Chapter 1– Introduction §1-1 Preface / 序论 §1-2 The tasks in yarn manufacture / 纱线制备任务 §1-3 Main spinning systems / 主要纺纱系统 §1-4 What we learn ? / 课程主要任务 §1-1 Preface 1、The objects of spinning： stable fiber =＞spinning system =＞single yarn=＞plied yarn Yarn clasification ★ Regular yarn monofiber、fiber straightness and parallelization honogeneneous fiber distribution、 honogeneneous linear density and twist distribution honogeneneous color and low impurities ★ Filament yarn： original filament、twisted filament and textured yarn(变形丝) ★ fancy yarn (花式纱线)：color and structure ★ composite yarn(复合纱)： core-spun yarn(包芯纱)、 cover spun yarn(包缠纱)、tubular yarn(空芯纱) Stable fiber / short fiber Natural fiber: cotton、 wool、 bast fiber (ramie, flex, Apocynum, hemp, jute)、 silk、bamboo； Regenerated fibers: Viscose 、 model、lyocell、tencel、 milk fiber、soybean fiber、chitin、 Cellulose acetate Synthetic fiber： PET 、 PA 、 PAN、 PLA 、Pu Inorganic fiber: carbon/graphite、 ceramic 、 metal spinning system：纺纱系统 2、Spinning technology is very important 2.1 Yarn structure and properties are important factor affecting fabric quality and style. 2.2 Spinning engineer is only method to convert stable fiber to yarn. 2.3 It is one of methods of fabric design and development. 2.4 Spinning engineer take an important role in textiles economy. 自由端纺纱:环锭纺纱=＞紧密纺纱=＞喷气纺纱 =＞赛络纺纱,赛络菲尔纺纱,缆型纺纱 Open end spinning: ring spinning=＞compact spinning=＞air-jet spinning =＞sirospun, sirofilspun, solospun 非自由端纺纱=＞转杯纺纱,摩擦纺纱,涡流纺纱,喷气涡流纺纱 Nonopen end spinning=＞rotor spinning, friction spinning, vortex spinning, air jet and vortex spinning §1-2 The tasks in yarn manufacture 1、main problems to be solved in spinning process （1）the difference between fiber material and single yarn ＝＞ main problems to be solved in spinning process （2） the difference between single yarn and plied yarn ＝＞ main problems to be solved in spinning process （1）
