Embodiment 1

[0016] For realizing above-mentioned technical effect, the production technology of elastic worsted fabric anti-ultraviolet finishing solution in embodiment 1 comprises the following steps:

[0017] S1: Prepare wool keratin solution, immerse wool in imidazole-type ionic liquid, heat to 60°C under vacuum, keep stirring until the wool is completely dissolved into a beige liquid;

[0018] S2: preparing a sodium carboxymethyl cellulose solution, stirring and dissolving the sodium carboxymethyl cellulose powder in water at 45°C to prepare a sodium carboxymethyl cellulose solution with a concentration of 0.5% by weight;

[0019] S3: The wool keratin solution obtained in S1 is miscible with water in a ratio of 1:7, and the sodium carboxymethyl cellulose solution obtained in S2 is added. The volume ratio of the sodium carboxymethyl cellulose solution to water is 0.1:1, and then added to the A cross-linking agent is added into the mixed solution to obtain a wool keratin finishing solut...

Embodiment 2

[0024] The difference between embodiment 2 and embodiment 1 is:

[0025] S1: Heating to 80°C under vacuum;

[0026] S2: stirring and dissolving the sodium carboxymethyl cellulose powder in water at 50°C to prepare a sodium carboxymethyl cellulose solution with a concentration of 0.7% by weight;

[0027] S3: The wool keratin solution obtained in S1 is miscible with water at a ratio of 1:10, and the volume ratio of sodium carboxymethyl cellulose solution to water is 0.3:1.

[0028] Imidazole-type ionic liquid is a mixture of 1-butyl-3-methylimidazolium bromide and 1-butyl-3-methylimidazolium tetrafluoroborate. In imidazole-type ionic liquid, 1-butyl-3-methyl The weight ratio of imidazolium bromide is 30%.

[0029] The weight ratio of wool and ionic liquid mixed solution in S2 is 1:15.

[0030] The weight percent concentration of the crosslinking agent in the wool keratin finishing solution is 0.8%.

[0032] The difference between embodiment 3 and embodiment 1 is:

[0033] S1: Heating to 70°C under vacuum;

[0034] S2: stirring and dissolving the sodium carboxymethyl cellulose powder in water at 47°C to prepare a sodium carboxymethyl cellulose solution with a concentration of 0.6% by weight;

[0035] S3: The wool keratin solution obtained in S1 is miscible with water at a ratio of 1:8, and the volume ratio of sodium carboxymethylcellulose solution to water is 0.2:1.

[0036] Imidazole-type ionic liquid is a mixture of 1-butyl-3-methylimidazolium bromide and 1-butyl-3-methylimidazolium tetrafluoroborate. In imidazole-type ionic liquid, 1-butyl-3-methyl The weight ratio of imidazolium bromide is 40%.

[0037] The weight ratio of wool and ionic liquid mixed solution in S2 is 1:12.

[0038] The weight percent concentration of the crosslinking agent in the wool keratin finishing solution is 0.7%.

Abstract

The invention discloses a production process of an anti-ultraviolet finishing solution for elastic worsted fabrics, which comprises the steps of preparing a wool keratin solution, preparing a sodium carboxymethyl cellulose solution, preparing a finishing solution, and the like. The anti-ultraviolet finishing solution for elastic worsted fabrics of the present invention can form a uniform and elastic film on the surface of fabric fibers, has good mechanical properties, suitable tensile strength, and large elongation at break, and can be compatible with elastic worsted fabrics to avoid The phenomenon that fiber elongation affects film adhesion due to elastic deformation of the fabric helps to maintain the long-term UV resistance of the fabric.

Description

technical field [0001] The invention relates to the technical field of finishing liquid for textiles, in particular to a production process of an anti-ultraviolet finishing liquid for elastic worsted fabrics. Background technique [0002] Wool keratin and tryptophan and tyrosine in the keratin solution contain a large number of unsaturated double bonds, which can cause the transition of valence electrons, thereby increasing the yarn's absorption rate of ultraviolet rays. Therefore, wool keratin solutions are often used in the optimization of UV resistance of cotton fabrics. Keratin molecules can be cross-linked to form films through hydrogen bonds, salt bonds, and disulfide bonds, and have a strong film-forming ability. However, pure keratin films are rigid and hard, and are easily broken under dry conditions, which greatly limits In its application field, the research on the modification of pure keratin film is imperative. Polymer blending, as the most commonly used prote...
