[0051] The present invention provides a method for preparing a pressure-sensing smart fabric described in the above technical solution, comprising the following steps:
[0052] fixing a plurality of first conductive yarns to the inner surface of the first flexible fabric base layer;
[0053] fixing a plurality of second conductive yarns to the inner surface of the second flexible fabric base layer;
[0054] fixing the pressure-sensitive material on the first conductive yarn and / or the second conductive yarn in the form of strips or dots;
[0055] positioning the flexible fabric base layer with the conductive yarns and the pressure sensitive material secured thereto and the flexible fabric base layer with the conductive yarns secured thereto such that the first conductive yarns and the second conductive yarns intersect and are secured together Arranged in a matrix, point-like pressure-sensitive materials are distributed on the intersection of the matrix;
[0056] The first co...
Embodiment 1
[0067] A pressure-sensing smart fabric, composed of the following materials:
[0068] The first flexible fabric base layer and the second flexible fabric base layer are pure cotton plain weave fabrics, and the mass per unit area of the fabric is 185g / m 2 , the warp and weft yarn densities are 24tex, the first flexible fabric base layer and the second flexible fabric base layer are subjected to flame-retardant and water-repellent finishing, and the composition of the flame-retardant and water-repellent treatment liquid is: organosilicon softener (amino silicone oil) 5wt% , resin crosslinking agent (triallyl isocyanurate) 2wt%, flame retardant (dimethylphenyl phosphate) 20wt%, fluorine-free water repellent (alkylamine and acrylate polymer) 3wt%, The rest is water; the method of flame-retardant and water-repellent finishing is as follows: the first flexible fabric base layer and the second flexible fabric base layer are placed in the flame-retardant and water-repellent treatmen...
