Sewing damage is caused by the resistance of fabric to the penetration of sewing needle during sewing. Such resistance not only comes from the fact that the spaces in the fabric (between the fibres or the yams) are relatively small to the size of the sewing needle, but also comes from the congestion in the needle gap as a result of the fabric materials (viz. fibres and yarns) being pushed into the needle gap (i.e. the gap or hole in the throat plate of the sewing machine, through which the needle passes when penetrating the fabric) during sewing. Therefore, the size and design of the needle gap is very important to the elimination of sewing damage. In the work reported on in this paper, throat plates of different needle gap sizes were designed and the effect of needle gap on sewing damage was investigated. It was found that needle plate having optimum needle gap size can minimise sewing problems.
