K Its thickness is specifically distinguished as follows:
Ultra-thin type: 6D, 8D, 10D, 12D, 15D, 20D.
Medium thickness type: 40D, 50D, 70D, 75D, 80D, 100D,10d, 120D, 150D, 180D, 200D.
Thickened type: 300D, 380D, 400D, 500D, 600D, 700D, 800D, 1000D, 1200D, 1500D, 1600D.
Ultra-thick type: 2200D, 2400D, 2500D, 2600D, 2800D, 3000D, etc.
Usually 3D-20D is suitable for 25 degrees; 80D-300D is suitable for 15-25 degrees; 300D-600D is suitable for 10-20 degrees; 700D-900D is suitable for 5- 15 degrees; 1000D-2000D is applicable to 5- 10 degrees.
How thick is stovepipe socks 200D:
D is the unit of raw material thickness. The bigger the number, the finer the yarn, the rougher the product made of thick silk, the thicker the socks, and the simpler the workmanship (thick socks don't have to worry about elasticity or scratch).
200D is airtight. However, compared with the hundreds of days in China, it is still relatively thin, so girls should never ask little girls why their socks are not thick. Although socks look thin, they are made of special materials, so you can feel them when you put them on.
