In a significant milestone for the textile industry's green transition, a joint research team has announced the successful development of a modified polylactic acid (PLA) fiber that matches or exceeds traditional polyester in key performance metrics.
Technical Breakthrough
The new modified PLA fiber achieves a breaking strength of 4.8cN/dtex (comparable to polyester's 4.5-5.0cN/dtex), a melting point of 215°C (45°C higher than conventional PLA), and disperse dye uptake rates exceeding 92% — approaching polyester levels. These advances were achieved through innovative copolymerization and nano-reinforcement technologies.
Commercialization Prospects
The technology has completed pilot-scale validation with an annual capacity of 500 tons. Industrial-scale production of 10,000+ tons is expected by the first half of 2027. Current production costs are approximately 2.5x that of polyester, projected to fall below 1.5x within 3-5 years as scale increases.
Market Applications
Industry experts see initial commercial applications in sportswear (where consumer acceptance of eco-materials is highest), home textiles, and industrial textiles. The global biodegradable fiber market is projected to reach $12 billion by 2030, growing at over 15% CAGR.
