TECHNOLOGY OF WOVEN FABRIC MANUFACTURE

 LTPC

3003

COURSE OBJECTIVES:
• To enable the students to understand the preparation for weaving and various functions of weaving machine

UNIT I

INTRODUCTION TO WEAVING

5

Yarns quality requirements for high speed automatic shuttle looms and shuttle less loom; warp and weft preparation for high speed looms; Principle of weaving, passage of material, motions in loom – primary, secondary and auxiliary motions, plain power loom driving, timing of motions

UNIT II

SHEDDING MOTIONS

9

Shed geometry and shedding requirement. Types of shed. Shedding mechanisms – positive and negative. Principles of tappet, dobby and jacquard shedding mechanisms, reversing mechanismslimitations of various shedding mechanisms; Conventional and modern dobby and jacquard mechanism


UNIT III

WEFT INSERTION AND BEAT UP

9

Shuttle picking and checking mechanisms, shuttle flight and timing; Weft feeder – types, Principles of weft insertions in shuttle less looms; mechanism of weft insertion by projectile, rapier loom and jet – air and water. Multi-Phase weaving systems; Kinematics of sley, sley eccentricity; beat up mechanism in modern looms;

UNIT IV

SECONDARY AND AUXILARY MOTIONS

13

Take up and let – off motions used in plain power looms; cloth formation, weaving condition – factors and control; warp protector and warp and weft stop motion; plain power loom accessories. Automatic weft replenishment in shuttle looms – pirn changing and shuttle changing looms; mechanisms involved in automatic pirn changing – feelers, cutters, design of shuttle, three try motions; multi shuttle looms- box changing principle, Automatic pirn changing in multi shuttle loom. Weft arrival control and automation in shuttle less looms; selvedges in shuttle less looms; quick style change;

UNIT V

PROCESS CONTROL & SPECIAL WEAVING PROCESSES

9

Techno economics of shuttle less loom weft insertion systems; loom monitoring and control Loom stoppages and efficiency; fabric defects and value loss; fabric shrinkage in the loom – causes and control; fabric engineering. Filament weaving – Silk & Texturised yarns. Principles and mechanisms in weaving Pile fabrics, tapes and triaxial fabrics

TOTAL: 45 PERIODS
