Evolution of Chemical Applicators for Textiles – a Historical Review of Chasing Water

Preston Aldridge, Vice President, FTA, Inc.

Our industry began in fields out in the open when Man was mostly Nomadic and washers were rivers. With the change to a more stationary lifestyle, the location moved to the yards, porches, kitchens, and laundries of homesteaders. The General Store needed a supply chain thus creating large laundries followed by large mills for larger runs of fabric. As the world became more global, the larger mills moved to faraway places and we returned to smaller ones. Laundries for garments once again were in vogue and only recently have lost favor due to pollution and excess water consumption. Enter laser engraving of fabric, ozone gas treatment for preparation and plasma for finishing. Now water is gone. Enter nonwovens and applicators are gone with the placement of particles in the substrate which perform the roll of chemistry. What an exciting time to live!

Prior, Alexander spent twelve years ending in 1999 at the Institute of Textile Technology located in Charlottesville, Virginia, where he was Director of Chemical, Energy, and Environmental programs. He was responsible for applied research, monitoring of global technology development, and industry consulting and expanded ITT’s focus on environmental & energy programs. Alexander was also involved in the creation and management of an industry-wide project between the textile industry and the US Department of Energy (DOE) National Laboratories called the

AMTEX Partnership and was instrumental in the development and management of a large environmental project called the Textile Resource Conservation Project which included 40 participating industrial companies and 8 National Laboratories. Alexander managed all facets of the project including participation of 115 industry representatives working with 29 National Laboratory scientists. Alexander also taught in the Graduate program and participated extensively in ITT’s continuing education seminars.

Prior to joining ITT, Alexander worked with Milliken & Company in manufacturing and technical management.

Value-Added Finishing in the USA, Strategies Enabling Innovation and Entrepreneurial Business Development

Don Alexander, President, Anovotek, LLC

Textile products containing performance attributes offer great opportunity in the USA market but typically require global supply chains, large volume commitments and long lead times. Textile fabric finishing in the USA is viable, however finding cutting and sewing capacity in the USA is extremely difficult. Protecting IP when finishing fabrics offshore is nearly impossible despite the efforts being made through global trade agreements. This presentation will detail an innovative, entrepreneurial approach for value-added finishing in the USA. Utilizing both domestic and global supply chains for products while doing value added finishing in the USA coupled with direct-to-consumer sales will be discussed. A case study of a current manufacturing operation utilizing this approach and will be presented including processing options, process control and process performance data. The success of a performance apparel brand using this approach will also be discussed.

About

Roger L. Barker is a Professor in the Department of Textile Engineering, Chemistry and Science at North Carolina State University and Director of TPACC.  He is internationally recognized for his work in the field of thermal protective clothing and comfort and heat stress in clothing systems.  Barker has published many technical papers on the subject of the effects of intense heat exposures on fabric materials including exposures to flash fire, molten metal, hot surface contact and radiant energy.  He was Chairman of the 1984 ASTM International Symposium on the Performance of Protective Clothing.  He is an active participant in several committees of the National Fire Protection Association, which are involved in the development of standards for the performance of protective clothing.  Barker holds B. S. and M. S. Degrees in physics from the University of Tennessee and a Ph.D., in Textile and Polymer Science from Clemson University.  He has positions at Cornell and at Clemson Universities.  His industrial experience includes work as a physicist in spun bonded fabrics research.

Research

Thermal protective performance of textile fabrics and clothing, heat transfer mechanisms in intense heat exposures. Fabric and clothing flammability, materials response and testing methodologies.

Comfort properties of textile clothing and materials, heat and moisture transfer in textile structures, objective measurement of fabric hand.

Industrial analysis of thermal and mechanical properties of textile fabrics. Textile measurement technologies, instrumented manikins. Assessment of human sensory and physiological response to clothing comfort.

Evaluating Textiles with Performance Properties

Dr. Roger Barker, Director, Textile Protection and Comfort Center (TPACC)

The commercial success of technical fibers, fabrics and finishes depends on their performance in a variety of applications ranging from flame resistant garments to outdoor and sports products. We can evaluate technical textiles as individual components, but there is great value in testing them as whole systems. This presentation describes how a new generation instrumented manikins called Pyroman™, Radman™ and Comfortman™ and other advanced tests can be used, either separately or together, to demonstrate the performance of technical textiles for first responder and work wear in ways that were never before possible. It will describe case studies drawn from recent TPACC research projects that have developed advanced clothing prototypes for homeland security, firefighting and workplace applications. These studies have shown the value of using a fully integrated product development approach supported by advanced product testing. Some have developed prototypes for protecting firefighters from extreme thermal or toxic environments, including wildland fire and exposure to contaminates and smoke. Others have developed clothing systems for comfort by combining advances in materials technology with garment design. All confirm the value of developing textile products using scientifically based measures of their performance properties.
