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] The preparation method of the modified amino organofluorosilicone oil emulsion deepening finishing agent of the present invention has the following steps:

[0038] (1). Preparation of amino organofluorosilicone oil: add 90g of octamethylcyclotetrasiloxane to the first flask, heat up to 90 ℃, and add 10g of N-(β-aminoethyl)-γ-aminopropyl Dimethoxysilane was mixed with 2g of deionized water, stirred well, slowly added dropwise to the above three-necked flask, then added 0.05g of KOH, reacted for 3 hours, and then added 10g of trifluoropropylmethyl Cyclotrisiloxane continues to react for 4 hours; add 0.1g of hexamethyldisiloxane to the above solution, react for 1 hour, reduce the temperature to 60°C, continue the reaction for 20 hours, and obtain a uniform translucent viscous amino group after cooling Organofluorosilicone oil;

[0039] (2). Preparation of triethylamine acrylate: Dissolve 14.4g of acrylic acid in 30g of isopropanol, add it to the second flask, raise the tempera...

Embodiment 2

[0043] This embodiment is the same as embodiment 1, the difference is that the 10g trifluoropropylmethylcyclotrisiloxane described in step (1) uses 12g trifluoropropylmethylcyclotrisiloxane Instead, the modified amino organofluorosilicone oil emulsion deepening finishing agent prepared in this example has the performance test results shown in Table 1.

Embodiment 3

[0045] This embodiment is the same as embodiment 1, the difference is that the 10g N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane described in step (1) uses 12g N -(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane instead, the modified amino organofluorosilicone oil emulsion deepening finishing agent prepared in this example has the performance test results 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 additives, and specifically relates to a modified amino organofluorosilicone oil emulsion deepening 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, air permeability, and skin care and health care effects. It has been widely used. With the continuous expansion of the use of real silk, the quality of silk printing and dyeing has been improved, and the variety of patterns has been increased to meet market demand. However, the existing silk dyeing and printing processes generally use acid dyes, but there are several problems: [0003] (1). The dye uptake rate is low, and the saturation threshold is low, which makes it difficult to process the dark color of silk; [0004] (2). Dyeing with acid dyes in alkaline medium, low fixation rate;...
