Nsalu Yopanda Ulusi ya Spunlacechiyambi

Njira yakale kwambiri yolumikizira ulusi mu ukonde ndi yolumikiza makina, yomwe imakola ulusiwo kuti upatse ukonde mphamvu.

Pogwiritsa ntchito makina olumikizirana, njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri ndi kubowola ndi kuluka.

Spunlacing imagwiritsa ntchito madzi othamanga kwambiri kuti igwire ukonde kuti ulusi ugwirizane. Chifukwa chake, nsalu zopanda ulusi zopangidwa ndi njira iyi zimakhala ndi mawonekedwe akeake, monga chogwirira chofewa komanso chopindika.

Japan ndiye kampani yayikulu yopanga nsalu zopanda nsalu zopangidwa ndi hydroentangled padziko lonse lapansi. Nsalu zopangidwa ndi thonje lopangidwa ndi spunlaced zinali matani 3,700 ndipo kukula kwakukulu kwa kupanga kukuonekabe.

Kuyambira m'ma 1990, ukadaulowu wakhala wothandiza komanso wotsika mtengo kwa opanga ambiri. Nsalu zambiri zolumikizidwa ndi madzi zakhala zikugwiritsa ntchito maukonde ouma (okhala ndi makadi kapena opangidwa ndi mpweya ngati zinthu zoyambira).

Izi zasintha posachedwapa chifukwa cha kuchuluka kwa ma wet-laid precursor webs. Izi zili choncho chifukwa Dexter akugwiritsa ntchito ukadaulo wa Unicharm popanga nsalu zopindika pogwiritsa ntchito nsalu zopindika ngati zoyambira.

Pakadali pano, pali mawu osiyanasiyana osiyanasiyana otanthauza spunlace yoluka monga jet entangled, water entangled, ndi hydroentangled kapena hydraulically needled. Mawu akuti, spunlace, amagwiritsidwa ntchito kwambiri mumakampani osaluka.

Ndipotu, njira ya spunlace ingatanthauzidwe motere: njira ya spunlace ndi njira yopanga zinthu zopanda ulusi yomwe imagwiritsa ntchito madzi kuti igwire ulusi motero imapangitsa nsalu kukhala yolimba. Kufewa, mawonekedwe ake, kusinthasintha, komanso mphamvu zake ndizo makhalidwe akuluakulu omwe amachititsa kuti spunlace yopanda ulusi ikhale yapadera pakati pa zinthu zopanda ulusi.

Nsalu Yopanda Ulusi Yopangidwa ndi Spunlace

Ulusi womwe umagwiritsidwa ntchito popanga nsalu zopanda nsalu ziyenera kuganizira za makhalidwe a ulusi.

Modulus:Ulusi wokhala ndi ma modulus otsika umafunikira mphamvu zochepa zokoka kuposa womwe uli ndi ma modulus okwera.

Kusalala:Pa mtundu wina wa polima, ulusi waukulu wa mainchesi ndi wovuta kuugwira kuposa ulusi wa mainchesi ang'onoang'ono chifukwa cha kupindika kwawo kwakukulu.

Kwa PET, anthu okana 1.25 mpaka 1.5 akuoneka kuti ndi abwino kwambiri.

Gawo lochepa lazambiri:Pa mtundu wina wa polima ndi chokana ulusi, ulusi wooneka ngati katatu udzakhala ndi kuuma kopindika kowirikiza ka 1.4 kuposa ulusi wozungulira.

Ulusi wopyapyala kwambiri, wozungulira kapena wooneka ngati elliptical ukhoza kukhala ndi kuuma kopindika kowirikiza ka 0.1 kokha kuposa ulusi wozungulira.

Utali:Ulusi waufupi umatha kuyenda bwino ndipo umapanga malo oti ugwire bwino kuposa ulusi wautali. Komabe, mphamvu ya nsalu imagwirizana ndi kutalika kwa ulusi;

Chifukwa chake, kutalika kwa ulusi kuyenera kusankhidwa kuti pakhale kusiyana pakati pa kuchuluka kwa malo olumikizirana ndi mphamvu ya nsalu. Pa PET, kutalika kwa ulusi kuyambira 1.8 mpaka 2.4 kumawoneka ngati kwabwino kwambiri.

Chiphuphu:Crimp imafunika mu makina opangira ulusi wamba ndipo imathandiziraKuchuluka kwa nsalu. Kukwinyika kwambiri kungayambitse kuchepa kwa mphamvu ya nsalu ndi kutsekeka.

Kunyowa kwa ulusi:Ulusi wokonda madzi umalowa mosavuta kuposa ulusi wokonda madzi chifukwa cha mphamvu zake zokoka.
