Non woven production enhancement developments

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
