Purpose and Scope1.1 These accelerated laundering testsare to evaluate the colorfastness to laun-dering of textiles which are expected towithstand frequent laundering. The fabr

However, the staining ef-fect produced by five typical hand orhome launderings cannot a

4、lways be pre-dicted by the 45 min test. Staining is afunction of the ratio of colored to undyedfabrics, fiber content of fabrics in thewash load and other end-use conditionswhich are not always predictable.1.2 When this test method was origi-nally developed, various options of thismethod were intend

5、ed to evaluate thecolor change and staining by five homeor commercial launderings, on an accel-erated basis. Throughout the years, com-mercial laundering procedures havechanged and commercial cleaning todayinvolves many different types of pro-cesses, dependent on the type of productbeing cleaned tha

The colorchange is obtained in a convenientlyshort time. The abrasive action is a resultof the frictional effects of fabric agains

All OSHA standards and rulesmust also be consulted and followed.4.1 Good laboratory practices shouldbe followed. Wear safety glasses in alllaboratory areas.4.

12、2 All chemicals should be handledwith care.4.3 The 1993 AATCC Standard Refer-ence Detergent WOB may cause irrita-tion. Care should be taken to prevent ex-posure to skin and eyes.4.4 An eyewash/safety shower shouldbe located nearby for emergency use.4.5 Manufacturers safety recommen-dations should be

Todetermine staining in Test No. 3A, use ei-ther multifiber test fabric or bleached cot-ton test fabric. With respect to Test No. 3A,the use of multifiber test fabric is optionalbut th

23、e staining of acetate, nylon, polyesterand acrylic is disregarded unless one ofthese fibers is present in the fabric beingtested or known to be in the final garment.For Test 3A, multifiber test fabric withheat-sealed edges is recommended. Stain-ing is not determined in Tests No. 4A and5A (see 12.10

24、and 12.11).6.4 Specimen preparation.6.4.1 Preparation with multifiber testfabric with individual component bands8 mm (0.33 in.) wide or with bleachedcotton test fabric. Prepare pieces with a50 mm (2.0 in.) square of multifiber testfabric cloth or bleached cotton test fabric(as required) sewn, staple

25、d or suitablyattached along one 50 mm (2.0 in.) edgeof the test specimen and in contact withthe face of the material. When multifibertest fabric is used, attach it so that each ofthe six fiber bands is along the 50 mm(2.0 in.) edge of the specimen with thewool on the right. The fiber bands in themul

26、tifiber test fabric will be parallel to thelengthwise direction of the test specimen.6.4.2 Preparation with multifiber testfabric with individual component bands15 mm (0.6 in.) wide. Prepare pieces witha 50 100 mm (2.0 4.0 in.) rectangle ofmultifiber test fabric sewn, stapled orsuitably attached cen

27、tered along one 100mm (4.0 in.) or 150 mm (6.0 in.) edge ofthe test specimen and in contact with theface of the material. Attach it so that eachof the six fiber bands will be parallel tothe widthwise direction of the specimen.Attach and secure the wool band at thetop of the specimen to avoid fiber l

28、oss.6.4.3 It is recommended that knittedfabrics be sewn or stapled at the fouredges to equivalent size pieces ofbleached cotton test fabric to avoid rollededges and to assist in obtaining a uniformtest result over the entire surface. Attachthe multifiber test fabric to the face of theknitted fabric.

29、6.4.4 For pile fabric specimens with apile lay direction, attach the multifibertest fabric at the top of the specimen withthe pile lay direction pointing away fromthe top of the specimen.6.5 When the textile to be tested isyarn, specimens may be tested using Op-tion 1 or Option 2.6.5.1 Option 1.

Keep one knittedspecimen of each sample as an unwashedoriginal.6.5.2 Option 2. Prepare two 110 m(120 yd) skeins of each yarn. Fold theskein so that there is a uniform amount ofyar

31、n across a 50 mm (2 in.) width with alength appropriate for the procedure to beused. Keep one skein of each sample asan unwashed original. Sew or stapleCrockmeter test cloth squares (see 12.9)or squares of bleached cotton test fabrichaving approximately the same weightfolded over each end of the lay

32、ered yarnspecimen. Attach a multifiber test fabricaccording to 6.4.1 or 6.4.2.7. Procedure7.1 Table I summarizes the conditionsof the tests.7.2 Adjust the laundering machine tomaintain the designated bath tempera-ture. Prepare the required volume ofwash liquor. Preheat this solution to theprescribed

33、 temperature.7.3 Run Test No. 1A in 75 125 mm(3.0 5.0 in.) lever lock stainless steelcanisters. Run Tests No. 2A, 3A, 4A and5A in 90 200 mm (3.5 8.0 in.) leverlock stainless steel canisters.7.3.1 For Tests No. 1A, 2A and 3A,add to the canister the amount of deter-gent solution designated in Table I.

34、7.3.2 For Test No. 4A, prepare a 1500ppm available chlorine solution. For 1 L,determine the amount of stock sodiumhypochlorite bleach solution (see 12.8) todilute as follows:159.4/% NaOCl = g to addWeigh the correct amount of bleach intoa volumetric flask and dilute to 1 L. Toeach canister, add 5 mL

35、 of 1500 ppmavailable chlorine solution and 45 mL ofdetergent solution making a total volumeof 50 mL.7.3.3 For Test No. 5A, determine theamount of stock sodium hypochloritebleach solution (see 12.8) to dilute asfollows:4.54/% NaOCl = g to addWeigh the correct amount of bleach intoa graduated cylinde

36、r and add detergentsolution to make a total volume of 150mL. Prepare this solution separately foreach canister.7.3.4 For all the tests, add the desig-nated number of stainless steel balls toeach canister.7.4 The two options for preheating thecanisters to the test temperature are byuse of the launder

37、ing machine or the pre-heater/storage unit. If the canisters are tobe preheated in the laundering machine,proceed to 7.4.2.7.4.1 Place the canisters in the pre-heater module at the prescribed test tem-perature. They are to remain in themodule for at least 2 min. Enter a wellcrumpled test specimen in

38、to each canister.7.4.2 Clamp the covers on the canis-ters. A Teflon fluorocarbon gasket (see5.1.6) may be inserted between the neo-prene gasket and the top of each canisterto prevent contamination of the wash so-lution by the neoprene. Fasten the 75 125 mm (3.0 5.0 in.) lever lock canis-ters vertica

39、lly and the 90 200 mm (3.5 8.0 in.) lever lock canisters horizontallyin the adapters on the rotor of the laun-dering machine in such a manner thatwhen the canisters rotate, the coversstrike the water first. Place an equal num-ber of canisters on each side of the shaft.For canisters preheated in the

40、module,proceed to 7.7.7.5 Start the rotor and run it for at least2 min to preheat the canisters.7.6 Stop the rotor and with a row ofcanisters in an upright position, unclampthe cover of one canister, enter a wellcrumpled test specimen into the solutionand replace the cover, but do not clamp it.Repea

41、t this operation until all the canis-ters in the row have been loaded. Thenclamp the covers in the same order inwhich the canisters were loaded (delayclamping the covers to allow equalizationof pressure). Repeat this operation untilall rows of canisters have been loaded.7.7 Start the laundering mach

42、ine andrun it at 40 2 rpm for 45 min.7.8 The rinsing, extracting and dryingprocedures are the same for all the tests.Stop the machine, remove the canistersand empty the contents into beakers,keeping each test specimen in a separatebeaker. Rinse each test specimen threetimes, in beakers, in distilled

43、 or deionizedwater at 40 3C (105 5F) for 1 minperiods with occasional stirring or handsqueezing. To remove excess water, cen-trifuge, blot or pass the test specimensthrough wringer rolls.
