Free RRT Carpet Construction & Inspection Questions and Answers

Question 1

What is the primary purpose of a carpet's primary backing?

Accepted Answer

To hold the yarn tufts in place during construction.

Answer

The primary backing is the foundational layer of a carpet into which the yarn tufts are inserted during the manufacturing process. Its essential purpose is to securely hold these yarn tufts in place, preventing them from pulling out and ensuring the carpet's structural stability. This initial layer is critical for the overall construction and durability of the carpet.

Question 2

Which of the following carpet construction methods is known for its durability and dense pile?

Accepted Answer

Tufted carpet

Answer

Tufted carpet is the most common and versatile carpet construction method, known for its efficiency and ability to produce a wide range of styles. It achieves its durability and dense pile by mechanically inserting yarn tufts into a primary backing. This method allows for a robust and resilient carpet suitable for various applications, making it a popular choice.

Question 3

What does 'face weight' measure in a carpet?

Accepted Answer

The weight of the carpet fibers per square yard.

Answer

Face weight measures the actual amount of yarn or fiber material in the carpet pile, specifically the weight of the fibers per square yard, excluding the backing. It is a crucial indicator of carpet quality and durability. A higher face weight generally signifies a denser, more luxurious, and more resilient carpet that can withstand more wear and tear.

Question 4

Which fiber type is most resistant to stains and moisture?

Accepted Answer

Nylon

Answer

Nylon is widely regarded as the most durable and resilient synthetic carpet fiber available. It possesses excellent resistance to stains, abrasion, crushing, and moisture, making it ideal for high-traffic areas. Its strong molecular structure allows it to maintain its appearance and bounce back from compression better than most other fiber types.

Question 5

What is the purpose of a carpet's secondary backing?

Accepted Answer

To reinforce the carpet and lock tufts in place.

Answer

The secondary backing is applied to the underside of the carpet after the primary backing and tufts are in place. Its main purpose is to provide additional stability, reinforce the primary backing, and securely lock the yarn tufts even further. This layer significantly contributes to the carpet's overall durability, dimensional stability, and resistance to delamination.
