AI Technical Summary

Problems solved by technology

However, the synthesis of polyurethane raw materials is relatively difficult, and polyurethane materials are easy to breed bacteria, are not light-resistant, and are relatively expensive
In addition, the fibers or fabrics made of polyurethane materials still have the following disadvantages: first, the hygroscopicity is relatively poor, the water absorption is not strong, and the anti-melting performance is not very good, and it is easy to absorb dust. due to
Second, the air permeability of polyurethane fabric is poor
The third is that the dyeing performance is poor, and it must be dyed with disperse dyes under high temperature conditions.
Fourth, because polyurethane has highly reactive and easily oxidized amino groups, it cannot be used in sanitary materials, so the use of products made of polyurethane materials is limited within a certain range
In summary, if traditional non-woven materials are used to prepare masks, due to their poor elasticity, they are easily broken when stretched to a large extent, and their air permeability is poor, which can easily cause users to have difficulty breathing and hold their breath. poor comfort

Abstract

The invention relates to the technical field of production of non-woven fabrics, in particular to a high-elasticity recovery spun-bonded non-woven fabric and a preparation method thereof. The non-woven fabric is prepared from the following raw materials in percentage by weight of 0-50% of polypropylene; 0-5% of a slipping agent; and the balance of thermoplastic elastomer. The preparation method comprises the steps of mixing the raw materials to form a mixture, and controlling the melt index of the mixture to be 55-100g / 10min, the gram weight of the non-woven fabric to be 10-200g / m <2>, the fiber diameter to be 10-30mu m, the elongation to be 80-1000% and the elastic recovery rate to be 55-95%. The invention further discloses a preparation method of the high-elasticity recovery spun-bondednon-woven fabric. The prepared non-woven fabric can be applied to the fields of medical treatment and public health and clothes, and the prepared non-woven fabric is good in elasticity, stability andbreathability, low in preparation cost, environmentally friendly and worthy of wide application and popularization.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric production, in particular to a highly elastic recovery spunbonded nonwoven fabric and a preparation method thereof. Background technique [0002] Spun-bonded non-woven technology is a non-woven production technology that uses polymer chips to be directly formed by extrusion melting, spinning, drawing, laying, and consolidation. Its production process is short and its production efficiency is high. It adopts large-scale production , has the advantage of low cost. In recent years, non-woven materials have continued to innovate in raw material processing and processing technology selection, product performance has been continuously improved, functions have become more diversified, and application fields have continued to expand. As a functional material, elastic nonwovens are widely used in the fields of medical care and clothing due to their excellent resilience properties, such as baby dia...
