Abstract

The invention provides composite fibers prepared from a lotus leaf extract and a lotus seed extract. The composite fibers are prepared by taking the lotus leaf extract and the lotus seed extract as adding raw materials and taking regenerated cellulose fibers as a carrier. The lotus leaf extract and the lotus seed extract contain multiple nutrient elements, and the nutrient elements exist in the composite fibers in forms such as metal oxides, so that the composite fibers have a function of emitting far-infrared rays and further have effects of accumulating heat and keeping warm; furthermore, the lysine and phenylalanine in zinc, magnesium, aluminum, iron and titanium oxides as well as the lotus seed extract have a better absorption effect on ultraviolet light, so that the composite fibers have an ultraviolet-proof function. The composite fibers provided by the invention contain hydroxyl groups and amino groups, thus having good wet permeability and air permeability; the composite fibersare higher in protein content, so that the skin-friendly property is improved. The composite fibers provided by the invention are glossy, bright and soft, good in dyeing performance, excellent in color fastness, good in fiber softness, washable and high in mechanical strength.

Description

technical field [0001] The invention belongs to the field of light industry textiles, and specifically relates to a composite fiber containing lotus leaf extract and lotus seed extract and a preparation method thereof. Background technique [0002] With the development of industrial textiles in recent years, differentiated and functional plant-derived cellulose fibers have developed rapidly and are of various types, mainly including mint fiber, grass coral fiber, wormwood fiber, and isatis root fiber. One thing these fibers have in common is that the added substances come from nature, are green and environmentally friendly, and are harmless to the human body. However, the current fibers such as mint fiber and grass coral fiber have low strength, and the fiber products are not soft and have poor hand feeling. After the fiber is washed, the extract is easy to dissolve, and the extraction cost is high. [0003] The lotus leaf is derived from the dried leaves of the Nymphaeacea...
