Mawu oti nonwoven samatanthauza "kuluka" kapena "kulukana", koma nsaluyo ndi yosiyana kwambiri. Non-woven ndi kapangidwe ka nsalu komwe kamapangidwa mwachindunji kuchokera ku ulusi mwa kulumikizana kapena kulumikizidwa kapena zonse ziwiri. Sili ndi kapangidwe kolinganizika bwino, koma ndi zotsatira za ubale pakati pa ulusi umodzi ndi unzake. Mizu yeniyeni ya nonwoven singamveke bwino koma mawu oti "nonwoven fairs" adapangidwa mu 1942 ndipo adapangidwa ku United States.
Nsalu zosalukidwa zimapangidwa m'njira ziwiri zazikulu: zimadulidwa kapena zimalumikizidwa. Nsalu yosalukidwa yopangidwa ndi felt imapangidwa poika mapepala opyapyala, kenako nkupaka kutentha, chinyezi ndi kukakamiza kuti zichepetse ndikukanikiza ulusi kukhala nsalu yokhuthala yopapatiza yomwe sidzaphulika kapena kusweka. Palinso njira zitatu zazikulu zopangira nsalu zosalukidwa zolumikizidwa: Dry Laid, Wet Laid & Direct Spun. Mu njira yopangira Nsalu Zosalukidwa ndi Dry Laid, ukonde wa ulusi umayikidwa mu ng'oma ndipo mpweya wotentha umalowetsedwa kuti ulumikize ulusi pamodzi. Mu njira yopangira Nsalu Zosalukidwa ndi Wet-Laid, ukonde wa ulusi umasakanizidwa ndi solvent yofewa yomwe imatulutsa chinthu chonga guluu chomwe chimalumikiza ulusi pamodzi kenako ukonde umayikidwa kuti uume. Mu njira yopangira Nsalu Zosalukidwa ndi Direct Spun, ulusi umapindidwa ku lamba wonyamulira ndipo guluu umapopedwa ku ulusi, womwe umakanikizidwa kuti ugwirizane. (Ngati pali ulusi wa thermoplastic, guluu siwofunikira.)
Zogulitsa Zopanda Ulusi
Kulikonse komwe mukukhala kapena kuyimirira pakali pano, ingoyang'anani mozungulira ndipo mudzapeza nsalu imodzi yosaluka. Nsalu zosaluka zimalowa m'misika yosiyanasiyana kuphatikizapo zamankhwala, zovala, magalimoto, zosefera, zomangamanga, zomangira ndi zoteteza. Tsiku ndi tsiku kugwiritsa ntchito nsalu zosaluka kukuchulukirachulukira ndipo popanda iwo moyo wathu wamakono ukanakhala wosamveka bwino. Kwenikweni pali mitundu iwiri ya nsalu zosaluka: Yolimba & Yotayidwa. Pafupifupi 60% ya nsalu zosaluka ndi yolimba ndipo zina 40% ndi zotayidwa.
Zatsopano Zochepa mu Makampani Osalukidwa:
Makampani Osalukidwa nthawi zonse amalimbikitsidwa ndi zatsopano zomwe zimafuna nthawi yambiri ndipo izi zimathandizanso kupititsa patsogolo mabizinesi.
Surfaceskins (Nonwovens Innovation & Research Institute- NIRI): Ndi ma pad opondereza zitseko ndi zogwirira zokokera zomwe zimapangidwa kuti ziphe majeremusi ndi mabakiteriya omwe asungidwa mkati mwa masekondi ofunikira, pakati pa wogwiritsa ntchito m'modzi ndi wotsatira amene akudutsa pakhomo. Motero zimathandiza kupewa kufalikira kwa majeremusi ndi mabakiteriya pakati pa ogwiritsa ntchito.
Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Ukadaulo uwu umapereka ukadaulo wothandiza kwambiri, wodalirika komanso wogwira ntchito bwino womwe umachepetsa zidutswa zolimba ndi 90 peresenti; umawonjezera mphamvu yotulutsa mpaka 1200 m/min; umathandizira nthawi yokonza; umachepetsa kugwiritsa ntchito mphamvu.
Remodelling™ Compound Hernia Patch (Shanghai Pine & Power Biotech): Ndi chigamba cha nano-scale chomwe chimapangidwa ndi electro-spun chomwe chimayamwa bwino kwambiri komanso chimagwira ntchito ngati malo okulira maselo atsopano, zomwe pamapeto pake zimawonongeka; kuchepetsa kuchuluka kwa mavuto omwe amabwera pambuyo pa opaleshoni.
Kufunika kwa Padziko Lonse:
Pokhala ndi nthawi yopitilira kukula kwa zaka 50 zapitazi, nsalu zopanda nsalu zitha kukhala gawo lotsogola kwambiri la makampani opanga nsalu padziko lonse lapansi omwe ali ndi phindu lalikulu kuposa zinthu zina zilizonse za nsalu. Msika wapadziko lonse wa nsalu zopanda nsalu umatsogozedwa ndi China yokhala ndi gawo la msika pafupifupi 35%, kutsatiridwa ndi Europe yokhala ndi gawo la msika pafupifupi 25%. Osewera otsogola mumakampani awa ndi AVINTIV, Freudenberg, DuPont ndi Ahlstrom, komwe AVINTIV ndiye wopanga wamkulu kwambiri, wokhala ndi gawo la msika pafupifupi 7%.
Posachedwapa, chifukwa cha kuchuluka kwa milandu ya COVIC-19, kufunika kwa zinthu zaukhondo ndi zamankhwala zopangidwa ndi nsalu zosalukidwa (monga: zipewa za opaleshoni, masks opareshoni, PPE, apron yachipatala, zophimba nsapato ndi zina zotero) kwawonjezeka kufika pa 10 mpaka 30 m'maiko osiyanasiyana.
Malinga ndi lipoti la sitolo yayikulu kwambiri padziko lonse yofufuza za msika "Research & Markets", msika wapadziko lonse wa Nonwoven Fabrics udachita $44.37 biliyoni mu 2017 ndipo ukuyembekezeka kufika $98.78 biliyoni pofika chaka cha 2026, kukula pa CAGR ya 9.3% panthawi yomwe yanenedweratu. Akuganizanso kuti msika wolimba wosaluka udzakula ndi CAGR yokwera.
N’chifukwa Chiyani Sizolukidwa?
Nsalu zopanda ulusi ndi zatsopano, zopanga, zosinthasintha, zaukadaulo wapamwamba, zosinthika, zofunika komanso zowola. Nsalu yamtunduwu imapangidwa mwachindunji kuchokera ku ulusi. Chifukwa chake palibe chifukwa chokonzekera ulusi. Njira yopangira ndi yaifupi komanso yosavuta. Kumene mungapangire nsalu yoluka ya mamita 5,00,000, zimatenga pafupifupi miyezi 6 (miyezi iwiri yokonzekera ulusi, miyezi itatu yolukira pa nsalu 50, mwezi umodzi womaliza ndikuwunika), zimatenga miyezi iwiri yokha kupanga nsalu yofanana. Chifukwa chake, pomwe kuchuluka kwa nsalu yolukidwa ndi mita imodzi pa mphindi ndipo kuchuluka kwa nsalu yolukidwa ndi mita ziwiri pa mphindi, koma kuchuluka kwa nsalu yopanda ulusi ndi mita 100 pa mphindi. Kuphatikiza apo, mtengo wopangira ndi wotsika. Kupatula apo, nsalu yopanda ulusi yomwe ili ndi makhalidwe enaake monga mphamvu yayikulu, kupuma, kuyamwa, kulimba, kulemera kopepuka, malawi oletsa, kutaya ndi zina zotero. Chifukwa cha zinthu zodabwitsa zonsezi, gawo la nsalu likupita ku nsalu zopanda ulusi.
Mapeto:
Nsalu yosalukidwa nthawi zambiri imanenedwa kuti ndi tsogolo la mafakitale a nsalu chifukwa kufunika kwawo padziko lonse lapansi komanso kusinthasintha kwawo kukukulirakulira.
