| Résumé : |
Ultraviolet (UV) and heat resistance are very important qualities for leather products. We recently developed an environmentally friendly finishing process for improving the UV- and heat resistance of chrome-free leather. We previously reported and demonstrated some promising results from coating tocopherol, a natural antioxidant, onto the grain layer of leather. Tocopherol (Vitamin E) is a potent free radical scavenger and highly protective agent for collagen fibers against UV damage. This antioxidant has improved the UV- and heat resistance of the leather product. To help prevent over-drying, glycerol, a humectant, is added to tocopherol to not only maintain proper moisture content, but also to improve the UV and heat resistance of leather. The mixture of glycerol and tocopherol is applied as an emulsion with sodium dodecyl sulfate (SDS), as an emulsifying agent and coated the grain layer of that leather. Following exposure in a Fade-ometer, the treated samples were evaluated by colorimetric and mechanical testing for the efficacy of UV- and heat resistance. Data showed that leather coated with glycerol/tocopherol exhibited significant improvement in color fading resistance against UV radiation and heat. |
