Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fabric testing equipment, in particular to a multi-angle testing device for wet-state adhesion of fabric. Background Art
[0002] The wet stickiness of fabric refers to the stickiness caused by the clothing that is worn next to the skin in a liquid state. There are currently two ways to test the wet stickiness of fabric: 1. Test it with the XAD-1 fabric wet adhesion tester. During the test, the tester will fix the fabric vertically and make it contact and adhere to the vertically placed latex material, and then move the sample horizontally driven by a motor to separate it from the latex material, so as to measure the adhesion of the fabric during the separation process; 2. Use a method based on the surface tension test principle to immerse the horizontally clamped dry fabric in a large amount of aqueous solution, and then make a uniform upward movement in the vertical direction to measure the real-time tension on the fabric when it gradually leaves the aqueous solution, which is the adhesion.
[0003] Although both of the above methods can measure the adhesion force, they have the following defects:
[0004] (1) Both methods clamp the test fabric by fixing it on all sides. When separating it from the latex material or liquid, the test fabric is relatively fixed and cannot move freely. It cannot simulate the real state of the human body wearing clothing, which affects the accuracy of the measured adhesion force.
[0005] (2) The XAD-1 fabric wet adhesion tester places the test fabric vertically. When the test fabric is wet, the solution is unevenly distributed on the surface of the test fabric due to gravity, and the liquid carrying rate of the test fabric is uncontrollable, which affects the accuracy of the measured adhesion.
[0006] (3) When a person is wearing clothing and exercising, the fabric and the skin move relative to each other through actions such as swinging arms and running, and the fabric is eventually separated from the skin. During the separation process, the fabric is subjected to multi-angle tension, and the separation movement is not entirely vertical or horizontal. Therefore, the above two methods of separating the fabric by vertical or horizontal movement cannot simulate the real state, affecting the accuracy of the measured adhesion force. Utility Model Content

[0013] The beneficial effects of the utility model are as follows: a movable sample table for placing fabrics horizontally is used to place fabrics, so as to avoid the situation in which, when the fabrics are wet, the solution is unevenly distributed on the surface of the test fabrics due to the action of gravity, resulting in an uncontrollable liquid carrying rate of the fabrics; the sample table for placing the fabrics is movable, and the angle between the transmission line and the movable sample table can be adjusted by the first positioning wheel of the fabric grabbing device, so as to realize the peeling off of the fabrics at multiple angles, thereby improving the authenticity of the simulated separation of the human body and the fabrics; and the grabber is in the shape of a hook, so that the fabrics are in a relatively free state during the peeling off process, and the edge of the fabrics is not fixed, so that the actual state can be simulated more reasonably and realistically, thereby improving the accuracy of the measured adhesion force.
[0014] Optionally, it also includes: a sample stage bracket, a first sample stage positioning seat and a second sample stage positioning seat, the sample stage bracket is arranged in the horizontal direction of the first positioning wheel, the first sample stage positioning seat is arranged in the 45° direction of the first positioning wheel, and the second sample stage positioning seat is arranged in the vertical direction of the first positioning wheel, and the sample stage bracket, the first sample stage positioning seat and the second sample stage positioning seat are all used to place the movable sample stage.
[0015] According to the above description, a sample stage bracket, a second sample stage positioning seat and a first sample stage positioning seat for placing a movable sample stage are respectively arranged in the horizontal direction, vertical direction and 45° direction of the first positioning wheel, so that the movable sample stage can be placed at different angles. The angle between the transmission line and the movable sample stage can be adjusted by the first positioning wheel to control the force direction and the peeling direction of the fabric to be tested on the movable sample stage from multiple angles, thereby realizing multi-angle testing of the fabric to be tested.
[0016] Optionally, the movable sample stage is wrapped with artificial silicone.
[0017] According to the above description, by wrapping artificial silicone on the movable sample stage, the movable sample stage is made closer to the real state of human skin, further improving the authenticity of the simulated separation of the human body and the fabric to be tested, and ensuring the accuracy of the measured adhesion force of the fabric to be tested.
[0018] Optionally, the width dimension of the hook shape is less than 3.5 mm, and the material diameter of the hook shape is less than 0.4 mm.
[0019] According to the above description, the width dimension of the hook and the material diameter are restricted to avoid a large gap between the fabric and the sample table, which may affect the test result of the fabric to be tested.
