nap

Carpet or rug pile surface.

needle

(1) Jacquard loom - Has horizontal wires, rods, or plungers. The forward and backward movement is controlled by the pattern punch cards. One end is placed into a needle board and the ends extend slightly beyond the board surface. The other end projects into a leveling board, padder, needle box or spring box. The forward and backward movements position the lash cord knots to be picked up by the lash board, lifting board or comberboard, or the hooks to be picked by the griff or remain in the grate. (2) Axminster loom - Refers to metal rod used to insert a shot of filling yarn. (3) Knitting - The hooks that make the loops. (4) Tufting - The needle with an eye used to punch the pile yarn through the backing material.

needle bar

Tufting machine part that holds the needles and carries them up and down.

Did you know?

Carpet installation is the single biggest problem with new carpet purchases. Often, once the installation goes bad, the entire purchase begins to sour. Carpet installation should be carefully researched to make sure the carpet installer uses CRI 104 -CRI 105 Carpet Installation Standards. Failure to follow recommended installation procedures can allow for a shoddy installation. Always preserve about 1 square foot piece of the original uninstalled carpet. Some manufacturing defect analysis only can be performed on unused (untrafficked) carpet. Also, should the carpet fail (which is rare), it is helpful to evaluate a new piece versus a sample that has been trafficked. Attic stock (preserved carpet) also can be used to plug damaged areas or heavily stained or soiled areas.
