IFAI Specialty Fabrics Expo and Advanced Textiles Conference & Trade Show
AATCC is sponsoring the Functional Finishes and Coatings for Performance Textiles session as part of the educational offerings at IFAI Specialty Fabrics Expo and Advanced Textiles Conference & Trade Show. This session, moderated by Dr. Seshadri Ramkumar, Texas Tech University, will be held from 9:00 a.m. to 12:00 p.m. on Thursday, October 24. The program will focus on functional finishes and coatings that add value to products by enhancing fabric functionality and performance. Test methods used to evaluate these performance attributes as a means of assuring product quality will also be discussed.
The program agenda is as follows:
9:00 a.m. Welcome and Opening Remarks
Peter J. Hauser, North Carolina State University, AATCC President
Seshadri Ramkumar, Texas Tech University, Chair, AATCC Materials Interest Group
9:10 a.m. Enhancing Fabric Properties with Atmospheric Pressure Plasma, Peter J. Hauser,
North Carolina State University
This presentation addresses the advantages of atmospheric pressure plasma to modify fabric surface properties. The various forms of atmospheric pressure plasma (corona discharge, dielectric barrier discharge, atmospheric pressure glow discharge) are explained and compared. Several examples of durable surface modifications are given and the viability of atmospheric pressure plasma as a commercial textile process is discussed.
9:40 a.m. New Orientation in Atmospheric Plasma Research for New Products, Seshadri
Ramkumar, Texas Tech University
Environmentally processing has become an important task in the technical textiles field. Plasma, which is ionic state of matter, is explored these days to impart specialty properties to industrial fabrics. This presentation will outline recent research in the use of atmospheric pressure plasma in developing breathable barrier fabrics. Recent research activity shows that new functionality can be imparted to barrier fabrics at industrial scale without comprising important mechanical properties. This effort has opened-up new products for safety textiles and will be featured in this talk.
10:10 a.m. Surface Modification on Hydrophobic Surfaces using Protein Deposition, Carlos Salas,
North Carolina State University
Controlling the wettability of hydrophobic surfaces is very important in functional textiles that are in contact with fluids. In this work a new approach for surface modification to enhance the wettability of hydrophobic polypropylene (PP) fibers is proposed by physical adsorption of soybean proteins (glycinin, ß-conglycinin, soy flour and soy isolate). We establish that pre-treatment of PP with a cationic surfactant, dioctadecyldimethylammonium bromide (DODA), strongly enhances protein deposition, as confirmed by a significant improvement in water wettability (change in contact angle from approx. 120° to completely wettable surfaces). Furthermore, the results from wicking tests indicate that hydrophobic PP nonwovens absorb a significant amount of water after protein treatment, i.e., PP-modified fiber mats become completely hydrophilic.
10:40 a.m. Break
11:00 a.m. Fiber Surface Modification and Control: State of the Art and Future Prospect,
Thomas Theyson, TensTech, Inc.
Surface modification of existing natural or synthetic fibers is the most efficient way to generate fibers and fabrics with specific new or innovative performance properties. This presentation will review the existing approaches to surface modification, review the types of performance properties that have been achieved using the current technologies and discuss emerging technologies that may have a significant impact on the performance properties that can be generated in the future.
11:30 a.m. Moisture Management, Water Repellency, and Water Proofness: A Discussion of
Current Testing Methods, John Crocker, SDL Atlas
With today’s Apparel Industry focus on “performance”, an incredible number of products are being developed to improve the consumer’s comfort, whether that is through moisture management, water repellency, or water proofing. Due to the interest by the industry, standards organizations and equipment manufacturers have strived to develop new devices and testing methods in order to accurately quantify how the products behave. This presentation will review devices and methods, both new and established, currently used by the industry for the promotions and testing of Performance Textiles and recommend actions you need to take now.
