The pre-cautions are ancillary to the testing proce-dures and are not intended to be all inclu-sive. It is the users responsibility to usesafe and proper techniques in handlingmaterial

11、s in this test method. Manufac-turers MUST be consulted for specificdetails such as material safety data sheetsand other manufacturers recommenda-tions. All OSHA standards and rulesmust also be consulted and followed.4.1 Good laboratory practices shouldbe followed. Wear safety glasses in alllaborato

12、ry areas.4.2 The 1993 AATCC Standard Refer-ence Detergent and the 2003 AATCCStandard Reference Liquid Detergentmay cause irritation. Care should betaken to prevent exposure to skin andeyes.4.3 All chemicals should be handledwith care.4.4 Manufacturers safety recommen-dations should be followed when

13、operat-ing laboratory testing equipment.4.5 When evaluating crease retention,use of a lamp with a shield can aid in pre-vention of burns that could result fromlamp heat.5. Uses and Limitations5.1 This test method is designed to beused for evaluating the appearance of ap-parel or other textile end pr

14、oducts pro-duced with washable fabric after repeatedhome laundering.5.2 The test procedure is designed toreflect the capabilities of home laundryequipment which is currently used byconsumers. In general, it is preferable toconduct the test under relatively severelaundering conditions.5.3 Prints and

15、patterns may mask themussiness present in textile end products.The rating process is, however, based onthe visual appearance of specimens in-cluding such effects.5.4 The interlaboratory reproducibilityof the results of this test method dependsupon mutual agreement by users of themethod on the washin

Additional information onthe machine and laundering conditionsmay be found in the monograph, Stan-dardization of Home Laundry Te

24、st Con-ditions, elsewhere in this TECHNICALMANUAL.8.1.1 It is recognized that special cy-cles or features are available on currentwashing machines and dryers to achieveimproved performance on certain items;i.e., gentle cycles with reduced agitationto protect delicately constructed items,and durable

25、press cycles, with cool-downor cold rinses and reduced spin speeds, tominimize wrinkling. In evaluating ap-pearance retention, however, the more se-vere Normal or Cotton Sturdy machinecycle is considered most appropriate. Ifmodifications to any of the cycles (see8.2) are used, these must be reported

26、 inthe results (see Section 10).8.2 Standard washing.8.2.1 Hand Wash(see 12.7). Dis-solve 20.0 0.1 g of 1993 AATCC Stan-dard Reference Detergent or 30.3 0.1 gof 2003 AATCC Standard Reference Liq-uid Detergent in 7.57 0.06 L (2.00 0.02 gal) of water at 41 3C (105 5F)in a 9.5 L (10.0 qt) pail and then

27、 add thethree textile end product specimens.Wash for 2.0 0.1 min with no twistingor wringing. Rinse once using 7.57 0.06 L (2.00 0.02 gal) of water at 41 3C (105 5F). Remove the specimensand dry by Procedure C, Drip (see 8.3.3).8.2.2 Machine WashUse specifiedwater level, the selected water tempera-t

28、ure for the washing cycle and a rinsetemperature of less than 29C (85F). Ifthis rinse temperature is not attainable,record available rinse temperature.8.2.3 Add 66.0 0.1 g of 1993AATCC Standard Reference Detergent or100 0.1 g of 2003 Standard ReferenceLiquid Detergent.

32、duct speci-mens and enough ballast to make a 1.8 0.06 kg (4.00 0.13 lb) load. Evaluationof heavy textile end product items mayrequire the addition of ballast beyond the1.8 kg limit to balance the load wheredistribution is a problem. A weight limitof 2.7 0.06 kg (6.00 0.13 lb) may thenbe used and not

33、ed in the report. Set thewasher for the selected washing cycleand time (see Tables II and III). Normalor Cotton Sturdy is recommended. Forvery critical evaluations and in arbitra-tion, limit the number of specimens perwasher load to those from one sample.8.2.5 For specimens to be dried by Pro-cedure

34、s A, B or D, allow washing to pro-ceed automatically through the final spincycle. Remove the test specimens imme-diately after the final spin cycle, separatetangled pieces, taking care to minimizedistortion, and dry by Procedure A, B orD (see Tables II and IV).8.2.6 For specimens to be dried by Pro-

35、cedure C, Drip Dry, remove the speci-mens from the washer just before thewater begins to drain for the final rinsecycle. Remove specimens soaking wet.8.2.7 Washer creases. Specimens maybe in a folded or creased state after wash-ing. Such folds or creases should be re-moved by hand prior to drying.8.

36、3 Drying.8.3.1 (A) Tumble Dry. Place thewashed load (test specimens and ballast)in the tumble dryer and set the tempera-ture control to generate the correct ex-haust temperatures as specified in TableIV. For fibers that are heat sensitive,lower temperatures consistent with pro-ducers recommendations

37、 are required,and must be reported. Operate the dryeruntil the total load is dry. Remove theload immediately after the machine stops.Avoid overdrying. Static cling becomes aproblem with overdrying, particularlywith lightweight items, because it pre-vents the specimens from tumbling freely.8.3.2 (B)

38、Line Dry. Textile end productitems are to be hung on an appropriatehanger, straightening and smoothing fac-ings, seams, etc. Allow specimens tohang in still air at room temperature untildry.8.3.3 (C) Drip Dry. Textile end productitems should be hung as described in8.3.2. Allow specimens to hang in s

39、till airat room temperature until dry.8.3.4 (D) Screen Dry. Spread eachspecimen on a horizontal screen or perfo-rated surface, removing wrinkles but notdistorting or stretching the specimen. Al-low the specimens to dry in still air atroom temperature.8.3.5 Dryer creases. If specimens arefolded or cr

40、eased after any drying cyclebut the last, they should be rewet and anattempt should be made to remove thecreases by ironing with a hand iron at atemperature suitable for the fabric beingtested prior to the specimens being sub-jected to additional washing and dryingcycles. No attempt to remove wrinkl

41、es orcreases by hand ironing should be madeafter the final drying cycle.8.4 Repeat the selected washing anddrying cycles four more times or to anagreed number of cycles.8.5 Prior to evaluation, preconditionand then condition test specimens asA. For single needle seams. B. For double needle seams.Fig

43、/2007 TM 143-2006 251directed in ASTM D 1776, Standard Prac-tice for Conditioning and Testing Textiles(see 12.6). Condition the test specimensfor a minimum of 4 h in the standard at-mosphere for textile testing 21 1C (70 2F) and 65 2% RH. Textile endproduct items should be hung for condi-tioning as

44、described in 8.3.2.9. Evaluation9.1 Three trained observers should rateeach test specimen independently.9.2 The overhead fluorescent lightshould be the only light source for theviewing board. All other lights in theroom should be turned off except whenrating crease appearance. In that case thefloor

45、lamp with reflector and light shield,positioned as shown in Fig. 2, is alsorequired.9.3 The observer is to stand directly infront of the specimen 1.2 0.3 m (4 ft 1 in.) away from the board. It has beenfound that normal variations in the heightof the observer above and below the arbi-trary 1.5 m (5.0

46、 ft) eye level have no sig-nificant effect on the grade given.9.4 Smoothness Appearance.9.4.1 Mount the test specimen on theviewing board as illustrated in Fig. 1,with the fabric length in the vertical di-rection. Place the most similar three-di-mensional plastic replicas on each side ofthe test spe

47、cimen to facilitate compara-tive rating.9.4.2 Although the 3-D SmoothnessAppearance (SA) replicas were cast fromwoven fabrics, it is understood that thesewrinkled surfaces do not duplicate allpossibilities of fabric surfaces. The repli-cas are to be used as guides which repre-sent various levels of

48、fabric smoothnessor freedom from wrinkles. The observershould mentally integrate degree and fre-quency of wrinkles in the specimen to de-termine a level of smoothness that can beidentified with the SA replica numberwhich most nearly represents thatsmoothness appearance level; see TableV.9.4.3 Assign

49、 the numerical grade of thereplica which most nearly matches thesmoothness appearance of the test speci-men, or assign a grade midway betweenthose whole-number standards whichhave no half-number standards separatingthem (SA-1.5, SA-2.5, SA-4.5) if the ap-pearance of the test specimen warrants it.9.4.4 An SA-5 grade is equivalent tothe SA-5 replica and represents thesmoothest appearance, while an SA-1replica represents very poor appe
