A Needle Should Make Extremely Smooth Contact With The Material

The surface treatment of the needle is a key factor to reduce its penetration resistance and friction. Different surface treatments are provided depending on the types of the material.


All types and sizes of needles are hard chrome plated to avoid adhesion, overheating, and abrasion.


For the first time ever the technology for metal cutting has been adapted for making sewing needles. It makes needles more wear resistant and is ideally suited for the most demanding sewing applications. “PD” (Perfect Durability) needles can be expected to last up to 5 times longer than standard needles.


SU/CS: Two coating have been applied to the surfaces of the needle which help reduce the heat from abrasion. The surface layer is Fluorocarbon Surface Treatment to improve smoothness.

ASU: Most suitable for reducing needle heat when sewing delicate and fine materials.

PSU: Compound plating and surface treatment enables the needle to maintain long lasting anti-adhesion properties, suitable for delicate and fine materials.

 Thread Guide To The Needle’s Eye

The function of the groove in the needle is to guide the thread to the needle’s eye with the least resistance possible. For a variety of purposes the shape of the groove may be designed to give optimal results. Organ also provides specialized groove designs including “OSP” with rounded edges or “SRG/SGL” which is spiral to prevent unraveling of multiple ply threads.

 A Hole That Any Thread Can Pass Through Smoothly

During sewing thread, passing through the needle’s eyes, is tightened and loosened alternately. The optimal condition for the thread is to pass smoothly through the needle’s eye with the minimum of strain. To achieve this objective, the needle’s eye must be highly polished to provide the list friction for the thread. Specially custom made needles with over sized eyes can be supplied when using a coarse thread but a thicker needle blade cannot be used.

 Controller Of Loops

Various threads and conditions of sewing can change the size, shape and position of thread loops. Skipped stitches and other problems with seams can often be prevented by maintaining proper loop formation. Providing a scarf (clearance above the eye) facilitates a thread loop formation which allows the looper or hook point to pick up the thread and form a proper stitch. A variety of scarf designs are available to suit various sewing conditions.
