Problems solved by technology

[0003] The currently popular color-fixing agent based on copolymers of dimethyl diallyl ammonium chloride and diallylamine can only improve the fastness to washing and dry rubbing, but has no effect on the fastness to wet rubbing. In order to improve the wet rubbing fastness of dyed fabrics; in addition, polyurethane wet rubbing fastness enhancers are mainly used at present, but such wet rubbing fastness enhancers generally have poor stability and are prone to demulsification and failure, so they cannot be used with Problems such as the same solubility of silicone oil

Embodiment 1

[0016] In a four-necked flask with a stirring cooling device, add 1 mol of perfluorooctyl alcohol, add 0.1 mol of triethylamine, and dropwise add acryloyl chloride with the same molar weight as perfluorooctyl alcohol from the separatory funnel, and the rate of addition makes the reaction temperature Keep the temperature below 20°C. After adding acryloyl chloride dropwise, react at a temperature below 20°C for 60 minutes to obtain a light-colored liquid, that is, allyl perfluorooctyl ether, which is ready for use.

[0017] Take by weighing 55 parts by weight of dimethyl diallyl ammonium chloride, 10 parts by weight of diallylamine hydrochloride, 2 parts by weight of allyl perfluorooctyl ether, and 32.5 parts by weight of deionized water are added to the In a four-necked flask with a stirring and heating device, heat up to 80-90°C and keep stirring for 30 minutes, add 5 parts by weight of ammonium persulfate solution with a concentration of 10%, and keep it at 80-90°C for 120 min...

Embodiment 2

[0019] In a four-necked flask with stirring heating and a water separator device, add 1mol perfluorooctyl alcohol, 0.1mol p-toluenesulfonic acid, 0.01mol hydroquinone, and acrylic acid of equal molar weight with perfluorooctyl alcohol, and heat up to 160~180℃, the calculated time from the water in the water separator is about 2~3hrs, until there is no more water in the water separator, stop heating, continue to stir to room temperature, and obtain light-colored perfluorooctyl alcohol acrylate, which is ready for use .

[0020] Take by weighing 60 parts by weight of dimethyl diallyl ammonium chloride, 15 parts by weight of diallyl sulfate, 4 parts by weight of perfluorooctyl alcohol acrylate, and 20 parts by weight of deionized water, add to the tank with stirring and heating In the four-necked flask of the device, stir and heat to 80-90°C, keep warm for 60min, add dropwise 10 parts by weight of sodium persulfate solution with a concentration of 10%, and initiate polymerization...

Embodiment 3

[0022] In a four-necked flask with stirring heating and a water separator device, add 1mol perfluorooctyl alcohol, 0.1mol p-toluenesulfonic acid, 0.01mol hydroquinone, and acrylic acid of equal molar weight with perfluorooctyl alcohol, and heat up to 160~180℃, the calculated time from the water in the water separator is about 2~3hrs, until there is no more water in the water separator, stop heating, continue to stir to room temperature, and obtain light-colored perfluorooctyl alcohol acrylate, which is ready for use .

[0023] Take by weighing 40 parts by weight of dimethyl diallyl ammonium chloride, 5 parts by weight of diallyl sulfate, 1 part by weight of perfluorooctyl acrylate, and 53 parts by weight of deionized water, and add to the In the four-necked flask of the device, stir and heat to 80-90°C, keep warm for 60min, add dropwise 10 parts by weight of sodium persulfate solution with a concentration of 10%, and initiate polymerization. After dropping the sodium persulfat...

Abstract

The invention discloses a fluorine-containing color fixing agent and a preparation method thereof. It consists of the following components in percentage by weight: 40-60% dimethyl diallyl ammonium chloride, 5-25% diallylamine Salt, 1-5% allyl perfluorooctyl ether or ester, 0.5-1% peroxide and the remainder of deionized water; the fluorine-containing color fixing agent of the present invention is yellow and sticky, compared with the existing Color agent, the color fixing agent of the present invention has better stability and can be dissolved with various finishing agents such as silicone oil; and the fabric fastness to washing, dry wiping, wet wiping and sunlight has been significantly improved. The preparation process of the fluorine-containing color-fixing agent of the present invention is simple and convenient, and provides a choice of color-fixing agent with better performance.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries and relates to a color-fixing agent, in particular to a fluorine-containing color-fixing agent and a preparation method thereof. Background technique [0002] Fixing agent is one of the important auxiliary agents in the printing and dyeing industry. It can improve the color fastness of dyes on fabrics to wet treatment. It can form insoluble colored matter with dyes on fabrics to improve the color fastness to washing and perspiration, and sometimes to improve its light fastness. Therefore, when dyeing cellulose fiber fabrics, when dyeing dark colors (dye concentration > 1%), it must be fixed to obtain customer-approved fastness indicators such as washing, dry rubbing, and wet rubbing. [0003] The currently popular color-fixing agent based on copolymers of dimethyl diallyl ammonium chloride and diallylamine can only improve the fastness to washing and dry rubbing, but has no effect on the fas...
