End
- An individual fiber making up a yarn to be tufted into carpet.
- An individual pile yarn in a tufted carpet or a roll.
- An end or short length of carpet or remnant.
ESD Carpet
Electrostatic Discharge Carpet is specially constructed to meet the requirements for an ESD-controlled environment, which is generally restricted to applications involving electronic-component assembly or where electronic components and/or circuit boards are routinely handled. In an ESD-controlled environment, the static generated by walking on the floor must typically be less than 0.2 kV (200 volts). An ESD-controlled environment requires the use of special ESD shoes, and generally includes the use of electrically-grounding wrist straps, special grounded work surfaces, ESD smocks over clothing, and control of humidity within the range of 40-60% RH. ESD carpet incorporates electrically-conductive elements which connect to a conductive backing, which is glued to the floor with special conductive adhesive, then carefully connected to the building ground at specified intervals. The use of electronic equipment, computers, digital phones, etc., in a typical commercial space does not require the use of ESD carpet, as long as permanent static control is built into the commercial carpet product.
Extra Heavy Traffic
More than 2,000 traffics per day. Could also include some directional, nondirectional, pivoting and rolling traffic, as well as tracked-in dirt. See "Foot traffic units.(See "Foot traffic units.")
Extrusion
Refers to the second stage of nylon production. The process of forcing molten material through a spinnerette (similar to a showerhead). Once exposed to air cooling, the fiber strands harden. It is at the extrusion stage that many of the fiber engineering improvements take place: cross section design, shape, size and
