New Test Method for Durability of Smart Garment Textile Electrodes after Laundering

1. Scope

The development of standards, which relate to characteristics, properties, nomenclature, and uses of textiles.
Areas of interest include but are not limited to:
* The promotion of knowledge of textiles;
* Textile fibers, both natural and manufactured;
* Yarn intermediates such as laps, slivers, or rovings;
* Spun and filament yarns, including single, plied and cabled yarns and monofilaments;
* Yarns of various polymers made into slit, split, or fibrillated sheets;
* Fabrics made directly from textile fibers or from yarns (of natural or manufactured fibers or any combination thereof) using felting, weaving, knitting, and needle-punching, nonwoven, or other methods of production;
* Textiles used in the manufacture of fabrics, components, or subassemblies for consumer or industrial applications;
* Components or subassemblies used in the manufacture of textile products, such as sewing thread, tapes, zippers, snaps, buttons, hook and loop closures, battings, and interlinings;
* Consumer and industrial textile end products, such as apparel, home furnishings, pile floor coverings, rope and cordage, tire cords, and inflatable restraints;
* Systems for reporting consumer information, such as UV protection by textiles (when such a claim is made for the textile), product and care labeling, and body measurements for apparel sizing;
* Dip pick-up of cords and adhesion of cords used with rubber or other elastomeric material (developed in cooperation with ASTM Committee D11 on Rubber).
The work of this committee will be coordinated with other ASTM committees developing standards with fiber and textile assemblies intended for other uses: C16 on Thermal Insulation; D09 on Electrical and Electronic Insulating Materials; D11 on Rubber; D20 on Plastics; D30 on Composite Materials; E05 on Fire Standards; F04 on Medical Devices; F15 on Consumer Products; F18 on Electrical Protective Equipment for Workers; F23 on Protective Clothing.
Other American organizations having a mutual interest in textiles include: American Apparel and Footwear Association (AAFA); American Association of Textile Chemists and Colorists (AATCC); American Fiber manufacturers Association (AFMA); American Furniture Manufactures Association (AFMA); American Sheep Industries (ASI); American Society for Quality (ASQ); American Textile Manufacturers Institute (ATMI); American Yarn Spinners Association (AYSA); Association of Nonwoven Fabrics Industry (INDA); Cordage Institute; Cotton Incorporated; Industrial Fabrics Association International (IFAI); INDA (Association of Nonwoven Fabrics Industry); International Textile and Apparel Association (ITAA); National Cotton Council of America (NCCA); National Cotton Batting Institute (NCBI); National Fire Protection Association (NFPA); National Institute for Standards and Technology (NIST); Southern Textile Association SYA; The WoolMark Company; Textile Quality Control Association (TQCA); Textured Yarn Association of America (TYAA); US Department of Agriculture (USDA); US Department of Defense (USDOD); US Defense Supply Personnel Command (DSPC).

Rationale

One of the most present examples of smart garments products, already available on the market to customers, are bio-sensing garments which allow for the heart rate and respiration monitoring among other biophysical parameters. These garments are often made of compressive knit fabric in order to ensure a good contact between the textile electrodes and the skin. Therefore, there is a high level of intimacy between the garment and the human body. Especially when used in sportswear applications, which involves high perspiration level, or even as an everyday shirt, for medical applications for example, the garments are expected to be washed often, and as such, they are expected to resist to a minimum of washing cycles. The use of conductive textiles often based on metallic materials can create an issue of durability when they are exposed to some chemicals including compounds found in detergents. Moreover, the mechanical friction generated by the washing cycle can also lead to higher surface resistance and ultimately complete loss of conductivity. The test method directly relates to the durability of the garment and will serve to test and compare smart garments integrating textile electrodes. Despite commercial examples of such product, there is currently no standardized test methods to evaluate on a common and objective basis the durability of such garment in its conditions of use. It would be valuable for consumers, especially considering these products are fairly expensive, to have a clearer understanding of the durability of these garments. The test methods will be used for quality control.

The title and scope are in draft form and are under development within this ASTM Committee.
