Robust, High Stretch, Flame Resistant, Breathable Textile for Lightweight Moisture Management



OBJECTIVE: To develop a fabric with the durability of a woven fabric and the stretch and breathability of a knitted fabric

DESCRIPTION: Current duty uniforms are made of woven fabrics however, the Army has fielded and has in acquisition garments with woven and knitted materials. The knit can only be placed in strategic locations where stretch and comfort are required and durability is not a critical issue.The use of a durable stretch fabric would increase the comfort and breathability of any woven garment. An FR material that provides the strength and abrasion resistance is needed to survive the wear and tear in the field and provide FR protection. Thewoven fabrics currently fielded are not as comfortable against the skin as knit fabrics, are not as breathable, and do not stretch enough isotropically1 to make the conformal fitting garments necessary for heat management and reduced bulk and movement hinderance3. Knitted fabrics have very low durability compared to woven materials2. Current methods for functionalizing woven fabrics often have detrimental effects to the intrinsic properties of the fabric such as durability, and air or water vapor permeation.4 This novel fabric should have robustness, stretch and breathability to allow for the design of a more comfortable, close fitting uniform that would increase thermal and moisture management of the wearer. This novel textile should have the following properties: 1. Comfort of knit fabrics as measured in terms of bi-axial stretch, water vapor transport, wicking 2. Durability of woven fabrics as measured in terms of abrasion resistance, tear strength, bursting strength 3. The final weight and thickness of the textile should be comparable to the existing textiles used in standard duty uniforms 4. The textile should be no melt/no drip (T), flame resistance is requiredTo develop a fabric with the durability of a woven fabric and the stretch and breathability of a knitted fabric while retaining Army requirements for flame resistance (FR) and vector protection. The improved fabric properties will enable the manufacture of comfortable fabrics, conformal garments, with good heat management, and garments for a variety of applications both military and civilian. The new textile will have the above attributes and maintain the variety of finishing processes currently in use, including Dye-ability, permanent press and permethrin treatments.

PHASE I: Develop a proof of concept to incorporate durability, stretch, breathability, wicking, and comfort into a textile. Air permeation, stretch and recovery, flame resistance, moisture wicking, abrasion testing, and burst strength will be tested on the material IAW the ASTMS listed below in table 1.0. The detailed conditions of testing must be approved by the TPOC. At the end of Phase I, swatch sized samples will be delivered to the TPOC.Table 1.0 Phase 1 test methods and requirements will be uploaded with topic

PHASE II: The full scale manufacturing process must be demonstrated in Phase II. Further improvements on the textile properties are also the objectives of this phase of research, as needed.Full capability to sew into a garment must be demonstrated, seaming issues must be overcome. Continued testing on the scaled textile, as detailed in Phase I, will be conducted to ensure no loss in performance during scaled up production. This phase will demonstrate textile uniformity across the width and length of the production

PHASE III: The novel textile developed in this work with the aforementioned properties would have applications far beyond the standard issue uniforms, and could apply to improve a host of technologies, including equipment, CBRNe garments, and temporary structures such as tents. Use of the textile outside of direct military applications include; first responders, outdoor clothing and equipment, sports clothing, etc.
