Abstract

Riešenie sa týká sposobu preparovania polypropylénových vláken, s výhodou vyšších dížkových hmotností pri ich kontinuálnej výrobě. Podstata spočívá v tom, že vlákna vznikajúce pod zvlákňovacou hubicou s teplotou vyššou ako 80 °C vstupujú do vane s vodnou emulziou, ktorej teplota je od 20 do 60 °C, zloženej z minimálně 12 g . I-1 látky etoxilovanej kyseliny olejovej, alebo jej zmesi s etanolamínovou solou sulfonovaného mastného alkoholu Cio—Cle v úlohe tenzidu a aspoň 8 g. I"* 1 etoxilovaného ricínového oleja. Vlákna vystupujú z vane s teplotou menšou ako 80 °C, pričom na ich povrchu je vytvořená vrstva emulzie, ktorá tvoří minimálně 5 °/o hmotnosti vláken.The solution concerns the method of preparation of polypropylene fibers, with the advantage of higher linear weights during their continuous production. The essence consists in the fact that the fibers formed under the spinning nozzle with a temperature higher than 80 °C enter a bath with an aqueous emulsion, the temperature of which is from 20 to 60 °C, composed of at least 12 g. I-1 substance of ethoxylated oleic acid, or its mixture with the ethanolamine salt of sulfonated fatty alcohol Cio-Cle in the role of surfactant and at least 8 g. I"* 1 of ethoxylated castor oil. The fibers emerge from the bath with a temperature of less than 80 °C, while a layer of emulsion is formed on their surface, which makes up at least 5 °/o of the weight of the fibers.
