Abstract:

(EN)The present invention relates to a method for producing a recycled leather sheet and, particularly, to a method for producing a recycled leather sheet from leather waste. The method for producing a recycled leather sheet by using leather fibers comprises the steps of: performing a pre-treatment process for neutralizing leather waste and attaching a fatliquoring agent thereto; separating leather fibers from the leather waste which has been subjected to the pre-treatment process; blending the separated leather fibers with fibers for improving the tensile strength of the separated leather fibers; and bonding the blended fibers to a base fabric to form a sheet. As described above, the method for producing a recycled leather sheet according to the present invention can be used to produce a recycled leather sheet through physical bonding without using an adhesive, thereby minimizing environmental pollution.
(FR)La présente invention concerne un procédé de production d'une feuille de cuir recyclé et, en particulier, un procédé de production d'une feuille de cuir recyclé à partir de déchets de cuir. Le procédé de production d'une feuille de cuir recyclé à l'aide de fibres de cuir comprend les étapes consistant à : effectuer un processus de prétraitement pour neutraliser les déchets de cuir et fixer une liqueur grasse sur ceux-ci ; séparer les fibres de cuir des déchets de cuir qui ont été soumis au traitement de prétraitement ; mélanger les fibres de cuir séparées avec des fibres afin d'améliorer la résistance à la traction des fibres de cuir séparées ; et lier les fibres mélangées à un tissu de base pour former une feuille. Comme décrit ci-dessus, le procédé de production d'une feuille de cuir recyclé selon la présente invention peut être utilisé pour produire une feuille de cuir recyclé par liaison physique sans utiliser d'adhésif, ce qui permet de réduire au minimum la pollution de l'environnement.
(KO)본 발명은 가죽시트의 제조 방법에 관한 것으로서, 특히, 가죽 폐기물로 제조된 재생 가죽시트의 제조방법에 관한 것이다. 가죽섬유를 이용한 재생 가죽시트의 제조 방법은 가죽 폐기물을 중성화하고 가지제를 부착하는 전처리공정을 수행하는 단계; 상기 전처리공정을 거친 가죽 폐기물에서 가죽섬유를 분리하는 단계; 상기 분리된 가죽섬유와 상기 분리된 가죽섬유의 인장강도 향상을 위한 섬유를 혼섬하는 단계; 및 상기 혼섬된 섬유를 바닥지 원단과 결합하여 시트를 형성하는 단계;를 포함하는 것을 특징으로 한다. 전술한 바와 같이 본 발명의 재생 가죽시트의 제조방법을 이용하면, 접착제를 사용하지 않고 물리적인 결합으로 재생 가죽시트를 제조하여, 환경오염을 최소화할 수 있다.
