Embodiment 1

[0035] In a 2000ml four-necked flask, 740g of octamethylcyclotetrasiloxane (D 4 ), 76.4g (0.4mol) dimethylaminopropylmethyldimethoxysilane and basic catalyst were mixed and heated and stirred, 7.2g of water was added dropwise, heated to 110°C for 3h, cooled to 78°C, added 222g To isopropanol, add 22g (0.2mol) 3-chloro-1,2-propanediol dropwise, react at 78-80°C for 2 hours, cool down to 50°C, add 12g (0.2mol) acetic acid, and put the mixture at 80°C The isopropanol was distilled off to obtain a turbid, highly viscous liquid sample 1, which was described by the following general statistical formula:

[0036]

Embodiment 2

[0038] In a 2000ml four-necked flask, mix 44g (0.2mol) 3-[(2,3)-glycidoxy]propylmethyldimethoxysilane and 20g (0.2mol) methylpiperazine at room temperature , avoid light and isolate the air reaction for 24h, add 740g octamethylcyclotetrasiloxane (D 4 ) and the basic catalyst were mixed and heated and stirred, 3.6g of water was added dropwise, heated to 110°C for 3h, cooled to 78°C, 222g of isopropanol was added, 25.2g (0.2mol) of dimethyl sulfate was added dropwise, at 78 ~80 DEG C slight boil reaction 2h, cool down to 50 DEG C, add 12g (0.2mol) acetic acid, this mixture is distilled off isopropanol at 80 DEG C, obtain cloudy high-viscosity sample 2, it is described by the following statistical general formula:

[0039]

Embodiment 3

[0041] In a 2000ml four-necked flask, mix 220g (1mol) of 3-[(2,3)-glycidoxy]propylmethyldimethoxysilane and 74g (1mol) of diethylamine at room temperature and keep away from light Isolate the air and react for 24 hours, add 740g linear body (WS-62M) and basic catalyst to mix and heat and stir, add 18g of water dropwise, heat to 110°C for 3h, cool down to 78°C, add 222g of isopropanol, add dropwise 100.8 g (0.8mol) of dimethyl sulfate, react at 78-80°C for 2 hours, cool down to 50°C, add 12g (0.2mol) of acetic acid, distill the mixture at 80°C to distill isopropanol to obtain a cloudy high-viscosity sample 3, which is described by the following general statistical formula:

Abstract

The invention provides a polysiloxane softening agent with color fixing property. The softening agent comprises polysiloxane with the general formula structure DnM, wherein D is equal to SiY2O2 / 2, M is equal to QSiYO2 / 2, and Y represents the same or different groups selected from the following substances: alky with 1-30 carbon atoms, aryl or alkaryl, preferably, Y is methyl or phenyl, and more preferably, Y is methyl, and Q represents the same or different organic groups with quaternary ammonium salt functional groups. The side chain of the polysiloxane softening agent with color fixing property is polysiloxane with quaternary ammonium salt and (or) tertiary amine acid salt, the quaternary ammonium salt and (or) tertiary amine acid salt of the side chain have (has) color fixing function, the polysiloxane of the main chain is of the softening agent with excellent performance, the polysiloxane has good hand feel, better wet and dry rub strength, and better soaping fastness; and a formed composition is stable during storage. The invention provides the softening agent with color fixing property for textiles and nonwoven fabrics.

Description

technical field [0001] The invention relates to a polysiloxane softener with color-fixing performance and a preparation method thereof, belonging to the technical field of textile auxiliaries. Background technique [0002] In order to make textiles and clothing feel soft and colorful, it is necessary to add color-fixing agents and softeners in the process of textile production and household daily washing of clothing. In textile production, two functions can be achieved in the color fixing process and the softening process respectively; but in daily household laundry washing, two purposes need to be achieved through one wash, so softeners with color fixing properties have emerged as the times require. Softeners with color-fixing properties can not only be applied to daily laundry washing formulations, but also to textile production, so that the color-fixing and softening process can replace the color-fixing process and softening process, thereby achieving the goal of high eff...
