preparation example Construction

[0033] According to one aspect of the present invention, the present invention provides a kind of preparation method of colored active organic functional fiber of five grains, comprising the following steps:

[0034] (a) uniformly mixing the vegetable protein solution, the polyvinyl alcohol solution and the color paste to obtain a spinning stock solution;

[0035] (b) Spinning the spinning dope to obtain nascent fibers;

[0036] (c) performing wet-heat drafting and dry-heat drafting sequentially on the as-spun fibers to obtain drawn fibers;

[0037] (d) subjecting the stretched fiber to cross-linking and color-fixing treatment to obtain five-grain colored active organic functional fiber.

[0038] In the present invention, vegetable protein includes isolated protein extracted from soybeans, peanuts, cottonseed or rapeseed by soaking, wet grinding, or directly from soybeans, peanuts, cottonseed or rapeseed through crushing, degreasing, soaking or Protein isolates extracted fro...

Embodiment 1

[0094] The present embodiment provides a kind of preparation method of blue soybean protein fiber, comprises the steps:

[0095] (1) Soybean protein and water are added in the dissolving machine, then in the dissolving machine, adding a concentration of 10% sodium hydroxide solution, the dissolving machine is stirred at a speed of 45r / min, and the dissolving machine is heated up to 85 ℃, stirred for 6 hours to obtain a soybean protein solution with a concentration of 6-10%, and then kept the soybean protein solution for 8 hours;

[0096] (2) Polyvinyl alcohol is dissolved in water to obtain a polyvinyl alcohol solution;

[0097] (3) mix polyvinyl alcohol solution and soybean protein solution in dissolving machine, and make the mass ratio of polyvinyl alcohol and soybean protein be 70:30, then add concentration and be 10% sodium hydroxide solution and mix uniformly, dissolving machine Stir at 100°C for 4 hours at a speed of 60r / min to obtain a mixed solution of polyvinyl alcoh...

Embodiment 2

[0113] This example provides a blue soybean protein fiber. The difference between this example and Example 1 is that formaldehyde is used instead of glutaraldehyde in the cross-linking color-fixing treatment agent.

Abstract

The invention provides a colored active organic functional cereal fiber, and a preparation method and an application thereof, and relates to the technical field of fibers. The method comprises the following steps: uniformly mixing a plant protein solution, a polyvinyl alcohol solution and a color paste to obtain a spinning dope, spinning the spinning dope to obtain nascent fibers, sequentially carrying out wet heat drawing and dry heat drawing on the nascent fibers to obtain drawn fibers, and finally carrying out crosslinking color-fixation treatment on the drawn fibers to obtain the colored active organic functional cereal fiber. The preparation method alleviates the technical problem of poor color fastness of existing protein fibers, and a textile formed by weaving the colored plant protein fibers prepared through the preparation method has a significantly improved color fastness, still maintains a bright color after being washed multiple times, and can effectively meet consumers' repeated wearing needs.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a preparation method of five-grain colored active organic functional fiber, five-grain colored active organic functional fiber and its application. Background technique [0002] Plant protein fiber is a new type of environmentally friendly textile material, which is composed of plant protein and polyvinyl alcohol. It not only has good mechanical properties, but also can resist acid, alkali and dry heat, and is soft to the touch, moisture-absorbing and sweat-conducting. Excellent performance, and can be biodegradable, will not cause environmental pollution. [0003] In recent years, with the improvement of people's living standards, people's requirements for textiles are getting higher and higher. The existing vegetable protein fiber textiles have poor color fastness. The need for repeated wear. [0004] In view of this, the present invention is proposed. Contents of the invent...
