EFFTCT OF POLYGLYCOL ETHERS ON THE FRICTIONAL PROPERTIES OFHEMISPHERICAL YARN
Abstract
In this study, the effects of polyglycolic ethers on the frictional properties of 22 woolen wool blend yarn with a woolen fiber content of 35% and polyester fiber 65% were studied. The movement of the yarn with external friction is carried out in the direction perpendicular to the vector of relative speed and is determined by the dynamic coefficient of friction. In this case, the occurrence and destruction of bonds between the yarn and the detail of the machine is localized in a thin surface layer. With internal friction, the surface of contact between the fibers in the yarn is continuous and does not depend on the load. Laminar movement of the fibers during friction occurs in the direction of the vector of relative velocity and is determined by the coefficient of tangential resistance. In case of internal friction of the yarn, the deformation covers the whole of its volume, which is reflected in the strength characteristics of the fibrous material. The efficiency of mechanical processing of wool blend yarn can be improved by using polyglycol ethers as a lubricant, which has a positive effect on the friction properties of the fibrous material.
