8、ains, draperies, or otheraccessories on wall or window openings that are either lined orunlined and primarily constructed of textile fabrics.3.1.1.1 DiscussionWashable soft window coverings in-clude those that can be refurbished by any procedure in whichthe cleaning solvent is water. Drycleanable so
9、ft windowcoverings include those that should be refurbished by anyprocedure in which the cleaning solvent is primarily nonaque-ous and used in drycleaning.3.2 For definitions of textile terms used in this practice referto Terminology D 123 and Terminology D 3136.4. Significance and Use4.1 This pract
10、ice may be used to evaluate pertinent perfor-mance characteristics of washable and drycleanable soft win-dow coverings, whether lined or unlined.4.1.1 Soft window covering characteristics to be evaluatedprior to repeated refurbishing include, but are not limited to,seam strength and appearance, unif
11、ormity of shade (part topart), and size consistency (side to side and part to part).4.1.2 Soft window covering characteristics to be evaluatedafter repeated refurbishing include, but are not limited to,colorfastness, dimensional change, seam strength, appearance,and compatibility of components. Comp
12、atibility of dimen-sional change between drapery fabric and lining should benoted.4.2 The specified home laundry machine settings do notreflect advances in cycle design or special features of washerand dryers which enhance the performance of these products.The standard washing and drying procedure r
13、eflects the mini-mum capabilities of current home laundering equipment usedby consumers in accordance with care label instructions.4.2.1 The reproducibility of the results of the test methodspecified in 9.2 depends on the use of procedures for automatichome laundering as specified on care labels.4.3
14、 The areas to be evaluated and the criteria assigned tothese areas shall be set by mutual agreement between purchaserand supplier.5. Sampling, Selection, and Number of Specimens5.1 Division into LotsFor acceptance testing, divide theproduct into lots as agreed upon by the purchaser and thesupplier.1

17、rtons directed in anapplicable material specification or other agreement betweenthe purchaser and the supplier. Consider shipping cartons ofcurtains or draperies to be the primary sampling units.NOTE 1A realistic specification or other agreement between thepurchaser and the supplier requires taking
18、into account the variabilitybetween shipping cartons, between items within a carton, and betweenspecimens within an item so as to provide a sampling plan which has ameaningful producers risk, consumers risk, acceptable quality level, andlimiting quality level.5.3 Laboratory SampleAs a laboratory sam
19、ple for accep-tance testing, take two random items from each shipping cartonin the lot sample.5.4 Test SpecimensTake test specimens from each item inthe laboratory sample as directed in the individual test meth-ods. Perform each test on the product as it will reach theconsumer.CHARACTERISTICS AND TE
20、ST METHODS6. Characteristics6.1 The areas to be evaluated and the criteria assigned tothose areas shall be set by mutual agreement between pur-chaser and supplier.7. Fabric Performance Characteristics7.1 The fabric in the item shall be evaluated as directed inSpecification D 3691.8. Product Performa
21、nce Characteristics Prior toRefurbishing8.1 Seam performance shall be evaluated as directed in TestMethod D 1683 (for woven) or Test Method D 3940 (for knit)and in AATCC Method 88B, as appropriate.8.2 Mark and record measurements as directed in Section 11of this practice to establish size consistenc
22、y, side to side andpart to part, and as a basis for determining dimensionalchanges.8.3 Examine the soft window coverings for unacceptableshade difference from part to part, using a commerciallyavailable laboratory light source as agreed upon by purchaserand supplier.8.4 Examine soft window coverings
23、 for any other pertinentdefects.9. Refurbishing Conditions9.1 Laundering:9.1.1 Launder soft window coverings as directed in AATCCMethod 135 as in the permanently attached care label instruc-tions. Use laundering temperatures as directed in AATCCMethod 135.9.1.2 Any domestically available detergent,
24、as agreed uponby purchaser and supplier, may be used.9.1.3 When chlorine bleach is to be used, introduce one cupof any liquid chlorine household bleach containing 5.25 %sodium hypochlorite (5 % available chlorine) into the washerin the manner directed on the bleach container. When testingwith non-ch
25、lorine bleach is indicated, introduce it into thewasher in the amount and manner directed on the bleachcontainer.9.1.4 Dry items following care label instructions or asdirected in AATCC Method 135.9.1.5 When ironing is to be done, follow the methodindicated on the care label or as directed in AATCCM
26、ethod 135.9.1.6 Repeat the complete cycle four more times or asagreed upon by purchaser and supplier.9.2 Drycleaning:9.2.1 Dryclean soft window coverings as directed inAATCC Method 158 or in the permanently attached care labelinstructions.9.2.2 Repeat the procedure two or more times as agreedupon by
27、 purchaser and supplier.10. Soft Window Coverings Performance CharacteristicsAfter Refurbishing10.1 Remeasure as directed in Section 11. Record measure-ments and calculate dimensional change using measurementspreviously obtained in 8.2. Dimensional change may beexpressed as a percentage using the fo
28、llowing equation:D 5 100 A 2 B!/Bwhere:D = dimensional change, %,B = measurement before refurbishing, mm (in.), andA = measurement of same dimension after refurbishing,mm (in.).NOTE 2A negative dimensional change indicates shrinkage and posi-tive dimensional change indicates growth.10.2 Examine soft
29、 window coverings for unacceptableshade difference from part to part, as directed in 8.3 and for anyother pertinent defects after refurbishing as directed in 8.4.10.3 Evaluate soft window coverings for appearance of allseams in accordance with AATCC Method 88B. Acceptableperformance requirements sho
30、uld be as agreed between pur-chaser and supplier.10.4 Evaluate durable press items for appearance as directedin AATCC Method 143. Acceptable performance requirementsshould be by agreement between purchaser and supplier.10.5 Examine soft window coverings for any other pertinentdefects.11. Measuring S
31、oft Window Coverings11.1 Expose the item to standard textile conditions for atleast 4 h.11.2 When necessary, mark the dimension to be measuredwith a suitable marking device.11.3 Unless otherwise set by mutual agreement betweenpurchaser and supplier, make original measurement marks atthe locations ac
32、cording to Fig. 1, as follows:11.3.1 Measure length of soft window coverings at eachside of each panel, and in the middle of the panel, includingruffles, flounces and trims. Measure each panel separately(A A, Fig. 1).11.3.2 Measure width of soft window coverings at top,middle, and bottom (if it is a
33、 pinch pleated item, then measurethe heading only, including all ruffles, flounces and trims).Measure each panel separately (B B, Fig. 1).D 4720211.3.3 Mark the inner edge of ruffle or flounce whereattached to item with 25-cm (10-in.) or 91.4-cm (36-in.) gagemarks (D D, Fig. 1). Permitting all fulln
34、ess to remain, markthe outer edge of the ruffle or flounce with corresponding gagemarks (E, Fig. 1). Measure the full fabric width betweensecond set of gage marks (E E, Fig. 1).11.3.4 On one panel of fabric, excluding ruffles andflounces, on both face and back of the product, mark off witha suitable
35、 marking device, three 25-cm (10-in.) gage marksparallel to the length of the fabric, and three 25-cm (10-in.)gage marks parallel to the width of the fabric to the nearest0.25 cm (0.1 in.). Each set of the gage marks must be at least5.0 cm (2 in.) from all edges of the panel and approximately 12cm (
36、5 in.) apart. Bench marks of 50 cm (20 in.) are commonlyused to facilitate better precision of measuring, so use thismeasurement if the product is large enough.NOTE 3When actual length and width measurements are made, thetolerances shall be to the nearest 1 mm (116 in.). When gage marks areused, the
37、 measurement tolerances should be supplied by the gagemanufacturer. See Test Methods D 3773.REPORTING AND CONFORMANCE12.
