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 of a crosslinking agent can Improve the combination fastness of chemical finishing agent and fiber, and improve the washing resistance, but it will cause the textiles to feel hard, especially based on soft silk fibers, wool fibers and other protein fibers, the hard feeling will bring the added value of textiles decline

Embodiment 1

[0038] Preparation of pre-condensed aqueous solution: Add 20Kg of acrylic acid, 15Kg of N-vinyl-2-pyrrolidone and 65Kg of water into the reaction kettle, heat up to 60°C while stirring, then add 1.75Kg of potassium persulfate, and react for 5 hours to prepare An aqueous solution of acrylic acid / N-vinyl-2-pyrrolidone precondensate with a mass concentration of 35% was obtained.

[0039] attached figure 1 It is the infrared spectrogram of the pre-shrinkage body in the above-mentioned pre-shrinkage body aqueous solution, by the attached figure 1 It can be seen that the pre-condensation body is a polyacrylic acid / pyrrolidone polymer.

Embodiment 2

[0041] Preparation of pre-condensed aqueous solution: Add 15Kg of methacrylic acid, 19Kg of acrylamide and 66Kg of water into the reaction kettle, raise the temperature to 70°C while stirring, then add 1.70Kg of potassium persulfate, and react for 4 hours to obtain the mass concentration It is a 34% aqueous solution of methacrylic acid / acrylamide precondensate.

Embodiment 3

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

[0044] attached figure 2 It is the infrared spectrogram of the pre-shrinkage body in the above-mentioned pre-shrinkage body aqueous solution, by the attached figure 2 It can be seen that the pre-condensation body 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 preparation method of 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 improve the removal rate of dirt that has accumulated on textiles. Generally speaking, anti-fouling properties can be obtained by changing the fabric structure, fiber surface state and fiber surface properties. The former two are beneficial to reducing or reducing the accumulation of dirt, especially solid dirt; the latter is beneficial to reducing or reducing oily dirt. is advantageous. Due to the diversity of textiles, the first two are often difficult to change, so people often use chemical finishing to change the surface properties of fibers to improve the oil resistance of textiles, so that the fabric is not easy to be stained, especially oily dirt is not easy to be stained....
