Question 1: Define the term 'woven fabric' and describe how it is constructed verbally.

Answer: A woven fabric is created by interlacing two sets of yarns at right angles. The yarns running lengthwise are called warps, and the yarns crossing them are called wefts or fillings. The interlacing occurs on a loom, resulting in a stable fabric.

Question 2: Explain the main difference between woven and knitted fabrics in terms of their construction.

Answer: Woven fabrics are made by interlacing yarns at right angles on a loom, creating a firm, stable fabric. Knitted fabrics are made by looping yarns together, which makes them more stretchable and flexible.

Question 3: Describe the construction process of a felt fabric verbally.

Answer: Felt is produced by matting, condensing, and pressing fibers together, usually wool fibers. This process involves applying heat, moisture, and agitation to cause the fibers to interlock without weaving or knitting.

Question 4: Sketch a simple diagram showing the basic construction of a plain weave fabric. Label the warp and weft yarns.

Answer: A correct sketch would show vertical lines representing warp yarns and horizontal lines for weft yarns crossing over and under the warp yarns in an alternating pattern. The labels should clearly state 'Warp' and 'Weft'.

Question 5: List three advantages of using a knitted fabric over a woven fabric.

Answer: Knitted fabrics are more stretchable, more comfortable to wear, and less likely to fray at the edges because of their looping structure.

Question 6: Describe verbally how a pile fabric, such as velvet or terry cloth, is constructed.

Answer: Pile fabrics are woven with additional yarns that create loops or cut ends on the surface, forming a plush, textured surface. The pile yarns are either woven into the fabric or inserted afterward through a process called tufting.

Question 7: Sketch a diagram of a simple jacquard weave pattern and include annotations to show the intricate design process.

Answer: A correct sketch would depict a complex woven pattern with different colored yarns creating an elaborate design, with annotations indicating the use of a jacquard loom to control individual warp yarns for detailed patterns.

Question 8: Explain how the construction of a non-woven fabric differs from woven or knitted fabrics.

Answer: Non-woven fabrics are made by bonding fibers together using heat, adhesives, or mechanical entanglement, without weaving or knitting. They are produced directly from fibers or filaments rather than yarns.

Question 9: Draw a cross-sectional diagram of a fabric made using the knitting technique. Indicate the loops' arrangement.

Answer: A correct diagram would show interconnected loops aligned in rows, with each loop passing through the one below, illustrating the chain-like nature of knitted fabric loops.

Question 10: Describe verbally what effect the construction method has on the stretch and durability of fabrics.

Answer: Knitted fabrics tend to be more elastic and stretchy due to their looped structure, which allows the fabric to stretch and recover. Woven fabrics are generally more durable and less stretchy because of their interlaced yarns, providing stability.
