Discussion on Degradable Non-Woven Materials

Some chemical fiber of textile materials are difficult to degrade and have become new sources of pollution. Textiles made of biodegradable fibers can be decomposed into carbon dioxide and water under the action of microorganisms, which is harmless to the environment; biodegradable fibers are also used in medical treatment, gardening, and construction because of their good performance and outstanding biocompatibility. It has been widely used in other fields. Biodegradable nonwoven fabric is a nonwoven fabric made of biodegradable fibers, which can be slowly decomposed under the action of microorganisms in the natural environment.

Polylactic acid fiber uses renewable corn, wheat and other starches as raw materials, fermented into lactic acid, and then polymerized and spun. The waste is decomposed into carbon dioxide and water under the action of microorganisms in soil or water. It is a completely biodegradable fiber, which uses lactic acid as its basic structure. Lactic acid is a natural compound commonly found in animals, plants and microorganisms. Polylactic acid is a kind of thermoplastic polymer. Due to the large amount of non-crystalline structure in the internal structure of its fibers, it will biodegrade quickly in the presence of water, bacteria and oxygen. At present, the non-woven fabrics produced by it are widely used.

With the rapid development of human society and economy, protecting the environment and preventing pollution have become the consensus of all countries. Biodegradable nonwovens are a new type of textiles, which are compatible with the environment. The combination of natural biopolymer materials and non-woven technology has become an important direction for the development of the non-woven industry.
