ABSTRACT
Quality of yarn is dictated by the quality of fibers used in the production course that is the extent of contribution arises from fiber quality attribute in yarn engineering. This statement is true irrespective of production technology; conventional slow speed or modern high speed as well as spinning techniques, viz; classical ring spinning or unconventional rotor, dref or air jet spinning employed for the purpose. Thereby success involved in meeting consumer’s demand is mainly attributed to right start or else way right selection of raw material. But this requires detailed knowledge about fiber parameters and they should be measured with due precision. Different test methods are in use, starting from traditional to modern times for this purpose. However, each of them has associated advantages and disadvantages. An attempt is made to provide a brief mention about these techniques along with various specifications used in the course of measure. This can help spinner in sketching out the several relationship as per kind of technology available at his end.
