Unoziva zvikonzero nei machira asina kurukwa achishandiswa mune zvekurapa?

Nonwovens ave achishandiswa muindasitiri yezvokurapa kubvira Hondo Yenyika II, apo nhamba huru yezvigadzirwa zvekurapa zvaidiwa. Nonwovens aionekwa seanonyanya kushanda mabhakitiriya barriers zvinhu mumishumo yakawanda yakadhindwa. Zvakaonekwa zvakare kuti vakaderedza kusvibiswa kwemhepo zviri nani pane flax. Zvisizvo zvakarukwa zvakakura zvikuru, uye nhasi zviri kukunda dzimwe dzakarukwa muzvinhu zvakawanda, zvinosanganisira mutengo, kushanda zvakanaka, uye zvokurasa. Muzvipatara, kutapuriranwa kunongogara kuri imwe yenyaya huru. Chikonzero chikuru cheizvi ndiko kugara uchishandiswa kwemasiki akarukwa, gown, uye zvimwe zvinhu zvemhando yakafanana, izvo zvinogona kusvibiswa nekuparadzira mabhakitiriya. Kuunzwa kwemanonwovens kwakabatsira mukugadzirwa kwezvimwe zvinodhura, zvinoraswa.

Sei uchienda kune mask yekuvhiya pasina kuruka? Muzvipatara, masikisi ekuvhiya asina kurukwa inzira yakakosha yekuchengetedza varwere nevashandi vekurapa. Masiki emhando yepamusoro akakosha kune mamaneja ezvivakwa uye vachengeti vane hunyanzvi vanotenga izvi zvakakosha zvekuchengetedza. Zvishandiso zvinoshandiswa mumasiki aya zvinofanirwa kumisa mabhakitiriya kubva kumuromo wechiremba kuenda kumuromo wevarwere uye zvinopesana nekuda kwehukuru hudiki hwebhakitiriya. Uyezve, iyo mask inoda kudzivirira mushandisi kubva kumamorekuru akakura munzvimbo yekuvhiya, sekuparadzira ropa. Nekudaro, chii chinoita kuti rudzi urwu rwemasiki anoraswa afarirwe kune anogona kushandiswazve machira masiki evashandi vehutano?

Humwe hunhu hwechinyakare microporous machira akafananidzwa neasina woven mask media muchidzidzo chakaburitswa mu Journal of Academia uye Industrial Research: mechanical resistance, linting, bacteria permeability, liquid permeability, flexibility, drapeability, and comfort. Machira asina kuruka anoita zvirinani pane mamwe machira muzvikamu zvina zvezvinomwe, uye anokwikwidza mune maviri emamwe matatu. Ndeapi mamwe mabhenefiti ane kugadzira iyo isiri-yakarukwa mask yekuvhiya ine?

1. Izvo zvinokosha zvehupenyu hwezuva nezuva.

MuUnited States moga, kune zvipatara zvinosvika 5,686 zvine mibhedha inoda kusvika miriyoni imwe. Iyi inhamba inokatyamadza kana iwe uchifunga zvinoraswa zvisina wovens. Mask yekuvhiya inoraswa chinhu chinodiwa chekutarisira. Kwemakore akawanda, mamasiki ekutanga akagadzirwa kubva kune zvigadzirwa zvine hunyanzvi hunhu anogona kutengeswa sezvinhu.

2. Akakwirira zvikuru kupfuura machira akarukwa munzira dzakawanda.

Ivo vane hunyanzvi hwekusefa kwebhakitiriya, huwandu hwekuyerera kwemhepo, uye kuderedzwa kwemitengo yekugadzira mukuwedzera kune yakambotaurwa maitiro.

3. Izvo zvinoshanda kune vashandi vechipatara.

Mushure mekushandiswa, masks ekuvhiya anoraswa asina kurukwa anoiswa pasuru, ovharirwa, uye anoraswa ipapo ipapo. Machira akashandiswa haafanire kuchengetwa, uye vashandi vemuchipatara havafanire kuchenesa, kuvharisa, nekuarongedza kuti azoashandisa mune ramangwana. Ndezvipi zvikamu zvinopinda mukugadzira mask yekuvhiya isiri yakarukwa? Kune mhando mbiri dzemafibhi anoshandiswa mumasikisi ekuvhiya asiri akarukwa: ekugadzira uye shinda dzechisikigo. Mafibhi echisikigo anoshandiswa ndeye rayon, donje, uye pulp yehuni. Zvakanakira zvehuni pulp zvinosanganisira mutengo wakaderera, vhoriyamu diki, uye kunyura kwemvura kwakasimba. Maronda anogona kupfekedzwa zvakananga nekotoni kana rayon. Iwo epamusoro nonwovens ane yakanaka yekunyudza mvura.

Kufema kwakanakisa, kugadzikana kwechimiro chepamusoro, tembiricha inoshanda kwazvo, kudhirowa kwakanakisa, kuenderana, kumira zvakanaka kwekupisa, kunaka kwekuchengetedza mvura, uye kwete-allergenic uye isingatsamwire fibers ndezvimwe zvezvikonzero nei faibha dzechisikigo dzichigadzira masiki anoraswa muindasitiri yehutano. Mafibisi ekugadzira anowanzo shandiswa muchishandiso ichi ipolyester kana yakakwira simba, kurerutsira kwesterilization, uye michina yemagetsi yakakosha; bicomponent fibers, iyo inoshandiswa zvakanyanya pakupisa kubatanidza uye kuwedzera kushanda; uye polypropylene, ine yakanakisa rheological properties, hydrophobicity, uye yakaderera mutengo. Pamwe chete nehumwe huzhinji hunodiwa hunhu, mafivha ekugadzira anofunga kusimba kwechigadzirwa, kunyungudutsa kwesolvent, static dissipation, nezvimwe. Iyo masiki yekuvhiya isiri yakarukwa inoda mafivha ekugadzira ane zvinotevera zvimiro: hydrophobicity, kukwanisa kutenga, kusimba kwepamusoro, kushomeka, uye kuraswa kwakachengeteka. Ndeapi maitiro anobatanidzwa mukugadzira?

Vane kugadzikana muhukuru uye vakapfava uye vane porous. Pamusoro pezvo, spunbonding inowanzo shandiswa muzvinhu zvakaita sembatya dzinoraswa, musoro, zvivharo zveshangu, masks ekumeso, uye machira. Hunhu hwakasiyana hwewebhu hunogona kuwanikwa kuburikidza nekushandisa hunyanzvi hwakasiyana senge pakaoma kuisa, kunyorova kuisa, uye makadhi, zvichienderana nezvinhu zvakaita sehukobvu hwewebhu hunodiwa uye kukurumidza kwehunyanzvi hwekubatanidza. Kadhi inogona kushandiswa kugadzira mawebhu akareruka ezvigadzirwa zvehutsanana uye zvehunyanzvi. Kadhi inogadzira zvinokurumidza, zvemhando yepamusoro mawebhu. Kune nzira dzakawanda dzekuita bonding, imwe yacho ndeyekupisa kusungirirana kwemafambo ekugadzira uye masanganiswa awo. Iyo tekinoroji yekubatanidza iyo iri kuwedzera nekukurumidza ndeye hydroenangling. Mune mask inoraswa, yakashandiswa chaizvo. Inonzwa senge machira uye yakanakira zvigadzirwa senge gauze, mapfekero, zvipfeko zvechipatara, nezvimwe zvinhu.

Kana ichienzaniswa neshinda dzekugadzira, mask yekupedzisira inoraswa inodhura zvakanyanya kunyangwe iine hunhu hwepamusoro. Kuti ivandudze kuchena kwayo uye, nekudaro, kugamuchirwa kwayo muzvikamu zvekurapa uye zvehutano, donje rinowanzoitwa mercerized uye bleached. Cotton's high dust content inoita kuti zviome zvakare. Pamusoro pezvo, magauni ekuvhiya, machira edonje, maketeni, gauze, zvipfeko zvinoraswa, mabhandeji, machira ekupfeka, uye zvimwe zvinhu zvisina kurukwa zviri pakati pemashandisirwo akanaka eshinda dzechisikigo. Mukugadzirwa kwekotoni, nzira dzekubatanidza dzakaita sehydroenanglement yezvigadzirwa zvinonyura zvakanyanya, kupisa kusungirirwa kwemisanganiswa ye polyolefin nekotoni, uye resin bonding (ye substrates) inogona kushandiswa.Technology ye synthetic fibers: Synthetic fibers inowanzosanganiswa ne rayon kana donje. Chero nzira yakakodzera yekubatanidza inogona kushandiswa kusvuta iwo. Meltblown synthetic fibers ndeimwe sarudzo. Meltblown fiber webs inofarirwa maapplication akaita seasina kurukwa masks ekuvhiya nekuda kwediki dhayamita yefiber uye yakanyanya kusefa. Chero nzira inogona kunyatso batanidza synthetic fibers, asi zvakanyanya zvinoenderana nekuti ichashandiswa sei pakupedzisira.

Post-processing: Medical nonwovens anofanirwa kupihwa kupera kwakakodzera kushandiswa kwakarongwa. Mask yekuvhiya isiri yakarukwa inogona kuve neakasiyana ekupedzisa maajenti, akadai seanodzinga mvura, zvinyoro-nyoro, zvinodzoreredza murazvo, antibacterial finishes, uye ivhu rinoburitsa maajenti. Mukupedzisa, zvigadzirwa zvisiri-zvakarukwa zvakazadza zvizere musika wemachira wekurapa nhasi. Machira asina kurukwa 'akasarudzika hunhu uye nyore kugadziridza zvaita kuti zvive zvakakosha muindasitiri ino. Nekuda kwekukurumidza kukura kwemaguta uye nekumuka kwevadiki, vanhu vane hanya nehutano, kudiwa kwezvokurapa zvisina kuruka kwakawedzera zvakanyanya munyika dzichiri kusimukira muAsia, Africa, neSouth America. Zvinotarisirwa kuti nonwovens acharamba achidiwa zvakanyanya muindasitiri yekurapa.
