Problems solved by technology

At present, silicone emulsion is mainly used to prepare denim brightener in the market. Due to the single formula, it has obvious defects in hand feel and gloss, and it needs 50-55 ℃ water temperature to dilute when used.
As the market has higher and higher requirements for denim brighteners, it is difficult for denim brighteners prepared from a single silicone oil emulsion to meet market requirements
Through the search of the prior art, there are few reports of denim brighteners that can obtain perfect application effects

[0022] In parts by weight, put 19 parts of TMN-6 and 1 part of TMN-3 into the reaction tank, control the temperature in the tank at 50°C, control the speed at 100r / min, and stir for 10 minutes. Put 30 parts of PMX-200 into the reaction tank, control the speed at 1000r / min, and stir for 10min. Then 50 parts of deionized water was slowly added into the reaction kettle while stirring. After adding water, continue to stir at high speed for 30 minutes to obtain milky white PMX-30.

[0023] (2) Preparation of 730:

[0024] In parts by weight, 6 parts of 1308 and 4 parts of 1305 were added into the tank, the temperature inside the tank was controlled at 60°C, and the rotation speed was controlled at 50 r / min. Add 30 parts of ternary copolymerization block silicone oil (897) into the reaction tank, control the rotation speed at 120r / min, and stir for 20min. Then add 0.1...

Embodiment 2

[0028] A method for preparing an all-purpose brightener, comprising the steps of:

[0029] (1) Preparation of PMX-30:

[0030] According to parts by weight, 10 parts of TMN-6 and 2 parts of TMN-3 were stirred and reacted at 45°C for 15 minutes, and the speed was controlled at 120r / min; then 25 parts of PMX-200 were put into the reaction for 15 minutes, and the speed was controlled at 1200r / min; Slowly add 45 parts of deionized water to the reaction system while stirring; after adding the water, continue to stir at high speed (1200r / min) for 25 minutes to prepare milky white PMX-30.

[0031] Both TMN-6 and TMN-3 are emulsifiers; the PMX-200 is simethicone with a viscosity of 350cs.

[0032] (2) Preparation of 730:

[0033] In parts by weight, 2 parts of isotridecyl alcohol polyoxyethylene ether 1308 and 6 parts of isomeric tridecyl alcohol polyoxyethylene ether 1305 were stirred at 55°C for 10 minutes, the speed was controlled at 40r / min, and 40 parts of block silicone oil 89...

Embodiment 3

[0037] A method for preparing an all-purpose brightener, comprising the steps of:

[0038] (1) Preparation of PMX-30:

[0039] According to parts by weight, 20 parts of TMN-6 and 0.5 parts of TMN-3 were stirred and reacted at 55°C for 5 minutes, and the speed was controlled at 120r / min; then 35 parts of PMX-200 were stirred and reacted for 5 minutes, and the speed was controlled at 1200r / min; Slowly add 55 parts of deionized water to the reaction system while stirring; after adding the water, continue to stir at high speed (1200r / min) for 35 minutes to obtain milky white PMX-30.

[0040] Both TMN-6 and TMN-3 are emulsifiers; the PMX-200 is simethicone with a viscosity of 350cs.

[0041] (2) Preparation of 730:

[0042]In parts by weight, 10 parts of isotridecyl alcohol polyoxyethylene ether 1308 and 2 parts of isomeric tridecyl alcohol polyoxyethylene ether 1305 were stirred at 65 ° C for 10 minutes, and the speed was controlled at 60 r / min. 25 parts of block silicone oil 89...

Abstract

The invention relates to an all-around brightener for denim fabric as well as a preparation method and application of the all-around brightener. The all-around brightener is prepared from the following components and content: 45 to 55 parts of dimethyl silicone oil emulsion PMX-30, 15 to 25 parts of block silicone emulsion 730, 5 to 15 parts of glycerol GY95, 5 to 15 parts of water-based wax emulsion E770 and 5 to 15 parts of deionized water. The all-around brightener for the denim fabric is prepared by uniformly stirring raw materials, heating, filtering with a filter screen and discharging.Compared with the prior art, the all-around brightener provided by the invention is fluffier, softer and slipperier, darker and clearer in luster, and does not stick to hands after drying. The denim fabric treated by the all-around brightener has higher elasticity and tensile strength; in addition, the all-around brightener can be diluted with normal temperature water before being used, so the operation is simpler and more energy-saving.

Description

technical field [0001] The invention relates to a novel brightener and a preparation method thereof, in particular to an all-purpose brightener for denim fabrics and a preparation method thereof. Background technique [0002] Denim brighteners are mainly used in yarn finishing and textile denim finishing agents in the textile industry. Jeans treated with denim brighteners can produce high gloss, deeper and more vivid colors, as well as higher elasticity and tensile strength. The application of denim brightener in finishing is mainly as an important component of textile finishing agent, the purpose is to give textiles an excellent soft feel, better smoothness and gloss. [0003] Denim brightener is a special reactive polymer, mainly used for yarn finishing and textile denim finishing. Currently on the market, silicone emulsion is mainly used to prepare denim brightener. Due to the single formula, it has obvious defects in hand feeling and gloss, and it needs 50-55°C water t...
