What is yarn count warp 40s Ne?

Yarn count "warp 40s Ne" refers to the thickness of the yarn used in the warp threads of woven fabric, measured in the "English cotton count" system (Ne). The "40s" indicates that there are 40 hanks of yarn per pound, with each hank being 840 yards long, making it a relatively fine yarn. This count is commonly used in textiles for fabrics that require a balance of strength and softness, such as shirts or lightweight garments. The designation specifically highlights its application in the warp direction, which is crucial for the fabric's structure and durability.
