- Jan 03, 2019 -

Description of the tip of the needle:

1, the tip

The cone at the top of the needle is the tip of the needle. The general needle tip has a circular cross section, and the bottom diameter of the cone is the measuring object. This is the most common type. It is a round needle that is inclined from the top of the pinhole to the tip of the needle and is suitable for various fabrics. If there is no problem with sewing, you no longer need to select another type. Other types include pointed round heads, eccentric round tips, spherical tips, edge tips, and the like.

2, eccentric tip

The relative positions of the needle tip and the needle axis are coaxial and eccentric, and the needle tip is not the eccentric needle tip on the axis of the needle. The direction of the eccentricity of the tip is based on the direction of threading (0°), and there are nine types of cuts from the needle handle to the tip. The last two are the tip of the needle that is out of the diameter of the needle handle.

3, the ball tip

The tip of the needle has a spherical shape with a spherical tip, and has a small ball tip, a middle ball tip, a large ball tip, and a special ball tip. Its main function is to prevent the needle tip from stabbing the sewing material.

The tip of the pinhole near the tip of the small ball is connected to the conical body. The diameter of the ball is about 25% of the diameter of the needle body. It is suitable for tight fabrics or knitwear.

The shape of the tip of the ball is similar to that of the small ball, but the diameter of the hemisphere is about 35% of the needle body. It is suitable for bottoming or sewing knitwear.

The hemisphere of the large ball tip has a diameter of about 50% of the diameter of the needle body and is suitable for clothing bottom seams. The shape of the special ball tip is similar to that of other ball tips. The diameter of the hemisphere is about 75% of the diameter of the needle body, and the tip of the apex has an obtuse angle top, which is suitable for the clothing bottom seam of the lycra material.
