Igama elithi nonwoven alithethi “olukiweyo” okanye “olukiweyo”, kodwa ilaphu alithethi okungaphezulu koko. I-Non-woven sisakhiwo selaphu esenziwe ngokuthe ngqo kwiifayibha ngokubopha okanye ngokunxibelelanisa okanye zombini. Ayinaso isakhiwo esicwangcisiweyo sejometri, kunoko sisiphumo sobudlelwane phakathi kwefayibha enye nenye. Iingcambu zokwenyani ze-nonwoven zisenokungacaci kodwa igama elithi “nonwoven fabric” laqanjwa ngo-1942 kwaye lenziwa eMelika.
Amalaphu angalukwanga enziwa ngeendlela ezimbini eziphambili: ayanqunyulwa okanye ayaxhunywa. Ilaphu elingalukwanga eliqunyiweyo lenziwa ngokubeka amashiti amancinci, emva koko kusetyenziswe ubushushu, ukufuma kunye noxinzelelo ukuze kuncitshiswe kwaye kucinezelwe imicu ibe ngelaphu eliqinileyo elixutyiweyo elingazukuqhekeka okanye liqhekeke. Kwakhona kukho iindlela ezintathu eziphambili zokwenza amalaphu angalukwanga aqunyiweyo: I-Dry Laid, i-Wet Laid kunye ne-Direct Spun. Kwinkqubo yokwenza i-Dry Laid Non-woven Fabric, i-web yeefayibha ifakwa kwidrama kwaye umoya oshushu ufakwa ukuze kuhlanganiswe imicu. Kwinkqubo yokwenza i-Wet-Laid Non-woven Fabric, i-web yeefayibha ixutywa ne-solvent ethambileyo ekhupha into efana neglue edibanisa imicu kunye kwaye i-web ibekwe ukuze yome. Kwinkqubo yokwenza i-Direct Spun Non-woven Fabric, imicu ijikeleziswa kwibhanti yokuhambisa kwaye iiglu zitshizwa kwimicu, emva koko zicinezelwe ukuze ziqhagamshelane. (Kwimeko yemicu ye-thermoplastic, akufuneki iglu.)
Iimveliso Ezingalukwanga
Naphi na apho uhleli khona okanye umi khona ngoku, jonga nje uze ufumane ubuncinane ilaphu elinye elingalukwanga. Amalaphu angalukwanga angena kwiimarike ezahlukeneyo kuquka ezonyango, iimpahla, iimoto, ukuhluza, ulwakhiwo, ii-geotextiles kunye nokukhusela. Imihla ngemihla ukusetyenziswa kwelaphu elingalukwanga kuyanda kwaye ngaphandle kwazo ubomi bethu bangoku bebuya kuba yinto engaqondakaliyo. Ngokusisiseko kukho iintlobo ezimbini zelaphu elingalukwanga: Elihlala ixesha elide kunye neLilahlayo. Malunga ne-60% yelaphu elingalukwanga lihlala ixesha elide kwaye amanye ama-40% alahlwa.
Zimbalwa Izinto Ezintsha Kwishishini Elingalukwanga:
Ishishini elingalukwanga lihlala lityetyiswa ziindlela ezintsha ezifuna ixesha elininzi kwaye oku kunceda ekuphuculeni amashishini.
IiSurfaceskins (iNonwovens Innovation & Research Institute- NIRI): Zii-antibacterial door pushing pads kunye neziphatho zokutsala ezenzelwe ukubulala iintsholongwane kunye neebhaktiriya ezigciniweyo kwimizuzwana ebalulekileyo, phakathi komnye umsebenzisi nomnye odlula emnyango. Ngaloo ndlela inceda ukuthintela ukusasazeka kweentsholongwane kunye neebhaktiriya phakathi kwabasebenzisi.
I-Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Le teknoloji inika ubuchwepheshe bomgca obuvelisa kakhulu, obuthembekileyo nobusebenzayo obunciphisa iziqwenga ezinzima ngama-90 ekhulwini; yonyusa imveliso ukuya kuthi ga kwi-1200 m/min; yenza kube lula ixesha lokulungisa; inciphisa ukusetyenziswa kwamandla.
I-Remodelling™ Compound Hernia Patch (Shanghai Pine & Power Biotech): Yi-electro-spun nano-scale patch ekwaziyo ukufunxwa ngexabiso eliphantsi kwaye isebenza njengendawo yokukhula kweeseli ezintsha, ekugqibeleni i-biodegrading; inciphisa izinga leengxaki emva kotyando.
Imfuno Yehlabathi:
Igcina phantse ixesha lokukhula elingaphazanyiswanga kwiminyaka engama-50 edlulileyo, i-nonwoven ingaba yinxalenye yokuphuma kwelanga kwishishini lempahla yelaphu lehlabathi elinenzuzo ephezulu kunayo nayiphi na eminye imveliso yelaphu. Imarike yehlabathi yelaphu elingalukwanga ikhokelwa yiTshayina enesabelo semarike esimalunga ne-35%, ilandelwe yiYurophu enesabelo semarike esimalunga ne-25%. Abadlali abaphambili kweli shishini yi-AVINTIV, iFreudenberg, iDuPont kunye ne-Ahlstrom, apho i-AVINTIV ingumvelisi omkhulu, onesabelo semarike yemveliso esimalunga ne-7%.
Kutshanje, ngenxa yokwanda kwamatyala e-COVIC-19, imfuno yococeko kunye neemveliso zonyango ezenziwe ngelaphu elingalukwanga (ezifana: iikepusi zotyando, iimaski zotyando, ii-PPE, i-apron yezonyango, izigqubuthelo zezihlangu njl.njl.) inyuke yaya kuthi ga kwi-10x ukuya kwi-30x kumazwe ahlukeneyo.
Ngokwengxelo yevenkile yophando lwemarike enkulu kwihlabathi "uPhando kunye neeMarike", imakethi yeGlobal Nonwoven Fabrics ibize i-$44.37 yeebhiliyoni ngo-2017 kwaye kulindeleke ukuba ifikelele kwi-$98.78 yeebhiliyoni ngo-2026, ikhule kwi-CAGR ye-9.3% ngexesha lexesha eliqikelelweyo. Kwakhona kucingelwa ukuba imakethi ehlala ixesha elide engalukwanga iya kukhula ngesantya esiphezulu se-CAGR.
Kutheni Kungelukwanga?
Ii-Nonwovens zintsha, zinobuchule, ziguquguqukayo, zinobuchwepheshe obuphezulu, ziyaguquguquka, zibalulekile kwaye ziyabola. Olu hlobo lwelaphu lwenziwa ngokuthe ngqo kwiifayibha. Ngoko ke akukho mfuneko yamanyathelo okulungiselela intambo. Inkqubo yokuvelisa imfutshane kwaye ilula. Apho kufuneka kuvele khona i-5,00,000 yeemitha zelaphu elilukiweyo, kuthatha malunga neenyanga ezi-6 (iinyanga ezi-2 zokulungiselela intambo, iinyanga ezi-3 zokulukwa kwi-50 looms, inyanga e-1 yokugqiba nokuhlola), kuthatha iinyanga ezi-2 kuphela ukuvelisa ubungakanani obufanayo belaphu elilukiweyo. Ke ngoko, apho izinga lokuvelisa ilaphu elilukiweyo liyi-1 mete/ngomzuzu kwaye izinga lokuvelisa ilaphu elilukiweyo liyi-2 metre/ngomzuzu, kodwa izinga lokuvelisa ilaphu elilukiweyo liyi-100 metre/ngomzuzu. Ngaphezu koko, iindleko zokuvelisa ziphantsi. Ngaphandle koko, ilaphu elilukiweyo libonisa iimpawu ezithile ezifana namandla aphezulu, ukuphefumla, ukufunxa, ukuqina, ubunzima obuphantsi, amalangabi abambezelayo, ukulahlwa njl. Ngenxa yazo zonke ezi mpawu zimangalisayo, icandelo lelaphu lisiya kwilaphu elilukiweyo.
Isiphelo:
Ilaphu elingalukwanga lidla ngokuthiwa likamva leshishini lelaphu njengoko imfuno yalo yehlabathi kunye nokuguquguquka kwalo kusanda ngokwanda.
