Methods to improve hackles in the production of quality yarn

Abstract

Abstract The article covers the analysis of work members and mechanisms of hackles, substantiation of technical parameters and modes of operation in order to improve the quality of yarn, to eliminate thread irregularities, to reduce thread breakage and defects by changing the hackling segments and supply table spacing. The work members of the hackles, the traction forces of the roving and the hackle, as well as the productivity of the machine are theoretically determined. The hackling level indicates the thickness of the fiber layer on the surface of the main drum, or how many fibers fit into a single headset tooth. By varying the spacing between the receiving drum and the supply table, the fibers are better hackled, the degree of hackling increases - the higher the quality of the hackle and the effect on the quality of the roving has been determined theoretically and experimentally.
