CCT Carpet Fiber Identification & Construction 5

Question 1

Which fiber is most prone to 'wicking' (browning that reappears after cleaning) due to its absorbent nature?

Accepted Answer

Jute or cotton backing fiber

Answer

Jute and cotton backings absorb soil and moisture, which can wick up through the pile as the carpet dries, causing browning or re-soiling at the surface.

Question 2

What is the function of antimicrobial treatments applied to carpet fiber during manufacturing?

Accepted Answer

To inhibit the growth of mold, mildew, and bacteria within the carpet

Answer

Antimicrobial treatments (e.g., Microban) are bonded to fibers to slow or prevent microbial growth, reducing odors and potential health hazards.

Question 3

A 'cut and loop' carpet construction creates its pattern by:

Accepted Answer

Combining areas of cut pile tufts and uncut loop pile tufts at different heights

Answer

Cut-and-loop carpet achieves texture and pattern by combining cut pile (open tops) and loop pile (closed loops) in the same surface, creating geometric or sculptural designs.

Question 4

When identifying an unknown carpet fiber using chemical solubility, which solvent dissolves nylon but not polyester?

Accepted Answer

Formic acid or phenol

Answer

Formic acid (and concentrated phenol) dissolves nylon while leaving polyester largely unaffected, making it a reliable laboratory chemical differentiation test.

Question 5

Which term describes the number of yarn ends (pile yarns) per inch across the width of a tufted carpet?

Accepted Answer

Gauge

Answer

Gauge refers to the spacing of needles across the tufting machine width, expressed as the number of needles per inch, determining how many yarn ends appear across the carpet.
