The goal of this research work was an exhaustive analysis of the influence of carding units (double and triple ones) on the quality of wool yarn. Certain factors that greatly influence the inequality of woolen yarn were analysed. A description of measurement methods used for the determination of the inequality of linear density are presented in this article. The technological parameters of double and triple carded units, as well as their influence on the production of woollen yarns is discussed. For measurement of differences in the inequalities of yarns of the same linear density but produced form different carding units an Uster testing set was used. The influence of three carding units of different technological parameters on the formation of periodic irregularity in the yarn linear density was exhaustively analysed. [ABSTRACT FROM AUTHOR] |
