19、d-in 4.4.3. 3.4 Color. 3.4.1 Color, classes 1 and IA. The color shall be the six color Desert Camouflage Pattern. The cloth shall be dyed to a ground shade either match- ing or approximating Light Tan 379 and then overprinted with the camouflage pattern by roller or autamatic screen printing. When t
20、he ground shade is dyed to match Light Tan 379, the five remaining colors shall be obtained by subsequent printing using five rollers or screens as appropriate for the Tan 380, Light Brawn 381, Dark Brawn 382, Black 383, and Khaki 384 areas of the pattern. When the ground shade is dyed to approximat
21、e Light Tan 379, all six colors of the camouflage pattern shall be obtained by subsequent printing using six rollers or screens to match all six colors. The ground shade dying and the overprinting shall be accomplished with organic colorants (see 6.6.1). Resin bonded pigments are not permitted. The
22、dyed and printed cloth shall conform to the spectral reflectance requiremnts specified in 3.6.1. 3.4.2 Color, classes 3, 3A, and 3B. The color shall be the three color Desert Camouflage Pattern. The cloth shall be dyed to a ground shade either matching or approximating Light Tan 492 and then overpri

The printed finished cloth shall shuw fastness to light (after 40 standard fading hours), laundering (after 3 cycles), and perspiration eq
29、ual to or better than the standard sample or equal to or better than a rating of “good“ for all the pattern areas, except fastness to light shall be equal to or better than “fair“ for classes 3, 3A and 3B. The cloth shall shuw fastness to crocking equal to or better than the standard sample or shall
30、 have an AATCC Chromatic Transference Scale rating of not luwer than 3.5 for all the pattern areas, except for Black 383, classes 1 and fi, which shall have an AATCC Chromatic Transference Scale rating of not luwer than 1.5. The light tan areas should be tested for crocking on the . back side. Testi
31、ng shall be as specified in 4.4.3. 3.5 Pattern execution, classes 1, lA, 3, 3A and 3B. The pattern of the finished cloth shall match the standard sample with respect to design, . colors, and registration of the respective areas. The warpvise pattern repeat of the dyed and printed finished cloth shal
32、l be 16.75 +1.25 -1.75 inches (see 6.10). Each pattern area shall Shaw solid coverage. Skitteriness exceeding that sham by the standard sample in any of the printed areas will not be acceptable. When a standard sample is not referenced for pattern execution, a pattern drawing shall be provided and t
33、he pattern of the finished cloth shall match that of Drawing 2-1-1884 for classes 1 and lA and 2-1-2240 for classes 3, 3A and 3B (see 2.1 and 6.4). 3.6 Spectral reflectance. 3.6.1 Spectral reflectance, classes 1 and lA.
