Characteristics of Natural Fiber

Because our floor coverings are woven from Natural Fibers, they have normal irregularities that are considered part of their charm. Variations in weave and shading, for example, create a distinctive, interesting character that makes natural fiber floor coverings unique. What you won’t find anywhere is a perfect natural fiber floorcovering.







Expect these common irregularities:

Fibers that have been tied off during the manufacturing process.
Some Irregularity in the Ribs

Some fibers, such as seagrass and hand woven jute, are short fibers. During handling, they sprout. Clipping sprouts is recommended.






Variation in Loop Size
Woven Carpets made of natural fibers may have some irregularity in the yarns, which can create the appearance of a variance in loop size (warp or weft yarns). Variations of either thick or thinner yarns within 50% of normal are allowed.









Shedding of Loose Fibers
A natural result of the process used to create carpets and rugs. When a rug is produced, it goes through a combing process, which helps remove short and broken fibers. However, some of these fibers fall onto the surface of the pile and appear as “fluff”. The effect can vary depending on material type.

Irregularity in the Ribs
Some will be closer together, some farther apart.

Pattern Ribs
Ribs of a pattern can be horizontal or vertical due to the size of the rug or material. In some areas, backing may not extend to the edges of the rug to achieve an exact size.

Slight Bowing
Industry allows up to 2% bowing on our natural fiber broadloom carpet and bordered area rugs. Due to construction and the nature of the fiber, the following collections have bowing tolerances over 2% and require customer approval before shipping: Kochi, Cheena®, Cheyenne, and Zira.

Slightly out of Square
Rugs can be slightly out of square due to the natural imperfections of the roll.

Jumping Ribs
Rugs will be cut as square as possible, and may require ‘jumping ribs’. This is not a border application error.

Color Changes
All natural fibers eventually return to their original colors. Bleached products darken over time, and colored fibers fade. Avoid direct sunlight.

Color variance
Showroom samples may not match current inventory. Roll differences are more significant with natural fibers than with synthetic ones. Material from different rolls seldom turn out to be exactly the same color.

Striation or color variance lines are normal in all natural fiber carpet and rugs because color variances occur naturally in nature.

Foreign Yarns
Contamination can occur when fibers from previous production find their way into the current yarn. This is due to the nature of the fiber, collection process, and weaving process. Foreign yarn is common in all natural fiber products.

Expansion and Contraction
The hydroscopic nature of natural fibers means that they adjust to environmental conditions. They’re constantly moving! If broadloom (wall-to-wall) floor covering is purchased, it should be loose-laid for 24 hours in the room in which it will be installed, and at the temperature it will typically experience. This will let the fibers get used to their new surroundings. Customers often try to install carpeting as soon as they get it, only to find that they have to tell the installer to come back 24 hours later. To help avoid this situation, please review Fibreworks’ How to Put a Carpet in Its Place brochure with your customers or visit The Carpet and Rug Institute web site at for a comprehensive view of most issues concerning carpet installation.

Visible Installation Seams
Especially in patterns that are difficult to seam (e.g. Herringbone, Panama and Diagonal).

Customer’s Responsibility
It is your responsibility to inspect the goods before any cutting, fabrication or installation occurs. Under no circumstance will an allowance be made after the goods have been altered.

Residential Use
Natural fiber products are recommended for residential use only unless otherwise specified.

For Indoor Use Only
Natural Fibers should not be used in areas where moisture is present or ventilation is inadequate.
