Hydrophobic skin PP063
Skin conventional fat easily absorb and pass water. Such leather materials are not suitable for the manufacture of military and working products. Developed composition and method of waterproofing leather and shaggy facial fur and materials to manifest products allow to make products with water - repellent properties.
The main advantages of the development.
The most important indicator of natural leather and fur materials, in addition to their physical and mechanical properties, are their thermal protection properties, which are reduced when wet products. Increased resistance to water natural materials gives them hydrophobization, which for the show: nick waterproof in dynamic conditions reaches 3 - 4 hours. The mass of pile materials (fur velour, fur sheepskin) after sprinkling increases by only 0. 2 - 0. 5 % . At the same time, the products retain sufficiently high sanitary and hygienic indicators - air and vapor permeability, respectively, 2, 0 - 2, 3 DM'/(cm ' - h) 2, 1 - 2, 6 mg / (cm' - h), which contributes to the stabilization of the thermal properties of the products with their high elasticity
The main characteristics of the development.
Developed hydrophobization of leather face and the pile and fur materials for naholnik products are characterized by high physical - mechanical indicators, in particular of leather from raw materials of cattle have tensile strength 20 to 24 MPa, and the elongation at a load of 10 MPa is 22 - 29 %
Demand in the market. Natural hydrophobized leather and fur materials can be used for the manufacture of military and work shoes, which operates in extreme conditions and manifest products, primarily made of sheepskin skin coat (coats, hoods).
State of intellectual property protection
Received 4 patents of Ukraine for utility model.
The development readiness status
Hydrophobic skins using the proposed method are manufactured at the enterprise of JSC (Private Joint - Stock Company) " Chynbar "(Ukraine) with the trade name "Vodohray»
