Embodiment 1
[0029] Preparation of Chitin Nonwoven Substrate:
[0030] The preparation method of the base layer comprises the following steps:
[0031] (1) Preparation of colloid: Purified chitin and an acid solution with a mass percentage concentration of 80% are prepared into a colloid solution with a mass percentage concentration (w / w) of 10%; the acid solution includes formic acid, acetic acid, and propionic acid one or more of them;
[0032] (2) Wire drawing: put the above colloidal solution and hydroxyethyl cellulose into a pressure-resistant stainless steel tank according to the weight ratio of 10:1, and then pour inert gas into the pressure-resistant stainless steel tank so that the pressure of the inert gas is 0.1 MPa, Keep it for 30-60 minutes, and then restore the normal pressure in the storage tank; draw the colloid solution through a wire drawing machine, and after drawing, contact with ethanol to deacidify and solidify into chitin silk threads;
[0033] (3) Deacidification:...
Embodiment 2
[0037] Preparation of Chitin Nonwoven Substrate:
[0038] The preparation method of the base layer comprises the following steps:
[0039] (1) Preparation of colloid: Purified chitin and an acid solution with a mass percentage concentration of 80% are prepared into a colloid solution with a mass percentage concentration (w / w) of 22%; the acid solution includes formic acid, acetic acid, and propionic acid one or more of them;
[0040] (2) Wire drawing: put the above colloidal solution and hydroxyethyl cellulose into a pressure-resistant stainless steel tank according to the weight ratio of 10:1, and then pour inert gas into the pressure-resistant stainless steel tank so that the pressure of the inert gas is 0.1 MPa, Keep it for 30-60 minutes, and then restore the normal pressure in the storage tank; draw the colloid solution through a wire drawing machine, and after drawing, contact with ethanol to deacidify and solidify into chitin silk threads;
[0041] (3) Deacidification:...
Embodiment 3
[0045] Preparation of Chitin Nonwoven Substrate:
[0046] The preparation method of the base layer comprises the following steps:
[0047] (1) Preparation of colloid: Purified chitin and an acid solution with a mass percentage concentration of 80% are prepared into a colloid solution with a mass percentage concentration (w / w) of 25%; the acid solution includes formic acid, acetic acid, and propionic acid one or more of them;
[0048] (2) Wire drawing: put the above colloidal solution and hydroxyethyl cellulose into a pressure-resistant stainless steel tank according to the weight ratio of 10:1, and then pour inert gas into the pressure-resistant stainless steel tank so that the pressure of the inert gas is 0.1 MPa, Keep it for 30-60 minutes, and then restore the normal pressure in the storage tank; draw the colloid solution through a wire drawing machine, and after drawing, contact with ethanol to deacidify and solidify into chitin silk threads;
