preparation example Construction

[0032] The preparation method of the dispersant of the embodiment of the present invention is: mixing polyvinyl alcohol, glycerin and polyvinyl pyrrolidone, stirring at 40-50°C for 30-60 minutes, and drying at 90°C.

[0033] The determination method of the silver-plated hollow microsphere composite filament antibacterial fiber of the present invention adopts national standard GB / T3916-1997 "the determination of breaking strength and elongation at break of single yarn of textile package yarn" ".

[0034] Test method: Take the prepared antibacterial fiber filament section and take a sample with a length of more than 500mm. After adjusting the humidity, clamp it into the holder of the test instrument, so that the distance between the upper and lower holders is 500mm, and then start the instrument. The interval length was stretched at a speed of 500 mm / min until it broke, and the breaking strength was recorded in cN / dtex; the percentage of the increased length at break and the cla...

Embodiment 1

[0036] The preparation steps of the 50 / 50 side-by-side silver-plated hollow microsphere composite filament antibacterial fiber are as follows:

[0037] (1) Component B is made of the following raw materials in parts by weight: silver-plated hollow microspheres 16, dispersant 14, and polypropylene (PP) high polymer chip powder 70.

[0038] Wherein the dispersant is made of the following raw materials in parts by weight: polyvinyl alcohol 11.2, glycerin 2.1, polyvinylpyrrolidone 0.7.

[0039] The preparation method of component B: fully stir and mix the silver-plated hollow microspheres and the dispersant, and use a high-speed shear mixer to mix the mixed materials evenly to obtain a composite powder. Mix the above composite powder and PP high polymer chip powder evenly with a mixer, vacuumize and dry, after cooling, extrude through an extruder, cut the extruded strands and cool them with pure water, and obtain components after drying b.

Embodiment 2

[0042] The preparation steps of the 80 / 20 side-by-side silver-plated hollow microsphere composite filament antibacterial fiber are as follows:

[0043] (1) Component B is made of the following raw materials in parts by weight: silver-plated hollow microspheres 17, dispersant 18, PP high polymer chip powder 65.

[0044] Wherein the dispersant is made of the following raw materials in parts by weight: polyvinyl alcohol 16.2, glycerin 1.26, polyvinylpyrrolidone 0.54.

[0045] Preparation method of component B: adopt the preparation method of Example 1 to prepare component B from the above raw materials.

[0046] (2) Composite filament antibacterial fiber: use PP high polymer chips as component A, prepare component A and component B through a composite melt spinning machine equipped with composite spinning components to prepare silver-coated hollow microbead composite filament Silk antibacterial fiber, the composite type of this embodiment is 80 / 20 (A / B) parallel type.

Abstract

The invention discloses silver-coated hollow bead compound filament yarn antibiosis fiber, which is the filament fiber obtained by composite spinning of a component A and a component B, the component A is a fiber-forming polymer slice (a), and the component B is the antibiosis master batch composed of the fiber-forming polymer slice (a) powder, a dispersant and silver-coated hollow bead. The antibiosis fiber solves the problem of easy fracture of fiber due to large particle size of the silver-coated hollow bead, and the dispersibility of the silver-coated hollow bead is increase. The antibiosis fiber has the advantages of safety, high efficiency, wide spectrum, bacterinertness, and greatly reduced cost. The invention also discloses a preparation method of the silver-coated hollow bead compound filament yarn antibiosis fiber.

Description

technical field [0001] The invention relates to the field of functional fibers, in particular to a composite filament antibacterial fiber and a preparation method thereof. Background technique [0002] Antibacterial fibers usually add antibacterial additives to the inside or surface of the fiber by blending, so that not only the antibacterial agent is not easy to fall off, but also can maintain a long-lasting antibacterial effect through the diffusion balance inside the fiber. Commonly used antibacterial additives can be generally divided into two categories: organic antibacterial additives and inorganic antibacterial additives. Compared with organic antibacterial additives, inorganic antibacterial additives have better heat resistance and safety, and have the advantages of strong antibacterial ability and good durability. Among them, the sterilization performance of nano-silver antibacterial powder has attracted people's attention. Nano-silver antibacterial powder has safe,...
