The dipped cord fabric is a weft fabric with sparse wefts, the wefts are only convenient to produce and use, the dipped cord fabric is free of wrinkles and tension in the weft direction, and the number of warps contained in unit length is the warp density. The warp density (warp density for short) is a main performance for embodying the impregnated cord fabric. If the warp density is not uniformly distributed, the thickness uniformity of the rubber cord fabric, the mutual infiltration of rubber during the calendering process and the stress consistency of the tire are seriously influenced. Therefore, the measurement and improvement of the cord density of the cord fabric is also an urgent problem in the field.
At present, the measurement of the warp density comprises methods such as a fabric decomposition method, a fabric analysis mirror method, a movable fabric density mirror method and the like, wherein the fabric decomposition method is to cut a sample slightly larger than the minimum measured length at a proper position of a humidity-adjusted sample; a portion of the weft yarn was removed at the edge of the sample and measured with a straight steel ruler to give a minimum measured length of 2cm. The prepared sample is detached point by point from the edge, and the number of the warps in a certain length can be obtained by arranging the warps into a group of 10 for counting. The fabric analysis mirror method is used for measuring the number of warp threads seen in a fabric analysis mirror window and converting the number of warp threads contained in the fabric analysis mirror window to a length of 10cm, and comprises the following specific steps: the fabric is flattened, a fabric analysis mirror is placed on the fabric analysis mirror, one warp is selected and is parallel to one side of a window of the analysis mirror, and therefore the number of warps in the window is counted one by one. The movable fabric density mirror method is characterized in that the number of warp threads in a certain length is measured by using a movable fabric density mirror, and the number of warp threads contained in the length of 10cm is converted, and the method comprises the following specific steps: the fabric is flattened, a fabric densitometer is placed on the fabric densitometer, a graduated scale of the densitometer is perpendicular to the direction of the warps, the screw rod is rotated, and the number of the warps is counted within a specified measuring distance.

The white blank cord fabric meeting the requirements is prepared according to the calculated warp density value of the white blank cord fabric corrected by the formula (2), and the uniformity of the warp density of the dipped cord fabric obtained after the obtained white blank cord fabric is dipped can be better improved.
The reason for improving the warp density uniformity is that the warp density measurement results of the white blank cord fabric and the dipped cord fabric in the early stage are high in accuracy, the relation between the warp density value of the white blank cord fabric and the warp density value of the dipped cord fabric can be well determined according to the warp density measurement result with high accuracy, and then the warp density value of the white blank cord fabric required by the dipped cord fabric with high uniformity warp density value is determined, so that the warp density uniformity of the dipped cord fabric obtained after the white blank cord fabric is dipped is obviously improved.
The method comprises the following specific steps: first, a plurality of white-blank fabrics and a plurality of dipped fabrics are measured, and a plurality of K values are obtained by the following formula (4). And then optimizing according to a plurality of K values to obtain a formula (2), wherein the formula can well improve the warp density uniformity of the dipped cord fabric.
Wherein K represents the relation coefficient of the warp density of the dipped cord fabric and the warp density of the white blank cord fabric, N 2 Measurement of warp Density value, w, for white-shade fabrics 2 For measuring width value, T, of white-shade fabrics 2 Measuring warp density values, s, for dipped cord fabrics 2 The measured width value of the dipped cord fabric;

By adopting the improvement method, after the design of the reed is improved, the relative standard deviation of the full-width warp density of the dipped cord fabric is 3.9 percent, and the improvement effect is obvious. The relative standard deviation is specifically: after scanning rubbing paper rubbing the dipped cord fabric, measuring one warp density value N per N warp yarns in software, wherein the relative standard deviation is the relative standard deviation of a plurality of warp density values N. Namely, the improved warp density uniformity of the gum-dipped cord fabric is obviously improved.
