Sample UPMSP Vocational Laundry & Dyeing Practice Questions

Try these sample questions to test your UPMSP Vocational Laundry & Dyeing exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the natural source from which natural silk fiber is harvested?

A.Cotton plant seed bolls

B.Silkworm cocoons (Bombyx mori)

C.Flax plant stems

D.Sheep fleece

Explanation: Silk is a natural protein fiber produced by the larvae of the mulberry silkworm (Bombyx mori) when spinning its cocoon.

2Which burning test characteristic is typical of pure cotton fiber?

A.Burns quickly with a yellow flame and smells of burning paper

B.Melts into a hard black uncrushable plastic bead

C.Burns very slowly with a smell of burning hair

D.Self-extinguishes instantly leaving a chemical vinegar odor

Explanation: Cotton is composed of pure cellulose; when burned, it ignites easily, burns with a steady yellow flame, gives off the odor of burning paper, and leaves a soft light-gray ash residue.

3Under which primary category of textile fibers is natural wool classified?

A.Synthetic polymer fiber

B.Regenerated cellulosic fiber

C.Natural protein animal fiber

D.Mineral mineral fiber

Explanation: Wool is classified as a natural protein fiber of animal origin obtained primarily from sheep fleece and consisting mainly of keratin.

4Into which category of stains are blood, egg, and milk stains classified?

A.Tannin stains

B.Grease and oil stains

C.Protein stains

D.Mineral stains

Explanation: Blood, egg, and milk contain organic albuminous proteins and are classified as protein stains.

5Why must cold water be used immediately when washing fresh blood stains from a fabric?

A.Hot water coagulates and sets the albumin protein into fabric fibers

B.Cold water dissolves synthetic dyes out of cotton

C.Hot water converts blood into acidic tannin compounds

D.Cold water acts as a strong reducing bleaching agent

Explanation: Heat causes albumin and globulin proteins in blood to coagulate (denature) and bind permanently to textile fibers. Cold water dissolves the uncoagulated proteins.

6During a flame burning test, what residue and odor are produced by 100% pure wool yarn?

A.Melts into a hard white bead with a celery-like odor

B.Burns rapidly leaving white feathery ash with a paper odor

C.Burns slowly, self-extinguishes, smells of burning hair, and leaves a dark crushable bead

D.Fuses rapidly into a black shiny sphere with a sweet fruity odor

Explanation: Wool is rich in sulfur-containing amino acids (cystine). It burns slowly, self-extinguishes when removed from the flame, smells like burning hair, and leaves an irregular, dark, easily crushable ash bead.

7Which chemical reagent is most effective for removing iron rust stains from cotton garments?

A.Concentrated sodium hydroxide

B.Oxalic acid or dilute hydrofluoric acid solution

C.Glacial acetic acid

D.Acetone solvent

Explanation: Oxalic acid (or dilute hydrofluoric acid) reacts with insoluble ferric oxide (rust) to form soluble iron oxalate complexes, which wash out easily.

8Which chemical solvent will completely dissolve polyester (PET) fibers during laboratory chemical testing?

A.Boiling meta-cresol or hot concentrated sulfuric acid

B.Cold acetone solution

C.5% sodium hypochlorite solution

D.Dilute acetic acid

Explanation: Polyethylene terephthalate (polyester) is resistant to most common solvents but dissolves in boiling meta-cresol (100°C) or hot concentrated sulfuric acid.

9What behavior does Nylon 6,6 exhibit when brought near and into a flame source?

A.Burns without melting leaving gray ash

B.Melts away from flame, burns with a blue flame, smells of celery, and forms a hard round bead

C.Charcoal carbonizes without flame emitting sulfur dioxide gas

D.Explodes into fine carbon soot

Explanation: Nylon is a thermoplastic polyamide. It melts and curls away from flame, burns with a blue flame with light green edges, emits a distinctive celery-like odor, and forms a hard, round, uncrushable gray/black bead.

10Which absorbent reagent is applied to fresh oily grease stains on delicate silk prior to wet cleaning?

A.French chalk (talcum powder) or starch powder

B.Sodium carbonate powder

C.Copper sulfate crystals

D.Bleaching powder

Explanation: Absorbents like French chalk, talcum powder, or cornstarch draw fresh liquid oils out of delicate silk fibers via capillary action without risking water spots or chemical fiber damage.
