Abstract

The method of production of fiber guiding parts is intended for textile machines. The essence of the method consists in the fact that the guiding parts of the fibers, isostatically pressed from a mixture of up to 95 parts of titanium dioxide and 5 parts of aluminum, silicon and zinc oxide, are dried at a temperature of up to 1270 K, chipped and with tolerance to volume changes, annealed for 1 hour in a water atmosphere at a temperature of 1320 to 1520 K and ioh the surface is ground and polished. The method of production of fiber guiding parts can be used in textile engineering.

BACKGROUND OF THE INVENTION The present invention relates to a method for producing fiber guide guides. Fiber guide parts of textile machine equipment through which filaments are fed during their mass production · In doing so, individual types of fibers require that their guide parts have a high hardness and, consequently, abrasion resistance, raiimine porosity and surface roughness as well as heat and elec- tricity conductivity, chemical resistance and the ability to produce in the required shape.

Up to now, fiber guide parts are made of different metallic or ceramic materials, e.g. titanium dioxide, eventually other oxides · Normally, pressurize and anneal at high temperatures with Air access. For example, there is a known method of producing fiber guide elements of pure oxidutite-based ceramic material with a hardness of 10000 HVm, a specific gravity of 3.87 g / cm, a porosity of 6 to 8%, and a surface roughness of Ra = 1.85 µm aR. Um. The disadvantage of these methods of manufacturing mesh guides is that the components have a relatively short lifetime, the dark result of considerable porosity, the low surface hardness and the associated low abrasion resistance at minimal surface roughness

The above-mentioned drawbacks are avoided by the method of producing filament guide webs made on the basis of titanium dioxide, aluminum, silicon and zinc isostatic by pressing according to the invention, wherein the conductive fiber isostatic is pressed from a mixture of up to 95 parts titanium dioxide and 5 parts alumina, silica and zinc sulfide at a temperature of up to 1270 k;
