Abstract

In the sake of chrome-f ree tanning system, a new more environmental-f riendly combination tanning system has been developed. The in-situ cooperative substance from ferrous sulfate and tetra hydroxymethy l phosphonium sulphate (THPS) was synthesize d of different mole ratios between the two materials. By testing the UV and FT-IR absorption spectra of the Fe( III)-THPS compounds in the job method, it can be found that the most possible mole ratio of n(Fe(II)):n(THPS) was 1:3. And the combin ing site between these two materials was the -SO3- of THPS. At last, pickled sheep skin was tanned with solo FeSO 4, solo THPS, FeSO4 and THPS, Fe(II)-THPS compound. The results show that the hydrothermal stability of leather tanned with cooperative substance was higher than that of leather tanned with single tanning agents, and its shrinkage temperature can reach to 90III. And the gained leather had poor resistance to storage and oxidation.
