Description
Изобретение относитс к способу определени технологических параметров текстильных материалов, а именно к способу олреде .лени Крутки движущихс гибких длинномерных материалов, особенно при переработке филаментных нитей на одноп,роцессных машинах .The invention relates to a method for determining the technological parameters of textile materials, namely to the method of olredine. Twists of moving flexible lengthy materials, especially when processing filament yarns on single process machines.
Известен способ определени числа кручений на единицу длины перемещающихс с посто нной скоростью гибких длинномерных материалов, заключающийс в том, что число витков определ ют по числу оборотов диска, контактирующего с материалом.A known method for determining the number of twists per unit length of flexible flexible materials moving at a constant speed is that the number of turns is determined by the number of revolutions of the disk in contact with the material.
Легк1ий диск, расположенный под определенным углом к оси испытуемого материала, например нити, под действием сил трени вращаетс . По числу оборотов диска и его размеру определ ют число витков нити.A light disk located at a certain angle to the axis of the test material, such as a thread, is rotated by the action of friction forces. The number of turns of the thread is determined by the number of revolutions of the disk and its size.
Однако -при использовании этого принципа нарушаетс правильность протекани технологического процесса и способ не дает высокой точности измерени .However, when using this principle, the correctness of the technological process is violated and the method does not give a high measurement accuracy.
Цель изобретени - повысить точность измерени . Дл этого на нить направл етс пучок пульсирующего луча света стробоскопа с частотой, равной или кратной частоте движущейс нити и по остановившемус изображению определ ют угол наклона филамента или стренги к оси нити.The purpose of the invention is to improve the measurement accuracy. For this, a pulsed light beam of a stroboscope with a frequency equal to or a multiple of the frequency of the moving thread is directed to the filament and the angle of the filament or strand to the filament axis is determined from the stopped image.
Объектом измерени вл етс филаментна нить, участвующа одновременно в трех движени Х: вокруг своей оси, поступательном перемещении вдоль оси и баллонировании.The object of measurement is a filament thread participating simultaneously in three movements X: around its axis, translational movement along the axis and ballooning.
Угол наклона винтовой линии филамента или стренги характеризует величину крутки на данном участке нити.The angle of inclination of the helix of the filament or strand characterizes the amount of twist on a given portion of the thread.
Предлагаемый способ по сн етс чертежом , .лде: 1 - испытуема нить, 2 - стробоскоп , 3 - источник световых колебаний, 4 - крутильный орган, 5 - питающа пара, 6 - выпускна пара.The proposed method is illustrated in the drawing, lde: 1 — the thread to be tested, 2 — the stroboscope, 3 — the source of light oscillations, 4 — the torsional organ, 5 — the feeding pair, 6 — the discharge pair.
Дл осуществлени способа на теремещаемую с посто нной скоростью от питающейIn order to carry out the process of moving at a constant speed from the feed
пары нить направл ют пульсирующий луч света и подбирают частоту пульсации, равную или кратную частоте движущейс нити. По полученному изображению определ ют угол наклона ее филамента или стренги к оси нитиthe yarn pairs direct a pulsed light beam and select a pulsation frequency equal to or a multiple of the moving yarn frequency. The image obtained is used to determine the angle of inclination of its filament or strand to the axis of the thread.
и число витков, соответствующее частоте пульсации луча света стробоскопа.and the number of turns corresponding to the frequency of pulsation of the strobe light beam.
