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
