Introducing, the "Grex," R. O'BRIEN. (U. S. D. A.). (Jour. Home Econ., 35
(1943), No. 10, pp. 637).--This article defines the Grex and explains' briefly what
it is and why it is being introduced. It is a new word coined to name the unit
upon which is based the new proposed system for numbering yarns. The name
is derived from "grams per 10 kilometers" (GRams pEr X), and the Grex would
be the weight in grams of a 10-km. length (10,000 m.) of yarn. "Some of its
advantages are that it could be used in numbering all kinds of yarns (eliminating
the many confusing systems now in use) and that it is based on the metric system
which is much easier to use in calculations. It is a direct system, giving higher
yarn numbers for heavier yarns."
Compression meter for evaluating the compressibility and resilience of fabrics,
E. C, DREBY (Amer. Dyestuff Rptr., 33 (1944), No. 10, pp. 199-204, illus. 2).The
compression meter, described as to construction, operation, and calibration and
illustrated by photograph and diagram, was devised for evaluating the compressibility
of soft-finished, light-weight fabrics under pressures of 0.05-0.50 lb./in? It
utilizes the combined pressures of a liquid column and air under pressure, this being
transmitted to the test specimen through a very thin rubber membrane. Thus low
pressures are distributed relatively uniformly over the test area. The results of
compression meter measurements are presented for a series of cotton percales,
100 X 56 cotton fabrics, and spun rayon fabrics. A comparison of these results
with the. hand, or feel, of the fabrics as judged by a group of textile experts
indicated that the compressibility affects directly the feeling of "thickness." By
combined results of measurements of compressibility and flexibility a measure of
"fullness" was obtained. The comparison meter may also be used to evaluate
Thermal properties of moist fabrics, C. W. HOCK, A. M. SOOKNE, and M.
HAmRu (Amer. Dyestuff Rptr., 33 (1944), No. 10, pp. 206-219, illus. 21).-"The
'chilling effect' or 'clamminess' which moist fabrics produce when in contact with
the body was evaluated by subjective tests, by measurement of the drop in temperature
which ensues when the moist fabrics are placed on an artificial 'skin'
surface, and by tests with a moisture-sensitive paper designed to measure the
extent of contact which the fabrics made with a surface. Using fabrics of various
fiber compositions and constructions, a good qualitative relation was found in
these tests. Fabrics which produced considerable chilling in subjective tests were
found to make good contact, and to cause a substantial drop in skin temperature.
Conversely, fabrics which caused little or no clamminess made poor contact, and
the accompanying drop in temperature was relatively small. The results of these
experiments show clearly the progressive improvement of the fabrics with respect
to chilling as their wool content is increased, and also the superiority of certain
types of construction which minimize the extent of contact of the fabrics with
The analysis of 33 qualities of unbleached muslin, G. B. FRANKENBERG and
M. B. HAYS. (U. S. D. A.). (Jour. Home Econ., 34 (1942), No. 10, pp. 737-741,
ills. 2).-The-33 materials used in this study were obtained as representative
qualities from all large manufacturers and included five classes in which there
were grades of muslin suitable for a variety of household purposes. These
muslins were tested in accordance with standard methods of the American Society
for Testing Materials, except that sizing was removed by a modified procedure
previously used by G. R. White,1 and involving immersion of the samples in carbon
tetrachloride for 2 hr. at room temperature, drying, rinsing in boiling water, immersion
in an enzyme solution for 1 hr., and finally boiling in distilled water for two
