1、Designation: D3692 89 (Reapproved 2012)Standard Practice forSelection of Zippers for Care-Labeled Apparel andHousehold Furnishings1This standard is issued under the fixed designation D3692; the number immediately following the designation indicates the year oforiginal adoption or, in the case of rev
2、ision, 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 provides guidelines to the manufacturerfor the selection of zippers to be used in gar
3、ments andhousehold furnishings that have care labels. The use of thispractice will facilitate the selection of a zipper compatible withthe end-item requirements. In the absence of complete knowl-edge of end-item characteristics, it is not possible to stipulatespecific universal characteristics for a
4、 care label. Thereforefollowing initial selection, the chosen zipper should be testedin a prototype item to confirm its suitability. Zipper propertiesto be considered are those that may, following refurbishing, bethe ones likely to adversely affect the continued use andenjoyment of the item in which
5、 the zipper is installed.1.2 The product characteristics evaluated by this practiceare shrinkage, colorfastness, and ironing deformation.NOTE 1Test methods of interest include Test Method D2052, TestMethod D2053, Test Method D2054, Test Method D2057, Test MethodD2060,1.3 This standard does not purpo

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.

Significance and Use4.1 This practice is useful for the selection of zippers thatwill be compatible with items to be care labeled.4.2 This practice is useful as a guide for the selection of testmethods to evaluate zipper properties that are relevant tocar
10、e-labeled items.5. General5.1 It is advisable that zippers be closed when items inwhich they are installed are being laundered or dry cleaned.6. Shrinkage6.1 Excessive differential shrinkage between the zipper andthe material into which it is installed can impair item appear-ance and the functioning
11、 of the zipper. To avoid problems,zippers need to have compatible but not necessarily equalshrinkage to that of the fabric. The acceptable shrinkagedifferential may vary depending upon fabric weight and itemconstruction. The fabric weight, method of zipper installation,and zipper shrinkage should be
12、 considered in determining howmuch shrinkage differential is acceptable.6.2 Zipper shrinkage compatibility cannot be specified inabsolute terms, therefore, it is essential that a preliminarymock-up representing the planned zipper installation be con-structed and subjected to the proposed care refurb
13、ishingprocedure to determine the zipper shrinkage compatibility.1This practice is under the jurisdiction ofASTM Committee D13 on Textiles andis the direct responsibility of Subcommittee D13.54 on Subassemblies. This practicewas developed in cooperation with the Slide Fastener Association, Inc.Curren

16、e selecting of a compatible zipper basedon shrinkage.6.3.1 Lightweight MaterialsLightweight materials requirezippers having the most compatible shrinkage. For materials upto 0.27 kg/m2(8 oz/yd2), a differential shrinkage betweenzipper and fabric of approximately 1 % has been found to besatisfactory.
17、6.3.2 Heavyweight MaterialsMaterials over 0.27 kg/m2(8oz/yd2) do not always require low differential shrinkage.6.3.2.1 If the textile material shrinks less than the zipper, thedifferential shrinkage may exceed 1 %. Zipper shrinkages ashigh as 4 % have been found satisfactory depending upon thetextil
18、e material involved.6.3.2.2 If the textile material shrinks more than the zipper, amaximum differential of approximately 1 % is probablyneeded.7. Colorfastness7.1 Matching Textile MaterialWhen a zipper of matchingcolor to the textile material is to be installed, colorfastness maynot be critical. For
19、 initial evaluation purposes, it may beassumed that any commonly accepted home or commercialwashing procedure will not cause objectionable zipper colorloss or staining of item in which installed.7.2 Contrasting Textile MaterialThe general colorfast-ness properties of zippers are predicated on the as
20、sumption thatthe zipper will be installed in material of like color. If suchzippers are utilized in contrast-colored material, it is necessaryto include on the care label instructions to machine drypromptly following laundering and to avoid soaking, handwashing, the use of low-water levels in launde
21、ring, and linedrying. To avoid such undesirable labeling, the zipper suppliershould be contacted and advised of the intended use so that azipper with suitable colorfastness properties will be furnishedfor installation in a contrast-colored, washable material. Forspecific colors and by arrangement wi
22、th the zipper supplier, itis possible to obtain zippers whose colorfastness properties willpreclude the need for special care label instructions for thezipper.7.2.1 If the end-item with a contrasting color zipper is to becare labeled “Dry Clean Only,” then commercially furnishedzippers should be fou
23、nd to be colorfast.8. Ironing Deformation8.1 When zippers are to be used in items not requiringironing as a refurbishing procedure, there is no need for specialcare labeling.8.2 When zippers are to be used in items requiring ironing,the following must be observed:8.2.1 If the zipper is installed so
24、that it will not come intocontact with the iron during ironing, no special care labeling isrequired.8.2.2 If the zipper is installed so that it can come intocontact with the iron, the following is recommended:8.2.2.1 Metal-Element ZippersWhen the zipper is madeon cotton tapes, no special care instru
25、ctions are necessary.When the zipper is made on tapes containing synthetics, itshould be used only on items to be care-labeled “use cooliron.”8.2.2.2 Plastic-Element ZippersPlastic-element zippersshould be used only on items to be care-labeled “use cooliron.”9.
