Prediction of bond strength in the fused shirt composites

Abstract

Purpose

Bond strength is an indicator of the quality of the fusing process. The study's primary purpose is to predict the bond strength using easily measurable variables. This study focuses on shirting fabrics fused with woven interlinings and changes in bond strength before and after washing.

Design/methodology/approach

This study attempts to model and predict bond strength of fused shirt composites using an initial screening design followed by full factorial design of experiments. After screening out, those found significantly affecting the bond strength are fabric fiber content, interlining areal weight and fusing temperature. This study proposes the regression models explaining the effect of the three variables on bond strength before and after washing the fused composites.

Findings

This study found that heavy interlinings (250 g/sq.m) require higher fusing temperatures than the lighter interlining (225 g/sq.m). After washing, the bond strength of samples fused at high temperatures reduced in some instances. Maintaining a high temperature without considering interlining weight can lower the bond strength after washing the fused composites.

Originality/value

A combination of screening and full factorial DOE is used to analyze and predict bond strength of composites comprising medium-weight shirting fabrics and heavier weight interlinings used in shirts.
