Anaphe

Fibres extruded by insect larvae other than Bombyx mori.
Note.. The most important of these larvae is tussah (tussore) (see tussah silk). Other types include: cri (Phylosamia ricini), muga (munga) (Antheraea assamensis), anaphe (Aiiaphe),kuriwata, and Gonometa postica

Angel lace, warp-knitted

A patterned warp-knitted fabric made with separating threads that are usually of secondary cellulose acetate subsequently dissolved out to leave narrow strips for trimming. It is generally produced on a tricot machine using atlas lapping movements to produce a scalloped edge.

Angle of lay

The angle at which strands lie in relation to the axis of the cordage.

Angle of lead

In ring spinning or ring twisting, the angle formed at the traveller between a package radius and the tangent to the package surface.

Angle of wind

The angle contained between a wrap of yarn on the surface of a package and the diametrical plane of the package.
Note: Other angles are: yarn-crossing angle, yarn-reversal angle (see diagram).

Angola

1. (Yarn) A yarn spun on the woollen system from a mixture of wool and cotton or other fibre.
2. (Fabric) A plain or twill fabric made from a cotton warp and an angola-yarn weft.

Angora

1. The hair of the Angora goat. The long fine fibers are so smooth and soft that they must be combined with other fibers in weaving. 2. The hair of the Angora rabbit. The fine lightweight hair is warm and it is often blended with wool to decrease price and to obtain novelty effects in weaving. By law the fiber must be described as Angora rabbit hair.

Angora fabric

A fabric woven from angora yarn.
Note: The use of this term to refer to fabric made of cotton warp and mohair weft is deprecated.

Angora fibre (hair)

Fibre from the angora rabbit (0ryctolagus cuniculus). (See also rabbit fibre (hair)) .
Note.. The hair of the angora goat is known as mohair.

Angora yarn

An extremely soft yarn made from the hair of an angora rabbit. The yarn is nominally of 1 00% angora fibre, although a small proportion of other fibres, e.g., up to 5%, is allowed in certain countries dependent on their fibre content labelling laws.

Anhydride

A compound formed by abstraction of water usually from an acid. Example: acetic anhydride which is used in converting cellulose to cellulose acetate.

Anidex (fibre) (U.S.A.)

A manufactured fibre made from a synthetic linear polymer that consists of at least 50% by mass of one or more esters of a monohydric alcohol and propenoic acid (acrylic acid). (See also Classification Table p.401.)

Anidex Fiber

A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 50% by weight of one or more esters of a monohydric alcohol and acrylic acid (CH2=CH-COOH) (FTC definition).

Animal Fibers

Fibers of animal origin such as wool alpaca camel hair and silk.

Anion

A negatively charged ion.
