  1. 16. PEDOT Coated Viscose Fibers by Optimized OCVD Process : Washing and Stretch Sensing Properties

    Magister-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :MAJID ALI; [2013]
    Nyckelord :Viscose yarn; conductive polymers; PEDOT; ferric III chloride; ferric tosylate p-toluene sulfonate ; stretch sensors;

    Sammanfattning : Electroactive textile fibers are key components in smart and interactive textile applications. In previous research on textile base conductive fibers, viscose fibers were coated with poly (3,4-ethylenedioxythiophne) (PEDOT) using oxidative chemical vapor deposition (oCVD) technique[1].

  3. 17. Rheological study of cellulose dissolved in aqueous ZnCl2 : Regenerated cellulosic fibres for textile applications

    Master-uppsats, Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Louise Ulfstad; [2013]
    Nyckelord :Rheology; cellulose dissolution; ZnCl2;

    Sammanfattning : The most known regenerated cellulosic fiber is viscose, produced in a wet spinning process, but due to cost and environmental issues other processes have been developed. Lyocell fibers, produced in air-gap spinning, have superior dry and wet strenght and a lower environmental impact compared to viscose. LÄS MER

  4. 18. Viscose production : Impact from alkali resistance (R18) and hemicellulose content in dissolving cellulose on the processability and quality of viscose.

    Uppsats för yrkesexamina på avancerad nivå, Kemiska institutionen

    Författare :Sara Hellström; [2012]
    Nyckelord :Viscose;

    Sammanfattning : In this study the influence of variations in alkali resistance (R18) of cellulose on the quality of the viscose product in terms of carbohydrate content have been examined. The dissolution pattern of hemicellulose in the first steps of the viscose process with different running parameters has been determined. LÄS MER

  5. 19. High rate biogas production from waste textiles

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Karthik Rajendran; Gopinath Balasubramanian; [2011]
    Nyckelord :biogas; waste textiles; nmmo-pretreatment; two-stage anaerobic digestion; UASB; CSTR;

    Sammanfattning : Textile is a global product used by all people in the world. These textiles after the use are thrown into the trash for incineration or land filling. However an efficient way that can be used to produce more energy, in an environmentally friendly process is anaerobic digestion. Waste textiles which contain cellulosic fibers (e. LÄS MER

  7. 20. Impact of degree or Polymerization of Fiber on Viscose Fiber Strength

    Magister-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Shoaib Iqbal; Zuhaib Ahmad; [2011]
    Nyckelord :viscose; viscose fiber; fiber strength; degree of polymerization; dp; regenerated fiber; regenerated cellulose fiber;

    Sammanfattning : The aim of the study was to find out the relationship between the DP and the tensile properties of different regenerated cellulose fibers. During the process to make regenerated cellulose fibers from wood, the reduction in DP of cellulose is a necessary process to enable fiber extrusion. LÄS MER
