Embodiment 1

[0012] (1) Hydrolyzed acrylic fiber: take the acrylic fiber and add it into a 1% NaOH aqueous solution at a temperature of 60° C. at a bath ratio of 1:6, hydrolyze for 20 minutes, take it out, wash it and dry it to obtain the hydrolyzed acrylic fiber.

[0013] (2) According to step (1) 3% of the obtained hydrolyzed acrylic fiber quality gets thionyl chloride and joins in the open glass vessel, puts the glass vessel in the airtight container, then puts the hydrolyzed acrylic fiber into the above-mentioned airtight container ,seal. The airtight container was heated up to 80° C., reacted for 60 minutes, and the airtight container was opened to obtain acyl chloride fiber.

[0014] (3) Soybean juice uses 50-mesh filter to remove residue raw soybean juice, adjust the pH value of the soybean juice to 8, heat up to 60°C, put the acyl chloride fiber into the soybean juice at a bath ratio of 1:5, stir for 30 minutes, take out After washing and drying, the protein-grafted modified acryl...

Embodiment 2

[0016] (1) Hydrolyzed acrylic fiber: take the acrylic fiber and add it into a 100° C. NaOH aqueous solution with a concentration of 10% in a bath ratio of 1:10, hydrolyze it for 10 minutes, take it out, wash it and dry it to obtain the hydrolyzed acrylic fiber.

[0017] (2) Add thionyl chloride to an open glass vessel according to 10% of the quality of the hydrolyzed acrylic fiber obtained in step (1), put the glass vessel into a closed container, and then put the hydrolyzed acrylic fiber into the above-mentioned closed container ,seal. The airtight container was heated up to 110° C., reacted for 20 minutes, and the airtight container was opened to obtain acyl chloride fiber.

[0018] (3) Soybean juice uses 80-mesh filter to remove residue raw soybean juice, adjust the pH of the soybean juice to 10, heat up to 80°C, put the acyl chloride fiber into the soybean juice at a bath ratio of 1:15, stir for 15 minutes, take out After washing and drying, the protein-grafted modified a...

Embodiment 3

[0020] (1) Hydrolyzed acrylic fiber: take the acrylic fiber and add it into a KOH aqueous solution with a temperature of 120°C and a concentration of 30% at a bath ratio of 1:20, hydrolyze it for 2 minutes, take it out, wash it and dry it to obtain the hydrolyzed acrylic fiber.

[0021] (2) Add thionyl chloride to an open glass vessel according to 20% of the quality of the hydrolyzed acrylic fiber obtained in step (1), put the glass vessel into a closed container, and then put the hydrolyzed acrylic fiber into the above-mentioned closed container ,seal. The airtight container was heated up to 140° C., reacted for 3 minutes, and the airtight container was opened to obtain acyl chloride fiber.

[0022] (3) Soybean juice uses 120-mesh filter to remove residue raw soybean juice, adjust the pH value of soybean juice to 13, heat up to 100°C, put acyl chloride fiber into soybean juice at a bath ratio of 1:30, stir for 2 minutes, take out After washing and drying, the protein-grafted...

Abstract

The invention relates to a manufacturing method of protein modified fiber in acrylic fiber surface ingrafted bean juice, which is characterized by comprising the following steps: (1) firstly, putting acrylic fiber into alkaline aqueous solution at certain bath ratio, certain mass ratio density and temperature, and hydrolyzing for a certain time; (2) cleaning and drying to obtain hydrolyzed fiber, and causing the hydrolyzed fiber to react with thionyl chloride to obtain chlorination fiber; and (3) putting the chlorination fiber into the bean juice to be ingrafted into fiber of which the surface is covered with a bean juice protein layer. The invention utilizes the ingrafted and modified method of protein on the acrylic fiber surface in the bean juice to realize protein surface modified efficacy of the acrylic fiber in the bean juice, and the human body affinity, hygroscopicity and antistatic property of fiber can be improved. The method of the invention is simple and feasible, can realize industrial production only by simple fiber aftertreatment equipment and has the characteristics of small production investment, low production cost and the like.

Description

technical field [0001] The invention relates to a method for producing protein-modified fibers grafted on the surface of acrylic fibers in soybean juice, and belongs to the technical field of fiber production. Background technique [0002] Acrylic fiber is a kind of synthetic fiber, which has the characteristics of excellent warmth retention, dyeability and wool-like property, but it also has many disadvantages, such as poor hydrophilicity, easy generation of static electricity, and poor human affinity. In order to improve the performance of acrylic fibers, researchers have used various methods to modify acrylic fibers with animal and plant proteins, such as silk protein and milk protein grafted with polyacrylonitrile and then spun to make modified acrylic fibers; animal and plant proteins and polyacrylonitrile Blend spinning etc. A common feature of these methods is that it is necessary to build a large-scale fiber spinning production line to produce, so the investment cos...
