본 연구는 피혁 제조 공정시 다량의 폐수 및 폐기 물의 발생으로 피혁산업 전반에 걸쳐 심각한 폐기 처리 비용의 부담으로 인하여 생산비용의 상승 요인으로 작용하고 있는 문제 점을 다소 해소하고자 실힘을 실 시하였다 피 혁 폐 기물 가운데 가장 발생량이 많은 세빙조각(Shaving scrap)은 매 립 또는 해양투기시 크롬을 함유하고 있어 환경 오염에 심각한 영홍t을 줌으로 이에 관한 연구가 피혁선진국인 이태리 를 중심으로 활발하게 진행중에 있다.
Treaunent of shaving scrap, a chrome containing solid scrap generated by learher manufacturing process, has been so far depended on mainly incineracion, soil landfill and ocean dumping, which give bad impact on environmem and cause pollution. Shaving sαap generates from the mechanical work for controUing the fìnal thickness of leather and irs main componenrs are collagen protein and parr of chromium compound. For rhe purpose of reusing rhis learher wasre as resources, researches in connection with colJagen fìber recovery, gelable protein recovery and liquid ferrilizer is being speedily progressed. In the experiment, shaving sαap went through wet pulverizing treatmenr by physica! and chemical merhods. Then, making rhe learher sheet evenly, it is mixed with naturallatex and every kind of binding marerials in the container, and the mixtures were passed through experimenral hydraulic press machine and applied to Fourdrinier machine respectively. Lastly, a test for finding out physical strengrh and properries of mulriple-purpose of leather-like material was performed on a continuous learher sheet prepared by the experiment In result, rhe physical strengrh and properties of learher-like material showed nociceable differences according to mixing racio of binding materials, beating methods and the kinds of binding materials selected, and generalJy tear strengrh was the weakest properry among orhers. Also, by the pilot scale experiment in sequence, it was possible to manufacture recycled goods made of soft and hard rypes ofleather-like material with various performances.
