A Review Study on Bicomponent (Bico) Fibre/ Filament

Abstract

Bi-component fibers are fibers that in a single fiber consist of two distinct raw material components. It is made by simultaneously spinning two compositions in each capillary of the spinneret. Core-sheath (C/S), side-by-side (S/S), segmented-pie (orange) and islands in-the-sea (I/S) are the most common types of bico fibers. The growing demand for non-woven fabrics is one of the growth drivers of the global bi-component fiber industry. In addition, bico fibers are also used in the manufacture of bulky goods, microfiber fabrics, advanced textiles, etc. Various types of commercial bico fibers as well as bico fiber fabrics are manufactured by many companies around the world. However, different aspects of bico fibers, their suitability in various fields of application, and some commercially available bico fibers are briefly reviewed in this paper.

Color matching of bicomponent (PET/PTT) filaments with high performances using genetic algorithm

“…To meet this demand, so-called bicomponent, tricomponent and even more filaments, combining several types of polyester have been developed. These filaments present excellent performances in terms of durability 1 , mechanical resistance 2 , 3 , water vapor permeability 4 , elastic recovery 5 , 6 , biodegradability 7 , thermal comfort 6 , etc. In this context, a new trend is emerging; it consists in using these functional filaments which have new properties for technical use.…”
