The slippage-based opening at the seam line occurs on the woven fabrics due to
movement in the fabric of the weft yarns over warp yarns (or warp yarns over weft yarns) at
a sewn seam during utilization. Recurrent sitting down and standing up or continuously
sitting down produces a load at the seam line and causes transverse strain at stitch rows.
Owing to this strain, displacement (seam slippage) of the stitch could occur, leading to
opening in the fabric at the seam line. This study is focused on constructing a system
which is based on a non-linear regression mathematical model to predict the seam opening
properties of woven fabric within two different seam opening standard test methods. The
first is the fixed load test method; the other is dynamic seam fatigue. The physical properties
of the fabric and stitch density play important roles in the seam opening of the seat fabric.
The number of weft yarns per unit length, yarn linear density and stitch density were
selected as influential factors. The prediction equation is based on completely randomized
variance analyses model. The coefficients of the curves fitted were computed by means of
non-linear regression analysis. Regression coefficient (R 2) values for these curves were
observed to be highly reliable at more than 0.9. Also the correlation coefficients (r) between
actual and predicted values were very high at more than 0.96.
