Research on the influence of number of quilted seams, quilted weight and number of quilted layers on jacket shrinkage

Abstract

Product specifications are one of the important criteria to check and evaluate the quality of jackets in industrial garment production. The paper presents the results of the study on the influence of the number of quilting stitches, the weight of the quilting sheet and the number of quilting layers on the warp shrinkage and weft shrinkage of the fabric after quilting. Applying BMA (Bayesian Model Average) technique on R software to process and analyze experimental results. The analysis results show that the fabric shrinkage in the warp and weft directions are both affected by the factors of number of quilted seams, cotton sheet weight and number of cotton layers with coefficients R² of 0.92 and 0.93 respectively. The shrinkage in the warp direction increases with increasing number of quilting stitches, quilting weight and number of quilting layers. The warp shrinkage is 1.4% ÷ 9.7% higher than the weft shrinkage.
