FIELD: machine building.
SUBSTANCE: collagen containing composition consists of tanned collagen containing waste and products of solution of not tanned collagen. Additionally composition contains a surface active substance. As tanned collagen containing waste there is used tanning powder produced from waste of leather of chrome tannage of shoe industry. This waste is preliminary crumbled in air-dry state to size of fibres to 0.7-0.9 mm. The composition has the following ratio of components, wt %: tanning powder 12-15; products of collagen solution 1.5-2.5; SAS 0.02; water - the rest. The advantage of produced material is simple content of collagen containing composition including mainly collagen containing waste, which facilitates production of material similar to natural leather by chemical contents.
EFFECT: natural and ecologically safe fibrous porous material of increased strength.
