Polyester Fibers

Currently, textile dyeing companies determine their market according to the raw materials processed, which are based on 100% cotton fibers, these fibers are directed to an exclusive market and therefore these companies establish criteria of high quality standards in each of its processes, dyeing being one of the most demanding due to its fastness parameters and color specifications, these characteristics establish the competitiveness of expanding a product portfolio with the incursion of 100% fiber-based clothing polyester and with cotton blends.Some studies suggest the implementation of the dyeing process of these fibers, allowing the organization to have new production alternatives, dyeing processes for polyester and cotton are carried out with heat treatment between 60 °C and 130 °C respectively, with the use of dispersed and chemical dyes; as in the dyeing of Polyester-Cotton that are made in bathrooms established in each stage. Color and solidity tests are performed according to quality parameters, with light and wash fastness controls. Within these dyeing conditions it is essential to determine the thermal gradients to be applied, whose variable must be controlled to optimize the dyeing of polyester fibers and mixtures.The present study evaluates the pre-treatments and the temperature gradient behavior stage in the dyeing process of polyester fibers, taking into account the dyeing curve, in which only the temperature gradient varies. Mathis-ALT-B equipment is used for the dyeing process, for thermal gradient conditions of 135 °C with gradients of 0.3-4.0 °C/min, rotation speed 40-70 RPM, and as colorants were used Novacron, Terail and Liandisperse for cotton and polyester fibers respectively. The results show that the use of dispersants and anti-breakage agents work to prevent failures and improve the corresponding colors, but a high gradient increases the migration of the dye and breaks in the fibers, but in low gradients (2 ° C/min ) The quality of diffusion and dyeing is better and, therefore, prevents reprocessing in the dyeing stage.

Yield And Quality

The formation of fiber flax yield and quality parameters depends on many soil-climatic, breedinggenetic, as well as anthropogenic factors. The quality of flax fiber is a combination of a number of features and properties that depend on the varietal characteristics of plants, the conditions of their cultivation, technologies for harvesting and straw retting, as well as on the processing modes of raw materials. During plant vegetation (90-130 days) many factors such as soil conditions (pH 4.8-5.5, humus 1.8-2.5%, P2O5 and K2O – 150-200 and 100-200 mg/kg, respectively) and the area of plant nutrition (15-30 million seeds/ha), temperature regime (the sum of active temperatures 1000-1800ºC), water supplying (400-430 units of water mass to create 1 unit of dry matter) and insolation (the arrival of FAR during the growing season 20-25 kcal / cm²), contamination of weeds (more than 60 annual and perennial species) and pests (more than 200 types of fungal, bacterial and viral diseases), features of phytosanitary measures (more than 50 chemicals) and agrotechnologic manners (Federal Register of technologies for the production of crop products) have a great influence on the quality of flax raw materials and can be a limit factor. Environmentally hazardous pollution of air, water and soil - the main components for the production of fiber flax – strongly affects the yield and quality of flax products. The development of waste-free environmentally friendly technologies for the cultivation, harvesting and processing of flax is an urgent task of scientific support of the industry. The main environmental factors affecting the yield and quality of fiber flax are discussed in the article.

Abstract The connection between diet and health was known to the oldest civilizations. Meat processing has influenced the increase of meat consumption, protein utilization and its energy value. Fermented sausages which are prepared in a safe way are rich in animal proteins and are an important part of the diet. Meat and adipose tissue are the basic ingredients in the production of fermented sausages, along with spices and salts, and other additives depending on the specifics of the product. Ripening is a process that separates raw sausages from all other types of sausages, and the quality of raw materials and their treatment directly affects the quality of the finished product, because the process of fermented sausage production is dominated by biological and biochemical processes. Different types of foods can cause food-borne illnesses, one of which is zoonotic yersiniosis caused by Yersinia enterocolitica. Due to the importance of Yersinia in meat, the European Food Safety Authority (EFSA) recommended that in addition to controlling the presence of Salmonella, it is mandatory to examine pork carcasses for the presence of Y. enterocolitica.

Abstract The basic economic goal of pig iron process is to produce a finished product at the highest possible quality and at the lowest possible cost. The quality of pig iron depends on the quality of raw materials used in the process, quality of fuels and process parameters. The cost of fuel is one of the basic component of cost of pig iron production. Therefore, consumption of fuels should be minimized while maintaining its high quality. The main technological fuel of this process is blast furnace coke. Very often, cheaper alternative kinds of fuels are used in the form of finer sorts of coke or alternative fuels (e.g. coal dust). However, they can be used only in a limited amount. The aim of the paper is the assessment of the selected quality parameters of stabilized coke used in the blast furnace process and the comparison of their values with requirements.

Relevance. Polysaccharide vaccine quality assessment must, on the one hand, comply with modern domestic and international regulatory documents, and on the other hand, reflect the characteristics of newly developed drugs. The list of drugs registered on the Russian market is constantly expanding due to the development of new effective vaccines and the introduction of new production sites. Thus, the expert requirements for assessing the quality of these drugs and the information content of the documents submitted as part of the registration dossier need to be updated.Aims. The aim is to update the expert assessment of quality in preclinical and clinical studies of polysaccharide vaccines, as well as to revise the evaluation of quality parameters depending on the composition and structure of the finished product.Conclusions. We highlight the key problematic aspects of assessing the protective properties of purified polysaccharides: in particular, the problems related to the natural immunity of animals to diseases caused by bacterial species that are relevant to humans and, as a result, the lack of an adequate experimental model. Modern trends in the characterization and subsequent confirmation of the structure authenticity of purified and conjugated polysaccharides are taken into account. An analysis of the latest international and domestic pharmacopoeial requirements for the quality of polysaccharide vaccines is carried out. The disadvantages of selected methodological approaches to the evaluation of quality parameters such as «Identification» and «Molecular mass distribution» are noted. It is shown that it is necessary to generate recommendations for the examination of polysaccharide vaccines which would unify the recommendations for completing registration dossiers and forming specification files by taking into account each individual peculiarity of this type of drugs.

The processes of processing of grain raw materials are quite common at food and processing enterprises in Ukraine. This is due to the significant volumes and wide variety of these raw materials, as well as a wide range of semi-finished products and finished products that are obtained from them. In particular, the country's enterprises process such types of grain crops as wheat, barley, rye, corn, oats, rice, sorghum, millet, chumiza, mogar, paiza, buckwheat (buckwheat family), mealy amaranth (amaranth family). Peas, beans, lentils, soybeans and other legumes are also grown in large volumes. All these raw materials come from different farms, in different conditions, in a wide range of varieties and quality, thus, even for the same type of grain raw materials such parameters as the shape and size of grains, their weight, moisture, glassiness, hardness, degree of damage and many others may differ significantly. Depending on the type of products obtained from grain raw materials (flour, cereals, malt, bran, starch, gluten, molasses, alcohol grains, vegetable oil, oilcakes, meal), the technologies for its preliminary processing may have significant differences. The purpose of this work is to develop a methodology for choosing a rational sequence for processing grain raw materials, taking into account the initial quality parameters, conditions of a specific production and criteria for the efficiency of working processes (productivity, energy intensity and quality of finished products). The article also provides options for technological schemes for the preliminary processing of the main types of dry grain raw materials. The proposed sequence for the development of these technological schemes can further serve as the basis for creating a computer program for automated synthesis and analysis of rational options for technological processes for processing dry grain raw materials.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.
