Problems solved by technology

[0005] Although there have been patents related to fiber wear resistance in the past two years, such as in Chinese patent CN 105388078A, the device and method involved are to rub the fiber under a certain tension through a friction roller until it breaks, and record the motor when the fiber breaks. The number of rotations is used as an indicator of fiber wear resistance, but the devices designed are all aimed at the mechanical wear resistance of monofilament fibers or fiber bundles, and cannot be clearly characterized for the wear resistance of conductive fibers.
Moreover, it can only record the limit friction times when the fiber breaks, and cannot record the change of fiber properties during the friction process.
At present, there is no test device and method for the friction resistance of conductive fibers, especially the change of fiber properties during friction

Embodiment 1

[0028] The specific implementation of the conductive and wear-resistant process test is carried out with carbon black coated nylon conductive fiber monofilament as the test sample.

[0029] Select carbon black-coated nylon conductive fiber monofilament as the test fiber, select the tension at both ends of the fiber to be tested as 5N, the speed of the eccentric motor as 30 rpm, the pressure between the friction plates as 5N, and the built-in temperature as 50°C , relative humidity is 30%RH. The conductive wear resistance testing device of conductive fiber in embodiment 1 is adopted to carry out the conductive wear resistance test of carbon black coated nylon conductive fiber monofilament:

[0030] During use, the lower end of the conductive fiber to be tested is fixed with the sample fixing part 12, and then the upper end of the fiber is fixed, and the tension at both ends of the fiber is adjusted to 5N by adjusting the upper fixing part 23, and the pressure between the fricti...

Embodiment 3

[0043] Adopt the step in embodiment 1 to carry out conductive wear-resisting process test to polyaniline coated type polyester fiber monofilament:

[0044] The first step is to take 20 polyaniline-coated polyester fiber monofilaments, select a monofilament sample from them, fix the lower end of the conductive fiber to be tested with the sample clamping part 12, and then fix the upper end of the fiber, and adjust it up and down. The upper end clamping part 23 is used to adjust the tension at the two ends of the fiber to be 10N;

[0045] The second step is to adjust the pressure between the friction plates 22 to stop the adjustment when it reaches the set pressure value of 5N;

[0046]The third step is to wait for the temperature and humidity of the internal environment to reach 25°C and 30% RH respectively, then start the eccentric wheel motor 2 to make the eccentric wheel move at the set speed of 30 rpm, driving the friction plate to reciprocate ;

[0047] The 4th step, obse...

Abstract

The invention provides a wearing resisting process experiment device for conductive fiber. The wearing resisting process experiment device for the conductive fiber is characterized in that the device comprises a component used for adjusting pre-tension of a to-be-detected sample, friction plates capable of clamping the sample, a component capable of adjusting pressure between the friction plates, an eccentric wheel motor allowing the friction plates to do repetitive motion, a counter used for recording the number of friction times, a resistance tester used for testing resistances of two ends of the conductive fiber, a resistance wire used for temperature control of a closed box as well as a humidifier used for adjusting the humidity, wherein friction pieces are attached to the friction plates. The wearing resisting process experiment device can simulate the wear resistance and change of performance in the wear resisting process under the conditions of different temperatures and humidity. The device is simple to operate and has very high practical value in design, selection and research of the conductive fiber.

Description

technical field [0001] The invention belongs to the field of material testing and relates to a testing device suitable for the wear resistance of conductive fibers. [0002] technical background [0003] Conductive fibers generally mean that the resistivity is lower than 10 at 20°C and 65% RH. 8 Ω.cm of fiber. Conductive fibers are different from ordinary fibers. Conductive fibers are widely used in electromagnetic shielding covers, explosion-proof work clothes, anti-static disasters, anti-static fabrics, anti-microwave work clothes, anti-static packaging materials and many other fields. [0004] Conductive fibers are roughly divided into two types: uniform conductive components, such as carbon fibers, and non-uniform conductive components, and non-uniform conductive components, which are further divided into conductive component coating types and blended types. No matter what kind of conductive fiber is, it will inevitably experience various forms of wear in the actual use...
