Needle board<br />
In the needlepunched technology, the needle board is the part of the needle loom to which the<br />
barbed needles are anchored. The needle board is fastened to the needle beam.<br />
Needlepunched or Needlepunching<br />
Mechanically binding a web to form a fabric by penetrating the web with an array of barbed<br />
needles that carry tufts of the web’s own fibers in a vertical direction through the web.<br />
Neps<br />
Small knots of tangled fibers that were not separated before forming the web.<br />
Nip<br />
The line of close contact between two calender rolls between which a fabric or web passes.<br />
Nonwoven fabric<br />
A fabric made directly from a web of fiber, without the yarn preparation necessary for<br />
weaving and knitting. In a nonwoven, the assembly of textile fibers is held together 1) by<br />
mechanical interlocking in a random web or mat; 2) by fusing of the fibers, as in the case of<br />
thermoplastic fibers; or 3) by bonding with a cementing medium such as starch, casein,<br />
rubber latex, a cellulose derivative or synthetic resin. Initially, the fibers may be oriented in<br />
one direction or may be deposited in a random manner. This web or sheet is then bonded<br />
together by one of the methods described above. Fiber lengths can range from 0.25 inch to 6<br />
inches for crimped fibers up to continuous filament in spunbonded fabrics.<br />
Nozzle<br />
A term occasionally used in reference to the spinneret of a spunbond production line or fiber<br />
spinning system.<br />
