Methods and apparatus for vacuum forming a beverage carrier yoke are described. The yoke comprises a number (e.g., four or six) collars interconnected by a web, and each collar exhibits dimensionsincluding a nominal diameter and a substantially uniform thicknessselected to improve strength and increase comfort. The yoke is produced using a slurry comprising a moisture barrier and a fiber base.

A method of increasing chemical efficiency of chemical additives in a papermaking system includes the steps of providing thick stock pulp comprising soluble lignin, process water, and at least about 2% by weight of cellulosic fiber based on total weight of thick stock pulp, and adding at least one organic polymer to the thick stock pulp to reduce the amount of soluble lignin therein. The organic polymer is chosen from cationic polymers, non-ionic polymers and combinations thereof.

The invention relates to transfer paper for sublimation printing, comprising a fibrous substrate, said transfer paper having one or more cationic agents on at least one face thereof, deposited on the fibrous substrate by means of surface treatment, the amount of cationic agent(s) being greater than or equal to 8% by dry weight of the total dry weight of the compound(s) added to the fibrous substrate by means of the surface treatment.

According to an example aspect of the present invention, there is provided a method comprising: providing a web comprising fibrous material; applying a first binder composition in the form of a foamed composition onto the web; and subsequently applying a second binder composition onto the web; wherein the second binder composition has a higher solids content than the first binder composition.
