Best Carpet Yarn 3.......
Solution Dyed Carpet Yarn. Simply The Best....
We finish up our discussion on best carpet yarns this week with this blog on solution dyed nylon. The solution dying process is mainly used in commercial grade carpet. You don't see this process used very often in the manufacture of residential carpet but one of the big three carpet mills, Beaulieu, has a new line of carpet using this dying process.
Simply put, solution dying is the process of injecting the dye into the carpet yarn while it is still in liquid (solution) form. When the yarn is extruded the color (dye) is all the way through the yarn. Most carpets are made with greige goods and then dyed to a specific color. In this process the carpet is made with greyish/white colored yarn and then run through a dyer where the yarn is dyed. If you were to cut a carpet yarn in half that is dyed in the conventional method, the inside of the yarn would still be the greyish/white color. If you were to cut a solution dyed nylon carpet yarn in half, you would see that the yarn is colored completely through. Inside and out.
Because of the way solution dyed yarn is dyed, it is very stain resistant, extremely fade resistant and still wears like a nylon yarn (because it is a nylon yarn). So you get all of the benefits of nylon yarn (wear resistance, resiliency and softness) along with the fantastic stain resistance that you would normally see in olefin yarns or polyester carpet yarns.
Some of the best warranties in the business are attached to this style of carpet (and I mean actual warranties, unlike some of the warranties that mills put on their carpets that have so many restrictions and limits that they will almost never pay off on any of their warranties!!).
You can even clean some of the toughest stains using a mixture of half water and half bleach! Try that with any other type of carpet yarn and see what happens........large whiteish blotches will form on your carpet if you were to try this cleaning solution with just about any other type of carpet.
So in our humble opinion, solution dyed nylon is the best carpet yarn to use for residential carpet. Really no need to say anything else....

Best Carpet Yarn 2.......
So now that we've discussed the value of wear and resilience in carpet yarn, this week we will touch on stain resistance.
Stain resistance has taken on added importance these days as family's lifestyles are getting busier and more hectic. There was a time that most family's wouldn't let you eat in the family room much less the living room. Do you remember as a kid how if you tried to take some food into the family room to watch TV while you ate, your mother would let you know about it. Food and drink just weren't allowed in carpeted rooms. Because of this, wear and resiliency were more important than stain resistance.
These days, everybody eats in the family room. They eat in the living room. And in our bedrooms. And the basement (which are mostly carpeted these days). We pretty much eat everywhere in the house. Because of this (and the resultant spillage. Yikes) carpet has to be stain resistant. What good is carpet that will wear forever if it stains up like crazy.
Scotchgard was one of the first stain protections developed. It was a topical treatment that provided a barrier between dirt, stains etc and the carpet yarn. This barrier stopped stains from penetrating into the carpet as long as you cleaned up the spill relatively fast. Dirt also cleaned off of the carpet. One of the drawbacks to this topical treatment was that after a couple of cleanings, most of the topical treatment was gone leaving the carpet yarn exposed to future spills.
Along came the built in stain protection. Stainmaster, Anso, Weardated and Scotchgard Stain Release were the top brands in built in stain protection applied to mostly nylon carpet yarns. Basically how this worked was that the yarns were treated with a fluorocarbon system. Most carpet yarns when they are extruded will have very fine pores. These pores will absorb spills and are hard to clean out. This is the idea behind hot steam extraction. Hot steam penetrates the yarn and cleans as the steam is extracted out of the yarn. The built in stain protection basically filled these tiny pores thereby creating essentially a solid yarn. This solid yarn won't absorb spills. The stain will stay on the surface of the yarn and is easily cleaned off with a good carpet cleaning solution. Most nylon yarns are treated for stain resistance in this way.
Polyester on the other hand is inherently stain resistant. PET polyester is made with recycled pop bottles. A form of plastic. This yarn is extremely hard to stain. Because of polyesters superior stain resistant properties, this yarn is starting to take market share away from nylon (the fact that polyester costs less than nylon doesn't hurt either).
Olefin yarn (used mainly in Berbers and commercial grade carpet) is also extremely stain resistant because of it's hydrophobic properties (it doesn't absorb water so it won't absorb stains). This is why olefin carpet is solution dyed (the yarns are dyed while they are still in liquid form so the color goes throughout the yarn). Not only does olefin not absorb water or stains but it also doesn't absorb the dye very well during the dying process. So the carpet mills will dye the carpet before extruding the yarn. More on solution dying later (hint: solution dyed nylon, probably the best yarn period as it combines wear ability, resilience and stain resistance in one yarn......)
Wool, since it's a natural yarn and hence porous, will absorb stains and is probably the worst yarn for stain resistance.
Rankings of carpet yarn for stain resistance
- Solution dyed nylon
The top three are considered extremely stain resistant and will suffice for most carpet installations where stain resistance is the top priority. Next week more on solution dyed nylon.........the best carpet yarn period (in our humble opinion).
