The Enforcement of Genuine Leather Product (GLP) Mark——A Talk at the News Briefing Held by The China National Council of Light Industry Vice-President of The China National

Fellow guests and friends from the press: In this newsbriefing we are going to declare to all circles that we shall carry out agenuine leather product mark (GLP) in the leather industry. It is an important measuretaken for exploring a new way of industrial administration under the condition of

Modeling of strain and filtration properties of a semi-finished leather product

A study on deformation and filtration properties of a leather semi-finished product after chrome tanning are presented.The analytical dependences of compressive load on compressive(recovery)strain and moisture content of a leather semi-finished product are obtained.The empirical dependences of hydraulic gradient on filtration rates are determined for various compression ratios of the leather semi-finished product.It was revealed that with an increase in compressive load and moisture content of the leather semi-finished product,the compressive deformation increases.The shoulder section is subject to the greatest deformation,then the belly section and the least deformation is observed in the butt section.A linear relationship has been established between the hydraulic gradient and the rate of moisture filtration through the leather semi-finished product in the directions perpendicular and parallel to its surface.
