Изобретение относитс к области испытани свойств материалов, в частг ности испытани прочности лицевого сло меховых овчин, и может быть использовано в меховой промышленности и системе заготовок шубно-мехового сырь .The invention relates to the field of testing the properties of materials, in particular, testing the strength of the face layer of fur sheepskins, and can be used in the fur industry and the system of blanks of fur-fur raw materials.
Известен способ испытани лицевого сло меховых овчин на прочность к раст жению, заключающийс в раст жении образца, измерени раст гивающего усили и оценке по нему прочности лицевого сло в момент по влени в нем трещин 1.A known method for testing the tensile strength of a sheepskin sheepskin layer consists in stretching a sample, measuring a tensile force and evaluating the strength of the face layer thereon at the moment of cracking in it 1.
Однако и этот способ неприемлем дл испытани лицевого сло парных и консервированных меховых овчин, т.к. разрыв кожевой ткани будет также происходить без предварительного по влени трещины лицевого сло . Ве-личина раст гивающего усили , при которой происходит разрыв образца, характеризует прочность всей кожевой ткани и превышает прочность лицевогоHowever, this method is also unacceptable for testing the face layer of paired and canned sheepskin fur, since leather break will also occur without the appearance of a crack in the face layer. The magnitude of the tensile stress at which the sample breaks, characterizes the strength of the entire leather fabric and exceeds the strength of the facial skin.
СЛОЯ, завыша тем самым результаты по определению прочности лицевого сло .LAYER, thus overstating the results to determine the strength of the facial layer.
Целью.насто щего изобретени вл етс повышение точности результатов при испытании прочности лицевого сло парньх и консервированных овчин .The purpose of the present invention is to improve the accuracy of the results when testing the strength of the face layer of boys and canned sheepskins.
Поставленна цель достигаетс тем, что в способе, включающем раст жение The goal is achieved by the fact that in a method involving stretching
10 образца, измерение раст гивающего усили и оценку по нему прочности лицевого сло в момент по влени в нем трещины, волос ной покров образца перед раст гиванием раздел ют на два 10 of the sample, the measurement of tensile stress and the evaluation of the strength of the face layer on it at the moment of the appearance of a crack in it, the sample’s hair surface before stretching is divided into two
15пучка , араст жение образца осуществл ют путем приложени усилий к каждому пучку.15 bundle, the sample is strained by applying force to each bundle.
Способ заключаетс в следующем.The method is as follows.
От парных или консервированных ов20 чин со стандартного участка вырезают кусок. Из куска вырубают образцы, которые помещают в эксикатор и выдерживают до одинаковой влажности (сFrom a paired or canned ov20 rank with a standard plot cut a piece. Samples are cut out of the piece, which are placed in a desiccator and kept up to the same humidity (with
