NEOCEL

Novel processes for sustainable cellulose-based materials

Summary

As the world’s population increases, it needs more textiles. A source with great potential for long term increase in production volumes are man-made cellulosic fibres.

The NeoCel project will develop innovative and techno-economically feasible processes for producing high quality textile fibres from reactive high cellulose pulps. It will enhance the use of cellulose from sustainable sources, with a special focus on textiles.

NeoCel will reduce the environmental impact and occupational health issues relating to man-made cellulose fibre production and promote sustainably produced, good quality man-made cellulosic fibres for the textile and fashion industries.

Description

Objectives: 
  • To develop innovative and techno-economically feasible alkaline processes for sustainable production of high quality textile fibres from reactive highcellulose pulps in connection to pulp mills.
  • Enhance the use of cellulose from sustainable sources for material applications with special focus on textiles
  • Reduce the environmental impact and occupational health issues related to man-made cellulose fibre production
  • Promote the availability of sustainably produced, good quality man-made cellulosic fibres for textile and fashion industry
Expected impacts: 
  • Developing regenerated cellulose textile fibres with lower environmental impact than any other type of existing textile fibre. The developed fibres to be highly cost competitive due to at least 15% lower production cost compared to standard viscose.
  • To strengthen the market position of regenerated cellulose fibres for textile application by an expected reduction of production cost of at least 15% for the developed process in the project. The market share is expected to increase to 15% even if the total market for textile fibres is also expected to strongly increase.
  • Achievement of strength properties in the range of cotton and outperforming standard Asian viscose: novel regeneration chemistries in the first spin bath enabling both improved recovery of dope chemicals and facilitating prolonged stretching leading to higher strength and addition of strength increasing compounds.
  • Competitive production of regenerated cellulose fibres by system integration with the pulp mill, energy optimisation, recovery/regeneration of chemicals and better use of pulp mill side streams.
