Technical Field

The invention relates to the field of wool top preparation, in particular to a hemp wool top dyeing process.

Background

Hemp fiber is the finest and softest of various fibers, the fiber tip is blunt and round, and has no sharp tip like ramie and flax, so that the finished product is particularly soft and comfortable. The long and thin hollow cavity in the center of the hemp fiber and the surface of the fiber are longitudinally distributed with a plurality of cracks and small holes to form excellent capillary effect, so that the perspiration and the moisture absorption are good. The cross section of the hemp fiber is irregular triangle, hexagon, oblate, oval and the like, the middle cavity is different from the shape, the molecular structure is multi-edge, loose and has spiral grains. Therefore, the hemp fiber has good dissipation effect on sound waves and light waves, and can block the radiation of strong ultraviolet light without special finishing. Hemp is a poor conductor and a good insulating material. Because hemp fiber has a particularly good moisture absorption property, it is possible to easily prevent static electricity accumulation and friction-induced discharge and pilling. The hemp fiber has high heat resistance. Can not change color at 370 ℃, and is suitable for various fabrics. And the hemp fiber is hollow and contains oxygen, so that anaerobic bacteria can not survive, and the hemp fiber obviously has a killing effect on staphylococcus aureus, pseudomonas aeruginosa, white coccus, trichophyton gypseum, aspergillus penicillium and the like, thereby having good antibacterial and health-care performances. Because of their excellent properties, hemp fibers have been widely used in clothing, home textiles, socks, and the like, and have been gaining favor.
