Rug fringe: why it frays, greys and falls out, and what to do

What fringe is

On a hand‑knotted rug, the fringe is the warp threads, the rug's skeleton, continuing past the last row of knots. Between the fringe and the pile is the end finish, a band of weaving or overcasting that holds the last knots. When the end finish wears through, the rug loses a row of knots every time it is vacuumed, and the border starts to disappear. On tufted and machine‑made rugs the fringe is a sewn‑on strip and is decoration.

What damages it

• Vacuum beater bars and robot vacuums, which twist and chew it. See how to vacuum a Persian rug.
• Bleach, which some cleaners use to whiten cotton fringe; it rots the cotton and the fringe crumbles within a year or two.
• Doorways and chair legs, which wear the ends and sides.
• Damp, which rots cotton ends on rugs stored on basement floors.

How it is cleaned

At the Farmingdale plant fringes are washed by hand during the wash, combed straight, and whitened with a wool‑ and cotton‑safe brightener, never bleach. Grey, matted fringe on a Pakistani Bokhara (the longest fringes in the business) comes back white and straight.

End stopping

If the end finish has worn through, the last knots are secured with a hand‑worked overcast or a rebuilt kilim end that matches the original. This is the single most valuable small repair on a rug, priced by the linear foot, and it is done before the wash so nothing unravels in the water.

Replacement

Where the fringe is gone entirely, the original warps can be rebuilt on a fine rug, or a matched fringe sewn on where that is the sensible choice. We recommend which at inspection.
