Problems solved by technology

[0002] At present, the demand for antibacterial and deodorizing textiles is relatively high, especially chemical fibers for weaving socks and T-shirts, which are woven with special cross-sectional shapes of chemical fibers The fabric has the function of moisture-wicking and perspiration, but it cannot play the function of antibacterial and deodorizing from the material performance; 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, the method of combining nano silver with fabrics or fibers to achieve antibacterial and deodorizing functions is simply to smear and soak silver ion solution on the fabrics or fibers. The fabrics produced by this method will soon lose their antibacterial and deodorizing properties after washing. function of

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the preferred embodiments of the present invention.

[0022] The preparation method of nano silver wet spinning chemical fiber is characterized in that it comprises the following steps:

[0023] 1) Preparation of nano-silver colloid solution: dissolving nano-silver colloid powder in an organic solvent to form a 50g / L nano-silver colloid solution;

[0024] 2) Preparation of spinning stock solution: mixing the fiber-forming high polymer organic solution with nano-silver colloidal solution, then stirring, filtering and defoaming to obtain the spinning stock solution;

[0025] 3) Spinning and winding: Spin the spinning dope through the spinneret and enter the coagulation bath to form fibers, and finally wind the fiberized chemical fibers into fixed packages.

[0026] It should be pointed out that the volume ratio of the fiber-forming high polymer organic solution and the nano-silver colloid solutio...

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 ...
