Embodiment Construction

[0031] Raw material ratio (mass percentage%):

[0032] Tristyrene polyoxyethylene ether sulfonate: 20-25% (eg 20%, 22%, 25%)

[0033] Chelating dispersant: 25-30% (eg 25%, 28%, 30%)

[0034] Lignosulfonate: 10-15% (eg 10%, 12%, 15%)

[0035] Ethylene glycol disuccinate n-octanol diester sodium sulfonate 10-12% (eg 10%, 11%, 12%)

[0036] Ammonia (25% mass concentration): 3 to 5% (example 3%, 4%, 5%)

[0037] Silicone defoamer: 0.5%

[0038] Water: balance.

[0039] Operation process

[0040] Pump in water, add triphenylethylene polyoxyethylene ether sulfonate, chelating dispersant, ethylene glycol disuccinic acid n-octanyl diester sulfonate, lignosulfonate in turn, heat up to 30-40°C, stir Dissolve evenly. Carefully adjust the pH of the solution to 8.0-8.5 (tested with a pH meter) with aqueous ammonia. Turn off stirring, add silicone defoamer, start stirring for 1 minute, turn off stirring for 2 minutes. Repeat 4 times. Filter the discharge.

Abstract

The invention discloses a levelling agent used for environmentally friendly cotton and a preparation method thereof. The levelling agent is composed of tristyryl polyoxyethylene ether sulphate, chelating disperse agent, lignosulfonate, sodium glycol bis-(1-octyl) sulfo succinate, ammonia water, organic silicon defoaming agent and water. The invention controls dye to be uniformly absorbed and dyed; and dye can be prevented from condensation and precipitation even under the condition of low temperature high electrolyte concentration. 'Full addition method' can be adopted, thus greatly simplifying dyeing operation; the dye is ensured to be steadily and uniformly fixed, thus avoiding ununiform fixation; dyeing speck caused by insoluble calcium carbonate when in fixation by soda ash is prevented, meanwhile dyed object has pure colour and lustre, and handfeel is soft; colour yield is not influenced, batch difference can be reduced, dyeing process can be reduced, cost can be reduced, and wet fastness of dyed object can be improved.

Description

Technical field: [0001] The invention relates to a leveling agent for cotton and a preparation method thereof. Background technique: [0002] The formula of the existing leveling agent for cotton is unreasonable, and the working effect is unsatisfactory. Invention content: [0003] The object of the present invention is to provide an environment-friendly cotton leveling agent with reasonable formula and good working effect and a preparation method thereof. [0004] Technical solution of the present invention is: [0005] An environment-friendly cotton leveling agent is characterized in that it consists of the following components by weight percentage: [0006] Tristyrene polyoxyethylene ether sulfonate: 20-25% [0007] Chelating dispersant: 25-30% [0008] Lignosulfonate: 10-15% [0009] Sodium n-octanol diester ethylene glycol disuccinate 10-12% [0010] 25% ammonia water: 3-5% [0011] Silicone defoamer: 0.5% [0012] Water: balance. [0013] The preparation met...
