step three: the user touches the finger abdomen and presses the soft feeling simulation base body downwards, because the initial stretching degree of the elastic band and the magnetic field intensity of the magnetorheological fluid are different when different soft feeling is reproduced, the user can feel different soft degrees through the soft feeling simulation base body, the force required by pressing is gradually increased when the soft feeling simulation base body is pressed downwards, the magnetorheological fluid is gradually close to the electrified coil in the downward displacement process, the magnetic field intensity is gradually increased, and the soft feeling of dynamic change can be felt through the soft feeling simulation base body;
step four: monitoring the average value of the resistance value change rate of the conductive fibers, comparing whether the soft touch characteristic value corresponding to the value is consistent with the soft touch characteristic value reproduced by the device or not, if not, transmitting signals to the electromagnetic device and the tensioning mechanism, further changing the magnetic field intensity generated by the coil and the distance between the T-shaped connecting plate a and the T-shaped connecting plate b until the error between the reproduced touch and the real touch is eliminated, and realizing real-time feedback correction of control parameters and dynamic reproduction of the touch.
9. A soft touch reproduction method according to claim 7, characterized in that: the soft touch characteristic value is obtained by testing a soft touch quantification device, and the relationship between the soft touch characteristic value and the distance between the T-shaped connecting plate a and the T-shaped connecting plate b and the current intensity passing through the coil is established through calculation or simulation.
10. A textile online shopping method based on soft touch reappearance is characterized by comprising the following steps: labeling a soft touch characteristic value on an online shopping interface, and enabling a user to perform touch reproduction on the soft touch characteristic value based on the soft touch reproduction device of any one of claims 1-6 so as to assist in choosing and deciding textile goods; soft touch-feel characteristic value transmits for the virtual reality system simultaneously, builds the fabrics that soft touch-feel characteristic value corresponds in the virtual reality environment, through soft touch-feel recurrence device and virtual reality system, gives the user with sense of touch and vision recurrence simultaneously, lets the experience of on-the-spot sense of touch and visual sensation when the user purchases the fabrics on line.
