double-side coated fibre synthetic paper

Ingredients

selected pulp, polyamide (PA), polyester (PES), special binder system

Preparation Steps

Original Recipe Text

This is a composite fibre paper manufactured from a blend of cellulose pulp and synthetic polymers (Polyamide and Polyester). The structure is double-side coated and stabilized with a proprietary binder system (p. 83).

Evidence

"Paper 2: Pretex (manufacturer: Neenah-Lahnstein Company, Germany) is a double-side coated fibre synthetic paper made from a mixture of selected pulp and synthetic fibres (polyamide – PA and polyester – PES) in a combination with a special binder system."

Remarks

Paper 2 is more thermally stable than pure cellulose papers. It exhibited good light fastness due to the inclusion of pigment colors and lack of optical brighteners (p. 86). However, dry-heat ageing significantly impacted its folding endurance, dropping from 3543 double folds to 1807 after 12 days (p. 92). Its Yellowness Index (YI) was recorded at 4.3 (unaged) (p. 88). ATR-FTIR analysis revealed a decrease in absorption in the region 1550-1000 cm–1 after ageing, specifically at the 1400 cm–1 band (p. 94-95).
