Market demands
� Product safety
� Hygienic application
� FDA approved or components listed
� Processability
� Throughput
� Technical performance
� Functionality
� Bonding behavior
� Influence to the surface haptic
10
Market requirements
� Environmental value
� Sustainable / Green brands
� Environmental friendly
/ carbon food print
� Economical value
� Energy consumption
� High efficiency
11
Challenges
� Fibre grades based on PLA IngeoTm
� Processability of the raw material (melt spinning process / conventional stretch line)
� Reach the expected fibre properties
� Further processing during the web forming
� Conversion to the final product
12
Challenges of PLA IngeoTMMMM
� Lower melting point compared to PET (160°C / 253°C)
� Lower glass transition temperature compared to PET (60°C / 78°C)
� Requires modified spinning and stretching conditions compared toPET
� To get similar crimp properties, crimping conditions need to be adjusted
13
Challenges
� Important fibre properties
� Fineness
� Finish on the fibre
�crimp contraction (K1)
� Crimp
�crimps / cm (crimps / inch)
decrimped length – crimped length
