Embodiment 1

[0018] Raw material preparation: viscose fiber 1.33dtex×38mm,

[0019] (1) Spinning specification: 16.7tex

[0020] (2) Cleaning process

[0021] Adoption process: FA002A type plucking machine → SFA035C type mixed cotton opener → FA025 type multi-compartment cotton blender → FA106A type porcupine opener → SFA161 type vibrating cotton feeder → A076F type lapping machine.

[0022] The cleaning process follows the principle of short process, low speed, less beating and less shedding, and minimizes fiber damage and kinks. The SFA035C cotton opener adopts the lowest speed, and the porcupine opener uses a comb beater with a beater speed of 480r / min, the lapping machine's comprehensive beater speed is 795r / min, the cotton lap quantitative design is 380g / m, and the cotton lap uniformity is 0.8%; in order to fully mix and evenly process, a multi-compartment blender is used;

[0023] (2) Carding process

[0024] The FA231AB carding machine is selected, the rotation speed of the cyli...

Embodiment 2

[0033] Raw material preparation: cotton 229, micronaire value 4.3

[0034] Spinning specifications: 16.7tex

[0035] The spinning process of this embodiment is the same as that of Embodiment 1.

[0036] Through various performance tests, compared with Comparative Example 2, the hairiness of the yarn provided by the present invention is reduced by 10%, the evenness CV is improved by 0.2, the yarn strength is increased by 10%, the kink is reduced by 28%, and the yarn has no torsional stress , the yarn has a strand effect that is soft and smooth.

Embodiment 3

[0038] Raw material preparation: polyester 1.33dtex×38mm; cotton 229, micronaire 4.3

[0039] Spinning specification: polyester / cotton: 70 / 30

[0040] 16.7tex

[0041] Process flow:

[0042]

[0043] (1) Opening and cleaning process:

[0044] Cotton: The beater speed of the plucking machine is 900r / min, and the beater extends out the ribs by 2mm; the distance between the corner nail curtain and the cotton pressing curtain of the SFA035C type mixed opening machine is 20mm, and the average cotton beater speed is ≤160 r / min. Parallel beater speed Ⅰ 300 r / min, II 360 r / min, nose beater speed 480 r / min, FA106A porcupine opener beater speed 480r / min, lap machine comprehensive beater speed 795r / min, lap weight unevenness 0.7%;

[0045] Polyester: The beater speed of the cotton catching machine is 900r / min, and the beater extends out the ribs by 2mm; the distance between the corner nail curtain and the cotton pressing curtain of the SFA035C type mixed opening machine is 20mm, an...

Abstract

The invention provides flexible smooth yarn and a production method thereof. The raw materials of the yarn is one or more of natural fibers or chemical fibers. The yarn is characterized in that compact siro spinning is combined with low-torsion spinning, two rough yarn parallel feeding is used during a spun yarn procedure, design twist coefficient of the yarn can be lowered at 280-300, fibers are tightly held together under action of a suction groove in a spinning trigonum, two completely drafted and gathered fiber bundles obtains more twisting before plying compared with common compact siro spinning due to the fact that false twist of low-torsion spinning is higher than intensive false twist of spun yarn formation twist, and more outstanding plying effect different from common compact siro spinning structures is achieved. The produced yarn is flexible and smooth, low in residual stress, and has plying effect, strength of the yarn is increased by 10-15%, hairness is lowered by 75-80%, evenness CV% is lowered by about 0.2%, and yarn twisting number is lowered by 20-30%.

Description

technical field [0001] The invention relates to a soft and smooth yarn and a production method thereof, belonging to the field of spinning engineering. Background technique [0002] Compact siro spinning is a combined spinning method combining compact spinning and siro spinning. Before the compact spun yarn is twisted, the fibers in the sliver are fully straightened, parallel to each other, and arranged closely. There is no traditional "addition". Twist triangle area", the yarn hairiness is less and the yarn strength is improved, but the yarn is uneven and the coarse details are not obviously mentioned; the two rovings are drafted at the same time in the siro spinning process to improve the evenness and reduce the coarse details. Less hairiness and higher strength; compared with traditional compact spinning and siro spinning, the compact siro spinning system is a combination of the two, and there is no fundamental change in the drafting device and twisting and winding device...
