Njengelungu leqela le-Dörken, i-Multitexx izoba malunga neminyaka engamashumi amabini yamava kwimveliso ye-spunbond.
Ukuhlangabezana nemfuno ye-lightweight, i-spunbond nonwovens ephezulu, i-Multitexx, inkampani entsha ese-Herdecke, eJamani, inikezela nge-spunbond nonwovens eyenziwe kwi-polyester ephezulu (PET) kunye ne-polypropylene (PP) yokufuna izicelo.
Njengelungu leqela lamazwe ngamazwe leDörken, iMultitexx izoba malunga neminyaka engamashumi amabini yamava kwimveliso yespunbond. Inkampani engumzali yasekwa kwiminyaka eyi-125 eyadlulayo kwaye yaqala ukuphuhlisa nokuvelisa uphahla oluphantsi kophahla kwiminyaka yoo-1960. Ngo-2001, uDörken wafumana umgca wemveliso weReicofil spunbond kwaye waqala ukuvelisa eyakhe imathiriyeli ye-spunbond kwimarike yolwakhiwo oluhlanganisiweyo lwelaminate.
"Emva kweminyaka eyi-15, ukukhula ngokukhawuleza kweshishini kwakhokelela kwisidingo sokuthenga umgca weReicofil wesibini ophezulu," kuchaza inkampani. "Oku kuyisombulule ingxaki yesikhundla eDörken kwaye kwanika umdla wokuyilwa kweMultitexx." Ukususela ngoJanuwari 2015, inkampani entsha ithengisa izinto eziphezulu ze-spunbond ezenziwe nge-thermal calendered polyester okanye i-polypropylene.
Imigca emibini yeReicofil yeQela leDörken inokutshintshana ukusetyenziswa kweepholima ezimbini kwaye ivelise i-spunbond kuyo nayiphi na imathiriyeli enoxinano oluphantsi kunye nokungaguquguquki okuphezulu kakhulu. I-polymer ingena kumgca wemveliso ngokusebenzisa imigca yokutya eyahlukileyo eguqulelwe kwizinto ezifanelekileyo ezikrwada. Ekubeni amasuntswana e-polyester agglomerate kwi-80 ° C, kufuneka aqale acwecwe kwaye omiswe ngaphambi kokuba akhutshwe. Emva koko ifakwe kwigumbi lokudoba, elondla i-extruder. I-extrusion kunye namaqondo okushisa okunyibilika kwe-polyester aphezulu kakhulu kunalawo e-polypropylene. I-polymer etyhidiweyo (i-PET okanye i-PP) ifakwe kwimpompo yokujikeleza.
Inyibilika ifakwe kwi-die kwaye isasazwe ngokufanelekileyo phezu kobubanzi bonke bomgca wemveliso usebenzisa i-piece-piece die. Ngombulelo kuyilo lwayo-nye (eyenzelwe umgca wemveliso osebenzayo ububanzi beemitha ezi-3.2), isikhunta sinqanda iziphene ezinokubakho kwizinto ezingabonakaliyo ngenxa ye-welds eyenziwe ngama-multi-piece molds. Ngaloo ndlela, i-spinnerets ye-Reicofil series ivelisa i-monofilament filaments kunye ne-filament filament fineness emalunga ne-2.5 dtex. Zithi ke zolule zibe yimisonto engapheliyo ngokusebenzisa iidiphaser ezinde ezizaliswe ngumoya kumaqondo obushushu alawulwayo kunye nezantya zomoya ophezulu.
Isici esahlukileyo kwezi mveliso ze-spunbond yi-oval-shaped imprint eyenziwe yi-hot-calender embossing rollers. I-embossing yesetyhula yenzelwe ukunyusa amandla okuqina kweemveliso ezingalukwanga. Emva koko, ilaphu elikumgangatho ophezulu we-spunbond nonwoven lidlula kwizigaba ezinje ngelayini yokupholisa, ukuhlolwa kwesiphene, ukusika, ukunqumla kunye nokujikajika, kwaye ekugqibeleni ifikelele ekuthunyelweni.
I-Multitexx ibonelela ngemathiriyeli ye-polyester spunbond enokulunga kwefilament malunga ne-2.5 dtex kunye noxinano ukusuka kwi-15 ukuya kwi-150 g/m². Ukongeza kokufana okuphezulu, iimpawu zemveliso kuthiwa ziquka ukomelela okuphezulu, ukumelana nobushushu kunye nokushwabana okuphantsi kakhulu. Kwimathiriyeli ye-spunbond ye-polypropylene, ii-nonwovens ezenziwe ngemisonto ye-polypropylene esulungekileyo enoxinano ukusuka kwi-17 ukuya kwi-100 g/m² ziyafumaneka.
Umthengi oyintloko wempahla ye-spunbond ye-Multitexx yimboni yeemoto. Kwishishini leemoto, inani leenguqu ze-spunbond lisetyenziswa, umzekelo, njenge-insulation yesandi, ukugqunywa kombane okanye izinto zokucoca. Inkampani ithi inqanaba labo eliphezulu lokufana likwabenza bakufanelekele ukuhluzwa kolwelo, olusetyenziswe ngempumelelo kuluhlu lwezicelo ukusuka ekusikeni ukuhluza ulwelo ukuya kuhluzo lwebhiya.
Zombini iilayini ze-spunbond zisebenza ubusuku nemini kwaye zinemveliso ephezulu ngokuhambelanayo. Ngokutsho kwenkampani, i-GKD's CONDUCTIVE 7701 loop yi-3.8 yeemitha ububanzi kwaye iphantse ibe yi-33 yeemitha ubude, ihlangabezana nemigangatho emininzi kwaye ifanele uxinzelelo lwexesha elide. Uyilo lwesakhiwo se-tape sikhuthaza ukuphefumla okulungileyo kunye nokufana kwe-mesh. Kwakhona kuthiwa ukukhululeka kokucoca amabhanti e-GKD kuqinisekisa ukusebenza okuphezulu.
"Ngokuphathelele kwiipropati zeemveliso, amabhande e-GKD ngokungangabazeki amabhande angcono kakhulu kumgca wethu," kusho u-Andreas Falkowski, iNkokeli yeQela le-Spunbond Line 1. Ngenxa yale njongo, siyalele elinye ibhanti kwi-GKD kwaye ngoku siyilungiselela ukuveliswa. Ngeli xesha iya kuba yibhanti entsha ye-CONDUCTIVE 7690, ebonisa isakhiwo sebhanti enqabileyo kakhulu kwindlela yokuhamba.
Olu luyilo kuthiwa lubonelela ngebhanti yokuhambisa ngentambo ekhethekileyo eyenzelwe ukuphucula i-traction kwindawo yokupakisha kunye nokwandisa ngakumbi ukucoceka kwebhanti yokuhambisa. “Asizange sibe nangxaki ukuqala emva kokutshintsha amabhanti, kodwa umphezulu orhabaxa kufuneka wenze kube lula ukususa iidriphu emabhantini,” utsho uAndreas Falkowski.
