Why do many industries use polylactic acid fibers

     Polylactic acid fiber is a biodegradable synthetic fiber that is used in many industries, mainly due to its unique advantages in biocompatibility, physical properties, processing performance, and environmental protection. The following is a specific introduction:
1. Medical industry
     Good biocompatibility: Polylactic acid fiber has good biocompatibility and does not cause immune or inflammatory reactions in the human body. It can bind well with human tissues and can be used to manufacture medical products such as sutures, tissue engineering scaffolds, drug delivery carriers, etc.
     Degradable absorption: In the human body, polylactic acid fibers can gradually degrade into carbon dioxide and water over a certain period of time, which are metabolized and excreted by the body without the need for secondary surgery to remove them, reducing the pain and infection risk of patients. They are particularly suitable for short-term implantation of medical supplies in the body.
2. Textile industry
     Natural fiber like feel: Polylactic acid fiber has a soft feel and good moisture absorption, making it comfortable to wear and comparable to natural fibers such as cotton and wool. It can provide consumers with a comfortable wearing experience and is commonly used in the production of clothing, home textiles, and other products.
     UV resistance: It also has good UV resistance, which can protect the skin from sunburn. Clothing made from it has a certain sun protection function, increasing the functionality and added value of the product.
     Dyeability: Polylactic acid fibers are easy to dye and can present a variety of colors, meeting the textile industry's demand for color and fashion, enabling designers to create various styles of textiles.
3. Packaging industry
     Environmentally friendly and biodegradable: With the increasing awareness of environmental protection, the environmental problems caused by traditional plastic packaging are becoming increasingly serious. Polylactic acid fiber can degrade in natural environments and effectively reduce white pollution, meeting environmental requirements. Therefore, it is widely used in food packaging, disposable tableware, shopping bags and other fields.
     Good barrier performance: Polylactic acid fibers have certain barrier properties against oxygen and water vapor, which can effectively maintain the freshness and quality of the contents in the packaging, extend the shelf life of the product, and are suitable for packaging various foods, drugs, and other items that require certain storage conditions.
4. Agricultural industry
     Application of agricultural film: Polylactic acid fiber can be made into agricultural film, which has good insulation, moisture retention and light transmission properties, and can promote the growth of crops. Moreover, after use, agricultural film can naturally degrade in the soil and will not remain in the soil like traditional agricultural film, affecting soil structure and crop growth, which is beneficial for the sustainable development of agriculture.
     Seedling bowl: The seedling bowl made of polylactic acid fiber can provide a good growth environment for seedlings. It can be directly buried in the soil during transplantation without the need to remove it, reducing damage to the seedling roots and improving the survival rate of seedlings.
5. Other industries
     Filter material: Polylactic acid fiber has excellent filtration performance and can be used to manufacture air and water filtration materials. It can effectively remove dust, pollen, and impurities in the air and water, improving air and water quality.
     3D printing materials: Polylactic acid fibers have good thermal stability and formability, making them suitable as 3D printing materials. They can print various complex shaped parts and models, and have broad application prospects in manufacturing, design, and other fields.
