Description
Изобретение относитс -к области испытани и исследовани свойств извитых текстильных нитей.The invention relates to the field of testing and investigating the properties of crimped textile yarns.
Известен способ определени извитости текстильных нитей, основанный на определении соотношени длин извитого образца до и после его распр млени под действием прилагаемой нагрузки. Дл этого к образцу прилагают распр мл ющую нагрузку, а затем увеличивают ее до полного распр млени .нити, после чего фиксируют удлинение нити и нагрузку.A known method for determining the crimpiness of textile yarns is based on determining the ratio of the lengths of a crimped sample before and after its straightening under the action of the applied load. To do this, a straightening load is applied to the sample, and then it is increased until the strand is fully straightened, after which the elongation of the thread and the load are fixed.
Недостатками -известного способа вл ютс низка точность определени параметров извитости и длительность испытаний по времени. Это обусловлено субъективной оценкой момента перехода образца из извитого состо ни в распр мленное.The disadvantages of the well-known method are the low accuracy of the determination of the parameters of tortuosity and the duration of the test over time. This is due to the subjective assessment of the moment of transition of the sample from the crimped state to the straightened one.
С целью повышени точности и скорости определени параметров извитости по предлагаемому способу ультразвуковые импульсы посылают непрерывно по испытываемому образцу , закрепленному -между источником и приемником этих импульсов, с постепенным увеличеиием распр мл ющей нагрузки и момент -полного распр млени фиксируют -по максимальной амплитуде ультразвуковых импульсов, снимаемых с приемника контрольно-измерительным прибором, с одновременной фиксацией распр мл ющей нагрузки и удлинени образца .In order to improve the accuracy and speed of determining the parameters of tortuosity according to the proposed method, ultrasonic pulses are sent continuously over the test sample, fixed - between the source and receiver of these pulses, with a gradual increase in the spreading load and the instant of full spread is fixed - at the maximum amplitude of ultrasonic pulses removed from the receiver with a measuring instrument, with simultaneous fixation of the spreading load and sample elongation.
Предмет изобретени Subject invention
Способ определени извитости текстильных нитей, заключающийс в том, что испытуемый образец закрепл ют IB зажимах, прикладывают распр мл ющую нагрузку, регистрируют момент полного распр млени образца и фиксируют приложенную нагрузку и удлинение образца, по которым суд т о извитости нити, отличающийс тем, что, с целью повышени точности и скорости определени параметров извитости, момент поллого распр млени испытуемого образца определ ют путем прозвучивани образца ультразвуковыми импульсами, причем момент полного распр млени определ ют по их максимальной амплитуде.A method for determining the crimpiness of textile yarns, which consists in fixing the test specimen with IB clamps, applying a straightening load, registering the moment of full straightening of the specimen, and fixing the applied load and elongation of the specimen, according to which In order to improve the accuracy and speed of determining the crimp parameters, the moment of polling of the test sample is determined by sounding the sample with ultrasonic pulses, and dissolved limit their maximum amplitude.
