Method for preparing functional protein fiber

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...

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
