Description

Важнейшей характеристикой волокнистых материалов  вл етс  их средн   длина волокна.The most important characteristic of fibrous materials is their average fiber length.

Известный микроскопический способ определени  средней длины волокна весьма длителен, недостаточно точен и требует высокой квалификации работника.The known microscopic method of determining the average fiber length is very long, not accurate enough and requires highly skilled workers.

Предлагаемый способ определени  средней длины волокна имеет целью устранить указанные недостатки и заключаетс  в том, что в жидкую массу, составленную из размешанной в жидкости сухой пробы испытываемого волокна, погружа}от решетчатую рамку с р дом нат нутых проволок или нитей, а затем через определепньп промежуток времени извлекают рамку, взвешивают и определ ют среднюю длину волокна по весу волокон, оставшихс  на рамке после извлечени  ее из жидкости.The proposed method of determining the average fiber length is aimed at eliminating the indicated drawbacks and consists in immersing a grated frame with a series of tensioned wires or threads in a liquid sample made up of a dry sample mixed in a liquid, and then after some time time, a frame is removed, weighed, and the average fiber length by weight of the fibers remaining on the frame after removing it from the liquid is determined.

ОпределеР1ие средней длины волокна, согласно изобретению, производитс  следующим образом.The average fiber length in accordance with the invention is determined as follows.

На двух чертежах приведен общи:: вид испытуемого прибора.The two drawings show the general :: view of the device under test.

6 г абсолютно сухого волокна размешивают в двух литрах воды (концентраци  3 г на 1л) и полученную массу выливают в сосуд / (фиг. 1), на дно которого положена рамка 2 с р дом нат нутых на ней проволок или нитей (фиг. 2). Далее рамку 2 при помощи стержн  3, вынимают из сосуда / и навешивают на крючок 4 коромысла весов , при этом указатель 5 весов предварительно устанавливают при помощи установочных винтов на нулевое деление шкалы 6. Отсчет показаний па шкале 6 прибора делают через 2 мин после стекани  избыточной воды с волокон, оставшихс  на рамке после извлечени  ее из сосуда /.6 g of absolutely dry fiber are stirred in two liters of water (concentration 3 g per 1 l) and the resulting mass is poured into a vessel / (Fig. 1), on the bottom of which a frame 2 is laid with a number of wires or threads tightened on it (Fig. 2 ). Next, frame 2 using the rod 3, is removed from the vessel / and hung on the hook 4 of the balance beam, while the pointer 5 weights are pre-set using the set screws on the zero division of the scale 6. The readings on the scale 6 of the device are done 2 minutes after draining excess water from the fibers remaining on the frame after removing it from the vessel.

Показани  на приборе веса влажного волокна, выран енного в граммах, перевод т на диаграмме или таблице в показани  средней длины волокна.The readings on the instrument of the weight of the wet fiber cut out in grams are converted on the chart or table to the readings of the average fiber length.

Способ определени  средпей длины волокна волокнистых материалов , отличающийс  тем, что в жидкую массу, составленную из размешанной в определенном объеме жидкости отвешенной пробы сухого испытываемого волокна, погружают решетчатую рамку с р дом нат нутых проволок или нитей, а затем через определенный промежуток времени извлекают рамку и взвешивают, с целью определени  средней длины волокна по весу волокон, оставшихс  на рамке носле ее извлечени  из жидкости.The method of determining fiber lengths of fibrous materials, characterized in that a lattice frame with a series of tensioned wires or filaments is immersed in a liquid mass composed of a weighed sample of a dry test fiber, and then after a certain period of time a frame is extracted and weighed to determine the average fiber length by weight of the fibers remaining on the frame when it is removed from the liquid.
