7. Staining Procedure
7.1 Place the unstained specimen flat on a single thickness of AATCC White Textile Blotting Paper on a smooth, horizontal surface.
7.2 Using the medicine dropper, place
5 drops (approx. 0.2 mL) of corn oil (see
12.3) in the approximate center of the test specimen.
7.3 Place a 7.6 x 7.6 cm (3.0 x 3.0 in.) square of glassine paper over the stained area.
7.4 Place the weight (see 5.5) on the glassinc paper directly over the stained area.
7.5 Allow weight to sit undisturbed for
60 ± 5 s. Then remove the weight and discard the glassine sheet.
7.6 Do not allow stained test specimens to contact each other in a manner which would transfer stains. Wash within 20 ± 5 mm after staining.
8. Washing Procedure
8.1 Fill washer to high water level with water at one of the temperatures from Table I. Check with the thermometer.
8.2 Add 100 I g of detergent to the washer.
8.3 Start the water agitating, place ballast and then test specimens in the washer making a total load of 1.80 ± 0.07 kg (4.00 ± 0.15 lb). The maximum number of test specimens per washer load shall be 30 with one stain per specimen.
8.4 Set the dial on the washer for a Normal wash to run for 12 mm measured time and allow cycle to run to completion. (This gives normal agitation in both the wash and the rinse.)
8.5 At the end of the final spin cycle. place the entire load, test specimens and ballast, into the dryer.
8.6 Dry at Normal (Couon Sturdy) setting at a time setting of 45 mm or until dry. On some dryers a 5 mm cooldown automatically follows the drying on the Normal (Cotton Sturdy) setting. For dryers without this feature dry at High setting for 45 ± 5 mm and change setting to Air and run for 5 mm. Maximum dryer stack temperature at the cabinet exit should be 65 ± 6°C (150 ± 10°F) with the heating element on.
8.7 Remove specimens from dryer immediately on completion of the cycle and lay flat to prevent formation of wrinkles or creases which can affect the stain release rating. Rate residual stains within 4 h after drying.
9. Evaluation
9.1 Mount the stain release replica on the mounting board, with the center of the standard 114 ± 3 cm (45 ± 1 in.) from the floor.
9.2 Place the test specimen hat with face up in the center of the non-glare black topped table with one edge of the table touching the mounting board. The fabric shall be rotated to be viewed from the direction which produces the lowest rating.
9.3 Viewing distance shall be 76 ± 3 cm (30 ± 1 in.) from the back mounting board, with the eye at 157 ± 15 cm (62 ± 6 in..) from the floor. The rater should stand directly in front of the specimen. Varying the viewing angle either horizontally or vertically can affect grades obtained on some fabrics.
9.4 Each rater shall independently compare the residual stain on the test specimen with the stains on the stain release replica and rate each test specimen to the nearest 0.5 grade according to Table 11.
10. Report
10.1 Calculate the average of 4 grades for each fabric, (2 judgments on each of 2 specimens), to nearest 0. 1. This is the unit of measure for this test method.
10.2 Report whether the Stain Release Replica or the 3M Stain Release Rating Scale was used.
10.3 Report the washing procedure used by appropriate Roman numeral from Table I.
10.4 If stain(s) other than the corn oil are used, identify each stain and report the stain release grade obtained for each stain separately.
10.5 Report water hardness of the washing procedure in terms of parts per million (ppm).
10.6 Report the type ballast material used.AATCC 130 pdf free download
