Izwi rekuti nonwoven harirevi "kurukwa" kana "kurukwa", asi jira racho rinotopfuura ipapo. Non-woven chimiro chemucheka chinogadzirwa zvakananga kubva mushinda nekubatanidza kana kupindirana kana zvese zviri zviviri. Harina chimiro chakarongeka chejometri, asi imhedzisiro yehukama huripo pakati peshinda imwe neimwe. Midzi chaiyo yeshinda dzisina kurukwa ingasave yakajeka asi izwi rekuti "machira asina kurukwa" rakatangwa muna 1942 uye rakagadzirwa muUnited States.
Machira asina kurukwa anogadzirwa nenzira mbiri huru: anotemwa kana kuti anosungwa. Machira asina kurukwa anogadzirwa nekuisa machira matete, wozoisa kupisa, hunyoro uye kumanikidza kuti ateteke uye adzvanye machira kuita jira gobvu rakamanikana risingazotsvedze kana kuparara. Zvakare kune nzira nhatu huru dzekugadzira machira asina kurukwa akabatana: Dry Laid, Wet Laid & Direct Spun. Mukugadzira machira asina kurukwa akaomeswa, dandemutande remachira rinoiswa mudhiramu uye mhepo inopisa inopinzwa kuti isunge machira pamwe chete. Mukugadzira machira asina kurukwa akaomeswa, dandemutande remachira rinosanganiswa nechinonyungudutsa chinoburitsa chinhu chakaita seglue chinosunga machira pamwe chete uye dandemutande rinoiswa kuti riome. Mukugadzira machira asina kurukwa akaomeswa zvakananga, machira anosvetwa kubhandi remuchina wekutakura uye maglue anopfapfaidzwa kumafiber, ayo anozodzvanywa kuti abatane. (Kana paine mafiber ethermoplastic, glue haidiwe.)
Zvigadzirwa Zvisina Kurukwa
Chero kwaunenge wakagara kana kumira izvozvi, ingotarisa-tarisa wobva washamisika kuti uchawana jira rimwe chete risingarukwe. Machira asina kurukwa anopinda mumisika yakasiyana-siyana kusanganisira yezvekurapa, zvipfeko, mota, kusefa, kuvaka, geotextiles uye yekudzivirira. Zuva nezuva kushandiswa kwejira risina kurukwa kuri kuwedzera uye pasina iwo hupenyu hwedu hwazvino hwaizova husinganzwisisike. Chaizvoizvo kune mhando mbiri dzejira risina kurukwa: Rinogara & Rinoraswa. Inenge 60% yejira risina kurukwa inogara kwenguva refu uye mamwe 40% anoraswa.
Kuvandudzwa Kushoma Muindasitiri Isina Kurukwa:
Maindasitiri asina kurukwa anogara achipfumiswa nekugadzira zvinhu zvitsva zvinoda nguva uye izvi zvinobatsirawo kusimudzira mabhizinesi.
Surfaceskins (Nonwovens Innovation & Research Institute- NIRI): Ipurasitiki yekusunda magonhi inorwisa mabhakitiriya uye mibato yekudhonza yakagadzirwa kuuraya utachiona hwakachengetwa mumasekonzi akakosha, pakati pemushandisi mumwe nemumwe nemushandisi anotevera achipfuura nemusuwo. Saka zvinobatsira kudzivirira kupararira kwehutachiona nemabhakitiriya pakati pevashandisi.
Reicofil 5 (Reifenhäuser Reicofil GmbH & Co. KG): Iyi tekinoroji inopa tekinoroji yemitsetse inobereka zvakawanda, yakavimbika uye inoshanda zvakanaka iyo inoderedza zvidimbu zvakaoma ne90 muzana; inowedzera simba rinobuda kusvika 1200 m/min; inoita kuti nguva yekugadzirisa ive nyore; inoderedza kushandiswa kwesimba.
Remodelling™ Compound Hernia Patch (Shanghai Pine & Power Biotech): Ipatch yakagadzirwa nemagetsi uye inonyungudutswa nechinhu chinobatsira kupinza masero matsva, zvichizopedzisira zvaita kuti aora; zvichideredza huwandu hwematambudziko mushure mekuvhiyiwa.
Kudiwa Kwepasi Rose:
Zvichiramba zvichikura kwenguva yakareba mumakore makumi mashanu apfuura, nonwoven inogona kuva chikamu chinobuda pachena cheindasitiri yemachira pasi rose chine purofiti yakakwira kupfuura zvimwe zvigadzirwa zvemachira. Musika wepasi rose wemachira asina kurukwa unotungamirwa neChina ine mugove wemusika weinenge 35%, ichiteverwa neEurope ine mugove wemusika weinenge 25%. Vatambi vanotungamira muindasitiri iyi ndiAVINTIV, Freudenberg, DuPont naAhlstrom, uko AVINTIV ndiyo mugadziri mukuru, ine mugove wemusika weinenge 7%.
Munguva pfupi yapfuura, nekuwanda kwenyaya dzeCOVIC-19, kudiwa kwezvishandiso zvehutsanana nezvehutano zvakagadzirwa nejira risina kurukwa (senge: ngowani dzekuvhiya, masikirini ekuvhiya, PPE, apron yekurapa, machira ekuvhara shangu nezvimwewo) kwawedzera kusvika ka10 kusvika ka30 munyika dzakasiyana.
Sekureva kwemushumo wechitoro chikuru chekutsvaga musika pasi rose chinonzi "Research & Markets", musika weGlobal Nonwoven Fabrics wakaita $44.37 bhiriyoni muna 2017 uye unotarisirwa kusvika $98.78 bhiriyoni panosvika 2026, uchikura paCAGR ye9.3% panguva yekufanotaura. Zvinofungidzirwawo kuti musika unogara kwenguva refu usina kurukwa uchakura neCAGR yakakwira.
Sei Zvisina Kurukwa?
Machira asina kurukwa ane hunyanzvi, ane hunyanzvi, anoshanduka-shanduka, ane tekinoroji yepamusoro, anochinjika, akakosha uye anoora. Rudzi urwu rwejira rinogadzirwa zvakananga kubva kumafaibha. Saka hapana chikonzero chematanho ekugadzirira shinda. Maitiro ekugadzira ipfupi uye ari nyore. Kwekugadzira jira rakarukwa remamita 5,00,000, zvinotora mwedzi inosvika mitanhatu (mwedzi miviri yekugadzira shinda, mwedzi mitatu yekuruka pazvirukwa makumi mashanu, mwedzi mumwe wekupedzisa nekuongorora), zvinotora mwedzi miviri chete kugadzira huwandu hwakafanana hwejira risina kurukwa. Saka, kana huwandu hwekugadzira jira rakarukwa huri 1 mete/minute uye huwandu hwekugadzira jira rakarukwa huri 2 mete/minute, asi huwandu hwekugadzira jira risina kurukwa huri 100 mete/minute. Uyezve mutengo wekugadzira wakaderera. Kunze kweizvozvo, jira risina kurukwa rine hunhu hwakadai sesimba rakakwirira, kufema, kunyudzwa, kugara kwenguva refu, huremu hushoma, moto unodzima, kuraswa nezvimwe. Nekuda kwezvinhu izvi zvinoshamisa, chikamu chemachira chiri kufambira mberi kune machira asina kurukwa.
Mhedziso:
Machira asina kurukwa anowanzonzi ndiwo ramangwana reindasitiri yemachira sezvo kudiwa kwawo pasi rose uye kushandiswa kwawo kwakasiyana-siyana kuri kungowedzera zvakanyanya.
