Polyurethane fiber coating device used on elasticizer

Abstract

The invention discloses a polyurethane fiber coating device used on an elasticizer which has low production cost and can directly finish composite coating of fiber filament on the elasticizer. The device comprises a proto-filament frame, a first guide pressing arm, a proto-filament roller, a molding frame, a pedestrian pedal and a stand, wherein the proto-filament roller is matched with the first guide pressing arm; a heating box is arranged on an input part for synthetic fiber filament between the molding frame and the stand; the stand is sequentially provided with a twister, a second guide pressing arm, a first tension roller, a polyurethane fiber drum, a traction roller, a composite filament deformation air spout, a third guide pressing arm and a second tension roller from top to bottom; the first tension roller is matched with the second guide pressing arm; and the second tension roller is matched with the third guide pressing arm.

Description

technical field [0001] The invention relates to a textile equipment, in particular to a spandex covering device used on a texturing machine. Background technique [0002] At present, the composite coating of synthetic fibers and their filaments is realized on two kinds of equipment, the texturing machine and the composite coating machine. For example, polyester filaments or polyamide filaments are coated with spandex yarns, and the polyester filaments or polyamide filaments are firstly processed on the texturing machine, and then compounded with spandex yarns on the coating machine to form coated yarns. . Due to the use of two types of equipment for processing, the equipment investment is large, the site occupation is large, the unit labor is large, the energy consumption is high, the production cycle is long, and the economic benefit is low. At the same time, the fiber processing process is long and the friction times are many. Intrinsic quality indicators such as strengt...

Problems solved by technology

Due to the use of two types of equipment for processing, the equipment investment is large, the site occupation is large, the unit labor is large, the energy consumption is high, the production cycle is long, and the economic benefit is low. At the same time, the fiber processing process is long and the friction times are many. Intrinsic quality indicators such as strength are affected to varying degrees, and the quality of the produced covered yarn is also unstable, which affects the quality of the finished fabric
