4075 Air Covered Yarn What does 4075 mean?

Recently, our company has grandly launched a 4075 Air Covered Yarn. This product uses spandex as the inner yarn, which has excellent elasticity and softness, making the textile comfortable to wear.

In 4075 Air Covered Yarn, “4075” represents its specific fiber composition and specifications. Specifically, "40" represents the fiber fineness of the spandex in the yarn, usually standard 40D, where the "D" represents "denier", indicating the linear density or fineness of the fiber. In this case, 40D means that the standard linear density of spandex is 40 denier. Spandex is often used to provide elasticity and softness to yarns.

“75” represents the fineness of the fibers used in the outer layer of the yarn. Here, it usually refers to the standard 75D, where the "D" also stands for "denier". This means that the outer yarn uses a standard 75 denier, 36 filaments (36F) covering yarn. This covering yarn is used to cover spandex fibers to protect and strengthen the yarn.

4075 Air Covered Yarn has many advantages such as good elasticity, softness and comfort, moisture wicking, wear resistance, rich colors, environmental protection and energy saving. It is suitable for the manufacturing of various textiles, providing users with high quality and diverse choices.
