The static electricity properties of textile products are very important, especially when clothing comfort is the main subject. In this study, four sets of clothing fabrics containing 33 systematic and 18 non-systematic woven fabrics in total were used in order to examine the electrostatic charging properties. A testing mechanism which provides static electricity by the triboelectrification method was manufactured, and electrostatic voltage values occurring on the fabric samples were measured by an electrostatic voltmeter simultaneously with the testing mechanism. The repeatability of the results was checked by using polyester and cotton systematic woven fabrics. After this stage, the effects of fabric structural parameters and the rubbing period on electrostatic charging properties were evaluated. Moreover, non-systematic commercial woven fabrics were also tested in the study. In the last section of the experimental part, the best clothing and lining fabric combinations were reveal...

Woven textile fabrics of cotton, polyester, nylon and polypropylene have been tested for contact and frictional electrification under similar experimental conditions. These fabrics are contacted and rubbed with steel and polytetrafluoroethylene (PTFE) for investigating electrostatic charge generation and dissipation properties between polymer-metal and polymer-polymer materials. Measurements have been made for the charge buildup after first initial contact/rubbing; the charge buildup during 50 contact/rubbing cycles; and the half-life discharge time. It is observed that the charge generation during rubbing and contact with steel is less than that with PTFE. It is also observed that the samples charged by rubbing decay quickly as compared to the contact charged samples. The findings indicate that with a few exceptions, the charge magnitude and polarity follow the triboelectric series.

The electrical properties and electromagnetic shielding effectiveness of raw, dyed and softened, and treated with an antibacterial finish polygiene VO-600 cotton/antistatic polyester fabrics of two knit patterns, such as 1 Â 1 rib and half-Milano rib, giving a very similar appearance for the fabric surface and having four polyester percentages (10%, 20%, 30%, and 35%) were investigated. Surface and the volume resistivity were measured according to EN 1149, and the effectiveness of electromagnetic shielding was determined according to ASTM D4935-18. The effect of individual factors (fiber composition, knit pattern, technical side, and treatment) and their complexity on the electrical properties of fabrics was evaluated by applying analysis of variance. The research revealed that the fiber composition of fabrics as an individual factor has the greatest influence on electrical properties. Electrical resistance decreased with the increasing percentage of polyester. Half-Milano rib fabrics were significantly more resistant than 1 Â 1 rib fabrics. Raw fabrics were less electrically resistant than dyed and softened fabrics, and treated with antibacterial finish fabrics. Antibacterial finished fabrics were more electrically resistant than dyed and softened fabrics. The analysis of variance revealed that the complexity of investigated factors, such as fiber composition, knit pattern, and treatment, has a significant impact on fabric resistivity for both technical sides. Therefore, when selecting knitted fabrics with a very similar appearance for final applications in daily clothing, not only the impact of individual factors on their performance must be evaluated. The shielding effectiveness of the fabrics was too low to protect against electromagnetic waves.
