A good needle must have the following characteristics:
1. Smooth needle eye:The eye of the needle must be smooth and flawless, otherwise it will break or fray the stitches as they move back and forth, and eventually make the garment defective. A frayed seam will break after washing the garment several times. The flying tiger company adopts the chemical deburring process, which can not only grind the needle hole, but also make the needle groove and other parts smooth.
2. Tough Needle Point:The needle tip of the needle is a good needle as long as it can be kept in its original state during operation. The hardness design of the needle tip of the flying tiger machine is 750-850HV. This means that the hardness of the needle tip of the chrome plating machine can pass through the steel sheet without any damage.
3. Flexibility:A good needle must have flexibility, the best needle, its flexibility can reach 40 degrees. The flying tiger needle is flexible enough to bend when it receives a sudden increase in resistance (due to the folding of the fabric) and immediately returns to its original state. If the machine needle cannot be restored to its original state after bending, the loss is not only a machine needle, because it will destroy the garment in processing, but also even destroy expensive mechanical accessories, such as hook needle plate.
4. Low penetration:The penetration force required to pass through the suture material must be low. The greater the penetration force, the higher the working pressure on the sewing machine, and finally the life of the sewing machine is reduced. The needle must be high-quality steel wire when selecting the material, and it must be matched with the best heat treatment method to meet this requirement.
5. Stability during sewing operation:Nowadays, high-speed sewing machine needles are used in industrial production. This requires a needle that can maintain stability at high speeds, thereby helping to increase production and make the product more perfect.
