1、Designation: D2102 02 (Reapproved 2012)1Standard Test Method forShrinkage of Textile Fibers (Bundle Test)1This standard is issued under the fixed designation D2102; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r
2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTESection 3, Terminology, was updated editorially in March 2012.1. Scope1.1 This test method covers the measurement of the unre-strai
3、ned shrinkage of a bundle of crimped or uncrimped fibersfrom exposure to some environment, for instance, boilingwater for 15 min.1.1.1 This test method may be used on fibers from tow andfibers removed from spun or continuous filament yarn.NOTE 1For measurement of shrinkage of single fibers, refer to
4、 TestMethod D5104.1.2 The values stated in either inch-pound or SI units are tobe regarded separately as the standard. The values stated ineach system are not exact equivalents, therefore, each systemmust be used independently of the other.1.3 This standard does not purport to address all of thesafe
5、ty 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.

Summary of Test Method4.1 Auniform bundle of conditioned parallel fibers is l

After reconditioning, the bundle length is remea-sured under the same light loading.NOTE 2Due to the v
9、ery high variability of the shrinkage of individualfibers of high shrinkage types, to obtain a reliable average value wouldrequire an excessive number of determinations, each rather tedious. Thebundle method does not give the true average value, but rather a weightedvalue approaching the highest shr
10、inkage fiber in the bundle. Since theweighted value more closely approximates the properties found in a highbulk yarn made from such fibers, the weighted value would seem to bemore appropriate.5. Significance and Use5.1 Limited accuracy in measuring the change in lengthproduces errors in estimating
11、values for shrinkage below 10 %.However, this test is being used for low level shrinkage fibersbecause the results give have been found to give an adequateindication of average shrinkage at the lower levels. The test isnot adequate for determining variability in average shrinkage atlow levels. If th
12、ere are differences of practical significancebetween reported test results for two laboratories (or more),comparative tests should be performed to determine if there isa statistical bias between them, using competent statisticalassistance. As a minimum, use the samples for such a com-parative tests
13、that are as homogeneous as possible, drawn fromthe same lot of material as the samples that resulted in disparateresults during initial testing and randomly assigned in equalnumbers to each laboratory. The test results from the labora-tories involved should be compared using a statistical test forun
14、paired data, a probability level chosen prior to the testingseries. If a bias is found, either its cause must be found andcorrected, or future test results for that material must beadjusted in consideration of the known bias.1This test method is under the jurisdiction of the ASTM Committee D13 onTex
