How Can Stitching Work Best?

Garment factories often encounter the difficulty of sewing and ironing cloth. The cotton yarn used in ironing cloth is usually very weak and lacks elasticity due to soaking with resin. Because most fabrics are very tightly knitted, it is easy to pierce the needle for piercing. Therefore, fine needles must be used, and needle No. 10 should be used wherever possible.

The plain needles should be used for woven ironing fabrics, while the knitted non durable fabrics should be stitched with small SES needles so that the needles can be pushed away rather than broken.

The juncture of the collar and cuffs of the shirt should be particularly neat. Therefore, a sharp needle must be used, though the machine needles often damage the cloth.

In view of the limited shrinkage of ironing cloth, non shrinking sutures should be used to make the joints neat and smooth without wrinkling. The suture of man-made fibers can meet this requirement, because the synthetic line is easier.

Therefore, it can be used for continuous thin thread sewing.

When using the synthetic thread, the sewing tension must be carefully determined and the tension should be adjusted to a minimum.

The bottom line tension must be adjusted to: when the end of the seam moves freely, the bottom spindle spindle and the outer sleeve slowly slide down, and the tension between the surface line and the bottom line must be consistent, so that they interweave exactly between the two layers of fabric.

If the pressure of the stitching thread is too large, the tension will be automatically contracted to ease the tension, which will shrink the fabric along the sewing thread and crease the seam.

Often occurs during sewing.

The phenomenon of dislocation on the top and bottom is due to the friction between the two layers of fabric and resistance. On the other hand, the friction between the upper layer cloth and the presser foot forces the lower fabric to move more rapidly.

This phenomenon will also cause wrinkles on the joints. As long as the pressure of the presser foot is lowered as much as possible, and the use of the fine tooth feeder (conveyor), the wrinkling can be avoided.

The fundamental solution to the political problem is to use a sewing machine with a feeding mechanism or a needle feeding mechanism.

The elastic deformation of the easy care cloth during sewing will also cause wrinkles in the joints. This is because the needle holes and groove of the pins and pins are too large, so that when the needle is stabbed, the sewing material is too depressed. The smaller the pin hole or the smaller the groove is, the better.

The most common problem encountered in sewing and ironing cloth is the high temperature generated when sewing needles. In addition, the remnants of synthetic thread will block the needle slot, so it is easy to iron.

The hard chrome needles should be used for sewing.
