Txawm hais tias koj knitting koj thawj lub tsho, los yog knitting rau ib tug phooj ywg, koj yuav xav paub dab tsi yuav tsum xyuam xim rau thaum siv kub yaj xov paj. Kub yaj yarn yog ib hom nplaum uas khi fibers ua ke. Nws tuaj yeem hloov ntau yam ntawm cov nplaum sib txawv, suav nrog cov tshuaj nplaum, vim nws tsis muaj tshuaj lom. Thiab vim hais tias nws muaj qhov qis melting point, nws tuaj yeem zam plua plav paug thiab volatiles.
Muaj plaub hom kev knitting fibers. Cov no yog cov nroj tsuag fibers, tsiaj fibers, hluavtaws fibers, thiab biosynthetic fibers. Cog fibers muaj xws li paj rwb thiab linen. Tsiaj fibers muaj xws li ntaub plaub, thiab biosynthetic fibers muaj xws li rayon. Synthetic fibers muaj xws li nylon thiab acrylic.
Thaum siv cov xov paj kub yaj, xyuas kom nws tsis txhob raug kub siab tshaj nws qhov melting point. Nws tseem yog ib qho tseem ceeb uas yuav tau siv lub voj voog ntxhua khaub ncaws kom ntxuav cov hluavtaws fibers. Yog tias koj tab tom steaming cov khaub ncaws zaum kawg, siv qhov chaw qis tshaj plaws. Thiab tsis txhob raug tshav ntuj lossis los nag.
Nylon thermal fuse yog ib qho tshwj xeeb nylon yarn uas muaj kev tiv thaiv zoo, kev sib txuas thiab pasting zog, thiab yog ib puag ncig zoo. Nylon thermal fuse kuj muaj kev nyab xeeb, thiab nws tsis muaj ntxhiab.
Ntxiv nrog rau nws txoj kev sib txuas thiab kev ua kom muaj peev xwm, nylon thermal fuse kuj muaj qhov taw tes qis. Nws yog feem ntau siv los ua ntau hom fibers, nrog rau cov xov paj kub yaj. Nws tau raug siv los tsim cov xov paj los ntawm kev siv lub raj mis PET. Cov txheej txheem no suav nrog kev tu thiab txheeb xyuas cov fwj. Tom qab ntawd cov fwj tau ntim rau hauv cov pob loj thiab coj mus rau qhov chaw rov ua dua tshiab.
