Role of Knit Spacer Fabrics in Treatment of Pressure Ulcers

Abstract

The article highlights some significant trends in the use of knit spacer fabrics in treatment of pressure ulcers. Healing of pressure ulcer wound is complicated and time consuming. Not only affecting the lives of patients and caretakers, but pressure ulcer also becomes the burden to the government. With the developing wound management techniques, companies have launched different wound dressing designed for pressure ulcer. However, regardless for their high price, it is rare that the wound dressing can provide good wound management and cushioning to the wound. Because of the excellent air permeability and compression performance of weft knitted spacer fabrics, it has been applied in different aspects including medical. A theory has been proposed to design a 3D knit spacer bed sheet that will allow patients with pressure ulcers to be comfortable by ensuring a low friction coefficient between their skin and the material. The friction coefficient will be reduced by not only the structure but by the 70 percent polyester, 22 percent polypropylene and eight percent spandex blend.
