Senhengo yeboka reDörken, Multitexx inokwevera paanenge makore makumi maviri echiitiko mukugadzira spunbond.
Kuzadzisa kudiwa kweakareruka, akasimba-akasimba spunbond nonwovens, Multitexx, kambani nyowani iri muHerdecke, Germany, inopa spunbond nonwovens akagadzirwa kubva emhando yepamusoro polyester (PET) uye polypropylene (PP) yekuda maapplication.
Senhengo yeboka repasi rose reDörken, Multitexx inokwevera paanenge makore makumi maviri echiitiko mukugadzira spunbond. Iyo kambani yevabereki yakavambwa makore zana nemakumi maviri neshanu apfuura uye yakatanga kugadzira nekugadzira denga rakadzika pasi kumashure kuma1960s. Muna 2001, Dörken akawana mutsara wekugadzira weReicofil spunbond ndokutanga kugadzira zvayo spunbond zvinhu zvemusika wakaumbwa wekuvaka laminate.
"Mushure memakore e15, kukurumidza kukura kwebhizimisi kwakakonzera kudiwa kwekutenga mutsara wechipiri wepamusoro weReicofil," inotsanangura kambani. "Izvi zvakagadzirisa dambudziko rekugona kuDörken uye zvakapawo kukurudzira kwekugadzira Multitexx." Kubva muna Ndira 2015, kambani nyowani yanga ichitengesa zvemhando yepamusoro spunbond zvinhu zvakagadzirwa kubva thermally calendered polyester kana polypropylene.
Iyo Dörken Boka mitsetse miviri yeReicofil inogona kuchinjanisa kushandiswa kwemapolima maviri uye kugadzira spunbond kubva kune chero chinhu chine density yakaderera uye yakanyanya kuenderana. Iyo polymer inopinda mumutsara wekugadzira kuburikidza nemitsara yakaparadzana yekudyisa yakagadziridzwa kune yakakodzera mbishi zvinhu. Sezvo polyester particles agglomerate pa 80 ° C, vanofanira kutanga crystallized uye kuomeswa asati extrusion. Inobva yadyiswa mukamuri yedosing, iyo inodyisa extruder. Iyo extrusion uye kunyunguduka tembiricha yepolyester yakanyanya kukwirira kupfuura iyo yepolypropylene. Iyo polymer yakanyungudutswa (PET kana PP) inozopombwa mupombi inotenderera.
Iyo yakanyungudutswa inodyiswa mufa uye yakagovaniswa zvakanaka pamusoro pehupamhi hwese mutsara wekugadzira uchishandisa imwe-chidimbu chinofa. Kutenda kune yayo-chidimbu dhizaini (yakagadzirirwa mutsara wekugadzira unoshanda wakafara we3.2 metres), mold inodzivirira hurema hunogona kuumba muchinhu chisina kuruka nekuda kwewelds yakagadzirwa neakawanda-chidimbu molds. Nekudaro, iyo Reicofil yakatevedzana spinnerets inoburitsa monofilament filaments ine imwechete filament fineness inosvika 2.5 dtex. Dzinobva dzatambanudzwa kuita tambo dzisingaperi kuburikidza nema diffuser marefu akazadzwa nemhepo patembiricha inodzorwa uye kumhanya kwakanyanya kwemhepo.
Chinhu chakasiyana cheizvi zvigadzirwa zve spunbond ndeye oval-shaped imprint yakagadzirwa nehot-calender embossing rollers. Circular embossing yakagadzirirwa kuwedzera kusimba kwesimba rezvigadzirwa zvisina kuruka. Mushure mezvo, jira remhando yepamusoro spunbond risingarukwa rinopfuura nematanho akadai sekutonhodza mutsara, kuongorora kukanganisa, kutsemura, kuchinjika-kucheka uye kumonereka, uye pakupedzisira inosvika pakutumirwa.
Multitexx inopa polyester spunbond zvinhu zvine filament fineness inosvika 2.5 dtex uye density kubva pa15 kusvika 150 g/m². Pamusoro pekufananidzwa kwepamusoro, hunhu hwechigadzirwa hunonzi hunosanganisira kusimba kwesimba, kupisa kupisa uye kuderera kwakanyanya. Kune spunbond polypropylene zvinhu, nonwovens akagadzirwa kubva pure polypropylene warn ane density kubva pa17 kusvika 100 g/m² anowanikwa.
Mutengi mukuru we Multitexx spunbond machira ndiyo indasitiri yemotokari. Muindasitiri yemotokari, akati wandei akasiyana e spunbond anoshandiswa, semuenzaniso, sevhavha inonzwika, magetsi ekudzivirira kana kusefa chinhu. Kambani iyi inoti kuenzana kwavo kwakanyanya kunoita kuti vakwanise kusefa zvinwiwa, zvinobudirira kushandiswa mumhando dzakasiyana dzemashandisirwo kubva pakucheka mvura yekusefa kusvika pakusefa doro.
Mitsetse miviri yespunbond inoshanda nguva yese yewachi uye ine hunyanzvi hwepamusoro. Zvinoenderana nekambani, GKD's CONDUCTIVE 7701 loop yakafara mamita 3.8 uye inoda kusvika 33 metres kureba, inosangana nezviyero zvakawanda uye inokodzera kumanikidzwa kwenguva refu. Iyo tepi chimiro dhizaini inosimudzira kufema kwakanaka uye kufanana kwema mesh. Zvinonzi zvakare kureruka kwekuchenesa mabhandi eGKD kunovimbisa kushanda kwepamusoro.
"Panyaya yezvigadzirwa zvezvigadzirwa, mabhanhire eGKD pasina mubvunzo mabhanhire akanakisisa mumutsara wedu," anodaro Andreas Falkowski, Mutungamiri weChikwata cheSpunbond Line 1. Nokuda kwechinangwa ichi, takarayira rimwe bhanhire kubva kuGKD uye ikozvino tiri kugadzirira kugadzirwa. Panguva ino ichave iyo itsva CONDUCTIVE 7690 bhandi, iyo inoratidzira zvakanyanya coarser bhandi chimiro munzira yekufamba.
Iyi dhizaini inonzi inopa bhandi rekutakura rine yakakosha grip yakagadzirirwa kuvandudza traction munzvimbo yekuturika uye kuwedzera optimize yekuchenesa bhandi rekutakura. “Hatina kumbova nedambudziko rekutanga mushure mekuchinja mabhande, asi kushata kunofanira kuita kuti zvive nyore kubvisa madrip mumabhande,” anodaro Andreas Falkowski.
