Problems solved by technology

However, the starch molecular chain contains a large number of hydroxyl groups, which are easy to form hydrogen bonds inside and outside the molecular chain, so it is insoluble, infusible, and has poor water resistance. It is easy to absorb water when exposed to water or stored in humid air for a long time, affecting its stability. sex

Abstract

The invention provides a preparation method of multilayer anti-tensile non-woven fabric. The preparation method includes the steps of preparation of a film; preparation of fiber layers, wherein long fibers are prepared into the net-shaped long fiber layer, and short fibers are prepared into the short fiber layer; fiber hardening; preparation of glue; synthesis of the non-woven fabric, wherein the long fiber layer is attached to the upper portion of the film, the short fiber layer is attached to the lower portion of the film, the joints are coated with the glue, and through hot pressing, synthesis is completed. The preparation method has the advantages that an adopted starch source is rich, price is low, and environment friendliness is achieved; the prepared non-woven fabric is high in strength, low in production cost, biodegradable, long in storage time and resistant to high temperature and water, the white pollution problem can be effectively relieved, the service life is prolonged, white pollution is reduced, and the environment is protected.

Description

Technical field: [0001] The invention relates to the technical field of non-woven fabric production, in particular to a method for preparing a multi-layer stretch-resistant non-woven fabric. Background technique: [0002] With the vigorous development of the plastic industry, the environmental pollution caused by waste plastic film garbage is becoming more and more serious, and white pollution has become a global environmental problem. Therefore, people must intensify their efforts to develop biodegradable plastic films to control the environmental pollution caused by plastic waste. [0003] Non-woven fabrics occupy a part of the film market, and their strength is stronger than that of films, but their lifespan is short, and under direct sunlight, non-woven fabrics become brittle for a long time. [0004] Starch is a natural polymer material with abundant sources and low price. It is also an inexhaustible renewable resource. It can be biodegraded under various environmental...
