Abstract

Fremgangsmåte til forening av vevnader.

Description

Oppfinnelsen vedrører en fremgangsmåte til å for-
ene vevnader, idet den dannede forbindelse er -motstandsdyktig overfor høye temperaturer og ikke er tykkere enn to ganger tekstilets tykkelse.
Det er kjent at tekstiler i vevet form kan forenes
ved stifting. En ulempe for mange anvendelser av denne metode for forbindelse er at forbindelsen er mange ganger tykkere enn tekstilet. Dette gir grunn til -dannelse av bulker under oppvik-ling av tekstilvevnaden til ruller.
Ifølge en annen kjent fremgangsmåte blir endene av tekstilet høy-frekvens-sveiset ved hjelp av en film for å unngå utbulning. I denne fremgangsmåte må filmen som benyttes for sveising ha en så høy dielektrisk tapsfaktor som mulig og et meget lavt mykningspunkt, således at den smelter under sveise-operasjonen og forbinder tekstilets ender. Ulempen ved denne fremgangsmåte ligger i den-meget dyre sveiseapparatur. ■ Videre er sveisesømmen ofte utilstrekkelig temperaturbestandig og ten-derer til å gå opp under etterfølgende belegning av tekstilet .
med et plastmateriale. Det er nå funnet at disse ulemper kan unngås ved å bruke fremgangsmåten ifølge oppfinnelsen.
Fra britisk patent nr. 908.516 er det kjent å an-vende klebefolier til fremstilling av forbindelser mellom poly-karbonatfilmer og celluloseesterfilmer og som på grunn av deres frie isocyanatgrupper og hydroksygrupper kan reagere med de to folietyper.
Oppfinnelsen vedrører en fremgangsmåte til å for-
ene stykker av vevnad, ved at en film plasseres mellom overlappende eller mot hverandre støtende ender av vevnaden som er impregnert med metylenklorid som oppløsningsmiddel for filmen og endene av vevnaden forenes ved etterfølgende påføring av trykk, idet fremgangsmåten er karakterisert ved at det som film
anvendes en høytemperaturmotstandsdyktig polyhydantoinfilm av 20 - 100/U tykkelse.
Polyhydantoinfilmer som er motstandsdyktige over-fo]r temperaturer opp1 til 260°C er spesielt egnet.
Ved fremgangsmåten ifølge oppfinnelsen anvendes altså en polyhydantoinfblie til sammenbinding av vevnader, idet polyhydantoinfolien i og for seg ikke har noen klebekraft og heller ingen reaktive grupper som kan reagere med vevnadene.
Det er- derfor overraskende at man ved anvendelse av disse poly-hydantoinf ilmer ved enkle forholdsregler får forbindelser av vevnader som ikke bare har en utmerket fasthet, men også er høytemperaturbestandige og har en utmerket kjemikalieresistens. Man-ville ha ventet da det ikke finner sted noen kjemisk reak-sjon mellom delene som skal forbindes og folien at den korte svelletid av polyhydantoinfolien ved hjelp av oppløshingsmidlet som befinner seg i enden av vevnadsbahen og den etterfølgende korte sammehpresning ikke skulle være tilstrekkelig til å gi faste forbindelser med fremragende temperaturfasthet.
Trykket som påføres under pressingen er vanligvis fra 5 til 55 kp/cm 2. Pressingen utføres vanligvis ved værelses-temperatur. Økningr av presstemperatureh til oppløsningsmidlets kokepunkt kan øke styrken av forbindelsen og redusere den nød-vendige presstid, som normalt varer fra 1 sekund til 1 minutt ti-1 kortere pressperioder.
Ved hjelp av fremgangsmåten ifølge oppfinnelsen kan tekstiler av naturlig og syntetisk opprinnelse, f.eks. bomulls-tekstiler eller tekstiler av polyestere, polyamider, polyuretan-er eller glass forenes meget hurtig og godt. Det kan dannes endeløse vevnader av tekstil, og det er ikke noen fare for at tekstilvevnadene blir løsnet fra hverandre under etterfølgende belegning med et plastmateriale.
Eksempel 1.
For en ende-mot-ende-forbindelse av vevnader av bomullstekstil er endene av vevnaden som skal forbindes impregnert med metylenklorid og plassert ende-mot-ende. En omtrent 2 cm bred strimmel av en lOO^u tykk polyhydantoinfilm plasseres på den ene overflate av endene av tekstilet. Forbindelsen presses for omtrent 10 sekunder under et trykk på omtrent 20 kg/cm og ved en presstemperatur på rundt 40°C. Styrken av forbindelsen er generelt større enn for tekstilet og derfor kan det ikke angis noe tall. Forbindelsen er motstandsdyktig overfor temperaturer opp til 260°C, upåvirket ved kokning i 10$-rig natriumhydroksyd-oppløsning og kokning i en oppløsning av hydrogenperoksyd og_ ødelegges ikke når tekstilet belegges med en smelte av plastifisert PVC ved 230 - 250°C.
Eksempel 2.
En 20_ mm bred strimmel av lOOyU tykk polyhydantoin-f.ilm plasseres på begge overflater av mot hverandre liggende ender av en glassfilamenttekstil i vevet form, idet tekstilets ender er fuktet med metylenklorid. Forbindelsen presses i 5
til 10 sekunder under, et press på 20 kg/cm 2 ved en presstemperatur på rundt 40°C. Styrken av forbindelsen er generelt større enn for tekstilet og derfor kan det ikke angis noe tall. Forbindelsen er motstandsdyktig overfor temperaturer opp til 260°C, upåvirket ved kokning i 10%- lg natriumhydroksydoppløsning og kokning i en oppløsning av hydrogenperoksyd og ødelegges ikke når tekstilet belegges med en smelte av plastifisert PVC ved 230 - 250°C. E ksempel 3-
En strimmel av ikke-orientert amorf polyhydantoin-film med en tykkelse på omtrent 40^u innføres mellom overlappende ender av et bomullstekstil hvis ender har blitt behandlet med metylenklorid. Endene av tekstilvevnaden presses på hverandre i ca. 10 sekunder ved et trykk på rundt 20 kp/cm p og en presstemperatur på rundt 40°C. Styrken av forbindelsen er større enn styrken av vevnaden, selv når styrkene sammenlignes ved forhøyet temperatur. Følgelig er det ikke mulig å angi noen tall for styrken av forbindelsen. Forbindelsen er motstandsdyktig overfor temperaturer opp til.260°C og er upåvirket ved kok-
ing i 10%-ig natriumhydroksydoppløsning og koking i en oppløs-ning av hydrogenperoksyd, og ødelegges ikke ved belegning av tekstilet med en smelte av plastifisert PVC.
Eksempel 4.
En strimmel av ikke-orientert amorf polyhydantoin støpefilm plasseres mellom overlappende ender av et glassfilamenttekstil i vevet form, idet disse ender er fuktet med metylenklorid. Vevnadens ender presses på hverandre i 10 sekunder ved et trykk på 12 kp/cm 2 og en presstemperatur på rundt <i>l0°C. Styrken av forbindelsen er større enn styrken av vevnaden og følgelig er det ikke mulig å angi et tall for styrken av forbindelsen. Forbindelsen er motstandsdyktig mot temperaturer opp til 260°C.
