Researchers had noted the release of formaldehyde by chemically treated fabric under prolonged hot, humid conditions (85,86). The American Association of Textile Chemists and Colorists (AATCC) Test Method 112 (87), or the sealed-jar test, developed in the United States and used extensively for 25 years, measures the formaldehyde release as a vapor from fabric stored over water in a sealed jar for 20 hours at 49°C. The method can also be carried out for 4 hours at 65°C. Results from this test have been used to eliminate less stable finishes.

The agitation studies for PET depolymerization were performed in the Atlas Launder-ometer. The Launder-ometer is a device for rotating closed containers in a thermostatically controlled water bath. The procedure used in these experiments was adapted from an American Association of Textile Chemists and Colorists (AATCC) standard test method. The 5% sodium hydroxide solution (250 mL) was preheated to 80°C in a 1-pint stainless steel jar. The catalysts were added in the following amounts in separate experiments TOMAC (0.04 g, 0.0001 mol) TOMAB (0.045 g, 0.0001 mol) and HTMAB (0.045 g, 0.0001 mol). The PET fiber specimens (1.98 g, 0.01 mol) were placed in the containers along with ten -in. stainless steel balls to aid in the agitation process. The jars were sealed in the Launder-ometer, whose bath was at the desired temperature (80°C). The machine was allowed to run for the allowed treatment times (i.e., 30, 60, 90, 150, and 240 min) at 42 rpm. Upon decanting, any residual fibers...

AMERICAN ASSOCIATION OF TEXTILE CHEMISTS AND COLORISTS (AATCC). Founded in 1921. It has over 6500 members. A technical and scientific society of textile chemists and colorists in textile and related industries using colorants and chemical finishes. It is the authority for test methods. It is located at PO Box 12215, Research Triangle Park, NC 27709. http //www.aatcc.org/... 

Dyes are catalogued and grouped under a set of rules established by the Colour Index committee, consisting of representatives from the Society of Dyers and Colourists (SDC), Bradford, England, and the American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC. Table 13.2 shows how over 9000 dyes are enumerated in the current Index.9 The Colour Index, now in its fourth edition, is updated periodically with newly released information and is available in book form and on CD-ROM. Volumes 1 to 3, published in 1971, contain the C. I. name and number, chemical class, fastness properties, hue indication, application, and usage. Volume 4, also published in 1971,... 

There are other minor nonequivalencies of ISO test procedures compared to ASTM standards, but for color difference the ISO Test Procedure No. 105 is unique. Those who use Colour Measurement Committee (CMC) procedures—particularly CMC 2 1 Lightness to Color ratio—claim that it facilitates a uniform description for acceptability decisions that is better than any other system in existence. These equations permit the use of a single number tolerance, DEcmc, in a nearly uniform color space. The CMC formula is a modification to the perceptibility CIELAB formula. It is fully described elsewhere in this book, but it deserves some brief notice here because, after all, it is an ISO procedure. The CMC developed the basic British Standard No. 6923, Calculation of Small Color Differences. Soon afterward, in 1989, the American Association of Textile Chemists and Colorists (AATCC) adopted AATCC Test Method 173, CMC Calculation of Small Color Differences for Acceptability. Ford Motor Company indicated a preference for using CMC 2 1 ratio color difference for plastics weathering data for plastics interior trim materials. 

Fabric. The fabric used in this work was a plain weave, 80 X 80 cotton print cloth weighing about 100 g/m2 (Testfabrics, No. 400). The fabric was twice laundered and dried according to the American Association of Textile Chemists and Colorists (AATCC) Test Method No. 124-1978.

The disadvantages of quantitative methods are that they are time-consmning, expensive, and they have not been assessed (with the exception of the American Association of Textile Chemists and Colorists (AATCC)-IOO method) for interlaboratory correlation of test results. Three quantitative methods are currently being nsed for determining... 

In this section, the production of PP nanofibres containing silver nanoparticles using the above technique, together with their characterisations using X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis are presented. Additionally, the antibacterial properties of nanofibres are evaluated using the quantitative American Association of Textile Chemists and Colorists (AATCC) 100 test. The inclusion of nanosilver into polymers to form a nanocomposite has been demonstrated to have a profound effect on the crystallisation of the polymer, which in turn affects the properties of nanofibres, including their antibacterial properties. 

The American Association of Textile Chemists and Colorists (AATCC) Test Method 100-1993 was used to determine the biocidal properties of the fabrics against the bacteria and fungi tested. The initial bacterial or fungal inoculum used varied between 1x10 to 4x10 colony formii units (cfix)/sample. These tests were carried out by independent laboratories AminoLab Laboratory Services, Weizmaim Industrial Park, Nes Ziona 79400, Israel, and Hy Laboratories Ltd., Park Tamar, Rehovot 76325, Israel.
