This paper presents the results of observation and measurements of the wear of a spindle-neck coating made of the aluminium alloy AlCu4Mg1 of an anti-balloon crown of a PG-7A ring-spinning frame. Eva...
The value of twist is an essential yarn property for a spinner. This paper presents an analysis of the influence of changes in the yarn twist value on yarn tension and the stability of yarn formatio...
Nowadayspolyamides have become essential in fibre production for textiles and technical uses. However, such applications require extremely high strength parameters as well as excellent dimensional sta...
The aim of this study was to evaluate the energy consumption, in general, for ring type yarn manufacturing systems and to examine the energy consumption in a chosen spinning mill by considering the av...
This paper presents the results of our investigations into the wear of steel guides by yarn blends. The guides were made from steel 50SiCr4 which was hardened and tempered to a hardness value of 400 H...
The hairiness of a yarn can be defined as the total number or total length of the fibres which leave from the unit yarn’s surface. Yarn hairiness is formed by surface fibre edges which leave the yarn ...
The technological characteristic of the twisting-and-winding system of a ring spinning frame was determined on the basis of a model of the system’s dynamics (including its disturbances), which was for...
