Environment-friendly crimping device and method for recycled polyester staple fibers

Abstract

The invention belongs to the technical field of polyester fiber processing, and aims to solve the problems that an existing crimping device performs crimping operation on fibers only through pushing and extruding of a crimping wheel and a crimping knife, the fibers cannot be effectively heated, the crimping effect of the fibers is poor, the product quality is poor, the fibers cannot be cleaned, and adverse influence is caused to the quality of the product. The environment-friendly crimping devicecomprises a crimping roller assembly, and the crimping roller assembly is arranged between two sets of vertical plates; and a crimping cutter is arranged between the two sets of vertical plates. A cleaning assembly is arranged to remove impurities and dust on the surface of the polyester fibers, cleanliness of the polyester fiber is guaranteed, and improvement of the product quality is facilitated; and a steam preheating box is arranged to conduct steam heating on the polyester fibers, the subsequent crimping operation effect is remarkably improved, and the overall using effect of the crimping device is further improved.

Description

technical field [0001] The invention relates to the technical field of polyester fiber processing, in particular to an environment-friendly crimping device and method for regenerated polyester staple fibers. Background technique [0002] Polyester fiber, commonly known as polyester, is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, high strength and elastic recovery ability, and it is durable, wrinkle-resistant and non-ironing. In the production process of polyester fiber, polyester fiber generally needs to be processed. Curling operation, the crimping operation of polyester fiber is completed by crimping device; [0003] A Chinese patent application number 202020996977.4 discloses a crimping machine for the production of composite fiber fabrics, including a frame and upper ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an environment-friendly crimping device and method for regenerated polyester staple fibers, by setting cleaning components to remove impurities and dust on the surface of polyester fibers, ensuring the cleanliness of polyester fibers, and helping to improve product quality. The stretching assembly is set to apply an upward pulling force to the cleaning assembly, so that the polyester fiber is in a tensioned state, which is helpful for the conveying of the polyester fiber and the subsequent crimping operation, and the steam heating of the polyester fiber is carried out by setting a steam preheating box , which significantly improves the effect of the subsequent crimping operation. By sending out the steam in the steam preheating box and making the crimping roller fully absorb the heat in the steam to increase its own temperature, it helps to improve the crimping effect on polyester fibers and reduce The waste of energy is relatively energy-saving and environmentally friendly. By setting up an exhaust fan, the continuous output of steam and the cleaning operation of the cleaning components can be realized at the same time, which reduces equipment costs and improves the overall use effect of the crimping device. The curling operation of the fiber is carried out by pushing and squeezing the curling knife, the fiber cannot be heated, the curling effect of the fiber is not good, the product quality needs to be improved, and the fiber cannot be cleaned, and the impurities and dust on the fiber surface will also affect the product. issues that adversely affect the quality of
