"40/2 Polyester sewing thread" is a term used in thread production that provides information about the thickness and structure of the thread. To understand the structure of the thread, let's break down the terms individually:

The term "40" represents the thickness of the thread. It indicates the number of filaments present in a single strand of the thread. Therefore, the expression "40/2" signifies that the thread is composed of 40 filaments.

The "/2" term denotes the ply or the number of strands. In this case, it indicates that the thread is two-ply. The thread is formed by twisting two separate strands together. The layers of the thread are tightly twisted and frequently twisted to enhance durability.
