What is "Bicomponent Fibre" - Definition & Explanation

A fibre formed by the conjunction at a spinning jet, of two fibre-forming polymers of different properties.

NOTE:

a) The two components may be caused to merge approximately side by side (bilaterally), concentrically or as fibrils of one component in a matrix of the other. An example is the production of crimped fibre, e.g. a combination of polymers of different contractive properties.

b) Although formed by a natural process, wool and related animal fibres may exhibit a comparable dual structure of the cortical cells.

A Man-made Fibre Having Two Distinct Polymer Components. Both Components Are Themselves Usually Fibre Forming. Wool And Some Other Animal Fibres Are Sometimes Considered To Be Bicomponent Since They Possess A Side-by-side Configuration Of The Ortho- And Para-cortex Which Results In Crimp In The Fibre.
A manufactured fiber formed by spinning and joining together two different polymers such as nylon and polyester simultaneously from one spinneret. Sometimes called conjugate fiber.
