Problems solved by technology

[0004] The present invention aims to overcome the existing method for testing the chlorine resistance of spandex, which is complex, cumbersome and difficult to realize industrial automation; and the result obtained by the traditional line marking method is only the breaking strength retention rate of spandex yarn, which cannot be obtained. The specific fracture failure time of spandex yarn is not applicable to the production and application problems in the clothing industry. A method and device for testing the chlorine resistance performance of spandex yarn used in the clothing industry are provided, which can effectively detect the chlorine resistance time of spandex yarn. It provides an effective reference for the application in the industry, and can save the cost of manual operation and realize industrial automation

Embodiment 1

[0045] Use the above-mentioned device to measure the chlorine resistance of spandex yarn in the spandex yarn cake numbered A3 as follows:

[0046] (1) Take the spandex yarn cake to be tested, and make 6 sample circles 10 with a diameter of 15±2cm by winding the spandex yarn in the spandex yarn cake for 2 circles, respectively numbered as A31, A32, A33, A34, A35, A36;

[0047] (2) Hang a heavy vertical iron ring 11 with a mass of 5.8g on each sample ring, and fix the sample ring with the heavy vertical iron ring on the elastic support of the sample frame;

[0048] (3) Add 180L of test water into the measuring pool, add residual chlorine adjusting solution through the first dosing module, add acid and / or alkaline pH adjusting solution to the second and / or third dosing module, and use the remaining test water. The chlorine value is kept at 3.5±0.5mg / L, the pH value is kept at 7.6±0.5, and the residual chlorine adjustment solution is the mass fraction of available chlorine (calcu...

Embodiment 2

[0054] Use the above-mentioned device to measure the chlorine resistance of spandex yarn in the spandex yarn cake numbered B3 as follows:

[0055] (1) Take the spandex yarn cake to be tested, and wrap the spandex yarn in the spandex yarn cake twice to make 6 sample circles with a diameter of 15±2cm, which are numbered as B31, B32, B33, B34, B35, B36 ;

[0056] (2) Hang a heavy vertical iron ring with a mass of 5.8g on each sample ring, and fix the sample ring with the heavy vertical iron ring on the elastic support of the sample frame;

[0057] (3) Add 180L of test water into the measuring pool, add residual chlorine adjusting solution through the first dosing module, add acid and / or alkaline pH adjusting solution to the second and / or third dosing module, and use the remaining test water. The chlorine value is kept at 3.5±0.5mg / L, and the pH value is kept at 7.6±0.5. The residual chlorine adjustment solution is to make the mass fraction of available chlorine (calculated as Cl...

Embodiment 3

[0063] Use the above-mentioned device to measure the chlorine resistance of spandex yarn in the spandex yarn cake numbered C3 as follows:

[0064] (1) Take the spandex yarn cake to be tested, and wrap the spandex yarn in the spandex yarn cake twice to make 6 sample circles with a diameter of 15±2cm, numbered C31, C32, C33, C34, C35, C36 respectively ;

[0065] (2) Hang a heavy vertical iron ring with a mass of 5.8g on each sample ring, and fix the sample ring with the heavy vertical iron ring on the elastic support of the sample frame;

Abstract

The invention discloses a method and a device for testing the chlorine resistance of spandex yarn used in the clothing industry. The drug module is provided with an elastic support and a pressure sensor under the elastic support on the sample frame. Test method: keep the residual chlorine value, pH value and temperature of the test water stable through the first, second and third dosing modules and the temperature control module; wind the spandex yarn into a sample ring and hang it with a heavy vertical iron ring Fixed on the elastic support, the elastic support is in contact with the pressure sensor; when the sample ring breaks, the elastic support leaves the pressure sensor; read the contact time between the elastic support and the pressure sensor, which is the chlorine resistance time. The invention can effectively detect the chlorine resistance time of the spandex yarn, provide an effective reference for the application of the spandex yarn in the garment industry, save manual operation costs and realize industrial automation.

Description

technical field [0001] The invention relates to the technical field of fiber detection, in particular to a method and a device for testing the chlorine resistance of spandex yarn used in the garment industry. Background technique [0002] After the spandex yarn is soaked in a certain chlorine concentration aqueous solution, the physical properties of the spandex will change, the strength will become weak, and finally break due to the influence of active chlorine. When washed with chlorine bleach, or made into swimming suits, the physical properties of spandex yarn will be degraded, or even broken, after contact with chlorine water (active chlorine concentration of 0.5-3.5ppm) in the swimming pool, and the wearing function will be lost. Therefore, major companies have developed a series of chlorine-resistant spandex products, but in the development process, how to find the best chlorine-resistant spandex formula products, it is necessary to test the chlorine resistance of spa...
