Kumvetsetsa ndi Kupewa Mapiritsi mu Nsalu za Polyester

Nsalu za polyester zimagwiritsidwa ntchito kwambiri pamakampani opanga nsalu chifukwa cha kulimba, mphamvu, komanso kusinthasintha. Komabe, imodzi mwazovuta zomwe ogula ndi opanga amakumana nazo ndi mapiritsi. Pilling imatanthawuza kupanga timipira tating'ono ta ulusi pamwamba pa nsalu, zomwe zingasokoneze maonekedwe ndi maonekedwe a zovala. Kumvetsetsa zomwe zimayambitsa mapiritsi ndikufufuza njira zopewera ndizofunikira kwa ogula ndi opanga.

Kukhazikika kwa nsalu za polyester kumapiritsi kumalumikizidwa kwambiri ndi zomwe zidapangidwa ndi ulusi wa polyester. Ulusi wa polyester umakhala wogwirizana pang'ono pakati pa ulusi womwewo, womwe umawalola kuti atuluke pansalu mosavuta. Chikhalidwe ichi, chophatikizidwa ndi kulimba kwa ulusi wambiri komanso kuthekera kokulirapo, kumathandizira kupanga mapiritsi. Kuphatikiza apo, ulusi wa polyester uli ndi kukana kupindika kwabwino, kukana kwa torsion, komanso kukana kuvala, zomwe zikutanthauza kuti zimatha kupirira kupsinjika kwakukulu pakavala ndi kuchapa. Komabe, kusasunthika komweku kungapangitse kuti ulusiwo ukhale wosasunthika ndi kupanga timipira tating'ono, kapena mapiritsi, pamwamba pa nsalu.

Mipira yaing'ono iyi ikapangidwa, sichotsedwa mosavuta. Panthawi yovala ndi kuchapa nthawi zonse, ulusiwo umakhala ndi mikangano yakunja, yomwe imasonyeza ulusi wambiri pamwamba pa nsalu. Kuwonekera kumeneku kumabweretsa kudzikundikira kwa ulusi wotayirira, womwe ukhoza kukodwa ndi kupakana wina ndi mzake, zomwe zimapangitsa kupanga mapiritsi. Zinthu zosiyanasiyana zimathandizira kuti pakhale pilling, kuphatikiza mtundu wa ulusi womwe umagwiritsidwa ntchito pansalu, magawo opangira nsalu, njira zopaka utoto ndi kumaliza, komanso momwe nsaluyo imavalira.

Pofuna kuthana ndi vuto la mapiritsi mu nsalu za polyester, njira zingapo zingagwiritsidwe ntchito panthawi yopanga. Choyamba, posakaniza ulusi, opanga asankhe mitundu ya ulusi yomwe simakonda kupiritsa. Posankha ulusi woyenera pa nthawi ya ulusi ndi kupanga nsalu, mwayi wa mapiritsi ukhoza kuchepetsedwa kwambiri.

Kachiwiri, kugwiritsa ntchito mafuta odzola panthawi yopangira mankhwala komanso kupaka utoto kungathandize kuchepetsa mikangano pakati pa ulusi. M'makina opaka utoto wa jeti, kuwonjezera mafuta opangira mafuta kumatha kupanga kulumikizana bwino pakati pa ulusi, potero kumachepetsa mwayi wopaka pilling. Njira yowonongekayi ingapangitse nsalu yokhazikika komanso yokongola kwambiri.

Njira inanso yothandiza yopewera kupilira mu nsalu zophatikizika za poliyesitala ndi ma cellulose ndikuchepetsa pang'ono alkali pagawo la polyester. Njirayi imaphatikizapo kuchepetsa mphamvu ya ulusi wa polyester pang'ono, kuti zikhale zosavuta kuti timipira tating'ono tating'ono tomwe timapanga tichotsedwe pamwamba pa nsalu. Mwa kufooketsa ulusi wokwanira, opanga amatha kukulitsa magwiridwe antchito ndi mawonekedwe a nsalu.

Pomaliza, pamene mapiritsi ndi nkhani yodziwika bwino yokhudzana ndi nsalu za polyester, kumvetsetsa zomwe zimayambitsa ndikugwiritsa ntchito njira zopewera zomwe zingathe kuchepetsa vutoli. Posankha zosakaniza zoyenera za ulusi, kugwiritsa ntchito mafuta odzola panthawi yokonza, ndikugwiritsa ntchito njira zochepetsera pang'ono za alkali, opanga amatha kupanga nsalu zapamwamba za polyester zomwe zimasunga mawonekedwe komanso kulimba pakapita nthawi. Kwa ogula, kudziwa zinthu izi kungathandize kupanga zosankha mwanzeru pogula zovala za polyester, zomwe zimatsogolera ku chidziwitso chokhutiritsa ndi zovala zawo.
