Common sense D The number of stovepipe socks represents the thickness of stockings. The higher the D value, the thicker and more durable the stockings are. On the contrary, the smaller the D number, the thinner the stockings, and the less durable they are. D size and temperature: 3D-5D are ultra-thin invisible stockings, which seem to be worn on the body. The even skin color of the legs is more mysterious with the subtle changes in the color of stockings. 8D- 15D are ultra-thin stockings, suitable for temperatures above 25 degrees. 20D-40D are thin stockings, suitable for 18 ~ 25 degrees. 50D-80D are micro-permeable stockings, suitable for 15 ~ 22 degrees. 100D-680D is waterproof stockings, suitable for 10 ~ 20 degrees. 800D-2800D is a medium-thick silk stocking, suitable for temperatures ranging from 8 degrees to 15 degrees. 3000D-5000D is thick pantyhose, suitable for temperature of 5 ~ 12 degrees. Extra-thick cold-proof pantyhose over 5800D are suitable for 3 ~ 10 degrees. Everyone has different cold tolerance, and the temperature difference between north and south in the morning and evening is also different. The above data are for reference only. Material: ordinary nylon yarn: stockings made of ordinary nylon yarn are early products with poor elasticity and low transparency. Unless no one wears it for a special purpose. Crystal yarn: In order to solve the defects of ordinary nylon yarn, crystal yarn was developed. The transparency of this material has been greatly improved, but its elasticity is poor and its feel is rough. Core-spun yarn: high transparency, excellent elasticity, overcoming the defects of nylon yarn and crystal yarn, delicate and smooth to the touch, belonging to injection molding products. Generally, tight weaving is the top grade, and loose weaving is relatively poor. Velvet: Velvet is slightly less transparent than core-spun yarn, but it is much more elastic, which not only makes it feel better, but also increases warmth. Ultra-thin velvet: woven with high-tech ultra-fine fiber full elastic yarn softer than hair, with dense and meticulous texture, delicate touch, crystal clear and good air permeability. Lycra: a new type of fiber introduced by DuPont Company in the United States. This kind of fiber is very easy to stretch, but it can cling to the surface of human body after recovery and has little binding force on human body. Knitwear with a little lycra, it fits comfortably, can stretch freely and move with you. The stockings containing Lycra show better elasticity, color and air permeability. Maintenance: new stockings should be put into the freezer of the refrigerator first, or soaked in clear water before being put into the refrigerator. Take out the stockings after freezing and let them naturally melt and dry, so that they are not easy to break when worn. After the fibers in stockings are frozen, the strength of the fibers will increase. When spinning socks, apply a little super glue or nail polish to the hooked thread, and then gently scrape it flat by hand, so that the hooked thread will stick firmly and will not fall off. Hand-wash with neutral detergent in warm water, do not wring it out, ventilate and dry it to avoid sun exposure. Applicable objects: ● Workers who stand for a long time (such as medical staff and flight attendants) ● People who love shopping ● Workers who sit for a long time (such as computer operators, office workers and long-distance travelers) ● People with varicose veins (such as pregnant women and diabetic edema) ● Female office workers who wear high heels for a long time ● People who are prone to edema of lower limbs ● Skinny leg principle of those who want to have slender legs: The unique principles of nano far infrared ray and venous flow mechanics are adopted to gradually divide and knit Danny. Partial weight loss, press and shape the leg curve! The gradual pressure equalization design can accelerate fat burning and achieve the function of stovepipe and beautiful legs. Because the pressure per square centimeter of elastic socks is very high, it can tightly wrap the leg muscles. When walking or exercising, the calories consumed by muscles will be 2-3 times or even 5 times more than those without elastic socks, so as to achieve the effect of burning fat quickly! Prevention and treatment principle of varicose veins: medical sequential decompression elastic socks establish the highest support pressure at the ankle and gradually decrease along the leg. It is reduced to 70%-90% of the maximum pressure in the calf and 25%-45% of the maximum pressure in the thigh. This kind of blood pressure reduction can make venous blood of lower limbs return, and effectively relieve or improve the pressure of veins and venous valves of lower limbs. Many MMs ask me: 140 Dan, 200 Dan, 300 Dan, 280 Dan, 360 Dan, etc. What do you mean? Answer: Denny number is the unit for calculating the thickness of fabric fibers. The higher Danny's number, the heavier and stronger he is. The lower the Denny number, the thinner and more transparent the fabric is. The greater the Denny number, the tighter and thicker it is, the greater the pressure, and the better the stovepipe effect! Important: Denny number is the unit for calculating the thickness of fabric fibers. The higher the Denny number, the heavier the weight and the stronger the compactness. The lower the Denny number, the thinner and more transparent the fabric is. The higher the Denny number, the tighter and thicker the fabric is. The stovepipe socks marked with D on the market are stovepipe socks, all of which have stovepipe function. Factory direct sales of fiber dream fashion socks is a good choice!
