式中：T₁——拉伸1次后的弹性回复率，%;T2o——拉伸20次后的弹性回复率，%;S,——拉伸1次后的塑性变形率，%;S2—拉伸20次后的塑性变形率，%。T/CTES1069—20243测定结果以3次有效结果的平均值表示，修约至0.1%。如果试样滑移或断裂，舍弃试验结果，另加试样以得到3个正常值。如果所有的试验结果都是断裂，或得不到3个正常值，应报告单值并在试验报告中说明。9弹性保持性等级评价机织弹性制服面料(经或纬向)的弹性保持性分为3级，见表1。表1等级评价A级B级C级定伸长10%弹性回复变化率≤4%22%塑性变形变化率≤60%450%试验报告应包括下述内容：b)试样的描述、试样数量；c)试验条件；d)试验结果；e)任何偏离本文件的细节4机织制服面料弹性保持性试验方法5T/CTES1069—2024ForewordThisdocumentisdraftedinaccordancewiththerulesestablishedintheGB/T1.1—2020Directivesforstandardization—Part1:Structureanddraftingofstandards.ThisdocumentisproposedbytheStandardizationWorkingCommitteeoftheChinaTextileEngineer-ingSociety.Theissuingbodyofthisdocumentisnotresponsiblefortheidentificationofpatents.ThisThisdocumentisunderthejurisdictionofChinaTextleEngineeringSociety.6T/CTES1069—2024TestmethodofelasticityretentionforwovenuniformfabricsThisdocumentgivesthetestmethodsandevaluationindexesfortheelasticityretentionofwovenuniformfabrics.Thisdocumentisapplicabletowoolenwovenelasticuniformfabrics,andotherwovenelasticfabricscanaisobereferredto.Thecontentsofthefoliowingdocumentsconstitutetheindispensableprovisionsofthisdocumentthroughthenormativereferenceswithinthetext.Amongthem,iftheciteddocumentisdated,onlytheversioncorrespondingtothedateappliestothisdocument.Iftheciteddocumentisnotdated,thelatestversion(includingallthemodlficationsheets)appliestothisdocument.GB/T3291.3,Textiles—Termsoftextilematerialpropertiesandtest—Part3:GeneralGB/T3923.1,Textiles—Tensilepropertiesoffabrics—Part1:DeterminationofmaximumforceandelongationatmaximumforceusingthestripmethodGB/T6529,Textiles—StandardatmospheresforconditioningandtestingFZ/T01034—2008,Textiles—Testmethodofthetensileelasticityforwovenfabrics3TermsanddefinitionsThetermsanddefinitionsdefinedinGB/T3291.3,GB/T3923.1.FZ/T01034—2008,alongwiththefollowingtermsanddefinitions,areapplicabletothisdocument.3.1woolenshellfabricsforuniformAllwoolenfabricsandfabricswovenwithwoolen-typechemicalfiborsspunpurelyorblendedwithT/CTES1069—202488Teststeps8.1Instrumentsetup8.1.1Calibratethezeropositionandtensionoftheinstrumentandrecordingdevicebeforethetest.8.1.2Calibratethespacinglengthof200mmandensuretheclampsarealignedandparalleltoeachother.8.1.3Thetensilespeedis100mm/min.8.2ClampingofspecimensClampingspecimeniscarriedoutaccordingtotherequirementsspecifiedin8.2.1ofFZ/T01034一2008andselectedwithreferencetothevalueofpreloadedtensionofelasticwovenfabrics.8.3Determinationandcalculation8.3.1Determinationofconstantelongationtensileelasticity8.3.1.1Selecttheconstantelongationaccordingtotherequirementsoftheproduct,10%isrecom-mended.8.3.1.2Testandcalculateaccordingto8.3.5ofFZ/T01034—2008.8,3.2Determinationofelasticityretention8.3.2.1Selecttheconstantelongationaccordingtotheproductrequirements,10%isrecommen-ded.8.3.2.2Thetensionstoppingtimeis1min,therecoverytimeis3min,andthenumberofcyclesis20times.8.3.2.3Repeatthestretching20timesaccordingto8.3.1.3;thenstretchthespecimenatthesamespeedandreadthelengthofthespecimencorrespondingtothepre-tension.8.3.2.4Calculatetherateofelasticrecoveryandplasticdeformationofthespecimeninrepeatedstretchingaccordingtotest8.3.1.7wool.3.2rateofchangeoftheelasticrecovery3.3rateofchangeofplasticdeformationThepercentagedifferenceinthefabric'splasticdeformationratebetwveenaftermultiplerepetitionsofconstantelongationandasinglestretch,relativetotheplastiedeformationrateofasingiestretch.Byusingrepeated/stretchingunderconstantelongation,boththechangesintheelasticrecoveryrateandplasticdeformationrateofthetestedfalbricaremeasuredandcalculated.Theelasticretentionofthefabricisevaluatedbysharactenizingthechangesintheelasticrecoveryrateandplasticdeforma-tionrate.5Equipment5.1Equalelongatior(CRE)tester;ThisshouidcomplywiththerequirementsofG5B/T3923.1,en-surethattheforceachieve1%oftheindicatedvalue,becapableofconstantelongationandfixedforcestretching,andbeequippedwitharecordingdevice.5.2Apparatusforcuttingspecimens6SamplingAccordingtotheprovisionsofGB/T3923.1.Eachsamplemusthaveatleastthreespecimenscutintheelasticdirection(warporweft).7Moistureandtestenvironment7.1Pre-conditioningandhumidificationofthespecimeninaccordancewiththeprovisionsofGB/T6529.T/CTES1069—202498.3.2.5Calculatetherateofchangeofelasticrecovery,Teo(%)andtherateofchangeofplasticdeformation,Soe(%)accordingtoequations(1)and(2)respectively.T1—Elasticrecoveryrateafterasinglestretch,%;T20—Elasticrecoveryafterstretching20tímes,%;S,—Plasticdeformationrateafterasinglestretch,%;S20一Plasticdeformationrateafterstretching20times,%.Theresultsareexpressedastheaverageof3validresults,trimmedto0.1%.8.3.3SlippageorbreakageIfthespecimenslipsorbreaks,discardthetestresultandaddanotherspecimentoobtain3validvalues.Ifalltestsresultinbreakage,orif3validvaluescouldnotbeobtained,reportasinglevalueandstatethisinthetestreport.9EvaluationofelasticityretentionlevelTheelastiityretentionofwovenelasticunifomfabrics(warporweftdirection)iscategorizedintoTable1—Grade
