The research of tensile properties of core-spun high shrink yarn

When using clothes, the material undergoes different types of deformation: stretching, compression, bending, torsion, the value of which is much less than the breaking one. Small in size, these loads, alternating with unloading and rest, weaken the structure of the material. Work has been done to determine the effect of the tension of the complex high - shrinkable thread and the processing temperature on the deformation characteristics of the combined high-shrinkable threads. Regression models of the interrelation of the analyzed factors on the unbreaking single - cycle characteristics of a combined thread are developed. The optimal modes of the process of forming the thread and its heat treatment were chosen to obtain a combined high - shrinkable thread with a minimum value of the irreversible part of the deformation.
