purified cotton linters cellulose sheets, (Whatman filter papers No.1)

Ingredients

cotton linters

Evidence

"In the study, purified cotton linters cellulose sheets, (Whatman filter papers No.1; 86.0 g m-2, degree of polymerisation (DP): 2630, RSD 0.74%) were used for applying inks."

Remarks

The paper has a degree of polymerisation (DP) of 2630. It was used as a model substrate to observe long-term effects of inks via accelerated ageing at 105 degrees Celsius for 24 days (p. 41). The degradation causes depolymerization of cellulose, which affects the stability of fibers and causes breakages (p. 28).
