Course Outcomes:
Students will be able to achieve & demonstrate the following COs on completion of course based learning
- Use the beam warping machine to produce a warper beam with releavant process parameters.
- Use the sectional warping machine to produce the required warp pattern in the weaver’s beam.
- Prepare size paste for given yarn type and count.
- Produce the weaver’s beam by setting the relevant process parameters of the sizing machine.
- Use quality checking parameters to ensure the required quality of sized yarn.
Unit I
Principles of Direct Warping 1.1 Objectives and significance of warping process, Types of warping, and importance of each: Beam warping, sectional warping, single-end warping, ball warping, Differentiate between various warping processes. Criteria of selection of sectional warping and beam warping process. Types of yarn packages: overend withdrawal and side withdrawal. 1.2 Direct warping: Passage of yarn through the direct warping machine. Creels: Types, merits, and demerits of each, Tensioners: necessity and types. 1.3 Headstock components: Stop motion- its significance on the quality of the beam, Expanding comb and their types, Pressure drum, Doffing-manual and automatic, Defects in warping beams- uneven density, ridges, bulged or sunken selvages, nonuniform length. 1.4 Calculation: Production, Number of beams in a set, Number of ends in a beam, efficiency from given parameters.

Unit III
Preparation of Size Paste 3.1 Sizing ingredients and their role: adhesive, softeners, Antiseptics, Weighing agent, Wetting agent. Antistatic agent, Deliquescent agent, defoaming agent, etc. Traditional sizing components used in India process (IKS). Adhesives: Classification of adhesives, physical properties of starch, Factors governing formulation of size paste 3.2 Size paste preparation: mixer, pressure cooker, storage, and transport to the size box. Cooking of size paste in a pressure cooker, injection cooker. 3.3 Size paste properties and their significance: Keeping, congealing, viscosity, and concentration. Testing of adhesives: Microscope method, Fineness, Viscosity, Moisture content, Ash content, Cold soluble matter. Chalk-Board Presentations Video Demonstrations Site/Industry Visit
Unit IV
Sizing Machine and Its Components 4.1 Passage of yarn through two-cylinder and multicylinder sizing machine. Creel types: Horizontal creel or over and under creel, Vertical creel: top withdrawal and bottom withdrawal, Inclined creel: top withdrawal and bottom withdrawal, Equi-tension creel, Magazine creel, Merits and demerits of each. Leasing of warp. The braking system creels the number of warp beams required for given fabric parameters. 4.2 Size box, its components, and their role: conventional and modern size box, immersing roller, Squeezing roller, Temperature controlling devices-thermostat tube, Size paste control system, Electrical system. Wet splitting and its advantage. 4.3 Importance of Drying. type of drying: cylinder, hot air, radiative. Mechanism of drying in the cylinder. Factors affecting the rate of drying on cylinders. comparing 2-cylinder and multicylinder drying. Dry splitting arrangement 4.4 Function of headstock components: comb, Sheeting roller, Drag roller, Driving arrangement: Muti-motor drive, Reeves/PIV gear drive, Measuring and marking motion Presentations Site/Industry Visit Video Demonstrations
