TABLE 1
As can be seen from table 1, the lightweight antistatic fabrics prepared in examples 1, 2 and 3 have good wrinkle resistance, antibacterial property, aging resistance and tensile strength; from the comparison of experimental data of examples 1, 2 and 3 and comparative examples 1, 2 and 3, it can be found that the fabric base layer prepared from the composite fiber without grafted microcapsules cannot form the composite fiber with a loose porous structure in the thermal swelling treatment, and the fabric base layer with an interpenetrating network structure taking the microcapsules as crosslinking points cannot be formed after the ultrasonic padding treatment and the orthogonal electrostatic field microwave treatment, so that the antistatic performance and the anti-wrinkle performance of the light anti-static fabric are weaker; the fabric base layer is prepared by using the composite fiber grafted with the microcapsule, the nano-alumina cannot be rapidly dispersed among the fibers without thermal swelling treatment, the composite fiber with a loose porous structure cannot be formed, and the treatment liquid cannot be embedded into the microcapsule during subsequent ultrasonic padding treatment, so that the fabric base layer with an interpenetrating network structure taking the microcapsule as a crosslinking point cannot be formed after orthogonal electrostatic field microwave treatment, and the antistatic property and the crease resistance of the light antistatic fabric are weaker; the fabric base layer is prepared by using the composite fiber grafted with the microcapsule, padding is carried out under the condition without ultrasonic, the treatment liquid cannot uniformly fill the composite fiber with a loose porous structure, and cannot be grafted and embedded into the pores of the microcapsule, so that the fabric base layer with an interpenetrating network structure taking the microcapsule as a crosslinking point cannot be formed after orthogonal electrostatic field microwave treatment, and the tensile strength and the anti-wrinkle performance of the light anti-static fabric are weaker; from the comparison of experimental data of examples 1, 2 and 3 and comparative examples 4 and 5, it can be found that when the treatment fluid without grafted p-benzoquinone is used, the anti-aging hindered phenol and the antibacterial indole compound cannot be formed in the treatment fluid, and cannot be grafted with the surface of the microcapsule in a porous manner in the ultrasonic padding treatment process, so that the tensile strength of the light anti-static fabric is low, the polybenzazole conductive path cannot be formed in the orthogonal electrostatic field microwave treatment process, and the antibacterial property, the aging resistance and the antistatic property of the light anti-static fabric are weak; by using the treatment liquid grafted with p-benzoquinone, microwave treatment is not performed under an orthogonal electrostatic field, so that a polybenzazole conductive path cannot be formed, and the antistatic property of the light antistatic fabric is weak.
