Designation:D633798(Reapproved 2013)Standard Practice forPhysical Characterization of Woven Paint ApplicatorFabrics1This standard is issued under the fixed designation D6337;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of 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 the dimensions,terminology,andcharacteristics generally considered of importance to thosedealing with woven paint applicator fabrics and describesmethods for determining these parameters.This practice is notmeant to be a definitive analytical method to deformulatewoven fabrics.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD1776 Practice for Conditioning and Testing TextilesD1777 Test Method for Thickness of Textile MaterialsD3774 Test Method for Width of Textile FabricD3775 Test Method for Warp(End)and Filling(Pick)Countof Woven FabricsD3776 Test Methods for Mass Per Unit Area(Weight)ofFabric3.Terminology3.1 Definitions:3.1.1 Several terms in this practice are defined in accor-dance with Terminology D123.3.2 Definitions of Terms Specific to This Standard:3.2.1 backcoating,na resin coating that is usually appliedto the back of a fabric and heat cured to enhance its stability.3.2.2 backing,na set of warp yarns or ends of definedcomposition that help create the base of a fabric that runs thelength of the fabric(see Fig.1).3.2.3 case of fabric,na box of cloth,ready for shipping,usually consisting of slit reels.3.2.4 dyelot,na specific quantity that is processed to-gether and can be comparatively ranked within or among otherdyelots.3.2.5 end,none warp yarn(see Fig.1).3.2.6 fiber,nan individual strand or filament of finite orcontinuous length that may be of a natural or synthetic origin.3.2.7 filling,nan individual yarn of defined compositionthat interlaces with warp ends at right angles in a woven fabricto help form the base of a pile fabric(see Fig.1).3.2.8 laboratory sample,na sample from each case offabric for acceptance testing.3.2.9 lot sample,na sample for acceptance testing con-sisting of a random number of dyelots as directed in agreementbetween purchaser and supplier.3.2.10 pick,none filling yarn(see Fig.1).3.2.11 pick glass,nan instrument with a magnifying lensand a set viewing field of one square inch used to identifyconstruction(see Fig.2).3.2.12 pile,nan additional set of warp yarns or ends ofdefined composition that are introduced into a pile fabric tomake cut or uncut loops on the surface that are approximatelyperpendicular to the plane of the backing and filling(see Fig.1).3.2.13 pile fabric,na three-dimensional cloth with inter-lacing at right angles of three systems of yarn as warp,fill,andpile.3.2.13.1 DiscussionPile fabrics have a fur-like face thatcan consist of cut or uncut loops.3.2.14 pile fabric composition,nthe total make-up of thefabric,being either natural or synthetic,or a combination.1This practice is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.61 on Paint Application Tools.Current edition approved Nov.1,2013.Published November 2013.Originallyapproved in 1998.Last previous edition approved in 2007 as D6337 98(2007).DOI:10.1520/D6337-98R13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.15 pile height micrometer,na thickness testinginstrument,referenced in Test Method D1777.3.2.15.1 DiscussionIt consists of 4 in.(102 mm)diameterpresser foot controlled by a lever,a gage with readings to thenearest 0.001 in.(0.025 mm)and a horseshoe-shaped handlethat will measure 6 in.(152.4 mm)into the body of the fabric(see Fig.3).3.2.16 pile tuft density,nthe quantity of pile per unit areaas stated in pile tufts per square inch.3.2.17 reel,na specified length of slit goods rolled to-gether as one unit.3.2.18 shearable pile,nthe pile tufts above the backingthat can be removed with shear clippers.3.2.19 slitting,na means of cutting the full width of fabricinto longitudinal strips.3.2.20 slit
