Aramid polymers are manufactured for specific but diverse end uses and have nominal regains that vary in the range 1.5 to 7.0 %. The values listed in the table are the
commercial regains of fibers currently produced.
B
There is no commercial regain value for raw cotton in U.S. trade. The value specified in Rule 15 of the Egyptian sales contracts and in Rule 105 of the Liverpool sales
contract for Egyptian and Syrian cotton is 8.5. The value 8.5 is also used customarily for the cotton component of blends containing cotton in the process of performing
quantitative analysis.
C
Commercial Standard CS11-63, which is issued by the National Bureau of Standards, recommends these values to be used for cotton yarns by dyers and finishers.
D
These values are the official commercial moisture regains listed in British Standards Handbook 11, Methods of Test for Textiles, Section 1, 1963.
E
A moisture content of 12.0 %, which is equal to a moisture regain of 13.6 %, has been recommended for all wool yarns in Practice D2118. However, certain other regain
values are commonly used. Other values, which should perhaps be classified as commercial allowance values, are listed below for information only.
Woolen yarn 13.0
Woolen hand knitting yarn 11.1
Worsted yarn (dry spun) 15.0
Worsted yarn (oil spun) 13.0
F
For the commercial moisture contents of wools to which various specific commercial designations are applied, see Practice D2720.
G
Class III modacrylic fibers include such fibers as Verel modacrylic fiber. Class II includes such fibers as SEF modacrylic fiber. Class I modacrylic fibers includes all
other modacrylic fibers.
