Acid dyeable nylon:
Nylon polymer that has been modified chemically to make the fibre receive
acid dyes. Acid dyeable yarns are available in different dye levels (light,
medium and deep).
Aesthetics:
Properties perceived by touch and sight, such as the hand, colour, luster
and texture of carpet.
Affinity:
The tendency for two elements or substances to combine chemically. An
example is the affinity of acid dyes for nylon fibre.
Air-entangling (also known as intermingling, commingling or heathered):
A method of producing yarn by combining two or more BCF fibres together.
Fibres are "locked" together via air jets at regular or irregular
intervals. The process is used to get special effect yarn (i.e., mixing
dye variants to get heather effects upon subsequent dying or combining
different colors of solution dyed fibre). Various air-entangling processes
exist making it possible to produce a wide range or aesthetics in finished
yarns, from highly blended, near solid looks to yarns where individual
colors are accented and colour separation mimics that of plied yarns.
Amine end groups:
The terminating (-NH2) group of a nylon polymer chain. Amine end groups
provide dye sites for nylon (polyamide) fibres.
Antron®Legacy™** nylon

applications with all the qualities of Antron® Type 6,6 nylon fibre. Antron
Lumena® gives carpets unsurpassed stain cleanability. Most stains can be
removed without the use of harsh cleaning agents. (See "
Antron® Nylon.")
*Formerly known as Antron® Excel SC.
Antron® Nylon
The best-known, most-purchased brand of commercial carpet fibre. Antron®
nylon combines a superior Type 6,6 polymer substrate, exclusive INVISTA fibre
engineering, Teflon® advanced soil resistance technology, and INVISTA
performance testing and construction standards, resulting in carpet fibres
that perform well in the most demanding commercial environments.
Autoclave:
(1) An oven-like apparatus for use in yarn heatsetting operations. Under
pressure in a superheated steam atmosphere, yarn is given a "memory"
of its twist. Autoclave heatsetting is a batch, not a continuous, method.
(2) An apparatus for making polymer under heat and pressure.
Axminster:
A weaving method that originated in the 18th century in Axminster, England.
In this method, individual pile tufts are inserted from spools of colored
yarns, making possible an almost endless variety of colors and geometric
or floral patterns.
