Bicomponent fiber equipment

Bicomponent fibers can be divided into several different categories as shown in the chart in Fig. 3.5. These variants are discussed as follows (Hills, Inc., 2011). 

A first type of sheath/core is self-bonding fibers consisting of a low melting temperature sheath and a higher melting temperature core. Common

It is very difficult to define the exact worldwide production capacity for bicomponent fibers. Most machines are extruder fed, and many machines in Asia were made locally and are not always successful in making good products. Also, many machines that have bicomponent capability are used to run standard homopolymer products. However, it is estimated that approximately 2-3% of worldwide synthetic fiber production equipment has bicomponent capacity. Of this capacity, approximately 23% for filament yams, 31 % for staple yarns, and 46% for spunbond. Approximately 75% of bicomponent fibers go to a nonwoven end use.
