Problems solved by technology

Although this invention can improve the yarn-forming performance of rotor spinning, it can spin some textile fibers with high rigidity (such as ramie fiber) and high elasticity (such as wool) into yarn, and the quality of the spun yarn is better, but due to the The invention is to add a heat and humidity treatment device and a steam channel to the rotor spinning machine. The cost of equipment transformation is high, and steam with a higher temperature must be provided during work. The steam consumption is large, and the spinning cost is high. The rotor spinning machine is long-term. In the steam, the corrosion is large, the rotor spinning machine is easily damaged, and the service life is shortened

Embodiment 1

[0047] For the convenience of description, this embodiment provides a manufacturing process of cooked bars.

[0048] 1. Use a forklift to cross-stack the cotton bales in proportion to the cotton path of the plucking machine, and leave a return position in the center of the cotton bales. The average length of viscose staple fiber 1.2D is 32mm, the length deviation rate is ±0.3%, the rate of ultra-long fiber is 0.1%, the double-length fiber is 0.5mg / 100g, the defect is 2.1mg / 100g, and the dosage is 35%; the length of viscose staple fiber is 1.5D The average is 32mm, the length deviation rate is ±0.3%, the ultra-long fiber rate is 0.1%, the double-length fiber is 0.5mg / 100g, the defect is 2.1mg / 100g, and the dosage is 65%.

[0049] 2. The catching machine grabs the cotton bundle (block), and adds a roller with reverse claws on both sides of the cotton grabbing arm, such as figure 1 It makes the shape of the cotton bundle grabbed by the plucking machine into a spherical shape, wh...

Embodiment 2

[0060] This embodiment is basically the same as Embodiment 1, the difference is: the rotating speed of the opening roller 2 is 8500r / min; the rotating speed of the rotor 3 is 60000r / min, and the negative pressure of the process is 6.8kpa; the twist of the yarn after twisting is 430 twists / m; the linear density of cooked strips is 420g / m; the dry uniformity CV% value of cooked strips 13 is 2.71; the arc-shaped flanging cotton inlet 10 is 15mm wide and 12mm high, and the curved cotton exit 14 is 10mm wide and 4mm high; The diameter of the zigzag combing roller is 64mm, and the number of combing teeth is 12 rows; the combining ratio is 100 times; the diameter of the rotor 3 is 40mm; is 30°, and the winding speed is 200m / min.

[0061] The quality of the 10 yarns produced in this embodiment reaches: the average breaking strength is 784cN, the breaking strength is 14.2cN / tex, and the evenness CVm% value is 10.5.

Embodiment 3

[0063] This embodiment is basically the same as Embodiment 1, and the difference is that the rotating speed of the opening roller 2 is 8500~8800r / min; the rotating speed of the rotor 3 is 62000r / min, and the process negative pressure is 6.85kpa; the twist of the yarn after twisting is 435 twists / m; cooked strip 13 linear density is 410g / m; cooked strip 13 dry uniformity CV% value is 2.73; arc-shaped flanging cotton inlet 10 is 16mm wide and 11.5mm high, and arc-shaped cotton outlet 14 is 9.5mm wide mm, height 3.5mm; the diameter of the zigzag opening roller is 64mm, and the number of opening teeth is 13 rows; the combination multiple is 105; the diameter of the rotor 3 is 40mm; mm; the winding angle is 32°, and the winding speed is 160m / min.

[0064] The quality of the 10 yarns produced in this embodiment reaches: the average breaking strength is 782.8cN, the breaking strength is 15.26cN / tex, and the evenness CVm% is 10.18.

Abstract

The invention relates to a revolving cup spinning twisting process. Drawn slivers are fed into a carding cavity through a feeding horn mouth 1 and a cotton feeding roller of an open-end spinning frame; dust produced when the drawn slivers are carded into monofilaments through a carding roller is discharged through an impurity discharging port, and the rotating speed of the carding roller is 8500-8800r / min; when a revolving cup works, the rotating speed of the revolving cup is 60000-64000r / min, and negative pressure of the process is 6.8-7.0kpa; yarns are twisted through a twist stopper and a twist setter, and the degree of twist of the yarns after the yarns are twisted is 430-450 twists / m; after being twisted, the yarns are drafted through a yarn guiding glass tube, a leather roller and a yarn guiding roller, wherein the draft multiple is 70-80 times; after being drafted, the yarns are wound on a paper tube through a winding roller to form a bobbin. By means of the revolving cup spinning twisting process, high count yarns can be spun, twist grains of the yarns are clear, the strength of the yarns is high, product quality is good, and improvement cost and production cost are low.

Description

technical field [0001] The invention relates to a rotor spinning technology, in particular to a rotor spinning twisting process. Background technique [0002] Rotor spinning belongs to the open-end spinning method. At present, the yarn produced by the rotor spinning machine accounts for about 40% of the total staple fiber yarn in the world. The raw material used in rotor spinning is fiber thick sliver, which is different from the roving used in ring spinning. It can be fed into the rotor spinning machine for rotor spinning without multiple careful drafting and carding. Spinning twisting and winding are carried out separately, the spinning speed is not affected by the yarn package, and the rotating speed of the rotor is extremely high, so the rotor spinning has the advantages of high spinning speed, large package and low cost, which is beneficial to The raw material requirements are low, but because the free ends of the rotor spinning are formed into yarns in an overlapping ...
