Embodiment 1

[0011] A production method of ultra-fine polyester low-elastic yarn, using polyester filament as raw material, sequentially passing through a pre-netting device, a shredder, a first feeding roller, a first heating box, a cooling plate, a false twister, and a second Feed rollers, webs, second hot boxes, third rollers, thread detectors, oiling systems, winding. The second hot box adopts a low-temperature biphenyl hot box, and the temperature is 90-110 ° C. The first roller and the second roller are all of godet type, without top rollers, and the thread is wound on the godet for 4- 5 turns, so as to minimize the wear on the thread to ensure the quality of the thread. The second overfeed rate is 3.0%, and the third overfeed rate is 3.5%.

Abstract

The invention discloses a production method of superfine denier polyester low stretch yarns. The method is characterized by comprising the following steps: feeding polyester filament yarns serving as a raw material through a pre-collector, a yarn cutter, a first feeding roller, a first hot box, a cooling plate, a false twister, a second feeding roller, a collector, a second hot box, a third roller, a yarn detector and an oil applying system in sequence; winding. Superfine denier polyester low stretch yarns produced by using the production method of the superfine denier polyester low stretch yarns have good performance and stable quality, and are much superior to the existing commercially-available polyester low stretch yarns in quality; the breaking strength is 3.7cN/dt, and the elongation at break is 21 percent.

Description

technical field [0001] The invention relates to a production method of superfine denier polyester low elastic yarn, which belongs to the technical field of chemical fiber. Background technique [0002] With the further diversification of the chemical fiber market, functional fibers are also increasingly concerned, and ultra-fine denier and low-elasticity yarns are sought after by people for their excellent performance, but the production process for producing ultra-fine denier and low-elasticity yarns in the prior art is not yet Mature. Contents of the invention [0003] The invention provides a method for producing superfine denier low elastic yarn in order to solve the deficiencies in the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A production method of superfine denier polyester low elastic yarn, characterized in that it comprises the following steps: taking polyester filament as raw mat...
