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

[0022] The chemical fiber manufacturing method of nanometer silver coagulation bath is characterized in that, comprises the following steps:

[0023] 1) Preparation of nano-silver colloid solution: dissolving nano-silver colloid powder in an inorganic solvent to form a 100g / L nano-silver colloid solution;

[0024] 2) Mix coagulation bath solution: add nano-silver colloid solution to the prepared coagulation bath primary solution, stir and mix evenly, and obtain nano-silver coagulation bath solution after filtering;

[0025] 3) Spinning: After pressurizing the fiber-forming high polymer spinning stock solution, it is sprayed out through the spinneret to form a thin stream, and the spinneret is immersed in the nano-silver coagulation bath solution;

[0026] 4) Fibrillation, coagulation and winding: the fine flow enters the nano-silver coagulation bath solution to gradually bind or combine the nano-silver colloid and solidify into fibers, and finally wind the fiber-formed chem...

Abstract

The invention discloses a method for preparing chemical fibers of a nano-silver coagulating bath. 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 a form of colloid and can be very stably bound in the formed fibers, 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 method for making chemical fibers in a nano-silver coagulation bath. 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 fibe...
