Zvinhu Zvikuru Kuseri Kwakasimba uye Kugara Kwakasimba Nonwoven Fabric
- Sarudza chakanaka synthetic fiber, se polypropylene kana polyester, kuwedzera kusimba uye kusimba kwemachira asina kurukwa kune akasiyana maapplication.
- Shandisa nzira dzekubatanidza dzinoshanda, sekubaya tsono kana kupisa kubatanidza, kuvandudza kuramba kwejira kubvaruka uye delamination.
- Nyorera marapirwo ane hunyanzvi kuti uwedzere zvivakwa zvakaita sekudzivirira mvura uye kuramba abrasion, kuve nechokwadi chekuti machira asina kuruka anoita zvakanaka munzvimbo dzinodiwa.
Kusarudzwa kweFiber kune Yakasimba Nonwoven Fabric
Synthetic Fiber Types
Vagadziri vanovimba nesimbi dzekugadzira kugadzira jira rakasimba risingarukwa yekuda kunyorera. Polypropylene, polyester, uye polyamide fibers inotonga indasitiri nekuda kwesimba ravo remuchina uye kuramba kushushikana kwezvakatipoteredza. Aya mafiber anopa kuenderana kwemhando uye kuita, zvichiita kuti dzive dzakakodzera kurapwa, industrial, uye mutengi zvigadzirwa.
Synthetic fibers ipai musana wejira rakasimba risingarukwa. Zvivakwa zvavo zveenjiniya zvinobvumira kugadzirisa musimba, flexibility, uye makemikari kuramba.
Tafura inotevera inotaridza iyo inonyanya kushandiswa fiber mhando uye yakajairika maapplication:
| Fiber Type | Applications |
|---|---|
| Polypropylene fiber | Geosynthetics, makapeti, zvipfeko zvekuvhiya, masks, manapukeni, zvinhu zvinotora mafuta, filters, etc. |
| Polyester | Insulation zvinhu, thermal insulation flocs, wallcloth, zvipfeko zvekupfeka, zvinhu zvisingapindi mvura, etc. |
| Polyamide fiber | Kupfeka nguo, bepa gumbeze, kapeti, synthetic leather base jira, kukwenenzvera zvinhu, etc. |
| Polyvinyl doro fiber | Composite zvinhu zvine polypropylene, embroidery base jira, zvinhu zvinoraswa. |
| Polyacrylonitrile fiber | Dziya-up flocs, artificial fur, magumbeze, etc. |
Polypropylene uye polyester inomira pachena nekuda kwekusiyana-siyana kwavo uye kusimba. Polypropylene inopa yakanakisa hydrophobicity, nepo polyester inokunda mumichina zvivakwa uye nyore kubereka. Faibha idzi dzinotsigira kugadzirwa kwejira rakasimba risingarukwe rinosangana nezvinodiwa nemaindasitiri akasiyana.
Fiber Simba uye Zvivakwa
Hunhu hwemuviri hwemafayibha ekugadzira hunoona kusimba uye kusimba kwezvinhu zvisina kuruka. Fiber dispersion, bonding techniques, uye inherent faibha maitiro ese anobatsira mukuita kwejira rakasimba risiri rakarukwa.
| Mechanism/Property | Tsanangudzo |
|---|---|

Polyester uye polypropylene fibers inobatsira mukugarisa kwejira rakasimba risiri rakarukwa. Kugara kwavo kunoderedza kudiwa kwekugara uchitsiviwa, uye kudzokorora kwavo kunotsigira zvinangwa zvezvakatipoteredza. Vagadziri vanosarudza aya mafibhi kuti aenzanise mashandiro, mutengo-kubudirira, uye kusimba mune nonwoven zvigadzirwa.
Zano: Kusarudza iyo chaiyo fiber mhando inovimbisa kuti yakasimba nonwoven jira rinosangana nezvinodiwa zvega rega rega, kubva kumasikisi ekurapa kusvika kukudzivirira kwekunze.
Bonding uye Kuvaka Techniques
Mechanical uye Thermal Bonding
Mechanical uye thermal bonding inoita basa repakati mukugadzirwa kwesimba micheka isina kurukwa. Kubaya tsono kunomira pachena seyekutanga mechanical process. Iyi nzira inoshandisa tsono dzine minzwa kupinza shinda, kugadzira chimiro chakaomeswa uye chakabatana. Maitiro acho haavimbi nekupisa kana makemikari. Pane kudaro, inoshandisa simba kugadzira machira ane kukwirira kupikisa delamination uye kusimba kwakanyanya. Needle-punched nonwoven upholstery jira rinowanzo onekwa mukugadzira mota, geotextiles, uye zvifukidzo zvepasi.
Mechanical bonding, muchimiro chayo chakatanhamara sokubaya tsono, inzira yehutsinye hunoyevedza. Inoumba kuvimbika kwejira kwete kuburikidza nekupisa kana makemikari, asi kuburikidza nekupinda zvine simba uye kwakadzokororwa kwetsono dzine minzwa. Iyi nzira inogadzira dense, bulky, uye machira akasimba akasarudzika ayo ari musana weanoda maindasitiri segeotextiles, kugadzira motokari, uye zvifukidzo zvepasi. Musimboti wekubaya tsono unosanganisira dandemutande riri kupfuudzwa kuburikidza ne‘shinda yetsono’ uko tsono dzehunyanzvi dzinopinda pawebhu, kubatanidza fiber uye kugadzira matatu-dimensional, misa yakabatana zvakanyanya. Iyi Z-direction fibre orientation ndiyo sosi yesimba remachira, resilience, uye kuramba delamination.
Mamwe ma mechanic process anosanganisira frictional bonding uye stitch bonding. Frictional bonding inotsamira pakukweshana kwepamusoro kwefaibha kugadzira jira risingarukwa reupholstery riine kukwirira kukuru kusapfeka uye kubvaruka.. Stitch bonding inoshandisa stitches kubata fiber pamwechete, kuwedzera kusanzwa kwemisodzi uye kuramba mapiritsi. Idzi nzira dzinowedzera kusimba kwese uye kusimba kwemhando dzakasiyana dzemachira asina kuruka.
Thermal bonding inoshandisa kupisa uye kumanikidza kusanganisa fiber. Iyo nzira inotanga nekuisa pasi fiber munzvimbo inodzorwa. Adhesive inoshandiswa, zvino kudziyisa uye kudzvanywa kugadzira zvisungo zvakasimba. Iyi nzira inogadzira zvinhu zvisina kurukwa zvine hunyanzvi hwekuramba kubvaruka, flexibility, uye kusimba. Thermal bonding inomira kunze kwekudhura kwayo-kushanda uye nemazvo. Inochengetedza yunifomu ukobvu uye inopindirana magadzirirwo, ayo akakosha kune emhando yepamusoro machira asina kuruka. Kuenzaniswa nemakemikari bonding, thermal bonding inoda simba shoma uye inoderedza mari yekugadzira. Inodzivisawo kushandiswa kwemakemikari ane utsinye, zvichiita kuti ive yakakodzera kune zvekurapa uye kusefa zvikumbiro.
Thermal bonding inowedzera kusimba uye chimiro chekuvimbika kwemachira asina kuruka. Iyi nzira inovandudza zvose simba uye kushanduka, izvo zvakakosha kune mafirita masisitimu uye zvinoraswa zvekurapa. Hydroentangling, imwe nzira, inoshandisa high-pressure water jets kupinza mafiibha, zvichiita kuti zvive zvinyoro uye zvinonwisa nonwovens. Aya machira anoratidza kupikisa kwakanyanya kune abrasion uye kuchengetedza kuita kwavo munzvimbo dzinoda.
Fabric Density uye Layering
Density yemucheka uye kuiswa zvakanyanya kunokanganisa kusimba uye kuramba kwezvinhu zvisina kuruka. Heavyweight nonwoven geotextiles, nehuremu hukuru kupfuura 8 oz./sq yd., kupa kwakawedzerwa kusimba uye kugadzikana. Aya machira akanakira mapurojekiti akaita semadziro ekuchengetedza uye ebankment, uko kupikisa kwakanyanya kushushikana uye zvakatipoteredza zvinhu zvinodiwa.
Kuwedzera huwandu hwemachira mujira risingarukwa rinowedzera kusada kubvaruka uye kusimba kwese. Micheka yakasanganiswa, iyo inosanganisa akawanda layers, kuratidza simba rekubvarura rakakwirira kudarika zvivakwa zve-single-ply. Nheyo imwe neimwe inogona kushanda basa chairo, zvakadai sekupa kusada kupfeka, simba rakakwirira, kana kunyaradza. Multi-layer dhizaini inobvumira kushushikana kugovana, iyo inoderedza kumanikidzwa kwakadzika uye inodzivirira kubvarura. Kana imwe layer ikakuvara, zvikamu zvakasara zvinochengetedza kuvimbika kwejira, kuwedzera hupenyu hwayo hwesevhisi.
- Machira eComposite anoratidza yakakwira simba rekubvarura zvichienzaniswa nezvimwe zvimiro zveply.
- Kuwedzera huwandu hwemachira machira anowirirana nesimba guru rekubvarura.
- Kuwedzerwa simba rekubvarura kunoratidza kuvandudzwa kwekuramba kubvarura.
- Kuisa zvidimbu zvakasiyana-siyana zvefiber zvinowedzera simba uye kusimba.
- Nheyo imwe neimwe inogona kugadzirwa kune mamwe mabasa, zvakadai sokupfeka kuramba, simba rakakwirira, uye kunyaradza.
- Multi-layer dhizaini inobvumira kugovana kunetseka, kuderedza concentrated pressure uye kudzivirira kubvarura.
- Kana imwe layer yakuvadzwa, mamwe matinji anogona kuchengetedza kuperera, kuwedzera hupenyu hwebasa rejira.
Kuvakwa kwepamusoro-density zvakare kunonatsiridza kuramba kune abrasion, pilling, uye kubvarura. Iyi nzira yakajairika mune nonwoven upholstery jira uye maindasitiri application, uko kushanda kwenguva refu kunokosha. Iyo nzira yekuisa uye kuwedzera density inovimbisa kuti jira rinogona kutsungirira kushandiswa kwakadzokororwa uye mamiriro akaomarara.
