| knee kicker | A carpet installation tool consisting of a pinned plate connected to a short section of metal tubing. The end opposite to the plate has a padded cushion which the installer strikes with his knee to stretch carpet which is gripped by the pinned plate. Knee kickers should be used only in areas which are so small that power stretchers cannot be used. In general, adequate stretching of commercial carpet installations cannot be achieved with knee kickers. |
| knitting | A method of fabricating a carpet in one operation, as in weaving. Surface and backing yarns are looped together with a stitching yarn on machines with three sets of needles. |
| kraftcord | A tightly twisted yarn made from plant fiber, used as a backing yarn. |
| kusters dyeing | Continuous dyeing using the kusters dye applicator and range. This is described in more detail in the text under continuous dyeing. |
A number of carpet problems may not be carpet defects. They can occur as a result of environmental conditions or carpet cleaning problems.
