8、forcecauses yarns to shift distorting the original symmetry of theweave is taken as a measure of ease of yarn distortion in thefabric.The degree of distortion is reported in terms of thewidest opening,measured in hundredths of an inch.5.Significance and Use5.1 This test method is considered satisfac
9、tory for accep-tance testing of commercial shipments because current esti-mates of between-laboratory precision are acceptable and themethod has been used extensively in the trade for acceptancetesting.5.2 In cases of dispute,the statistical bias,if any,betweenthe laboratory of the purchaser and the
10、 laboratory of the sellershould be determined,with each comparison being based ontesting randomized specimens from one sample of fabric.5.3 This test method is used as an indication of the propen-sity of yarns to shift or distort in a fabric.Such distortions areobjectionable due to the resulting cha
11、nges in appearance.These appearance changes are sometimes referred to as“fingermarks”or“shift marks.”5.4 It is recommended that fabrics be tested in their originalcondition and also after laundering or drycleaning,or both,depending upon the intended use of the material.1This test method is under the

15、s1 6.Apparatus6.1 Fabric Shift Tester5,as shown in Fig.1,including:6.1.1 Cylindrical Rubber Friction Drums,consisting of apair of rubber drums mounted one above the other on the testerin such a way that the specimen may be inserted between theirtwo circular contacting surfaces.Each drum shall be 19
16、mm(0.75 in.)in diameter and have a Shore Durometer hardness of55 to 60(A scale).The lower drum shall be 51 mm(2 in.)inlength,fastened to the platform of the apparatus.Facilities shallbe provided for rotation of the drums in the mounting framebetween tests.The upper drum shall be 25 mm(1 in.)in length,have the same provisions for rotation as the lower one,andshall be so mounted that a total force of 4.5 to 18 N(1 to 4 lbf)can be exerted upon the specimen by means of a lever arm andmovable weight.
