INTRODUCTION
Methods D629-59 T, Quantitative Analysis of Textiles, were discontinued in 1969 because the
responsible subcommittee failed to recommend their adoption as a standard after several years of
publication as a tentative. The subcommittee action was based on the members’ knowledge that the
standard did not include several fiber types introduced to the textile trade after the method was
published, and that the techniques required for their identification were lacking in the text, allowing
it to become out of date. The procedures included in the text, however, are believed to be reliable for
the fiber types named and the techniques described are currently being used in the trade and are
referenced by other standards sponsored by Committee D-13 onTextiles. Reinstatement as a standard
using the previously assigned number was requested since the listed procedures were reliable and the
text considered to be the best available, though not all inclusive. Extensive editorial changes were
made in various sections in 1972, and the methods were reinstated as D629-72. Editorial changes
have again been made throughout the text, and statements on precision and bias and suitability for
acceptance testing have been added.
The text of Methods D629-59 T was published by the American Association of Textile Chemists
and Colorists in that society’sTechnical Manual as “Test Method20A-1959” issued in the years 1959
through 1974. The AATCC Method was revised completely in 1975 and since published as “Test
Method20A-1975.”
