Fully Drawn Yarn Quality Parameters
topic
Fully drawn yarn quality characterisation measures tenacity in centiNewtons per decitex, elongation at break percentage, thermal shrinkage at 180 degrees Celsius, linear density variation by Uster evenness tester, and between-package dye uptake variation by fabric dyeing trials, with Uster statistics providing industry benchmark percentile rankings for evenness and hairiness that indicate competitive quality positioning for each yarn count and type.
Role
Provides the complete quality characterisation required for FDY product specification and process control by measuring the mechanical, thermal, and uniformity properties that determine weaving and knitting performance and the shade uniformity after dyeing, with Uster statistics comparisons against industry benchmarks being the standard method for assessing whether FDY quality meets the requirements of quality-conscious customers for apparel and technical yarn applications.
