Why do stockings have 80D, and how many D's? What does d stand for?

D (Denny): It refers to the fineness unit of sock fiber, and it is called D according to how many grams the fiber weighs per 9000m. The thickness of stockings is based on denier, and how many "D" or "denier" are marked on the package of each pair of stockings. Therefore, the higher the number "D", the higher the relative weight and the higher the thickness of the fiber.

80D means that every 9000m optical fiber weighs 80g.

You can choose 50D, 60D, 70D, 80D and 120D in early spring when it is still cold, 20D, 40D, 50D, 60D and 70D in warm spring, 15D, 20D and 40D in early summer and 8D, 10D and/kloc in summer. You can choose 20D, 40D, 50D, 60D and 70D in warm early autumn, and 60D, 70D, 80D, 120D and150d in cold late autumn. In winter, 80D is enough for those who are not afraid of cold, and 120D, 150D, 200D, 300D or more. For example, 1600D is almost as thick as cotton trousers.

Ultra-thin stockings are made of core-spun silk or spandex. Generally, the materials of ultra-thin stockings are spandex cotton blended yarn, velvet silk, spun silk cotton blended yarn and Lycra.

The smaller the number of "D", the thinner the stockings are. The more durable the socks, the higher the "D" value. Generally, 40-60D are spring and autumn socks, and over 60D are winter socks. The average number of nests in summer stockings is below 20 days, which is cool, light and transparent. Now the ultra-thin stockings even reach 5 days. Choose thick and warm velvet stockings in winter. The stockings with a thickness of more than 1600D are similar to autumn trousers. If you count the stockings made of Lycra, you can actually wear them instead of cotton wool and long pants in winter as long as 25D. This is why wearing stockings is better than long pants. If 1600D stockings are compared to the thickness of autumn trousers, then 25D lycra stockings or 60D velvet stockings with the same warm, moisture-proof and windproof effects are many times thinner and more comfortable and light than autumn trousers.
