Title (EN) INSPECTION LIQUID FOR INSPECTING WHETHER LEATHER HAS BEEN TREATED USING HEXAVALENT CHROMIUM REDUCING COMPOUND
(FR) LIQUIDE D’INSPECTION DESTINÉ À UNE INSPECTION POUR DISTINGUER UN CUIR TRAITÉ PAR UN COMPOSÉ DE RÉDUCTION DE CHROME HEXAVALENT D’UN AUTRE
(JA) 6価クロム還元化合物で処理された革であるかを検査するための検査液
Abstract:
(EN) [Problem] To provide an inspection liquid and inspection method for inspecting whether leather is leather that has been treated using a hexavalent chromium reducing compound. In other words, to provide a hexavalent chromium reduceability inspection liquid and inspection method for inspecting whether leather has been treated in such a manner that trivalent chromium contained in leather that has been subjected to chromium tanning does not change to hexavalent chromium. [Solution] The inspection liquid of the present invention is an inspection liquid for inspecting whether leather has been treated by a hexavalent chromium reducing compound that can reduce hexavalent chromium into trivalent chromium, and is characterized by containing an iron-containing compound that is discoloured by reaction with said hexavalent chromium reducing compound, and a water-based solvent.
(FR) L’invention fournit un procédé d’inspection, et un liquide d’inspection destiné à une inspection des cuirs pour distinguer un cuir traité par un composé de réduction de chrome hexavalent d’un autre. Plus précisément, l’invention fournit un procédé d’inspection et un liquide d’inspection de propriétés de réduction de chrome hexavalent destiné à une inspection pour savoir si un traitement a été effectué afin de ne pas modifier un chrome trivalent compris dans les cuirs après tannage au chrome hexavalent. Le liquide d’inspection destiné à une inspection pour distinguer un cuir traité par un composé de réduction de chrome hexavalent d’un autre de l’invention permet de soumettre un cuir à une réduction de chrome hexavalent en chrome trivalent, et est caractéristique en ce qu’il contient un composé à teneur en fer permettant un changement de couleur par réaction avec un composé de réduction de chrome hexavalent, et un solvant aqueux.
(JA) [課題]革が、6価クロム還元化合物で処理された革であるかを検査するための検査液および検査方法を提供すること。いいかえると、クロムなめし後の革に含有される3価クロムが6価に変化しないように処理が行われているかを検出するための6価クロム還元性検査液および検査方法を提供すること。 [解決手段]本発明の検査液は、革が、6価のクロムを3価のクロムに還元し得る6価クロム還元化合物で処理された革であるかを検査するための検査液であって、該6価クロム還元化合物と反応して発色し得る鉄含有化合物と、水系溶媒とを含むことを特徴とする。
