Fiber Shape & Modification Ratio
The shape of the fibers in a carpet’s yarn system is important because it affects the carpet’s appearance and performance – including how long the carpet can be expected to last, how easy it will be to clean, and how well the fibers will resist soil and dirt.
The fiber modification ratio – calculated on the cross-sectional shape of the carpet fiber – contributes to these soil-hiding properties as well as longevity and overall performance.
What is modification ratio?
Modification ratio estimates a fiber’s performance, using a mathematical calculation based on the roundness of the fiber. The rounder the fiber, the lower the modification ratio, and the better the carpet will perform.
Modification ratio is calculated by comparing the outer circumference of the fiber to the circumference of the inner circle. The smaller the ratio, the more soil resistant the fiber will be and the better the carpet will wear. The larger the ratio, the more likely the fiber will trap and hold soil and the carpet might experience premature pile crush or matting.
Consider Modification Rates Based on Traffic
The preferred modification rate (MR) for medium to high traffic areas = <2.2
The preferred MR for high to very high traffic areas = <1.5
The fibers in ShadowFX carpet tile have a modification ratio of 1.5 – 2.1.
By comparison, carpet-mill extruded Type 6 Nylon has a ratio of as much as 4.7.
ShadowFX Premium-branded fibers key to durability and long-lasting beauty.
Why premium fibers?
Mill-extruded fibers are value-engineered for mill profitability and process expedience. Since fibers are the building blocks of a robust carpet tile, this is the wrong place to cut corners.
Appearance and longevity rely heavily on the quality and shape of the individual fibers. In a 24/7 space like a 9-1-1 call center, durability and longevity are mandatory. Replacing the carpet because it no longer looks good would be like closing a Los Angeles highway during rush hour to repair a roadway built with fragile concrete.
How do you know if a fiber is carpet-mill-extruded?
It’s easy: for starters, mills making their own fibers use their own carpet mill brand names for describing the nylon. Example XYZ Mill Premium Branded Nylon.
What if modification ratio info is missing from a suppliers literature?
You should ask for this information from the manufacturer. It is readily available. If they won’t supply the information or claim that modification ratio is not relevant to your project, you might ask yourself why they would conceal a fact that is readily available from premium-branded fiber manufacturers like Universal, Invista and Aquafil.
Here’s a real example of the use of Modification Ratio taken from a flooring specification for a government healthcare project in Indiana:
Face Fiber: 100% Nylon, Premium Branded by Invista, Universal or Aquafil. All fibers must have a modification ratio of 2.5 or less. Fibers extruded by carpet mills will be considered “unbranded” for purposes of this standard.
Passing the Test
We go beyond standard wear testing with our proprietary ART – Appearance Retention Test.
ART is the only test of its kind to simulate real world usage for 1 year, 5 years, 10 years or more.
To illustrate the superior performance of the fibers we use, we ran a 10 year wet and dry ART test on ShadowFX carpet with a fiber modification ratio of less than 2.0, along with a competitive product made with fibers with a modification ratio of greater than 2.5.
See the cross section of each fiber and the before and after images of the length of the fibers. Notice the abrasion and breakdown of the fiber in the competitive product.
ShadowFX Floating Floors
ShadowFX Static-dissipative (SC) Carpet Tile Collections
Looking for easy installation of Staticworx ESD Carpet Tile over your bare access floor panels?
ShadowFX SDC with TacTiles® is your solution.
- Installation economy - no adhesive required
- Guaranteed to meet all ESD standards for any application
- ShadowFX carpet tiles with dissipative backing are grounded upon contact with metal panels
Carpet tiles are easily lifted and replaced
With its simple, subtle texture and diversity of color options, Shadow FX SDC Solids is a popular choice for many styles of interior. It’s also ideal for mixing and matching with other Shadow FX SDC carpet tiles, to create accents, inserts, borders or checkerboard effects – a really useful, versatile tool for designers.
After two or three years of use, carpet tiles exposed to chair casters and heavy traffic used to be prone to pile crush, making them look different from adjacent tiles. The main factor contributing to this problem was the pattern designs used in typical ESD carpet tile. All of these systems were either a solid pattern with slightly mottled colors or linear patterns with directional lines. Because carpet tiles appear seamless, like one large continuous floor, worn areas would stick out like a coffee stain on a white shirt.
The solution: Learning from nature.
Based on biomimicry - the study and imitation of nature’s best ideas to solve human problems – Staticworx ShadowFX static-dissipative (SD) carpet tiles mimic the organic design of nature. Tiles vary in patterns and colors within one style and colorway - all but eliminating the ability to observe pile crush or other forms of wear between tiles.
Because there’s no need to worry about matching dye lots, you need less attic stock and selective replacement is more effective. Replacement tiles are almost indistinguishable from older - original - tiles in the same installation.
Non-directional Installation for Less Installation Waste
ShadowFX SDC Patterns and Cubic Collections offer the added benefit of non-directional installation, meaning that tiles can be laid in any order or orientation. With no set pattern to maintain and no need to align tiles in a certain direction, there is significantly less installation waste. In fact, the average ShadowFX non-directional installation produces only 1.5% waste versus an average of 14% for other carpet styles. That means more of your floorcovering investment is on your floor, not in a dumpster.
And the best part, ShadowFX carpet tiles can be installed without glue, as a floating floor over any hard surface.
In sophisticated tones with threads of complementary colors in varying widths, our Parks Series carpet tile puts an earthy twist on classic linear design. A low-profile face uses less material for a tailored, upscale aesthetic.
Simplicity Meets Style
Treez, our latest ShadowFX carpet tile collection, marries timeless style with the simplicity in nature. Tufted, textured loop construction adds dimension, creating a look as natural and stately as the bark on a tree. As appealing and comfortable in an uptown financial services space or high-tech lobby as in a workhorse application such as a data center or manufacturing facility.
ShadowFX SDC Chenille Warp Carpet is a tufted patterned level tip-sheared pile carpet tile, with SD backing. The pile material is made from recycled solution-dyed nylon. The fundamental aesthetic of Chenille is stripes which have been interpreted in a bold and textural way without relying on heavy face weight. Shadow FX Chenille Warp is available in four colorways. The tiles can be installed in a variety of ways including quarter-turn, ashlar, brick fashion and parquet, with the potential to provide an unconventional appearance.
Linear precision, softened by texture and offset shapes.
As its name suggests, Furrows II has a resilient patterned loop pile carpet, reflecting the linear regularity of ploughed fields. Its textured, structured loop pile creates the three-dimensional impression of an aerial view of a cultivated landscape.
Designed for heavy contract performance, ShadowFX Furrows II maintains its distinctive appearance even in high-traffic areas. Pile yarn and backing contain pre-consumer recycled material, minimizing environmental impact.
