Sizing also contributes to the crisp, unique feel of cotton fiber papers.
How the sizing is introduced to the paper will affect the finished characteristics of the sheet.
Paper with a p H factor of “7″ or higher is considered acid free. Without sizing, when ink is applied to the surface of the sheet, it will bleed through the fibers causing a blurred look.
back to top SIZING: All cotton fiber paper is sized at some point in the manufacturing process. Size seals the fibers and helps control the degree of ink penetration into the paper.
The very best grade of sulphite is known as a #1 sulphite.
Southworth uses only #1 sulphite in the manufacturer of its fine business paper.back to top COTTON FIBER: Cotton is one of the strongest and most durable natural fibers known to man.Papers manufactured from cotton fiber will last longer and hold up better under repeated handling and various environmental conditions than paper made from wood pulp.This is done by incorporating a special marker into the watermark.The position of the mark is usually changed annually and legal records are kept documenting the date and its exact location.The watermark generally will identify the manufacturer, the brand name and the amount of cotton fiber, if any, in the sheet.Through the use of a special roller called a “dandy roll”, the watermark is impressed inside the paper early in the manufacturing process.Papers that are “acid free” will resist yellowing and disintegration longer than sheets that are not acid free.This is particularly true as the percent of wood pulp in paper relative to the amount of cotton increases, since cotton fiber papers are less likely to disintegrate or yellow than papers made with all or part wood pulp.Generally, given reasonable care, a customer can expect one year of usable life for every 1% of cotton contained in the sheet.Typically cotton fiber papers are made of either all cotton fiber (100% cotton) or a blend of cotton and wood pulp.
