Lecture was presented at Techtextil North America Symposium 2008

I. Introduction

The United States Marine Corps and the U.S. Army have taken the initiative to develop state-of-the-art fire retardant nonwoven composite fabric technology for use mainly in Combat Utility Uniforms (CUUs) and coveralls. This effort is being conducted via Small Business Innovative Research (SBIR) contracts awarded to Nanosyntex, a Tennessee-based company. Essentially, SBIRs are very competitive and offer the perfect medium in which to conduct what may be termed "high-risk technology." There are generally two phases that are funded by the Department of Defense: Phase I allows for "proof-of-concept" to be conducted within 9 months. If successful, Phase II allows for effort toward concentration of bringing the technology to a rapid fruition within 2.5 years. In rare situations, a Phase III effort is allowed toward manufacturing; however, joint partners are necessary to help in receiving matching funding. It must be understood that commercialization of product is critical toward acceptance of each phase. For additional SBIR information, visit: www.acq.osd.mil/sadbu/sbir/ .

This briefing discusses their effort toward the development of multi-layered, hydro-entangled nonwoven composite fabrics; properties of those developed fabrics as related to current woven military base fabrics; commercial applications; and current Phase II development and other related aspects including fire-retardant (FR) fabrics for military application. These durable nonwoven fabrics can be designed to integrate blends of various fibrous webs that impart water absorbency or repellency, fire and thermal resistance, antimicrobial treatment, etc. These reinforced multi-layer nonwoven composite fabrics have been engineered to be lighter in weight, significantly more breathable, and superior in tear and breaking strength as opposed to the conventional woven uniform fabrics. Advanced research is being conducted to enhance the durability and wash resistance characteristics for military and outdoor applications. In addition, the possibility of incorporating FR fibers and additives, barrier materials and nano-fiber based technologies within the nonwoven composite structure will be explored.

II. Purpose

To review U.S. Marine Corps and U.S. Army SBIR Phase I and update Phase II contract for development of novelty nonwoven fabric for military applications.

III. Goals:

The primary goal of SBIR is to develop and incorporate enhanced nonwoven fabrics for military-type uniforms applications. Nanosyntex stressed the development of a composite, uniform nonwoven that possesses high strength, softness, improved abrasion resistance, printability and other related characteristics.   

IV. Primary Contractor:

Nanosyntex

V. Description

The objective of SBIR projects is to utilize the latest nonwovens, FR fibers and treatment technologies to enhance performance and reduce lifecycle costs for combat-type clothing. The concept includes development of lightweight composite material that offers high durability, high breaking and tearing strength, breathability, and cost reduction to replace current woven uniform material. Included is the design of a FR fabric mainly for military FR apparel application.
