AATCC Recognizes Varley, Greeson With TCR Service Award

     RESEARCH TRIANGLE PARK, N.C., USA, April 10, 2014— H. Kenneth Greeson of Cotton Incorporated and Adam R. Varley of Vartest Laboratories Inc. were honored by the AATCC Technical Committee on Research (TCR) with the TCR Service Award in recognition of their achievements and service to AATCC. The award was presented at the 2014 AATCC International Conference in Asheville, NC, on April 3, 2014. Varley was recognized for his contribution toward the development of the Fiber ID Technical Supplement and for almost yearly additions or revisions to Test Methods TM 20 and TM 20A in an effort to make those the most complete test methods in the world. Greeson was recognized for his contribution toward the major revision of AATCC Test Method 97 (Extractable Content of Textiles) for the 2014 AATCC Technical Manual. Greeson attended North Carolina State University (NCSU) and graduated with a Bachelor of Science in textile chemistry. His current position at Cotton Incorporated is Manager, Textile Chemistry Research, in the Textile Chemistry Research department. His primary responsibilities include research and development in the field of fabric finishing, including areas such as wrinkle resistance, moisture management, repellency, flame retardancy, and abrasion resistance. His responsibilities also include management of the Finishing Research Laboratory.

     Varley is Technical Director and Co-Founder of Vartest Laboratories Inc. He attended the Fashion Institute of Technology from 1978 to 1980, working toward an Associate Degree in Textile Technology. In 1987 he graduated with a BA in Computer Science and Business Management from New York University and in 2001 he received a Master of Textiles, Textile Chemistry and Apparel Management, from North Carolina State University. He has been a member of AATCC since 1978 and has been active in several research committees, especially in RA24, Fiber Analysis Test Methods, where he has served as chair or acting chair and is currently chair. Outside of AATCC, Varley has served on ASTM Committee D13 for textiles, two subcommittees responsible for test method and specification development, and on the US Technical Advisory Group (TAG) for ISO/TC38-Textiles for Working Group 22, Chemical Test Methods.

     The Award: The Technical Committee on Research Service (TCR) Award was established in 2008 to recognize those members who have contributed greatly to the AATCC organization in a technical capacity. Senior members of the Association with at least five years of continuous membership in AATCC, who have contributed outstanding technical service to the Association through activity in a research committee, are eligible. Selection is by unanimous choice of the TCR Service Award Committee, composed of the current Chair of Technical Committee on Research, Vice Chair of TCR, Chair of the Executive Committee on Research (ECR) and the Secretary of TCR. The Award consists of a plaque and an honorarium, presented at the International Conference.

     About AATCC: AATCC, the Association of Textile, Apparel & Materials Professionals, is the world’s leading not-for-profit association serving textile professionals since 1921. AATCC, headquartered in Research Triangle Park, N.C., USA, provides test method development, quality control materials, and professional networking for members in about 60 countries throughout the world.

Vartest In The News

Vartest Laboratories, Inc. recently appeared on ABC’s 20/20 in a special titled “20/20 True Confessions: Dirty Little Secrets from the Dry Cleaners”. In the segment, 20/20 sampled 10 drycleaners in Manhattan with identical garments containing mustard, wine, and nail polish stains. Vartest Laboratories was chosen to perform a Spectrophotometric Analysis of the stains on the returned garments to discover just how many of the selected drycleaners were able to remove the stains the best.

The ABC special as well as the results of the investigation can be found here: 20/20 True Confessions

Vartest Accredited to Test For Phthalates Under CPSIA:

Vartest has obtained A2LA accreditation to test for phthalates under the Consumer Product and Safety Improvement Act (CPSIA). This test (designation CPSC-CH-C1001-09.3) provides an excellent complement to Vartest’s lead and heavy metal detection testing services, allowing our laboratory to ensure full safety compliance for a range of materials and products.

Three-dimensional model of a Di (2-ethylhexyl) phthalate, or DEHP, one of the most common phthalates in use.

 

Phthalates are compounds of phthalic acid widely used as plasticizers, chemical compounds which increase the strength and malleability of plastics. Found in or on the majority of plastic or polymeric products worldwide, including toys, textiles, garments, and upholstery, phthalates and plasticizers in general are produced and used by the millions of tons per annum. However, phthalates’ weak chemical bond to the plastics in which they are used (specifically, the lack of a covalent bond) allows them to be relatively easily released into the environment when the plastics age. This process has been associated with certain detrimental effects to the environment, resulting in phthalates’ regulation under CPSIA as of February 10, 2009.

Vartest tests for phthalates using the Standard Operating Procedure supplementary to CPSC-CH-1001-09.3, dissolving the sample in a solution of HPLC-grade tetrahydrofuran (THF), precipitating sample polymers with HPLC-grade hexanes, and filtering the solution through a .45μm polytetrafluoroethylene (PTFE) filter. The filtered solution is then subjected to gas chromatography and mass spectrometry (GCMS) to isolate and identify the resultant phthalates. Samples are monitored using both full scan mode and selected ion monitoring (SIM), and our machinery runs a quality control sample each day. Products tested include fabric adhesives, coatings, print applications, children’s products, plastic components of various garments, and other end use items.

Vartest GCMS Equipment
