Spinning - Hats

Japanese: 紡糸 - ぼうし

An operation in which a substance with fiber-forming ability (mainly a chain-like polymeric substance) is put into a molten state or solution and passed through the holes in a spinneret to form threads. There are three main types: (1) Melt spinning. A spinning method in which a polymeric substance is melted and discharged into air, gas, or a suitable liquid, where it is cooled and solidified. Used for nylon, Tetoron, etc. (2) Dry spinning. A spinning method in which a solution of a polymeric substance is extruded into heated air and the solvent is evaporated to obtain fibers. Used for acetate rayon, Oron, etc. (3) Wet spinning. A spinning method in which a solution of a polymeric substance is extruded into a suitable liquid and solidified. Used for viscose rayon, vinylon, etc. The material of the spinneret is a gold-platinum alloy for viscose rayon, and nickel or stainless steel for others. →Spinning→Related topics Regenerated fibers | Cuprammonium rayon

繊維形成能を有する物質（主として鎖状高分子物質）を溶融状態または溶液とし，紡糸口金の細孔を通して糸状にする操作。次の３種に大別。（１）溶融紡糸。高分子物質を溶融し，空気中，ガス中，または適当な液体中に吐出して冷却固化させる紡糸法。ナイロン，テトロンなどに利用。（２）乾式紡糸。高分子物質の溶液を加熱空気中に押し出し，溶媒を蒸発させて繊維を得る紡糸法。アセテートレーヨン，オーロンなどに利用。（３）湿式紡糸。高分子物質の溶液を適当な液体中に押し出して凝固させる紡糸法。ビスコースレーヨン，ビニロンなどに利用。紡糸口金の材料は，ビスコースレーヨン用では金‐白金合金，その他はニッケルまたはステンレス鋼など。→紡績
