Résumé : |
Leather is a biopolymer that the industry is very familiar with. Biopolymers can be defined as materials made from biological polymers, e.g. starch, collagen or cellulose. The final material can be comprised of natural (unaltered) or slightly altered biopolymers such as cotton (largely unaltered cotton cellulose) or can be semi-synthetic collagen (such as leather).
Leather is not made of natural hides but rather the hide is modified to remove unwanted components and then the collagen biopolymer is chemically modified to produce a material with specific characteristics. Fully synthetic biopolymers are polymers that are modified and then embedded in a synthesised polymer or biopolymeric matrix, e.g. Mirum is a synthetic blend of biopolymers that do not include petrochemical polymers. |
