Preparation method of moisture-absorbing sweat-releasing cotton fabric

The invention discloses a preparation method of moisture-absorbing sweat-releasing cotton fabric, and belongs to the field of shell fabrics. The preparation method includes the steps of (1), adding ammonium polysulfide in ethanol solution, stirring until ammonium polysulfide is dissolved completely, adding in coconut diethanolamide, ammonium persulfate, dimethylethanolamine and hydroxymethyl fattyamine with uniformly stirring to obtain mixed solution; (2), dipping cotton fabric in the mixed solution for 10-20 hours, adding in ammonium hydroxide dropwisely with stirring; (3), rising the temperature to 40-45 DEG C, adding in sodium dodecyl benzene sulfonate with stirring; (4), taking the cotton fabric out, washing the same with absolute ethyl alcohol, and drying; (5), washing with water andthen drying to obtain a product. The shell fabric has light texture, small density and smooth and soft surface, without any harsh feeling when touching skin. Since the cotton fabric has high specificsurface area and high heat
