Pattern Sewing Machine Is for Extra Heavy Duty Material - Changes in Needle Penetration into Material

Pattern Sewing Machine for Extra Heavy Duty Material is Thick Thread Reinforcement Stitch (Thick Thread Overlock Knot) technology is widely used to process braided ropes in the safety field, including power ropes and static ropes. The tensile strength of the seam is a crucial factor for mountaineering and climbing ropes, so it is necessary to use suitable sewing equipment to ensure the quality of the seam, including the quality of the seam appearance and tensile strength.

Machine needles face the fabric thousands of times per minute to pierce during the sewing process. Moreover, they come into contact with the needle plate & rotary hook as well as the curved needle after the fabric is pierced. The needles are always subjected to various burdens, especially when they are used for thick or hard fabrics, which makes it very likely that the needle will be bent.

When a needle of Pattern Sewing Machine for Extra Heavy Duty Material with a deformed tip is used, the tip of the needle can cause injury to the fabric, and thread breakage or poor sewing can occur when the needle is used. In addition, the use of bent needles can also cause skipped stitches.

For this reason, we emphasize that we should check for needle deformation once a day and try to identify the problem as early as possible so that we can replace the needles in a timely manner. In order to improve the quality of products, sewing workers are obliged to check the needle twice a day. Some factories even require needle replacement once a day, regardless of whether the needle is deformed or not.

When the needle is out of shape, sewing defects such as shifting of fabric fibers, wrinkling of sewn products, etc. may occur. Of course, there are other reasons for sewing defects besides needle defects. However, it is clear that the accurate selection of needles can reduce many defects.

In order to prevent the warp and weft of fabric fibers from shifting, and to prevent wrinkles in sewn products, it is important to use needles that do not distort the fabric. However, it can be said that the first condition is to use a needle that is not deformed, but there are shoddy needles or imitations of needles on the market. The difference between the authenticity of the packaging is also very important when recognizing regular machine needles and informal machine needles.

◆Needle model and sewing thread model

The quality and thickness of the sewing thread is also one of the most important factors in the stitching strength of mountaineering and climbing ropes. Generally the thicker the thread, the better the tensile properties of the seam, but using excessively thick thread will also affect sewing efficiency (frequent change of bottom thread) and even reduce the quality of the finished product, because the thicker the thread, the larger the needle holes are, which in some cases can damage the fiber structure itself. So it is very important to choose the right sewing thread and needle.
