[0023] Example 1:
[0024] A preparation method of anti-mildew vitamin fiber includes the following steps:
[0025] (1) Modification of anti-mold agent
[0026] Add the anti-fungal agent sodium diacetate to deionized water at a bath ratio of 1:3, add sodium dodecylbenzene sulfonate, stir at 50°C for 40 minutes, then add concentrated alkali, sodium hydroxide content 4wt%, stir for 120 minutes , Prepare a modified antifungal agent.
[0027] (2) Preparation of blended spinning solution: Using cellulose pulp as raw material, the viscose collagen solution is prepared by conventional viscose preparation technology. In the dissolution step of the viscose collagen solution, the modified anti-mold prepared in (1) above is added After stirring for 60 minutes, add melamine formaldehyde resin to prepare a blended spinning solution.
[0028] The quality of the anti-fungal agent added in (2) is calculated based on the effective ingredients and added to account for 1wt% of the A cellulose content in...

[0049] Example 3:
[0050] A preparation method of anti-mildew vitamin fiber includes the following steps:
[0051] (1) Modification of anti-mold agent
[0052] Add the imidazole antifungal agent to deionized water at a bath ratio of 1:5, add polyethylene glycol, stir at 60°C for 40 minutes, add concentrated alkali, sodium hydroxide content 6wt%, stir for 60 minutes, and prepare the modified Antifungal agent.
[0053] (2) Preparation of blended spinning solution: Using cellulose pulp as raw material, the viscose collagen solution is prepared by conventional viscose preparation technology. In the dissolution step of the viscose collagen solution, the modified anti-mold prepared in (1) above is added After stirring for 60 minutes, a blended spinning solution was prepared. The melamine formaldehyde resin is added through the pre-spinning injection system to prepare a spinning glue with anti-mildew properties.
