Igama elithi nonwoven alisho ukuthi “lukiwe” noma “luthungiwe”, kodwa indwangu ingaphezu kwalokho. I-Nonwoven isakhiwo sendwangu esikhiqizwa ngqo ngemicu ngokubopha noma ukuxhumanisa noma kokubili. Ayinaso isakhiwo esihlelekile sejometri, kunalokho ingumphumela wobudlelwano phakathi kwefibre eyodwa nenye. Izimpande zangempela ze-nonwoven zingase zingacaci kodwa igama elithi “izindwangu ezingezona ezilukiwe” laqanjwa ngo-1942 futhi lakhiqizwa e-United States.
Izindwangu ezingalukiwe zenziwa ngezindlela ezimbili eziyinhloko: ziyaqedwa noma ziyahlanganiswa. Indwangu engalukiwe eqediwe ikhiqizwa ngokubeka amashidi amancane, bese kufakwa ukushisa, umswakama kanye nengcindezi ukuze kuncishiswe futhi kucindezelwe imicu ibe yindwangu ebanzi ehlanganisiwe engeke igqagqe noma iqhekeke. Kukhona futhi izindlela ezintathu eziyinhloko zokukhiqiza izindwangu ezingalukiwe ezihlanganisiwe: I-Dry Laid, i-Wet Laid kanye ne-Direct Spun. Enqubweni yokukhiqiza i-Dry Laid Non-woven Fabric, i-web yemicu ibekwa esigubheni bese kufakwa umoya oshisayo ukuze kuhlanganiswe imicu ndawonye. Enqubweni yokukhiqiza i-Wet-Laid Non-woven Fabric, i-web yemicu ixutshwa nesithambisi esithambile esikhipha into efana neglue ebopha imicu ndawonye bese i-web ibekwa ukuze yome. Enqubweni yokukhiqiza i-Direct Spun Non-woven Fabric, imicu iphothwa ebhandeni lokuhambisa bese kufakwe ama-glue ku-fiber, bese ecindezelwa ukuze ahlangane. (Uma kwenzeka imicu ye-thermoplastic, i-glue ayidingeki.)
Imikhiqizo Engalukiwe
Noma ngabe uhleli noma umi kuphi njengamanje, bheka nje futhi ngokuzumayo uzothola okungenani indwangu eyodwa engalukiwe. Izindwangu ezingalukiwe zingena emakethe ahlukahlukene okuhlanganisa ezokwelapha, izingubo, izimoto, ukuhlunga, ukwakhiwa, ama-geotextile kanye nokuvikela. Usuku nosuku ukusetshenziswa kwendwangu engalukiwe kuyanda futhi ngaphandle kwazo impilo yethu yamanje ibiyoba yinto engaqondakali. Empeleni kunezinhlobo ezimbili zendwangu engalukiwe: Ehlala isikhathi eside kanye Nokulahlwa. Cishe u-60% wendwangu engalukiwe ihlala isikhathi eside kanti okunye okungu-40% kuyalahlwa.
Izinto Ezintsha Ezimbalwa Embonini Engalukiwe:
Imboni Engalukwanga ihlala icebiswa ngezinto ezintsha ezidinga isikhathi futhi lokhu kusiza nasekuthuthukiseni amabhizinisi.
Izikhumba ze-Surfaces (i-Nonwovens Innovation & Research Institute- NIRI): Ziyi-banding pushing door pads kanye nezibambo zokudonsa eziklanyelwe ukubulala amagciwane nama-bacteria agciniwe ngemizuzwana embalwa, phakathi komsebenzisi oyedwa nomunye odlula emnyango. Ngakho-ke kusiza ukuvimbela ukusabalala kwamagciwane nama-bacteria phakathi kwabasebenzisi.
I-Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Lobu buchwepheshe buhlinzeka ngobuchwepheshe bomugqa obukhiqiza kakhulu, obuthembekile futhi obusebenza kahle obunciphisa izingcezu eziqinile ngamaphesenti angama-90; kwandisa umkhiqizo ofinyelela ku-1200 m/min; kwenza kube lula isikhathi sokulungisa; kunciphisa ukusetshenziswa kwamandla.
I-Remodelling™ Compound Hernia Patch (i-Shanghai Pine & Power Biotech): Iyi-electro-spun nano-scale patch ekwazi ukumuncwa kalula futhi isebenza njengendawo yokukhula kwamaseli amasha, ekugcineni ibola; kunciphisa izinga lezinkinga zangemva kokuhlinzwa.
Isidingo Somhlaba Wonke:
Njengoba igcina isikhathi sokukhula esingapheli eminyakeni engama-50 edlule, i-nonwoven ingaba yingxenye ephuma phambili embonini yezindwangu yomhlaba wonke enenzuzo ephezulu kunanoma yimiphi eminye imikhiqizo yezindwangu. Imakethe yomhlaba wonke yezindwangu ezingalukiwe iholwa yiShayina enesabelo semakethe esingaba ngu-35%, ilandelwe yiYurophu enesabelo semakethe esingaba ngu-25%. Abadlali abaphambili kulo mkhakha yi-AVINTIV, iFreudenberg, iDuPont kanye ne-Ahlstrom, lapho i-AVINTIV ingumkhiqizi omkhulu kunabo bonke, enesabelo semakethe sokukhiqiza esingaba ngu-7%.
Muva nje, ngokwanda kwamacala e-COVIC-19, isidingo semikhiqizo yokuhlanzeka kanye neyokwelapha eyenziwe ngendwangu engalukiwe (njengezigqoko zokuhlinzwa, imaski yokuhlinzwa, i-PPE, i-apron yezokwelapha, izembozo zezicathulo njll.) sikhuphuke safika ku-10x saya ku-30x emazweni ahlukene.
Ngokusho kombiko wesitolo esikhulu kunazo zonke socwaningo lwemakethe emhlabeni i-“Research & Markets”, imakethe ye-Global Nonwoven Fabrics ibize amaRandi ayizigidigidi ezingama-44.37 ngo-2017 futhi kulindeleke ukuthi ifinyelele amaRandi ayizigidigidi ezingama-98.78 ngo-2026, ikhule ku-CAGR engu-9.3% ngesikhathi sokubikezela. Kucatshangwa futhi ukuthi imakethe ehlala isikhathi eside engalukiwe izokhula ngesilinganiso se-CAGR esiphezulu.
Kungani Kungalukwanga?
Ama-Nonwoven ayinto entsha, anobuciko, ayasebenziseka ngezindlela eziningi, anobuchwepheshe obuphezulu, avumelana nezimo, abalulekile futhi ayabola. Lolu hlobo lwendwangu lukhiqizwa ngqo ngemicu. Ngakho-ke asikho isidingo sezinyathelo zokulungisa intambo. Inqubo yokukhiqiza imfushane futhi ilula. Lapho ungakhiqiza khona amamitha ayi-5,00,000 endwangu elukiwe, kuthatha cishe izinyanga eziyi-6 (izinyanga ezi-2 zokulungiselela intambo, izinyanga ezi-3 zokuluka kuma-looms angu-50, inyanga e-1 yokuqeda nokuhlola), kuthatha izinyanga ezi-2 kuphela ukukhiqiza inani elifanayo lendwangu engalukiwe. Ngakho-ke, lapho izinga lokukhiqizwa kwendwangu elukiwe lingu-1 mete/minute kanti izinga lokukhiqizwa kwendwangu elukiwe lingu-2 metre/minute, kodwa izinga lokukhiqizwa kwendwangu engalukiwe lingu-100 metre/minute. Ngaphezu kwalokho, izindleko zokukhiqiza ziphansi. Ngaphandle kwalokho, indwangu engalukiwe ibonisa izakhiwo ezithile ezifana namandla aphezulu, ukukwazi ukuphefumula, ukumuncwa, ukuqina, isisindo esincane, amalangabi okuvimba, ukulahlwa njll. Ngenxa yazo zonke lezi zici ezimangalisayo, umkhakha wezindwangu uya ezindwangu ezingalukiwe.
Isiphetho:
Indwangu engalukiwe ivame ukubizwa ngokuthi ikusasa lemboni yezindwangu njengoba isidingo sayo somhlaba wonke kanye nokuguquguquka kwayo kuyanda kakhulu.
