Antistatic Performance Experiment of Fabric Friction Electrostatic Tester

Author:QINSUN Released in:2023-09 Click:24

Static fabric friction tester is mainly used to test the antistatic performance of fabrics. It is a commonly used testing instrument in laboratories. Qisnun Precision Electromechanical Technology Co., Ltd. is the manufacturer. Welcome customers who need to inquire in time.

Anti-static performance test The test mainly studies the influence on the anti-static performance of fabrics from four aspects: main yarn selection, main yarn selection, fabric structure and waterproofness. The specifications of the main yarn and conductor yarn used are: T/C65/35 13.06tex×2, acrylic yarn 45tex, polyester network yarn 51.11tex, carbon black conductor yarn 28.12tex and stainless steel filament with a diameter of 0.06. mm. According to the design requirements of the orthogonal test and the limits of the test conditions, the type of conductive yarn and the tightness of the fabric are used.ilized as two tiers, and the main material and fabric weave are used as three tiers. The factors and levels are shown in Table 1. The conductive wires are distributed in the weft direction with a spacing of 0.6 cm.

Since the levels of each factor are not equal, the quasi-level method is used to transform the problem of unequal levels into a problem of equal levels: according to practical experience, from the first two and second factors of factor B A best level is selected from the levels as the virtual level of the third level, and a best level is selected from the first and third levels of the factor D as the virtual level of the second level, so that the factors B and D become three levels, transforming the problem into four factors and three levels. Using the L9(34) orthogonal table to organize the tests, a total of 9 tests were performed. By taking the voltagetribostatic of the tissue as an investigation index, an orthogonal test chart as shown in Table 2 is established, and the actual horizontal arrangement of factors B and D is in parentheses.s.

Tribostatic tension test

Wash all samples before testing to remove spinning oil, mud, etc. when testing results. The sample was conditioned for 1 day at a temperature of 16°C and a relative humidity of 55%, then tested on a static fabric friction tester. Frictional static tension was used to characterize the antistatic performance of the fabric. Sample size: 6cm × 8cm, 4 samples each time. Abrasive size 20 cm × 2.5 cm (nylon). In order to avoid the large difference in test results caused by the distribution of lead wires depending on the sampling position, in this test, one lead wire of the sample wasalways aligned with the same diameter position when clamping the specimen to ensure that the test data is comparable.

Analysis of variance

According to the results of the analysis of variance on the influence of various factors on the static friction tension, the main material of the wire (factor A) has a very significant impact on the antistatic performance of the fabric and the material of the conductive yarn (factor A) B) It has a significant impact on the antistatic properties of fabrics, while the structure of the fabric (factor C) and tightness ( factor D) do not have a significant impact on the antistatic properties of fabrics.
