Tree-free paper. Tree-free paper, also known as no tree paper, offers an alternative to traditional wood-pulp paper [ 1] due to its unique raw material [ 2] composition. This type of paper is considered more eco-friendly especially when evaluating its entire life cycle . Sources of fiber for tree-free paper[ 3][ 4][ 5]
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses, or other vegetable sources in water, draining the water through a fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets ...
Wood-free paper is paper created exclusively from chemical pulp rather than mechanical pulp. [1] Chemical pulp is normally made from pulpwood, but is not considered wood as most of the lignin is removed and separated from the cellulose fibers during processing, whereas mechanical pulp retains most of its wood components and can therefore still be described as wood.
Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products .
Wood fibre. Wood fibres (also spelled wood fibers, see spelling differences) are usually cellulosic elements that are extracted from trees and used to make materials including paper . The end paper product (paper, paperboard, tissue, cardboard, etc.) dictates the species, or species blend, that is best suited to provide the desirable sheet ...
Woodfree uncoated paper ( WFU ), uncoated woodfree paper ( UWF) or uncoated fine papers are manufactured using wood that has been processed into a chemical pulp that removes the lignin from the wood fibers and may also contain 5–25% fillers. [ 1] Both softwood and hardwood chemical pulps are used and a minor part of mechanical pulp might be ...
Hemp paper. Hemp paper is a paper variety consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin ...
Papermaking. A sheet of fibres which were just collected from the liquid suspension with the screen. The next steps are to press it and to dry it. The Diamond Sutra of the Chinese Tang dynasty, the oldest dated printed book in the world, found at Dunhuang, from 868 CE. Papermaking is the manufacture of paper and cardboard, which are used widely ...
