Embodiment 1

[0023] Example 1: Take the device installed on the FA506 ring spinning frame to spin pure cotton combed 14.6tex yarn as an example, wherein the raw cotton is 100% Xinjiang long-staple cotton.

[0024] The parameters of each process in the production process are as follows:

[0025] (1) Blowing and carding process: the nep growth rate of banquet cotton is 82% higher than that of raw cotton. The speed of the sawtooth roller main cleaning roller is 720r / min, the speed of the opening roller of the feeding box is 900r / min, the speed of the cylinder of the carding machine is 425r / min, the ratio of the linear speed of the cylinder to the licker-in roller is 2.7, and the speed of the cover plate is 280m / min , the distance between the face plate and the licker-in roller is 0.75mm, the distance between the cylinder and the doffer is 0.1mm, the distance between the cylinder and the cover plate is 0.21, 0.175, 0.18, 0.18, 0.2mm, the distance between the cylinder and the rear fixed cover p...

Embodiment 2

[0033] Example 2: Take the installation of this device on the FA506 ring spinning frame to spin pure cotton combed 9.7ex yarn as an example, wherein the raw cotton is 100% Xinjiang long-staple cotton.

[0034] The parameters of each process in the production process are as follows:

[0035] (1) Blowing and carding process: the nep growth rate of banquet cotton is 80% higher than that of raw cotton, the speed of the catching machine is 1180r / min, the cotton opening adopts a double-axis flow opener, the speed of the beating is 490r / min, and the cleaning machine The speed of the sawtooth roller main cleaning roller is 690r / min, the speed of the opening roller of the feeding box is 840r / min, the speed of the cylinder of the carding machine is 395r / min, the ratio of the linear speed of the cylinder to the licker-in roller is 2.4, and the speed of the cover plate is 265m / min , the distance between the face plate and the licker-in roller is 0.70mm, the distance between the cylinder a...

Abstract

The invention discloses a large torque spinning yarn production method which comprises a blowing-carding process, a combing process, a drawing process, a roving process, and a spun yarn process. A resistance twister is further arranged between a front roller jaw and a yarn guide hook of a spinning machine. Two yarn moving paths between the front roller jaw and the resistance twister are respectively and further provided with a twist degree device. According to the method, simultaneous feeding of large distance double rough yarns is adopted in the spun yarn process, and the resistance twister is further arranged close to the yarn guide device and between the front roller jaw and the yarn guide hook, so that a twisting point is moved downward; moreover, the twist degree devices are further arranged between the front roller jaw and the resistance twister, so that resultant yarn hairiness is greatly reduced, strength is improved, and the effect of tight yarn is achieved. On the same condition, yarn spun according to the method is reduced by 65-80% than common ring spinning in harmful hairiness which is 3mm or more, and is improved by 5-8% in strength.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a production method of high-torque spinning yarn. Background technique [0002] Ring spinning, which achieves twisting through spindle rotation, is the most traditional spinning method, and it is also the most widely used and most common spinning method in the market. The technology is very mature. New spinning technologies, such as rotor spinning, air-jet spinning, etc., especially air-jet spinning, have completely changed the twisting mechanism of ring spinning by using high-speed swirling airflow to make fiber bundles false-twisted and wrapped into yarns, but these new spinning methods There is still no substitute for ring spinning in terms of raw material availability and overall yarn quality. Therefore, ring spinning is still the most important method of spun yarn production. [0003] However, ring spinning is not perfect. Due to the existence of the twisting tri...
