| Abstract: | Generally, the tanned leathers are retanned with a combination of synthetic tanning agents to enhance the properties such as fullness, grain tightness, grain smoothness and roundness. Many of the chemicals that go into the preparation of such synthetic tanning agents are toxic and slow biodegradable. Further, in industrial practice, several synthetic tanning agents are combined to obtain a desired property. In the present invention, a synthetic tanning agent using natural and proteinous waste materials is disclosed, which provides to the leather the properties such as better fibre lubrication, filling of looser ends, softness, shape retention and fabrication comforts without combining with other synthetic tanning agents is reported. | ||
| Startup Options: | Product: Synthetic tanning agent for improved leather characteristics. Application: Leather industry. Focus of the invention: A synthetic tanning agent using natural and proteinous waste materials is disclosed, which provides to the leather the properties such as better fibre lubrication, filling of looser ends, softness, shape retention and fabrication comforts without combining with other synthetic tanning agents. The tanning composition comprises of a biolpolymer selected from sodium alginate, starch and carrageenan either alone or in any combination, protein hydrolysate, sodium metabisulphite and acrylic/ methacrylic acid. |
