Problems solved by technology

[0003] (1). The dye uptake rate is low, and the saturation threshold is low, which makes it difficult to process dark silk;
[0004] (2). Dyeing with acid dyes in alkaline medium, the color fixation rate is low;
[0005] (3). A large amount of salt and alkali will be consumed to produce a large amount of colored and salty polluted wastewater
But described " darkening agent copolymerization emulsion " or " real silk fabric darkening agent copolymerization emulsion " finishing real silk fabric by dipping process, the real silk fabric that obtains through baking is poor in washing resistance and feels rough and has affected the effect of these darkening agents therefore. widely used

Embodiment 1

[0037] A preparation method of a modified aminoorganofluorine silicone oil emulsion darkening finishing agent of the present invention, the steps are as follows:

[0038] (1). Preparation of aminoorganofluorosilicone oil: Add 90g of octamethylcyclotetrasiloxane into the first flask, heat up to 90°C, and add 10g of N-(β-aminoethyl)-γ-aminopropyl Dimethoxysilane was mixed with 2g of deionized water, stirred evenly, and slowly added dropwise to the above-mentioned three-necked flask, then 0.05g of KOH was added, reacted for 3 hours, and then added 10g of trifluoropropylmethyl Continue to react cyclotrisiloxane for 4 hours; add 0.1 g of hexamethyldisiloxane to the above solution, react for 1 hour, cool down to 60°C, continue to react for 20 hours, and obtain uniform translucent viscous amino Organic fluorosilicone oil;

[0039] (2). Prepare triethylamine acrylate: dissolve 14.4g of acrylic acid in 30g of isopropanol, add it to the second flask, raise the temperature to 40°C, then...

Embodiment 2

[0043] The present embodiment is the same as Example 1, and its difference is that the trifluoropropylmethylcyclotrisiloxane of 10g described in step (1) uses the trifluoropropylmethylcyclotrisiloxane of 12g Instead, the performance testing results of the modified aminoorganofluorosilicone oil emulsion darkening finishing agent prepared in this example are shown in Table 1.

Embodiment 3

[0045] The present embodiment is the same as Example 1, the difference is that 10g of N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane described in step (1) is used with 12g N -(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane instead, the modified aminoorganofluorosilicone oil emulsion deepening finishing agent prepared in this example, its performance test results are shown in Table 1 Show.

Abstract

The invention discloses a modified amino organic fluorosilicone oil emulsion color-deepening finishing agent. The color-deepening finishing agent is characterized by being prepared from, by mass, 50%-95% of octamethylcyclotetrasiloxane, 1%-30% of 1,3,5-trimethyltris-1,5-(3,3-trifluoropropyl)-cyclotrisiloxane, 1%-20% of N-(beta-aminoethyl)-gamma-aminopropyl methyl dimethoxy silicane, 0.01%-0.1% of an end capping agent, 0.01%-0.1% of a high-alkalinity catalyst, 0.1%-2% of an emulsifying agent and the balance deionized water. The modified amino organic fluorosilicone oil emulsion color-deepening finishing agent has the following structural formula (please see the formula in the description), wherein X ranges from 10 to 100, Y ranges from 80 to 1,000, Z ranges from 7 to 70, and X, Y and Z are all integers. A preparation method has the advantages that the raw materials are easy to obtain, and operation is convenient. The color-deepening finishing agent prepared through the method is used for finishing a real silk fabric, the finished real silk fabric has the excellent color fixing property and washing resistance, the reflected light amount on the fiber surface is decreased, and the color-deepening effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a modified amino organic fluorine silicone oil emulsion darkening finishing agent and a preparation method thereof. Background technique [0002] Silk is a high-quality natural fabric, mainly composed of protein fibers, with thick and plump, excellent elasticity, good moisture absorption, breathability, and skin care and health care effects, and has been widely used. With the continuous expansion of the use of silk, the quality of silk printing and dyeing should be improved, and the varieties of designs and colors should be increased to meet the market demand. However, the existing silk dyeing and printing processes generally use acid dyes, but there are the following problems: [0003] (1). The dye uptake rate is low, and the saturation threshold is low, which makes it difficult to process dark silk; [0004] (2). Dyeing with acid dyes in alkaline mediu...
