EFFECT OF TECHNOLOGICAL WINDING PARAMETERS ON YARN PACKAGE DENSITY

Abstract

This paper presents the experimental results on the simultaneous influence
of four technological parameters during winding process: the winding speed (Z1),
the load on the friction discs of the yarn tensioner (Z2), the distance between the
bobbin and the yarn guide (Z3) and the pressure of package on the grooved drum
(Z4) on the winding density of conical yarn package. By using the orthogonal
experimental, with the help of the software Excel 2019 and Design Expert 11, the
mathematical models describing the relationships between four technological
parameters and the winding density of the yarn packages were establised when
the winding three ring yarn types: carded Ne 31/1 CVCD, combed Ne 30/1 CVCM,
combed Ne 30/1 COCM. The research result is the scientific basis for selecting the
optimal technological parameters to achieve the winding density when winding
of three types of yarn respectively: 0.534g/cm3
, 0.519g/cm3
, 0.501g/cm3
on
request or predict the winding density before winding with the option of choosing
the defined technological parameters.
