Description
Fremgangsmåte til fremstilling av kunstlær med viltlæraktig karakter. Process for the production of artificial leather with a game leather-like character.
• Den foreliggende oppfinnelse går ut på • The present invention is based on
fremstilling av et kunstlær med viltlæraktig karakter, som egner seg som erstatningsstoff for alle anvendelsesformål, hvor ellers vanlig viltlær eller viltlærimitasjoner kommer på tale. Spesielt er kunstlæret fremstilt i hen-hold til oppfinnelsen på grunn av sin smidig-het, styrke, motstandevne mot kulde og sli-tasje samt mot alderen egnet til fremstilling av sko og bekledningsgjenstander av alle ar-ter av vesker, belter, foringslær o.s.v. Den viltlæraktige karakter fåes ved at et underlag, f. eks. vevet eller strikket stoff, papir, fiber-matte e. 1., som allerede er forsynt med et mer eller mindre sterkt gelatinert smidig polyvi-nylkloridlag i størrelsesorden mellom 100 og 800 g/m<2>, bestrykes med en passende farget polyvinylkloridpasta i en mengde av 50 til 100 g/m<2>. På dette fremdeles myke, nesten flytende påstrøk av polyvinylkloridpasta blir det ved hjelp av en passende påstøvnings-anordning påstøvet pulverformet ammoniumkarbonat eller ammoniumbikarbonat. Deretter blir den således preparerte kunstlærbane ført gjennom en fra 140 til 170° opphetet gelatineringskanal. Ammoniumsaltet forgas-ses da under dannelse av vanndamp, kullsyre og ammoniakk, og det blir tilbake en finporet overflate, som tilsvarer den ønskede viltlæraktige karakter. production of an artificial leather with a game leather-like character, which is suitable as a replacement material for all purposes of use, where ordinary game leather or game leather imitations come into question. In particular, the artificial leather produced in accordance with the invention is, due to its flexibility, strength, resistance to cold and wear and tear as well as to age, suitable for the production of shoes and clothing items of all types of bags, belts, lining leather, etc. The game leather-like character is obtained by a substrate, e.g. woven or knitted fabric, paper, fiber mat etc. 1., which has already been provided with a more or less strongly gelatinized flexible polyvinyl chloride layer in the order of magnitude between 100 and 800 g/m<2>, is coated with a suitable colored polyvinyl chloride paste in an amount of 50 to 100 g/m<2>. Powdered ammonium carbonate or ammonium bicarbonate is dusted onto this still soft, almost liquid coat of polyvinyl chloride paste using a suitable dusting device. Next, the thus prepared artificial leather web is passed through a gelatinization channel heated from 140 to 170°. The ammonium salt is then gasified with the formation of water vapour, carbonic acid and ammonia, and a fine-pored surface is left, which corresponds to the desired game leather-like character.
Eksempel: Example:
Et halvfabrikat av kunstlær, bestående av en bomullsvev med vekt ca. 140 g/m<2> i Nesselbinding og et mykt, smidig lag av poly vinylklorid i en mengde av 300 g/m<2>, blir på vanlig måte forsynt med et belegg av polyvinylkloridpasta av følgende sammensetning: 45,0 % polyvinylklorid 29,0 % dioktylftalat A semi-finished product made of artificial leather, consisting of a cotton fabric weighing approx. 140 g/m<2> in Nessel binding and a soft, flexible layer of poly vinyl chloride in an amount of 300 g/m<2>, is normally provided with a coating of polyvinyl chloride paste of the following composition: 45.0% polyvinyl chloride 29.0% dioctyl phthalate
5,3 % dibutylftalat 5.3% dibutyl phthalate
19,9 % pigmentfargestoff 19.9% pigment dye
0,8 % blystearat. 0.8% lead stearate.
Like bak avstrykerkniven blir det ved hjelp av en mekanisk påstøvningsinnretning påstøvet fint pulverisert ammoniumkarbonat ved temperaturer på 120 til 160° forgassbart stoff på denne kunstlærbane, og dette i en slik mengde at overflaten nettopp blir fullstendig dekket med ammoniumkarbonatet og på grunn av krystallene får et hvitaktig ut-seende. Den således preparerte kunstlærbane blir deretter straks ført inn i gelatinerings-kanalen, som er opphetet til ca. 160°, og for-blir i denne mellom 5 til 10 minutter inntil alt karbonatet er fullstendig forgasset. Den avkjølte vare kan eventuelt, hvis behøves, slipes lett. Just behind the squeegee, with the help of a mechanical dusting device, finely powdered ammonium carbonate is dusted at temperatures of 120 to 160° on this artificial leather track, and this in such a quantity that the surface is just completely covered with the ammonium carbonate and, due to the crystals, acquires a whitish look. The thus prepared synthetic leather track is then immediately introduced into the gelatinization channel, which is heated to approx. 160°, and remains in this between 5 and 10 minutes until all the carbonate is completely gasified. The cooled product can optionally, if necessary, be sanded lightly.
