(54) СПОСОБ ОПРЕДЕЛЕНИЯ ОЖИДАЕМОГО СОДЕРЖАНИЯ ПОРОКА КОЖИЦА С ВОЛОКНОМ В ВОЛОКНЕ ПРИ ПЕРВИЧНОЙ ПЕРЕРАБОТКЕ ХЛОПКА(54) METHOD FOR DETERMINING EXPECTED CONTENT OF LEATHER SKIN WITH FIBER IN FIBER WITH PRIMARY COTTON PROCESSING

II

Изобретение относитс к области хлопководства и хлопкоочистительной промышленности и может быть исполь - зовано дл определени по лабораторным образцам хлопка новьк средневолокнистых селекционных сортов ожидаемой величины порока кожица с волокном в волокне при его проьшшленной переработке.The invention relates to the field of cotton growing and the cotton cleaning industry and can be used to determine the expected value of blemish from the fiber with fiber in the fiber during its advanced processing by laboratory samples of cotton new medium-sized breeding varieties.

Известен способ оценки предрасположенности сем н хлопчатника к порокообразованию , при котором определ ютс размеры утолщений в халазальной части продольных срезов сем н под микроскопом и по наличию процентного содержани сем н, имеющих размеры кожуры халазальной части , превышакмцие установленные пределы , определ ют ориентировочно процентное содержание в волокне кожицы 1.There is a method for estimating the susceptibility of cotton seeds to malformation, which determines the size of the bulges in the chalazal part of the longitudinal sections of the seeds under a microscope and the percentage of seeds that have the size of the chalasal part, exceeds the established limits, determines the percentage in the fiber peel 1.

Однако известный способ позвол ет получить конкретную величину процента кожицы в волокне в процессе первичной переработки хлопка.However, the known method allows to obtain a specific value of the percentage of skin in the fiber during the primary processing of cotton.

Цель изобретени - определение ожидаемой величины порока кожица с волокном в волокне по лабораторньи образцам с точностью до 0,1-0,2%абс.The purpose of the invention is to determine the expected amount of blemish with the fiber in the fiber according to laboratory samples with an accuracy of 0.1-0.2% abs.

Эта цель достигаетс тем, что согласно способу вы вление сем н с дефектами халазальной части осуществл ют путем отрыва пр док волокон заданной массы от халазальной части сем н, а оценку ожида емога содержани по1юка производ т по количеству пр док волокон,оторвавшихс с кожицей по формулеThis goal is achieved in that according to the method, the detection of seeds with defects in the chalasal part is carried out by tearing off the fibers of a given mass from the chalasal part of seeds, and estimating the expected content of the stream is made by the number of fibers that are cut off from the skin by the formula

Claims

Preventing fibers that have come off the skin. An example. For the study, the volatile fiber cover is placed in the same plane along the longitudinal axis of the seed, then the prepared bullets are placed for at least 4 hours in a protective chamber or room where atmospheric conditions meet the requirements of GOST 10681-75 Textile materials. Climatic test conditions (relative humidity — 6512%, temperature — 20t2 ° C). Under these standard conditions, tests are carried out. The fibrous cover of the volts facing the micropolar end of the seed is fixed to the lower clamp of the DS-3M dynamometer, and filled to the upper clamp strand from the chalasal part of the seed for 2/3 of the fiber length, then a dynamometer is turned on and the upper strand is pulled off, the weight of which must correspond to 6, OtO, 3 mg, which is checked by weighing it on a torsion balance of the VT type. dke about limited by visual inspection and recorded in tab. e. and by the percentage of such prints in the total amount of grade testing (200 replications) the expected amount of blemish with fiber in the fiber is calculated by the formula 0.053 to the expected content of rock in the fiber; empirical the ratio of the percentage of the fibers of the fibers torn off the skin. Using the proposed method for determining the expected content of the blemish, the skin with the fiber during the primary processing will allow This defect in new breeding varieties for laboratory samples at an early stage of breeding varieties without carrying out industrial processing. Claims The method of determining the expected blemish content of the peel with fiber in the fiber during the primary processing of cotton consists in detecting seeds with defects in the chalasal part and estimating the expected blemish content, which is aimed at increasing the reliability of the results. n with defects of the hapazapy part is carried out by tearing off the fibers of a given mass from the halazap part of the seeds, and estimating the expected content of the defect is made by the number of fibers that come off the skin, according to the formula 0.053-b, - the expected content of the defect in the fiber; 0.053 is an empirical coefficient determined experimentally; the percentage of the fibers present is detached from the skin.
