The tensile data in tables 1.1-1.5 above were tested in the following manner: cutting a cut piece with the width of 5mm from the vamp, testing the tension value of the cut piece when a plurality of point positions enable the special gauze fabric to be separated from the upper fabric by using a tension machine, evaluating the adhesion force of the vamp by using the tension value, wherein the larger the tension value is, the larger the adhesion force is, the smaller the tension value is, and the smaller the adhesion force is. And calculating an average value according to the measured data to obtain final tension data, wherein the data in the table is the range of the tension value of the vamp obtained by testing for 3 times by adopting the method. According to the standard in the industry, the tensile force is qualified only if the tensile force is greater than or equal to 2.5.
According to the data in the table, the vamp of the special gauze fabric is not treated by the treating agent of the special gauze vamp, the range of the tension value is 2.0-2.3N, and the qualified standard is not met.
