Abstract
An investigation has been made to examine the effect of the stress applied to the seam, cloth construction and the stitching technique on the yarn slippage of the woolen cloth.
It was found that the amount of yarn slippage varies depending on the amount of the stress applied to the seam and the cloth construction such as the density and the yarn count. However, certain stitching techniques can prevent the yarn slippage.
In other words, top stitched seams, flat felled seams, double stitched seams which are sewn with an appropriate space between stitching can be used to prevent the yarn slippage. It seems that the top stitched seam is a very effective method, especially when the amount of the yarn slippage and the visual effect of the seam are taken into consideration.
