The most common type of woven loop tape is napped, or brushed, loop made from 100% nylon. This tape is considered a general-purpose fastener and is used for a wide variety of applications.

Napped loop consists of woven fibers that are randomly disoriented, which allow for hooks of many types and good penetration, provides high peel and shear strengths, as well as excellent cycle life.

Unnapped woven loop consists of a series of unbroken loops, which allow the loop to last longer over time and is used in applications which don’t require a high peel strength. This loop can provide a cycle life of over 20,000 and has a high quality “clean” appearance, as well as quick drying properties.

Both napped or unnapped loops come in a variety of widths, colors, and put-ups. They can also be made into die cut shapes, fabricated straps, and with adhesive tape.
