  1. 1. Chemical and physical changes in PET fibres due to exhaust dyeing : Issues in thermo-mechanical recycling of dyed PET textiles

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Frida Lindström; [2018]
    Keywords : Polyethylene terephthalate; polyester; exhaust dyeing; auxiliary chemicals; degradation; hydrolysis; thermo-mechanical recycling; fibre-to-fibre recycling; FTIR; DSC; tensile properties; demand absorbency test.;

    Abstract : Polyethylene terephthalate (PET) is the most used fibre in the textile industry. PET is also used in other products, e.g. soft-drink bottles and food packaging. READ MORE

  3. 2. Dissolution and fibre spinning of cellulose from an ionic liquid

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Erika Andersson; [2018]
    Keywords : Cellulose; scattering; ionic liquid; dissolution; regenerated cellulose fibre; structure-property relationship; materials chemistry; materialkemi; Chemistry; Technology and Engineering;

    Abstract : Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. READ MORE

  4. 3. Textile Actuator Fibres : Investigation in materials and methods for coiled polymer fibre muscles

    University essay from Akademin för textil, teknik och ekonomi

    Author : Rebecca Melvinsson; [2015]
    Keywords : Textile actuators; Soft robots; Coiled muscles; PVDF; SMP; Fibre Anisotropy; Thermal actuation; α-relaxation;

    Abstract : This thesis contains an investigation in materials and methods for coiled polymer muscles where the end application in mind is to be integrated in a textile structure such as an exo-skeleton glove. Previous artificial muscle fibres have proved little success due to performance, cost and scalability. READ MORE

  5. 4. Magnetoconductiivity of icosahedral AIPdRe at temperatures between 50-250 Kelvin

    University essay from KTH/Material- och nanofysik

    Author : Sana Ullah; [2013]
    Keywords : ;

    Abstract : The electrical conductivity of icosahedral Al70:5Pd21Re8:5 samples with residual resistance ratio RRR = p(4:2K)=p(295K), in the range from 10 to 220 are reported. The samples were manufactured by melting in an arc furnace and then annealed at 940 °C. One of the samples (RRR=10) was made by melt spinning. READ MORE

  6. 5. Magnetism of Nanocrystallized Amorphous Fe75B10Si15

    University essay from KTH/Materialvetenskap

    Author : Arnab Chakraborty; [2012]
    Keywords : amorphous metals; nanocrystalline materials; magnetism; soft magnetic material;

    Abstract : Amorphous ribbons of alloy composition Fe75B10Si15 are cast by melt spinning and annealed to partially nanocrystalline states. The magnetic properties are investigated by VSM and MTGA. Structure is examined using XRD and SEM. READ MORE
