Embodiment 1
[0019] Raw material preparation: viscose fiber 1.33dtex×38mm,
[0020] (1) Spinning specification: 16.7tex
[0021] (2) Cleaning process
[0022] 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.
[0023] 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;
[0024] (2) Carding process
[0025] The FA231AB carding machine is selected, the rotation speed of the cyli...
Embodiment 2
[0034] Raw material preparation: cotton 229, micronaire value 4.3
[0035] Spinning specifications: 16.7tex
[0036] The spinning process of this embodiment is the same as that of Embodiment 1.
[0037] 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
[0039] Raw material preparation: polyester 1.33dtex×38mm; cotton 229, micronaire 4.3
[0040] Spinning specification: polyester / cotton: 70 / 30
[0041] 16.7tex
[0042] Process flow:
[0043]
[0044] (1) Opening and cleaning process:
[0045] 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%;
[0046] 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...
