Problems solved by technology

[0005] The existing finishing methods have a certain decontamination effect, but there is a problem of insufficient household washing times; this is because the chemical finishing agent is difficult to react with the fiber, and the chemical finishing agent only covers the surface of the fiber. Although the addition...

Embodiment 1

[0038] The preparation of the pre-condensed aqueous solution: 20Kg acrylic acid, 15Kg N-vinyl-2-pyrrolidone and 65Kg water were added to the reaction kettle, heated to 60℃ while stirring, and then 1.75Kg potassium persulfate was added and reacted for 5 hours. An acrylic acid / N-vinyl-2-pyrrolidone pre-condensed aqueous solution with a mass concentration of 35% was obtained.

[0039] Attached figure 1 Is the infrared spectrum of the pre-shrinked body in the aqueous solution of the above-mentioned pre-shrinked body. figure 1 It can be seen that the pre-condensate is a polyacrylic acid / pyrrolidone polymer.

Embodiment 2

[0041] The preparation of the pre-condensed aqueous solution: 15Kg of methacrylic acid, 19Kg of acrylamide and 66Kg of water were added to the reactor, and the temperature was raised to 70℃ while stirring, and then 1.70Kg of potassium persulfate was added and reacted for 4 hours to obtain the mass concentration It is a 34% methacrylic acid / acrylamide pre-condensed aqueous solution.

Embodiment 3

[0043] Preparation of pre-condensed aqueous solution: 15Kg acrylic acid, 15Kg N-vinyl-2-pyrrolidone, 10Kg acrylamide and 60Kg water were added to the reaction kettle, heated to 80°C while stirring, and then 2.40Kg potassium persulfate was added, reaction 3 After hours, an acrylic acid / N-vinyl-2-pyrrolidone / acrylamide pre-condensed aqueous solution with a mass concentration of 40% was prepared.

[0044] Attached figure 2 Is the infrared spectrum of the pre-shrinked body in the aqueous solution of the above-mentioned pre-shrinked body. figure 2 It can be seen that the pre-condensate is a polyacrylic acid / pyrrolidone / acrylamide polymer.

Abstract

The invention discloses a method for preparing functional protein fiber. The method comprises the following steps: firstly, dipping the fiber into a finishing solution; then dewatering and drying the dipped fiber; finally baking or microwave-processing the dried fiber to obtain the functional fiber, wherein the finishing solution is prepared from the following four ingredients in percentage by weight: 5-15 percent of preshrinking aqueous solution, 5-20 percent of vinyl monomer, 0.15-1.6 percent of initiator and the rest of water. The functional protein fiber prepared by the method has a good soil release performance and good washing fastness and the hand feeling of subsequent fabrics is not influenced. The processing method has low production cost and stronger operability and is suitable for industrial application.

Description

Technical field [0001] The invention relates to a fiber finishing technology, in particular to a method for preparing functional protein fibers. Background technique [0002] Textile antifouling is to reduce or reduce the accumulation of dirt on textiles, and easy decontamination is to increase or increase the removal rate of dirt that has accumulated on textiles. Generally speaking, the antifouling property can be obtained by changing the fabric structure, fiber surface state and fiber surface performance. The former two are beneficial to reduce or reduce the accumulation of dirt, especially solid dirt; the latter can reduce or reduce oily dirt Is advantageous. Due to the diverse characteristics of textiles, the first two are often difficult to change. Therefore, people often use chemical finishing to change the surface properties of fibers to improve the oil resistance of textiles, so that the fabrics are not easily stained, especially oily stains. Performance. [0003] The st...
