothing materials, filter materials, wastewater treatment, sanitary products, medical products, chemical products and other fields. Most of the traditional absorbent non-woven fabrics are directly combined with multi-layer non-woven fabrics. Since non-woven fabrics are mostly composed of short fibers and filaments arranged randomly, after the water-absorbing non-woven fabric for...

AI Technical Summary

Problems solved by technology

Since non-woven fabrics are mostly composed of short fibers and filaments arranged randomly, after the water-absorbing non-woven fabric formed absorbs water and swells, the interaction force between the short fibers and filaments weakens sharply, resulting in loss of tensile elongation. Sexuality, there is a shortcoming of being stretched and easily broken

At the same time, traditional water-absorbent non-woven fabrics still have disadvantages such as poor water absorption capacity, short water retention time, and unfriendly to the environment.
