Title: Tanning process using hydrophilic oligo-urethanes - opt methylolated, and opt formaldehyde, for leather and hide
Inventor: TRAEUBEL HARRO DR
IPC: C14C3/18
Filed: 1975-01-31
Abstract: Leather or hide is (re)tanned by treatment in an aqs. bath contg. a) opt. methylolated hydrophilic oligo-methane of mol.wt. 300-20,000 pref. 500-3000, and opt. (b) formaldehyde or its precursor. The use of oligo-urethane obviates toxicity problems encountered with low mol.wt. diisocyanate and the process is thus industrially feasible. The tanned products have low density since the fibres are not heavily tanned, and unlike chamois skin of prior art they can be easily dyed by usual dyes to give light fast, flexible, soft, 'breathable' materials. The oligo-methane contains hydrophilic polyether segments and methylol gps. and are used as clean aqs. solns. or aqs. sols. of particle size 50 m mu. The oligo-urethane can contain ionic gps.
