Properties of textile materials based on polifen fibres

Conclusions In processing man-made fibres in pure form or in mixtures with natural fibres, it is recommended to reduce the intensity of carding by increasing the separation between working parts of the carding machines and reducing their speed.To eliminate a large amount of fly in carding, one should carry out the technological preparation of the Polifen and wool fibre using heating and picking machines.The materials have a low air permeability and high efficiency when used as filtering elements.Translated from Khimicheskie Volokna, No. 4, pp. 41–42, July–August, 1986.

Improving the thermal-shock resistance of corundum ceramic

Conclusions We have studied the effect of coarse-grained additives of electrocorundum, sintered mullite, SiC, and electrosmelted ZrO₂ on the thermal-shock resistance of a corundum ceramic obtained from a mixture of technical alumina and glass-forming oxides. New ceramic materials have been obtained with a higher thermal-shock resistance, a lower open porosity, and adequate strength. The materials can be used in the manufacture of articles to be operated under conditions of stringent thermal loading.Translated from Ogneupory, No. 2, pp. 44–48, February, 1982.
