Preview Questions Textile Chemist | Role Specific Skill

Question 1: How does "polymer crystallinity" affect the processing of textile fibers?

Which action should you take?

Choose only one option

Higher crystallinity results in stronger and more heat-resistant fibers, which are harder to dye

It guarantees softer fabrics

It eliminates the need for polymer blending

It reduces the cost of raw materials

Question 2: What is the impact of "acetate fibers" on dyeing properties compared to "nylon fibers"?

Which action should you take?

Choose only one option

It guarantees superior dye penetration

It increases fabric shrinkage

It eliminates the need for dye heat setting

Acetate fibers absorb dyes differently, often requiring specific formulations, whereas nylon tends to absorb disperse dyes better

Question 3: What role does UV degradation play in the development of outdoor and sports textiles?

Which action should you take?

Choose only one option

UV degradation strengthens fabric properties and prevents wrinkles.

UV degradation causes fabric to become stretchier and more breathable.

UV degradation causes fiber breakdown, leading to fabric weakening, so UV inhibitors are incorporated to improve longevity.

UV degradation has no impact on outdoor textiles.

Question 4: What is the effect of enzyme treatment on cellulose-based fibers in textile processing?

Which action should you take?

Choose only one option

It causes fabric to become brittle and prone to tearing.

It reduces the fabric's ability to absorb moisture.

Enzyme treatment enhances softness, brightness, and dye uptake while removing impurities.

It increases the tensile strength of the fabric.

Question 5: What is the purpose of the hydrophilicity test in textile testing?

Which action should you take?

Choose only one option

To measure the fabric's ability to resist flame.

To determine the fabric's resistance to UV radiation.

To measure the fabric's durability during wear.

To measure the fabric's ability to absorb water, impacting comfort and performance.

Question 6: Which of the following factors most significantly impacts the pH level of textile processing?

Which action should you take?

Choose only one option

The fiber content of the textile.

The temperature of the water used for dyeing.

The type of chemicals and dyes used during the finishing process.

The length of the fiber processing cycle.
