Kev kho cov xov paj ntau
Cov plaub hau pob → shearing tshuab → kiv cua → me me sib tov rau hauv → qee qhov ntev ntawm cov ntaub plaub (lwm cov fibers) → paj rwb ntaub qhib tshuab → ntxuam → loj sib tov rau hauv → sib tov raw khoom → ntim.
Kev hloov pauv ntawm cov txheej txheem carding feem ntau suav nrog: lub tog raj kheej, daim npav tiaj tus khaub ncaws, licker daim npav cov khaub ncaws thiab paj rwb pub board. Cov khaub ncaws daim npav yuav tsum tau hloov nrog daim npav tshwj xeeb lossis daim npav ob lub hom phiaj cov khaub ncaws tsim nyog rau spinning tshuaj fibers, thiab cov paj rwb board yuav tsum tau hloov nrog ib tug ob-curved ua hauj lwm nto haum rau spinning nruab nrab thiab ntev fibers. Cov xov paj ntau nws tus kheej yog spun yarn lossis filament yarn, tab sis nws muaj qhov ntim loj dua li cov xov paj qub, loj thiab mos. Nws suav nrog peb hom hauv qab no:
1) Cov xov paj ntau: Acrylic yarn fiber yog thermoplastic. Thaum nws yog cua sov, nws yuav tsim elongation ntau dua, thiab tom qab ntawd nws yuav txias thiab kho kom tsim tau lub siab shrinkage fiber ntau. Cov fiber ntau no yog sib xyaw nrog cov fiber ntau los ua cov xov paj spun. Tom qab steaming, lub siab shrinkage fiber ua longitudinal shrinkage thiab sib sau ua ke hauv cov tub ntxhais ntawm cov xov paj. Cov ntaub ntawv zoo tib yam cov ntaub ntawv crimps los yog loops thiab bulges ua rau cov xov paj ua Bulking, uas qhia ntau zog, qhov no yog bulked yarn.
2) Textured yarn yog cov xov paj uas tau raug textured. Nyob rau hauv cov txheej txheem ntau lawm, qee txoj kev siv los ua kom cov txhob lo lo ntxhuav fiber ntau tsim crimps mus tas li, loops thiab buckles, yog li qhov sib txawv ntawm cov fibers nce thiab cov xov paj lub cev yog loj. Yog li ntawd, cov xov paj textured muaj cov yam ntxwv tseem ceeb ntawm spun yarn - nws yog sov thiab breathable.
3) Stretch yarn Stretch yarn muaj qib siab ntawm elongation (3--5 zaug) thiab muaj peev xwm rov qab los. Thaum nws ncav cuag, nws zoo li ib txwm filament yarn; thaum nws yog tag nrho so, nws zoo li ib tug bulked yarn. Cov xov paj feem ntau yog ua los ntawm cov thermoplastic filaments (nylon). Cov filaments yog crimped mus tas li tom qab tsis tseeb twisting thiab kub teeb, tab sis tsis muaj entanglement ntawm cov filaments. Knitted ris tsho hauv qab ua nrog nws muaj kev xav zoo.
