Problems solved by technology

[0005] The technical problem mainly solved by the present invention: the existing color fixing agent is easy to produce sticking roller and fabric discoloration phenomenon in the color fixing process and finishing process, and has poor water resistance, and is not firmly combined with fabric and dye, which is very important for improving fabric dryness, The defect of poor color fastness to wet rubbing provides a way to improve the affinity between dyes and fabrics through pollen protein, so that it can enhance the affinity of the two based on the formation of van der Waals force and hydrogen bonds between fibers and dyes, Then, pollen protein has high-efficiency and strong oxidation performance, and then it is bonded with peach gum and then compounded with plant leaf wax, wrapped on the surface of the dye, improving the color fastness of the dye, and improving its water resistance through wax hydrophobicity, the present invention First vacuum-dry the tea pollen, crush and sieve, collect the broken pollen particles, then filter it with petroleum ether ultrasonically, collect the filter cake and wash it, mix it with deionized water, adjust the pH, heat and centrifuge, and collect the filtrate After standing and aging, filter, freeze-dry the filter cake to obtain pollen protein, then dry and grind the camellia leaf, mix with ethyl acetate and heat, filter, spin-steam the filtrate until dry to obtain dry camellia leaf wax, and then freeze-dry the peach gum After grinding, homogenize with pollen protein, dry camellia wax, etc. and heat treatment, and finally filter while hot and collect the filtrate, let it stand and cool to prepare a water-resistant high-color-fast color-fixing agent, the color-fixing agent prepared by the present invention The effect of color fastness is good, while improving the water resistance, it can effectively improve the color fastness to dry and wet rubbing of the fabric, and it is not easy to stick to the roller during the production process, so it has a good application prospect

example 1

[0017] First select fresh tea pollen, put it in vacuum drying at 45°C for 3 hours, collect the dried tea pollen and place it in a vibrating ultrafine pulverizer, control the filling rate of the vibration medium to 70%, and the filling rate of the material to 100%. After 20 minutes, collect the crushed pollen particles and pass through a 250-mesh sieve to collect the crushed pollen particles; then mix the above-prepared crushed pollen particles with petroleum ether in a mass ratio of 1:8, place them in a beaker, and vibrate ultrasonically at 200W for 15 minutes Finally, filter and collect the filter cake, wash with deionization for 3 times, then mix the washed filter cake with deionized water at a mass ratio of 1:10, and adjust the pH to 8.5 with a mass fraction of 15% sodium hydroxide solution. , then heated in a water bath at 55°C for 2 hours, then centrifuged at 2500r / min and collected the filtrate, adjusted the pH to 6.0 with glacial acetic acid, left to age for 3 hours, fil...

Abstract

The invention discloses a preparation method of a water-resistant high-color-fast color-fixing agent, which belongs to the technical field of printing and dyeing auxiliaries. In the present invention, the camellia pollen is vacuum-dried first, crushed and sieved, and the broken pollen particles are collected, then ultrasonically oscillated with petroleum ether, filtered, and the filter cake is collected, washed, mixed with deionized water, heated and centrifuged after adjusting the pH, Collect the filtrate and let it stand for aging, then filter, freeze-dry the filter cake to obtain pollen protein, then dry and grind the camellia leaves, mix and heat with ethyl acetate, filter, spin-steam the filtrate until dry to obtain dry camellia wax, and then extract the peach gum After freeze-drying and grinding, it is homogenized with pollen protein, dried camellia wax, etc. and heat-treated. Finally, it is filtered while it is hot and the filtrate is collected. After standing and cooling, a water-resistant high-color-fast color-fixing agent can be prepared. While improving the water resistance of the colorant, it can effectively improve the dry and wet rubbing color fastness of the fabric, and it is not easy to stick to the roller during the production process, so it has a good application prospect.

Description

technical field [0001] The invention discloses a preparation method of a water-resistant high-color-fast color-fixing agent, which belongs to the technical field of printing and dyeing auxiliaries. Background technique [0002] In recent years, with the improvement of people's economic level, the demand for textiles is increasing, and the requirements for textiles are also getting higher and higher, such as requiring more colorful clothing and textile production to meet various standards. Especially after my country's entry into the WTO, the processing requirements for textiles are in line with international standards, the most important of which are the restrictions on formaldehyde content on textiles and the requirements for color fastness. The European Union, the United States, Japan and other countries attempt to use these two indicators to limit the export of Chinese textiles, resulting in technical barriers. [0003] Since many commonly used dye molecules contain wate...
