According to the Carpet and Rug Institute and carpet manufacturers such as Shaw Industries, wrinkles, ripples or waves can appear in carpet after installation for a variety of reasons:
The remedy for wrinkled carpeting (assuming the backing is not delaminated) is to re-stretch it using proper methods and equipment. In those areas to be re-stretched, it will be necessary to remove all furniture and objects, so that they do not interfere with the free movement of the carpet. Re-stretching clean carpet in good condition will not damage it or shorten its life, and with normal usage and maintenance, wrinkles should not re-occur.
It is normal for new carpet to shed or fluff. The first few times you vacuum, do not be shocked if the bag is full of loose fibers. This is attributed to several factors, including the cutting of the carpet itself. Some carpets are made from short fibers and stapled to the backing. In this process some fibers will be missed and not anchored down. Also, a final process on most carpets is sheering the tops of the fibers, even though an industrial vacuum follows the process, there are still fibers that are missed. These are only some things that attribute to shedding.
The amount of loose fibers, traffic level, type of vacuum, and vacuuming procedure all attribute to how long the carpet will shed. Generally the shedding will substantially slow down in the first few months and almost stop completely in 6 months.
After the carpet is professionally cleaned it may begin to shed again, but only for a short time. The agitation of the cleaning machine may loosen fibers that are actually held in place by oils and dirt in the carpeting. Loosening fibers will not affect the durability of your carpet. The more thorough and frequent the carpet is vacuumed, the less shedding will affect you and your home.
As time goes by, some owners notice that their Berber carpet begins to look frayed or fuzzy. This is caused not by the quality of the carpet, but by the vacuum cleaner’s beater brush.
Fraying and fuzziness can be prevented by:
On a final note, Berber carpets usually have more pronounced seam peaking than pile-cut carpets due to their thicker backings.
This is a perplexing problem to homeowners involving dust accumulation on carpet fibers in areas with a concentrated airflow such as air ducts and where the edge of carpet meets the wall baseboards. This condition is not dependent on the type of carpet that was selected. It also does not indicate a manufacturer’s defect.
