Non-woven production enhancement developments

Group work result

Otaniemi 29.9.2010

main objective of fubio unchanged
Main objective of FuBio (unchanged)
  • The main objective of FuBiois to establish, in Finland, a world-leading competence platform in the field of wood biorefinery R&D
    • Focus of FuBio: Novel value chains, in which wood is refined into new materials & chemicals
    • A competence platform comprises many attributes, like people, business concepts, processing technologies, R&D and testing facilities, networking, etc.


product group non woven production enhancement related business possibilities
Product group: Non Woven: production enhancement / related business possibilities

Describe the refining chain (i.e. set of processes) from cellulose pulp to the selected product group (dissolution or partial dissolution of cellulose is a must)

process 1, process 2, process 3, xx

Generate a “light road map” of what must be done (bottlenecks) in order to make the selected refining chain ready for commercial production-scale


Identify the role of the new FuBio program in trying to remove these bottlenecks (Note: A SHOK programs is not removing all the hurdles)


In respect to the FuBio tasks (previous question), identify where the Forestcluster partners do not have competences (= cooperation needs)



group work discussions
Group work discussions
  • What limits the usage of viscose fiber?
    • Strength
    • Processability
    • Water absorption
    • Fiber dimensions enhancements
  • Possibilities of bi-component fibers?
  • Cellulosic based fiber coating technologies / binders that are environmentally sound
  • We should take time and understand the current and future needs better
  • What are the limiting factors of using products that are in the pipeline
    • Nanowhiskers
    • Long cellulose particle like “polymerstack” type of products


group work discussions1
Group work discussions
  • Non dissolving products’ usability in current processes?
  • Fiber based carrying surfaces?
  • Non water soluble approaches
  • What is between pulp and dissolution? Ways to use the product “in between”
  • Different products need different fibers
    • Flexibility and easy fiber modification as a competitive advance?
  • Properties that compete and can replace synthetic fibers and cotton need to be developed
  • Possible new non-woven technologies that overcome the deficiencies of viscose fiber
  • Cheap solutions for bulk markets for dissolving pulp or viscose applications
  • Cost out vs. Value in approach


group work discussions2
Group work discussions
  • Replacement of harmful chemicals from non woven production
  • New properties like anti bacterial fibers for certain markets
  • Other industry applications that non woven
    • Micro crystalline cellulose usage GE products as an example?
    • Screens, semiconductors, colors with cellulose crystals
  • MCC applications outside of current fields
  • More energy efficient viscose fibers / or production to match
  • Improved line speeds with improved products
  • Mixture optimization possibilities for non woven
  • Possibilities in thermal bonding
    • Bicomponents / other solutions
    • Cellulose acetate coatings


summary of the work group
Summary of the work group
  • There are huge amount of non woven production technologies
    • The WP should aim at certain focused alternatives
  • Value in and cost out are both possible targets for various WP’s
  • Substitution economics approach to replace oil and cotton based alternatives
    • Market potential is huge (Ahlstrom uses 8% currently)
  • Enhanced fiber properties and functionalities seem to have interesting opportunities



Planning process

  • Identifying the most important market possibilities in non woven applications
    • Opportunity recognition
    • Air laid, carded, spun bond, melt blown, wet laid: which is the most interesting market
  • Fiber development options for better process ability or functionality
    • Better strength, diversity in fiber properties, enhanced features (unique selling point development)
  • New production technology development that matches / compensates the deficits
  • Totally other uses, like GE usage of NCC
  • Working projects on special applications to match with these identified needs
  • Projects should be divided into cost out vs. value added
