Excerpt from a technical guide I worte on this fiber -
CARPET CLEANING
Triexta
INTRODUCTION
You may be getting asked to clean fibers you have not encountered before. Consumers may be identifying their carpet as Triexta, SmartStrand, Sorona or asking if you can clean fiber made from corn.
Our industry saw its first official new fiber for many years in March 2009 when the Federal Trade Commission (FTC) recognized polytrimethylene terephthalate (PTT) as a new class of fiber. It had previously been consider a type of polyester.
PTT was initially developed by DuPont back in 1941. In 1999 Shell started marketing PTT under the trade name Corterra. Use of the fiber was limited and mostly in clothing fabrics not carpet.
Shaw industries began marketing Corterra as a carpet fiber in 2001. Mohawk began making PTT under the name Smartstrand beginning in 2004.
A version of PTT including 37% of a DuPont resin that originates from corn was brought to the market by Mohawk. It is called Smartstrand with DuPont Sorona.
This could be spun into fibers and tufted into carpet using the same equipment as was being used for nylon fiber carpets. With the ability to be processed on existing equipment and the green appeal of using corn, a renewable resource, PTT has now holds a small but growing share of the carpet fiber market.
So, how should this fiber be cleaned?
PROCEDURE
It is anticipated that Triexta fibers will resist staining with acid food dyes and be somewhat resistant to disperse dyes. (the yellow of turmeric in mustard is an example of a disperse dye.) PTT does have an affinity for oil and grease, but should respond well to cleaning if it is done on a regular basis, at least annual for typical family use.
? STEP 1 DRY SOIL REMOVAL
Begin by vacuuming the carpet to remove dry soil. It is easier to remove many soils before they are mixed with cleaning solutions.
? STEP 2: SPOTTING
Determine if any spots will need extra attention prior to cleaning and go to work with your Bridgepoint Spotting Kit. Most spotting can be done after cleaning.
? STEP 3: PRESPRAY
Apply Traffic Slam to the carpet using a quality sprayer. When fibers are heavily soiled with oil or grease be sure to add 1 or 2 ounces of Citrus Solv per gallon of ready to use prespray. Traffic Slam has a charged hydrotope that helps overcome Vander Waals forces between this fiber and very samll particles.
Agitate the carpet with a Grandi Groomer. This will work the solution into the carpet and the physical agitation will loosen the soil.
? STEP 4: EXTRACT
Use End ZONE or Power Point in the chemical injection system of the truckmount or in the solution tank of your portable machine.
? STEP 5: NEUTRALIZE (OPTIONAL)
Spray the carpet with a dilute solution of Fab-Set. This will neutralize any alkaline residue. For lightly soiled carpet, some technicians use Fab-Set as their rinse agent. This cuts out the neutralization step but you will sacrifice some cleaning power.
? STEP 6: PROTECT
For fibers other than olefin, apply Maxim Advanced Carpet Protector to the clean carpet.
? STEP 7: PILE SETTING
Groom the carpet using Grandi-Brush or Grandi-Groom. This makes sure the protector is evenly distributed while also removing wand marks and footprints. This creates a good visual impression but
even more importantly it aids drying by straightening and separating the fibers.
? STEP 8: DRYING
Be sure that ventilation is at optimum levels by opening windows, turning on ceiling fans, turning on the heat or air conditioner, etc. If the customer has an evaporative cooler you may turn on the fan portion but don’t turn on the water pump as this will slow drying by adding humidity. Moving the
Air Mover from room to room will speed drying and enhance customer satisfaction.
? STEP 9: FINISHING TOUCH
Leave your customer a bottle of Home Pro spotter so they can remove spots and spills while they are fresh. They will have your company name and phone number handy to call you for their next cleaning.
