Problems solved by technology

Many of the above factors increase the broken ends of the spun yarn, and the difficulty of jointing increases the difficulty of production
In the prior art, pure spinning of cotton fibers cannot obtain strong twisted yarns with fine yarns and good quality, especially it is difficult to obtain twisted yarns with good spun yarn strength.

Embodiment 1

[0031] The present embodiment proposes a kind of production method of twisted yarn, comprises the following steps:

[0032] Cotton fibers are used as raw materials to be processed in turn through the cleaning process, carding process, combing process, drawing process, roving process, spun yarn process and winding process; in the cotton fiber, calculated according to the mass percentage, by 80% Xinjiang fine-staple cotton and 20% Brazilian cotton;

[0033] In the cleaning and carding process, the feeding plate and the licker-in rollers have a spacing of 12 inches, and the cylinder and the cover plate have a 5-point spacing of 8 inches × 7 inches × 7 inches × 7 inches × 8 inches. The entrance distance between the roller and the small drain bottom is 8mm, and the exit distance is 2mm; the carding dry weight is 19.2g / 5m;

[0034] In the combing process, the combed dry weight is quantitatively 18.9g / 5m, and the combed noil rate is controlled within 15%;

[0035] Wherein, the draw...

Embodiment 2

[0040] The production method of this embodiment is basically the same as that of Example 1, except that the twist direction in the spinning process is S twist, and JC9.7tex single yarn with tight S twist and strong twist is produced, and the single yarn is high-count strong twist yarn.

Embodiment 3

[0042] The present embodiment proposes a kind of production method of twisted yarn, comprises the following steps:

[0043]Cotton fibers are used as raw materials to be processed in turn through the cleaning process, carding process, combing process, drawing process, roving process, spun yarn process and winding process; in the cotton fiber, calculated according to the mass percentage, by 80% Xinjiang fine-staple cotton and 20% Xinjiang long-staple cotton;

[0044] In the cleaning and carding process, the feeding plate and the licker-in rollers have a spacing of 12 inches, and the cylinder and the cover plate have a 5-point spacing of 8 inches × 7 inches × 7 inches × 7 inches × 8 inches. The entrance distance between the roller and the small drain bottom is 8mm, and the exit distance is 2mm; the carding dry weight is 19.2g / 5m;

[0045] In the combing process, the dry weight of combed Xinjiang fine-staple cotton is quantitatively 19g / 5m, and the dry weight of combed Xinjiang l...

Abstract

The invention discloses twisted yarn and a production method thereof, and belongs to the technical field of spinning. The production method of the twisted yarn comprises the following steps that cotton fibers serve as raw materials and are sequentially processed by a blowing procedure, a blowing-carding procedure, a combing procedure, a drawing procedure, a roving procedure, a spinning procedure and a spooling procedure to prepare the twisted yarn. The drawing procedure comprises the following step of carrying out twice combination, wherein 8 yarns are combined at the first time, and the dry weight ration is 15.2-18.6 g / 5 m; 6-8 yarns are combined at the second time, and the dry weight ration is 15-18.5 g / 5 m; and the spun yarn twist in the spinning procedure is 200-230 twists / 10 cm. The invention also discloses the twisted yarn obtained by the production method. The count of the twisted yarn is 60-80, and the strength of the twisted yarn can reach up to 178 CN.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a twisted yarn and a production method thereof. Background technique [0002] Strong twist yarn is mainly used for weaving weft yarn, which can make the cloth surface wrinkled in a unique style. Strong twist yarn has good dimensional stability, and the washing shrinkage rate is small. Clothes or other textiles made of this fabric do not need to worry about shrinkage after washing. Strong twisted yarn has good luster, very smooth and comfortable hand feeling, and has good verticality. It is very good for making underwear and will not cause damage to the skin. It is a healthy and green textile. [0003] The pre-spinning production process and quality control of strong twisted yarn are basically the same as those of conventional yarns, except that the twist coefficient of spun yarn exceeds the critical twist coefficient of the yarn, and the yarn strength is lower than that of conv...
