Problems solved by technology

[0005] Liu Yue and others used 1,3,5-tris(methyltrifluoropropyl)cyclotrisiloxane and N-β-aminoethyl-γ-aminopropylmethyldimethoxysilane as raw materials to synthesize N-β-aminoethyl-γ-aminopropylmethylsiloxane / trifluoropropylmethylsiloxane copolymer (AFSO), although it has a certain darkening effect on cotton, but the ammonia value of AFSO is relatively low High, easy to cause fiber yellowing (see: Liu Yue, An Qiufeng, Huang Liangxian, Infrared Characterization and Application Performance of Aminoalkyl / Trifluoropropyl Polysiloxane Darkening Agent, Silicone Materials, 2009, 23(5) , 308~311)
[0006] For the special black dyeing of fabrics, it is necessary to use the darkening technology to achieve it. Amino silicone oil has both soft and darkening effects, but the darkening effect on special black dyeing is limited.

Embodiment 1

[0046] Add 10.0Kg amino silicone, 0.5Kg ternary copolymerization silicone, 0.83Kg secondary alcohol polyoxyethylene (6) ether, 1.1Kg octadecyl dimethyl hydroxyethyl quaternary ammonium salt, 0.28Kg paraffin emulsifier to In a 250Kg reactor, heat up to 60°C while stirring, then slowly add 84.79Kg of water preheated at 60°C and 2.5Kg of higher alkyl ketene dimer, and stir well to obtain a mass fraction of 15.2%. Deep agent.

[0047]Take 9Kg of the above-mentioned darkening agent, add it to 91K g of water, and stir to obtain the darkening agent finishing solution. Then, the dyed silk fabric is soaked in the above-mentioned darkening agent finishing solution, dehydrated by centrifugation and dried, and then treated at high temperature (160° C.) for 45 seconds to obtain a real silk fabric with darkening function.

Embodiment 2

[0049] Add 15.0Kg amino silicone, 1.5Kg ternary copolymerization silicone, 1.24Kg secondary alcohol polyoxyethylene (6) ether, 1.65Kg octadecyl dimethyl hydroxyethyl quaternary ammonium salt, 0.41Kg paraffin emulsifier to In a 250Kg reaction kettle, heat up to 65°C while stirring, then slowly add 78.2Kg of water preheated at 65°C and 2.0Kg of higher alkyl ketene dimer, and stir well to obtain a mass fraction of 21.8%. Deep agent.

[0050] Take 6Kg of the above-mentioned darkening agent, add it into 94K g water, and stir to obtain the darkening agent finishing solution. Then, the dyed wool fabric was soaked in the above-mentioned darkening agent finishing solution, dehydrated and dried by centrifugation, and then treated at high temperature (180°C) for 2 minutes to obtain wool fabric with darkening function.

Embodiment 3

[0052] Add 23.0Kg amino silicone, 2.5Kg ternary copolymerization silicone, 1.95Kg secondary alcohol polyoxyethylene (8) ether, 2.6Kg octadecyl dimethyl hydroxyethyl quaternary ammonium salt, 0.65Kg paraffin emulsifier to In a 250Kg reaction kettle, heat up to 65°C while stirring, then slowly add 64.1Kg of water and 5.2Kg of higher alkyl ketene dimer that have been preheated at 65°C successively, and after thorough stirring, the mass fraction is 35.9%. Deep agent.

[0053] Take 5Kg of the above-mentioned darkening agent, add it to 95K g of water, and stir to obtain the darkening agent finishing solution. Then, the dyed polyester fabric was soaked in the above-mentioned darkening agent finishing solution, centrifuged, dehydrated and dried, and then treated at high temperature (190°C) for 2.5 minutes to obtain a polyester fabric with darkening function.

Abstract

The invention discloses a deepening agent and a preparation method thereof, as well as a method for improving the color fastness of dyeing textiles. The deepening agent consists of amino organic silicon, ternary copolymerized organosilicon, alkyl ketene, an emulsifier and water. Deepened textiles finished by the deepening agent have good deep color property and high color fastness. In addition, the preparation method of the deepening agent and a finishing processing method of the textiles are low in production cost, simple to operate and applicable in the field of finishing of dyeing textiles.

Description

technical field [0001] The invention belongs to the technical field of textile chemicals, and in particular relates to a darkening agent, a preparation method thereof and a method for improving the color fastness of dyed textiles. Background technique [0002] In recent years, the requirements for the color depth of textiles have gradually increased with the improvement of people's requirements for the performance of textiles. As a high value-added commodity, textiles often require a high-grade sense of deep color. [0003] At present, there are still some problems in the dark dyeing of textiles, especially the chemical fibers with fine denier or ultrafine denier, or protein fibers with scale structure, it is difficult to obtain dark dyed textile products with high color fastness. In order to improve the dark dyeing of textile products, the following methods are generally adopted: one is to choose dyes with good dyeing properties for fibers, the other is to choose a suitabl...
