Method for manufacturing honeycomb core filled with fibrofelt by using textile wastes

Abstract

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.

Description

technical field [0001] The invention relates to a method for making a honeycomb core filled with fiber mats from textile waste. It belongs to the cross technical field of circular economy and building decoration materials. Background technique [0002] Circular economy refers to the general term for the reduction, reuse and recycling activities in the process of production, circulation and consumption. Reuse includes using all or part of waste as components of other products; resource utilization refers to using waste directly as raw materials or reusing waste. The invention relates to a method for making a honeycomb core by hot-pressing and compounding textile waste materials, which belongs to the technical field of recycling and recycling in circular economy. my country's textile fiber processing volume is about 30 million tons per year, accounting for more than 40% of the global textile fiber processing volume. The huge amount of textile fiber processing makes the accu...

Problems solved by technology

The inner hole medium of the honeycomb panel is air. Although each honeycomb unit is an independent space, there is no convection with the adjacent honeycomb unit, and there is a certain degree of heat preservation, but the inner space of the two panels in each unit space still produces convection. Therefore, its thermal insulation performance is relatively poor, and the sound insulation performance is even worse, mainly relying on the two panels to play the role of sound insulation.

Therefore, these honeycomb panels are far from meeting the needs of modern engineering
