| titleOfInvention | A kind of tanning production technique |
| abstract | The present invention relates to a kind of tanning production technique, including order below step：Immersion-fleshing-is lost hair or feathers-pushed away hair-alkali swelling-split-dealkalize-softening-pickling-tanning, then chrome tanning subsequent technique routinely is carried out, in preparatory process, using it is ashless, without sulphur new technology, solves the generation of sulfide, solve with pulverized limestone and caused sludge, solve the problems, such as enterprise's mud discharging.No ammonia dealkalize and less salt technique are employed in tanning processes, greatly reduces ammonia nitrogen discharge and Nacl exhaust emission.The present invention using without sulphur, it is ashless, without ammonia, less salt new technology, the leather hand feeling of production is soft, richness is good, and indices reach EU criteria, outlet Europe, obtain the consistent favorable comment of user. |
