Production
Paper is made from either virgin or recycled paper pulp which is extracted from wood or fiber crops. They are sometimes bleached during the production process to make the color more white. It is not uncommon for rolls of paper towels to include intricate colored images on each square (such as flowers or teddy bears). Resin size is used to improve the wet strength. Patterns of shapes such as circles or diamonds are often imprinted into the paper towels to help it hold moisture. Manufacturers use the pattern of the material, microscopic spaces within the pattern, and a type of cellulose in the fibres in order to maximize absorption. Most rolls are manufactured with two layers of paper, but different types can have more layers. They are classified by their key properties such as strength, absorbency, weight, and thickness. Paper towels are packed individually and sold as stacks, or are held on a continuous roll. Colored paper towels were introduced 30 years ago and come in two distinct classes, domestic and institutional. A 2007 study shows the consumption of paper towels and other tissue products is highest in the United States of America at around 24 kilograms per capita, with consumption higher than in Europe, and more than 500 times higher than in Latin America.

Famous quotes containing the word production:
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
“... if the production of any commodity necessitates the sacrifice of human life, society should do without that commodity, but it can not do without that life.”
—Emma Goldman (1869–1940)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
