Using some of ordinary fibers & microfibers to produce knee support for women to improve function performance.

Abstract : The aim of this research is for achieving best fiber material (microfibers) for the production of knee support for women by improving their function of Performance & fabric properties (absorption-compression-resistant fabric for explosion-pilling-air permeability & static electricity). The experimental work was done at the NRC IN Cairo for measuring the knee support efficiency. Six knee support samples were produced with a manual crochet structure with (100%microfiber acrylic)-(50%-50%microfiber acrylic-viscose)-(92%-8%micro fibers acrylic-elastic)- 100%cotton - 100%acrylic-(55%-45% acrylic-cotton).this samples were applied on women at the ages between 40-60 years old they suffer from roughness of knee joint , the experimental method was done according to standard test methods. Which relies on analytical test samples produced under the research &then analyze the data & expressed .According to the quality assessment by radar chart for all measuring, it was found that sample (cotton100%) & the sample (microfibers acrylic-viscose50%:50 %) scored the high quality factor. A questionnaire was done to evaluate the produced sample applied at women and according to practical application sample (microfibers acrylic-viscose / 50:50 %) achieved the best sample for comfort wearing properties.
