Many kinds of fabrics such as cupra fabric, rayon-silk fabric, silk-polyester fabric and silk fabric are now much used as lining and 50S silk thread prevails on the market to sew these lining fabrics.
From the viewpoint of end uses, seam tensile strength and seam puckering of lining fabrics have been measured and authors have tried to find the best kind of thread and length of its stitches for lining fabrics. The results obtained are as follows :
1. 50S silk thread appears not to be suitable for cupra fabric. Instead 80S cotton thread, 80S polyester thread and 80S nylon thread are suitable for cupra fabric, according to the order mentioned above. Five or six stitches per cm of the cloth are preferable to sew in the warp direction with cotton or polyester threads and 4 or 5 s. p. c. for the weft direction sewing. The nylon thread produces better results for both directions of the cloth when the number of stitches is 3 or 4 s. p. c.
2. For union cloth 4 s. p. c. of 80S nylon thread is suitable for both warp and weft direction sewing.
3. Four or five s. p. c. of 50S silk thread is suitable to sew silk fabric in warp direction and weft direction.
