Abstract
The invention belongs to the field of spinning, and particularly relates to a regenerated stock solution colored high-speed polyester staple fiber sewing thread and a preparation method thereof. The regenerated stock solution colored high-speed polyester staple fiber sewing thread is prepared with regenerated colored fiber as the raw material through a spinning technology after recovered mineral water bottles are smashed and mixed with color master batch to obtain regenerated colored fiber through melt blending and melt high-speed spinning. After recovered mineral water bottles serve as the raw material and are mixed with color master batch, fiber can be directly processed into colored fiber without being dyed, lots of water and electricity needing to be consumed during dyeing are saved, and social benefits are remarkable; meanwhile, reels do not need to be loosened in the spinning technology, one procedure is omitted, and production cost is reduced; meanwhile, the spinning technology is optimized, and the use range of fiber raw material is widened; the hairiness rate and breakage rate are decreased, and therefore the prepared regenerated stock solution colored high-speed polyester staple fiber sewing thread is high in sewability and more suitable for high-speed sewing.
