1. Definition and classification of bi/tricomponent fibers
Bi/tricomponent fibers are fibers that have been extruded and then spun on the same spinneret with two or three polymers, with a cross-sectional shape specific to the fiber's intended use. The two polymers differ in their physico-chemical characteristics, such as molecular weight.
We often speak of "bicomponent fibers", even if today new tricomponent machines are appearing in laboratories and industries.
1.1 Side-by-side or side-by-side fibers
Side-by-side fibers comprise two polymer components positioned side by side (figure 1 ). Typically, the two components of these fibers are distributed...
