Ukufezekisa iNkqubo yeSpunlace

Kwimveliso ye-hydroentangled nonwovens (i-spunlacing), intliziyo yenkqubo yi-injector. Eli candelo libalulekileyo linoxanduva lokuvelisa ii-water jets ezikhawulezayo ezibangela ukuxinana kwefayibha yokwenyani. Isiphumo seminyaka eliqela yokuphuculwa ngokusekelwe kwingxelo yabathengi kunye nokusebenza kwayo, i-neXjet Injector evela kwiUAndritz Perfojetimele iteknoloji yanamhlanje.

Ngaphambi kokufika kwe-hydroentanglement (i-spunlacing), ii-nonwoven webs zazibotshelelwa ngoomatshini ngeenaliti, zibotshelelwe ngamakhemikhali okanye zibotshelelwe ngobushushu ukuze zinike amandla kwi-fiber web. I-Spunlacing yaphuhliswa ukuze kuvumeleke abavelisi abangelukanga ukuba benze amalaphu anobunzima obulula (ngaphantsi kwe-100 gsm kunye neefayibha ezincinci ezingaphantsi kwe-3.3 dtex) besebenzisa "iinaliti zamanzi" ezinoxinzelelo oluphezulu ukubopha i-web yeefayibha ezikhululekileyo ukuze kubonelelwe ngokuthembeka kwelaphu. Ukuthamba, ukuguqa, ukuhambelana kunye namandla aphezulu zezona mpawu ziphambili ezidale imfuno yee-spunlace nonwovens.

Inkqubo yokufakelwa kwamanzi yaphuhliswa eMelika ngeminyaka yoo-1960. Ingcali kwelo candelo yayiyiDuPont, eyagqiba ekubeni ifumane amalungelo ayo omenzi wechiza kuluntu ngeminyaka yoo-1980. Ukususela ngelo xesha, le nkqubo iye yaphuhliswa ngakumbi ukuze isebenze kakuhle kwaye ifikeleleke lula ngababoneleli betekhnoloji abanjengoAndritz Perfojet.

I-Andritz iphumelele kakhulu kwimarike yase-Asia. Kwiinyanga ezimbalwa ezidlulileyo, imigca emininzi ye-Andritz spunlace ithengisiwe eTshayina. NgoJanuwari, inkampani igqibe isivumelwano noHangzhou Pengtu, umvelisi waseTshayina ongengowoluki, ukubonelela ngomgca omtsha oza kuqala ukusebenza—onobubanzi obusebenzayo obuziimitha ezi-3.6—kwikota yesithathu ka-2017. Ububanzi bokubonelela buquka ukuhanjiswa komgca we-Andritz neXline spunlace eXcelle onamakhadi amabini e-TT, ngoku ongumgangatho omtsha eTshayina wokuvelisa iiwipes ezinomthamo ophezulu.

Umgca omtsha we-nonwovens uza kuba nomthamo wonyaka weetoni ezingama-20,000 wokuvelisa amalaphu e-spunlace ukusuka kwi-30-80 gsm. Iyunithi ye-Jetlace Essentiel hydroentanglement kunye ne-neXdry through-air dryer nazo ziyinxalenye yeodolo.
