40/2 Polyester Sewing Thread
"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.
"40/2 Polyester sewing thread" is also referred to as "120 size polyester sewing thread".
Polyester threads are generally durable and resistant to breaking. They provide excellent tensile strength and elasticity, which helps the stitches hold up over time. Polyester threads are resistant to water and sunlight, and they do not fade or lose their color.
In conclusion, 120 size polyester sewing thread is a thread option used for fine sewing projects. It is a preferred type of thread due to its high durability, flexibility, and colorfastness.
