Ayilukwanga ephuphumayo inyibilikisiweinkqubo: ukondla nge-polymer - ukukhupha okunyibilikisiweyo - ukwakheka kwefayibha - ukupholisa - kwinethiwekhi - ukuqinisa ngelaphu.
Uphuhliso lwetekhnoloji ye-melt-Jet nonwovens -- Itekhnoloji ye-melt-jet enamacandelo amabini
Ukususela kwinkulungwane yama-21, uphuhliso lwetekhnoloji ye-melt-jet nonwovens ehlabathini luye lwaphucuka ngokukhawuleza.
Isiseko sengxowa:
Ingenza izinto ezingezizo ezolukiweyo zivakale zithambile, zingenziwa zibe ziimveliso eziqinileyo, ezingaqhelekanga, ezinemilo ekhethekileyo. Ngokubanzi, umbindi wenziwe ngezinto ezingabizi kakhulu, kwaye i-polymer ebiza kakhulu eneempawu ezikhethekileyo okanye ezifunekayo ngumaleko wangaphandle, njenge-polypropylene core kunye ne-nylon outer layer ukwenza i-fiber ibe yi-hygroscopic. Umbindi yi-polypropylene, kwaye ulusu lwangaphandle lunamathela kwi-polyethylene esezantsi okanye i-modified polypropylene, i-modified polyester, njl. Kwi-carbon black conductive fiber, umbindi we-conductive ugqunywe kuyo.
Uhlobo lokudibana:
Ii-Nonwovens ezine-elasticity entle zihlala zenziwe ngee-polymers ezimbini ezahlukeneyo okanye i-polymer efanayo ene-viscosities ezahlukeneyo zibe zii-fibers ezimbini ezihambelanayo. Ukuncipha kobushushu okwahlukeneyo kwee-polymers ezahlukeneyo kungasetyenziselwa ukwenza ii-fibers ezine-spirally crimped. Umzekelo, inkampani ye-3M iphuhlise ii-nonwovens ze-PET/PP ezine-melt-sprayed two-component fiber nonwovens. Ngenxa yokuncipha okwahlukeneyo, ii-nonwovens zenza i-spiral crimp, nto leyo eyenza ii-nonwovens zibe ne-elasticity egqwesileyo.
Uhlobo lwesiphelo sendlela:
Oku kukwimo ye-polymmer enamagqabi amathathu, uhlobo olunqamlezileyo kunye nohlobo lwesiphelo, olufana nolwe-antistatic, ukuhanjiswa komswakama, i-fiber eqhubayo inokuba phezulu kwi-polymer edibeneyo, kungekuphela nje ukuba iqhubayo, iqhubayo, i-antistatic, kwaye igcine ubungakanani be-polymer eqhubayo.
Uhlobo lweMicrodenier:
Imo yepetali yeorenji, icandelo lohlobo lwestrip strip lingasetyenziswa, likwanokuba yinxalenye yohlobo lwesiqithi saselwandle. Ukusebenzisa iipolymers ezimbini ezingahambelaniyo ukuxobula ukwenza inethiwekhi yefayibha egqwesileyo, okanye inethiwekhi ye-nanofiber, efana nefayibha ye-strip-type two-component fiber kaKimberly-Clark, yinethiwekhi yefayibha egqwesileyo ethatha ithuba lokuba ifayibha yezakhi ezimbini ezenziwe ngeepolymers ezimbini ezingahambelaniyo inokuxobula ngokupheleleyo ngaphantsi komzuzwana emanzini ashushu. Uhlobo lwesiqithi saselwandle luya kunyibilikisa ulwandle ukuze lufumane inethiwekhi entle yefayibha yesiqithi.
I-hybrid:
Yinethiwekhi yeefayibha enezinto ezahlukeneyo, imibala eyahlukeneyo, iifayibha ezahlukeneyo, iimilo ezahlukeneyo zecandelo elinqamlezileyo, kwaye nokuba nesiseko sesikhumba sixutywe neefayibha ezijikelezayo kunye neefayibha ezimbini, ukuze iifayibha zibe nazo zonke iintlobo zeempawu ezifunekayo. Olu hlobo lweefayibha ezimbini ezinyibilikayo okanye iifayibha ezixutyiweyo ezingasetyenziswanga zinokuphucula ngakumbi ipropati yokucoca yesixhobo sokucoca xa kuthelekiswa neemveliso zefayibha ezinyibilikayo, kwaye zenze isixhobo sokucoca sibe nepropati echasene ne-static, ukuqhuba kombane, ipropati ye-hygroscopic, ipropati ephuculweyo yesithintelo, njl. Okanye yenza i-fiber mesh bond, i-fluffy, i-air permeability iphucuke.
Ifayibha yeshotcrete enyibilikisiweyo enamacandelo amabini inokongeza ukungabikho kokusebenza kwepolymer enye, njengepolypropylene ingabizi kakhulu, kodwa kwizixhobo zonyango, ayixhathisi kwimitha, ngoko ke inokuba yipolypropylene njengesiseko, kumaleko wayo wangaphandle ukukhetha ipolymer efanelekileyo enganyangekiyo kwimitha egqunywe ngaphandle inokusombulula ingxaki yokumelana nemitha. Ke ngoko, imveliso inokuba nexabiso eliphantsi kwaye ihlangabezane neemfuno ezisebenzayo, ezifana nezitshintshi zobushushu kunye nokufuma kwinkqubo yokuphefumla kwicandelo lezonyango, ezinokubonelela ngobushushu bendalo kunye nokufuma okufanelekileyo. Inobunzima obulula, ilahlwa okanye kulula ukuyibulala iintsholongwane, ingabizi kakhulu, kodwa ikwanokudlala indima eyongezelelweyo yokususa isihluzi sokungcola. Inokwenziwa ngenethiwekhi yefiber yokunyibilikisa-i-spray enamacandelo amabini exutywe ngokulinganayo.
Ifayibha yesikhumba yohlobo lwe-core ezimbini iyasetyenziswa, i-core yi-polypropylene kwaye i-cortex yi-nylon. Iifayibha ze-two-component nazo zinokubunjwa ngecandelo elikhethekileyo, njengemilo yamagqabi amathathu okanye imilo yamagqabi amaninzi, ukuze indawo yazo engaphezulu ibe nkulu. Okwangoku, ii-polymers ezinokuphucula ukusebenza kokucoca zingasetyenziswa kumaleko womphezulu okanye kwinxalenye yencam yefayibha. I-alkene okanye i-polyester fusible spray ene-two-component fiber mesh inokwenziwa ibe zizihluzi zolwelo kunye negesi. I-Melting spray ene-two-component fiber net ingasetyenziselwa incam yesihluzi secuba; Isiphumo sokufunxa esingundoqo sisetyenziselwa ukwenza i-inki suction core yodidi oluphezulu. Intonga yokufunxa engundoqo yokugcina ulwelo kunye nokufakwa, njl.
Uphuhliso lwetekhnoloji ye-melt blown nonwovens -- i-melt blown nanofibers
Ukuze kwenziwe ii-nanofibers, imingxunya ye-spinneret mincinci kakhulu kuneyo ifumaneka kwizixhobo ze-melt injection eziqhelekileyo. I-NTI inokuba ncinci njenge-0.0635 mm (oko kukuthi, ii-63.5 microns) okanye encinci njenge-0.0025 ft. Iiphaneli ze-modular spinneret zinokudityaniswa zibe nobubanzi obungaphezulu kwe-3 m. Ububanzi be-metal spray fiber spray spun ke ngoko bumalunga nee-nanometers ezingama-500. Ii-single fibers ezilungileyo zingafikelela kwii-nanometers ezingama-200 ububanzi.
Ekubeni izixhobo zokunyibilikisa nokutshiza ze-nanofibers ezijikelezayo zinemingxuma emincinci ye-orifical, ukuba akukho manyathelo athathwayo, imveliso iya kuncipha kakhulu. Ke ngoko, i-NTI isebenzisa indlela yokwandisa inani lemingxuma ye-orifical, kwaye ipleyiti nganye ye-spinneret inemigca emi-3 nangaphezulu yemingxuma ye-orifical. Ngokudibanisa inani lezinto zeyunithi (kuxhomekeke kububanzi), isivuno ngexesha lokujikeleza sinokunyuswa kakhulu. Imeko yokwenyani kukuba xa kusetyenziswa imingxuma engama-63.5 micron, inani lemingxuma kumqolo omnye we-spinnerets ngemitha yi-2880. Ukuba kusetyenziswa imigca emithathu, inani lemingxuma kumqolo omnye we-spinnerets ngemitha lingafikelela kwi-8640, ukuze imveliso ifane neye-spinning eqhelekileyo ye-shotcrete fiber.
Ngenxa yokuba ii-spinnerets ezincinci ezinemingxuma ephezulu zibiza kakhulu kwaye zinoqhekeko (ziqhekeka phantsi koxinzelelo oluphezulu), iinkampani ziye zaphuhlisa iindlela ezintsha zokubopha ukuphucula ukuqina kwee-spinnerets nokuthintela ukuvuza phantsi koxinzelelo oluphezulu.
Ifayibha etshiziweyo ene-nanometer ingasetyenziswa njengesixhobo sokucoca, nto leyo enokuphucula ukusebenza kakuhle kokuhluza. Kukwakho nedatha ebonisa ukuba ngenxa yokuba ifayibha kwi-nanometer melt-jet nonwovens incinci, ilaphu le-melt-jet lingadityaniswa nelaphu elinobunzima obuphantsi kwegram, elisenokumelana noxinzelelo olufanayo lwentloko yamanzi, kwaye iimveliso zeSMS ezenziwe ngalo zinokunciphisa umlinganiselo wefayibha ye-melt-jet.
Singabantuilaphu elingalukwanga elinyibilikisiweyo lemaski yobusoifektri, wamkelekile ukuba uqhagamshelane nathi ~
