Embodiment Construction

[0019] The present invention will be described below in conjunction with specific embodiments.

[0020] This embodiment relates to a specific method for processing a honeycomb core with textile waste, comprising the following process steps:

[0021] (1) Production of reprocessed fiber felt

[0022] Textile waste is mainly made of ordinary clothing scraps and polypropylene waste silk, polypropylene waste silk is the bonding fiber, and ordinary clothing corner waste is the main fiber. The ratio of raw materials (that is, the content of binder fiber and main fiber) directly affects the characteristics of the product, and the content of polypropylene waste silk is 40%-50%. The opening and mixing of textile wastes takes into account the different sizes and lengths of raw materials, especially the characteristics that polypropylene waste silk is not easy to open and wind around cylinders during the tearing process, and polypropylene waste silk and waste spinning fibers are easily m...

Abstract

The present invention discloses a method for producing a honeycomb core with a textile waste material, which is characterized by including: 1) treatment of the textile waste material and production of fiber felt, including cutting up the textile waste material, tearing, fully mixing a thermoplasticity textile waste material with an ordinary textile waste material in proportion to produce re-processed fibers, performing net formation and hot melting reinforcement of the fibers to obtain a fiber felt; 2) production of a fiberboard and a honeycomb core blank, including preheating and molding the fiber felt obtained from the 1) step to obtain the fiberboard, coating a binder according to a certain rule on the fiberboard to form binder strips, bonding a plurality of layers of fiberboards to produce the honeycomb core blank; and 3) processing the honeycomb core, including cutting the honeycomb core blank obtained from the 2) step into the honeycomb core blank strips with an equal width, preheating the honeycomb core blank strips, and stretching at the cross-section by segments to make the honeycomb core blank strips expand, so as to obtain the honeycomb core with the textile waste material. The method can make use of rigid textile waste materials with large quality discrepancy, the different fibers in the textile waste material do not need to be distinguished, and the added value of the textile waste material is increased.

Description

technical field [0001] The invention relates to a 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] The "Circular Economy Promotion Law", which came into effect on January 1, 2009, clearly states that circular economy refers to the general term for reduction, reuse, and resource-based activities in the processes of production, circulation, and consumption. The so-called reuse refers to using waste directly as a product or continuing to use it as a product after repairing, refurbishing, or remanufacturing, or using all or part of the waste as components of other products; the so-called recycling of waste refers to the use of waste Utilize directly as raw materials or recycle waste. The method for making honeycomb cores from textile wastes involved in the invention belongs to the technical field of recycling and recycling in circular economy. my ...
