The State of the Industry - a North American perspective
William C. Smith, Principal, Industrial Textile Associates, USA
How are we doing? Not an easy question to answer as we begin to climb out of a major recession. Some segments are doing well, others are hurting. Much depends on where you are in the value chain. While fabricators and end use sellers may be doing well, fabric, chemical, and fiber producers may not as much comes from off-shore. The world has "changed in a flash" and if you haven't changed with it, you may be too late, or, at best, at least a year behind. Indications are it will be a long, slow, and painful recovery until the economy improves, the consumer regains jobs and confidence, and begins buying and spending again at pre-recession levels. But we are confident of recovery, perhaps a changed industry, but a strong, viable one.

Accepting the Challenge of Textile-based High Tech Products: Designing for Function
Melinda E. Wales, PhD, Reactive Surfaces, Ltd., USA
Biologically-derived additives offer a new, “green” approach for functionalizing textiles. Functionality is the most recent essential advancement in coatings technology that adds to the traditional role of a textile system. Natural biomaterials, such as enzymes or peptides, represent the next generation of additives that offer novel functional possibilities. Once properly identified, harvested and stabilized or mimicked, natural materials are available to provide functional additives which are non-persistent, non-toxic, renewable, and can be bioengineered for optimization. Advancing our understanding of these new biomaterials for functional textiles is driving the research efforts to push the limits and capabilities of these additives.

Advanced Textile Coatings Based On Sol-Gel And Plasma Technologies
Llorenç Bautista Pérez, Leitat, Departament de R&D, Spain
This paper will cover the research and development of new multifunctional textile products based on environmentally friendly emergent technologies like plasma and sol-gel and the optimum detergency products to maintain these functionalities.
Plasma technology has been applied to different textiles by surface activation, plasma pretreatments, superficial grafting induced by plasma, plasma enhanced chemical vapor deposition (PECVD) and plasma fixation methods. Sol-gel technology has been applied to textiles by the deposition of xerogel films based on: silicon dioxide or titanium dioxide, sols doped with nanomaterials or functional molecules, functionalization of previously deposited xerogels. Combinations of sol-gel and plasma technology have also been studied.
Practical, Low-Cost, Production Finishing of Textiles using High Power, Atmospheric Pressure Plasma Technology
Gary S. Selwyn, Chief Technical Officer, APJeT, Inc. , Santa Fe, NM USA
This talk emphasizes the practicality, green component and low cost of plasma finishing and coating of textiles, using newly-developed plasma processing equipment. Various types of atmospheric plasma will be shown, illustrating the importance of high-power, yet low-temperature plasma for practical, production-worthy finishing of textiles. The use of plasma to produce different surface states for various, desired textile attributes will be discussed, along with operational cost estimates to illustrate how plasma finishing of textiles can not only be cost-competitive with traditional padding methods, but also in many cases, can cost less to operate. Plasma provides an environmentally-sound, and energy-efficient approach to textile finishing. A full-scale production machine that uses 2 meter-wide electrodes and which operates at 10KW will be shown, along with the product-differentiating, unique end-user attributes this technology provides.
Reactive Surface Treatment For Improved Multi-Functional Textiles
John Almond, Business Development Director, Ålexium International Group, Australia
Technology initially developed in a US Department of Defense (DoD) Laboratory through a research and development program on chemical and biological warfare defense and infection control has potential for many other technical applications. The low energy process takes only seconds and allows for the surface modification and simultaneous attachment of multiple functions onto a wide range of surfaces/substrates, resulting in improved textiles that are machine washable, self-extinguishing in a fire, super waterproof, oil resistant and chemical agent reactive. With the establishment of a new plant in the United States, work is actively progressing to develop new applications for the technology where new or improved functionality is required for the next generation "intelligent" high performance products.

Prepregging For Composites - An Opportunity for Coaters and Laminators
Francis A Woodruff, Chairman, Web Processing (M/C) Limited, UK
The production of carbon and other high tech fiber based composites formerly required large, expensive, and environmentally polluting equipment for prepregging, a necessary step of combining the fibers in a matrix of resins prior to curing. Most new prepregging plants use small, relatively inexpensive, solvent free, low temperature curing, hot melt resins with no environmental pollution and low energy utilization. Success requires having the whole package comprising the right fibers, construction of fabric, the right resin formulations and the right resin to fiber ratios. The paper will also seek to explain many of the options and alternatives appropriate to the industry, for today and the future.

Wearable Embedded Optical Chemical Sensors
Professor Aleksandra Lobnik, University of Maribor, Faculty of Mechanical Engineering, Centre of Sensor Technology, Slovenia
Wearable optical chemical sensors can be used to provide valuable information about the wearer’s health and/or monitoring wearer’s surrounding environment, detecting safety concerns and threats, during wearer’s daily routine within their natural environment. The “chip on a textile”, an integrated chip capable of data analyzing, would enable early detection as well as providing simultaneously comfort and monitoring and non-invasive measurements. Wearable technologies should be soft, flexible, and washable to meet the expectations of normal clothing. The optical sensors can be used as wearable technology since they can be embedded into textile structures using conventional processes as well as coatings and laminates by incorporation of embedded optical chemical fiber sensors. Application technologies lead to an integrated optical activity in a commercial textile which can be used as a sensor.
