AATCC 142-2016 Appearance of Flocked Fabrics after Repeated Home Laundering and/or Coin-Op Drycleaning.
6. Test Specimens
6.1 Replicate sets (two sets each for laundering and drycleaning) of simulated pant leg specimens prepared as follows.
6.2 Cut one front and one back panel for each simulated pant leg required, with the longer 600 mm (23.5 in.) dimension in the fabric length direction. Place a front panel over a back panel with the face sides together and align the lengthwise cut edges on one side. Stitch the two panels together about 16 mm (0.625 in.) in from the cut edges, along with 600 mm (23.5 in.) length, using the 301 stitch, 00-3 cord sewing thread and 8-10 stitches per 25 mm (1.0 in.). Next, align the opposite lengthwise cut edges and stitch together in the same manner as above. Turn the tubular specimen inside out so that the face side is on the outside. For pant leg specimens without cuffs, turn in the top and bottom edges to form 51-mm (2-in.) hems and stitch in position about 6 mm (0.25 in.) from the raw edges. Be sure to burst open the side seams (no pressing) before stitching in these areas. The patterns for the simulated pant leg allow for a cuff at the bottom end. For a cuffed leg, turn in and stitch the top hem as above. At the bottom, turn in a 76 mm (3-in.) length and stitch as above, then turn up the hem to make a 38 mm (1.5 in.) cuff and tack at both side seams. NOTE 1—Separate test specimens are required for washing and drycleaning. NOTE 2—Normally creases are not pressed in simulated pant leg specimens made from flocked fabrics. However, if pressed-in creases are desired in flocked fabric specimens, the pressing procedure used should be representative of that used by commercial manufacturers.
7.1 Laundering (see 11.7)—Wash the test specimens as part of 1.84-kg (4-lb) load, using ballast, if necessary, one of the automatic home type washing ma- chines described in AATCC Monograph (M) 6, Standardization of Home Laundry Test Conditions, and one of the applica- ble wash temperatures for the washing machine selected, as shown in M6 (see www.aatcc.org for latest version of the monograph). At the completion of the drying cycle, remove the load from the dryer and separate the pieces. The above washing and drying proce- dure is repeated for the specified number of wash/dry cycles. Allow for a 30-min relaxation period between each drying and washing.
7.2 Coin-Op Drycleaning—The test specimens are drycleaned as part of a 1.82-kg (4-lb) load, made up with dummy pieces of drycleanable fabrics. The coin-op unit with perchloroethylene solvent (about 1% charge system) shall be run for the full cycle which includes tumble drying. At the end of each dry- cleaning cycle, remove the load from the unit, and separate the pieces.AATCC 142 pdf download.
