Preview Questions Textile Chemist | Role Specific Skill

Question 1: How does "stretch and recovery" testing influence the quality of stretch fabrics in fashion?

Which action should you take?

Choose only one option

It guarantees better color retention

It eliminates the need for elastic fibers

Stretch and recovery testing evaluates how well a fabric can return to its original shape after stretching, ensuring durability

It reduces the time required for fabric finishing

Question 2: How do you "determine the moisture regain" of a fabric and why is it important for apparel?

Which action should you take?

Choose only one option

By using a moisture regain tester that measures the weight difference before and after conditioning

By assuming moisture regain is not significant for garment performance

By measuring fabric weight without adjusting for moisture content

By ignoring environmental conditions and focusing only on fiber composition

Question 3: How does "silicon finishing" improve the properties of textile fabrics?

Which action should you take?

Choose only one option

Silicon finishing enhances the fabric's softness, luster, and drape, improving the appearance and feel of the fabric

It guarantees longer-lasting color

It increases fabric shrinkage

It reduces the time required for dye fixation

Question 4: How do textile chemists address the challenge of achieving color fastness in natural fibers like cotton?

Which action should you take?

Choose only one option

By applying a final wash after dyeing that improves color retention.

By using lower concentrations of dye to reduce fading.

By using mordants and ensuring proper dye fixation techniques to bind the dye molecules to the fiber.

By using only synthetic dyes that offer better fastness.

Question 5: How do you "control polymer chain length" during the production of textile fibers to achieve specific mechanical properties?

Which action should you take?

Choose only one option

By focusing on cost reduction without considering polymer chain length

By assuming all polymers will behave similarly regardless of chain length

By adjusting polymerization time, temperature, and solvent conditions to control chain length

By increasing polymer concentration and assuming chain length will adjust automatically

Question 6: How do you "control the reactivity of dyes" in textile dyeing to ensure consistent color results?

Which action should you take?

Choose only one option

By adjusting dyeing conditions such as pH, temperature, and the use of appropriate carriers and auxiliaries

By relying on a single dye type without adjusting for fabric behavior

By increasing dye concentration to ensure full absorption

By applying dyeing agents at high temperatures without considering the fabric type
