Plant composite fiber, plant fiber composite and preparation method of plant fiber composite

Abstract

The invention belongs to the field of new materials and provides a plant composite fiber, a plant fiber composite and a preparation method of the plant fiber composite. The plant composite fiber is mainly prepared from plant fiber and low-melting-point polyester fiber through mixing with a spunlace or needle punching technology, wherein the melting point of the low-melting-point polyester fiber is 60-200 DEG C. The plant fiber composite has the advantages of being high in strength, low in weight, stable in physical performance, not easy to damage, capable of being recycled and the like. The plant fiber composite prepared from the plant fiber composite has the advantages that the surface texture is natural and plain, the color is bright, the texture is novel, adhesives are not contained, recycling is realized and the like. The plant fiber composite can be widely applied to fields such as packaging products, artware, daily necessities and the like.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a plant composite fiber, a plant fiber composite material and a preparation method of the plant fiber composite material. Background technique [0002] With the development of modern industry and social economy, a serious "public nuisance" has appeared in the society, which is hundreds of millions of garbage. These wastes not only consume the resources of the earth, but most of them are non-degradable wastes, which are difficult to reuse, causing serious public hazards to the ecological environment, and endangering people's health. It has become a major obstacle to the development of human society. . [0003] Plant fiber materials are derived from crop stalks and rapidly regenerating plants. They are inexhaustible renewable resources in nature. They are the development and utilization of waste or renewable resources. They are applications that turn waste into treasure. save resourc...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there are also some articles made of plant fibers, such as palm mattresses, plant fiber boards and other articles, but these products need to be added in the manufacturing process. Adhesives often contain formaldehyde and other harmful substances in these adhesives. Substances that are harmful to the human body, seriously pollute the indoor air, and are harmful to human health

In addition, the plant fiber content of these items labeled as plant fiber is often not high, and the plant fiber content of some items is even below 5%, which is just a gimmick for advertising and cannot achieve a good natural degradation effect

At the same time, the plasticity of this bonded article is not strong, and it is impossible to manufacture articles with complex shapes. Therefore, the application is not extensive.
