Abstract
Werkwijze voor het lichtdoorlatend maken van leder, omvat- tende het tijdens en/of na nalooiing van het leder op of in het leder aanbrengen van één of meer soorten was uit de groep: paraffine, bijenwas, candelillawas, carnaubawas, of een mengsel daarvan. De aangebrachte hoeveelheid was komt overeen met ten minste 75 gram, bij voorkeur ten minste 95 gram, was per 1 m2 leder met een dikte van 1 mm. Het van was voorziene leder wordt in een droogtunnel blootgesteld aan een temperatuur van ten minste 75°C, bij voorkeur ten minste 85°C.Method for making leather translucent, comprising applying one or more types of wax from the group: paraffin, beeswax, candelilla wax, carnauba wax, or a mixture thereof, during and/or after tanning of the leather. The amount of wax applied corresponds to at least 75 grams, preferably at least 95 grams, of wax per 1 m 2 of leather with a thickness of 1 mm. The waxed leather is exposed in a drying tunnel to a temperature of at least 75°C, preferably at least 85°C.
Description
i Korte aanduiding: Werkwijze voor het lichtdoorlatend maken van lederi Short designation: Method for making leather translucent
BESCHRIJVING De uitvinding heeft betrekking op een werkwijze voor het lichtdoorlatend maken van leder. Voor algemene informatie over leder sn de looimethoden er” van kan worden verwezen naar bijvoorbeeld 13 https: //nl.qwe wiki/wiki/Leather, De onderhavige uitvinding beoogt te voorzien in een tot dusverre niet gebruikte werkwijze voor het lichtdoorlatend maken van leder, bijvoorbesld ten behoeve van lampen, wan- den, tafels, plafonds etc, Daartoe wordt voorzien in een werkwijze voor het lichtdocor- latend maken van leder, omvattends: ~ het voorzien in chroonvrij gelooid ("wel white") leder, 23 bij voorkeur niet of slechts licht op kleur geverfd in het val bijdens nalooiing; — het tijdens en/of na nalociing van het leder op of in het leder aanbrengen van één of meer soorten was uit de groep: paraffine, bijenwas, candelillawas, carnaubawas, of een mengsel daarvan, De aangebrachte hoeveelheid was komt overeen met ten minste 75 gram, bij voorkeur ten minste 95 gram, was per 1 mn le-DESCRIPTION The invention relates to a method for making leather translucent. For general information on leather and its tanning methods, reference may be made to e.g. 13 https://en.qwe wiki/wiki/Leather. The present invention aims to provide a hitherto unused method for rendering leather translucent, for example for lamps, walls, tables, ceilings, etc. To this end, a method is provided for making leather light-transmitting, comprising: ~ providing chrome-free tanned ("white") leather, 23 preferably not or only lightly dyed in the fall during final tanning; — applying one or more types of wax from the group: paraffin, beeswax, candelilla wax, carnauba wax, or a mixture thereof, or a mixture thereof, during and/or after re-lociation of the leather, The amount of wax applied corresponds to at least 75 grams, preferably at least 95 grams, wash per 1 mn leg-
der met een dikte van 1 mm, gemeten vóór droging van het geheel. De op een stuk leder aan te brengen hoeveelheid was kan dan aldus worden berekend: $ Hoeveelheid was (liter) = A x Oppervlak (mn) x Dikte {rm}. De factor A moet dan volgens de uitvinding gelijk zijn aan ten minste 75 {gram} / soortelijk gewicht {gram/liter} van de te gebruiken soort was.der with a thickness of 1 mm, measured before drying of the whole. The amount of wax to be applied to a piece of leather can then be calculated as follows: $ Amount of wax (litres) = A x Area (mn) x Thickness {rm}. According to the invention, the factor A must then be equal to at least 75 {gram} / specific weight {gram/litre} of the type of wax to be used.
Bijvoorbeeld is dan voor het lichtdoorlatend maken van sen stuk chroomvrij voorgelooid of gelooid leder van 2 nm’ met gen dikte van 1,5 mm met behulp van paraffine (s.g. 200 gr/liter} ten minste nodig: is (7% x 2 = 1,5) / 900 {gr/liter) = 0,25 liter paraffine, De was kan bijvoorbeeld in gesmolten toestand op het leder worden aangebracht of in bijvoorbeeld korrel- of vlokvomm, In dat laatste geval smelt de was dan bijvoorbeeld in de verwarde) droogtunnei.For example, to make a piece of chromium-free pre-tanned or tanned leather of 2 nm' with a thickness of 1.5 mm using paraffin (s.g. 200 gr/litre} .5) / 900 {gr/litre) = 0.25 liters of paraffin, The wax can be applied to the leather, for example, in a molten state or in, for example, grain or flake shapes, In the latter case, the wax will then melt, for example, in the tangled condition) drying tunnel.
Het van de benodigde hoeveelheid was voorziene leder wordt bij voorkeur in een droogtunnel blootgesteld aan een tem- peratuur van ten minste 75°C, bij voorkeur ten minste S85°0, Optioneel kan aan de was maximaal 25% olie worden Loege- voegd.The leather provided with the required amount of wax is preferably exposed in a drying tunnel to a temperature of at least 75°C, preferably at least 85°C. Optionally, a maximum of 25% oil can be added to the wax.
36 Aldus wordt door de onderhavige uitvinding voorzien in een tot dusverre niet gebruikte werkwijze voor het lichtdoorla- tend maken van leder.Thus, by the present invention there is provided a heretofore unused method for rendering leather translucent.
