Fettling

1. The maintenance of textile machines.
2. The process of cleaning fibres and other material from the clothing of a carding machine. This was necessary with flexible card clothing, which tended to readily accumulate material, but is less common with metallic card clothing.

FIBC

A fabric container used for transporting and storing quantities (approximately 1 to 5 tonnes) of bulk commodities, such as powders and granular materials.
Note: The containers are characterised by webbing or fabric lifting loops that enable them to be handled mechanically by crane or fork-lift. They may be made from coated or uncoated woven fabric and may be fitted with an inner liner made of polymer film and filling and emptying tubes. Uncoated fabrics are normally constructed from tape yarns woven at high sett to give a fabric of low permeability. FIBCs may be designed to be single trip or multiple trip.

Fiber

Textile raw material, generally characterised by flexibility, fineness and high ratio of length to thickness.

Fiber Architecture

The spatial arrangement of fibers in the preform. Each architecture has a definite repeating unit.

Fiber Distribution

In a web the orientation (random or parallel) of fibers and the uniformity of their arrangement.

Fiber Migration

See MIGRATION 2

Fiber Number

The linear density of a fiber expressed in units such as denier or tex. (Also see FINENESS.)

Fiber Placement

In general refers to how the piles are laid into their orientation i.e. by hand by a textile process by a tape layer or by a filament winder. Tolerances and angles are specified. Microprocessor-controlled placement that gives precise control of each axis of motion permits more intricate winding patterns than are possible with conventional winding and is used to make composites that are more complex that usual filament-wound structures.

Fiberfill

Manufactured fibers that have been specially engineered for use as filling material for pillows mattress pads comforters sleeping bags quilted outerwear etc. Polyester fibers are widely used. © 2001 Celanese Acetate LLC

Fibre

Textile raw material, generally characterised by flexibility, fineness and high ratio of length to thickness.

Fibre migration

The change in of a fibre or filament "n the axis of a yam during production

Fibre or man-made fibre (see fibre, manufactured).

fibre, manufactured; fibre, man-madeA fibre that does not occur in nature, although the material of which it is composed may occur naturally. (See also fibre, natural.)
Note: The raw materials for the manufacture of fibres may be derived from:
(i) naturally occurring, non-fibrous materials, for example, metal fibres from a variety of metals and their ores, glass fibre from silica and other minerals;
(ii) natural polymers, for example, rubber fibre from latex, viscose from wood cellulose, azlon from natural proteins (see fibre, regenerated);
(iii) synthesised polymers such as the polyamides and polyesters (see fibre, synthetic);
(iv) other manufactured fibres which then undergo further significant physical or chemical modification, for example, carbon fibre from acrylic or pitch fibres.(sub category of fibre)

Fibre quality index

A numerical value indicating the process ability of cotton calculated from its fineness,length and tenacity values.

Fibre ultimate

That, unit cell beyond which subdivision is not possible with out loss of a fibre's identity.

Fibre, chemical

A literal translation of various non-English terms having the same meaning as manufactured(sub category of fibre)
