Asahi Kasei develops cellulose/pulp nonwoven.Asahi Kasei has developed a nanofiber nonwoven non·wo·ven adj. Made by a process not involving weaving. Used of textiles. n. Material or a fabric made by a process not involving weaving. containing cellulose cellulose, chief constituent of the cell walls of plants. Chemically, it is a carbohydrate that is a high molecular weight polysaccharide. Raw cotton is composed of 91% pure cellulose; other important natural sources are flax, hemp, jute, straw, and wood. and pulp. The fiber diameter is less than 100nm and the pore pore (por) a small opening or empty space. alveolar pores openings between adjacent pulmonary alveoli that permit passage of air from one to another. size is less than 100nm, allowing the mass per unit area to be lower than 10 gsm. The company uses pulp fibrillation fibrillation /fi·bril·la·tion/ (fi?bri-la´shun) 1. the quality of being made up of fibrils. 2. a small, local, involuntary, muscular contraction, due to spontaneous activation of single muscle cells or muscle to make the diameter of the fiber less than 100nm. Asahi has been marketing nanofiber-based nonwovens based on bacterial cellulose but they present problems associated with productivity and cost. Therefore, the cellulose nanofiber nonwovens are more suitable for commercialization. |
