US Patent:

47846640, Nov 15, 1988

Filed:

Jun 24, 1986

Appl. No.:

6/877743

Inventors:

Marcel Siegler - North Bergen NJ
Ernest Diamont - Fanwood NJ
Joseph L. Suarez - Wayne NJ
Colin D. Quinn - Old Bridge NJ

Assignee:

Seton Company - Newark NJ

International Classification:

C14C 308
C14C 310

US Classification:

8 9433

Abstract:

The present process yields superior leather materials from limed hides, without the use of chromium salts, by combining a series of essential method steps in a sequence which yields leather having a "chrome" character. The present chromium-free tanning process includes the method steps of pretanning a hide with a chromium-free tan until its shrinkage temperature is about 170. degree. to 185. degree. F. , submerging the hide in an acidic brine, having a pH between 2. 5 and 3. 5, and adding (in sequence, and in amounts sufficient to yield specified concentrations of each) pretanning agents, syntans, vegetable extracts, neutralizing agents and retanning and finishing agents, all of which are free from chromium. This method of pretanning, tanning and retanning a hide with a specified sequence of particular concentrations of chromium-free reagents yields a leather product having the characteristics of chrome-tanned leather and which demonstrates superior shrink resistance, resilience and flexural strength. The resultant leather product has particular utility when incorporated into durable, weather-resistant footwear such as military shoes and boots, but is likewise suitable for use in other applications which require durable, attractive leather goods such as handbags and attaches.
