Non-Woven Barrier Properties of External Layer for Wound Matrix

Abstract

Non-woven is commonly used in disposable medical products especially after external surgeries to reduce the infection transfer and improves wound healing. In addition, low its production cost. This study is aimed to engineer the external layer of the wound matrix from non-woven webs and investigation from its barrier performance for fluids leakage, biological odor, and electrostatic charge. The external layer of matrix was suggested to consist of two or three sub-layers from 100% polyester and viscose/polyester (70:30)%. These webs were enhanced by activated carbon (AC) and powdered aloe leaves (A). The final produced samples were evaluated by the radar chart area for the tested properties, in order to determine the best samples produced for the external layer system of the wound matrix. The final samples produced from two and three sub-layers, which were enhanced with powder aloe leaves presented the best performance results, followed by the sample produced from three sub-layers that enhanced with activated carbon, and powdered aloe leaves together. Finally, the activated carbon and powdered aloe leaves that used for enhancing application had a significant effect on the odor absorption with different behavior for each one. The activated carbon absorbed the odor and appeared in its particles. While powdered aloe leaves were absorbed more odor than activated carbon, but it concealment the odor.
