2、t to ISO 15487.1. Purpose and Scope1.1 This test method is designed forevaluating the smoothness appearance offlat fabric and seams, and the retention ofpressed-in creases in garments and othertextile products after repeated home laun-dering.1.2 Any washable textile end productmay be evaluated for s
3、moothness appear-ance, seam smoothness and crease reten-tion using this method.1.3 Textile end products containingfabrics of any construction, such as wo-ven, knit and nonwoven, may be evalu-ated according to this method.1.4 Techniques for seaming and creas-ing are not outlined since the purpose ist
4、o evaluate textile end products as theywill be supplied from manufacturing oras ready for use. Furthermore, seaming orcreasing techniques would be controlledby fabric properties.2. Principle2.1 Textile end product items are sub-jected to standard home laundering prac-tices. A choice is provided of h
5、and or ma-chine washing, alternative machine washcycles and temperatures, and alternativedrying procedures. Evaluation is per-formed using a standard lighting andviewing area by rating the appearance ofspecimens in comparison with appropri-ate reference standards.3. Terminology3.1 appearance of text

Safety PrecautionsNOTE: These safety precautions arefor information purposes only. The pre-cautions are ancillary to the testing
11、proce-dures and are not intended to be all inclu-sive. It is the users responsibility to usesafe and proper techniques in handlingmaterials in this test method. Manufac-turers MUST be consulted for specificdetails such as material safety data sheetsand other manufacturers recommenda-tions. All OSHA
12、standards and rulesmust also be consulted and followed.4.1 Good laboratory practices shouldbe followed. Wear safety glasses in alllaboratory areas.4.2 The 1993 AATCC Standard Refer-ence Detergent may cause irritation. Careshould be taken to prevent exposure toskin and eyes.4.3 All chemicals should b
13、e handledwith care.4.4 Manufacturers safety recommen-dations should be followed when 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
14、 designed to beused only for evaluating the appearanceof washable fabrics after repeated homelaundering.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 severel
15、aundering conditions.5.3 Prints and 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
16、 by users of themethod on the washing and drying condi-tions as outlined in 8.1 and the weightingfactors to use for individual componentsof the items as described in 9.7.1.6.

In evaluating ap-pearance retention, however, the
25、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 inthe results (see Section 10).8.2 Standard washing.8.2.1 Hand Wash(see 12.7).

A weight limitof 2.7 0.06 kg (6.00 0.13 lb) may thenbe used and noted in the report. Set thewasher for the selected washing cycleand time (see Tables II and
32、 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-cedures A, B or D, allow washing to pro-ceed automatically through the final spincycle. Remove
33、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-cedure C, Drip Dry, remove the speci-mens from the washer just before thewater begins to
34、drain for the final rinsecycle. Remove specimens soaking wet.8.2.7 Washer creases. Specimens maybe in a folded or creased conformation af-ter removal from the washer. Suchcreases present after laundering should bestraightened out prior to drying.8.3 Drying.8.3.1 (A) Tumble Dry. Place thewashed load
35、(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 are required,and must be reported. Operate the drye
36、runtil 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) Line Dry. Textile end productitems are to be hung on
37、 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 still airat room temperature until dry.8.3.4 (D) Scre
38、en 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 creased after any drying cyclebut the last, they shoul
39、d be rewet and anattempt should be made to remove thecreases prior to additional washing anddrying. No attempt to remove wrinkles orcreases should be made after the fifth cy-cle of drying.8.4 Repeat the selected washing anddrying cycles four more times or to anagreed number of cycles.8.5 Prior to ev
40、aluation, preconditionand then condition test specimens asdirected 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
41、 should be hung for condi-tioning as described in 8.3.2.A. For single needle seams.B.

42、-20012559. 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 lamp with r
43、eflector 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 ft) eye le
44、vel 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 specimen to fa
45、cilitate 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 fabric smoo
46、thnessor 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 the numeri
47、cal 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
48、grade is equivalent tothe SA-5 replica and represents thesmoothest appearance, while an SA-1replica represents very poor appearance.9.4.5 If dryer creases are present onany specimens to be evaluated, take carein rating the specimens. Some dryercreases can be disregarded (commonlycalled “reading out”
49、). When the grade ofa dryer creased specimen differs from theother specimens by more than one grade,the test should be repeated with newspecimens, taking all precautions toavoid the occurrence of dryer creases.9.5 Appearance of Seams.9.5.1 Mount the test specimen on theviewing board with the seam in
50、 the verti-cal direction. Place the appropriate sin-gle- or double-needle standard seamsmoothness (SS) replicas beside the spec-imen to facilitate comparative rating.9.5.2 Confine observations to the areainfluenced by the seam and disregard theappearance of the surrounding fabric.9.5.3 Assign the nu
51、merical grade of thephotographic standard which most nearlymatches the appearance of the seam inthe test specimen.9.5.4 A seam smoothness grade of SS-5 is equivalent to the appearance of Stan-dard No. 5, the best level of seam appear-ance; a seam smoothness grade of SS-1 isequivalent to that of Stan
52、dard No. 1,which represents a very poor level ofseam appearance.9.6 Appearance of Creases.9.6.1 Mount the test specimen on theviewing board with the crease in the ver-tical direction.

62、re or less important tothe overall appearance of the item,weighting factors should be added to theRating Chart.9.7.3 The weighting factors to be as-signed to each component are:3Very important to overall item ap-pearance.2Moderately important to overallitem appearance.1Slightly important to overall
63、itemappearance.9.7.4 Mount the item on the viewingboard so that the center of the area orcomponent to be rated is approximately1.5 m (5.0 ft) from the floor as illustratedin Fig. 1. Place the appropriate three-dimensional plastic replicas or photo-graphs in proper position to facilitatecomparative r
64、ating (refer to 9.4, 9.5, or9.6).9.7.5 If the item is exceptionally large,such as a sheet, comforter, bedspread,curtain or drapery, fold the item length-wise to produce a panel half the originalwidth. Place this half panel over a rod sothat the fabric length is vertical and thefolded item is in equa
65、l quarters. The rodshould be sufficiently long to accommo-date the half width item. The rod with thelarge item is attached to the rating boardat approximately 1.8 m (6.0 ft) from thefloor. The standard replicas or photo-graphs are positioned to facilitate com-parative rating. Evaluate the area acros
66、sthe full width of the quartered panel at thesame eye level as the replicas. Evaluateall four quarters in the same manner andreport average grade for each componentevaluated in the test item.10. Report10.1 Option 1Using Weighting Fac-torsTotal the weighting factors as-signed to each component in the
67、 ratingchart (Fig. 6) and multiply by 5. Thisgives the maximum point value achiev-able by the item. Multiply the averagegrade recorded for each component by itsassigned weighting factor. Total thesevalues to obtain the actual point valueachieved by the item. Report as the per-centile value of the it
68、em the number ob-tained by dividing the actual point valueby the maximum point value achievableand multiplying by 100. This value is theunit of measure of this test method.10.2 Option 2Report average gradeson each individual component of eachtest item, using the Average Grade col-umn of the Rating C
