Embodiment 1

[0021] In this embodiment, the self-cleaning wool keratin fiber membrane is prepared by the following method, including the following steps:

[0022] (1) Selection of waste wool: select waste wool discarded from the factory, wash it with a clothing detergent, and then wash it with a lot of water and dry it.

[0023] (2) Extraction of wool keratin: Weigh 10g of waste wool, add 1500mL dissolved NaHSO 3 / LiBr / sodium lauryl sulfate mixed aqueous solution to dissolve, NaHSO in the mixed aqueous solution 3 The mass fractions of, LiBr and sodium lauryl sulfate are respectively: 3%, 5% and 4%, adjust the pH to 9, set the temperature to 70°C, and react for 5 hours under nitrogen to obtain a wool keratin solution. The dialysis bag with a molecular weight of 12000 was dialyzed with flowing water for 36 hours, and then dialyzed with deionized water for 18 hours to obtain a purified wool keratin solution.

[0024] (3) Preparation of powdered wool keratin: freeze-dry the wool keratin solution prep...

Embodiment 2

[0029] In this embodiment, the self-cleaning wool keratin fiber membrane is prepared by the following method, including the following steps:

[0030] (1) Selection of waste wool: select waste wool discarded from the factory, wash it with a clothing detergent, and then wash it with a lot of water and dry it.

[0031] (2) Extraction of wool keratin: Weigh 10g of waste wool, add 1000mL dissolved NaHSO 3 / LiBr / sodium lauryl sulfate mixed aqueous solution to dissolve, NaHSO in the mixed aqueous solution 3 The mass fractions of, LiBr and sodium lauryl sulfate are respectively: 2%, 4% and 3%, adjust the pH to 8, set the temperature to 60℃, and react for 4h under nitrogen to obtain the wool keratin solution. The dialysis bag with a molecular weight of 10,000 was dialysis for 24 hours with flowing water, and then with deionized water for 12 hours to obtain a purified wool keratin solution.

[0032] (3) Preparation of powdered wool keratin: freeze-dry the wool keratin solution prepared in step...

Embodiment 3

[0037] In this embodiment, the self-cleaning wool keratin fiber membrane is prepared by the following method, including the following steps:

[0038] (1) Selection of waste wool: select waste wool discarded from the factory, wash it with a clothing detergent, and then wash it with a lot of water and dry it.

[0039] (2) Extraction of wool keratin: Weigh 10g of waste wool and add 2000mL dissolved NaHSO 3 / LiBr / sodium lauryl sulfate mixed aqueous solution to dissolve, NaHSO in the mixed aqueous solution 3 The mass fractions of, LiBr and sodium lauryl sulfate are respectively: 4%, 6% and 5%, adjust the pH to 10, set the temperature to 80℃, and react for 6h under nitrogen to obtain the wool keratin solution. The dialysis bag with a molecular weight of 16000 was dialyzed with flowing water for 48 hours, and then dialyzed with deionized water for 24 hours to obtain a purified wool keratin solution.

Abstract

The invention relates to a self-cleaning wool keratin fiber film material and a preparation method thereof. The film material can be prepared through the following preparation method comprising the following steps that waste wool is cleaned firstly, then the waste wool is dissolved, moreover, wool keratin in the waste wool is extracted, freeze drying is performed on a wool keratin solution, the dried wool keratin is ground to form powder, the powdered wool keratin is dissolved in an organic solvent to prepare a film forming emulsion, and impregnation, lifting and solvent evaporation process flows are performed on the film forming emulsion to prepare the self-cleaning wool keratin fiber film material. The preparation process of the self-cleaning wool keratin fiber film material prepared bythe method is simple, the stain resistance of the film material is high, the self-cleaning performance of the film material is good, and the film material has a quite good application prospect in thetextile field.

Description

Technical field [0001] The invention belongs to the technical field of membrane materials, and specifically relates to a self-cleaning wool keratin fiber membrane material and a preparation method thereof. Background technique [0002] The application of textile membrane materials in textile and clothing materials has attracted more and more attention. At present, textile membrane materials mainly include polyethylene diether (PEO), polyethylene (PCL), polytetrafluoroethylene (PTFE), and polyurethane formic acid. Ester (PU) and so on. Textile membranes are mainly used in the textile field as follows: First, it can be used as the raw material for the preparation of membrane laminated fabrics; Second, the membrane is combined with knitted fabrics, plain fabrics, films, and non-woven fabrics through ultra-thin film special adhesives. Adhesive lamination enables the fabric to obtain special properties; third, it is used on the fabric to make the fabric have moisture permeability and...
