THE STUDY FOR NUMBER OF STITEHES THAT HAVE AFFECT TO THE STRENGTH OF THE SIDE SEAM UNDERWEAR FOR MAN

Abstract

The objectives of this research were search for stitches rate the strength of the seam on the right side of the underwear for men, in order to apply underwear for men the highest benefits. By using standard quality control by ISO 13935-2:1999 which tested by extract of Grab approach tensile tester using the handle or grip of the test specimen holder only common in the center areas. That stitches at the distance of 11 12 13 and 14 stitches found that along the seam binding the foot of 4 lines chain Stitches in number of 14 Stitches with the most strength is the characteristics stitches frequency more than others. The characteristics of thread looped chain 14 stitches, Stitches more density than others. The average tensile strength at the peak (Force @ Peak) equals 562.584 Newton and the average tensile strength deficit (Force @ Break) is 518.682 Newton compared with the seam binding the foot of 4 lines Stitches chain 11 Stitches specified in the Standard Industrial panties men average peak tensile strength is less than. Thus resulting in a very strong one, so the seam binding foot of 4 lines stitches chain 14 stitches be suitable for seam side underwear male model of Boxer (Boxer) at fabric knitted Interlock (Double jersey), that have a mixture of cotton 95 percent, 5 percent rubber stretch.
