The research is interested in developing techniques for sewing connections between perforated fabrics and satin fabrics to reach the highest degree of quality and efficiency of sewing and thus the functional purpose of clothing and consumption overhaul by specifying some research variables which is the fabric used for implementation where divided into the first two types perforated fabrics (narrow holes - medium holes - wide holes The second satin cloth was used for knitting machines (Singer - Over 5 bits), three types of sewing connections were used (simple socket symbolized by SS, French simple socket, overlock and denoted by ES), three different densities were used for sewing knots (3-5-7) Stitch in centimeters), then conducting practical experiments to determine the specifications of the fabrics under study in the laboratory of the National Research Center in Cairo, then sewing research samples and performing laboratory experiments on them to find out the most appropriate variables in the study that give the highest degree of efficiency and quality of sewing, which is the appearance of knitting and the tensile strength of sewing, where I reached Researcher to determine the best knitting techniques for perforated fabrics with satin fabric in terms of the type of knitting machine, the type of knitting joint, the density of knitting (number of stitches In poison) to achieve the highest efficiency and quality of the final product of evening wear.
