Crêpe paper
Encyclopedia
Crêpe paper is tissue paper
that has been coated with sizing
and then creped to create gathers.
that is creped is produced on a paper machine
that has a single large steam-heated drying cylinder (yankee) fitted with a hot-air hood. The raw material is paper pulp. The Yankee cylinder
is sprayed with adhesives to make the paper stick. Crêping is done by the Yankee's doctor blade that is scraping the dry paper of the cylinder surface. The crinkle (crêping) is controlled by the strength of the adhesive, geometry of the doctor blade, speed difference between the yankee and final section of the paper machine and paper pulp characteristics.
Crêpe tissue paper comes in white, as well as an array of bright and pastel colors, and it may or may not bleed.
The crêpe ratio reflects how much the paper has shortened during crêping. The figure is normally between 10 - 30 %. Crêping is used to adjust the paper's stretch and thickness, both of which have a marked effect on softness and absorbency.
Crêping can also be applied to specialty papers, such as microcrêping in sack paper

A Yankee dryer is a pressure vessel used in the production of tissue paper. On the Yankee dryer, the paper goes from approximately 42–45% dryness to just over 89% dryness. In industry, MG cylinders or Yankee dryers are primarily used to remove excess moisture from pulp that is about to be converted...
