Yarn count: Yarn count is a way of expressing yarn, which is usually expressed by the inch count (S) in "custom weight system" (this calculation method is divided into metric count and inch count), namely : Under the condition of the specified moisture regain (8.5%), in the spun yarn with a weight of one pound, how many skeins with a length of 840 yards per twist are the number of counts. The count is related to the length and weight of the yarn. For example, if a pound of cotton is made into 30 yarns with a length of 1 meter, that is 30 yarns; a pound of cotton is made into 40 yarns with a length of 1 meter, that is, 40 yarns; 1 pound of cotton is made into 60 yarns in length. For 1 meter of yarn, that is 60. Therefore, the higher the yarn count, the finer the yarn, the better the uniformity, the thinner the woven cloth, and the softer and more comfortable the cloth. Obviously, the higher the count of the cloth, the higher the quality of the raw materials, and the higher the requirements for the spinning mill and the weaving mill, so the higher the cost of the cloth. Generally speaking, 30S and above are called high-count yarns, (20S-30S) are medium-count yarns, and below 20S are low-count yarns. (ps: 840 yards is about 768 meters, 1 pound is about 0.45 kg)

Density: Refers to the number of warp and weft yarns arranged per square inch, also known as warp and weft density. It is generally expressed as "the number of warps * the number of wefts". Several common densities such as 110*90, 128*68, 65*78, 133*73, textile fabric descriptions per square inch of warp yarns are 110, 128, 65, 133; weft yarns are 90, 68 roots, 78 roots, 73 roots.
