Abstract

The invention relates to a production system for black polyester staple fibers. The system comprises a polyester (PET) chip feed device, a carbon black feed device, a dispersant feed device, a solid-phase additive feed device and a co-rotating twin-screw extruder (5), wherein the material outlet of the co-rotating twin-screw extruder (5) is connected with a main melt pipeline (6); a booster pump unit (61), a melt dynamic mixer (62), a melt filter (63) and a melt cooler (64) are sequentially arranged on the main melt pipeline (6) from front to back; the tail end of the main melt pipeline (6) is connected with a polyester fiber spinning unit (8) through a melt static mixer and a distribution pipe (7); and a raw white polyester melt feed pipeline (9) is connected between the booster pump unit (61) and the melt dynamic mixer (62) on the main melt pipeline (6). The production system has the advantages that the spinning production and product quality can be guaranteed, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a production system of black polyester staple fiber. Background technique [0002] Chemical fibers have always been mainly produced in the form of white fibers, which are bleached and dyed into various colors and finally become colorful textiles. Due to the large environmental pollution caused by the bleaching and dyeing process, it has become a trend to produce colored fibers through pre-spinning coloring in the chemical fiber production process to greatly reduce pollution. In particular, black polyester staple fiber has a large demand and stable color requirements, and is a green product with great development prospects. At present, the production of this product is produced by mixing carbon black and PET in the masterbatch production plant to produce black masterbatch, and then adding black masterbatch to the spinning process during the spinning process. In this process route, there is a large amount of masterbatch added, ...
