ITI Weaving Technician Syllabus (English)

Course Overview

Trade Name: Weaving Technician
Duration: 1 Year (2 Semesters)
NSQF Level: Level 4
Eligibility: 10th Grade Pass with Science and Mathematics
Objective: To train candidates in operating and maintaining weaving machinery for producing fabrics, preparing them for roles as weaving technicians, loom operators, or self-employment in textile production and design services.
Certification: National Trade Certificate (NTC) by NCVT

Trade Theory

Introduction to Textile Industry: Overview of weaving, types of fabrics (cotton, silk, synthetic), textile industry scope.
Safety Practices: PPE (gloves, earplugs, masks), machine safety, fire hazards, first aid in textile units.
Fibre and Yarn: Natural fibres (cotton, wool), synthetic fibres (polyester, nylon), yarn properties (count, twist).
Weaving Preparatory Processes: Warping, sizing, beaming, drafting; their role in fabric production.
Loom Types: Handlooms, power looms, shuttle looms; components (warp beam, heddles, shuttle).
Weaving Fundamentals: Plain weave, twill, satin; shed formation, picking, beating-up.
Basic Maintenance: Lubrication, cleaning looms, checking belts and pulleys.

Trade Practical

Safety Drills: Wearing PPE, practicing emergency stops, using fire extinguishers.
Yarn Handling: Identifying yarn types, measuring yarn count, checking twist direction.
Warping Practice: Preparing warp beams, aligning threads uniformly (±1 mm accuracy).
Loom Setup: Threading heddles, tying warp ends, adjusting tension on power looms.
Weaving Tasks: Operating handlooms to produce plain weave fabric (1x1 m).
Maintenance Work: Cleaning loom parts, oiling bearings, inspecting shuttle condition.
Project Work: Weave a 2x1 m cotton fabric sample with plain weave, ensuring even selvedge.

Hours: Theory: 160 hours | Practical: 240 hours

Trade Theory

Advanced Weaving Techniques: Dobby, jacquard looms; producing complex patterns (herringbone, damask).
Automatic Looms: Rapier, air-jet, water-jet looms; automation features, productivity benefits.
Fabric Defects: Causes of defects (broken ends, slubs, mispicks), quality control methods.
Textile Calculations: Warp/weft density, fabric weight, production rate calculations.
Electrical Systems: Motors, sensors in automatic looms; basic troubleshooting.
Environmental Practices: Waste yarn recycling, water conservation in sizing, eco-friendly dyes.
Entrepreneurship: Starting a weaving unit, market trends (e.g., sustainable fabrics).

Trade Practical

Dobby Weaving: Setting up dobby looms, weaving twill patterns (2x1 m fabric).
Automatic Loom Operation: Operating rapier looms, adjusting pick density (±2 picks/cm).
Defect Analysis: Inspecting fabric for defects, correcting issues like loose ends.
Quality Control: Measuring fabric GSM (grams per square meter), checking weave consistency.
Electrical Maintenance: Checking motor connections, replacing loom sensors.
Eco Practices: Recycling waste yarn, optimizing water use in sizing process.
Project Work: Produce a 3x1 m jacquard fabric with a custom pattern, ensuring defect-free output.

Hours: Theory: 160 hours | Practical: 240 hours
