Among many functional fibers, elastic fiber plays an irreplaceable role in comfort and shape retention because it can give good contact feeling to the human body. Therefore, endowing certain flexibility to textile fabrics has become an inevitable development tendency for textiles for apparels.
In 1959, after DuPont introduced large-scale Lycra products, elastic fibers caused widespread concern. In the 1990s, with the expansion of the function of the following link (such as the development of spandex core-spun technology), spandex stretch fabrics began a new round of production climax. The use of spandex increased rapidly, and many large foreign companies have also developed their own unique spandex production technology, greatly improving the quality of its products, such as Taekwang from South Korea and Hyosung etc. At the same time, the melt-spinning technology also made breakthrough progress. Due to its low investment cost and environmental advantages, it has developed rapidly. At present, the global spandex capacity has reached 1.12 million tons, including Hyosung from South Korea, Ruyi from China (Invista acquired spandex business from DuPont in 2004, and this business has been acquired by Ruyi), and Huafon, which ranked the top three in view of capacity.
