Ijambo "nonwoven" ntabwo risobanura "guboha" cyangwa "gufunze", ariko umwenda ni byinshi kurushaho. "Nonwoven" ni imiterere y'imyenda ikorwa mu buryo butaziguye mu migozi ivanze cyangwa ifatanye cyangwa byombi. Nta miterere ifite ya geometrike, ahubwo ni ingaruka z'isano iri hagati y'umugozi umwe n'undi. Imizi nyayo y'imigozi ishobora kuba idasobanutse neza ariko ijambo "imyenda idafunze" ryahimbwe mu 1942 kandi ryakorewe muri Leta Zunze Ubumwe za Amerika.
Imyenda idafunze ikorwa mu buryo bubiri bw'ingenzi: irafunze cyangwa irafunze. Imyenda idafunze ikorwa hakoreshejwe gushyira impapuro ntoya, hanyuma igashyirwamo ubushyuhe, ubushuhe n'igitutu kugira ngo igabanuke kandi ikandagire imigozi mu gitambaro kinini gipfundikiye kitazasaza cyangwa ngo gishwanyagurike. Nanone hari uburyo butatu bw'ingenzi bwo gukora imyenda idafunze ipfunze: Dry Laid, Wet Laid & Direct Spun. Mu buryo bwo gukora imyenda idafunze ipfunze, urusobe rw'imigozi rushyirwa mu ngoma hanyuma umwuka ushyushye ugashyirwamo kugira ngo imigozi ifatanye. Mu buryo bwo gukora imyenda idafunze ipfunze ipfunze, urusobe rw'imigozi ruvangwa n'ikintu cyoroshye gisohora ikintu gisa n'ubudozi buhuza imigozi hanyuma ubudozi bukarunduka. Mu buryo bwo gukora imyenda idafunze ipfunze ipfunze, imigozi ipfunze ku mukandara wo kohereza hanyuma kole igashyirwa ku migozi, hanyuma igakanda kugira ngo ihuze. (Mu gihe cy'imigozi ya thermoplastic, kole ntikenewe.)
Ibikoresho Bidaboshye
Aho waba wicaye cyangwa uhagaze hose, reba hirya no hino maze uhite ubona nibura umwenda umwe utari uwo kuboha. Imyenda idaboha yinjira mu masoko menshi arimo ay’ubuvuzi, imyenda, imodoka, kuyungurura, ubwubatsi, imitako yo mu bwoko bwa geotextile n’iy’uburinzi. Umunsi ku wundi ikoreshwa ry’imyenda idaboha ririyongera kandi iyo bitabaho ubuzima bwacu bwa none bwaba butoroshye gusobanukirwa. Muri make hari ubwoko bubiri bw’imyenda idaboha: Iramba & Ijugunywa. Hafi 60% by’imyenda idaboha iraramba naho indi 40% ni iyo gutabwa.
Udushya duke mu nganda zidakora imyenda:
Inganda zidakora akazi ko kudoda zihora zikungahazwa n'udushya dutwara igihe kinini, kandi ibi binafasha guteza imbere ubucuruzi.
Surfaceskins (Ikigo cy’Ubushakashatsi n’Ibitaro Bidafite Udushya- NIRI): Ni udukoresho two gusunika inzugi dukoresha imiti irwanya bagiteri n’imifatabuguzi byakozwe kugira ngo byice mikorobe n’udukoko twangiritse mu masegonda make, hagati y’umukoresha n’undi unyura mu muryango. Bityo bifasha mu gukumira ikwirakwira ry’udukoko n’udukoko mu bakoresha.
Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Iri koranabuhanga ritanga ikoranabuhanga ritanga umusaruro mwinshi, ryizewe kandi rikora neza, rigabanya ibice bikomeye ku kigero cya 90%; ryongera umusaruro kugeza kuri 1200 m/min; ryoroshya igihe cyo kubungabunga; rigabanya ikoreshwa ry'ingufu.
Remodelling™ Compound Hernia Patch (Shanghai Pine & Power Biotech): Ni agace gato gakozwe mu buryo bw'amashanyarazi gashobora gukururwa n'uturemangingo tw'umubiri kandi gafasha uturemangingo dushya gukura, amaherezo kagatuma habaho kwangirika kw'uturemangingo; kagabanya umuvuduko w'ibibazo nyuma yo kubagwa.
Ibikenewe ku Isi:
Mu gihe cy’imyaka 50 ishize, idafite imyenda ishobora kuba igice cy’inganda zikora imyenda ku isi gifite inyungu nyinshi kurusha ibindi bicuruzwa by’imyenda. Isoko ry’imyenda idakozwe ku ruhu riyobowe n’Ubushinwa bufite isoko rya hafi 35%, rigakurikirwa n’Uburayi bufite isoko rya hafi 25%. Abakinnyi bakomeye muri uru rwego ni AVINTIV, Freudenberg, DuPont na Ahlstrom, aho AVINTIV ari yo nganda nini, ifite isoko ry’umusaruro rya hafi 7%.
Mu minsi ishize, bitewe n’ubwiyongere bw’abarwayi ba COVIC-19, icyifuzo cy’isuku n’ibikoresho by’ubuvuzi bikozwe mu mwenda udafunze (nk’ingofero zo kubaga, udupfukamunwa two kubaga, ibikoresho byo kwikingira, apron yo kwa muganga, udupfukamunwa tw’inkweto n’ibindi) cyariyongereye cyane kigera ku nshuro 10 kigera kuri 30 mu bihugu bitandukanye.
Nk’uko raporo y’iduka rinini ku isi rikora ubushakashatsi ku isoko “Research & Markets” ibivuga, isoko ry’ibicuruzwa bitaboshye ku isi ryari rifite miliyari 44.37 z’amadolari mu 2017 kandi biteganijwe ko rizagera kuri miliyari 98.78 z’amadolari mu 2026, rikazazamuka ku kigero cya CAGR cya 9.3% mu gihe cy’iteganyagihe. Bivugwa kandi ko isoko rirambye ritaboshye rizakura ku kigero cya CAGR kiri hejuru.
Kuki bitaboshywe?
Ibitambaro bidafite ubudodo ni udushya, bihanga udushya, bifite uburyo bwinshi, ikoranabuhanga rihanitse, bihindura imiterere, ni ingenzi kandi birabora. Ubu bwoko bw'imyenda bukorwa mu buryo butaziguye mu ndodo. Bityo nta mpamvu yo gutegura ubudodo. Uburyo bwo kubikora ni bugufi kandi bworoshye. Aho gukora metero 5.00.000 z'imyenda iboshye, bifata amezi agera kuri 6 (amezi 2 yo gutegura ubudodo, amezi 3 yo kuboha ku mashini 50, ukwezi 1 ko kurangiza no kugenzura), bifata amezi 2 gusa gukora ingano imwe y'imyenda idafite ubudodo. Kubwibyo, aho igipimo cyo gukora igitambaro gikozwe ari metero 1 ku munota kandi igipimo cyo gukora igitambaro gikozwe ari metero 2 ku munota, ariko igipimo cyo gukora igitambaro kidafite ubudodo ni metero 100 ku munota. Byongeye kandi, ikiguzi cyo gukora ni gito. Byongeye kandi, igipimo cyo gukora igitambaro kidafite ubudodo gifite imiterere yihariye nko gukomera cyane, guhumeka neza, gukurura, kuramba, uburemere bworoshye, gutinza umuriro, guta ibintu nibindi. Kubera ibi bintu byose bitangaje, urwego rw'imyenda rurimo kwerekeza ku myenda idafite ubudodo.
Umwanzuro:
Imyenda idaboshye ikunze kuvugwa ko ari yo hazaza h’inganda z’imyenda kuko ibyo ikenera ku isi yose kandi ikaba ifite ubushobozi bwo gukora ibintu bitandukanye birimo kwiyongera cyane.
