The instrumentation was based on measuring the force which is exerted by the sewing needle when penetrating the fabric. These results were verified by simple experimental methods, suggesting that modifications to the sewing machine are needed. In addition seam pucker can ending of a research paper be eliminated by improving fabric stiffness locally along the seam area, by incorporating a stiffening material in the seam; this is based upon the technique of pucker elimination found in the author's previous work. The size of the needle plate of the sewing machine seems to affect the degree of damage and fabric "flagging" during sewing damage has been experienced. Stylios, George (1987 a study of problems associated with fabric sewing in commercial garment manufacture.

Part 1 continues previous work by the author on seam pucker welding essays in structurally jammed fabrics; in particular it has been shown that initial Young's modulus of a fabric is a measure of the ability of the fabric to accommodate compressive forces during sewing. Investigations with fabrics revealed that the magnitude of the peak force of each stitch cycle can be related to the degree of sewing damage in the fabric. This tester is based on an instrumented overlock sewing machine, which is interfaced with an IBM PC for computerised data capture and analysis in real time. Based on these results the most important variables in sewing damage were fabric softening and its effective application during finishing, and sewing needle size. The static mechanism of seam pucker proposed previously, based upon the relative magnitudes of bending stiffness of thread and fabric, has been revised by establishing that sewing machine dynamics and pucker are closely related.
