Abstract

Collagen surface structure consists of reinforcing fibres and degraded collagen uniformly distributed in them. Pref. the fibres are swirled in a large excess of water to give a dilute collagen slurry, which is laid on a coarse sieve to form a flat structure and if necessary is after-treated.
