Ketchikan Pulp Company

	Ketchikan Pulp Company Ketchikan Pulp Company was a pulp mill located on the north shore of Ward Cove, from Ketchikan, in the U.S. state of Alaska. Owned by Louisiana-Pacific, it operated between 1954 and 1997. It was the last pulp mill to operate in the state. Along with the Sitka pulp mill, the mill was built as part of a U.S. Forest Service economic development program for Southeast Alaska. Ketchikan Pulp Company was originally built as a joint venture between Puget Sound Pulp & Lumber Co. and American Viscose Corporation Over time Georgia Pacific acquired Puget Sound Pulp & Lumber and FMC Corporation acquired American Viscose. Eventually, the company was spun off along with other holdings to form the Louisiana-Pacific Corp., the plant's new owner. KPC was a sulfite process dissolving pulp mill, designed to manufacture a product called "Tongacell," made from cellulose fiber from Spruce and Tsuga trees, which is used in the manufacture of various rayon products. Feedstock for the mill was harveste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pulp Mill A pulp mill is a manufacturing facility that converts wood chips or other plant fiber sources into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods ( kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements. Wood and other plant materials used to make pulp contain three main components (apart from water): cellulose fibres (desired for papermaking), lignin (a three-dimensional polymer that binds the cellulose fibres together) and hemicelluloses, (shorter branched carbohydrate polymers). The aim of pulping is to break down the bulk structure of the fiber source, be it chips, stems or other plant parts, into the constituent fibers. Chemical pulping achieves this by degrading the lignin and hemicellulose into small, water-soluble molecules that can be washed away from the cellulose fibers with ...

picture info	Rayon Rayon is a semi-synthetic fiber, made from natural sources of regenerated cellulose, such as wood and related agricultural products. It has the same molecular structure as cellulose. It is also called viscose. Many types and grades of viscose fibers and films exist. Some imitate the feel and texture of natural fibers such as silk, wool, cotton, and linen. The types that resemble silk are often called artificial silk. The fibre is used to make textiles for clothing and other purposes. Rayon production involves solubilizing cellulose to allow turning the fibers into required form. Three common ways to solubilize are the cuprammonium process, not in use today, using ammoniacal solutions of copper salts; the viscose process, the most common today, using alkali and carbon sulfide; and the Lyocell process, using amine oxide. The last avoids the neurotoxic carbon sulfide of the viscose process but is also more expensive. Rayon and its variants Rayon is produced by dissolving cel ...
