The cross section of hemp fiber is more complex than that of ramie, flax, cotton and wool. It is irregular triangle, hexagon, oblate circle, waist circle, etc. The middle cavity and shape are different, and its molecular structure is prismatic, loose and spiral. Therefore, hemp fiber has a good dissipation effect on sound waves and light waves, and it can block strong ultraviolet radiation without special finishing

Hemp fiber is the softest fiber among all kinds of fibers, and its fineness is only one third of that of ramie, which is equivalent to that of cotton fiber. The top of the fiber is blunt and round, without sharp tips like ramie and flax. Therefore, the finished product is particularly soft and comfortable. There are many cracks and small holes distributed longitudinally on the center of the hemp fiber and the surface of the fiber, forming an excellent capillary effect, which makes it good at perspiration and moisture absorption.
