No appreciable change in shade or los
12、s of color of the tested specimen shall be visible when compared to the untested thread. 5/ AATCC Evaluation Procedure 2, Gray Scale for Staining 3.2 Color. The color shall be as specified in the applicable end item specification or in the contract order. The dyed thread shall conform to the applica
13、ble approved shade standard. The shade of the polyester core shall approximate that of the cotton or staple polyester covering. 3.3 Labile Sulfur. Use of dyes and compounds containing elementary sulfur capable of oxidation to sulfuric acid, is not permitted. 3.4 Finish removal procedure. Before eval
14、uation for shade matching and testing for colorfastness, except for colorfastness to wet dry cleaning, the thread shall be wet dry cleaned in accordance with AATCC-132. Excess solvent shall be removed by centrifuging or wringing. The sample shall then be rinsed in distilled water at 120 to 160F and
15、dried at a temperature not exceeding 180F. The dried sample shall then be conditioned for a minimum of 4 hours prior to evaluation for shade matching or colorfastness. 3.5 Visual shade matching. The color and appearance of the finished thread, after removal of finish (see 3.4), shall match the stand
16、ard sample when viewed using AATCC Evaluation Procedure 9, Option A, with sources stimulating artificial daylight D75 illuminant with a color temperature of 7500 + 200 K, with illumination of 100 + 20 foot candles, and shall be a good match to the standard sample under incandescent lamplight at 2856
17、 + 200 K. 3.6 Finishing materials. The finished thread shall have no chemical finishes or treatments other than those commonly used, i.e. water-repellent, etc, on commercial threads which have been demonstrated to have no deleterious effects on the polyester fiber, including effects of prolonged sto
18、rage. There shall be no noticeable wicking of any treatment to adjacent material when sewn. No finish or treatment shall be applied for the purpose of increasing breaking strength. 3.7 Non-wicking Finish. When specified, the thread shall be finished with a non-wicking finish uniformly applied. The f
19、inished thread shall resist the wicking of water when tested as specified 3.7.1. 3.7.1 Vertical Resistance to wicking: The thread shall be water repellent treated so that the treated thread shall resist the wicking of water for a period of not less than 2 hours when tested as follows: The test speci
20、men shall consist of a 20 strand skein of thread in one continuous 30 yard length made on a 54 inch periphery skein reel. The skein shall be reeled under enough tension to cause the strands in the skein to lie uniformly, side by side, on the reel. The finishing end of the skein shall be tied to the
21、starting end o f the skein in such a manner that the knot will not add additional length to the reel skein. The skein shall be hung over the movable crossbar of 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-50199A a laboratory stand with the
22、other end hanging over the vessel. The movable crossbar shall raise 28 inches or more above the base. A non-ferrous to 7/8 ounce weight shall be placed in the lower catenary of the skein to keep it taut and straight. The skein shall be arranged so that the strands are touching each other in flat rib
23、bon form. The vessel shall be filled to a depth of at least 5 inches with distilled water at room temperature which has been mixed with blue food coloring, (salt and wetting agent free). A piece of blotting paper shall be attached by means of a paper clip or similar clamp to one full side (20 strand
24、s) of the skein, 3 inches above the lower catenary of the skein. The position of crossbar shall be adjusted that when the skein is hung freely in the liquid, 2 inches of the skein will be immersed in the liquid and the lower edge of the blotter is 1 inch above the liquid surface. The skein shall the
25、n be slowly lowered into the dye bath and the time of entry shall be noted. Depending on the dimensions of the vessel and the length of the crossbar, several specimens can be tested at the same time in the same dye bath by handing the skeins sufficiently apart on the crossbar. The skein shall be exp
26、osed for 2 hours. The blotter shall be examined for wetting or staining at least every hour. The test shall be terminated whenever staining or wetting of the blotter is observed within the 2 hour test duration. 3.8 Put-up. Unless otherwise specified, the thread shall be put-up on holders such as com
27、mercial spools, cones, or tubes as specified in the contract. The thread shall be wound around the specified holder in one continuous piece, so that each turn and layer is free of entanglement. The outside ending of the thread shall be secured to prevent unwinding, loosening, or slippage during hand
28、ling, shipping, or storage. 3.9 Labeling. Each holder shall have a label, adhered securely so as to remain in place and be clearly legible until all thread has been removed. The label shall be printed and shall include information related to length in yards, direction of twist, color, size, ply, nam
29、e of thread manufacturer, weight, yards/pound and nomenclature specifying fiber and construction fiber and construction type. 3.10 Workmanship. The finished thread shall conform to the quality of product established by this document. The thread shall average not more than one full thread knot or spl
30、ice per 1,000 yards. The occurrence of defects shall not exceed the contractors own quality assurance standards and the quality assurance standards defined by the technical data in the bid package. 3.11 Toxicity. The finished fabric shall not present a health hazard when used as intended and tested
31、as specified in 4.1 4. REGULATORY REQUIREMENTS. The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). 4.1 Toxicity test.
