Ginning

A process that removes cotton fibres (lint) from the seed.

Glac'e binding

A woven narrow fabric made from polished cotton warp and weft yarns. It is used principally in the men's tailoring trade, and usually in 3/1 twill weave, and 12.5mm wide. The stiffness imparted during weaving is sometimes enhanced by subsequent finishing.( Sub Category of binding)

Glacé

A lustrous glossy effect imparted to fabrics by finishing.

Glass (fibre) (generic name)

Fibre, in textile form. obtained by drawing molten glass. (See also Classification Table, p.40 I.) in practice, glass filament or fibre is also produced by Note 1: The above is the ISO definition;extrusion or other spinning processes.
Note 2: Glass is described in ASTM C 162-89 as: 'An inorganic product of fusion which has cooled to a rigid condition without crystallizing.
Note 3: Glass fibres used in textiles consist of vitreous silicates or borosilicates.

Glass Fiber

A manufactured fiber in which the fiber-forming substance is glass (FTC definition). In the continuous filament process glass marbles are melted in an electric furnace and the liquid flows in fine streams through small orifices at the bottom of the melting chamber. The resultant filaments are caught and drawn by a high-speed drawwinding mechanism. In the staple fiber process the streams of molten glass are attenuated into fibers by jets of high-pressure steam or air. These fibers are gathered on a revolving drum and them wound on tubes to form staple fiber sliver or bands that can be drafted twisted and plied.

Glass Transition Temperature

See SECOND-ORDER TRANSITION TEMPERATURE.

Glass-rubber transition temperature

Temperature region over which there is a reversible physical change from a viscous or rubbery state to a brittle glassy state.

Glaze

To produce a smooth, glossy, plane surface on a fabric by heat, heavy pressure, or friction by friction calendering, or as a fault.
Note: Glazing may be produced intentionally,

Glazing

1. A finishing process that produces a smooth highly polished or lustrous surface on a fabric such as chintz. The fabric is treated with starch glue paraffin or shellac then friction calendered. Synthetic resins are used for a more permanent finish. 2. A shiny fabric appearance produced unintentionally e.g. by pressing at excessive temperature.

Global Radiation

The wavelength distribution of sunlight under a given environment (e.g. under windowpane glass).

Go-through machine

A Leavers type of machine, in which the catch bars impart motion to the carriages.

Goat fibre (hair)

Fibre from the common goat (Genus Capira).

Godet

1. (Fibre manufacture) A driven roller, which may be heated, around which yarn is passed in order to regulate its speed during the extrusion and further processing of certain manufactured fibres.
Note: Godets usually have a single flange and are mounted on an axle from the flange side. They may be constructed with serrations broadly parallel to the axis, and may be tapered or stepped.
2. (Clothing) Material cut in a wedge-shaped segment of a circle and let into a seam or slash to give decorative extra fullness to a hem.

Going-part

Also known in the U.K. as lay, lathe, batten, going-part, fly-beam.
