This study aims to compare different conditions in the three-step (cultivation, washing, and bleaching) production of white bacterial cellulose (BC) fabric to introduce it as a new type of fabric in the textile industry. The BC fabric was evaluated on the basis of its surface morphology and chemical structure. The “production BC” after the cultivation step was cultured using glucose as the carbon source in the Hestrin–Schramm (HS) medium. It was produced with the highest production yield (33.2 ± 6.85%), the highest thickness (0.35 ± 0.09 mm), and the flattest surface (211 nm). The bacteria remaining on “washed BC” after the washing step were washed out using 3% NaOH solution, and the nanoscale network structure maintained its integrity after washing. The white BC fabric after the bleaching step was bleached using 5% H2O2 solution. The white BC fabric with the highest white index (73.15 ± 1.09%) without a natural yellowish-brown color was produced. In the Fourier transform infrared spectroscopy (FTIR) spectra of the white BC fabric, the peaks of proteins and amino acids derived from the bacteria disappeared, while the cellulose I crystal structure was maintained. Also, X-ray diffraction analysis showed that the crystallinity of the white BC fabric increased compared to that of the control sample, and the highest crystallinity of 80.6% was obtained.

The growing increase in world energy consumption favors the search for renewable energy sources. One of the existing options for the growth and sustainable development of such types of sources is through the use of biomass as an input. The employment of biomass as solid fuel is widely studied and is no longer a novelty nor presents any difficulty from the technical point of view. It presents, however, logistic obstacles, thus not allowing their direct dissemination in every organization that is willing to replace it as an energy source. Use of biomass can be rewarding due to the fact that it can bring significant economic gains attained due to the steadiness of the biomass price in Portugal. However, the price may rise as predicted in the coming years, although it will be a gradual rising. The main goal of this study was to analyze whether biomass in the case of the Portuguese textile industry can be a viable alternative that separates the possibility of sustainable growth from the lack of competitiveness due to high energy costs. The study showed that biomass can be a reliable, sustainable and permanent energy alternative to more traditional energy sources such as propane gas, naphtha and natural gas for the textile industry. At the same time, it can bring savings of 35% in energy costs related to steam generation. Also, with new technology systems related to the Internet of Things, a better on-time aware of needs, energy production and logistic chain information will be possible.

Fabric Production

Electronic or conductive textiles have attracted particular attention because of their potential applications in the fields of energy storage, supercapacitors, solar cells, health care devices, etc. Contrary to solid materials, the properties of textile materials such as stretchability, foldability, washability, etc. make the textiles ideal support materials for electronic devices. Therefore, in recent years, various conductive materials and production methods have been researched extensively to make the textiles conductive. In the present study, an alternative method based on imparting the conductivity to the fiber-based structure for the production of conductive textiles was established. Considering the contribution of unique characteristics of the fiber-based structure to the clothing systems, imparting the conductivity to the fibrous structure before yarn and fabric production may help to protect the breathable, lightweight, softness, deformable and washable of textile structure, and hence to improve the wearability properties of the electronic textiles. In the study, carbon black nanoparticles were selected as a conductive material due to low cost and easy procurable while cotton fiber together with other fiber types such as polyester, acrylic and viscose rayon fibers were used due to their common usage in the textile industry. In addition, various production parameters (CB concentration, feeding rate, etc.) were analyzed and the results indicated that the developed alternative method is capable to produce conductive yarns and electrical resistance of the yarns was about 94–4481 kΩ. The yarns had comparable yarn tenacity and breaking elongation properties, and still carried conductive character even after washing. In literature, there has been no effort to get conductivity in this manner and the method can be considered to be a new application for added-on or built-in future wearable electronics. Also, in the study, produced conductive yarns were used as a collector to gather the nanofibers onto the yarn to produce hybrid yarns enabling the production of functional textile products.

Purpose – The cotton industry has seen many technological advances throughout history that have greatly decreased the number of labor hours required to produce a bale of cotton. The latest advancement is a harvesting system that replaces the harvester, boll buggy, and module builder with a single machine. This is an asset replacement decision where there are multiple assets being replaced but the old technology (the defender assets) may all have different remaining lives and optimal lifespans. The purpose of this paper is to find the optimal time to replace the multiple defender assets with a single challenger asset (the improved technology). The goal is to determine if the ages of the boll buggy and the module builder affect the replacement age of the conventional picker. Design/methodology/approach – The paper extends the Perrin model to allow for multiple defender assets. Findings – The paper finds that the supporting assets do sometimes affect the decision to replace a conventional cotton picker. If the supporting assets are newer, then the replacement decision may be delayed and if the supporting assets are older then the replacement decision may be accelerated. Field efficiency can affect the decision as well. Originality/value – While the Perrin model has been used extensively, the authors believe the application to a multiple asset defender is unique. Although this type of replacement decision is not common, there could be other applications as new technology is introduced on the farm.

ABSTRACTAggregate estimates of British growth during the classical Industrial Revolution have been reassessed in the past decade and present a significantly revision of earlier views of British growth. Growth was slower dian previously believed and industrial change more localized and with a smaller impact Agricultural improvement and die relative ease with which labour moved to urban industry seems central to the experience. Although industry's impact now seems less than previously believed, industrial cities transformed society because die cotton textile industry expanded to exploit the advantage of its new technology and labour moved to the cities. But while exports expanded the share of industry and caused urbanization, they did not raise per capita income much because competition ensured that the benefits went to consumers. Finally, die specific features of die British industrial revolution seem to provide only weak guide to die growth process elsewhere.

In Textile industry, production is mostly key concern for Industry owner. This always has attracted researchers and machines manufacturers to make new developments in process and machines. Air-jet is one of the leading and successful highest productive weaving machines. However, it is now well established that due to add of charges of compressed air, manufacturing cost of air-jet weaving machine is higher as compared with rapier and projectile weaving machines. This is why countries having energy issues do not prefer air-jet weaving machines comparing projectile weaving machines. In this regard, several researchers and machine manufacturers have continuously been working to improve the efficiency of air-jet weft insertion. However, industry practice is as important as design made by researchers. The aim of this research is to investigate the air consumption of air-jet weaving on industrial scale practice. In this study, five weaving machine of same manufacturer and model were selected. It was observed that despite of manufacturing same quality of fabric, air consumption was varying almost in all weaving machines. Conventionally, mill workers adopt hit and trial practice in weaving industry including airpressure setting which leads to variation of nozzle pressure. Main reason of disparity of air consumption in air-jet weaving machines may be variation of distance from compressor to weaving machines, number of joints, un-necessary valve opening and pipes leakages cause an increase of compressed air consumption.

Рассмотрены вопросы изготовления открытых и полуоткрытых полостей в труднообрабатываемых деталях путем использования твердого электролита, наносимого на заготовку перед установкой удаляемой вставки. Показаны особенности протекания процесса анодного растворения припуска при статическом состоянии рабочей среды. Такие исследования выполнены впервые. Разработаны и проверены на практике изготовления типовых деталей режимы обработки для реализации процесса. Показано, что твердые электролиты имеют перспективы для дальнейшего использования при проектировании технологических процессов изготовления сложнопрофильных изделий из металлических труднообрабатываемых материалов, в том числе внедряемых на создаваемых образцах ракетно-космической техники. Они расширяют технологические возможности комбинированных методов, в которых одним из воздействующих факторов является электрическое и электромагнитное поле с высокой концентрацией мощности в импульсе. Впервые достигнута возможность разделять сборочные единицы путем образования зазора между сопрягаемыми деталями без доступа в зону обработки жидкой рабочей среды, определяющей возможность локального съема припуска в месте сопряжения и удаления слоя материала, достаточного для разборки узлов. Заложены основы использования для нанесения твердого электролита аддитивных технологий путем наращивания равномерных слоев перед сборкой изделия. Предлагаемая технология перспективна для изготовления сборных конструкций с ограниченным доступом инструмента в зону выполнения операции. Кроме того, новая технология может успешно применяться в процессе ремонта машин We considered the issues of manufacturing open and semi-open cavities in difficult-to-machine parts by using solid electrolyte applied to the workpiece before installing the removable insert. We show the features of the process of anodic dissolution of the allowance at a static state of the working medium. Such studies have been performed for the first time. We developed and tested in practice the processing modes for the implementation of the process for the manufacture of standard parts. We show that solid electrolytes have prospects for further use in the design of technological processes for the manufacture of complex-profile products from metal hard-to-machine materials, including those introduced on the created samples of rocket and space technology. They expand the technological capabilities of combined methods, in which one of the influencing factors is an electric and electromagnetic field with a high concentration of power in a pulse. For the first time, the ability to separate assembly units by forming a gap between mating parts without access to the processing zone of a liquid working medium has been achieved, which determines the possibility of local removal of the allowance at the mating point and removal of a layer of material sufficient for disassembling the units. We laid the foundations for the use of additive technologies for applying solid electrolyte by building up uniform layers before assembling the product. The proposed technology is promising for the manufacture of prefabricated structures with limited tool access to the operation area. In addition, the new technology can be successfully applied in the process of car repair

Surat is one of the prime cities for the manufacturing of textile products in the country, having 40% of the man-made fabric production in the country. The city produces 30 million meters of raw fabric and 25 million meters of processed fabric daily. Textile industry in the city has witnessed tremendous growth in the last decade, which has led to much transportation related changes in the city. The textile industry of Surat has different segments such as weaving unit, processing unit, value addition and trading hub for carrying out various processes. The segments are located as clusters or pockets in different parts of the city or urban area. Due to the dis-integrated nature of the industry here, it produces a lot of internal goods movement. The present study is focused on analyzing the characteristics of textile fright trip generated in the city due to the initial unit of textile industry i.e. weaving unit. Stated preference survey was conducted for 122 weaving units located in different parts of the city. Multi-linear Regression model for trip generation and quantity of cloth produced is developed for estimation of textile freight trips and quantum of production. This study will definitely help the planner to identify the strategic location of the textile industry and allied supporting industry. This study further helps in understanding the trip generation and attraction in the city which affects on routine traffic as well.
