Abstract
In the previous paper the results obtained by the statical tensile and shear strength test of the seam of sewn lining fabrics were compared with the experimental results of unsewn lining fabrics.
In the present paper the results obtained by the repeated shear strength and elongation test have been compared with the experimental results of the previous paper.
The results obtained here are as follows :
1. The slippage on a seam line takes place most easily on the silk fabric. The correlation between the slippage width and the seam efficiency of the elongation in statical tensile breaking test is significant.
2. In the tensile test of the fabrics after being subjected to the repeated shear, the cupra fabric breaks on the woven cloth, the polyester fabric gives rise to the sewing thread breakage, and the silk fabric produces the yarn slippage.
3. The repeated shear strength on the seam line is dependent on the kinds of fibers rather than on the properties of woven fabrics.
