Shifty Weaves : Woven pleats which change upon viewing angle

Jungkvist, Sophie January 2020 (has links)
This work places itself in the field of woven textile design and the lenticular effect in a spatial context. The lenticular effect refers to a ribbed surface structure which changes appearance depending on from which angle it is viewed. The aim is to combine woven pleats with colours and patterns to create a lenticular effect. Bindings, patterns and colours have been investigated in both handweaving and jacquard weaving. Three suggestions for a woven, pleated, shifting textile have been developed. The three tracks are a colour shift and gradient with a surface structure, a pattern shift taking place across all sides of a pleat and a jacquard pattern hidden between the pleats. By creating a textile which shifts as it is viewed from different angles and distances, the motive is to encourage movement around the woven piece, broaden the possible uses of woven textiles and invite the viewer to take a closer look at the woven structure.

BODY - FORM - WEAVE : Investigating objects as alternative weaving looms to challenge traditional form of weave with focus on up-cycling.

Wallgren, Märta January 2021 (has links)
This work positions itself in the intersection between art, fashion and crafts. The work aims to challenge traditional ways of making clothes by investigating the relationship between material, form and body through a three dimensional hand weaving technique with focus on up-cycling. The design examples were conducted through a series of experiments where different objects were investigated as alternative weaving looms. The study resulted in five design examples that argue the importance to maintain and develop craft techniques and to give suggestions of how to address the environmental problems within the industry.

The Weave

Seipel, Alice, Carlsson, Hilda January 2022 (has links)
This project starts starts out in wanting to somehow investigate the public space. Beginning in the questions of: What kind of interventions can we achieve in the public space? What is allowed, what is encouraged - what is not? How easy or how difficult is it to achieve building something within the folds of the public space of our city?  On the scale of the intervention itself, we were interested in what things could be investigated through design and materiality: How can we, through this design, encapsulate and measure softer, hard-to-grasp elements such as time, changes and interactions? How can we design a structure that will be responsive to the traces and manifestations of these things? What materials and organization of these can embody them?

Naturen-Minnen från en kvällsvandring / Nature

Ekström, Matilda January 2012 (has links)
Naturen är ett undersökande arbete i att uttrycka och materialisera en stämning baserat på minnen från en kvällsvandring. Jag gestaltar upplevelsen och materialiserar den i textil. Genom att undersöka möten mellan olika textila tekniker vill jag skapa en kollektion som ger en förnimmelse av min naturupplevelse. Text ur Caroline Ringskog Ferrada-Nolis bok Naturen har varit utgångspunkt vid uppbyggnaden av kollektionen. Resultatet är en dynamisk textilkollektion för hemmiljö som innehåller digitaltryck, ausbrenner jacquardväv och en stickad struktur.Nature is an exploratory work on expressing and materializing a mood based on the memories of a night walk. I portray the experience and materialize it into fabric. By examining the interaction between different textile techniques, I create a collection that gives a perception of my experience of nature. Text from Caroline Ringskog Ferrada-Nolis book Naturen has been the starting point in building up the collection. The result is a dynamic collection of textiles which includes digital printing, ausbrenner, jacquard weaving and a knitted structure. / Program: Textildesignutbildningen

Isolerande och skyddande dubbelväv : Produktutveckling av ett kylande fodral / Insulating and protective double weave : Product development of a cooling case

Nyquist, Evelina, Bövik, Therese, Dao, Stephanie January 2012 (has links)
Denna rapport beskriver en produktutvecklingsprocess som behandlar utvecklandet av ett textilt material som isolerar och skyddar. Det textila materialet ska fungera till ett kylande fodral utan att förstöra dess funktion och behöver därför uppfylla en speciell kravspecifikation. Materialet ska isolera mot kroppsvärme, vara stabilt, skyddande och slitstarkt. Dubbelväv valdes tidigt i arbetet då det är ett enkelt sätt att kunna påverka det textila materialets egenskaper i form av material- och konstruktionsval, i en betydligt större utsträckning än i en enkelsidig väv. För att utveckla ett material med de efterfrågade egenskaperna har tester utförs och den metod som har använts är hypotesprövning. Med hjälp av fakta om fibrer och bindningar har kvalificerade antaganden gjorts som sedan testats för att se om dessa var korrekta. Resultatet av undersökningarna visar att fibern i materialet inte påverkar isoleringsförmågan något nämnvärt vilket var det som första antagandet påstod. Fibervalet i det material som togs fram var alltså inte den centrala frågan utan det var istället vilken konstruktion som fungerade bäst i syfte att isolera mot kroppsvärme. Ekonomiavsnittet i rapporten grundar sig i litteratursökning. En målkostnadskalkyl har lagt grunden till prissättning av produkten för att i slutändan ta reda på ett ungefärligt pris som det textila materialet i produkten får kosta. Detta för att se om materialet är ekonomiskt rimligt att i slutändan sätta i produktion. This report describes a product development process that addresses the development of a textile material that insulates and protects. The textile material is supposed work in a cooling case without destroying its function and therefore needs to meet a particular specification. The material should insulate against body heat, be stable, protective and durable. Double weave was chosen early in this report, it is a simple way to influence the textile properties of the material. This in a significantly greater extent than in a single-sided fabric. In order to develop a material with the required properties, tests have been performed and the methodology that was used is hypothesis testing. With the aid of facts about fiber and bonds, qualifying assumptions were made which then was tested to see if these were correct. The results of the surveys shows that the fiber of the material does not affect the insulation which was what the first hypothesis stated. The fiber choice of the material that was produced was not the central issue, instead it was the design that worked best in order to isolate against body heat. The economic part of the report is based on literature search. A target cost laid the foundation for the pricing of the product in order to ultimately determine an approximate price of what the textile material in the product will cost. This was made to see if the material is economically reasonable to ultimately bring into production. / Program: Textil produktutveckling med entreprenörs- och affärsinriktning

Textil och glas : ett universum / Textiles and glass : a universe

Edling, Susanna January 2007 (has links)
This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques. Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape. The paper describes the working process with choices and analyses. It describes the experiments and the making of the sculptures. / <p>Uppsatsnivå: C</p>

Energiabsorberande material : en studie av 3D-väv, non woven och D3O för förebyggande av höftfrakturer hos äldre vid fallolyckor

Saleem, Hayvee, Wictorson, Johanna January 2018 (has links)
Höftfrakturer är ett stort problem för äldre i dagens samhälle och för samhället i stort. Många drabbas vilket leder till stort lidande och för samhället höga kostnader. Detta har Professor Peter Apell vid Chalmers University of Technology uppmärksammat. Han har startat upp flera projekt inom området Innovative textiles in healthcare för att hitta nya och bättre lösningar på problem relaterade till vård och hälsa. Det här projektet är ett av de projekt som uppkommit genom hans engagemang. Projektets fokus har varit att undersöka dämpning och spridning av kraft samt energiupptagningsförmåga hos tredimensionell väv i kombination med non woven. Samma typ av undersökning har utförts på ett polymert material kallat D3O. D3O används i nuläget i viss typ av skyddsutrustning men inte inom området höftskydd för äldre. De olika materialens egenskaper har därefter jämförts. Intresset för att undersöka 3D-textil i sammanhanget skyddsmaterial är grundat i att det kan ha flera fördelar i förhållande till de material som används i befintliga skydd idag. Många höftskydd på marknaden har skumgummi som skyddsmaterial. En fördel med textila skydd är möjligheten att producera skydd och hållare för skyddet i ett och samma material vilket förenklar framtida återvinning. Med textila skyddspaneler finns även möjligheten att framställa lätta och flexibla skydd för ökad komfort. Projektets största begränsning har varit testutrustning och testmetoder, en begränsning för hela industrin inom utveckling av höftskydd. Den testutrustning som använts i projektet har varit en fallrigg med tillhörande fallkropp i form av en kula, hos företaget Industritextil Job i Kinna, samt två olika dragprovare med speciellt framtagna hållare och klämmor vid Textilhögskolan i Borås. De textila konstruktionerna som undersökts under projektet har framställts av författarna med hjälp av maskiner och textila material som varit tillgängliga på Textilhögskolan. Flera bindningar togs fram, dessa vävdes och studerades. Två varianter av distansvävar med stående distanser ansågs ha potential tillsammans med två olika konstruktioner av non woven. D3O-materialet köptes in i form av färdiga höftskydd. Projektet har resulterat i att de konstruktioner som tagits fram i väv och non woven har potential men i nuläget troligtvis inte tar upp tillräckligt mycket av kraften för att undvika en frakturskada. Undersökningen har dock visat att det finns mycket att utveckla och forska vidare på inom området 3D-textil. Det polymera skyddet D3O visade goda resultat teoretiskt och praktiskt i den utsträckning det kunde undersökas med tillgänglig testutrustning. Mer arbete med utformning av materialet rekommenderas för att ta fram ett skydd som är bra ur både komfort- och funktionssynpunkt. Det krävs ytterligare tester med bättre anpassad testutrustning innan skyddseffekten kan bekräftas vara tillräcklig. / Hip fractures are a big problem for the elderly in today's society and a problem for our society as a whole. A lot of people get affected by it and it leads to suffering and a large cost for society. This is something Professor Peter Apell at Chalmers University of Technology has noticed. He has started several projects within the field of Innovative textiles in healthcare to find new and improved solutions to issues related to health and welfare. This project is one of the projects started because of his commitment to the cause. The focus of the project has been to explore the attenuation of force, dispersion of force and energy absorption of distance weaves in combination with non woven materials. The same type of exploration has been applied to a polymer material called D3O. D3O is already being used in some types of protective gear but not within the area of hip protection for the elderly. The different materials characteristics have thereafter been compared. The base of the interest in exploring 3D textile protection is that it could provide certain advantages which some of the hip protection products of today lacks. Many of the products today use foam rubber as the base of protection. An advantage with protective panels made by textiles is the possibility that the whole of the protective product can be made in one and the same material throughout which will simplify future recycling. Another advantage with textile protective panels is the possibility of light and flexible constructions for increased comfort. The most influential restriction to the project has been equipment for performing tests on the materials, which is a big restriction in the whole business of developing hip protection. The testing equipment used in this project has been a setup for performing drop testing with a cylindrical impact body, at the company Industritextil Job in Kinna, and two different tensile machines with specially made clamps at the University of Borås. The textile constructions examined during the project has been manufactured with the use of machines and materials available at the Swedish School of Textiles at the University of Borås. Different weaves were constructed, produced and studied. Two of the three dimensional weaves were regarded as having potential if combined with two different non woven structures. The D3O material was bought, readymade, in the form of hip protection panels. The project has shown that the contextures produced have potential but as of now probably is not enough to protect the hip from fracturing. They did show that there is a lot to explore further within the area of 3D-textiles. D3O, showed good results theoretically and practically to the extent possible to test with the available equipment. More work is advised concerning the shape of the protection panel to make it comfortable and effective in its protection. Further testing with other more adapted testing equipment is required before it can be said with certainty that the protective panel reduces applied forces enough for it to avoid a fractured hip.
