preparation example Construction
[0021] The invention provides a kind of preparation method of antibacterial and mildew-proof fiber nib, comprising the following steps:
[0022] The fiber is sequentially combined, shaped, dipped, cured, cut and ground to form a fiber pen;
[0023] The components of the glue solution used in the dipping are adhesives, organic solvents and anti-mildew bactericides.
[0024] In the present invention, unless otherwise specified, the required preparation materials are commercially available products well known to those skilled in the art.
[0025] In the present invention, the fiber preferably includes polyester, nylon or acrylic; the fineness of the fiber is preferably 100-600D, more preferably 200-500D, even more preferably 300-400D. In the present invention, the type of the polyester is preferably DTY, and the crimp shrinkage of the DTY is preferably 15-30%.
[0026] In the present invention, the diameter of the fiber tip is preferably 2 to 5 mm, more preferably 3 to 4 mm, an...
Embodiment 1
[0038] Fiber: polyester filament DTY, 300D / 96F, 200kg; the crimp shrinkage of the DTY is 15%;
[0039] Glue: polyol (glycerol: trimethylolpropane = 2:1): 10kg, isocyanate TDI 15kg, ethyl acetate: 55kg; Wanliqing PL-9800.1kg;
[0040] Determine the number of fiber strands according to the size and diameter of the required pen head, and then combine the fibers, place the obtained fibers in a heat-setting tube, and set them at 215°C for 1 minute; soak the fibers obtained after setting in the above glue dipping in the liquid for 1.0min; the fibers obtained by dipping were cured in a curing box at 130°C for 20min by traction; the obtained cured fibers were cut into bars with a length of 1m, and then according to the actual length of the pen Divide into nib rods of about 3cm, and then grind the obtained nib rods into round heads, pointed heads or axes; wash and dry the formed nibs in sequence to obtain antibacterial and anti-mildew fiber nibs (2.5mm in diameter) .
Embodiment 2
[0042] Fiber: polyester filament DTY, 150D / 96F, 200kg; the crimp shrinkage rate of said DTY is 15%;
[0043]Glue: polyols (ethylene glycol: propylene glycol = 1:1): 10kg, isocyanate polyurethane MDI15kg, ethyl acetate: 60kg; Wanliqing PL-9800.1kg;
[0044] According to the size and diameter of the required pen head, determine the number of strands of fiber strands, then strand the fibers, place the obtained fibers in a heat-setting tube, and set them at 220°C for 1 min; soak the fibers obtained after setting in the above-mentioned Dipping in the glue solution for 1.0min; the fibers obtained by dipping were cured in a curing box at 135°C for 20min by traction; the obtained cured fibers were cut into bars with a length of 1m, and then according to the actual situation of the pen The length of the pen is cut into about 3cm of the nib bar, and then the resulting nib bar is ground into a round head, pointed head or axe; the resulting formed nib is washed and dried in turn to obtain...
