Polylactic acid fiber belongs to bio based biodegradable synthetic fibers. With its weak acidity, skin affinity, antibacterial and mite inhibiting properties, excellent biocompatibility, low smoke and flame retardant properties, and industrial composting and degradation capabilities, it can be spun pure or blended with cotton, lyocell, wool, viscose and other fibers. It is widely used in clothing and home textiles, disposable hygiene care, medical materials, agriculture, forestry and horticulture, industrial textiles, environmental packaging and other fields.
1、 Clothing and textile products
Based on its excellent moisture conductivity, breathability, low sensitivity, skin friendly, antibacterial and deodorizing properties, it is suitable for close fitting knitted and woven fabrics. Mainly includes categories such as baby clothing, close fitting underwear, home wear, yoga and fitness clothing, sports functional fabrics, casual shirts, school uniforms, etc; Blended technology is often used to compensate for heat-resistant shortcomings, improve fabric size stability and processing adaptability, and adapt to the development direction of green textiles.
2、 Home textiles and indoor soft furnishings products
Includes bedding fabrics such as a four piece set, mattress surface layer, pillowcase, etc; Three dimensional curled polylactic acid short fibers can be used as filling materials for pillow cores, quilts, pillows, and plush toys, with advantages of warmth retention, antibacterial and mite prevention; At the same time, soft decorative fabrics such as curtains and wall coverings can be made, with low smoke emission during combustion and good flame retardant safety characteristics.
3、 Disposable hygiene and beauty non-woven products
As one of the mainstream application directions of this fiber, it is processed by nonwoven processes such as spunbonded, hot rolled, needle punched, etc., and can be used for diaper surface, menstrual care product surface, care pad, disposable facial towel, makeup removal cotton, facial mask base cloth, dry and wet towel base material, disposable protective mask and other products. It has soft touch, high biological safety, and can enter the composting system for degradation treatment after being discarded.
4、 Medical absorbable materials
Based on excellent biocompatibility, the degradation product is endogenous lactic acid in the human body, which is non-toxic and accumulates. Absorbable surgical sutures, wound dressings, anti adhesion films, soft tissue repair scaffolds, medical bandages, surgical drapes, isolation gowns, etc. can be prepared. Some specifications can be adapted to the ethylene oxide sterilization process, and the mechanical attenuation period can be adjusted according to the formula to match the in vivo absorption period.
5、 Industrial textiles for agriculture, forestry and horticulture
This is a green solution to reduce agricultural film pollution, and the product can gradually degrade in the soil environment after the end of its service life without the need for recycling. It mainly includes biodegradable horticultural weed proof cloth, seedling nutrition bowl, seedling wrapping bandage, crop insulation cover cloth, fruit protection bag, seed cultivation base cloth, etc., which also have functions of moisture preservation, grass suppression, and protection, and are suitable for ecological planting scenarios.
6、 Environmentally friendly packaging and filtering materials
Can be processed into biodegradable non-woven fabric for use in product dust bags, gift liners, food soft packaging liners, and tea bag filter materials; Air and liquid filtration substrates can also be prepared to meet the environmental requirements of compostable disposal after filtration use, reducing solid waste pressure.
7、 Automotive interiors and other industrial products
Used for car roof, interior sound insulation filling, carpet substrate, to achieve low smoke, lightweight, environmentally friendly and odorless characteristics; It can also be used in geotechnical protection, geotechnical reinforcement short fibers and other scenarios.
