Description
Technical field
The present invention relates to the textile dyeing and finishing manufacture field, especially relate to desizing agent that a kind of woven fabric dye-bath retreat process uses and preparation method thereof.
Background technology
The dyeing of traditional woven fabric generally is divided into " destarch---dyeing---reduction cleaning " three-steps process and " destarch---dyeing " two-step process.Traditional dyeing is not only wasted time and energy, and energy consumption height, efficient are low.And woven fabric dye-bath retreat method technology is changed into destarch dyeing one-step method with traditional three-step approach or two-step method, be that fabric is not needing draining directly to realize textile dyeing under weak acid or weak basic condition after the destarch, shortened dyeing time greatly, energy efficient has reduced environmental pollution.In woven fabric dye-bath retreat process, the prescription of desizing agent and preparation method realize the guardian technique of woven fabric dye-bath retreat method technology.
In view of this, the inventor designs a kind of novel desizing agent at woven fabric dye-bath retreat process specially, and to have overcome the defective in the conventional art, this case produces thus.
Summary of the invention
The purpose of this invention is to provide desizing agent that a kind of woven fabric dye-bath retreat process uses and preparation method thereof, can realize that the destarch of woven fabric, dyeing carries out with bathing, have energy-saving and emission-reduction and improve the characteristics of dyeing and weaving thing dyeing and finishing efficient.
In order to reach above-mentioned purpose, solution of the present invention is:
The desizing agent that a kind of woven fabric dye-bath retreat process is used, make by following component by weight percentage:
The moon/nonionic refining agent 30%～60%;
Soda ash 10%～30%;
Bleeding agent 10%～20%;
Buffer 1%～5%;
Its surplus is a water.
Described the moon/nonionic refining agent is formed by phosphate and Seconary Alkane Sulphonate Sodium mixed preparing; Wherein, phosphate accounts for 45% of gross weight, and Seconary Alkane Sulphonate Sodium accounts for 55% of gross weight.
Described bleeding agent is a maleic acid di-sec-octyl sodium sulfonate.
Described buffer is potassium dihydrogen phosphate or sodium hydrogen phosphate or the mixture of the two.
The concrete percentage by weight of described component is: the moon/nonionic refining agent 35.6%, soda ash 23.4%, bleeding agent 13.5%, buffer 2%, water 25.5%; Perhaps the moon/nonionic refining agent 50.3%, soda ash 20.4%, bleeding agent 18.6%, buffer 4.3%, water 6.4%.
The acting as of each component during raw material is formed:
One, the moon/nonionic refining agent: be made up of phosphate and Seconary Alkane Sulphonate Sodium, structure is phosphate ROPO (OH)
2, R is natural laruyl alcohol.This material has multiple functions such as good penetration, emulsification, washing decontamination under high temperature, highly basic condition, in linen-cotton and polyester-cotton fabric pre-treatment process, can effectively remove cotton wax, grease and mineral matter and other components, therefore be highly suitable for woven fabric dye-bath retreat method technology.
Two, soda ash Na
2CO
3: can contain intermingle with reaction with the slurry of fabric face, make slurry break away from fabric face, thereby reach the destarch effect.
Three, bleeding agent: be mainly maleic acid di-sec-octyl sodium sulfonate C

2O, pH value is bathed in adjustable water saving, makes water-bath keep weak basic condition, is beneficial to the woven fabric one-bath dyeing.
The preparation method of described desizing agent, its step is as follows:
The soda ash that will account for gross weight 10%～30% earlier adds water and dilutes, and preparation concentration is 5%～10% solution; Then, solution is added in the reactor, be heated to 50 ℃ ± 5 ℃; Add the moon/nonionic refining agent that accounts for gross weight 30%～60% again, stir; Add the bleeding agent that accounts for gross weight 10%～20% again, be cooled to room temperature then; At last, add the buffer that accounts for gross weight 1%～5%, regulate the pH value between 6.8～7.5; After fully mixing, promptly get white or faint yellow emulsion.
The preparation of described bleeding agent: under Catalyzed by p-Toluenesulfonic Acid agent catalysis, carry out esterification in 120-140 ℃ by maleic anhydride and secondary octanol, carry out sulfonation with sodium hydrogensulfite again and make.
Using method: the dyeing machine into cloth of intaking under the normal temperature, and to regulate bath raio be 1: 8, then cloth turned round 2-3 week, returns flowing water to secondary cylinder; Normal temperature adds this product down, and consumption is about the heavy 2%-5% of cloth, and product is fully dissolved, and adds dye vat fast, and is warming up to 85 ℃ with the speed of 1.5 ℃/min, and the destarch process is promptly finished.
After adopting such scheme, desizing agent of the present invention has excellent acid alkalescence in the application of woven fabric dye-bath retreat process can, and have good refining, emulsification, oil removing, remove stupid dirt, remove effect such as various slurries, be the key auxiliary agent of realizing woven fabric dye-bath retreat process.In addition, the in use pollution-free generation of this desizing agent, environmental protection have energy-saving and emission-reduction and the characteristics that improve dyeing and weaving thing dyeing and finishing efficient.Therefore, the present invention has wide economic benefit and social benefit, has a extensive future.
