Improvement of the Performance Properties of the Mixed Wool fabrics using yarns with different twist factor

Abstract

in all areas of fiber textile use, whether clothing, furniture, blankets, or carpets. The types of synthetic fibers have increased steadily and their fields have expanded. These fibers have different properties, whether physical or chemical. The research was to be an area in the field of improving the properties of these types of blended fabrics. This research aims to improve some performance properties of woolen worsted fabrics, mixed with polyester fibers and woven from count yarn 60/2 metric , The count was produced using woolly fibers with a 22.5 micron and a length of 85 mm and polyester fibers with 3.3 denier , length 88 mm. and Using four values of the different twist factor (75, 85, 95, 105) using four different mixing ratios of wool and polyester (30% wool - 70% polyester), (45% wool - 55 polyester), (60% wool - 40% polyester), (75% wool - 25 polyester) The reason for the researcher's selection of these count and mixtures is that it is one of the most common count and blends used in wool factories. The researcher then weaved the samples of the fabrics using these mixtures with the textile textureplain 1/1 and then processed them and carried out the laboratory tests on them to measure the effect of the relationship between the different twist factories and the mixing ratios used It is the best parameter to determine the best parameter to be tested for each mixing ratio on the sidelines The properties that the researcher attempted to improve were properties (tensile strength ,
