Dralon is also called Bayer acrylic . Dralon is a special-shaped acrylic fiber made by the German Bayer company using the most advanced and environmentally friendly dry spinning process in the world. It has a double T-shaped cross-section, which is unique in the current fiber industry. It has grooves that can retain more still air to achieve a warm effect.

The surface of the German velvet fabric structure is covered with a layer of chemical substances. This layer of substances can make the water on the fabric slide off directly, making it waterproof. The surface fluff can form an air layer, so it has better warmth retention. The manufacturer makes this fabric into women's leggings. and tights for warmth.

① Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb moisture in the atmosphere, with a moisture content of 8-10%, so when it contacts human skin, it makes people feel soft but not stiff.

② Moisturizing properties: Because the cotton fiber itself is porous and highly elastic, a large amount of air can accumulate between the fibers, and air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good moisturizing properties.

③ Heat resistance: When the temperature is below 110°C, it will only cause the water on the fabric to evaporate and will not damage the fiber. Therefore, the pure cotton fabric will have no effect on the fabric when worn, used, washed, printed and dyed at room temperature, thus improving the quality of the fabric. Pure cotton fabrics are washable and wearable.

④ Hygiene: Cotton fiber is a natural fiber, and its main component is cellulose. Pure cotton fabrics have been tested and practiced in many aspects. There is no irritation or negative effects when the fabric comes into contact with the skin. It is beneficial to the human body when worn for a long time and has good hygienic performance.
