Description

(54) МНОГОФИЛАМЕНТЫАЯ ВЫСОКООБЪЕМНАЯ ПОЛИЭФИРНАЯ(54) MULTI-FILAMENT HIGH-VOLUME POLYESTER

НИТЬA THREAD

Изобретение относитс  к The invention relates to

высокообъемным синтетическим нит м, в частности к полиэфирным.high volume synthetic yarn, in particular to polyester.

Известна многофиламентна  высокообъ- емна  полиэфирна  нить, каждый филамент которой имеет чередующиес  участки различного диаметра. Получают эту нить пупутем ее выт гивани  в присутствии агента вызывающего по вление на поверхности филамента трещин.A multifilament high-volume polyester yarn is known, each filament of which has alternating regions of different diameter. This thread is obtained by pulling it out in the presence of a cracking agent on the filament surface.

Недостаток известной нити - недостаточна  стабильность ее размеров.The lack of a known thread - the stability of its size is insufficient.

С целью улучшени  качества нити участки филамента меньшего диаметра имеют степень кристалличности 15-6О%, а участки большего диаметра - 5-25%, при этом максимальный диаметр филамента составл ет 1,01-1,20 минимального диаметра его.In order to improve the quality of the yarn, the areas of the filament of a smaller diameter have a degree of crystallinity of 15-6 O%, while those of a larger diameter - 5-25%, the maximum diameter of the filament being 1.01-1.20 of its minimum diameter.

На чертеже изображена схема получени  предлагаемой нити.The drawing shows the scheme for obtaining the proposed yarn.

Нить 1 из политерефталата этилена сматывают с питающей паковки 2 и выт гивают до 3% между выт жными парами 3 и 4 с одновременным проведением ееThread 1 of ethylene polyterephthalate is wound from the feeding package 2 and pulled up to 3% between the exhaust vapors 3 and 4 while holding it

через ванну 5 с агентом (15%-ный водный раствор этанола при нормальной температуре ), вызьшаюшим растрескивание филамента.through the bath 5 with the agent (15% aqueous solution of ethanol at normal temperature), causing cracking of the filament.

Затем провод т тепловую обработку нити в свободном состо нии с помощью нагревател  6. Степень ослаблени  нити в этой зоне определ ют соотношением скорости роликов 7 и 4.Then, the yarn is heat treated in the free state with the help of the heater 6. The degree of thread loosening in this zone is determined by the ratio of the speed of the rollers 7 and 4.

Обработанную таким образом нить но- гружшот в воду нри 40 °С с постепенным повышением температуры до 10О°С и выдерживают 5 мин. Затем нить высушивают на воздухе в свободном состо нии с последующей обработкой,- гор чим воздухом нри 180°С в течение 5 мин.The thread of the thread thus treated in water at 40 ° C with a gradual increase in temperature to 10 ° C and held for 5 minutes. Then the thread is dried in air in a free state, followed by treatment, with hot air at 180 ° C for 5 minutes.

Втора  теплова  обработка нити может быть также осуществлена непосредственно на машине, а именно в обогреваемой емкости 8, куда нить подают в свободном состо нии, и затем ее принимают на выпу- паковку, установленную на веретене 9.The second heat treatment of the thread can also be carried out directly on the machine, namely in a heated tank 8, where the thread is supplied in a free state, and then it is taken to the outlet mounted on the spindle 9.

Средний диаметр каждого филамента полученной нити 20 мк, при этом степеньThe average diameter of each filament obtained filament 20 microns, the degree

кристалличности тонких участков 20-25%, а утолщенных участков около 1О%.the crystallinity of thin areas is 20-25%, and the thickened areas are about 1O%.

Описьюаема  высокообъемна  нить имеет стабильные размеры и хорошую ваемость.The described high volume thread has stable dimensions and good yield.
