example 1

[0024] In parts by weight, take 20 parts of urethane acrylate, 10 parts of perfluoroundecyl acrylate, 10 parts of trifluoroethyl methacrylate, 10 parts of tetrahydrofuran acrylate, and pour them into the mixing machine at 300r Stir and mix for 45 minutes at a speed of 1 / min, and discharge the material to obtain an organic resin. Then, in parts by weight, take 30 parts of ethyl orthosilicate and 80 parts of a 60% ethanol solution by mass. First, pour the ethanol solution into a three-necked flask. Move the three-necked flask into a digital speed-measuring thermostatic magnetic stirrer, and adjust the pH of the ethanol solution to 2.0 with a mass fraction of 6-8% hydrochloric acid at a temperature of 45°C and a rotational speed of 300r / min. After the pH adjustment is over, Under constant temperature stirring, add ethyl orthosilicate to the three-necked flask through a dropping funnel at a rate of 3mL / min. After the addition of ethyl orthosilicate is finished, continue constant tem...

Abstract

The invention discloses a fabric dyeing deepening agent and a preparation method thereof, and belongs to the technical field of preparation of textile auxiliaries. The fabric dyeing deepening agent is prepared through steps as follows: polyurethane acrylate, perfluoro undecyl acrylate, trifluoroethyl methacrylate and tetrahydrofurfuryl acrylate are mixed, and organic resin is obtained; then pH of an ethanol solution is adjusted with hydrochloric acid and the ethanol solution is stirred with tetraethoxysilane for hydrolysis, pH is adjusted with ammonium hydroxide, silica sol is obtained, left to stand for aging and modified with a silane coupling agent, and modified gel is obtained; the organic resin, petroleum resin and a photoinitiator are mixed and then mixed and dispersed with the modified gel, discharging and packaging are performed finally, and the fabric dyeing deepening agent is obtained. The fabric dyeing deepening agent has a better deepening effect, the fabric subjected to deepening treatment has higher color fastness and better mechanical strength, and service performance of the fabric is effectively improved.

Description

Technical field [0001] The invention discloses a fabric dyeing deepening agent and a preparation method thereof, and belongs to the technical field of textile auxiliary preparation. Background technique [0002] In recent years, the color depth requirements of textiles have gradually increased with the improvement of people's requirements for the wearability of textiles. As a high value-added product, textiles often require a high-end sense of deep color. [0003] At present, there are still some problems in the dark dyeing process of textiles, especially for fine denier or ultrafine denier chemical fibers, or protein fibers with a scaly structure, it is difficult to obtain dark dyed textile products with high color fastness. In order to improve the dark dyeing of textile products, the following methods are generally adopted: one is to choose dyes with good dye uptake to the fiber, the other is to choose a suitable dyeing process or dyeing method, and the third is to choose a deep...
