Njengelungu leqembu le-Dörken, i-Multitexx idonsa cishe iminyaka engamashumi amabili yesipiliyoni ekukhiqizeni i-spunbond.
Ukuze kuhlangatshezwane nesidingo sama-nonwovens angasindi, anamandla aphezulu, i-Multitexx, inkampani entsha ezinze e-Herdecke, eJalimane, inikeza ama-nonwovens angama-spunbond enziwe nge-polyester yekhwalithi ephezulu (i-PET) ne-polypropylene (PP) ukuze asetshenziswe ngokufunwa.
Njengelungu leqembu lamazwe ngamazwe le-Dörken, i-Multitexx idonsa cishe iminyaka engamashumi amabili yesipiliyoni ekukhiqizeni i-spunbond. Inkampani engumzali yasungulwa eminyakeni eyi-125 edlule futhi yaqala ukuthuthukisa nokukhiqiza ama-underlays ophahleni olumisiwe ngeminyaka yawo-1960. Ngo-2001, u-Dörken wathola ulayini wokukhiqiza we-Reicofil spunbond futhi waqala ukukhiqiza ezawo izinto ze-spunbond zemakethe ehlanganisiwe yokwakha laminate.
"Ngemva kweminyaka engu-15, ukukhula okusheshayo kwebhizinisi kwaholela esidingweni sokuthenga umugqa wesibili we-Reicofil ophezulu," kuchaza inkampani. "Lokhu kuxazulule inkinga yamanani e-Dörken futhi kwanikeza nomfutho wokwakhiwa kwe-Multitexx." Kusukela ngoJanuwari 2015, inkampani entsha ibithengisa izinto zekhwalithi ephezulu ze-spunbond ezenziwe nge-thermal calendered polyester noma i-polypropylene.
Imigqa emibili ye-Dörken Group ye-Reicofil ingashintshanisa ukusetshenziswa kwama-polymer amabili futhi ikhiqize i-spunbond kusuka kunoma iyiphi into enokuminyana okuphansi nokuvumelana okuphezulu kakhulu. I-polymer ingena emugqeni wokukhiqiza ngokusebenzisa imigqa yokuphakelayo ehlukene elungiselwe okokuluhlaza okufanele. Njengoba izinhlayiya ze-polyester zihlangana ku-80°C, kufanele ziqale zicwebezeliswe futhi zomiswe ngaphambi kokukhishwa. Khona-ke ifakwa ekamelweni lokudosa, eliphakela i-extruder. Amazinga okushisa e-extrusion kanye nokuncibilika kwe-polyester aphezulu kakhulu kunalawo e-polypropylene. I-polymer encibilikisiwe (i-PET noma i-PP) bese iphonswa empompini yokuphotha.
Ukuncibilika kufakwa ku-die bese kusakazwa ngokushelelayo kubo bonke ububanzi bomugqa wokukhiqiza kusetshenziswa i-piece-piece die. Ngenxa yomklamo wayo wocezu olulodwa (oklanyelwe umugqa wokukhiqiza osebenza ububanzi obungamamitha angu-3.2), isikhunta sivimbela ukukhubazeka okungase kwakheke ezintweni ezingezona ezilukiwe ngenxa yokushisela okudalwe ukubunjwa kwezingxenye eziningi. Ngakho-ke, ama-spinnerets ochungechunge lwe-Reicofil akhiqiza imicu ye-monofilament ene-filament eyodwa ye-filament cishe ye-2.5 dtex. Bese zinwetshwa zibe imicu engapheli ngokusebenzisa ama-diffuser amade agcwele umoya emazingeni okushisa alawulwayo kanye nesivinini somoya.
Isici esihlukile sale mikhiqizo ye-spunbond ukuphrinta okumise okweqanda okudalwe ama-hot-calender embossing rollers. I-embossing eyindilinga yakhelwe ukukhulisa amandla aqinile wemikhiqizo engalukiwe. Kamuva, indwangu engalukiwe yekhwalithi ephezulu ye-spunbond idlula ezigabeni ezinjengolayini wokupholisa, ukuhlolwa kokukhubazeka, ukusika, ukusika nokujikajika, futhi ekugcineni ifinyelele ekuthunyelweni.
I-Multitexx inikezela ngezinto ze-polyester spunbond ezinokucoleka kwe-filament cishe ku-2.5 dtex kanye nokuminyana kusuka ku-15 kuya ku-150 g/m². Ngaphezu kokufana okuphezulu, izimfanelo zomkhiqizo kuthiwa zihlanganisa amandla aphezulu okudonsa, ukumelana nokushisa kanye nokuncipha okuphansi kakhulu. Ngezinto ze-spunbond polypropylene, okungezona okulukiwe okwenziwe ngezintambo ze-polypropylene okumsulwa nokuminyana okusuka ku-17 kuye ku-100 g/m² kuyatholakala.
Umthengi oyinhloko wezindwangu ze-Multitexx spunbond imboni yezimoto. Embonini yezimoto, kusetshenziswa inani lezinhlobonhlobo ze-spunbond, ngokwesibonelo, njenge-insulation yomsindo, ukufakwa kukagesi noma izinto zokuhlunga. Le nkampani ithi izinga labo eliphezulu lokufana lizenza zikufanelekele kahle ukuhlungwa koketshezi, olusetshenziswa ngempumelelo ezinhlobonhlobo zezinhlelo zokusebenza ukusuka ekusikeni ukuhluza uketshezi kuya ekuhlungeni kukabhiya.
Yomibili imigqa ye-spunbond isebenza ubusuku nemini futhi inokukhiqiza okuphezulu okufanayo. Ngokusho kwenkampani, iluphu ye-GKD CONDUCTIVE 7701 ingamamitha angu-3.8 ububanzi futhi icishe ibe ngamamitha angu-33 ubude, ihlangabezana nezindinganiso eziningi futhi ifanele ingcindezi yesikhathi eside. Idizayini yesakhiwo se-tape ikhuthaza ukuphefumula okuhle nokufana kwe-mesh. Kuthiwa futhi ukukhululeka kokuhlanza amabhande e-GKD kuqinisekisa ukusebenza okuphezulu.
"Ngokuphathelene nezakhiwo zomkhiqizo, amabhande e-GKD ngokungangabazeki angamabhande angcono kakhulu emgqeni wethu," kusho u-Andreas Falkowski, uMholi Wethimba le-Spunbond Line 1. Ngale njongo, siye sayala elinye ibhande ku-GKD futhi manje sililungiselela ukukhiqizwa. Kulokhu kuzoba yibhande elisha le-CONDUCTIVE 7690, elihlanganisa isakhiwo sebhande elimahhadla ngokuphawulekayo lapho uhamba khona.
Lo mklamo kuthiwa unikeza ibhande lokuthutha ukubamba okukhethekile okuklanyelwe ukuthuthukisa ukudonsa endaweni yokunqwabelanisa futhi kuthuthukise ukusebenza kahle kokuhlanza kwebhande lokuthutha. “Asikaze sibe nenkinga uma siqala ngemuva kokushintsha amabhande, kodwa indawo eqinile kufanele yenze kube lula ukukhipha ama-drip emabhandeni,” kusho u-Andreas Falkowski.
