  2. 1. An Experimental Study of Fancy Yarn Formation in Rotor Spinning

    Author : Jan Kwasniak; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : FANCY YARN is a yarn with deliberate imperfections. Strange as it may appear, in present times when defect-free yarn is considered to be a premium product, fancy yarns, with all their imperfections, are also in demand. It is a different matter that the volume production of fancy yarn is insignificant in comparison to the normal yarn production. READ MORE

  4. 2. Conducting Foams and Fibres for Bulk Plastic Thermoelectrics

    Author : Jason Ryan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanocomposites.; e-textiles; renewable energy; conducting yarn; thermoelectrics; conjugated polymers; organic thermoelectrics; electronic textiles; polymer foams; conducting fibres;

    Abstract : The use of small portable electronics in society is constantly increasing, thus the demand for portable power sources also rises in turn. Portable electronic devices rely upon energy stored in batteries to power them, which in turn require regular access to power outlets to be recharged. READ MORE

  5. 3. Testing and analysis of composites with 3D woven reinforcement

    Author : Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D weave; finite element; manufacturing; yarn path; weaving; failure criteria; mechanical testing; 3D väv; finita element; tillverkning; trådbanor; vävning; brottkriterier; mekanisk provning; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. READ MORE

  6. 4. Exploring fully integrated textile tags and information systems for implementing traceability in textile supply chains

    Author : Vijay Kumar; Högskolan i Borås; []
    Keywords : Traceability; Textile; Yarn coding; Integrated tag; Supply chain management; Spårbarhet; Textil; Garn‐kodning; Integrerad märkning; Hantering av försörjningskedjor; Textil och mode generell ; Textiles and Fashion General ;

    Abstract : Exploring fully integrated textile tags and information systems for implementing traceability in textile supply chainsTraceability, in general, refers to keeping track of information to a certain degree. The concept of traceability is considered important to verify the various aspects of products in different industries and their global supply chains. READ MORE
