Many previous studies showed that seam appearance as well as performance depends on the interrelationship of fabrics, threads, and the stitch/seam selection and lastly on the sewing conditions, which include the needle size, needle thread tension, stitch density, and the appropriate operation and maintenance of the sewing machine. Present investigation elucidates the effect of blend composition, sewing thread size, and sewing needle parameters on garment seam characteristics (i.e., seam strength, seam strength efficiency, seam puckering, seam stiffness, and drape coefficient). The seam quality characterization is studied through the L9 orthogonal design methodology. In good quality apparels, compatibility of the seams with the functional requirement is very important for serviceability and life of the apparel. Reversibility as well as repairing of seams in the apparel is very limited in the condition of seam failure. Seam strength efficiency is higher for the uniform fiber matrix in the structure of fabrics. The polyester dominated suiting fabrics give minimum seam stiffness because polyester component has low flexural rigidity. The cotton dominated suiting fabrics have less seam puckering due to increase in fabric stiffness.

Seam Pucker

An automated sewing machine controller and a three-dimensional measurement system have been developed to find the optimum sewing condition that minimizes seam pucker. It is already known that there are various factors affecting the seam pucker. However, the selection of sewing conditions for reducing seam pucker has relied on the experience of skilled workers. In this study, thread tension, presser foot pressure, and stitch length were chosen as the parameters. Parameter settings were controlled by a computer, which enabled the automatic generation of samples with various combinations of sewing conditions. The seam pucker grade was determined from the scanned three-dimensional sample using a fractal dimension calculation. The optimum sewing conditions for a given sample can be determined from this result. The efficiency of the system was verified by comparing the newly developed method with the existing subjective evaluation method.

Seam Pucker

PurposeThe aim of the present study is to consider the influence of the tensile behavior of fabric and sewing thread on the seam appearance.Design/methodology/approachIn this study, the formation of seam puckering on two elastic and normal woven fabrics was explored. In order to prepare samples, various sewing threads were applied. Test specimens were sewn under five different thread tension levels. Then the appearance of samples was evaluated subjectively to determine their seam puckering grade before and after the laundering process.FindingsThe obtained outcomes of this study present that although sewing thread tension increment decreases the seam pucker ranking in the similar sewing condition, elastic fabrics have a greater seam pucker grade compared to the normal fabric due to the fabric extension and contraction during sewing and after sewing process, respectively. In addition, the elastic strain of the sewing thread is the key factor that determined sewing thread's tendency to make seam puckering. Moreover, the laundry process due to the relaxation of the sewing thread decreases the seam pucker grade.Originality/valueThe consistency of the tensile property of fabric and sewing thread is a crucial parameter in improving the seam appearance and obtaining a smooth seam.

Plate Spring

The paper presents the tension regulator of the Shuttle thread of the sewing machine, which consists of an arc-shaped plate spring, has two holes, the first for fixing the screw to the side surface of the bobbin cap and the second for the adjusting screw. In this case, the width of the plate spring along the entire length is the same. A disadvantage of the known design of the Shuttle thread tension regulator is that it is not possible to provide thread tension due to changes in the pressure force of the plate spring along its length in the areas of contact with the thread passing between the plate and the side surface.
