Top 10 Questions for Viscose Department Worker Interview

1. Explain the process of viscose fiber production?

Viscose fiber production involves the following steps:

• Pulping: Wood pulp is produced by chemically dissolving the lignin, which binds the wood fibers together.
• Steeping: The pulp is treated with sodium hydroxide solution to form cellulose alkali.
• Pressing and Shredding: The cellulose alkali is pressed to remove excess solution, then shredded into crumbs.
• Aging: The crumbs undergo aging under controlled temperature and humidity to mature the cellulose.
• Dissolving: The aged crumbs are dissolved in carbon disulfide to form viscose solution.
• Spinning: The viscose solution is forced through spinnerets into a coagulating bath to form filaments.
• Stretching and Washing: The filaments are stretched to align the cellulose molecules, then washed to remove impurities.
• Drying and Crimping: The fibers are dried and crimped by passing them through hot air and rollers.

2. Describe the different types of viscose fibers and their uses?

There are several types of viscose fibers, each with unique properties and uses:

Regular Viscose

• Strong, absorbent, and drapes well.
• Used in textiles, clothing, household fabrics.

Modal

• Soft, smooth, and has a silky feel.
• Used in bedding, underwear, sportswear.

Tencel

• Biodegradable, environmentally friendly.
• Used in clothing, upholstery, home textiles.

Lyocell

• Strong, wrinkle-resistant, and moisture-wicking.
• Used in clothing, sportswear, medical textiles.

3. What are the key quality parameters for viscose fibers?

The key quality parameters for viscose fibers include:

• Tenacity: Breaking strength of the fiber.
• Elongation: Ability of the fiber to stretch before breaking.
• Modulus: Stiffness of the fiber.
• Absorbency: Ability of the fiber to absorb moisture.
• Opacity: Level of light transmittance through the fiber.
• Whiteness: Brightness and purity of the fiber.

4. How do you control the quality of viscose fibers during production?

Quality control during viscose fiber production involves various measures:

• Raw material inspection: Checking wood pulp for impurities and consistency.
• Process monitoring: Monitoring temperature, pH, and other parameters throughout the production process.
• Fiber testing: Continuously testing fiber samples for tensile strength, elongation, and other quality parameters.
• Statistical process control: Using statistical methods to identify and minimize variations in fiber quality.
• Corrective actions: Implementing corrective actions when quality deviations occur.

5. What are the common defects in viscose fibers and how can they be prevented?

Common defects in viscose fibers include:

• Weak spots: Caused by uneven distribution of cellulose molecules.
• Thick and thin spots: Resulting from variations in nozzle diameter or spinneret temperature.
• Fibrillation: Splitting of the fibers.
• Yellowing: Caused by aging or exposure to sunlight.
• Odor: Unpleasant smell due to residual sulfur compounds.

These defects can be prevented through proper process control, maintenance of equipment, and use of additives.
