Section 11.1—quiz: Carpet Construction

The part of the carpet that you see and walk on is called the pile. The pile refers to the surface of the carpet, which is made up of loops or cut fibers. It is the visible and tactile component of the carpet that provides comfort and aesthetic appeal. The primary backing, backsize, and secondary backing are all layers underneath the pile that provide support and stability to the carpet.

Jute is a natural fiber that is known for its durability. It is commonly used as a primary backing in various products, including carpets and rugs. Jute provides strength and stability to the product, making it suitable for heavy use. Unlike other options like backsize and polypropylene, jute is a natural material that is environmentally friendly. Additionally, jute has good moisture resistance and helps to prevent mold and mildew growth. Therefore, jute is the correct answer for a durable, natural primary backing.

The density of the carpet's face fibers should be recommended as the best indicator of a carpet's durability. Higher density means that there are more fibers packed closely together, making the carpet more resistant to wear and tear. This helps the carpet maintain its appearance and withstand heavy foot traffic for a longer period of time.

By bending a corner of the carpet and observing how much backing shows underneath the pile, Louis can determine the density of each carpet's face fibers. If a significant amount of backing shows, it indicates that the face fibers are less dense and may not be as durable. On the other hand, if little to no backing shows, it suggests that the face fibers are tightly packed and therefore more durable. This method allows Louis to assess the durability of the carpet samples without the need for complex equipment or measurements.

A thinner carpet pad should be recommended by the executive housekeeper to avoid the problem of shifting carpet due to heavy loads. A thicker carpet pad might actually exacerbate the problem by providing more cushioning and allowing the carpet to move more easily. A thinner carpet pad would provide less cushioning and stability, making it more difficult for the carpet to shift under heavy loads.

Polypropylene is the correct answer because it is a synthetic material that is known for its mildew-resistant properties. It is commonly used as a primary backing in carpet manufacturing because it helps to prevent the growth of mildew and mold. This synthetic material is durable and resistant to moisture, making it an ideal choice for areas that are prone to dampness or high humidity.

Secondary backing is an optional component that can help to increase the life of a carpet. While primary backing provides the foundation for the carpet, secondary backing is an additional layer that is added for extra durability. It helps to reinforce the carpet and prevent it from stretching or tearing over time. By adding a secondary backing, the carpet is better able to withstand heavy foot traffic and regular wear and tear, ultimately extending its lifespan.

The primary backing for the face fibers of a carpet is not the pad over which the carpet is installed. The primary backing is a layer of fabric or material that holds the face fibers in place and provides stability to the carpet. The pad, on the other hand, is a separate layer that is placed underneath the carpet for cushioning and support.

Backsize is the correct answer because it is the bonding material that holds carpet fibers in place. Backsize is typically applied to the back of the carpet during the manufacturing process and helps to secure the fibers in position, preventing them from shifting or coming loose. This material plays a crucial role in maintaining the integrity and durability of the carpet.
