HOLE SIZE DETERMINATION

The hole size is determined by measuring the hole void in both the course and wale directions and taking the average of the course and wale void dimensions; a minimum of ten voids shall be measured in each direction. The fabric should be laid flat and under no tension when measuring hole void.

DRY TIME PROCEDURES

4.4.1.3.1 Apparatus and materials. The following apparatus and materials shall be used:

a. Wringer (motor driven) (see 4.4.1.3.4.a).

b. Laboratory balance, accurate to 0.01 gram.

c. White AATCC Textile Blotting Paper, 25 x 25 centimeters (see 4.4.1.3.4.b).

d. Water, distilled.

e. 250-milliliter glass beaker.

4.4.1.3.2 Test specimens. The fabric samples and blotting paper should be conditioned at 65±2 percent RH and 70±2 °F for a minimum of 4 hours. Three (3) 2- by 2-inch test specimens shall be tested per sample.

4.4.1.3.3 Drying time test procedure. The following drying time test procedure shall be followed:

a. Run test in standard conditions: 65±2 percent RH and 70±2 °F.

b. Weigh the conditioned specimen using a laboratory balance accurate to 0.01 gram.

c. Place 100 milliliters of distilled water into a 250-milliliter glass beaker.

d. Submerge the specimen in the beaker of water for 30 minutes. Make certain that the specimen is completely submerged to insure complete wetting.

e. Remove the specimen and sandwich it between two pieces of unused blotting paper. Pass the sandwich through the wringer with a dead weight load of 27.7±0.5 kilograms.

f. Immediately place specimen on the balance with top door of the balance open, side doors closed and record wet weight either to the nearest 0.01 or 0.1 gram. (Degree of dryness shall be determined by the user.) Manually monitor weight at set intervals until dry or use an automated balance with capability to weigh specimen until dry (see 4.4.1.3.4.c). Record time to dry.

g. Repeat for remaining specimens. Average the 3 specimens.

4.4.1.3.4 Drying time test notes.

a. Wringer (motor driven): see AATCC TM70, footnote 11.2.

b. Blotting paper: see AATCC TM70, footnote 11.3.

c. Balance: Suitable Automation Software, PerkinElmer Inc., http://www.perkinelmer.com/.

MOISTURE REGAIN CALCULATION

Use the commercial moisture regain values (CMR) from ASTM D 1909 of the fibers used in the yarn blend and calculate using the following formula:

Total Commercial Moisture Regain = CMR Fiber 1 * Fiber 1 blend percentage + CMR Fiber 2 * Fiber 2 blend percentage + CMR Fiber 3 * Fiber 3 blend percentage…..

Example 78/22 Modacrylic/rayon fabric 0.4% * 78% modacrylic + 11% * 22% rayon = 2.7% commercial moisture regain Where 0.4% is the commercial moisture regain for modacrylic fiber (class 1) and 11% is the commercial moisture regain for rayon fiber

Barcode label/tag Each undershirts shall be individually barcoded with a label/tag in accordance with type VI, class 17 of MIL-DTL-32075 when tested as specified in 4.4.1. The label/tag shall be located so that it is completely visible on the item when folded or packaged as specified and shall cause no damage to the item.
