Snagged Carpet Backing Problems

Carpet-Backing Layers

• The tufts of the top of the carpet are inserted into the primary backing. Primary backing can be made of various materials, such as cotton or jute, but is often made of polypropylene. The secondary backing layer is the material applied underneath the primary layer to secure the carpet tufts. Secondary backing can be made of various materials, such as jute or polyethylene, and some backings are cushioned or have a special purpose, such as moisture resistance.

Delamination

• Delamination is a term that refers to a separation of the primary and secondary layers. This causes the carpet to wrinkle or lift up in spots, causing the carpet to snag. Excessive snagging can cause fraying by the walls and room openings, such as doorways. The loops on a loop pile carpet -- carpet with woven loops on the surface -- can pull right up. A cut pile carpet will show fraying and loose threads at the seams.

Delamination Causes

• Backing separation can be caused by a wide range of events or conditions. Production errors, the use of overly thick carpet padding or the excessive use of carpet stain cleaners can result in delamination. Some spills, such as oil-based liquids or urine, can cause separation of layers as well as the frequent moving of heavy items across the carpet. Any areas of the carpet that are left wet for a long time can experience delamination.

Prevention and Remedies

• Any spills on the carpet should be cleaned up immediately with the least amount of added moisture possible; wet spots should be blotted dry. In cases in which a manufacturing defect is causing the problem -- usually evidenced by the layers easily peeling apart with little force -- a carpet inspector can test a section to present to the manufacturer. If the carpet is still under warranty, the owner can contact the manufacturer for help. If the delamination was caused by owner actions, such as frequent spills, the carpet may need to be replaced.
