Mechanical properties of sewing stitch performed in frozen state

The proposed solution for increased automation in clothing production by freezing the textile involves sewing operations in frozen state. The realistic applicability of such technology could be limited, amongst other issues, by the possible loss of mechanical properties of the sewing stitch performed in that way. This work represents an experimental investigation for the evaluation of the influence of textile freezing to possible changes of mechanical properties with respect to the normally performed sewing stitch. A series of standard extension tests are done on specimens of sewing stitches performed both in frozen state and in usual way for comparison. The differences in the results are analysed statistically for a representative textile material.
