Abstract:
This project is aimed at establishing a National norm for the count
variation of yarns produced in Sri Lankan mills. Owing to , ( a ) its
simplicity (b) its ease of understanding by most mill personnel ( c ) the
possibility of making some international comparisons on National norms
and (d) the ease by which data can be collected , the Percentage Mean
Range CPMR) method of measuring count variation has been used in this project .
The results of this project have indicated that the average count variation of Sri Lankan spun carded cotton yarns are very much greater than ( worse than ) the world average value given under USTER STATISTICS 1982.
