Abstract
Objective of this research is creation of an algorithm of a control system of the modes of the intensive hygrothermal influence (IGI) in the conditions of a vacuum when performing the corresponding operations: moistening; the subsequent, if necessary, cyclic drying from within preparation of top of footwear; damp thermal treatment on universal installation with adjustable parameters of a working environment. For assessment of quality of the intensified hygrothermal impact on preparations of top of footwear the integrated criteria of efficiency of processes were used. Ensuring automatic control of parameters of processes of IGV on preparations of top of footwear in universal vacuum installation will allow to control quality of preparations upon transition from performance of one operation to another according to standard manufacturing techniques of footwear.
Highlights
The Intensive hygrothermal Influence (IGI) on capillary and porous materials to which genuine leather belongs provides change to the best physicomechanical indicators of the processed materials [1]
As appears from experimental data of dependence, full and residual lengthenings at 10 MPas from time of vacuum and sorption moistening of skin of chromic tanning have obviously expressed maximum corresponding to moistening within 4 minutes and to a moisture additional weight within 18-19%
At a traditional way of moistening the moisture additional weight in 15% Excess of the optimum humidity received at a vacuum and sorption way of moistening for 3-4% is optimum is explained, obviously, by features of penetration and effect of moisture on internal structure of skin at this way of moistening
Summary
The Intensive hygrothermal Influence (IGI) on capillary and porous materials to which genuine leather belongs provides change to the best physicomechanical indicators of the processed materials [1]. It is known [2, 3] that for achievement of the indicators of physicomechanical properties of previously vacuumized skin demanded by manufacturing techniques [30] of footwear except the coordination of indicators of temperature and pressure of a working environment providing her required relative humidity it is necessary to regulate time of processing.
