1、Designation: D6544 11Standard Practice forPreparation of Textiles Prior to Ultraviolet (UV)Transmission Testing1This standard is issued under the fixed designation D6544; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers standardized exposures to launder-ing, simulated sunlight, and chlorinated pool water to whichclo
3、th, labeled as ultraviolet-(UV) protective, must be exposedprior to testing for UV transmission.1.2 This practice leads to measurement of the residual levelof UV-protection in fabrics or garments labeled as sun- orUV-protective, after exposure to conditions that relate to abouttwo years of seasonal
4、use. The UV transmission measurementsmay be done in accordance with AATCC Test Method 183using fabrics prepared in accordance with this practice. Thismeasurement may be used in support of a label statementregarding UV protection.1.3 The values stated in SI units are to be regarded as thestandard. Th
5、e values given in parentheses are for informationonly.1.4 This standard does not purport to address the safetyconcerns, if any, associated with its use.

Terminology3.1 DefinitionsFor definitions of other textile terms usedin this practice, refer to Terminology D123 and the Glossary ofAATCC Standard Terminology.4. Summary of Practice4.1 This practice directs the exposure of cloth, labeled asUV-protective,
10、to conditions of laundering, simulated sunlight,and chlorinated pool water generally known to affect UVtransmittance.4.2 This practice directs selection and sequencing of expo-sure conditions for UV-protective fabrics and garments.5. Significance and Use5.1 The significance of this practice is that
11、cloth, labeled asUV-protective, which will ultimately be submitted for UVtransmittance testing will be in a state that simulates theircondition at the end of two years of normal seasonal use.Therefore, the UV-protection level ultimately placed on a labelestimates the maximum UV transmittance of the
12、garmentfabric during a two-year life cycle.6.

16、or production run in accordance with PracticeE122.6.2 Laboratory Sampling Unit:6.2.1 Take the number of laboratory sampling units from theprimary sampling unit in accordance with Practice E122.6.2.2 Rolls or Bolts of FabricTake from each primarysampling unit one full-width piece of fabric that is ab
17、out 1 m(1 yd) in length along the selvage (machine direction), afterremoving a first 1-mm length. For narrow fabrics, a longersample length may be required to meet the test specimenrequirements.6.2.3 GarmentsTake from each primary sampling unitone entire garment. For small garments, such as children
18、s,where sufficient material is not available to meet the three testspecimens requirement, take a pair of garments and treat as onesampling unit.6.3 LaunderingUnless exempt from laundering, launderthe laboratory sampling unit or a section of it that is at least 380by 380 mm (15 by 15 in.) using expos
19、ure conditions asdescribed in 8.1. If the laboratory sampling unit does not havethe minimum 380-mm dimension, then take a section that is atleast 1450 cm2(225 in.2). For small samples, it may benecessary to seal the edges to prevent raveling during launder-ing.6.4 Test SpecimensAs test specimens, ta
20、ke from eachlaboratory sampling unit at least three specimens of each fabrictype in accordance with Practice D2905.6.4.1 For simulated sunlight and chlorinated water testing,cut test specimens 125 by 180 mm (5 by 7 in.).6.4.2 Cut specimens representing a broad distribution di-agonally across the wid
21、th of the laboratory sampling unit.Ensure specimens are free of folds, creases, or wrinkles. Avoidgetting oil water, grease, and so forth on the specimens whenhandling. For printed fabrics, ensure that all colors in thepattern are contained in the test specimen.6.4.3 For fabric widths 125 mm (5 in.)
22、 or more, take nospecimen closer than 25 mm (1 in.) from the selvage edge.6.4.4 For fabric widths less than 125 mm (5 in.) use theentire width for specimens.6.4.5 When a garment is the laboratory sampling unit, taketest specimens from various areas of the garment. Avoid takingspecimens along seams.6
23、.4.6 When the required minimum of three specimenscannot be taken from one garment as might be the case withchildrens garments, then take two specimens from each of twogarments, the pair of garments constituting a laboratory sam-pling unit.6.4.7 When a garment is made from different fabrics, atleast
24、three test specimens are required of each fabric thatcovers 10 % or more of the body surface covered by thegarment.7. Procedure7.1 For garments other than swimwear and fabrics intendedto be made into garments other than swimwear, launder 40times using the exposure conditions described in 8.1 and the
25、ntake specimens from these fabrics and expose to 100 AATCCFading Units of simulated sunlight in accordance with theconditions described in 8.2.7.2 For swimwear and fabric intended for swimwear, laun-der 40 times in accordance with the exposure conditionsdescribed in 8.1. Then take specimens from the
26、 launderedfabrics or garments and expose those specimens to 100AATCCFading Units of simulated sunlight in accordance with theconditions described in 8.2 and then to chlorinated water inaccordance with the conditions described in 8.3.7.3 Garments and fabrics intended for use in garments otherthan swi
27、msuits that are sold with the expectation they will notbe laundered (such as disposable or limited-use garments forpesticide application) need only be exposed to simulatedsunlight.8.

28、mperature, agitation cycle inautomatic laundering, drying method and temperature if ma-chine drying, and use of bleach must be those that will beconveyed to the consumer on the care label attached to thefabric/garment. Those conditions should have been determinedby following Guide D3938.8.1.1.1 Care
29、 procedures determined in accordance withGuide D3938 may be modified when it is established that thoseprocedures increase the UV-transmittance of the fabric.8.1.1.2 Follow one of the washing and drying procedures inAATCC 135 or AATCC 172 that matches the care instructionsof the fabric or garment.8.1
30、.2 The specimens to be laundered may be garments,one-yard lengths of fabric, or areas of fabric having minimumdimensions of 380 by 380 mm (15 by 15 in.) or whenapplicable 1450 cm2(225 in.2).8.2 Simulated Sunlight:8.2.1 A xenon-arc lamp must be used which limits the testconditions to those described
31、in AATCC 16 E.8.2.2 For directions for preparing the specimens to beexposed to UV radiation, refer to the test preparation section ofTest Method AATCC 16E noting that only two specimens arerequired and that the specimens are to be cut from thelaundered specimens and omitting the section which refers
