• Wicking: Measuring the ability of a fiber to absorb and transport moisture.
• Pilling: Evaluating the tendency of a fabric to form small, entangled balls on its surface.
• Fade resistance: Testing how well a fiber retains its color when exposed to light or other environmental factors.

4. Explain the role of fiber morphology in determining the properties of a fabric?

• Fiber length: Longer fibers produce stronger, more durable fabrics.
• Fiber fineness: Thinner fibers improve softness and drape.
• Fiber shape: Cross-sectional shape affects fabric texture and handle.
• Fiber orientation: Arrangement of fibers in a fabric influences properties such as strength and elasticity.

5. Describe the different methods of fabric construction, such as weaving, knitting, and nonwovens?

Weaving

• Interlacing vertical (warp) and horizontal (weft) yarns to create a grid-like structure.
• Produces durable, stable fabrics with a wide range of textures.

Knitting

• Looping yarns together to create a flexible, elastic fabric.
• Produces soft, breathable fabrics for clothing, sportswear, and home textiles.

Nonwovens

• Bonding fibers together without using traditional weaving or knitting techniques.
• Produces lightweight, disposable fabrics for applications such as wipes, surgical gowns, and insulation.

6. Explain the principles of dyeing and printing on textiles?

Dyeing

• Immersing fabrics in a dye solution to absorb color.
• Factors affecting color include dye type, temperature, pH, and time.

Printing

• Applying color to specific areas of a fabric using screens, rollers, or ink-jet technology.
• Techniques include direct printing, transfer printing, and digital printing.

7. Discuss the challenges and advancements in sustainable fiber production?

Challenges

• Environmental impact of natural fiber production (e.g., water consumption, pesticide use).
• Limited availability and high cost of sustainable synthetic fibers.

Advancements

• Development of eco-friendly natural fiber processing techniques.
