    Evaluation of Army Battle Dress Uniform Fabric Containing an Electrically Conductive Network
    (2010-08-07) Charette, Christine DiSanto; Dr. Timothy Clapp, Committee Member; Dr. Trevor Little, Committee Member; Dr. Abdel-Fattah Seyam, Committee Chair
    Technology is being developed to add a conductive network to the Army Battle Dress Uniform (BDU). To embed the network within the BDU fabric, electronically conductive yarns are located at every ripstop location. To optimize conductivity, fabric construction had to be modified from MIL DTL 44436 requirements. The primary objective of this research was to determine how the addition of the electrically conductive network would change the comfort and durability properties of the BDU. To accomplish this, eleven fabrics of varying fabric constructions with and with and without the network were woven at the College of Textiles, NC State University. These fabrics were then evaluated for any changes in performance in the properties of breaking force and elongation, tearing strength, stiffness, thermal resistance, air permeability and abrasion resistance. The results from each of these tests were statistically analyzing using SAS JMP® software to reveal any property changes as a result of the fabric changes of yarn type, float length and location that were necessary to allow the addition of the network.

    Increasing the Cost Competitiveness of the US Textile Manufacturer through the Attenuation of Slasher and Sized Yarn Waste
    (2007-04-27) Eskew, David; Dr. Helmut Hergeth, Committee Member; Dr. Abdel-Fattah Seyam, Committee Chair; Dr. Pamela Banks-Lee, Committee Member
    Due to the changing markets for US Textile manufacturers, many manufacturers are running numerous styles as compared to in the past. Also, the longevity of these styles do not compare with past commodity products these same manufacturers used to produce. Set lengths continue to decrease in size as customers demand shorter, more specialized orders. The amount of waste created in the warp preparation processes, while in the past commodity business was considered acceptable, has become a significant factor in lost profits. This research works with slashing experts in the textile industry, from vendors and manufacturers, to investigate methods to reduce this inherent raw material waste in warp preparation. The areas of focus include: process engineering, and innovative controls, and new technology. The process engineering focus investigates reasonable methods and procedures used throughout the industry, in turn, developing a "best practices" summary for reduction of waste in smaller slashing lots. The "best practices" compilation covers all aspects of warping and sizing that create waste and suggests ways to reduce these wastes with little, if any, capital expenditures. The innovative controls focus explores available software programs and other accessories that may be available to aid in the reduction of waste. And finally, the investigation of new technology works directly with the vendors of warping and sizing machinery to focus on what products on the horizons are available to reduce this generated warp preparation waste for smaller lot sizes.
