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 discloses a method for preparing high-temperature-resistant non-woven fabric. The method includes the steps of preparing a film; preparing a fiber layer; preparing a net-shaped long-fiber layer; preparing a short-fiber layer from short fibers; carrying out fiber hardening; preparing glue; attaching the long-fiber layer to the upper portion of the film through the glue; attaching the short-fiber layer to the lower portion of the film through the glue; completing combining through hot pressing. The method has the advantages that the source of adopted starch is rich, low in price and environmentally friendly; the prepared non-woven fabric is high in intensity, low in production cost and biodegradable, and the white pollution problem can be effectively solved; the non-woven fabric is long in preserving time, resistant to high temperature and waterproof, 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 nonwoven fabric production, in particular to a preparation method of high temperature resistant nonwoven 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 condi...
