Abstract

A superhydrophilic wool fabric with wash fastness and a preparation method thereof are disclosed. Nanometer particles are grafted on the fiber surface of the superhydrophilic wool fabric with wash fastness by chemical bonds. The nanometer particles include nanometer silicon dioxide whose particle diameter is 10-800 nm. Based on the total mass of the superhydrophilic wool fabric with wash fastness, the amount of the nanometer silicon dioxide is 0.05-5% by mass. The preparation method of the present application includes the following steps: pretreating a wool fabric with a coupling agent; then adjusting the pH value of the reactive solution, immersing the pretreated wool fabric in the reactive solvent and stirring under constant temperature; adding silicon dioxide particles with a particle diameter of 10-800 nm or a solution that contains precursor of silicon dioxide into the reacting solvent in which the wool fabric is immersed, readjusting pH value of the reactive solution, oscillating for a period of time under constant temperature, taking out the wool fabric, cleaning and drying. The superhydrophilic wool fabric with wash fastness of the present application has the effects of water-absorbing and quick drying, and is fully wash wear. The operation of the method of the present invention is simple. A functionality design can be realized in the microcosmic field. The fabric of the present invention simultaneously has multiple functions such as water- absorbing and quick drying, bacteriostasis, and self-cleaning.
