UPMSP Intermediate Dyeing Art study plan

Define the three colour attributes (hue, value, chroma) and use them to describe six given shade samples in writing

Classify the seven dye classes in the syllabus by their fibre affinity and application method, building a one-page comparison table

Explain the difference between substantivity, affinity and exhaustion using a worked numerical example

Distinguish a dye from a pigment and state two industrial consequences of that difference

Describe the chemical structure and dyeing behaviour of cotton, wool, silk, polyester and nylon, listing the ionic or hydrophobic sites each offers to dye

Match each of the seven dye classes to the fibres it can practically dye, and justify two pairings that look surprising

Explain why reactive dyes form covalent bonds with cellulose and why that raises wash fastness

Identify which fibres require a carrier or high-temperature dyeing for disperse dyes and state why

Trace the chemistry of reactive dyeing of cotton step by step, naming the role of salt, alkali and temperature at each stage

Explain the reduction and oxidation stages of vat dyeing and why the leuco form is water-soluble

Describe how acid, basic and direct dyes attach to their substrates, contrasting ionic bonding with hydrogen bonding and van der Waals forces

Distinguish the roles of mordants, assistants, levelling agents, wetting agents and sequestering agents, giving one concrete example of each

Explain the azoic (naphthol) dyeing sequence and why the coupling step must follow impregnation

Compare yarn, hank, package, jigger and winch dyeing by liquor ratio, mechanical action and suitable substrate

Explain why package dyeing needs controlled flow reversal and what happens to levelness if flow is one-directional

Describe the jigger sequence for woven fabric, including how the fabric is turned and how shade is built in passes

Select the correct assistant for three stated problems (hard water, uneven strike, poor wetting) and justify each choice

Calculate a liquor ratio and a percentage shade recipe from given weights of goods and dye

Explain the resist mechanism in bandhani, batik and tie-dye, and state how each method differs in where the resist sits

Describe the sequence of block printing on dyed cloth, including colour paste preparation and registration

List three printing faults (bleeding, uneven impression, colour smudging) and their causes

Explain why a printed good needs steaming or curing after printing and what happens if it is skipped

Compare direct, discharge and resist printing styles in one sentence each

Define wash, rub, light, perspiration and sublimation fastness and name the principle behind testing each

Explain how a grey scale is used to grade change in colour and staining, and interpret a grade of 4-5

Identify the process variables (temperature, time, pH, electrolyte, liquor ratio) that most affect levelness and fastness

Describe three causes of patchy or unlevel dyeing and the corrective action for each

Explain what a control sample and a standard shade card are used for in a dyehouse

List the personal protective equipment needed when handling alkali, reducing agents and dye powders, and state the hazard each item addresses

Describe safe storage and labelling practice for dyes and auxiliary chemicals in a small workshop

Explain first-aid response for skin contact with alkali and for inhalation of dye powder

Describe routine maintenance and calibration checks for a dye bath, balance and pH meter

Outline how dyehouse effluent should be handled before discharge, naming the main concerns

Re-derive the dye-class-to-fibre map from memory and check it against your week-2 matrix

Solve five mixed numerical problems on shade percentage, liquor ratio and dye uptake without notes

Answer ten rapid-fire definition questions on colour theory, mordants and fastness, scoring your own accuracy

Review every weak point flagged in weeks 1-7 and write a corrected one-line rule for each
