CCT Carpet Fiber Identification & Construction 2

Question 1

Which burn test result indicates a nylon fiber?

Accepted Answer

Melts and fuses, self-extinguishes, smells like celery

Answer

Nylon melts and fuses rather than burning freely, self-extinguishes when removed from flame, and produces a celery-like odor.

Question 2

What distinguishes a Saxony cut pile from a frieze cut pile carpet?

Accepted Answer

Saxony has short, even, upright tufts while frieze has long, highly twisted yarns

Answer

Saxony features short, dense, upright cut pile tufts for a formal look, while frieze has long, highly twisted yarns that curl and hide footprints.

Question 3

A carpet fiber that glows under UV light most likely contains which material?

Accepted Answer

Optical brighteners added to nylon or polyester

Answer

Optical brighteners added to synthetic fibers like nylon and polyester cause them to fluoresce under ultraviolet (black) light.

Question 4

What is the primary advantage of solution-dyed polypropylene (olefin) carpet?

Accepted Answer

Excellent bleach resistance and colorfastness

Answer

Solution-dyeing means the color is built into the fiber during manufacture, making polypropylene highly resistant to bleach and UV fading.

Question 5

Which carpet construction type is most likely to exhibit 'pile reversal' or 'shading'?

Accepted Answer

Cut pile velvet/plush

Answer

Cut pile velvet and plush carpets are most prone to pile reversal (shading/pooling) because the upright fibers can lay in different directions reflecting light unevenly.
