One of the most promising areas for expanding the range and improving the quality of textile products is the application of a systematic approach to predicting their properties. The systematic approach takes into account the interconnection of operations throughout the entire chain of the textile manufacturing process, so its application is appropriate and relevant. The systematic approach is a set of methods and the appropriate sequence of their application, which provides a comprehensive view of a particular problem and directions for its solution. It is typically applied to all technological systems that are of an orderly nature. Technological processes in the textile and light industry are sequential chains of certain operations that are interconnected and allow you to get the final product in accordance with the technical specifications. Each technological operation requires compliance with the requirements for equipment and personnel qualifications, which affects the quality of the semi-finished product and the finished product as a whole. The aim of the study is to analyse the application of a systematic approach to predicting the properties of textile products, improving their quality and expanding their range. The systematic methodology consists of a set of methods and a certain sequence of their application. It provides a comprehensive view of the goal and ways to achieve it. An in-depth analysis of existing systematic approaches in some industries has been conducted. To predict the properties and quality of textile products, it is advisable to apply a systematic approach that allows to identify the elements of the system, their grouping into subsystems and the relationships between them and to guarantee their rationality. The properties of finished products are directly influenced by the properties of the derivative raw materials, the state of technological equipment and the level of qualification of production and management personnel. The following articles will highlight further research in the application of a systematic approach to predicting product properties at Ukrainian textile and light industry enterprises, which will allow us to build a mathematical model and a general algorithm for predicting product properties and managing their quality.

“…The use of special machines, which include roll crushers, is advisable only if they are loaded to the full [3]. It should be noted that in addition to sunflower and corn stubble, it is also advisable to carry out operations of grinding and processing green manure, processing of rapeseed stubble, cereals, etc.…”

This paper reports a study of the technological process of grinding plant residues of sunflower and the causal relationships of factors that form the system of quality indicators. The necessary prerequisites for determining rational modes and parameters of the roll crusher have been devised. A prototype of the roll crusher was designed and fabricated, in which the cutting knives are arranged along the entire width of the grip in a staggered manner, with the possibility to change the angle of inclination to the axis of drum rotation in the range of 5...20°. It was established that in the case of the right-side arrangement of the cutting edge of knives, the highest total level of the percentage of crushed stems in the range of 101‒150 mm with an additional load weighing 800 kg exceeded by 1.58 times the corresponding indicators of the roll with an additional load of 600 kg. The largest overall value of the percentage of crushed stems in the range of 0‒200 mm when additionally loading the roll with 800 kg was 1.13 times higher than the corresponding indicators of the roll with an additional load of 600 kg. In the range of 0‒200 mm, with an additional load on the roll of 600 kg, at the left-side arrangement of the cutting edge of the knives of the roll, higher total percentage of crushed stems was observed compared to the right-side arrangement. At a speed of 7.45 km/h, 13.6 km/h, the cumulative value of the percentage of crushed stems exceeded the corresponding indicators at the right-side arrangement of knives by 1.09 times, at the speed of 18.6 km/h – by 1.04 times, at the speed of 22 km/h – by 1.04 times, respectively. It has been noted that at the left-side arrangement of the cutting edge of the knives of the roll, the percentage of crushed stems in the range of 51‒100 mm, with an additional load of 600 kg, exceeded the corresponding indicators with an additional load of 800 kg. At the speed of 10.08 km/h, it was exceeded by 1.9 times; at the speed of 13.6 km/h – by 1.44 times; at the speed of 18.6 km/h – by 1.96 times; at the speed of 22 km/h – by 1.99 times, respectively

“…В роботі [6] встановлено математичну залежність, яка на етапах проектування дозволяє використати моделювання для аналізу структури машин для обробітку рослинних матеріалів (стерні кукурудзи, ріпаку, сидеральних залишків). Подрібнення і зароблення рослинних решток запропоновано проводити контролюючі такі показники: кількість непошкоджених частин стебел кукурудзи довжиною понад 5 см та глибина зароблення подрібнених стебел понад 10 см.…”

В статті досліджено вплив на подрібнення пожнивних решток кукурудзи дисковими знаряддями таких параметрів, як: швидкість руху агрегату, встановлена глибина обробітку ґрунту, спосіб руху агрегату. Аналіз даних польового досліду дав можливість визначити оптимальні параметри швидкості руху ґрунтообробного агрегату, глибини обробітку та спо-собу руху по полю, при яких забезпечується найменший середній розмір подрібнених рослинних решток. Для всіх глибин обробітку (7см, 10см, 14см) та напрямків руху відносно рядка найменша середня довжина решток була зафіксована при швидкості руху агрегату в діапазоні 14 – 16км/год, а найбільша – в діапазоні 8 – 10км/год. При порівнянні напрямків руху відносно рядка в більшості випадків кращі результати отримані при руху під кутом 35°до рядка.
