From the above table 1, it can be seen that the thermal conductivity of the towels prepared in examples 1-3 is 185W/m.k and the thermal conductivity of the towel prepared in comparative example 1 is only 40W/m.k, the moisture absorption rate of the towels prepared in examples 1-3 is 136% of 128, and the moisture absorption rate of the towel prepared in comparative example 1 is 30%, which indicates that the towels prepared in the present invention can rapidly conduct the heat on the surface of the human body when in use, so that the user feels cool and cool, and the moisture on the surface of the skin can be rapidly absorbed when in use, so as to achieve the drying effect.
The foregoing is merely exemplary and illustrative of the principles of the present invention and various modifications, additions and substitutions of the specific embodiments described herein may be made by those skilled in the art without departing from the principles of the present invention or exceeding the scope of the claims set forth herein.
