| Résumé : |
To meet the growing demand for white garments and pastel shade leathers, a new combination tanning sytem based on acetaldehyde, glutaraldehyde and tetrakis (hydroxymethyl) phosphonium sulphate (THPS) has been developed. The advantages of this tanning system include not only producing white leathers but also completely doing away with chrome. Three separate combinations viz. acetaldehyde-THPS, glutaraldehyde-THPS and acetaldehyde-glutaraldehyde-THPS have been studied. The shrinkage temperature of the leathers obtained using acetaldehyde-glutaraldehyde-THPS combination is 86°C. The organoleptic and the strength properties of the leathers made using this combination system have been found to be on par with that of conventional chrome tanned leather. Aldehyde tanning is known to yellow on ageing and exhibit poor light fastness. However, this new tanning system exhibits good light fastness owing to the presence of THPS. |
