Abstract

An ultra-hydrophilic wool fabric with wash fastness and a preparation method thereof are disclosed. Nanometer particles are grafted on the fiber surface of the ultra-hydrophilic wool fabric with wash fastness by chemical bonds. The nanometer particles include nanometer silicon dioxide whose particle diameter is 10-800nm. Based on the total mass of the ultra-hydrophilic wool fabric with wash fastness, the amount of the nanometer silicon dioxide is 0.05-5% by mass. The preparation method of the present invention includes the following steps: pretreating a wool fabric with a coupling agent, then adjusting pH value of a reactive solvent, immersing the pretreated wool fabric in the reactive solvent and stirring under constant temperature; adding silicon dioxide particles with a particle diameter of 10-800nm or a solution containing precursor of the silicon dioxide into the reactive 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 ultra-hydrophilic wool fabric with wash fastness of the present invention has the effects of moisture 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 moisture absorbing and quick drying, bacteriostasis, and self-cleanness.
