Overview[ edit ] Paper made from wood-based pulp that has not had its lignin removed turns yellow, becomes brittle, and deteriorates over time. During production, acid-free paper may be treated with a mild base usually calcium or magnesium bicarbonate to neutralize the natural acids occurring in wood pulpand it may also be buffered to prevent the formation of additional acids as may develop from the application of sizing. The bicarbonate is added in excess, to supply the paper with an alkaline reserve to provide protection from further attack by acids remaining in the paper or supplied by the environment e. PCC reacts with acids, and therefore requires the pulp to be chemically neutral or alkaline.
The acidity will transfer to adjacent objects causing these objects to become weaker and possibly discolored. Acid free tissue papers are especially processed to remove such contaminants.
Some acid free papers are, in addition, buffered to an alkaline pH. These buffered papers are considered acceptable for cotton or linen textiles, but potentially harmful to silk or wool objects.

Therefore, it is suggested that a neutral pH, unbuffered acid free tissue paper be purchased for general textile or costume storage. An 18 pound weight paper is useful for quilts, coverlets, and the storage of other flat textiles. For storing costumes or other items, some "stuffing" or interleaving may be necessary to maintain a three dimensional shape or to prevent abrasion between textile surfaces.
For these purposes, a lighter 12 pound paper is suggested. This lighter acid free paper is also known as "laminating tissue.
A roll of paper is economical and easier to store than flat sheets if a quantity of textiles needs to be packed for storage or if the textiles are larger than 32" x 40".
