Läder och dess ursprung

Läder och dess ursprung

Läderindustrin är en av de äldsta i mänsklig historia. Våra mest avlägsna förfäder använde skinn för att skydda deras kroppar, händer och fötter. Läder är tillverkat av huden hos alla däggdjur, reptiler, fåglar eller fiskar genom en process som kallas garvning. Denna process bevarar huden som annars skulle ruttna snabbt.

Numera omvandlas åtminstone hälften av det producerade läderet till skor och cirka en fjärdedel till kläder. Endast cirka 15% används för möbler och resten förvandlas till lädervaror och andra konsumentprodukter.

På grund av dess hållbarhet och komfort har läder alltid använts för klädsel av möbeltäten eller transportmedel. De första läderna gjordes av kohud, kohud, svinskinn, vattenfåglar eller getskinn. Skinnet kom från djur jagade eller uppfödda för mat. Den nuvarande trenden är att de flesta klädselsläder kommer från nötkreaturhuider (dvs kohud) eftersom dessa är lättillgängliga och bättre anpassade till skaparnas, tillverkares och kunders behov av idag.

Långt ifrån att förlora sin popularitet är läder fortfarande det material som valts för många människor, inte bara för möbler, vare sig de är kommersiella eller privata, utan också för bilindustrin, luftfarten och den nautiska sektorn.
