RETRACTED: Experiments on pressing elastic-viscous products

Abstract

The effect of various factors on the amount of fluid removed in the technological process of squeezing multilayered raw hides by pressing between plates is experimentally studied in the article. The influence of various factors on the pressing process was determined (for example, the installation of moisture-wicking cloth between the layers of raw hides) and their patterns were established. Results were obtained to determine the effect of moisture-wicking cloth on the efficiency of the process of excess fluid extraction from wet raw hides with the pressure on leather products clamped between the lower and upper plates from 11 to 18 kN/cm2. The installation of fibrous cloth of the BM brand increases the uniformity of fluid removal over the topographic sections of the raw hide, which reduces the storing time after squeezing moisture. The installation of a porous fibrous cloth of BM type between the layers of raw hides eliminates the difficulty of separating the layers of the raw hide. A new method for squeezing out excess fluid from wet raw hides using moisture-wicking cloth by pressing is proposed instead of using metal gratings.
