An Environment-friendly Leather-making Process based on Silica Chemistry

Liu Yuansen,Fan Haojun,Xia Chunchun,Peng Biyu (National Engineering Laboratory for Clean Technology of Leather Manufacture,Sichuan University,Chengdu 610065,China)  
An environment-friendly leather-making process,involving lime-free liming process and chrome-free tanning process based on sodium silicate coupled with enzyme and nano-SiO2 respectively was investigated,meanwhile,the environment-friendly characteristics of this process and the hydrothermal,mechanical properties of resultant leather were evaluated.The result indicates that the lime-free process has equivalent effect on fiber opening compared with conventional liming process,and the physical strength and shrinkage temperature of the resultant leather were all higher than the stipulated standards of chrome-free leather.Whilst the values of total solids (TS),total nitrogen concentration(TNC),biochemical oxygen demand (BOD5) and chemical oxygen demand (COD) are lower than the conventional process,showing reductions of 72%,55%,45% and 31%,respectively.Further,wastewater from experimental treatment showes more easy biodegradability than that of control treatment.More importantly,the lime sludge and chromium are considered almost zero discharge because of no utilization of lime and chrome in this novel process.
