AATCC: revised test method for antibacterial finishes on textile materials
One of the most commonly used test methods to measure antimicrobial activity on treated textiles is the AATCC TM100. This method, developed in the 1960’s by the American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, and updated periodically, has now been updated to more accurately capture the performance of today’s antimicrobials that have a smaller environmental impact. This revised method provides the industry with more consistent and uniform test results.
The revised AATCC TM100-2019 eliminates the variability on many of the critical steps that previously led to variability in test results, even on identical substrate. Coupled with other standard protocols, this method will allow for a much clearer prediction of real-world antimicrobial activity on a treated article. It will provide better repeatability within laboratories and more importantly, reproducibility between laboratories.
AATCC TM100-2019 is now available for purchase through the AATCC website and it will also be included in the AATCC 2020 Technical Manual released January 2020.
Labs can evaluate their performance on antibacterial test methods by participating in the AATCC Proficiency Testing Program. Registration for 2020 rounds will open by October 2019. The Antibacterial Module is distributed in April.

AATCC: new Technical Director
The American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, has announced Erika Simmons as the new Technical Director.
Simmons has been active with AATCC committees and educational programs throughout her career. She served on the AATCC Executive Committee on Research and as Secretary and Chair of RA63 – Water Resistance, Absorbency & Wetting Agent Evaluation. In addition, Simmons has provided instruction on moisture management at AATCC workshops.
Simmons has more than 20 years of experience in the testing labs of HanesBrands Inc., Winston Salem, NC/USA, providing leadership and training, developing solutions, and launching new programs. As compliance manager, she led projects in quality management to meet customer compliance requirements and government regulatory mandates. Previously, Simmons held the position of quality manager at Fruit of the Loom, Bowling Green, KY/USA, and process engineer at Milliken & Co., Spartanburg, SC/USA.
SDL: new General Manager of Americas and Europe
The supplier of textile testing solutions SDL Atlas LLC, Rock Hill, SC/USA, has announced that Brian Francois has joined the company as its General Manager of Americas and Europe. Francois came to SDL Atlas from the American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, where he was the Executive Vice President. Prior to that, he spent 25 years at Pulcra Chemicals GmbH, Geretsried/Germany, a supplier of specialty chemicals.
Francois is responsible for the SDL Atlas operations and staff in the USA and the UK, as well as the markets in the Americas and Europe.
AATCC: revised test methods and procedures available
The American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, has released the 2019 Mid-Year Supplement, including 16 revised standards and one new evaluation procedure approved since publication of the 2019 AATCC Technical Manual. Official designations and titles for all AATCC standards have been updated.
The new procedure is initial evaluation of electrical resistance of electronically-integrated textiles and/or for evaluation of these same textiles after some treatment (e.g. laundering, stretch, etc.) This is the first global standard for e-textiles.
The test methods and procedures revised since publication of the 2019 AATCC Technical Manual include test methods for laundering, soiling and electrostatic properties, among others.
These documents are available only as downloadable PDFs for 2019. The 2019 Mid-Year Supplement will be discontinued at the end of 2019 and all standards contained therein will appear in the 2020 AATCC Technical Manual.
AATCC: Patrick Gruber to receive Millson Award
The American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, has named Patrick R. Gruber as the recipient of the Henry E. Millson Award for Invention for developing a green chemistry-based continuous process for producing polylactic acid (PLA) fibers. The Millson Award recognizes inventions that are outstanding contributions to textile technology.
Large chemical companies had spent decades trying to find a renewable and environmentally safe raw material to make into plastic. Until Gruber’s discovery in 1989, no one had discovered out how to make PLA from plant starches with the right properties and inexpensively enough for large scale production. A new fermentation and distillation process enabled cheaper purification, better optical composition control, and significant yield increases over existing practice. The patented process enabled a single plant, using a flexible manufacturing system, to produce different PLA grades for multiple markets at low cost while adhering to environmentally sound practices.
Gruber is CEO and board member at Gevo Inc., Engelwood, CO/USA, specializing in converting carbohydrates into low carbon chemicals and fuels, lessening reliance on petrochemical sources. He began his career at Cargill Inc., Wayzata, MN/USA, in 1988, co-founded NatureWorks, LLC (formerly Cargill Dow, LLC) in 1997, and served as Vice President of Technology and Operations and Chief Technology Officer until 2005.
AATCC: Howard C. Malpass receives Olney Medal
The American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, has announced Howard C. Malpass as this year’s recipient of the AATCC Olney Medal Award. Malpass is being recognized for his work on the implementation of pre-reduced indigo and its beneficial impacts in the dyeing, manufacturing, and retail industries. The result of his work is a zero-discharge process. Malpass’s contributions have helped introduce a more cost-efficient, sustainable, and salubrious indigo dye process for suppliers, manufacturers, and retailers.
Established in 1944 in honor of Louis Atwell Olney, the founder and first president of AATCC, the Olney Medal recognizes outstanding achievement in textile or polymer chemistry or other fields of chemistry of major importance to textile science.
AATCC: international standard for resistance of e-textiles
The research committee RA111, Electronically-Integrated Textiles, of the American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, has approved its first evaluation procedure. AATCC EP13, Evaluation Procedure for Electrical Resistance of Electronically-Integrated Textiles, is one of the very first international standards for e-textiles.
The procedure provides detailed instructions for measuring resistance of e-textiles – a key indicator of functionality. It also includes guidance and calculations for determining change in resistance after laundering, stretch, or other treatment. The procedure can be performed on a variety of materials, including those with woven, knitted, printed, or stitched conductive elements. AATCC EP13 is suitable for component fabrics or complete e-textile products. It is designed to be performed in standard atmospheric conditions for textile testing and the apparatus can be purchased inexpensively from a variety of sources.
