Non-woven Textile Materials from Waste Fibers for Cleanup of Waters Polluted with Petroleum and Oil Products

Medical textile is an extremely important subcategory of technical textile because it is covering a wide range of products. The term medical textile itself covers all types of textile materials that are used in the healthcare system for various purposes. Medical textile is also known as health textile and is one of the fastest growing sectors in the technical textile market. The growth rate of technical textiles in this area is due to constant improvements and innovations in both areas: textile technologies and medical procedures. Textile structures used in this field include yarns, woven, knitted and non-woven textile materials as well as composite materials reinforced with textiles. The number of applications is large and diverse, from simple surgical sutures to complex composite structures for bone and tissue replacement, hygiene materials, protective products used in operating rooms and in the process of postoperative wound treatment. The purpose of this paper is to emphasize the importance of technical textiles for medical, surgical and healtcare applications, to indicate which textiles are currently used in this field.

Tomography Data

The internal structure and mechanics of the fibre materials, such as yarn or woven textile, are highly complex. Exploring the fibre structure is an essential step in material engineering either from the experimental or computational point of view. In this study, a new method to extract geometrical and morphological parameters of fibre structures is proposed. The method benefits from standard image analysis and machine learning technique to efficiently extract fibre segments from microcomputer tomography data. The proposed algorithm is tested on the yarn and woven textile materials with different resolution and quality. The developed method can extract the individual fibres with varying accuracy from 73-100% with processing time 2-5s on the tested samples.

Picture Frame

Our research aims to develop a shear forming envelope for the preforming of textiles, a critical step in the manufacture of fibre-reinforced composite materials. This paper demonstrates the progress towards this aim by conducting picture frame tests to empirically determine the locking angle of non-crimp fabrics with different fibre orientations. While conventional shear tests typically utilise woven textile samples with orthogonal fibre directions of 0°/90°, the investigation of non-crimp fabrics, especially with non-standard fibre orientations, is less common. As a result, there is little knowledge about the shear deformation behaviour of these fabric types, despite their relevance to the aerospace industry. In this study, the shear locking angles of various carbon fibre non-crimp fabrics are investigated, gradually reducing the relative fibre angles of the textile materials from ±45° to ±22.5°. Previously, it was observed that unidirectional 0° reinforcement layers induce draping defects when forming multiaxial non-crimp fabric stacks into curved aerospace stiffeners. Their substitution by reinforcements with smaller cross-ply angles such as ±30° resulted in better formability and reduced defects. It is however unclear, how the shear locking angle decreases with more acute cross-ply angles. Here, we report for the first time a correlation between the fibre orientation of the non-crimp fabric and its shear locking angle. The resulting shear forming envelope provides composite design and manufacturing guidance for an enhanced utilisation of the advantageous but anisotropic properties of carbon fibre textiles.

The Cost

The paper analyzes the consequences of the abolition of the export duty on oil and oil products as a necessary step to stimulate energy efficiency of Russia’s economy and eliminate underdevelopment provoked by a long-term subsidizing of inefficient oil refining sector in Russia. The calculation results have shown that even taking into account several deviations from the planned scenarios of changing the parameters of tax regulation of the oil industry in 2014— 2019, the tax maneuver brought over 3.5 trillion rubles (in 2019 — 148 billion rubles) to the state budget in 2014—2017, mainly due to an increase in the base mineral extraction tax rate, and contributed to an increase in the depth of oil refining from 72% to 85%. In addition, the article analyzes possible risks associated with the current plan for reforming the taxation of the industry until 2024 and proposes an alternative that could level some of them. A comparative analysis of the effects of the tax maneuver under the current reform plan and the alternative variant suggests that the latter will allow to achieve a greater total budgetary effect in four years, reduce the cost of subsidizing domestic oil refining, increase the efficiency of Russian vertically integrated oil companies, and reduce the growth rate of oil products prices in the retail market.

The problem of losses of oil products from leaks during their storage and transportation at oil supply facilities is considered. The influence of oil product leaks on the environmental situation around oil depots and gas stations is shown. A detailed overview of existing methods and tools for detecting leaks of petroleum products from storage facilities is presented. The evaluation of their effectiveness. Two methods for detecting oil leaks and devices based on them are proposed. The first device monitors the movement of liquid in the tank, the second-detects petroleum products in wastewater. The problem of recovery of petroleum vapors and environmental pollution from the release of vapors of light fractions into the atmosphere is also considered. An overview of existing methods and means of recovery of petroleum vapors is presented. Two methods and devices for capturing oil vapors and returning them to the reservoir are proposed, based on different principles: vapor absorption in the cooled oil product and vapor recovery on the principle of the Carnot cycle. It is shown that these devices can provide effective detection of oil leaks and recovery of their vapors, as well as improve the effectiveness of environmental protection at modern gas stations and tank farms.
