Composite Sewn Seams, part III: The Sewability of Weft Knitted Fabrics.

Abstract

The present work is focused on the interrelations between fabric handle and seam quality – fabric sew ability information on men’s summer outerwear T-shirt out of thin weft knitted fabrics.  To achieve this, an electrical device (fabric resistance to sewing needle penetration – FRNP), was used.  Seam quality – fabric sew ability were studied in terms of subjective evaluation, and objective measurements (fabric resistance to sewing needle –FRNP). It was found that, a) FRNP depends on the sewing direction; and b) the correlation between fabric hand modulus (objective measurement) and fabric hand (subjective evaluation) was very good.Tailorability index of cotton fabrics reaches 77.3%, while knitted fabrics out of cotton –blended Tailorability index reaches 73%, i.e. increasing the blend ratio, increasing fabric tailor ability.In addition, it was found that the ranking correlation coefficient reaches (R = -1), i.e. excellent correlation was found between fabric Tailorability index and fabric fashion ability index.
