Textile properties tests

The availability of an inert electrolyte is of the utmost importance for the development of a quality-control system for textile electrodes. In such a system, it is the aim to test the quality of textile electrodes therefore the condition and properties of the electrode should not be changed or influenced during this quality-control experiment. This condition cannot be fulfilled by using NaCl as electrolyte solution, because during the quality testing, the chloride will affect the properties of the textile electrode tested. 

Property Measurements. All silk samples were conditioned prior to testing at 65% RH and 21°C according to ASTM Test Method D 1776-79, "Standard Practice for Conditioning Textiles for Testing." (8) Tensile properties were determined on an Instron Model 4201 Universal Testing Instrument. Tensile test data were recorded and stored for reanalysis using Instron software, "General Tensile Test, Revision D."... 

Textile measuring and testing processes are used to characterize fibers, rovings, yarns, textile structures, clothing, and carpets. Tests on fiber- and textile-reinforced composites are in a special field. These textile properties are important for trade (such as terms of delivery) and allow a comparison of the product quality of different companies (for example, USTER-Statistics). 

In order to assess the textile properties when it is in usage, textiles are often tested after tailoring them into a garment. 

PPS fiber has excellent chemical resistance. Only strong oxidising agents cause degradation. As expected from inherent resia properties, PPS fiber is flame-resistant and has an autoignition temperature of 590°C as determined ia tests at the Textile Research Institute. PPS fiber is an excellent electrical iasulator it finds application ia hostile environments such as filter bags for filtration of flue gas from coal-fired furnaces, filter media for gas and liquid filtration, electrolysis membranes, protective clothing, and composites. 

Because the mechanical properties of hydrophilic fibers are critically dependent on moisture regain, it is vital that such fibers be tested under constant conditions of temperature and humidity. Standard conditions used in the textile industry are 65% relative humidity and 21°C (1,2,21,96). ASTM D1909, D2118, and D2720 Hst accepted commercial moisture regain values used in the buying and selling of fibers.
