Description

Multi-specification spinning structure of differential polyester filament yarn Technical Field The utility model relates to the technical field of chemical fiber spinning equipment, in particular to a multi-specification spinning structure of differential polyester filaments. Background With the continuous increase of the demands of textile industry for high-performance and multifunctional fiber materials, the differential polyester filaments are widely applied to the fields of high-end clothing fabrics, industrial textiles, medical materials and the like by virtue of the unique morphological structure and functionality (such as special-shaped cross section, fine denier, special surface properties and the like), so that the demands of the market for the specification diversity of the differential polyester filaments are increasingly increased. Patent publication No. CN222744449U, patent publication No. 2025-04-11 discloses a polyester filament spinning device, including a silk chamber, the top fixedly connected with pressure chamber of silk chamber, the inside fixedly connected with press of pressure chamber, the bottom fixedly connected with clamp plate of press, circular recess has been seted up at the top of silk chamber, the inside fixedly connected with filter plate of circular recess, a plurality of holes have been seted up to the inside of filter plate, a plurality of vertical grooves have been seted up to the inside of silk chamber, the inside sliding connection of vertical groove has the stopper, drives the rotation of transfer line through rotating the handle, and the transfer line reciprocates in the inside of vertical groove, promotes the handle and goes into the draw-in groove with the fixture block card, and the transfer line will not rotate to fix in the inside of vertical groove, realize adjusting from top to bottom and fixing of transfer line, adjust the height of heating leading wheel, thereby realize adapting to the tensile demand of different polyester filaments.
