Ijambo kudoda ntabwo risobanura "kuboha" cyangwa "kuboha", ariko umwenda ni mwinshi. Kudoda ni imyenda yimyenda ikorwa kuva fibre muguhuza cyangwa guhuza cyangwa byombi. Ntabwo ifite imiterere ya geometrike itunganijwe, ahubwo ni ibisubizo byumubano hagati ya fibre imwe nindi. Imizi nyirizina idoda irashobora kuba idasobanutse ariko ijambo "imyenda idoda" ryahimbwe mu 1942 kandi ryakorewe muri Amerika.
Imyenda idoda ikozwe muburyo 2 bwingenzi: iba yometseho cyangwa irahambiriwe. Umwenda udashushanyijeho udoda ubudodo ukorwa no gutondekanya impapuro zoroshye, hanyuma ugashyiramo ubushyuhe, ubushuhe & igitutu kugirango ugabanye & ugabanye fibre mumyenda yuzuye yuzuye idashobora gutemba cyangwa gucika. Ubundi hariho uburyo 3 bwingenzi bwo gukora imyenda ihujwe idoda imyenda: Yumye, Yumye kandi itaziguye. Muburyo bwumye bwo kudoda budoda, Urubuga rwa fibre rushyirwa murugoma hanyuma umwuka ushyushye uterwa kugirango uhuze fibre hamwe. Muri Wet-Laid idafite imyenda yo gukora imyenda, urubuga rwa fibre ruvanze numuti woroshye urekura ibintu bisa na kole bihuza fibre hanyuma urubuga rushyirwa kumisha. Muburyo butaziguye bwo gukora imyenda idoda, fibre izunguruka kumukandara wa convoyeur hanyuma kashe zomekwa kuri fibre, hanyuma zigakanda kugirango zihuze. (Mugihe cya fibre plastique, kole ntisabwa.)
Ibicuruzwa bidoda
Ahantu hose wicaye cyangwa uhagaze nonaha, reba gusa hirya no hino uzasanga byibuze umwenda umwe udoda. Imyenda idoda yinjira mumasoko atandukanye arimo ubuvuzi, imyenda, imodoka, kuyungurura, kubaka, geotextile no kurinda. Umunsi kuwundi gukoresha imyenda idoda iragenda yiyongera kandi utabifite ubuzima bwacu bwa none bwaba butumvikana. Ahanini hari ubwoko 2 bwimyenda idoda: Kuramba & Kujugunya. Hafi ya 60% yimyenda idoda iraramba kandi ikiruhuko 40% kirajugunywa.
Udushya duke mu nganda zidoda:
Inganda zidoda zidahwema gukungahazwa nigihe gisaba udushya kandi ibi bifasha no guteza imbere ubucuruzi.
Surfaceskins (Nonwovens Innovation & Research Institute- NIRI): Ni urugi rwa antibacterial gusunika amakariso & gukurura imashini zakozwe mu kwica mikorobe na bagiteri zabitswe mu masegonda y'ingenzi, hagati y'umukoresha umwe n'undi ukanyura mu muryango. Rero ifasha mukurinda ikwirakwizwa rya mikorobe na bagiteri mubakoresha.
Reicofil 5 (Reifenhäuser Reicofil GmbH & Co KG): Iri koranabuhanga ritanga tekinoroji yumurongo utanga umusaruro, wizewe kandi unoze ugabanya ibice bikomeye 90%; yongera umusaruro kugeza 1200 m / min; koroshya igihe cyo kubungabunga; bigabanya gukoresha ingufu.
Kuvugurura ™ Ifumbire ya Hernia (Shanghai Pine & Power Biotech): Nibikoresho bya electro-spun nano-igipimo cyiza cyane gishobora kwangirika cyane cyibinyabuzima kandi kikaba uburyo bwo gukura kwingirabuzimafatizo nshya, amaherezo ikabora ibinyabuzima; kugabanya igipimo cyibibazo nyuma yibikorwa.
Icyifuzo cy'isi yose:
Kugumana hafi yigihe kitavunika cyiterambere mumyaka 50 ishize, idoda irashobora kuba igice cyizuba riva mubucuruzi bwimyenda yisi yose hamwe ninyungu nyinshi kuruta ibindi bicuruzwa byimyenda. Isoko ryisi yose yimyenda idoda iyobowe nu Bushinwa hamwe n’isoko rya 35%, rikurikirwa n’Uburayi hamwe n’isoko rya 25%. Abakinnyi bakomeye muri uru ruganda ni AVINTIV, Freudenberg, DuPont na Ahlstrom, aho AVINTIV n’uruganda runini, aho isoko ry’umusaruro rigera kuri 7%.
Mu bihe byashize, hamwe n’ubwiyongere bwa virusi ya COVIC-19, gukenera isuku n’ibicuruzwa by’ubuvuzi bikozwe mu myenda idoda (nka: imipira yo kubaga, masike yo kubaga, PPE, imiti y’ubuvuzi, ibipfukisho by’inkweto n'ibindi) byiyongereye kugera kuri 10x kugeza 30x mu bihugu bitandukanye.
Raporo y’ububiko bunini bw’ubushakashatsi ku isoko “Ubushakashatsi & Isoko”, Isoko ry’imyenda ku isi ryinjije miliyari 44.37 z'amadolari muri 2017 kandi biteganijwe ko rizagera kuri miliyari 98.78 mu 2026, rikazamuka kuri CAGR ya 9.3% mu gihe cyateganijwe. Hafashwe kandi ko isoko rirambye idoda izakura hamwe nigipimo kinini cya CAGR.
Kuki idoda?
Nonwovens ni udushya, guhanga, guhuza byinshi, tekinoroji yo hejuru, guhuza n'imiterere, ingenzi kandi ibora. Ubu bwoko bwimyenda ikorwa muburyo butaziguye. Ntabwo rero hakenewe intambwe zo gutegura. Ibikorwa byo gukora ni bigufi & byoroshye. Aho ushobora kubyara metero 5.00.000 yimyenda iboshye, bisaba amezi 6 (amezi 2 yo gutegura umugozi, amezi 3 yo kuboha kumyenda 50, ukwezi 1 kurangiza & kugenzura), bisaba amezi 2 gusa kugirango ubyare ubwinshi imyenda idoda. Kubwibyo, aho umusaruro wimyenda iboshywe ari mete 1 / umunota naho umusaruro wimyenda uboshye ni metero 2 / umunota, ariko igipimo cyimyenda idoda ni metero 100 / umunota. Byongeye kandi ikiguzi cy'umusaruro ni gito. Byongeye kandi, imyenda idoda yerekana ibintu byihariye nkimbaraga zisumba izindi, guhumeka, kwinjirira, kuramba, uburemere bworoshye, gucana umuriro, kujugunywa nibindi. Kubera ibyo bintu byose biranga ibintu, urwego rwimyenda rugenda rwerekeza kumyenda idoda.
Umwanzuro:
Imyenda idoda ikunze kuvugwa ko ari ejo hazaza h’inganda z’imyenda nkuko ibyifuzo byabo ku isi & byinshi bihinduka gusa & hejuru.
