[0050] It will be appreciated that the glass slides are sterilized prior to use.

[0051] In some embodiments, before performing step S20, the mycelium membrane obtained in step S10 is gently washed with sterile water or phosphate buffered saline (PBS) to remove residual culture medium.

[0052] In some embodiments, the total volume content of ethanol and acetone in the low to high concentration dehydration solvent is between 30% and 100%. As an example, the low to high concentration dehydration solvent includes dehydration solvents with volume contents of 30%, 50%, 70%, 90% and 100%, respectively; the dehydration solvent is an ethanol-water mixed solvent or an acetone-water mixed solvent. It should be noted that a volume content of 100% means that it does not contain water, and the dehydration solvent is pure ethanol or pure acetone, or a mixture of ethanol and acetone.

[0060] If the surface of the leather substrate is too smooth, you can use fine sandpaper (400-600 mesh) to gently polish the leather surface to increase the surface roughness, thereby improving the adhesion of the mycelium film. If there is grease on the surface of the leather substrate, you can use a solution containing ethanol or isopropanol to wipe the synthetic leather surface. After treatment, let the synthetic leather surface dry naturally.

[0061] In some embodiments, the heat pressing treatment is performed using a heat press. Further, the above-mentioned flexible mycelium membrane is provided on one surface of the leather substrate.

[0070] In order to make the purpose, technical solutions and advantages of the present invention more concise and clear, the present invention is described with the following specific embodiments, but the present invention is by no means limited to these embodiments. The embodiments described below are only preferred embodiments of the present invention, which can be used to describe the present invention and cannot be understood as limiting the scope of the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0071] In order to better illustrate the present invention, the present invention is further described below in conjunction with the embodiments. The following are specific embodiments.

[0072] Example 1

[0073] 1. Strain selection: Choose Ganoderma lucidum.

[0074] 2. Preparation of mycelium membrane:

[0075] 2.1 Ganoderma lucidum strains were cultured in potato glucose medium, with an inoculation rate of 5% (volume ratio). 20 culture glass slides were prepared, sterilized and placed vertically on the culture medium at 1mm intervals; the temperature (30℃) and relative humidity (95%) were controlled, and ventilation was maintained for 7 days until the mycelium was fully grown.

[0076] 2.2 Gently wash the mycelial membrane with phosphate buffered saline (PBS) to remove the culture medium residue.

[0077] 2.3 Use ethanol-water mixed solvent for gradient dehydration: soak in 30% by volume ethanol-water mixed solvent for 15 min, 50% by volume ethanol-water mixed solvent for 15 min, and 90% by volume ethanol-water mixed solvent for 30 min.

[0078] 2.4 Choose glycerol flexibilizer, soak the dehydrated mycelium membrane in the flexibilizer solution (50g / 100mL) for 24 hours. After soaking, take out the mycelium membrane and gently absorb the excess solution on the surface with filter paper. Put it in a thermostat to control the temperature (40℃) and ventilate until it is dry.

[0079] 3. Preparation of mycelium texture leather:

[0080] 3.1 Use fine sandpaper (400 grit) to gently sand the leather (cowhide) surface to increase the surface roughness.

[0081] 3.2 Place the cleaned leather flatly on the lower mold of the hot press, lay the mycelium film obtained in step 2.4, adjust the temperature in the hot press to 50°C and the pressure to 3 MPa, hot press for 5 minutes, turn on the hot press and start hot pressing and compounding to form a composite leather with natural mycelium texture, i.e., mycelium texture leather.

[0082] After molding, a polyurethane surface coating is applied on the surface of the mycelium texture leather, which can improve the wear resistance, light resistance, aging resistance and other properties of the material surface.

[0083] Comparative Example 1

[0084] Comparative Example 1 directly uses the leather (cowhide) in Example 1.

[0085] Comparative Example 2

[0086] Comparative Example 2 is substantially the same as Example 1, except that step 2.4 is omitted, and the dehydrated mycelium membrane is directly subjected to step 3.

[0087] The following is a performance test.

[0088] Performance Test:

[0089] (1) The tensile strength performance of the mycelium texture leather prepared in the examples and comparative examples was tested. The tensile strength test was conducted in accordance with the provisions of QB / T2710-2005.

[0090] (2) The appearance of the mycelium textured leathers prepared in the examples and comparative examples was evaluated, including the texture type evaluation and the texture natural integrity evaluation.

[0091] (3) The mycelium texture leathers prepared in the examples and comparative examples were subjected to a bending heat resistance test. A circular sample with a diameter of 55 mm was cut, the base fabric was folded inward, and the bent edge was fixed with staples or U-shaped clips. The sample was placed in a 90°C heat aging thermostat for 24 h and then taken out to evaluate the surface condition of the bend.

[0092] The results are shown in Table 1 below.

[0093] Table 1

[0094]

[0095] It can be seen from Table 1 above that the mycelium textured leather prepared in the present application has a unique mycelium texture, and the texture is natural and complete and has excellent bending and heat resistance. At the same time, the tensile performance of the product is stable, which is basically equivalent to the tensile strength of the cowhide leather in Comparative Example 1, and therefore can meet the use requirements of the product.

[0096] In Comparative Example 2, the flexibilization soaking treatment step was omitted, so the obtained mycelium texture leather has a unique mycelium texture, but the mycelium texture is not natural and complete and cracks appear, indicating that the mycelium membrane is relatively brittle and has poor bendability.

[0097] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims, and the description can be used to interpret the content of the claims.
