6.Test Specimens
6.1 Replicate sets (two sets each forlaundering and drycleaningy of simulatedpant leg specimens prepared as follows.6.2 ut one front and one back panelfor each simulated pant leg required, withthe longer 600 mm (23.5 in.) dimensionin the fabric length direction.
Place a front panel over a back panelwith the face sides together and align thelengthwise cut edges on one side. Stitchthe two panels together about 16 mm(0.625 in.) in from the cut edges,alongwith 600 mm (23.5 in.) length, using the301 stitch, 0O-3 cord sewing thread and8-10 stitches per 25 mm (1.0 in.). Next,align the opposite lengthwise cut edgesand stitch together in the same manner asabove.
Turn the tubular specimen inside out sothat the face side is on the outside.
For pant leg specimens without cuffs,turn in the top and bottom edges to form51-mm (2-in.) hems and stitch in positionabout 6 mm(0.25in.) from the rawedges. Be sure to burst open the sideseams (no pressing) before stitching inthese areas.
The patterns for the simulated pant legallow for a cuff at the bottom end. For acuffed leg, turn in and stitch the top hemas above.At the bottom, turn in a 76 mm(3-in.) length and stitch as above, thenturn up the hem to make a 38 mm (1.5in.) cuff and tack at both side seams.
NOTE 1—Separate test specimens arerequired for washing and dryeleaning.
NOTE 2—Normally creases are notpressed in simulated pant leg specimensmade from flocked fabrics.However, ifpressed-in creases are desired in flocked
fabric specimens.thc pressing procedureused should be representative of that usedby commercial manufacturers.
7.Procedure
7.1 Laundering (see 11.7)——Wash thetest specimens as part of 1.84-kg(4-lb)load.using ballast,if necessary, one ofthe automatic home type washing ma-chines described in AATCC Monograph(M)6,Standardization of Home Laundry.
Test Conditions,and one of the applicable wash temperatures for the washingmachine selected,as shown in M6 (seewww.aatcc.org for latest version of themonograph). At the completion of thedrying cycle,remove the load from thedryer and separate the pieces.
The above washing and drying proce-dure is repeated for the specified numberof wash/dry cycles. Allow for a 30-minrelaxation period between each dryingand washing.
7.2 Coin-Op Drycleaning—The testspecimens are drycleaned as part of a1.82-kg (4-lb) load, made up withdummy pieces of drycleanable fabrics.The coin-op unit with perchloroethylenesolvent (about 1% charge system) shallbe run for the full cycle which includes tumble drying. At the end of each dry-cleaning cycle, remove the load from theunit, and separate the pieces.
The above drycleaning is repeated forthe desired number of cycles.Allow for a30-min relaxation period between dry-cleanings.
8. Evaluation
8.1 After the desired number of laun-dering or drycleaning cycles， specimensare opened and laid flat with the sideseam in the center of the examinationarea.
8.2 Compare the edgewear at hems,cuffs and seams as above prepared withthe AATCC comparison photographs andrate using a ranking scale of:
5—None
4—Slight
3—Noticeable
2—Considerable
1—Severe
8.2.1 Take care to ensure that the rat-ing is based on flock loss and not on flat-tened or matted pile that can be restoredby methods such as brushing. A magni-fying glass is often required to make thisjudgment.
9. Report
9.1 Report the grade determined in 8.2and also report the number of launderingand/or drycleaning cycles at which theranking value was obtained.
10. Precision
10.1 Precisiow. Laundering——Intralaboratory repeatability a 0.20 ranking unit.laundering—Interlaboratory reproduc-ibility 0.30 ranking unit.
Drycleaning—Intralaboratory repeat-ability o ±0.25 ranking unit.
Drycleaning—Interlaboratory reproducibility o ±0.60 ranking unit.
10.2 Bias.Appearance of flocked fabrics after repeated home laundering and/or coin-op drycleaning can be definedonly in terms of a test method. There isno independent method for determiningthe true value. As a means of estimatingthis property,the method has no knownbias.AATCC 142 pdf download.Appearance of Flocked Fabrics after Repeated
