Problems solved by technology

However, compared with cotton fabrics, ordinary polyester fabrics have poor hygroscopicity, moisture retention, and air permeability. They are easy to wear and feel stuffy, and have poor dyeing properties. The improvement of wearing comfort performance, key performance and visual aesthetics are particularly important
In recent years, with the continuous development of chemical fiber production and textile technology, great breakthroughs have been made in the comfort performance and dyeing of polyester chemical fiber. Ultra-fine denier modified polyester non-torque polyester false twist textured yarn, the fabric is flat and wrinkle-resistant, soft and smooth. , has good moisture absorption and perspiration performance and good dyeability, but it is difficult to produce in the original production state

Abstract

The invention relates to a method for manufacturing a superfine denier modified terylene torque-less false twist textured yarn and a special thread guide. The invention aims to solve the technical problem of providing a special thread guide and a manufacturing method using the thread guide. The thread guide comprises two thread rollers (5-3) on the thread guide shaft (5-1), wherein the two thread rollers can rotate independently, and a gap is reserved between the two thread rollers. The manufacturing method comprises the following steps that: two threads (11) get into a front thread-separation thread guide (1) of a first roller along the respective thread path; then the threads pass through a roller (2), a first hot box inlet thread guide (3), a first hot box (4), a special double-thread free-rotation thread guide (5), a special turning double-thread free-rotation thread guide (6), a cooling plate (7), a false twister (8), a second roller (9) and a network nozzle (10) in turn for stranding; and then the threads get into a second hot box (12) to perform heat shaping and obtain the product.

Description

technical field [0001] The invention relates to a method for manufacturing polyester chemical fiber filaments for textiles suitable for modified polyesters such as fine denier, ultra-fine denier, differential, and functional fibers, and hollow fibers with special-shaped cross-sections. Manufacturing method of polyester non-torque false-twist textured yarn and special yarn guide - double-filament free-rotating yarn guide. The invention can also be applied to the production of other differentiated and functionally modified polyester filaments without torque and false twist textured yarns. Background technique [0002] Polyester is a kind of chemical fiber clothing fabric raw material that is widely used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance and shape retention, and is suitable for outerwear. However, compared with cotton fabrics, ordinary polyester fabrics have poor hygroscopicity, moisture retention, and air permeability. ...
