Embodiment 1
[0010] The preparation method of the special-shaped surface needle-punched cotton of the present embodiment, concrete steps comprise:
[0011] The cotton fiber is mixed, opened, carded, screened, pre-punched, stabbed down, stabbed up, and dried in an oven. The heating method of the oven is double-layer electric heating, the temperature is 180°C, and the time is 20 seconds. , the surface is shaped by a shaping roller with a regular irregular concave-convex structure, and then the surface of the cotton layer is instantly cooled by strong cold air to achieve the shaping effect.
[0012] After shaping, the cotton fibers evenly spread on the surface of the needle-punched cotton will form a special-shaped surface structure with different shapes, unevenness and distinct layering. The thickness of the special-shaped cotton layer of the needle-punched cotton accounts for 15% of the total thickness of the needle-punched cotton. Needle-punched cotton with a special-shaped surface has gre...
