Description

Preparation Method for Mushroom Pulp The present invention relates to a method for manufacturing mushroom pulp. Conventional fiber materials made from synthetic polymers, such as polyester and nylon, do not decompose in nature and cause environmental problems. To address this issue, research on biodegradable materials, particularly eco-friendly alternatives, is actively underway. Among these, research utilizing mushrooms is attracting significant attention. Mushrooms are considered an ideal substitute in the textile and other materials industries due to their biodegradability and the ability to be recycled as resources. Ecovative Design in the United States is developing various products, such as leather materials, insulation, and packaging materials, using mushroom mycelium, and several global companies are also expanding their research using mushrooms. Such mushroom-based research holds high value in the materials industry while reducing environmental impact. However, research on fiber manufacturing using mushroom fruiting bodies and mycelia has been scarce. Consequently, the development of new fiber materials utilizing mushrooms can secure novelty and innovation. In particular, economic benefits are expected by reducing raw material costs and solving environmental issues through the recycling of non-commercial fruiting bodies generated during the mushroom cultivation process or the base of mushrooms after cultivation. The present invention presents a technology for producing eco-friendly mushroom pulp by treating mushroom fruiting bodies and mycelia with alkali and bleaching. Through this, a material capable of replacing synthetic fibers is created, and the whiteness and physical properties of the mushroom pulp are optimized by using various bleaching agents. This pulp can also be applied to the nonwoven fabric manufacturing process.

Figure 9 is a summary of the nonwoven fabric and tensile strength analysis results produced through the nonwoven fabric manufacturing process of <Example 2>. The present invention will be described in detail below. The present invention relates to a method for manufacturing mushroom pulp. The method of the present invention comprises the steps of: treating mushrooms with an alkaline aqueous solution; bleaching the mushrooms treated with the alkaline aqueous solution; and dispersing the bleached mushrooms in a dispersion medium. A "mushroom" is a living organism belonging to the fungi class, which can be broadly divided into a fruiting body and a mycelium. First, the fruiting body refers to the reproductive growth organ formed for the reproduction of the mushroom; it essentially represents the part consumed by humans and is characterized by generally forming outside the substrate or on the surface. The mycelium refers to the vegetative growth organ formed to absorb nutrients required for growth; it generally exists between or within the substrate and is characterized by a three-dimensional porous network structure. Compared to ordinary plants, the fruiting body corresponds to the flower, while the mycelium corresponds to the stem, roots, and leaves excluding the flower. Both the fruiting body and the mycelium are formed by single strands called hyphae intertwining with one another. The mushroom may be a fruiting body or mycelium of one species selected from the group consisting of, for example, Trametes versicolor , Pleurotus ostreatus , Wolfiporia extensa, Trametes orientalis , Agaricus bisporus , Ganoderma lucidum , Fomitella fraxinea , Schizophyllum commune , Lentinula edodes , Flammulina velutipes , and Agaricus bisporus . For example, the Sirusongpyeon mushroom may be treated with gamma rays. The gamma rays may be irradiated with gamma rays of, for example, 100 to 300 Gy, 150 to 250 Gy, etc., for 1 to 5 hours, 1 to 3 hours, etc. The mushrooms may have been washed. The alkaline aqueous solution may be, for example, an aqueous sodium hydroxide solution with a concentration of 0.5 to 10 weight%, 2 to 8 weight%, 3 to 7 weight%, 4 to 6 weight%, or 4.5 to 5.5 weigh
