Статья научная
Technology, currently at the peak of its development, provides an opportunity to increase the level of education of modern man. As a consequence, the development of new clothing models using neural networks is also becoming a more efficient way to optimize design processes. By applying neural networks, results can be achieved quickly and easily. Artificial intelligence empowers and optimizes work in the fashion industry: it recognizes clothes from photos, accesses virtual fitting sessions, and, without much effort, easily selects the perfect size. The program will automatically design the pattern and technically reproduce patterns by size, height and fullness. Artificial intelligence will require less creative work from the author, and the designers themselves will be able to spend more time on their creativity. The research paper utilizes Microsoft Bing to facilitate the creation of new designs for clothing patterns. It is an artificial intelligence that can be used to create images, solve problems and get new ideas. With the help of this program it is planned to create an experimental series of Kyrgyz national costumes, the details of which will be designed in the graphic program of Grafic 12 clothing designer.

Study on the strength of needle-punched nonwoven material made on the basis of sole trader "Miras"
Статья научная
Coarse sheep wool and wastes from the production of woolen yarns are currently considered to be a special waste that requires large disposal costs due to low market demand. For this reason, wool has serious consequences for the environment. However, this type of raw material is considered a promising insulating natural fiber due to its thermal and acoustic properties. Moreover, wool meets the requirements of environmentally friendly materials that are used for yurts, insulation of buildings, and acoustic insulation for the automotive industry. Nevertheless, the sustainability and energy efficiency of insulation materials are currently evaluated comprehensively. In this context, the correctness of the composition of nonwoven fabric, its thickness and strength characteristics, as well as the number of layers play an important role. The purpose of this work is to study the relationship between strength characteristics and thickness, as well as the number of layers in nonwovens made of 100 % wool mixed with coarse and fine fibers, and to determine the most optimal variant of insulating nonwovens. 4 samples of one, two, three and four-layered materials were used in the study. The tested samples of insulating materials were evaluated according to the parameters of breaking load, strength and elongation. The results of the research showed that with an increase in the number of layers of material, there is an increase in the tested two indicators: breaking load and strength. The elongation rates were uneven. Consequently, by examining all three parameters, it was found that the best option is a three-layered nonwoven material.

Milk and dairy products are often dried to reduce weight, to facilitate transportation, to extend shelf life. For example, dry fermented milk products occupy a special place in the dairy industry. Currently, their assortment is significantly expanding and the approach to food products of this group is qualitatively changing. The article presents the results of drying fermented milk protein products in two ways: using thermal and microwave drying. It was found that the duration of moisture loss in the product during heat drying increased with a decrease in temperature. With an increase in temperature from 400C to 500C, there was a decrease of about 25% in the moisture content of the test samples during 5 hours of drying in the dehydrator. Drying with using of microwaves, the drying time decreased with increasing microwave power. The 900 W power reduced the drying time by 2 times compared to the 270 W power to obtain a 15% humidity result and a water activity indicator in the range from 0.382 to 0.394 units.

Currently there is an acute shortage of fibres and proteins in the human diet, resulting in various diseases. The modern market needs a product capable of diversifying the range in the sector of functional, dietary flour confectionery. To this end, the article shows one of the ways to improve the macronutrient composition of waffles, especially with regard to the protein-carbohydrate component of the product. Laboratory analysis showed that the introduction of pea protein, chicory root syrup and apple fiber into the composition of flour and confectionery increased protein content by 3.3% in wafers made of rice flour only and by 5.6% in waffles made of a mixture of whole grains and rice flour. The amount of sucrose decreased in «Rice» waffles by 2.6% and by 2.3% in «Wheat-rice» waffles, and the amount of fiber on average is 3-4 times more, compared to the control sample. In comparison with the control sample, increased the average number of essential amino acids such as: lysine - in 1.5 times; phenylalanine - in 1.25 times; leucine and isoleucine - in 0.8 times; methionine - in 1.5 times, threonine - in 3 times. Thus, the study resulted in the development of dietary plant based soft waffles with improved macronutrient composition, able to expand the range of functional products and can be recommended for dietary nutrition.
