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
