Dab tsi yog bulked yarn?
Cov xov paj ntau yog thawj zaug sib xyaw rau hauv cov xov paj los ntawm ob fibers nrog sib txawv shrinkage tus nqi, thiab tom qab ntawd cov xov paj muab tso rau hauv chav lossis cua kub lossis dej kub rau kev kho mob. Thaum lub sij hawm no, cov fibers uas shrinks feem ntau shrink ho thiab yog nyob rau hauv nruab nrab ntawm cov xov paj. Nyob rau hauv qhov chaw, cov sib xyaw uas tsis tshua muaj shrinkage fibers yog nyem rau ntawm qhov chaw ntawm cov xov paj los tsim ib lub voj vim lawv me me shrinkage, yog li tau txais ib lub fluffy, plump, thiab elastic bulked yarn.
Wool pob → shearing tshuab → kiv cua → me me sib tov rau hauv → wool fibers (lwm fibers) ntawm ib tug ntev ntev → paj rwb ntaub qhib mixing tshuab → ntxuam → loj sib tov rau hauv → tov raw khoom → ntim.
Kev hloov pauv ntawm cov txheej txheem carding feem ntau suav nrog: lub tog raj kheej, daim npav tiaj tus, cov khaub ncaws licker-hauv daim npav thiab paj rwb pub phaj. Cov khaub ncaws daim npav yuav tsum tau hloov nrog daim npav tshwj xeeb lossis daim npav ob lub hom phiaj cov khaub ncaws haum rau spinning tshuaj fibers, thiab cov paj rwb pub phaj yuav tsum tau hloov nrog ob-kho qhov chaw ua hauj lwm nto haum rau spinning nruab nrab-ntev fibers. Cov xov paj bulked nws tus kheej yog cov xov paj luv luv lossis cov xov paj filament, tab sis nws muaj lub ntim loj dua li cov xov paj qub, thiab yog qhov loj thiab mos.
1) Cov xov paj ntau: Acrylic yarn fiber yog thermoplastic. Thaum stretched nyob rau hauv cua sov, nws yuav tsim elongation ntau dua, thiab ces txias thiab tsau rau hauv siab shrinkage fiber. Cov fiber ntau no yog sib xyaw nrog cov fibers zoo tib yam los ua cov xov paj luv luv. Tom qab steaming ua, lub siab shrinkage fibers shrinkage longitudinally thiab sib sau ua ke nyob rau hauv cov xov paj cores, thaum lub zoo tib yam fibers tsim curls los yog loops thiab bulge, ua rau cov xov paj qauv ua Bulking qhia ib tug nce nyob rau hauv ntim, uas yog bulked yarn.
2) Textured yarn yog hais txog cov xov paj filament uas tau dhau los ua texturing. Thaum lub sij hawm tsim cov txheej txheem, qee txoj kev siv los ua kom cov curls mus tas li, loops thiab wrinkles nyob rau hauv cov ntaub lo lo ntxhuav, yog li ua rau qhov sib txawv ntawm cov fibers thiab bulking lub cev xov paj.
3) Elastic yarn Elastic yarn muaj qib siab ntawm elongation (3-5 zaug) thiab muaj peev xwm rov qab los. Thaum nws ncav cuag, nws ua zoo li cov xov paj zoo tib yam; thaum nws yog tag nrho so, nws ua zoo li ib tug bulked yarn.
Cov xov paj yog dab tsi?
Khoom acrylic yarn yog tsim los ntawm polyacrylonitrile. Nws yog copolymerized nrog ntau tshaj 85% acrylonitrile thiab tsis pub ntau tshaj 15% thawj thiab thib peb monomers. Nws yog tsim los rau hauv luv fiber ntau los yog fiber ntau los ntawm ntub los yog qhuav spinning. Filament. Cov ntsiab lus acrylonitrile suav nrog ntau dua 85%, uas yog hu ua polyacrylonitrile. Ntshiab polyacrylonitrile muaj cov qauv nruj, nkig thiab tawv, thiab tsis zoo dyeability. *** monomers feem ntau siv cov tebchaw uas muaj ester pawg, xws li methyl acrylate, methyl methacrylate, vinyl acetate, thiab lwm yam. Tom qab cov *** monomer ntxiv, qhov tsis tu ncua ntawm cov txheej txheem ntawm macromolecules yuav zuj zus, thiab lub zog intermolecular tsis muaj zog, lub fibers ua looser nyob rau hauv microstructure, softness ntawm cov fiber yog nce, elasticity thiab xav tau zoo dua, thiab nws yog conducive rau kev taw qhia ntawm dye molecules thiab txhim kho cov dyeability ntawm fiber.
Nws muaj elasticity zoo, qhov thib ob tsuas yog polyester, txog 2 npaug siab dua li nylon, thiab muaj cov duab zoo dua qub. Lub teeb tsis kam ntawm acrylic fiber yog qhov zoo tshaj plaws ntawm tag nrho cov hluavtaws fibers, thiab nws lub zog tsuas yog txo los ntawm 20% tom qab raug tshav ntuj rau ib xyoos. Vim tias cov xov paj acrylic muaj qhov zoo fluffiness thiab muag muag, nws feem ntau siv los ua ntaub plaub, ntaub pua plag, thiab lwm yam.; vim tias nws muaj huab cua zoo tiv thaiv, mildew-pov thawj, thiab npauj-pov thawj cov khoom, nws tseem tuaj yeem muab spun purely los yog blended nrog ntuj fibers, thiab yog dav siv nyob rau hauv ntau yam kev siv. Tarpaulin, kho kom zoo nkauj, chaw ua haujlwm, ntaub thaiv npog thiab lwm yam lag luam; vim nws cov khoom ua kom sov sov zoo, nws kuj yog siv los ua khaub ncaws, plush, dag fur, thiab lwm yam.
Dab tsi yog qhov txawv ntawm cov xov paj thiab cov xov paj bulked?
1. Tom qab dyeing los yog cua sov, bulked yarn yuav tshwm jagged, thiab nto ntawm cov xov paj yuav qhia ib tug bulking nyhuv. Cov yarn khoom yuav tsis deform tom qab rhuab los yog dyed.
2. Cov xov paj bulked muaj shrinkable acrylic, uas shrinks thaum ntsib tshav kub thiab noo noo thaum lub sij hawm dyeing los yog bulking txheej txheem, ua rau cov xov paj nto qhia ib tug bulking nyhuv. Nws feem ntau yog siv rau hauv cov ntaub plaub los yog ntaub plaub knitted sweaters. Cov xov paj tsis muaj cov khoom shrinkage thiab feem ntau yog siv hauv cov ntaub woven.
3. Cov paj rwb khoom yuav tsis ntsws (xws li tsis luv) nyob rau hauv qhov kub thiab txias, thaum nthuav paj rwb yuav luv luv nyob rau hauv kub. Tus nqi shrinkage nyob ntawm tus yam ntxwv ntawm fiber ntau nws tus kheej. Cias muab: bulked xov paj yuav tshwm jagged tom qab dyeing los yog cua sov, thiab nto ntawm cov xov paj yuav qhia ib tug bulking nyhuv. Cov yarn khoom yuav tsis deform tom qab rhuab los yog dyed.
