Q.1097: Why cotton is used in paper?
Ans. Cotton is one of the strongest and most durable 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. Generally, given reasonable care, you can expect one year of usable life for every 1% of cotton contained in the sheet. Paper made with 100% cotton content can be expected to live at least 100 years.
