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, lignin sulfonate 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 wetfastness 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...
