Objective:
The objective of this cooperative research project is to develop a cotton-based chronic wound dressing.

Approach:
Tissue Technologies has licensed patents related to wound dressings for treatment of chronic wounds. Based on U.S. Patent No. 6,599,523 APreparation of peroxide-oxidized, sulfonated, and phosphorylated cotton , which is jointly owned by Virginia Commonwealth University (VCU) and the United States of America as represented by the Department of Agriculture and licensed to Tissue Technologies a pilot scale process for production of the cotton-based chronic wound dressing will be developed at Southern Regional Research Center. DeRoyale Textiles (cooperator) has an interest in commercializing a phosphorylated cotton wound dressing for treatment of chronic wound. Finishing chemistry treatments of cotton gauze will be scaled up from a laboratory scale to a pilot scale level by the USDA, and will be made adaptable to textile mill production of the chronic wound dressing by the cooperator. DeRoyale Textiles in Powell, TN, (cooperator) is working with the USDA on coordinating the transfer of the finishing chemistry treatments for the chronic wound dressing to their plant in Tazwell, TN.
