Embodiment 1

[0025] Wheat protein fiber, the protein content in the fiber accounts for 48.2% of the total fiber weight, and the cellulose content accounts for 51.8% of the total fiber weight.

[0026] Prepared by the following method:

[0027] (1) Separation process of alkali cellulose in bran

[0028] Soak wheat bran in 5% NaOH solution with a bath ratio of 1:4, fully stir at 40°C, and separate the large slag through a spiral to obtain alkali cellulose slurry A1.

[0029] (2) Prolamin preparation process

[0030] Mix gluten with ethanol solution with a volume concentration of 65%, and stir for 4 hours at a temperature of 40°C to dissolve prolamin into the ethanol solution. After filtering, the filtered liquid is distilled to recover part of the alcohol, and the rest is Prolamin Latex A2.

[0031] (3) Preparation process of glutenin latex

[0032] Glutenin latex A3 was prepared by filtering the gliadin-removed gluten powder and then dissolving the remaining slag in 4% NaOH aqueous sol...

Embodiment 2

[0044] Wheat protein fiber, the protein content in the fiber accounts for 75% of the total fiber weight, and the cellulose content accounts for 25% of the total fiber weight.

[0045] Prepared by the following method:

[0046] (1) Separation process of alkali cellulose in bran

[0047] Soak wheat bran in 3% NaOH solution with a bath ratio of 1:5, fully stir at 40°C, and separate the large slag through a spiral to obtain alkali cellulose slurry A1.

[0048] (2) Prolamin preparation process

[0049] Mix gluten with ethanol solution with a volume concentration of 65%, and stir for 7 hours at a temperature of 25°C. The prolamin is dissolved in the ethanol solution, filtered, and the filtered liquid is distilled to recover part of the alcohol, and the remaining part is Prolamin Latex A2.

[0050] (3) Preparation process of glutenin latex

[0051] Glutenin latex A3 was prepared by filtering the gliadin-removed gluten powder and dissolving it in 4% NaOH aqueous solution at a dis...

Embodiment 3

[0060] Wheat protein fiber, the protein content in the fiber accounts for 28.2% of the total fiber weight, and the cellulose content accounts for 71.8% of the total fiber weight.

[0061] Prepared by the following method:

[0062] (1) Separation process of alkali cellulose in bran

[0063]Soak wheat bran in 6% NaOH solution with a bath ratio of 1:3, fully stir at 40°C, and separate the large slag through a spiral to obtain alkali cellulose slurry A1.

[0064] (2) Prolamin preparation process

[0065] Mix gluten with ethanol solution with a volume concentration of 65%, and stir for 2 hours at a temperature of 70°C to dissolve prolamin into the ethanol solution. After filtering, the filtered liquid is distilled to recover part of the alcohol, and the rest is Prolamin Latex A2.

[0066] (3) Preparation process of glutenin latex

[0067] Glutenin latex A3 was prepared by filtering the gliadin-removed gluten powder and then dissolving it in 4% NaOH aqueous solution at a dissol...

Abstract

The invention belongs to the technical field of spinning and particularly relates to a wheat protein fiber and a manufacturing method thereof. The protein content in the fiber accounts for 0.1-55% of the total weight of the fiber, and the cellulose content accounts for 45-99.9% of the total weight of the fiber. The process disclosed by the invention is simple, and a product has the advantages of soft and smooth hand feeling, skin-friendly and skin-moistening properties, bright and amiable appearance and bright and full dyeing, and further becomes an ideal modern textile raw material.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a wheat protein fiber and a manufacturing method thereof. Background technique [0002] Many varieties of vegetable protein fibers and animal protein fibers are currently on the market. For example, Chinese patent applications 01131920.8, 02109966.9, 200410010327.3, and 03135631.1 describe the production methods of protein fibers such as soybeans and silkworm chrysalis, respectively. However, no matter which type of protein is selected, it needs to be spun in combination with other fiber-forming substances, such as milk fiber mixed with polyacrylonitrile to obtain milk fiber, soybean mixed with polyvinyl alcohol to obtain soybean protein fiber, silkworm chrysalis and cellulose Viscose is mixed to obtain silkworm chrysalis protein fibers, etc. The introduction of protein can effectively improve the properties of the fibrils, improve the softness and skin-friendly properties of th...
