Lesson 13 : Chemical Spinning

Introduction

Man-made and synthetic fibres are filamentous in form as their manufacturing process can be controlled at any stage unlike natural fibres. All synthetic fibres are produced from polymers. These are in solid form at room temperature often available in the form of chips/particles of one to two millimeters. The solid state of the polymer needs to be altered in order to reshape them to get the desirable shape. This is possible only when the solids are transformed into liquid form. The ‘free flowing’ polymer liquids are extruded through fine holes to form thin and long filament fibres.
