生物基合成纤维在服装领域的应用现状及展望OA

Green and low-carbon is the inevitable trend of the development of the garment industry in the future.Bio-based synthetic fibers have shown broad application prospects due to their abundant resources,renewability,environmental protection and other excellent properties,and have become the key areas of green transformation in the garment industry.This article reviews the types and wearing properties of current mainstream bio-based synthetic fibers,elaborates on their development and application status in clothing fabrics and accessories,discusses the limitations of bio-based synthetic fibers in apparel products,and provides an in-depth analysis of their future development trends.It offers new insights and suggestions for advancing the sustainable development of bio-based synthetic fibers in the apparel industry. At present,the mainstream bio-based synthetic fibers mainly include bio-based polylactic acid(PLA),polybutylene succinate(PBS),bio-based poly(ethylene 2,5-furandicarboxylic acid)fiber(PEF),polyamide(PA),polytrimethylene terephthalate(PTT),polyhydroxyalkanoate(PHA)blends,etc.,which have good biocompatibility and other excellent wear properties.For example,PLA fibers have both biodegradability and antibacterial skin-friendly properties,and are especially suitable for close-fitting clothing and medical textiles.PEF fibers have significant potential in the field of high-performance clothing due to their high strength and heat resistance.Bio-based synthetic fibers have the characteristics of low energy consumption and low carbon emission during processing,which is in line with the concept of green and low carbon development.They can be applied in the field of textile and garment,and become an important material for the sustainable development of the garment industry. Bio-based synthetic fibers are mainly applied in the field of clothing,mainly including fabrics and accessories.The fabrics include short sleeves,outdoor sports clothing and underwear.For example,PLA fabrics are mostly used to make short sleeves,PA56 fabrics can be used to make outdoor sports clothing,while PLA and PHBV∕PLA blended fabrics can be used for underwear.The accessories include bonding linings,filling materials,etc.For example,PLA can be used as a bonding lining in shirt collars and cuffs to increase the stiffness and beauty of clothing.It can also be used as a down filling material in cotton clothing,and PA56 can be used in zipper belts. However,the application of bio-based synthetic fibers in clothing products still faces certain limitations.For example,the production cost of fibers is high;market competitiveness is slightly lower than traditional fiber;there is a lack of corresponding production technology and product standards.In the follow-up research and development process,bio-based synthetic fiber enterprises should focus on the improvement of production technology,reduce costs,and develop high-performance and functional wear products.For bio-based fabrics,garment enterprises also need to deal with research and development applications in the follow-up production and post-processing processes,and launch high-performance,high-function and sustainable wear products.
