Abstract

Provided is a process for preparing a smooth and glossy surfaced paper web. The process comprises subjecting the paper web to shear by using calender rolls driven at different speeds or calender rolls with different diameters. The resulting paper has a totally different structure than the original paper, as it has a much smaller void structure and a much higher degree of bonding between the elements of the sheet. The process is particularly applicable to improving the electrical insulation properties of an aramid paper web.

Claims (4)

1. A process for preparing a paper web having a glossy surface, with the paper web being subjected to sufficient shear by at least two calender rolls to create a glossy surface on the paper web, with four calender rolls being used in a nested configuration to impart the shear, the nested configuration comprising three large calender rolls surrounding a singly smaller calender roll in the center of the three larger calender rolls.

2. The process of claim 1 , wherein the paper is subjected to shear at ambient temperatures.

3. The process of claim 1 , wherein the paper web subjected to shear is comprised of aramid fibers.

4. The process of claims 3 , wherein the paper web subjected to shear further comprises aramid fibrid.
