Research and development of biodegradable fiber yarns

Degradable fiber yarn is an environmentally friendly textile material made of degradable fibers that can be decomposed by microorganisms under certain conditions, thereby reducing the impact on the environment. There are many types of degradable fibers, including but not limited to the following:

1. Polylactic acid fiber (PLA): Polylactic acid polymer made from renewable resources such as corn starch fermentation, has good biodegradability.

2. Polyhydroxyalkanoate (PHA): a type of natural polymer material synthesized by microorganisms and has good biodegradability.

3. Cellulose fiber: such as bamboo fiber, hemp fiber, etc. These natural fibers can be decomposed by microorganisms in the natural environment.

4. Protein fiber: Such as soybean protein fiber, silkworm protein fiber, etc. These fibers are derived from protein and can also be decomposed in the natural environment.

5. Polyester fiber: Although traditional polyester fiber is not easily degraded, some new polyester fibers, such as polybutylene succinate (PBAT) and polycaprolactone (PCL), have better biodegradability. sex.

Biodegradable fiber yarns are widely used in clothing, home textiles, medical supplies and other fields. Not only do they help reduce plastic waste, they also reduce the environmental burden of textile production and disposal. With the improvement of environmental awareness and the development of science and technology, the application prospects of degradable fiber yarns are becoming more and more broad.
