1. Cov txheej txheem ntxuav thiab daim npav
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam cov ntaub yog siv cov combing rau kev tu thiab ua kom tiav cov khoom sib xyaw ua ke thiab cov paj rwb sib xyaw. Lub stripping ceev ntawm lub tshuab-carding unit yog 135 meters ib feeb, thiab qhov ntev ntawm txhua lub tog raj kheej yog 3800 meters.
2. Kev sib tw
Daim duab siv 6-8 daim ntawm cov xov paj sib xyaw. Cov paj rwb sliver tom qab ntawm lub tshuab muab faib ua ob ntu, nrog rau qhov siab ntawm 3800 meters ib chim thiab qis qis ntawm 1900 meters ib chim. Thaum thauj cov sliver, pub cov sliver los ntawm lub overhead mus rau hauv lub compression roller, nkag mus rau lub tswb lub qhov ncauj, thiab rub tawm lub taw tes taw tes kom paub tseeb tias tsis muaj pob qij txha nyob rau hauv lub sliver.
3. Scroll
24-36 daim yog siv ua ke, thiab ib daim ntawm paj rwb sliver yog siv. Xam ntau npaum li cas cov paj rwb yob tuaj yeem spun rau ib lub nruas ntawm paj rwb sliver. Tom qab spinning lub sliver, uniformly pub lub pre-drawn sliver los ntawm cov hloov sliver, thiab kos nws. Thaum nws yog uniformly spun rau ib lub tshuab combing rau lub cim, raws sij hawm pinch nws tawm.
4. Sib
Uniformly hloov lub yob thiab kho qhov ntev. Thaum lub spinning puv, lub sij hawm pinch tawm lub taw tes taw tes.
5. Rov
Lub tshuab rov qab faib cov paj rwb sliver nyob rau sab nraum qab ntawm lub thav duab rau hauv 6 seem, txhua 20 spindles muab faib ua ib seem, thiab txhua ob kab ntawm roving yog poob los hloov ib feem ntawm paj rwb sliver. Cov ntsiab lus hloov lub taub hau yog spun rau tag nrho cov xov paj, thiab lub taub hau cov ntsiab lus raug rub tawm los ntawm 2 meters. Thaum cov xov paj poob lawm, sab hauv kab ntawm cov xov paj loj poob mus rau ib qho chaw, thiab cov kab sab nrauv poob rau ib qho chaw. Thaum siv cov xov paj spinning, hloov cov xov paj raws li cov kab sab hauv thiab sab nrauv, thiab nruj me ntsis tswj lub roving elongation thiab qhov sib txawv.
6. Spun yarn
Cov txheej txheem spinning yog ua raws li txoj kev pav segmented, siv txoj kev hloov pauv hauv nruab nrab. Qhov kawg 15-20 laps ntawm txhua roving yog tshuav tsis siv. Sau cov xov paj loj, xov rau hauv lub tswb lub qhov ncauj, thiab tom qab ntawd tawg qhov sib koom ua ke ntawm lub raj xov paj. Tom qab rub tawm lub raj, siv txoj kev winding rau cov menyuam sib koom ua ke los tiv thaiv kev hloov lub pob ntawm roving. Qhov sib koom taw tes yog pinched tawm los ntawm txoj kev winding.
Txhua txoj kev siv txoj kev sib koom ua ke, thiab siv cov khoom ruaj khov. Kev tswj nruj ntawm tus nqi ntawm cov xov paj siv tau txhim kho kev tsim khoom thiab cov xov paj zoo. Cov ntaub zoo tau lees paub los ntawm cov neeg siv khoom, thiab qib zoo ntawm cov khoom tau raug txhim kho.
