Problems solved by technology

These so-called plant fiber materials are used to fill sofa cushions, usually by destroying the tissue structure of the plant material itself, extracting the plant fibers, bonding them with an adhesive, and then hot-pressing them. The waste of resources is serious, and there are also a series of problems in such materials. For example, bamboo filaments have been briquetted to produce bamboo filament unit design and production of filling materials. This treatment method destroys the natural structure of bamboo, and it is necessary to use adhesives or low-melting point polyester fibers to bond the dispersed bamboo filaments to make boards. , the prepared board has high hardness and low elasticity, resulting in poor sitting comfort, poor air permeability, etc., and even contains toxic substances such as formaldehyde

Abstract

The invention provides a bamboo spring sofa, comprising a base and a backrest, characterized in that the sofa seat surface of the base is provided with a bamboo spring support structure, and the support structure includes an elastic support layer arranged on the base frame and An elastic comfort layer arranged on the elastic support layer; the core layer of the elastic support layer is composed of an inner bladder cover and a plurality of bamboo spring units wrapped on the inner bladder cover, and each bamboo spring unit is independent The bag-packed structure includes a bamboo spring body and a non-woven bag covering the bamboo spring body respectively; wherein, the bamboo spring body is prepared by a winding and shaping process after improving its physical and mechanical properties through quantitative impregnation treatment. The bamboo spring sofa of the invention has the advantages of ventilation and moisture dissipation, antibacterial and antibacterial, green, low-carbon and environmental protection, and at the same time, it can meet the quantitative support requirements of people of different body shapes and weights.

Description

technical field [0001] The invention relates to the technical field of sofas, in particular to a kind of bamboo material used as a raw material, whose organizational structure is quantitatively regulated by chemical modification, its physical and mechanical properties are improved by quantitative impregnation treatment, and a bamboo spring filling material is prepared by processes such as winding and shaping, etc. The healthy and environmentally friendly bamboo spring sofa seat surface support structure, backrest support structure and sofa developed using this material can meet the quantitative support and comfort requirements of people of different body shapes and weights. Background technique [0002] During the use of the sofa, the support structure of the sofa seat is the main force-bearing part, and the support structure of the sofa seat determines the comfort and service life of the sofa. [0003] At present, the load-bearing methods of the sofa seat support structure ...
