Problems solved by technology

[0003] At present, due to the extensive use of domestic dyes and the emergence of a large number of new structural fabrics, in the actual production process, the color of the dyed fabric is not bright enough, gray and dark, resulting in a decrease in the grade of fabric products and a decline in competitiveness. In fact, the dyeing depth The higher the color is, the better the light fastness is. When dyeing light colors, the light fastness is often unqualified
However, although the existing organic silicon or non-silicon darkening agents and brightening agents on the market can improve the color of the fabric, the effect of darkening and brightening is poor, and the darkening and reddish light make the fabric smooth and soft. Poor, lack of product stability, still can not achieve satisfactory results, and the color of the fabric will drop significantly after repeated washing, losing efficacy

Embodiment

[0040] The darkening and brightening agent for fabrics provided by the invention comprises the use of amino silicone oil, which is characterized in that N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane function is introduced into the structure of amino silicone oil. group.

[0041] Such as figure 1 As shown, the production method of the darkening and brightening agent for fabrics provided by the invention is to adopt octamethylcyclotetrasiloxane or linear hydroxyl-terminated polydimethylsiloxane and aminoethylaminopropylmethyl dimethyl Oxysilane is polymerized into an amino silicone oil under the action of a catalyst, and then emulsified into an emulsion of a water system under the action of a surfactant, and then a certain proportion of cationic polyurethane resin emulsion or cationic acrylic resin emulsion is added, which is the product of the present invention. The above-mentioned darkening and brightening agent for fabrics. Here, the catalyst is potassium hydroxide. ...

Embodiment 2

[0069] The production method of the darkening and brightening agent described in this example is to use a mixture of methylcyclosiloxane and aminoethylaminopropylmethyldimethoxysilane to polymerize into a kind of amino silicone oil under the action of a catalyst, and then apply it on the surface Under the action of the active agent, it is emulsified into an emulsion of the water system, and then a certain proportion of cationic polyurethane resin emulsion or cationic acrylic resin emulsion is added, which is the darkening and brightening agent for fabrics of the present invention. Here, the catalyst is tetramethylammonium hydroxide.

[0070] The process is as follows:

[0071] The first step: add the mixture of methylcyclosiloxane and aminoethylaminopropylmethyldimethoxysilane into the emulsification reaction kettle, add the catalyst tetramethylammonium hydroxide, stir and raise the temperature to react, after the reaction is completed, add The neutralizing agent carbon dioxi...

Abstract

The invention discloses a brightening agent for fabrics, which comprises the use of amino-silicone oil and is characterized in that N-(beta-aminoethyl)-gamma-aminopropyl methyl dimethoxy silane functional groups are introduced to the structure of the amino-silicone oil. The production method of the brightening agent for the fabrics adopts the polymerization of octamethylcyclotetrasiloxane or the mixture of methyl cyclic siloxane, or linear hydroxy-terminated polydimethylsiloxane and aminoethyl aminopropyl methyl dimethoxy silane for preparing the amino-silicone oil under the action of a catalyst, then the amino-silicone oil is emulsified to emulsion of a water system under the action of a surfactant, and cationic polyurethane emulsion or cationic acrylic resin emulsion with a certain proportion is further added. The technical effects are as follows: the product stability is excellent; the brightening agent has significant brightening role after being used on natural fabrics and synthetic fabrics, the color light level is improved by 4 to 5 levels, and the brightening agent has no emission pollution, thereby being in line with the requirements of environmental protection; and the brightening agent can also improve the smooth and soft hand feel of the fabrics.

Description

technical field [0001] The invention relates to a textile auxiliary agent, in particular to a method for producing a darkening and brightening agent for fabrics and a product thereof. Background technique [0002] With the continuous advent of new textile products, the textile auxiliaries market will also develop rapidly. With the gradual cancellation of textile export quotas after joining the WTO, my country's textile exports will also increase to a certain extent, so the demand for textile auxiliaries will also increase accordingly. As people pay more and more attention to green textiles and environmental ecological protection, environmentally friendly textile auxiliaries have become the main direction of the development of textile auxiliaries today. The International Association for Textile Ecology Research and Inspection has made it clear that textile auxiliaries must not only have the necessary process applicability, application performance and firm performance, but al...
