NYC wants to help manufacturers developing, learn about, and adopt innovative advanced technologies. Vartest has won a 2019 Advanced Material Grant from the Cornell Center for Materials Research, Invest-NY, and Ops21 to develop methods to analyze wool and cashmere fibers — Vartest will use this grant to standardize methods to detect and report the make-up and quality of important industrial materials.

The battle against counterfeit goods is well known in the luxury industry. As production shifts overseas, companies have less control over their supply chains, leading to the rise of fakes. With the total global trade of counterfeit goods reaching nearly half a trillion dollars a year, no industry is immune to counterfeiting and IP infringement.
However, in the personal protective equipment (PPE) arena, counterfeiting poses more than just a branding and business challenge. It represents a human life safety concern. For example, high-visibility safety apparel (HVSA) is critical to workers in highway, roadway, and traffic zones. In such cases, HVSA helps alert vehicle drivers to the presence of workers in low-light, low visibility environments. Given the hazards of working in high-traffic areas, there is a huge safety risk for workers who wear HVSA garments that are non-compliant and fake.
One keystone document used to assess the integrity of HVSA garments is ANSI/ISEA 107: The American National Standard for High-Visibility Safety Apparel and Accessories. This standard provides the minimum performance requirements for high-visibility garments, as well as performance class guidelines for HVSA garments worn in different work zones.
Following and understanding these guidelines will be the first step to combating counterfeit, and non-compliant HVSA garments. Many items in the market fail performance requirements. Yet they are still sold and improperly marketed since qualities such as retroreflectivity are difficult to examine visually. The following three part summary will aid your understanding of the performance standard.
Fluorescent Background Material: Under normal daylight, the fluorescent background—for example, fluorescent yellow—provides adequate contrast against a background to improve visibility.
Retroreflective Tape: This component plays a huge role in nighttime visibility. As its name suggests, retroreflective materials can bounce light back to its source. This quality ensures that the wearer is noticeable in all postures and orientations.
Design: Different garment types must contain a “minimum area of visible materials.” For example, an HVSA garment used for off-road zones constitutes a Class 1 garment. This classification requires a minimum area of 0.14 sq. m of fluorescent background material and 0.10 sq. m of retroreflective tape. Design features such as pocketing and logos affect the proportion of visible tape and background material. Thus, one must consider style variations when evaluating HVSA compliance.
We leverage our comprehensive expertise in HVSA garment evaluation to help keep fake products off the market, ensure worker safety, and educate consumers. In May, Vartest CEO Adam Varley presented on counterfeit textiles at the Fashion Institute of Technology’s “Forum on Sustainable Labor Practices” AATCC Student Chapter event. A summary of his talk is featured in Applied DNA Science’s June newsletter.

Vartest is one of the few labs that are able to deal with both the textile technology and organic chemistry aspects of permethrin testing.
Permethrin is the most widely used insect repellent against mosquitoes, ticks, cockroaches, and other pest insects. It is typically applied as a finish to both textile piece goods and finished apparel.

Using gas chromatography/mass spectrometry (GC/MS) based industry standard methods and military specifications, Vartest is able to report the amount of permethrin present on a garment both as a percentage on weight of fabric (OWF) and as a mass per unit area (grams per square meter or ounces per square yard).
Vartest is also able to assess the amount of permethrin present on a garment after refurbishment, using both diagnostic and industrial wash formulas as well as dry cleaning.

Vartest hosted Dr. Preeti Arya and her Fashion Institute of Technology (FIT) Textile Development and Marketing class. Students watched a PowerPoint focusing on the difference between Product Performance Specifications and Test Methods.
The students toured the lab seeing ASTM, AATCC, ISO, GB, ACT, BIFMA and Federal Standard 191 test methods for testing fiber, yarn, fabric (both coated and uncoated), used in apparel, aerospace, medical, military, couture, upholstery and active sportswear end uses. Specialty testing markets like HVSA (High Visibility Safety Apparel) were reviewed in detail.
Vartest is glad to have built a relationship with the textile and apparel quality assurance and compliance executives of the future and continues to work with both FIT and its students.
Fascinated by what a ‘fasciated’ yarn is? Vartest recently published a whitepaper on the AATCC website to showcase our advanced capabilities in classifying yarn structures created by recent textile technologies such as Vortex spinning. This work complements our expertise in identifying open end, ring spun, and air jet yarn types.

We recently had a visit to the Vartest lab from Flora Lichtman of Every Little Thing in Brooklyn, NY to discuss textile testing for care label symbols. What resulted is an interesting and informative introduction to the care symbols used in garment labels around the world.
Of special note are comments from John Langdon of Drexel University in Philadelphia (The inspiration for the Robert Langdon character in Dan Brown’s books) on the challenge of intuitively understanding the meaning behind the current symbols. We also get insight from Ginetex, the International Association for Textile Care Labelling, on the origin of the symbols. Ginetex shared that symbol comprehension is surprisingly low – 70-80% of consumers don’t know what 3 of the 5 main care symbols mean.

Dynamic Seam Fatigue (ASTM D4033) assesses the ability of a fabric to be sewn effectively for use on upholstery fabric. The cyclic impact of a weighted wheel over a fabric-covered foam block simulates repetitive stress onto a seat cushion. Just think: how many times this week have you crashed onto your couch after a long work day?
Similar to assessing a portion of your most comfortable reclining chair, a diner booth, or newly upholstered car seat, Dynamic Seam Fatigue testing measures resistance to yarn slippage. This method is used across a variety of markets—contract & residential upholstery, home, hospitality, and automotive textiles to name a few.
How it works:
The Dynamic Seam Fatigue tester plunges a rubber-faced wheel 7,000 times onto a standard 7-SPI (stitch per inch) upholstery seam. Specimens are sewn in the warp to warp, filling to filling, and warp to filling direction. If after 7,000 cycles, the seams demonstrate no failure, the fabric is determined to have passed the criteria established by ASTM (American Society of Testing and Materials) and BIFMA (Business and Institutional Furniture Manufacturers Association). ASTM D4033-92 is used, modified by BIFMA X 5.4-2012 Seating Durability Test as the standard test method.
See the machine in action below!
How we can help:
Along with the fabric ratings, Vartest provides photographs of any failing specimens so that the Dynamic Fatigue test report can provide effective communication with the supply chain.
We are happy to share that Adam Varley, co-founder of Vartest Laboratories in NYC has been interviewed and cited in the newly released book by Deanne Clark-Esposito, entitled, “A Practical Guide to Fashion Law and Compliance“. Adam’s comments are part of a Q&A in “Chapter 5 – Flammability Testing and issues specific to children’s products”.
