Preview Questions Textile Chemist | Role Specific Skill

Question 1: How do "cross-linked polymers" impact fabric performance in textiles?

Which action should you take?

Choose only one option

Cross-linked polymers enhance the fabric's dimensional stability, durability, and resistance to wear

They reduce dye uptake

They increase the fabric's tendency to shrink

They reduce the fabric's colorfastness

Question 2: Which chemical process is commonly used to improve the water repellency of fabrics?

Which action should you take?

Choose only one option

Ammonia treatment

Alkaline scouring

Acidic washing

Fluorocarbon treatment

Question 3: Which chemical is commonly used to improve the dye fixation rate in cotton fabrics?

Which action should you take?

Choose only one option

Sodium acetate

Potassium permanganate

Urea

Sodium carbonate

Question 4: How do you "optimize the dye uptake" in polyester fibers through polymer modification?

Which action should you take?

Choose only one option

By modifying the polymer structure to introduce polar functional groups that improve dye affinity

By ignoring polymer structure and focusing solely on dye type

By using the same polymer structure for all dye types

By increasing the molecular weight without considering dye absorption

Question 5: In textile chemistry, what is the effect of using a higher concentration of a mordant during dyeing?

Which action should you take?

Choose only one option

It improves color intensity and fixation

It makes the fabric more resistant to washing

It lowers the fabric's tensile strength

It makes the fabric water-repellent

Question 6: What is the impact of using too high a concentration of hydrogen peroxide during bleaching?

Which action should you take?

Choose only one option

It enhances fabric strength and color

It may lead to fabric damage and weakening

It makes fabric more resistant to dyeing

It speeds up the bleaching process without damage
