Significance and Use4.1 This specification may be used to evaluate pertinentperformance characteristics of washable and drycleanable softwindow coverings, whether lined or unlined.4.1.1 Soft window
10、covering characteristics to be evaluatedprior to repeated refurbishing include, but are not limited to,seam strength and appearance, uniformity 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 refurb
11、ishing include, but are not limited to,colorfastness, dimensional change, seam strength, appearance,and compatibility of components. Compatibility of dimen-sional change between drapery fabric and lining should benoted.4.2 The specified home laundry machine settings do notreflect advances in cycle d
12、esign or special features of washerand dryers which enhance the performance of these products.The standard washing and drying procedure reflects the mini-mum capabilities of current home laundering equipment usedby consumers in accordance with care label instructions.4.2.1 The reproducibility of the
13、 results of the test methodspecified in 9.2 depends on the use of procedures for automatichome laundering as specified on care labels.1This specification is under the jurisdiction of ASTM Committee D13 onTextiles and is the direct responsibility of Subcommittee D13.63 on HomeFurnishings.Current edit

Sampling, Selection, and Number of Specimens5.1 Division into LotsFor acceptance testing, divide theproduct into lots as agreed upon by the purchaser and t
17、hesupplier.5.2 Lot SampleAs a lot sample for acceptance testing,take at random the number of shipping cartons 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.N
18、OTE 1A realistic specification or other agreement between thepurchaser and the supplier requires taking 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, cons
19、umers risk, acceptable quality level, andlimiting quality level.5.3 Laboratory SampleAs a laboratory sample 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 indivi

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 Characteris
21、tics7.1 The fabric in the item shall be evaluated as directed inSpecification D 3691.8. Product Performance 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
22、.8.2 Mark and record measurements as directed in Section 11of this specification to establish size consistency, side to sideand part 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 commercial
23、lyavailable laboratory light source as agreed upon by purchaserand supplier.8.4 Examine soft window coverings for any other pertinentdefects.9. Refurbishing Conditions9.1 Laundering:9.1.1 Launder soft window coverings as directed inAATCCMethod 135 as in the permanently attached care label instruc-ti
24、ons. Use laundering temperatures as directed in AATCCMethod 135.9.1.2 Any domestically available detergent, 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
25、% available chlorine) into the washerin the manner directed on the bleach container. When testingwith non-chlorine 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
26、 135.9.1.5 When ironing is to be done, follow the methodindicated on the care label or as directed in AATCCMethod 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 t
27、he permanently attached care labelinstructions.9.2.2 Repeat the procedure two or more times as agreedupon by purchaser and supplier.10. Soft Window Coverings Performance CharacteristicsAfter Refurbishing10.1 Remeasure as directed in Section 11. Record measure-ments and calculate dimensional change u
28、sing measurementspreviously obtained in 8.2. Dimensional change may beexpressed as a percentage using the following 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 negativ
29、e dimensional change indicates shrinkage and posi-tive dimensional change indicates growth.10.2 Examine soft 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 cove
30、rings for appearance of allseams in accordance with AATCC Method 88B. Acceptableperformance requirements should be as agreed between pur-chaser and supplier.10.4 Evaluate durable press items for appearance as directedin AATCC Method 143.

Measuring Soft 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.D472008211.3 Unless
32、 otherwise set by mutual agreement betweenpurchaser and supplier, make original measurement marks atthe locations according 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 ea
33、ch panel separately(AA,Fig. 1).11.3.2 Measure width of soft window coverings at top,middle, and bottom (if it is a pinch pleated item, then measurethe heading only, including all ruffles, flounces and trims).Measure each panel separately (B B, Fig. 1).11.3.3 Mark the inner edge of ruffle or flounce
34、whereattached to item with 25-cm (10-in.) or 91.4-cm (36-in.) gagemarks (D D, Fig. 1). Permitting all fullness 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 pa
35、nel of fabric, excluding ruffles andflounces, on both face and back of the product, mark off witha suitable 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.). Eac
36、h set of the gage marks must be at least5.0 cm (2 in.) from all edges of the panel and approximately 12cm (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 widt
37、h measurements are made, thetolerances shall be to the nearest 1 mm (116 in.). When gage marks areused, the measurement tolerances should be supplied by the gagemanufacturer.
