Description
Technical Field
The invention relates to the field of bedding, in particular to loofah sponge carbon powder, a loofah sponge carbon-based foaming material, application of the loofah sponge carbon-based foaming material and a pillow.
Background
The common pillow filling materials in the market at present mainly comprise memory sponge, latex and plant filling materials (such as buckwheat, cassia seeds and tea leaves), wherein the market share of the memory sponge and the latex pillow is large, but because the air permeability and the moisture dissipation of the pillow core material are poor, sweat and water vapor generated by a human body in the sleeping process cannot be timely removed, and the human body is very easy to generate sticky and stuffy feeling, so that the sleeping quality is influenced. Meanwhile, the pillow with poor air permeability and moisture dispersion property is easy to breed mites and other bacteria, and causes damage to the skin and other parts. In addition, the traditional memory sponge has the phenomena of easy tearing, easy yellowing and the like, so that the service life of the memory sponge material is greatly reduced.
The retinervus Luffae fructus is mature vascular bundle of Cucurbitaceae plant retinervus Luffae fructus, and has three-dimensional network structure and good air permeability. The product of the loofah sponge pyrolysis is loofah sponge carbon, the unique pore structure of the loofah sponge carbon is formed by the evolution of the original pore structure of the loofah sponge, and the pore diameter of the loofah sponge carbon is about 5 mu m. Therefore, the loofah sponge carbon has a developed capillary pore system, so that the loofah sponge carbon has excellent functions of temperature regulation and humidity regulation, and is beneficial to developing health care products. In addition, the loofah sponge carbon can also emit negative ions and far infrared rays, and can promote the activation of human cells, improve blood circulation and eliminate the sense of physical fatigue when being absorbed by a human body. Meanwhile, due to the non-uniformity of the natural cylindrical luffa, a large amount of luffa leftover materials are directly discarded in the processing process, and the waste luffa leftover materials can cause environmental pollution by burning. The loofah sponge carbon can be obtained by pyrolyzing leftover materials in loofah sponge processing, so that the utilization rate of the loofah sponge can be effectively improved, and the resource waste is reduced.
Therefore, the loofah sponge can be used for synthesizing the memory sponge by preparing the loofah sponge carbon powder, and the produced loofah sponge carbon memory sponge is safe and sanitary and can also show better mechanical property, air permeability and moisture dissipation property, mite prevention and bacteria prevention property and yellowing resistance property.
