The invention discloses a method for manufacturing a
honeycomb core filled with fibrofelt by using
textile wastes, which is characterized by comprising the following steps: (1) manufacturing of flat-head waved fiberboards and
honeycomb-shaped fibrofelt strips by using
textile wastes, that is, recovering
textile wastes into reprocessing fibers, wherein the
thermoplastic textile wastes are well mixed with common textile wastes in proportion; preparing
fiber nets, performing
hot pressing of the prepared
fiber nets respectively, preparing flat-head waved fiberboards and broken-line waved fibrofelt,
cutting the fibrofelt to obtain
honeycomb-shaped fibrofelt strips; (2) bonding and
cutting of the fiberboards and fibrofelt, that is,
coating adhesive tapes on peaks and troughs of the fiberboards prepared in step (1), pasting the fibrofelt strips obtained in step (1) on the troughs of the fiberboards, bonding the fiberboards on the fibrofelt strips, repeating the bonding in the above manner to obtain a honeycomb core complex;
cutting the complex at the cross section to obtain the honeycomb core filled with fibrofelt. The method can make use of hard textile wastes, and the honeycomb core and the filling material have accurate structures, and improved heat insulation and sound insulation performance.
