3- FABRIC TECHNOLOGY Summary of Chapter 3: Enter
Fabrics act as support material for dirt and interact with it. The relationships established with dirt depend to a large extent on the physical structure of fabrics and the chemical composition of the textile fibres.
THE FIBRE THE YARN HILO THE FABRIC THE STRUCTURE OF A FABRIC:
FABRICS Woven Fabrics On a loom With a single yarn Unwoven fabrics Felting Needle punching TYPES OF FABRICS:
THE YARN: DEFINITION: A narrow, cylindrical, and flexible body of indefinite length. The yarn is produced by joining and twisting an ordered group of fibres or filaments, giving it its characteristics of flexibility and strength. CHARACTERISTICS Composition: Nature of the fibres, fineness, etc. Structure: number of plies Thickness Twist: direction and number of turns Bulkiness Evenness Fuzziness PROPERTIES Resistance to traction Elasticity: Resistance to elongation Resistance to abrasion Friction coefficient
