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

Answer: A woven fabric is made by interlacing two sets of yarns at right angles; the vertical yarns are called warp, and the horizontal yarns are called weft. The fabric is produced on a loom where the warp threads are held under tension and the weft is woven through them.

Question 2: List three common types of weave used in fabrics and briefly describe each.

Answer: Plain weave: the weft alternates over and under each warp thread, creating a simple criss-cross pattern. Twill weave: the weft yarn passes over one or more warp yarns and then under the same number, creating a diagonal pattern. Satin weave: the weft yarns float over multiple warp yarns before going under one, resulting in a smooth face with fewer interlacings.

Question 3: Explain the difference between knitted and woven fabrics in terms of construction and stretch properties.

Answer: Knitted fabrics are made by interlooping yarns, creating a flexible and stretchable fabric. Woven fabrics are made by interlacing yarns at right angles, resulting in a less stretchy but more stable fabric.

Question 4: Describe how a satin weave fabric is constructed and one characteristic it has as a result.

Answer: A satin weave is constructed by floating the weft yarns over multiple warp yarns before passing under one, creating long floats on the surface. This results in a smooth, lustrous fabric with a shiny face.

Question 5: Sketch a simple diagram showing a plain weave pattern. Label the warp and weft yarns.

Answer: A correct sketch would show a grid pattern with alternating over and under interlacing yarns. The vertical lines are the warp, and the horizontal lines are the weft, crossing at right angles.

Question 6: Identify two advantages and two disadvantages of woven fabrics.

Answer: Advantages: Woven fabrics are durable and have a stable structure. They can be made in various weights and textures. Disadvantages: They tend to fray at the edges and are less flexible compared to knitted fabrics.

Question 7: Draw a diagram of a basic knitted fabric showing the interlocking loops. Indicate the direction of the yarns.

Answer: A correct diagram would show a series of interlocking 'V' shapes (loops) aligned horizontally, with arrows indicating the yarns' direction as they form the interlocking loops.

Question 8: Explain how the construction of a pile fabric differs from that of a plain woven fabric.

Answer: Pile fabrics are constructed with additional yarns that create a raised surface, such as loops or cut ends, giving the fabric a textured surface. Examples include velvet and terry cloth, which have extra warp or weft yarns that form the pile.

Question 9: Describe the properties of a fabric made with a twill weave and give an example of such a fabric.

Answer: Twill weave fabric has a diagonal rib pattern, is durable, and drapes well. An example is denim, which is made using a twill weave and is known for its strength and durability.

Question 10: Explain why the choice of fabric construction is important in the design of a garment.

Answer: The construction determines the fabric's properties such as stretch, durability, drape, and appearance. Choosing the appropriate construction ensures the garment functions well, looks attractive, and is comfortable for the wearer.
