Preview Questions Textile Chemist | Role Specific Skill

Question 1: How does UV resistance in textiles generally work?

Which action should you take?

Choose only one option

By using UV-absorbing agents like benzotriazoles

By using high-density weave fabrics

By applying a special coating that reflects UV light

By increasing the fiber's tensile strength

Question 2: What is the major limitation of using disperse dyes on cellulose fibers?

Which action should you take?

Choose only one option

Low affinity for cellulose fibers

Poor wash fastness

Poor light fastness

Limited range of available colors

Question 3: How do you "achieve optimal dye penetration" for blended fabrics using different fibers?

Which action should you take?

Choose only one option

By pre-treating the fabric with appropriate chemicals, optimizing dyeing conditions, and choosing dyes that work well with all fibers in the blend

By applying higher dye concentrations to improve penetration

By ignoring fiber composition and using the same dye type for all blends

By assuming that blended fabrics behave uniformly during dyeing

Question 4: What is the main difference between reactive and pigment dyes in terms of washfastness?

Which action should you take?

Choose only one option

Reactive dyes bond with fibers through covalent bonds.

Reactive dyes have lower washfastness.

Pigment dyes are more chemically stable.

Pigment dyes are not suitable for cotton fabrics.

Question 5: How does "polymer degradation" affect textile performance and longevity?

Which action should you take?

Choose only one option

It guarantees improved texture and feel

It eliminates the need for finishing processes

It speeds up fabric dyeing

Polymer degradation can weaken fibers, reduce colorfastness, and impair functionality, especially under UV exposure

Question 6: How do you "synthesize copolymers" to enhance both the strength and flexibility of textile fibers?

Which action should you take?

Choose only one option

By using only flexible monomers and assuming they will provide necessary strength

By increasing monomer concentration without considering compatibility

By focusing solely on monomer type and ignoring molecular weight

By selecting compatible monomers that provide both rigid and flexible segments in the copolymer backbone
