Tab

The starting point of a weave. This is seen in diagrams A and B which are said to be plain weaves ,on opposite tab'. Tab is probably derived from 'tabby', especially when used in relation to plain weave.
note: When two or more weaves are combined to form a stripe, cheek, or figured design, a better fit of the weaves and a neater edge to the figure is obtained by ensuring that the weaves used are 'on the tab' or on the correct footing relative to each other. (See also mock.)

Tabaret

A finely woven, yarn-dyed furnishing fabric that has alternate warp stripes of satin and plain weave.

Tabby

The simplest of all weave interfacings in which the odd warp threads operate over one and under one weft thread throughout the fabric with the even warp threads reversing this order to under one, over one, throughout.
note 1.. A plain weave does not necessarily result in a plain surface effect or design in the fabric, e.g., variation of the yarn linear densities warp to weft or throughout the warp and/or weft and variation of the thread spacing warp to weft can produce rib effects (see taffeta, poult, faille and grosgrain), while colour patterning of the warp and/or weft results in colour-and-weave effects.
note 2: The area containing the two solidly filled squares in the square paper design indicates one weave repeat, i.e., 2 ends x 2 picks.

Tablet weaving

A method of producing woven plain or patterned narrow fabrics. The warp shed is controlled by tablets made of thin, stiff material, e.g., cardboard, plastic, bone etc. Tablets are usually about 5cm to 10cm square, although other shapes, e.g., triangles, hexagons, etc., are also employed. Each tablet has a hole at each corner through which the warp yarns are threaded. Rotating the tablets controls the rise and fall of the warp yarns. If the tablets are continually turned in one direction, the yarns threaded through the same tablet twist around each other giving a warp twisted structure, but by frequently reversing the tuming direction, the twist can be obviated and normal warp weft interlace in ends are produced. This, combined with the turning of tablets individually, not altogether as a pack, gives at large range of structure and design possibilities. In all these cases, the result is a warp-face fabric, the weft normally being visible only at the selvedge. Rotation of the tablets, weft insertions and beat-up are normally hand operations.

Tabourette

A finely woven, yarn-dyed furnishing fabric that has alternate warp stripes of satin and plain weave.

Tackiness

The property of being sticky or adhesive.

Tacking

The sewing together. of the two selvedges of a fabric to form a tube in order to prevent selvedge curling, to encourage ballooning, and thereby reduce rope marking (see rope marks) in the fabric face during wet processing

Tackspun fabric

A material made from a polymer film with a backing substrate. The film is melted by a roller to which it adheres. As the film and roller separate a fibrous pile is formed.

Tactic Polymer

A polymer whose molecular structure exhibits regularity or symmetry of non-backbone side groups rather than random ordering. (Also see ATACTIC POLYMER ISOTACTIC POLYMER and SYNDIOTACTIC POLYMER.)

Taffeta

A plain-weave, closely woven, smooth and crisp fabric with a faint weft-way rib, produced from filament yarns. The rib effect is produced by making the warp end density greater than the pick density. The warp and weft yarns are of similar linear density.
note 1: Taffeta belongs to a group of fabrics that have ribs in the weft direction. Examples of this group, arranged in ascending order of prominence of the rib are: taffeta, poult, faille, and grosgrain.
note 2: The term 'wool taffeta' is often applied to a plain-weave, light-weight fabric produced front worsted yarns.

Taffeta ribbon

A ribbon of continuous-filament yarn in plain weave, with a relatively high warp density and very fine, almost imperceptible rib, generally with a selvedge of contrasting weave tail A length of yarn wound on to a cheese or cone at the comi-nencei-nciit of winding that protrudes from the main build-up of yarn and can later be attached to the free end of yarn of a second package during magazine creating.

Tailing

A dyeing fault consisting of a gradual change in colour along a length of material to which colorant has been applied by padding or other continuous techniques.

Tak Dyeing

See KUSTERS DYEING RANGE.

Take-Up (Twist)

The change in length of a filament yarn or cord caused by twisting expressed as a percentage of the original (untwisted) length.
