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.

The chemical, physical and mechanical properties of flax fibers can be significantly altered with exposure to elevated temperatures and/or changes to the moisture content. In most cases it is preferable to not expose the flax fibers to elevated temperatures or extreme humidities prior to testing and conditioning following methods in ASTM D1776 Practice for Conditioning and Testing Textiles is appropriate. However, in some applications an equilibrium condition of 0% relative humidity is preferred, such as composite manufacturing where the presence of moisture in the fibers can interfere with bonding to a matrix or in test methods such density or FTIR analysis where the presence of moisture adversely affects the accuracy of the results. In those applications it is also desirable that the fibers are not subjected to any unintentional chemical changes which might affect later analysis such as that of lignin or acid detergent insoluble nitrogen. This practice offers time efficient methods of drying materials to an equilibrium condition of 0% relative humidity using elevated temperatures and durations known to be sensitive towards the chemical stability of flax. Currently, research papers published on topics where fibers were dried dont have a standard that can be cited. Many are using different temperatures and different durations, making comparing work challenging. Commonly, temperatures over 100C are used, likely originating from temperatures set in moisture content testing standards. While they effectively dry the fibers for moisture analysis, these temperatures have a significant, negative impact on fiber performance, making them inappropriate for secondary processing or many follow-on tests. In addition to the above, the composites industry is looking to utilize flax fibres as a source of reinforcement. Its anticipated that drying fibers practically and without damage in larger than test quantities is going to increase in demand. The temperatures and durations proposed are intended to be a resource for flax fibre or mat suppliers to composite fabricators. This work is drawing from already known information in the forage industry where drying organic matter is required before chemical assessment and being developed for flax.
