3,the application of the Interlock sewing machine in the production process

(1) For the seaming of the piping

Use the straps to wrap the edges of the pieces in the seams, if you use light to roll. The number of seams on the seam is too large and too thick. If the tailored clothes are worn, it may be uncomfortable, but if the seam sewing machine is used to sew 602 (two needles and four threads) or 605 (three needles and five threads) Stretch stitching, stitching the burrs of the straps, the number of seams on the seams can be reduced from five to three, or 406 (two stitches and three stitches) or 407 (three stitches and four stitches) Stretching) Stitch (to remove the surface of the Interlock sewing machine and remove the decorative line from 602 stitches to 406 stitches), see Figure 8. The sewing aid for the piping can be installed on the Interlock sewing machine, which can reduce the thickness of the slit and improve the operating efficiency.

(2) Stretching after overlocking

After the knitted garments are sewn with the overlock stitches, the seams of the seams are not conformed, and the seams can be covered with the seam stitches. The protruding seams are applied, but the operation of this procedure is often accompanied by a special needle plate and presser foot to fix the slit to make the operation easier to control.

(3) Sewing process of 绱 lace

Due to the width between the two or three stitches of the stitching stitches, a mesh-like stitching can be used to cover the seam of the lace strip directly on the cut piece. There is no need to fold the edge of the piece to prevent loose edges, which can reduce the thickness of the slit and is more comfortable to wear. For example, women's knitted underwear is often sewn in this way.

(4) Folding and seaming process

In order to reduce the thickness of the hem seam, the edge of the garment is often treated with a quilted stitch and then a single crease or a dark stitch, such as a skirt hem, trousers, cuffs, etc., which can reduce the bending The double-folded quilting often occurs as a twisting phenomenon, but this treatment method needs to be completed after the over-seaming and then quilting. If the style of the garment is matched, the 406 (two-needle three-line stretch) stitch can be applied. Fold the garment into a single slit. Combine the two processes into one process to improve production efficiency.

(5) Sewing on elastic fabrics

Because the stretch stitch has strong elasticity, it is especially suitable for the sewing of knitted fabrics or other elastic fabrics, such as knitted t-shirts and underwear. In addition, the stitch stitch can be covered with a mesh-shaped decorative line. In addition to being decorative, the operation of the knitted/sweater-mounted patch pocket can be sewn with the seam stitch, which can reduce the folding. The thickness is easy to operate, and it is not necessary to sew the seam of the edge of the bag to directly sew the patch pocket, which saves the operation process and time.

Through the analysis of the use of the above procedures, it can be seen that the use of the Interlock sewing machine is very wide. For example, the effective use of its performance, the selection of the appropriate type of machine head to apply, and the appropriate sewing aids when appropriate, can better play the tension The high performance of the sewing machine.
