Abstract

The invention relates to a preparation method of pearl-doped modal fibers. The preparation method is characterized by comprising the following steps of grinding pearls into powder to prepare pearl slurry, then performing alkalization, ageing and yellowing on cotton pulp, mixing the treated cotton pulp with the pearl slurry, and performing technologies including filtering, defoaming and ripening toprepare a spinning solution; performing solidification formation on the spinning solution in a spinning solidification bath to obtain nascent filaments; and performing filament spraying and drawing on the nascent filaments to obtain fibers, and performing technologies including defoaming, desulfurization, bleaching, washing, oiling and drying on the fibers to prepare the modal fibers. Mechanicalperformance tests show that the prepared modal fibers substantially accord with the definition of Bureau International pour la Standardisation des Fibres Artificielles to the modal fibers. After the pearl-doped modal fibers prepared with the preparation method provided by the invention is washed for 20 times, the antibacterial rate to candida albicans still reaches 40 percent or above, and the antibacterial rate to staphylococcus aureus still reaches 22 percent or above; and in addition, the pearl-doped modal fibers prepared with the preparation method provided by the invention have certain ultraviolet resistance.

Description

technical field [0001] The invention belongs to the technical field of modal fibers, and in particular relates to a preparation method of pearl-doped modal fibers. Background technique [0002] my country is a big producer of pearls. Pearls contain a variety of amino acids that cannot be synthesized by the human body and a variety of essential trace elements. They have a variety of magical pharmacological effects. Memory, anti-fatigue ability and improve the body's immunity and other functions. [0003] Modal fiber is a regenerated cellulose fiber whose chemical composition is cellulose. Modal fiber is a kind of viscose fiber with high wet modulus, and its performance is better than that of viscose fiber. In recent years, most domestic viscose fiber manufacturers have conducted research on modal fibers. Modal fiber has the advantages of high breaking strength, small elongation at break, high wet modulus and good alkali resistance. The International Bureau of Chemical Fibe...
