Funny bomber jacket made of functional materialDetachable hood with synthetic fur (We only use animal-friendly vegan fur. The fur trimming are detachable for easy cleaning.) The sparkling frontal 2-way zip is a real eye-catcher. Outer jacket and lining made of technical fabric. The jacket has sealable outer pockets, and it also has a sealable inner pocket for your mobile phone. On the front, there is a continuous sparkling 2-way zip with wind protection. Even when we are not doing any sports at all, our body is generating heat, and we begin to sweat. A healthy adult produces 200 to 700 ml of sweat on average on a daily basis. It goes without saying that this is higher when you engage in physical exercise or during the summer. In order to keep our body temperature at a comfortable level and to keep sweat levels on the skin as low as possible, a jacket must have good ventilating properties as well as breathability. The material of the Funny Facts bomber jacket can absorb up to 1000 g of steam within 24 hours per square metre, and it has the ability to transfer this to the outside. An ISO standard says that water-tight textiles must have a water column of at least 1,300 mm. In a lab, a tube is placed on a sample of the fabric to be examined, and after this, the tube is filled with water. This process checks which water level penetrates the fabric. This means that, if the water only penetrates the fabric at more than 1,300 mm, the material is deemed water-tight. The Funny Facts bomber jacket only lets water through from 3,000 mm.
The Conference Board of Canada defines innovation as a "process through which economic or social value is extracted from knowledge through the generation, development and implementation of ideas to produce new or improved products, processes and services." The Department of Trade and Industry, UK defines it as "the successful exploitation of new ideas". As far as India is concern, only small investment (0.9% of GDP) on R&D as compared to USA (2.7% of GDP) and China (2.08% of GDP). An illustration of the importance of new product development can be seen in the area of the TECHNICAL TEXTILES. Country's technical textiles market which is currently estimated at $14 billion is likely to reach a level of $32 billion by 2023( 20% growth per annum). However, this book is divided into four chapters. The first one deals with product development, second for design logic of textile products, third for simulation of specific properties or structures leading to design, fourth is for case studies related to product development. More than 20 case studies are are illustrated with reference in technical textiles to explore the possibilities of product development in technical textiles.
In recent years, there has been significant interest in the utilization of natural materials for nanomaterials which impact a broad range of fields including tissue engineering, smart textiles, electronics, energy, coatings and more. Natural polymers such as silk, have received renewed interest due to their unique properties and potential applications. Silk fibers are traditionally 10-20 µm in diameter. This book researches the scientific implications of reducing the diameter to the nanoscale and adding nanofillers in the form of carbon nanotubes by the electrospinning process. The effects of post processing treatments on the physico-chemical properties of the nanofibers were also studied. Statistical analysis was applied to develop processing windows that can reproduce nanofibers less than 100 nm in diameter. The extensive experimental works outlined in this book are creative and commercially justifiable solutions to technical challenges relating to the development, fabrication, characterization, and optimization of next-generation advanced nanomaterials.
The air-jet texturing process is by far the most versatile continuous yarn texturing method. Production is economical and a variety of yarns can be produced to meet the needs of apparel, household and technical textiles. To study the effect of blend proportion on the physical characteristics of dry and wet blended air-jet textured yarns, multi filament yarns (fdy) were used as feeder yarns for the production of blended textured yarns in different proportions under dry, wet and single component wet conditions.Those blended yarns were used as weft with constant warp of PV spun yarn on CIMMCO Auto loom. The yarns and fabrics manufactured were tested and analyzed for various characteristics. In wet texturising, Polyester/Nylon blended yarns exhibit good loop stability with high nylon proportion. Bulk of Polyester/Nylon blended air-jet textured yarns decreases with increase in nylon proportion in dry as well as wet texturising. In comparison to the wetting of single component, pre-wetting of all the component of the feeder yarn results in high loop frequency. Drape, crease recovery, abrasion resistance and tensile properties are better achievable with Nylon 6 rich fabrics.
Braiding is the process of interlacing three or more threads or yarns in a diagonal direction to the product axis in order to obtain thicker, wider or stronger textiles or, in the case of overbraiding, in order to cover a profile. Braids are becoming the reinforcement of choice in composite manufacturing, and have found a range of technical applications in fields including medicine, candles, transport and aerospace.

Three dimensional voluminous nonwovens are a valuable and new generation source to replace the less-recyclable and less environment friendly polyurethane foams with the fulfilment of various technical, functional, design and aesthetic requirements for automotive textiles. The book describes about various 3D voluminous nonwovens structures and is focused on vertical laid Wavemaker technology based nonwovens. In the case the manufacturing technique to produce Wavemaker nonwovens, effect of fiber fineness, structural parameters, process parameters and different type of feeding web structures on the various properties of the Wavemaker nonwovens for car seat and headliner cushioning materials are illustrated. The book also purposes the evolution of context aware application to determine what to test, how to test and the appropriate metrics to use.
The industrial sector is very promising for the use of solar thermal technology, since it accounts for a large share of the total final energy consumption (e.g. 27 % in Germany in 2010) and it predominantly uses the consumed energy as thermal energy (74 % in Germany in 2010). In order to develop this area of application, it is necessary to understand which industrial sectors have the highest potential, which processes within these sectors are most suitable for the integration of solar heat as well as to quantify the possible contribution to the industrial heat demand. For this thesis, the industrial heat consumption in Germany is analyzed, which leads to the selection of the 11 most promising sectors within industry. These are Chemicals, Food and beverages, Motor vehicles, Paper, Fabricated metal, Machinery and equipment, Rubber and plastic, Electrical equipment, Textiles, Printing and Wood. The theoretical potential of solar heat for industrial processes below 300 °C in Germany adds up to 134 TWh per year, the technical potential (considering efficiency measures, limited roof area and a solar fraction) being 16 TWh per year or 3.4 % of the overall industrial heat demand.Solar thermal systems can achieve higher system yields in industrial applications compared to domestic ones. At the same time, systems can be more complex in industrial applications. In order to design and operate solar process heat systems efficiently and to exploit the large potential, possible faults of such systems and their impact have to be evaluated. In this thesis, an implemented solar process heat system is methodically analyzed based on measurements and simulations with a validated model. Several faults are identified and their influence, as well as the influence of a reduced load on the system yield is evaluated. The analysis shows that a reduced load is most influential. Further, the most important impact factors on the system performance are identified: the collector parameters (?0, a1) and load characteristics (mass flow, temperature). The design of solar process heat systems is in many cases very demanding, hence costly. This high effort is a major barrier for a further development of solar heat for industrial applications. The decision to install solar thermal systems is in most cases based on solar heat generation cost. Collector field and heat store size are the most important figures for the estimation of the overall cost of a solar thermal system. Therefore, a simple approach for dimensioning the collector field and heat store is developed in this thesis in order to enable manufacturers and planners on one hand and costumers on the other hand to make a decision in favor or against a solar process heat system. In addition to investment cost, the specific system yield, which is determined for selected process heat applications in this thesis, is necessary to calculate solar heat generation cost. Finally, indications on the necessary accuracy of the load profile are provided to help to reduce effort in the design phase.
Colloquium on„Integrated Best Available Wastewater Management in the Textile Sector“September 19, 2018at Max-Planck-Institut für Festkörperforschung Lecture Hall 2D5, Heisenbergstraße 1, 70569 Stuttgart-BüsnauScientific Head: Dr.-Ing. Harald Schönberger University of Stuttgart Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA)Apart from cotton cultivation and the production of dyestuffs and optical brighteners, textile finishing – also called textile wet processing – is one of the environmental hotspots. The dominating emission mass stream from textile finishing is wastewater as practically all inorganic and most of the organic (more than 90 %) chemical compounds are discharged with wastewater. Emissions to air, although not negligible, and with solid wastes are of significant lower relevance. In addition, in many parts of the globe, water availability and water scarcity respectively are of increasing concern triggering the need to avoid, reduce or recycle textile wastewater.Against this background the colloquium will contribute to the development of integrated best available wastewater management practices in the textile sector. This comprises the minimisation of water, energy and chemicals consumption by process optimisation (process- and production-integrated measures) and the careful selection of chemicals products. The latter means that the chemical products should be free of substances which are non-biodegradable or which are toxic or do have a negative impact on aquatic life.As textile wastewater pollution cannot be fully prevented at source, the colloquium also focusses on its advanced and effective treatment with special consideration of its recycling in case of limited water availability or scarcity.The programme covers the aforementioned aspects. Well-known speakers will present latest technologies and technical concepts to the audience from textile finishing industries, retailers and brands, techniques providers, textile associations and authorities from national, regional and local level, GIZ and representatives of the German Partnership for Sustainable Textiles.The colloquium is being organised by the “Forschungs- und Entwicklungsinstitut für Industrie- und Siedlungswasserwirtschaft sowie Abfallwirtschaft e.V. (FEI)” in cooperation with the Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA) of the University of Stuttgart and the Partnership for Sustainable Textiles.
The technical importance of flexible composite structures needs no emphasis nor has there been any lack of material descriptive of their manufacture or properties. The starting points of such descriptions have invariably been from the viewpoint of the rubber industry and the presence of a suitable textile has been taken for granted, its strength properties indicated and the technological content confined to the manufacturing process within the rubber industry. An attempt is made here to work from the textile outwards. Industrial fabrics are far heavier than garment textiles, are not produced in the same bulk quantities and need to be specially constructed to provide the balance of properties which will combine with those of the rubber to give the final. product. The most important composite structure formed from textiles and rubber is, of course, the pneumatic tyre. It may therefore seem strange that no chapter deals with this. The reason is quite simple. To deal with the structure and design of the pneumatic tyre in a similar depth of detail as is done here for conveyor or power transmission belting, or hose, would require disproportionate space, in fact, a second volume equal in size to the present one. This book discusses from the textile viewpoint the various reinforced rubber structures used industrially with the exception of the tyre. These other uses of industrial fabrics can be discussed in adequate detail and cover the whole range of the technology involved in the space available in the one volume.
