SammanfattningUppsatsen är utformad efter ett förslag från Anders Ryberg vid Länsstyrelsen i Västra Götalands län. Förslaget var att lokalisera användningsområden för den ull som i dagsläget kasseras i Sverige. I början beskriver vi grundläggande fakta om ullfibern för att ge dig som läsare ett bättre begrepp om ullfiberns användningsområden som senare tas upp i arbetet. Detta följs av en beskrivning av de miljöaspekter som ullanvändningen medför, vilket dessutom är viktigt ur en marknadsföringssynpunkt. De ullkvalitéer vi har i Sverige beskrivs därefter kortfattat, följt av en presentation av svenska företag och projekt som arbetar med svensk ull. Därefter beskrivs Australiens, Storbritanniens och Norges ullindustrier. Deras marknadsfringsstrategier och infrastrukturer för ullhantering är viktiga att ta del av om den svenska ullindustrin ska kunna konkurrera i framtiden. Vi har även funnit många intressanta användningsområden för den svenska ullen. Däribland finner vi geotextil, isolering och ull i avfallshantering enklast att producera utifrån de förutsättningar vi har i Sverige. Våra slutsatser är att det krävs en hel del initiativ, framförallt från fårägarna i Sverige, för att skapa en större efterfrågan på svensk ull. Tillvägagångssättet är att skapa infrastruktur för uppsamling och sortering av ullen runtom i landet, sedan marknadsföra ullen med hjälp av information om dess unika egenskaper och positiva miljöaspekter. / <p>AbstractThe thesis is developed from a proposition by Anders Ryberg at the county administration board of Västra Götaland. The proposition was to evaluate new fields of utility for the Swedish wool which today is disregarded. First off we give a basic description of the facts concerning the wool fiber in order for you as a reader to better comprehend how the wool fiber applies in different fields of utility, which is brought up later in the thesis. This is followed by a description of the environmental aspects which comes with the usage of wool, which also is important from a marketing point of view. The different types of wool we have in Sweden are then briefly described, followed by a presentation of Swedish companies and projects who are working with Swedish wool. Thereafter we describe the wool industries of Australia, Great Britain and Norway. Their marketing strategies and infrastructures for wool handling are important to acknowledge if the Swedish wool industry are to be able to compete in the future. We have also found many interesting fields of utility for the Swedish wool. Among many we have found geotextile, isolation and wool in waste management the easiest ones to produce looking at the prerequisites we have in Sweden. Our conclusions are that a lot of initiative will be needed, especially from the Swedish sheep owners, to be able to create a larger demand for Swedish wool. The way to go about it is by creating an infrastructure for collecting and sorting of the wool around the country, then implicate marketing with information about the unique abilities of wool and its positive environmental aspects.</p><p>Program: Textil produktutveckling med entreprenörs- och affärsinriktning</p>

This is a textile design project aim to make acommunication stage with smart colors (Thermo-­‐chromic leuco-­‐dyes and photo-­‐luminescent colors). Allthrough a research question has been designed. Theobjects, colors, and materials have been chosen basedon the inspirations from the stimuli. Afterwardexperimental method has been employed to reflect thetheory of the project, which was the notion of death andlife. Subsequently the design process has been startedby conception of combining textile and informationtechnology in order to make a design prototype sopeople can interact with the prototype and reactionscould be observed and sensed by human. Thiscommunication stage has its own specifications andcharacteristics that people can have their ownunderstanding of it while using it. / Program: Master Programme in Fashion and Textile Design

In recent years, due to the combination of technological advances in the fields ofmeasurement instrumentation, communications, home-health care and textile-technology thedevelopment of medical devices has shifted towards applications of personal healthcare.There are well known the available solutions for heart rate monitoring successfully providedby Polar and Numetrex. Furthermore new monitoring applications are also investigated. Amongthese non-invasive monitoring applications, it is possible to find several ones enable bymeasurements of Electrical Bioimpedance.Analog Devices has developed the AD5933 Impedance Network Analyzer which facilitatesto a large extent the design and implementation of Electrical Bioimpedance Spectrometers in amuch reduced space. Such small size allows the development of a fully wearable bioimpedancemeasurement.With the development of a Electrical Bioimpedance-enable wearable medical device in focusfor personal healthcare monitoring, in this project, the issue of power management has beentargeted and a battery-driven Electrical Bioimpedance Spectrometer based in the AD5933 hasbeen implemented. The resulting system has the possibility to operate with a Li-Po battery with apower autonomy over 17 hours.

It is the possibilities to create dynamic textile patterns in Smart Textiles that isin focus in this report. The result will be presented in form of different materialand pattern samples. The samples show both different technical solutions andinteractions needed to develop a dynamic textile pattern.My intention with this work is to enlarge the use of a decoration, as somethingmore than a static extra value. We do have a need for beautiful things in oursurrounding and I want to explore how dynamic patterns could give decorationan extended use. Where new kinds of values can be included, interaction and theinformation. The result can be applied in further research concerning bothwearables, fashion, soft furnishing as well as for public environment forcommunications. / <p>Program: Designteknikerutbildningen</p><p>Uppsatsnivå: D</p>

Textile is a global product used by all people in the world. These textiles after the use are thrown into the trash for incineration or land filling. However an efficient way that can be used to produce more energy, in an environmentally friendly process is anaerobic digestion. Waste textiles which contain cellulosic fibers (e.g. Cotton and viscose) can be converted to biogas. In this study, the performance of a two-stage anaerobic digestion process for biogas production from four different materials, including untreated jeans, treated jeans, cotton, and starch was studied. Starch was used as an easy-to-digest material to compare its digestion with that of cellulosic materials.The two-stage processes were composed of a CSTR (for hydrolysis) and a UASB (for methanogenisis) which were investigated in two different configurations, namely (closed and open systems). In the closed system, the outlet of UASB was completely returned back to the CSTR, while in the open system the UASB outlet was sent to sewage. In a stepwise progress, the OLR was aimed to increase from 2 to 20 g Vs per L per day along with reduction in hydraulic retention time from 10 days to 1 day.The results showed that the closed system was more stable when compared to the open system. The pre-treatment of jeans by NMMO helped to produce methane as that of cotton. The hydraulic retention time was decreased to less than 9 days for treated jeans and less than 5 days for starch. The overall methane yield at OLR of 4 gVS per L per day for starch and treated jeans was 98.5% and 97.4% in the closed system, whereas in the open system the yield was 77.0% and 35.5%, respectively.Another experiment was conducted to compare the performance of two-stage process with that of a single stage process of anaerobic digestion of textiles containing polyester and cotton or viscose. Viscose textiles produced more gas compared to the cotton textile; it may be due to the higher crystalline of cotton which makes it hard to be degraded by the microorganisms. Furthermore, two-stage process could able to produce more methane than the single stage process.The parameters like total solids, volatile solids, pH, gas production, gas composition, concentration of nutrients, and COD were also analyzed for both of the experiments.

New textile materials are constantly being brought into the automotive field, and automobile design is a leader in innovative and spectacular developments where smart textile materials are used. The main elements of the current project are textile material research, automotive research, design and development of two upholstery concepts for automotives using smart textiles. The added values are RFI/EMI (Radio Frequency Interference / Electro Magnetic Interference) shielding qualities, light emitting, light reflective and antistatic qualities. Values in the smart-textile area are obtained through choice of material and textile techniques. Transportation textiles are considered high performance technical fabrics, but they must also meet the aesthetic demands of the market. In the current project the design is inspired by Japanese architectural thinking and strives to relate to outdoor environment to reduce the border between indoor and outdoor environment. The inspiration source is water surfaces. The colour setting is also inspired by water surfaces. Material selection is based on the chosen added values, material qualities, appearance and availability. The result of the work is two different upholstery concepts visualizing qualities of smart materials and requests the automotive field. Sprinkle is an upholstery with light emitting, light reflective and antistatic values. The materials used are monofilament, polyester and electroluminescent wires. Wave is an upholstery design with antistatic, light reflective and RFI/Emi shielding qualities. The materials used are stainless steel yarn, rubco and monofilament. / <p>Program: Konstnärligt masterprogram i mode- och textildesign</p><p>Uppsatsnivå: D</p>

Thermal textiles used in Personal Protective Equipment (PPE) are used to protect individuals from the hazards of thermal energy. An analytical model of the diffusion of thermal energy within the fabric was developed to simulate the transfer of thermal energy due to a hot liquid splash. Based on the model results, it was determined that that the use of an orthotropic material in which the thermal conductivities in the radial and axial directions are different can be used to decrease the amount of heat transferred through the fabric and thereby increase amount of protection in PPE. An orthotropic material particularly performs well under situations where splashes are small in size and short in time duration. The increased level of protection may be enough to prevent a second-degree burn as determined by the Stoll criterion for materials in which the radial thermal conductivity is much larger than the axial thermal conductivity. , However, situations with larger splashes over longer duration, the benefits are minimal and at best may reduce the amount of energy transferred over part of the splash site thereby minimizing potential size of burn areas. A semi empirical test method in which analytical results are matched to experimental results by iteratively changing the radial thermal conductivity was presented as a way to extract information about the extent that a fabric is orthotropic. Preliminary results as compared to numerical CFD experimentation show that with a calibrated model, the method has potential of giving good results. Further physical experimentation is recommended to further validate that this method could be of use in determining the extent that a fabric is orthotropic.
