The invention discloses a preparation method of a high anti-permeability composite fiber, belonging to the field of modified functional fibers, which is characterized by comprising the following steps: drying the anti-permeability functional masterbatch and a polymer matrix in a mass ratio (9-20) : 100 mixed melt extrusion, the melt is prepared by the spinning assembly through the melt spinning method after metering; wherein, the anti-penetration functional masterbatch is fully mixed with the titanium dioxide porous nano-sheet, the dispersant and the high polymer matrix, It is prepared by drying, melt extrusion and granulation; the invention uses sheet-like porous titanium dioxide nanosheets as fillers, and based on its special two-dimensional sheet-like and mesoporous structure, it can greatly enhance the fiber's reflection, absorption and scattering of visible light , thereby reducing the amount of light passing through the textile, achieving a lower dosage and having a good visual shading effect. |
