Bicomponent yarn

A yarn having two different continuous filament components

Bi-component fibres

Fibres spun from two different polymers. The most common types are made from polymers which have different melting points and are used for thermal bonding. Another variant is produced from polymers which have differing solubilities.

In this case one polymer may later be dissolved out to leave ultra-fine filaments. An example is the production of suede-like fabrics. This process is also used to create crimping, in order to provide bulk or stretch.

Bias

The direction diagonally across a piece of fabric at 45º to the warp and weft. Bicomponent fabric: A fabric with two layers.

Bedford cord

A fabric constructed in such a way as to show rounded cords in the warp direction with pronounced sunken lines between them.

Batt

Single or multiple sheets of fibre used in the production of nonwoven fabric.

Batik

A traditional dyeing process in which portions of cloth are coated with wax and therefore resist the dye, enabling distinctive patterns to be created. Batik fabrics are characterised by a streaky or mottled appearance.

Bast fibre

Fibre obtained from the stems of certain types of plant.

Basket weave

A textile weave consisting of double threads interlaced to produce a checkered pattern similar to that of a woven basket.

Bandana

Handkerchief designs in simple colour and white stylised patterns, including spots and paisley.

Ballotini

Small glass beads which are normally used in reflective paints but which can also be incorporated into fabrics.
