Description
Известен способ обработки волокон из поливинилового спирта, включающий выт жку и термическую обработку. При этом способе освобожденное от растворител волокно сначала выт гивают, а затем подвергают термической обработке.A method of treating fibers from polyvinyl alcohol is known, which includes stretching and heat treatment. In this method, the solvent-free fiber is first drawn out and then subjected to heat treatment.
По описываемому способу освобожденное от растворител волокно подвергают выт жке нрп температуре 180-230°, производимой в пара.х декагидронафталина или в парах бензолового спирта, что позвол ет осуществл ть выт жки за небольшие промежутки времени и проводить процесс с больщой скоростью.According to the described method, the solvent-free fiber is subjected to an LPC temperature of 180-230 °, produced in parax x decahydronaphthalene or benzene alcohol vapor, which allows stretching for short periods of time and carrying out the process at a high rate.
Осуществление способа производитс , например, следующим образом .The implementation of the method is, for example, as follows.
Нить из поливинилового спирта, под которым подразумеваетс синтетический полимер, содержащий не менее 50% винилового спирта (-СНз-СНОН-), с титром 145 денье, из 20 элементарных волокон, с круткой 50 витков на метр, полностью высущенна , пропускаетс через камеру с парами декагидронафталина, которые могут быть перегреты до 230°. При этом процесс, при выт жке нити 6: 1, проходит со скоростью 150 Л1/ЛШН при длительности нахождени в парах в течение 0,28 сек.Polyvinyl alcohol filament, by which is meant a synthetic polymer containing not less than 50% vinyl alcohol (-CH3-SNON-), with a denier of 145 denier, from 20 elementary fibers, with a twist of 50 turns per meter, completely drained decahydronaphthalene vapors, which can be overheated up to 230 °. In this process, when the filament is 6: 1, it runs at a speed of 150 L1 / LShN with a duration of being in pairs for 0.28 seconds.
Аналогично этому выт жка нити производитс также в парах бензолового спирта при 205°; скорость при выт жке 6,5 : 1 равна 160 м/мин.Similarly, yarn stretching is also carried out in benzene alcohol vapor at 205 °; 6.5: 1 stretching speed is 160 m / min.
