Nonwoven jira ijira rakaita sejira rakagadzirwa kubva kune refu faibha, rakasungirirwa pamwechete nekemikari, mechanika, kupisa kana mushonga wekunyungudutsa. Izwi iri rinoshandiswa muindasitiri yekugadzira machira kuratidza machira, senge anonzwa, asina kurukwa kana kurukwa. Zvishandiso zvisina kurukwa kazhinji hazvina simba kunze kwekunge zvakasimbiswa kana kusimbiswa nerutsigiro. Mumakore achangopfuura, nonwovens ave imwe nzira ye polyurethane foam.
Muchikamu chino, tichaongorora tsanangudzo yemachira asina kuruka uye kupa mimwe mienzaniso. Pamusoro pezvo, isu tichagovana zvimwe zvinonakidza chokwadi pamusoro pemachira asiri akarukwa. Ngatitange!
Mune ino posvo isu tichafukidza:
Kuongorora Nyika yeMicheka isina kurukwa
Machira asina kuruka anotsanangurwa zvakanyanya seshizha kana webhu zvimiro zvinosungirirwa pamwechete nemakemikari, mechanika, kupisa, kana mushonga wekunyungudutsa. Machira aya anogadzirwa kubva kustaple faibha uye refu fiber anobatanidzwa kugadzira chinhu chaicho chisina kuruka kana kurukwa. Izwi rekuti "nonwoven" rinoshandiswa muindasitiri yekugadzira machira kuratidza machira akadai sekunzwa, asina kurukwa kana kurukwa.
Zvivakwa neMashandiro eMicheka isina kurukwa
Machira asina kuruka anogadzirwa kuti ape huwandu hwakasiyana hwemabasa uye zvivakwa, zvichiita kuti ive yakakodzera kune akasiyana mabasa. Zvimwe zvezvivakwa uye mabasa emachira asina kuruka anosanganisira:
- Kubvisa
- Cushioning
- mupise
- Flame retadancy
- Liquid repellency
- Resilience
- Nyoro
- Kuchengeta
- simba
- Stretch
- Washability
Kugadzira Matanho eMicheka isina kurukwa
Machira asina kuruka anogona kugadzirwa achishandisa nzira dzakasiyana siyana, kusanganisira:
- Bonding fibers zvakananga
- Entangling filaments
- Perforating porous sheets
- Kuparadzanisa plastiki yakanyungudutswa
- Kushandura mafiber kuita dandemutande risina kuruka
Kutsvaga Mhando Dzakasiyana dzeMicheka isina Kurukwa
Micheka isina-yakarukwa inoshandiswa zvakanyanya mumusika nhasi nekuda kwekusiyana-siyana uye nyore kugadzira. Iwo anogadzirwa nekubatanidza shinda pamwe chete pasina kuruka kana kuvakwa kwemaoko kunobatanidzwa. Muchikamu chino, tichaongorora mhando dzakasiyana dzemachira asina kurukwa anowanikwa mumusika uye mashandisirwo awo chaiwo.
Mhando dzeMicheka isina Kurukwa
Micheka isina-yakarukwa inogona kuiswa mumhando dzakasiyana zvichienderana nemidziyo inoshandiswa uye maitiro ekugadzira. Mamwe emhando huru dzemachira asiri akarukwa anosanganisira:
- Spunbond Non-Woven Fabric: Rudzi urwu rwejira risiri rakarukwa rinogadzirwa nekunyunguduka uye nekuburitsa polima kuita filaments yakanaka. Iyi filaments inobva yaiswa pasi pabhandi rekutakura uye inobatanidzwa pamwe chete uchishandisa simba rinopisa. Machira eSpunbond asiri akarukwa akasimba, matete, uye akanakira kushandiswa mukuvaka, kuchengetedza, uye hunyanzvi hwekushandisa.
- Meltblown Non-Woven Fabric: Rudzi urwu rwejira risiri rakarukwa rinogadzirwa pachishandiswa hunyanzvi hwakafanana sejira re spunbond risiri rakarukwa. Zvisinei, iyo filaments yakanyanya kupfupika uye yakaisvonaka, zvichiita kuti zvive nemucheka wakajeka uye wakafanana. Meltblown machira asiri akarukwa anowanzo kushandiswa mune zvekurapa uye zvehutsanana zvigadzirwa nekuda kwekugona kwavo kusefa kunze tudiki.
- Needle Punch Non-Woven Fabric: Rudzi urwu rwejira risiri rakarukwa rinogadzirwa nekupfuura faibha kuburikidza nenhevedzano yetsono dzinomanikidza mafiibhi kuti abatane uye abatane pamwechete. Machira etsono asina kurukwa akasimba, akasimba, uye akakwana kuti ashandiswe muzvigadzirwa zvinoda nzvimbo yakachena uye yakachengeteka.
- Wet Laid Non-Woven Fabric: Rudzi urwu rwejira risiri rakarukwa rinogadzirwa nekushandura machira echisikigo kana ekugadzira kuita slurry. Iyo slurry inozowaridzwa pabhandi rekutakura uye ichipfuura nemunhevedzano yema rollers kuti ibvise mvura yakawandisa. Machira akanyorova akaiswa asiri akarukwa anowanzo shandiswa mukugadzira mawipes, mafirita, uye zvimwe zvigadzirwa zvinoda chakapfava uye chinonwisa.
Kusarudza Mucheka Wakarurama Usina Kurukwa
Paunosarudza jira risina kugadzirwa, zvakakosha kufunga nezvekushandiswa kwakananga uye zvinodiwa nemushandisi wekupedzisira. Zvimwe zvinhu zvekufunga nezvazvo zvinosanganisira:
- Kusimba uye Kusimba: Mamwe marudzi emachira asina kuruka akasimba uye akasimba kupfuura mamwe, zvichiita kuti ave akakodzera kushandiswa mune zvigadzirwa zvinoda mwero wepamusoro wekusimba uye kusimba.
- Absorbency: Machira akanyorova akaiswa asiri akarukwa akanakira kushandiswa mune zvigadzirwa zvinoda mwero wepamusoro wekunyura, senge mapukuta nemasefa.
- Hutsanana uye Kuchengeteka: Machira etsono asina kurukwa akakodzera kushandiswa mune zvigadzirwa zvinoda nzvimbo yakachena uye yakachengeteka, senge zvigadzirwa zvekurapa uye zvehutsanana.
- Kupfava uye Nyaradzo: Meltblown machira asiri akarukwa akanakira kushandiswa mune zvigadzirwa zvinoda zvinhu zvakapfava uye zvakasununguka, senge manapukeni uye zvigadzirwa zvehutsanana hwevakadzi.
Iyo Nonwoven Fabric Inogadzirwa sei
Imwe nzira yakakurumbira yekugadzira jira risingarukwe ndeye spunbond process. Kuita uku kunosanganisira kuburitsa resin yepolymer kuburikidza nemuromo kugadzira filaments. Iyo filaments inozoiswa zvisina tsarukano pabhandi rinofamba, kwainosungirirwa pamwechete uchishandisa thermal kana kemikari bonding. Dandemutande rinenge rabuda reshinda rinobva rasungirirwa pamupumburu uye rinogona kugadziridzwazve kuita chigadzirwa chapera.
Meltblown Process
Imwe nzira yakajairika yekugadzira jira risingarukwa ndeye meltblown process. Kuita uku kunosanganisira kuburitsa resin yepolymer kuburikidza nemuromo wobva washandisa mweya unopisa kutambanudza nekupwanya mafilaments kuita fiber yakanyanya kunaka. Mafiibha acho anobva aiswa zvisina tsarukano pabhandi rinofamba, kwaanosungirirwa pamwechete achishandisa thermal bonding. Dandemutande rinenge rabuda reshinda rinobva rasungirirwa pamupumburu uye rinogona kugadziridzwazve kuita chigadzirwa chapera.
Drylaid Process
Iyo drylaid process ndiyo imwe nzira yekugadzira jira risiri rakarukwa. Izvi zvinosanganisira kuisa fiber pasi pabhandi rinofamba uye kushandisa karenda kusunga fiber pamwe chete. Iyo fiber inogona kugadzirwa kubva kumhando dzakasiyana-siyana, kusanganisira donje, uye jira rinoguma rinogona kushandiswa mune zvakasiyana-siyana zvekushandisa.
mhedziso
Saka, kusarukwa zvinoreva jira risina kurukwa. Inogona kugadzirwa neshinda kana purasitiki uye inogona kushandiswa kune zvakasiyana-siyana. Chinhu chikuru chekugadzira zvinhu zvinoda kuve zvakapfava kana kunyura. Saka, nguva inotevera yaunoda kutenga chimwe chinhu, iwe unogona kuzvisarudzira iwe kana isiri-yakarukwa iri sarudzo yakanaka. Unogona kushamiswa nezvaunogona kuwana!
Ini ndini Joost Nusselder, muvambi weZvishandiso Chiremba, mushambadzi wemukati, uye baba. Ini ndinoda kuyedza michina mitsva, uye pamwe nechikwata changu ndanga ndichigadzira zvakadzama blog zvinyorwa kubva 2016 kubatsira vaverengi vakavimbika nematurusi & matipi ekugadzira.
