Industrial Sewing and Upholstery Thread

Additional Information:
Just a few years ago, there were only three common sizes of thread in the U.S. Thin threads were labeled 50 wt., regular weight threads were labeled 40 wt., and heavy threads were labeled 30 wt. These numbers, 30, 40, and 50, were borrowed from another standard, known as the Gunze Count standard, establish by thread factories in Japan. If a thread was labeled as a #40 or 40/3 in Japan, it was labeled a 40 wt. thread in the U.S. Likewise, if a thread was labeled #50 or 50/2 or 50/3 in Japan, it was called a 50 wt. thread in the U.S. The problem is that a 50/2 thread and a 50/3 thread are different. The first number follows the Gunze Count standard and indicates the thread size. The larger the number, the finer the thread. The second number indicates the number of strands, or plies, twisted together. Obviously, a 50/3 is heavier than a 50/2 because it has three strands of a size 50 thread twisted together and the 50/2 has only two. The misunderstanding in the U.S. weight system came about because importers started labeling #30 thread as 30 wt., #40 thread as 40 wt., and #50 thread as 50 wt., regardless of the number of strands comprising the thread. That means a 50/2 and a 50/3 thread were both labeled as 50 wt. thread even though one is 50% heavier than the other. As a result, many products that use the weight classification have labels that are inaccurate.
