Problems solved by technology

[0002] The current high-speed polyester staple fiber sewing thread is produced by dyeing the original white blank thread. The original white blank thread is a white polyester staple fiber raw material with a linear density of 1.2D and a length of 38mm. On the one hand, the pine tube and dyeing process are required during processing, which virtually increases the production links; on the other hand, during the subsequent dyeing process, a lot of electricity is wasted and a large amount of waste water is generated, and the production process is not environmentally friendly.

Embodiment 1

[0032] A beige regenerated dope dyed high-speed polyester staple fiber sewing thread is prepared by the following method:

[0033] (1) After the recovered mineral water bottle is crushed, washed and dried, mineral water bottle fragments are obtained, and the beige color masterbatch after adding is mixed evenly, and then added into a screw extruder to be heated and melted into a melt; the dried The drying time is 10 to 12 hours, the drying temperature is ≤135°C, and the water content of the mineral water bottle fragments and the masterbatch is ≤120ppm after drying; the mass ratio of the mineral water bottle fragments to the masterbatch is 99:1;

[0034] (2) The melt is spun at a high speed through a filter, a metering pump, and a spinneret assembly to generate primary fibers; the specification of the filter is 200 mesh to 300 mesh; the spinneret assembly uses a filter screen of 200 mesh to 300 mesh , sea sand is assembled according to 3.0-4.0kg; the spinning temperature of the ...

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.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a recycled dope-colored high-speed polyester staple fiber sewing thread and a preparation method thereof. Background technique [0002] The current high-speed polyester staple fiber sewing thread is produced by dyeing the original white blank thread. The original white blank thread is a white polyester staple fiber raw material with a linear density of 1.2D and a length of 38mm. On the one hand, loose tubes and dyeing processes are required during processing, which virtually increases the number of production links; on the other hand, during subsequent dyeing, a large amount of electricity is wasted and a large amount of waste water is generated, and the production process is not environmentally friendly. Contents of the invention [0003] The purpose of the present invention is to provide a recycled dope dyed high-speed polyester staple fiber sewing thread and its preparati...
