   Abstract : Efforts to address environmental concerns have resulted in new regulations designed to plan the reduction of plastic and synthetic polymer usage, necessitating the search for sustainable natural alternatives with comparable cost-effectiveness and mechanical performance. Thermomechanical pulp (TMP) fibres are one of the most affordable natural fibres that have no chemical refining in production, production have a high yield of 90-98% and TMP fibres have been demonstrated to improve the mechanical characteristics (strength, stiffness and toughness) of wood-polymer composites (WPCs) compared to the pure polymer.

   Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

6. 4. Textile Sound Design

   Author : Margareta Zetterblom; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; The Cresson Institute; Textile design; acoustics; phenomenography; sound environment; sound absorbing textiles; Pierre Schaeffer; phenomenology; interactive textile design; textile sound design;

   Abstract : There are a number of ways to describe the aesthetical expression of a textile, but how is it possible to express its sound affecting qualities? This thesis aims at developing conceptual and methodological tools in order to adapt sound within the textile design area. Occupational groups working with sound are to a large extent problem driven.
