Laminate<br />
A layered material containing two or more sheets bonded together with an adhesive, foam or<br />
thermoplastic resin.<br />
Laminate nonwoven<br />
A laminate of two or more layers of material in which the essential component is a nonwoven<br />
material.<br />
Lap<br />
A compressed sheet of fibers in a roll form, weighing about 50 pounds. The fibers are not<br />
bonded and are used to supply fibers to a card. Also called picker lap.<br />
Lap splitting<br />
A condition caused by a lap which will not unwind in carding in the same thickness as it was<br />
wound in picking. This splitting of the sheet of fiber can result in either a thicker or thinner<br />
sheet being fed into the card.<br />
Latex<br />
Either a naturally occurring milky appearing fluid from which rubber is made or a dispersion<br />
of a synthetic polymer in water. Typically used as binders.<br />
Latex Bonding<br />
See Resin Bonding.<br />
Lengthwise<br />
The machine direction in which the fabric is produced.<br />
Lickerin<br />
The name for a roller at the beginning of the fiber feed system of a card line. It is a high<br />
speed, saw-toothed wire roll that grabs the tufts of fibers fed into the system and deposits the<br />
partially opened fibers onto the main card cylinder.<br />
Lickerin loading<br />
A condition that can occur with the lickerin where fiber can become imbedded in the sawtoothed<br />
wire reducing the lickerin’s ability to grab fiber and transfer it to the main card.<br />
Limiting oxygen index<br />
Measure of flammability that determines the minimum concentration of oxygen in a gas mix<br />
that is required to sustain steady burning.<br />
