Igama elithi nonwoven alisho “okulukiweyo” noma “okuhlanganisiwe”, kodwa indwangu ingaphezulu kakhulu. Okungalukiwe kuyisakhiwo sendwangu esikhiqizwa ngokuqondile ngemicu ngokubopha noma ukuhlangana noma kokubili. Ayinaso isakhiwo sejiyomethri esihlelekile, kunalokho iwumphumela wobudlelwane phakathi kwefayibha eyodwa nenye. Izimpande zangempela zama-nonwovens zingase zingacaci kodwa igama elithi "izindwangu ezingalukiwe" laqanjwa ngo-1942 futhi zakhiqizwa e-United States.
Izindwangu ezingezona ezilukiwe zenziwe ngezindlela ezi-2 eziyinhloko: zingazizwa noma ziboshwe. Indwangu engalukiwe ezwayo ikhiqizwa ngokwendlalela amashidi amancane, bese kusetshenziswa ukushisa, umswakama kanye nokucindezela ukuze inciphe futhi icindezele imicu ibe yindwangu ewugqinsi engeke ihlakazeke noma ihlakazeke. Futhi kunezindlela ezi-3 eziphambili zokwenza izindwangu ezingalukiwe eziboshiwe: I-Dry Laid, I-Wet Laid & Direct Spun. Enqubweni yokukhiqiza Indwangu Engalukiwe Eyomile Eyomile, iwebhu yemicu ibekwa esigubhini bese kufakwa umoya oshisayo ukuze kuhlanganiswe imicu ndawonye. Enqubweni yokukhiqiza Indwangu Engalukiwe Eyekiwe Emanzi, iwebhu yemicu ixutshwa nesixazululi esithambisayo esikhipha into efana neglue ehlanganisa imicu ndawonye bese iwebhu iyendlalwa ukuze yome. Enqubweni yokukhiqiza Indwangu Engalukiwe Eqondile Ye-Spun, imicu iphothwa ebhandeni lokuthutha futhi amaglue afuthwe emiculweni, bese icindezelwa ukuze ibhonde. (Uma kunemicu ye-thermoplastic, iglue ayidingeki.)
Imikhiqizo ye-Nonwoven
Nomaphi lapho uhlezi noma umi khona manje, vele ukhokhe ukubheka nxazonke futhi u-surly uzothola okungenani indwangu eyodwa engalukiwe. Izindwangu ezingalukiwe zingena ezimakethe eziningi ezihlanganisa ezokwelashwa, izingubo, ezezimoto, ukuhlunga, ukwakhiwa, ama-geotextiles kanye nokuvikela. Usuku nosuku ukusetshenziswa kwendwangu engalukiwe kuyanda futhi ngaphandle kwazo ukuphila kwethu kwamanje bekuyoba okungaqondakali. Ngokuyisisekelo kunezinhlobo ezi-2 zendwangu engalukiwe: Ehlala isikhathi eside futhi Iyalahlwa. Cishe u-60% wendwangu engalukiwe iqinile futhi ukuphumula okungu-40% kuyalahlwa.
Okumbalwa Okusha Embonini Engalukiwe:
Imboni engalukiwe ihlale ithuthukiswa ngezinto ezintsha ezidinga isikhathi futhi lokhu kusiza nasekuthuthukiseni amabhizinisi.
Ama-Surfaceskins (Nonwovens Innovation & Research Institute- NIRI): Amaphedi okuphusha iminyango elwa namagciwane kanye nezibambo zokudonsa eziklanyelwe ukubulala amagciwane afakiwe kanye namagciwane ngemizuzwana ebalulekile, phakathi komsebenzisi oyedwa nomunye odlula emnyango. Ngakho-ke kusiza ukuvimbela ukusabalala kwamagciwane namagciwane phakathi kwabasebenzisi.
I-Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Lobu buchwepheshe buletha ubuchwepheshe belayini obukhiqiza kakhulu, obuthembekile nobusebenza kahle obunciphisa izingcezu eziqinile ngamaphesenti angama-90; kwandisa okukhiphayo kuze kufike ku-1200 m/min; kunciphisa isikhathi sokugcina; kunciphisa ukusetshenziswa kwamandla.
I-Remodelling™ Compound Hernia Patch (i-Shanghai Pine & Power Biotech) : Kuyisiqephu se-electro-spun nano-scale esixhunyelelwa ngebhayoloji engabizi kakhulu futhi sisebenza njengendawo yokukhula yamangqamuzana amasha, ekugcineni awolise; ukunciphisa izinga lezinkinga zangemva kokuhlinzwa.
Isidingo Somhlaba Wonke:
Ukugcina cishe isikhathi esinganqamuki sokukhula eminyakeni engama-50 edlule, i-nonwoven ingaba ingxenye yokuphuma kwelanga yemboni yendwangu yomhlaba wonke enenzuzo ephezulu yenzuzo kunanoma yimiphi eminye imikhiqizo yendwangu. Imakethe yomhlaba wonke yendwangu engalukiwe iholwa yiChina enesabelo semakethe esicishe sibe ngama-35%, ilandelwe yi-Europe ngesabelo semakethe esingama-25%. Abadlali abahamba phambili kulo mkhakha i-AVINTIV, iFreudenberg, iDuPont ne-Ahlstrom, lapho i-AVINTIV ingumkhiqizi omkhulu kunayo yonke, enesabelo semakethe sokukhiqiza cishe esingu-7%.
Muva nje, ngokukhuphuka kwamacala e-COVIC-19, isidingo senhlanzeko nemikhiqizo yezokwelapha eyenziwe ngendwangu engalukiwe (njengalezi: amakepisi okuhlinzwa, imaski yokuhlinza, i-PPE, iphinifa lezokwelapha, izembozo zezicathulo njll) senyuke safinyelela ku-10x 30x emazweni ahlukene.
Ngokombiko wesitolo esikhulu kunazo zonke socwaningo lwemakethe emhlabeni "I-Research & Markets", imakethe ye-Global Nonwoven Fabrics yabalelwa ku- $ 44.37 billion ngo-2017 futhi kulindeleke ukuthi ifinyelele ku- $ 98.78 billion ngo-2026, ikhula ku-CAGR ka-9.3% ngesikhathi sokubikezela. Kuphinde kucatshangwe ukuthi imakethe eqinile engalukiwe izokhula ngenani eliphakeme le-CAGR.
Kungani Ingalukiwe?
Ama-Nonwovens ayasungula, ayadala, ayashintshashintsha, ubuchwepheshe obuphezulu, ayaguquguquka, abalulekile futhi ayabola. Lolu hlobo lwendwangu lukhiqizwa ngokuqondile emicu. Ngakho-ke asikho isidingo sezinyathelo zokulungiselela intambo. Inqubo yokukhiqiza ifushane futhi ilula. Lapho ukukhiqiza amamitha angu-5,00,000 endwangu elukiwe, kuthatha izinyanga eziyisi-6 (izinyanga ezi-2 ukulungisa intambo, izinyanga ezi-3 zokweluka kuma-looms angama-50, inyanga eyodwa ukuqeda nokuhlola), kuthatha izinyanga ezi-2 kuphela ukukhiqiza inani elifanayo indwangu engalukiwe. Ngakho-ke, lapho izinga lokukhiqizwa kwendwangu elukiweyo liyi-1 mete/minithi futhi izinga lokukhiqiza lendwangu ehlanganisiwe liyimitha engu-2/minute, kodwa izinga lokukhiqiza lendwangu engalukiwe liyi-100 imitha/ngomzuzu. Ngaphezu kwalokho izindleko zokukhiqiza ziphansi. Ngaphandle kwalokho, indwangu engalukiwe ebonisa izici ezithile ezifana namandla aphakeme, ukuphefumula, ukumunca, ukuqina, isisindo esilula, amalangabi abambezelekayo, ukulahlwa njll. Ngenxa yazo zonke lezi zici ezimangalisayo, imboni yendwangu ibheke ezindwangu ezingalukiwe.
Isiphetho:
Indwangu engalukiwe ngokuvamile kuthiwa iyikusasa lemboni yendwangu njengoba isidingo sabo somhlaba wonke kanye nokuguquguquka kwezinto kuya ngokuya kukhula futhi phezulu.
