Thiab blending ratio ntawm core spun yarn

3.1 Kev txiav txim siab ntawm tus naj npawb ntawm cov tub ntxhais spun yarns tus naj npawb ntawm cov core spun yarns tiav yuav tsum nyob ntawm lub hom phiaj ntawm cov khoom. Cov core spun yarn rau lub tsho thiab tiab feem ntau yog woven nrog ib lub xov paj, yog li cov xov paj suav yuav tsum tsawg, xws li 11.8 tex (50s) rau cov ris tsho hauv qab muaj zog thiab 18.45 tex (32S) rau cov thom khwm muaj zog; 36.9l-28.12rex (16-21s) rau weaving elastic corduroy thiab 73.82-49.21tex (8-12s) rau weaving elastic work card; 15.54-10.74tex (38-55s) yog siv rau cov ntaub rotten; Ib qho strand ntawm core spun yarn ntawm xaws xov yog cov xov sib txuas, yog li cov core spun yarn siv feem ntau nruab nrab thiab siab suav, xws li 13.12tex (45s), 11.14tex (53s), thiab lwm yam 3.2 kev txiav txim siab ntawm kev sib xyaw ua ke tom qab tus lej ntawm cov core spun yarn raug xaiv, qhov sib xyaw sib xyaw tuaj yeem suav tau raws li kev suav cov mis (cov mis laij lej raug rho tawm). Piv txwv li, rau zus tau tej cov 11.8 tex (50s) polyester paj rwb core spun yarn, qhov tseeb blending piv ntawm cov xov paj yog: Polyester account rau 49.36 feem pua ​​thiab paj rwb nyiaj rau 50.64 feem pua; Cov ntaub ntawv suav tau ze heev rau qhov kev tsim khoom tiag tiag. Txawm li cas los xij, thaum tsim qhov sib piv ntawm cov core spun yarn rau rotten fabric, qhov feem ntawm paj rwb yuav tsum loj dua. Ua ntej, hnav kev nplij siab ntawm cov ntaub thiab qhov thib ob, nws tuaj yeem ua rau peb qhov kev xav ntawm tus qauv tom qab rotten ntaub. Piv txwv li, 23.62tex (25s) paj rwb / polyester blending piv yog 66.67/33.33; 11.14tex (53s) paj rwb / polyester sib piv: 52.35/47.65, thiab lwm yam Spandex filament nyob rau hauv elastic core spun yarn feem ntau siv ib tug blending piv ntawm 15 feem pua ​​- 20 feem pua, uas tsis tau tsuas yog ua tau raws li cov kev cai ntawm elastic elongation ntawm weft siab elastic. ntaub ntawm 35 feem pua, tab sis kuj pab txhim kho lub zog ntawm core spun yarn. Kev txiav txim siab ntawm twist coefficient ntawm core spun yarn lub zog ntawm core spun yarn txo qis nrog qhov nce ntawm twist coefficient, vim hais tias lub zog ntawm filament txo nrog qhov nce ntawm twist coefficient. Thaum cov paj rwb cov ntsiab lus tsawg dua 50 feem pua, txawm hais tias lub zog ntawm cov ntaub qhwv staple fiber ntau nce nrog qhov nce ntawm twist coefficient thaum nws nyob rau hauv qhov tseem ceeb twist coefficient, tus qub plays lub luag hauj lwm tseem ceeb, yog li qhov twist coefficient ntawm core spun yarn yuav tsum yog. qis. Txawm li cas los xij, qhov sib tw sib tw ntawm polyester paj rwb core spun yarn siv rau cov ntaub rotten yuav tsum tsis txhob me me, uas feem ntau tswj tau ntawm 304-333, kom tsis txhob muaj qhov tsis xis nyob ntawm cov ntaub rotten. Lub twist coefficient ntawm spandex core spun yarn yog 20-30 siab tshaj lub nplhaib spun ntshiab paj rwb yarn ntawm tib yam ntau yam (warp los yog weft) thiab tib suav (tus naj npawb), kom lub zog ntawm cov xov paj ntawm ob yog nyob ze.
