TEXTILE TESTING II

Object ive of course: Testing can be valuable aid providedthat the instruments and techniques are used effectively. Thissubject provides basic knowledge about general testing

techniques fabric and some advance testing.

UNITIFabric Dimensions:Scope of fabric testingImportance of fabric testing Standards fortests classification of fabric properties, Properties of fabrics asTailor made Fabric dimensions like length, width, fabric weight,threads/inch (Densimeter) crimp measurementsMeasurement ofthicknessTensile Testing of and Fabrics:, classification of Tensile testersand working along with adjustments to suit the material under test
