The fibers may be chemically modified, like in viscose or cellophane.  In recent years materials scientists have begun exploring further use of these fibers in  composite materials. Fiber crops are generally harvestable after a single growing season, as  distinct from trees, which are typically grown for many years before being harvested for  wood pulp fiber. In specific circumstances, fiber crops can be superior to wood pulp fiber in  terms of technical performance, environmental impact or cost. There are a number of issues  regarding the use of fiber crops to make pulp. One of these is seasonal availability. While  trees can be harvested continuously, many field crops are harvested once during the year and  must be stored such that the crop doesn't rot over a period of many months. Considering that  many pulp mills require several thousand tonnes of fiber source per day, storage of the fiber  source can be a major issue. Botanically, the fibers harvested from many of these plants are  bast fibers; the fibers come from the phloem tissue of the plant.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783845405278\"\u003e\u003ch3\u003eWorld Fiber Crops\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783845405278","offer_id":39471284224093,"sku":"9783845405278","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/fbf79c28-b43b-49ee-a6c5-21ef97d115bd.jpg?v=1757742063","url":"https:\/\/shop.autorenwelt.de\/products\/fiber-crops-von-qurban-ali-assistant-muhammad-ahsan-und-ihsan-khaliq","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
