Simple method for manufacturing honeycomb core by textile wastes

Abstract

The invention discloses a simple method for manufacturing a honeycomb core by textile wastes, which is characterized in that the method comprises the following steps of: (1) manufacturing of a fiber board spaced by fibrofelt by using textile wastes, that is, firstly cutting and opening textile wastes to recover the textile wastes into reprocessing fibers, wherein thermoplastic textile wastes is well mixed with common textile wastes in proportion; preparing a fiber net by using the obtained reprocessing fibers; preheating the prepared fiber net, molding with a mold with grooves, cooling to obtain the fiber board spaced by fibrofelt; (2) processing of a honeycomb core blank, that is, coating adhesive tapes on the fiber board spaced by fibrofelt manufactured in step (1), bonding together layer by layer to obtain the honeycomb core blank; (3) processing of the honeycomb core: cutting the honeycomb core blank obtained in step (2) into honeycomb core blank strips with a required height, stretching at the cross sections, expending the honeycomb core blank strips to obtain the honeycomb core. The method can make use of hard textile wastes, and the honeycomb core is easy to mold, accurate in structure, and simple in process.

Description

technical field [0001] The invention relates to a simple method for making a honeycomb core 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 accumulation of text...

Problems solved by technology

This kind of processing is through mechanical cutting, tearing, and opening to make the fibers untwisted. Due to the severe processing process, it is easy to break and damage the fibers. Therefore, the reprocessed fibers are short in length, miscellaneous in variety, many in color and poor in quality. Therefore, the current utilization of reprocessed fiber is very limited, and it is generally used as various filling and thermal insulation materials, with low added value.
