APPLICATION of ADVANCED POLYMERIC COMPOUNDS for DEVELOPMENT of LEATHER PRODUCTION

Abstract

Abatement of negative impact of leather industry on the environment is associated with scientifically grounded use of chemical materials and raw materials, with the development of low-toxic and low-waste technologies. A solution of this problem can be development and implementation of pre-tanning and tanning processes alternative technologies with the use of polymeric compounds. To replace traditional pickling process advanced polymeric material based on acrylic acid has been used. It has been found experimentally that application of the polymeric processing intensifies the tanning process, increases the thermostability of leather with more rational use of chemical materials. The content of chrome (III) compounds, chlorides and sulphates in waste water are reduced.
