Appearance Retention is related to three subtopics:

  1. Color Loss and/or fading
  2. Rapid Soiling
  3. Texture Changes

If the problem is color loss, then go to the Color Loss section. If the loss was created by environmental conditions, then you need to run one of the laboratory tests to see if the carpet has a manufacturing defect.

If the problem is Rapid soiling, there could be spin finish and/or coolant left on the faceyarn by manufacturing. To see if there is a possible manufacturing defect, have an independent lab run either ASTM D 2257 or AATCC 20A extractable matter tests. ASTM D 2257 is often done with ETHYL ALCOHOL and will not remove LATEX. AATCC 20A is done with CHLOROFORM and will remove all spin finish and/or coolant plus any latex. Both can be done to separate the amount of spin finish and/or coolant from latex. The results of either test are given as a percentage compared to the amount of faceyarn. Anything under 0.5% is great. Between 0.5 to 0.8 is generally not a problem either. From 0.8 to 1.5 percent will likely cause rapid soiling; although, it will likely not be considered a defect worthy of replacement. However, some mill responsibility may be required to clean and/or move the excessive spin finish and/or coolant. PROCHEM makes a detergent call FORMULA O, the should be effective on Olefin. Between 1.5 percent & 2.0 percent there are two opinions as to whether this is a defect worthy of replacement. Doctor Eric Brown of the CLEANING RESEARCH INTERNATIONAL in his book called DIAGNOSTIC TECHNIQUES FOR THE INVESTIGATION OF CARPET COMPLAINTS says that 1.5 percent is the standard for Wool with respect to Lanolin. The GSA standard on this site call CARPET AND RUGS, WOOL, NYLON, ACRYLIC, MODACRYLIC POLYESTER, POLYPROPYLENE says 2.0 percent. There is an old report on this site where the results were in between these two standards. Click here to see.

Texture Changes are related to issues like crushing and loss of twist. Lost of Twist has no laboratory test specifically for it along; however, ASTM 5151 or ASTM D-6119 will evaluate the overall change in appearance which will achieve the same result as a twist/lost test. CRI will give additional information on this if you click here.
