Abstract [sv]

Denna rapport beskriver ett examensarbete där optiska fibrer av plast integrerades i varpled i en väv. Syftet med examensarbetet var att undersöka om det är möjligt att industriellt producera ljusemitterande vävar med optiska fibrer. Arbetet delades upp i olika delar, både teoretiska och praktiska. Den teoretiska delen innebar informationssökning inom olika medier, såsom vetenskapliga artiklar och intervjuer med insatta människor inom de berörda områdena. Den praktiska delen i examensarbetet bestod av flera olika moment. Först utfördes en provvävning i en handvävstol, för att finna en lämplig bindning och lära känna materialen. Därefter konstruerades en metod för att testa olika slipmaterial att slipa den optiska fibern med, och utifrån resultaten valdes två slipmaterial ut. Sedan sattes en väv med optiska fibrer upp i en vävmaskin och ett flertal provvävar vävdes. I ett optiklaboratorium skedde sedan mätningar på provvävarnas ljusemittering. Resultatet av mätningarna visade att de optiska fibrerna inte klarade av krökningarna i väven. För mycket ljus läckte ut i krökningarna så väven lyste inte mer än 50 cm. Slutsatsen är att det är fullt möjligt att väva med optisk fiber i varpled, men en bindning där de optiska fibrerna ligger rakt i väven måste konstrueras. In this bachelor thesis has plastic optical fibres been integrated in the warp of a weave. The purpose of the thesis was to make a research if it is possible to produce light emitting weaves with optical fibres in an industrial production. The thesis was divided into several parts, both theoretical and practical. The theoretical part involved taking part of different types of information, such as scientific articles and interviews with knowledgeable people within the related areas. The practical part in this thesis was composed of several different phases. A test weave in a handloom was first performed to find out which weave to use and to understand the materials behaviour. Then a method for testing different materials to grind the optical fibre with was constructed, and out of the results two materials were chosen. After that, a warp with optical fibres was placed into a loom and several prototypes were woven. In an optic laboratory were measurements made on the prototypes’ light emitting ability. The results of the measurements showed that the optical fibres did not cope with the bends in the weave. Too much light emitted out of the bends so the weave only emitted light for 50 cm. The conclusion is that it is possible to weave with optical fibres in the warp, but a new weave where the optical fibres lie straight in the fabric must be constructed.
