Abstract
The objective of this research is the development of a magnetic sheath-core bicomponent fiber. Therefor technical oxide is mixed in polypropylene using compounding. The compound (sheath) and pure polypropylene (core) are further processed in melt spinning into a magnetic bicomponent fiber with textile strength of 26.36 ± 1.62 cN/tex. Bicomponent fiber yarns can be inductively heated above 175°C in less than 10 s. These fibers could be used for thermal bonding of fiber-reinforced plastics, joining techniques of high efficiency due to their possibility to form a material-bonded connection and fiber orientation in nonwovens through a directional magnetic field.Graphical
