REASON FOR COMMISSION The carpet reportedly had a problem with cornrowing.
THE REPORT Site Conditions and Geographical Information The carpet was installed in the claimant's free standing single story house, located in a residential neighborhood in the Hollywood Hills. The house was well maintained and was owner occupied at the time of the inspection.
BACKGROUND INFORMATION MADE TO THE INSPECTOR A problem with a noticeable line was noticed the morning after the carpet was installed. Later other lines were noticed throughout the installation. The visibility of the lines had not changed since they were first noticed and no corrections had been attempted.
DESCRIPTION OF PROBLEM AREA BY THIS INSPECTOR A line running in the direction of manufacturing was noticed upon entering the hall. This line was most noticeable when viewed directly over head and was confined to only one 'high' stitch-row of the pile. This row appeared to be fatter or had less twist than the adjacent rows. In the family-room a widthwise line was noticed 20.5 inches from the wall. In this line loops in the 'low row' were slightly pulled. In this room was another line running in the direction of manufacturing, similar to the one in the hallway. In the back bedroom, another fat row running in the direction of manufacturing was noted.
ON-LOCATION FIELD TESTING An inspection lamp was used for closer evaluation and to create shadows, but a shadow could not be made from the line indicating that it was lower than the surrounding pile. A Pile Direction Test was done using a piece of paper and a pencil, but the pile direction was not discernible with this test.
THE ISSUE The question that I have been asked to address is what has caused the carpet to develop lines.
GUIDELINES FOR EVALUATING THE ISSUE
INDUSTRY STANDARDS & DEFINITIONS The rules, standards, and or guidelines for each of these processes are available upon request.
THE INSPECTOR'S ANALYSIS Roll crushing and installation errors generally create a wider line than this one and normally do not have pulled loops. Since all but one of these lines follows the direction of manufacturing and individual stitch row, they are inherent in manufacturing. Since they do no make shadows and the yarn appears to be fatter, the problem is likely from improper twist or some variation of that problem. The width wise line was likely some type of momentary variation in the tension.
