Problems solved by technology

However, most of the non-woven fabrics currently on the market are mostly made of polypropylene raw materials. If the waste non-woven fabrics are not incinerated, it will inevitably form an important source of pollution in the form of waste residue and wastewater; if the waste non-woven fabrics are treated by incineration, serious air pollution

Abstract

The invention discloses bio-based non-woven fabrics and a preparation method thereof. The non-woven fabrics is prepared from the following components in ratio by mass part: 30-60 parts of polypropylene, 25-55 parts of starch, 5-10 parts of plasticizer, 0.5-2 parts of polypropylene flow promoter, and 0.5-5 parts of filler. The preparation method is as follows: firstly, the polypropylene, the starch, the plasticizer, the polypropylene flow promoter and the filler are prepared into a required bio-based material as per specific production process, and then the bio-based material is processed for the second time by virtue of the spunbonding technology so as to form the bio-based non-woven fabrics. According to the method, the thermoplastic starch and polypropylene resin blending system are adopted, so that the thermoplastic starch can be dispersed in the polypropylene matrix uniformly; the plasticizer is used, so that the starch has the thermoplasticity, and the processibility of the starch and the compatibility of the starch with the polypropylene resin are improved; and moreover, the polypropylene flow promoter is used, so that the melt flow rate of the polypropylene / thermoplastic starch is improved and thus the spinnability of the material is improved.

Description

technical field [0001] The invention relates to a preparation method of bio-based non-woven fabric, which belongs to the technical field of textile and polymer materials. Background technique [0002] Non-woven fabric (English name: Non Woven), also known as non-woven fabric, is a kind of fabric formed without spinning and weaving. It just oriented or randomly arranged short textile fibers or filaments to form a web structure, and then used Reinforced by mechanical, thermal bonding or chemical methods. To put it simply: it is not interwoven and knitted together by one yarn, but the fibers are directly bonded together through physical methods. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. It is widely used in many fields such as clothing lining, medical accessories, industrial filter lining, thermal in...
