Method for preparing nano-silver wet spinning chemical fibers

Abstract

The invention discloses a method for preparing nano-silver wet spinning chemical fibers. The method is characterized by comprising the following steps: (1) preparing a nano-silver colloidal solution, namely dissolving nano-silver colloidal powder in an organic solvent to form 50g / L of the nano-silver colloidal solution; (2) preparing a spinning solution, namely mixing a fiber-forming high polymer organic solution with the the nano-silver colloidal solution in the step (1), and carrying out stirring, filtering and defoaming to obtain the spinning solution; (3) spinning and winding, namely spraying the spinning solution in the step (2) through using a spinneret plate, performing fiber forming in a coagulating bath, and winding the formed chemical fibers to be in a fixed package form. The method has the beneficial effects that nano-silver is added into the spinning solution in the form of colloid and can be very stably bound in the formed fibers, so that a fiber material has the effects of resisting bacteria and removing odor; the preparation process is simple, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of chemical fiber spinning, and in particular relates to a preparation method of nano silver wet spinning chemical fiber. Background technique [0002] At present, the demand for antibacterial and deodorizing textiles is relatively high, especially chemical fibers used for weaving socks and T-shirts. Fabrics woven with chemical fibers with special cross-sectional shapes have moisture-wicking and sweat-wicking functions, but they cannot be used in terms of material properties. It has the function of antibacterial and deodorizing; silver ions have the special function of antibacterial and deodorizing in terms of physical and chemical properties. Silver ions can inhibit the reproduction of bacteria and even kill bacteria. At present, nano silver is combined with fabrics or fibers to achieve antibacterial and deodorizing functions. The method is simply to smear and soak the silver ion solution on the fabric or fiber. The...
