ABSTRACT

Sewing machines are normally considered general working and from the perspective of its technical features sewing machines could be classified as shown in Figure 4.1.

1. Basic sewing machines comprise machines that sew with a lock stitch and multi-thread chain stitch. These are mainly intended for attaching garment components that are not exposed to high amounts of loads  during wear using a lock stitch. Garment components that undergo higher load during wear require basic sewing machines that utilise multi-thread chain stitch (Araujo 1992; Anon 1993; American Efird 2014).
