Problems solved by technology

[0003] The patent of invention with the application number of prior art 200810060886.3 discloses a fiber darkening agent emulsion and its preparation method. Body, etc. are prepared by emulsion polymerization process. Since the initiator used in the synthesis is N-methylol acrylamide, it will remain in the fabric, which is not good for the human body, and the texture and appearance of the fabric treated with this darkening agent will become worse. Therefore, the use of this darkening emulsion is limited
[0004] The invention patent with the application number of prior art 201010288531.7 discloses the darkening and brightening finishing agent for dyed cotton fabrics and its preparation method, but this technology is mainly aimed at the darkening and brightening treatment of dyed cotton fabrics. The quaternary ammonium salt type cationic emulsifier has a good effect on darkening and brightening dyed cotton fabrics, but the darkening effect on polyester fabrics is not ideal, and its use is also limited

Embodiment 1

[0035] ① Under the condition of nitrogen protection, add 12 grams of dodecyl dimethyl benzyl ammonium bromide in a 500 mL four-necked flask, then add 10 grams of TX-50 (solid), 232 grams of deionized water and 1 1 g of ethylene glycol, turn on the stirrer at a speed of 300 rpm to dissolve TX-50 in the solution, and finally add a catalyst aqueous solution in which 1 g of sodium hydroxide is dissolved in 50 g of deionized water, and turn on the constant temperature water bath to adjust to 35°C.

[0036] ②Put 90 grams of methyltrimethoxysilane and 10 grams of γ-(2,3-epoxypropoxy)propyltrimethoxysilane in a 250mL beaker, mix the two liquids evenly, add the dropping funnel, and then use the dropping liquid The prepared reaction solution was added dropwise into the four-neck flask through the funnel. Control the dripping speed, and the feeding time is controlled at about 2 hours. After the addition, adjust the reaction to the desired temperature of 50°C, continue the reaction for 3...

Embodiment 2

[0039]① Under the condition of nitrogen protection, add 15 grams of dodecyltrimethylammonium bromide to a 500 mL four-necked flask, then add 12 grams of TX-40 (solid), 232 grams of deionized water and 1 gram of propylene glycol , turn on the stirrer at a speed of 300rpm to dissolve TX-40 in the solution, and finally add an aqueous catalyst solution in which 1 gram of potassium hydroxide is dissolved in 50 grams of deionized water, and turn on the constant temperature water bath to adjust to 35°C.

[0040] ②Add 120 grams of methyltriethoxysilane and 12 grams of γ-(2,3-epoxypropoxy)propylethylmethoxysilane into a 250mL beaker, mix the two liquids evenly, add them to the dropping funnel, and then use The dropping funnel was used to drop the prepared reaction solution into the four-neck flask. Control the dripping speed, and the feeding time is controlled at about 2 hours. After the addition, adjust the reaction to the required temperature of 60°C, continue the reaction for 3 hou...

Embodiment 3

[0043] ① Under the condition of nitrogen protection, add 20 grams of tetradecyl dimethyl benzyl ammonium bromide in a 500 mL four-necked flask, then add 20 grams of AEO-50 (solid) and 170 grams of deionized water and 2 gram of ethylene glycol, turn on the stirrer, and the rotating speed is 300rpm, so that AEO-50 is dissolved in the solution, and finally add the catalyst aqueous solution in which 1.5 grams of tetramethylammonium hydroxide is dissolved in 50 grams of deionized water, and turn on the constant temperature water bath to adjust to 35 ℃.

Abstract

The invention discloses a terylene fabric deepening agent copolymer emulsion and preparation method thereof. Organic silsesquioxane is prepared, epoxy chloro alkyl compound of amino silicone oil is modified, and then the organic silsesquioxane and modified epoxy chloro alkyl compound of amino silicone oil are compound. The organic silsesquioxane with smaller molecular weight and particle size is prepared by using the emulsion polymerisation technology according to the invention, and the silicon content in the object is high, and the silicon one of the main component of the deepening agent, and the preparation method is environmental protection without pollution, and the epoxy chloro alkyl compound of amino silicone oil containing double-amino with suitable molecular weight is appropriately modified, and a epoxide group is introduced, and after the fabric is processed, the hydrophility keeps unchangeable. The invention has an obvious color increasing effect, and after the fabric is treated by the deepening agent, no residual harmful substances are on the fabric surface, so the product belongs to the green environmental protection finishing agent.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries, and specifically relates to a polyester fabric darkening agent copolymerized emulsion and a preparation method thereof. Background technique [0002] In the current textile market, polyester imitation silk products are incomparable to other fabrics due to their excellent properties such as resilience, washability, dimensional stability and wrinkle resistance, and have good fastness to mildew, moth and dyeing. , so it is more and more popular with consumers, but it is inferior to real silk in terms of fabric color development, color depth and vividness. Especially in recent years, the development of fine-denier polyester fabrics has made the problem of dyeing depth more prominent. , especially in the fact that the fabric is dark but not dark, black is not black, and some black filament fabrics give people a white visual effect. Some people have increased the amount of dye to no avail. On the...
