Abstract

PURPOSE: To improve the appearance, touch and moisture absorption/desorption by compounding a specific collagen powder with a synthetic resin binder.
CONSTITUTION: Animal tissues treated with an alkali and washed with water according to a conventional method are dipped in water at pH8-10 containing a protease (e.g. papain), L-glutamic acid, a nonionic surfactant (e.g. alkylphenyl ether of polyethylene glycol), sodium chondroitin sulfate, etc., to remove separately fats, polysaccharides, proteins, etc., for purification. Then the animal tissues are adjusted to a pH2 to 5 before wet grinding, and are crosslinked in the presence of a crosslinking agent [e.g. Al2(SO4)3] to yield a collagen fiber agglomerate. The agglomerate is dehydrated to a water content of 70wt.% or below, dried and ground to give a collagen powder of a water absorbing power of 150-300wt.% and an apparent bulk density, of 0.10-0.30g/cc and having a particle content (for particles of 40μm or below in particle size) of 85wt.% or more. Then, 25-150 parts by weight of the collagen powder is added to 100 parts by weight of a synthetic resin binder.
