Technical Field

The invention relates to the field of fine chemical engineering, in particular to the technical field of spinning and weaving. In particular to a polyester high stretch yarn detergent and a preparation method thereof

Background

In the prior art, oil removal and decontamination are carried out by adopting a method of cleaning by using an organic solvent, a hot alkali solution and a surfactant solution. Organic solvent methods are divided into three categories: one uses halogenated hydrocarbon as active substance, but the halogenated hydrocarbon has toxicity and pollutes the environment, especially causes very serious damage to the ozone layer, and is not environment-friendly; the other type uses stone hydrocarbon as active matter, such as kerosene as main active matter, which wastes petroleum resources and pollutes environment; the other type of the detergent is mainly alkali, can remove grease and dirt on metal, has strong corrosivity, is easy to damage the metal surface, and has unsatisfactory decontamination effect, and the three types of the detergents can not achieve good decontamination effect.

With the increase of chemical fiber filaments produced in China every year, the subsequent processing amount is increased, and due to the fact that machines are different in old and new and the abrasion condition is aggravated, oil pollution is caused to the filaments, the quality and the grade of products are further influenced, and the removal of oil dirt on the products becomes a problem which needs to be solved by manufacturers in the chemical fiber industry in China urgently. The original detergent cannot meet the increasing requirements in the aspects of effect and environmental protection, and the emergence of a new type high stretch yarn detergent is urgently needed.

Through investigation and research, the following results are found: the selection of detergent products of the polyester high-stretch yarns, the oxidation resistance and the compatibility of chemical fiber yarns, the decontamination characteristic and the washing effect of the detergent for the polyester high-stretch yarns and the like are important factors influencing the selection of the detergent for the polyester high-stretch yarns. However, in the prior art, the polyester high-stretch yarn detergent is often single-sided in emphasis on the stain removal performance, the antistatic performance or the cleaning performance. The detergent for polyester high stretch yarn has large selectivity fluctuation, sometimes the product has incompatibility phenomenon, and the actual use stability is poor.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the defects and shortcomings in the prior art, the invention aims to provide the polyester high-stretch yarn detergent and the preparation method thereof.

The detergent for polyester high stretch yarn is developed through the following more critical 3 influencing factors on the premise of meeting the requirement of environmental protection; (1) under the high requirement of strict environmental protection, the original detergent which has good decontamination effect, is easy to decompose, has no pollution and is easy to clean is developed; (2) the fabric has good washing performance on cotton yarn or grey cloth which takes terylene as main raw material, (3) the fabric has corrosivity to elastic fiber, the current market has little attention to the corrosion problem of the elastic fiber, and the fabric mainly shows two aspects: corrosiveness at the time of use and corrosiveness after washing of the detergent.

The technical scheme adopted by the invention is as follows:

the detergent for the polyester high stretch yarns comprises base oil, an emulsifier, a solubilizer, a preservative, a dispersant, a bactericide and an antistatic agent, wherein the content of the base oil accounts for 90-92% of the total mass of the detergent for the polyester high stretch yarns; the content of the emulsifier is 8-10% of the total mass of the polyester high stretch yarn detergent; the content of the solubilizer is 0.1-2% of the total mass of the polyester high stretch yarn detergent; the content of the preservative is 0.01-0.2% of the total mass of the polyester high stretch yarn detergent; the content of the dispersant is 0.2 to 2 percent of the polyester high stretch yarn detergent; the content of the bactericide is 0.08-1% of the total mass of the polyester high stretch yarn detergent; the content of the antistatic agent is 0.08-1% of the total mass of the polyester high stretch yarn detergent.

Further, the base oil is secondary hydrogenation industrial white oil. Selecting kinematic viscosity of 5.0-6.0mm²The secondary hydrogenation industrial white oil between/s is used as base oil, can meet the use requirement of the polyester high stretch yarn detergent, can reduce the pollution to the environment, and has low viscosity, good fluidity and compatibility, thereby playing a good decontamination effect.

Further, the emulsifier is any one of fatty alcohol-polyoxyethylene ether, fatty alcohol-polyoxyethylene ether and lauryl alcohol-polyoxyethylene ether or a composition of two of the fatty alcohol-polyoxyethylene ether, the fatty alcohol-polyoxyethylene ether and the lauryl alcohol-polyoxyethylene ether in any proportion.

Preferably, the emulsifier is fatty alcohol-polyoxyethylene ether, and is obtained by chemical reaction of fatty alcohol and polyoxyethylene ether. Fatty alcohol-polyoxyethylene ether is the most important nonionic surfactant, is an oil-soluble emulsifier, can enhance the solubility of substances in organic solvents, and ether bonds in molecules are not easily damaged by acid and alkali, so that the stability is high, the water solubility is good, the electrolyte resistance is high, the biodegradation is easy, and the foam is small. The fatty alcohol-polyoxyethylene ether is colorless liquid or wax, and the length of the carbon chain, the addition number and the distribution of the ethylene oxide have great influence on the physical and chemical properties and the application performance of the product. The cloud point, relative density, viscosity and the like of the fatty alcohol-polyoxyethylene ether increase with the increase of the addition number of the ethylene oxide, but the surface activity such as detergency, foamability, wetting and dispersing power of the fatty alcohol-polyoxyethylene ether begins to increase with the increase of the burning addition number of the ethylene oxide, and after the surface activity reaches the maximum value, the addition number of the ethylene oxide continues to increase, and the surface activity begins to decrease again. The fatty alcohol-polyoxyethylene ether has good compatibility with other surfactants, is insensitive to hard water, has good low-temperature washing performance, and is stable to hydrolysis when the pH is within the range of 4-10. No toxicity, no irritation, good affinity with skin, high efficiency, low foam and easy washing, and is similar to natural phospholipid.

Further, the solubilizer is any one of or a combination of two of polysorbate, polyoxyethylene fatty acid ester and laureth ester in any proportion. Polyoxyethylene fatty acid esters are important surfactants, range in appearance from amber liquid to milky white solid, and belong to nonionic surfactants. Can be dissolved in water, ethanol and higher fatty alcohol, has good surface activity of emulsification, solubilization, wetting, dispersion, softness, antistatic property and the like, and is non-toxic and non-irritant. Therefore, the method has extremely wide application in industries such as cosmetics, medicines, foods, pesticides, paper making, textile processing and the like. The polyoxyethylene fatty acid ester has strong detergency, and the active substance of which the hydrophobic group raw material is pure lauric acid has higher detergency value than the active substance of which the hydrophobic group raw material is pure palmitic acid under the condition that the hydrophilic group polymerization degree is 10.

Further, the preservative is any one or a composition of two of sodium benzoate and benzoic anhydride in any proportion. Benzoic acid and sodium benzoate have bactericidal and bacteriostatic effects and are low in toxicity and odorless, and thus they are widely used as preservatives. In slightly acidic media, only 0.1% concentration of benzoic acid inhibits bacterial growth. The pH value is changed to greatly influence the bactericidal action and the bacteriostatic action of benzoate, the effect is obviously reduced in a reducing medium, and the effect is optimal when the pH value is 2.5-4.5. In consideration of the influence of later-stage placing conditions and time, the proper preservative is added, the product use experience degree is improved, and the product quality can be guaranteed without falling of the grade.

Further, the dispersing agent is any one of or a composition of two of methylene dinaphthalene sodium sulfonate, methylene dinaphthalene sodium sulfonate and polyethylene glycol in any proportion. The methylene dinaphthalene sodium sulfonate is an anionic surfactant, has good diffusibility and low foaming capacity, and can be mixed with other anionic and nonionic surfactants. Mainly used as a leveling agent for dyeing, a dispersant for preparing lakes and also used as a diluent for vat dyes.

Further, the bactericide is any one or a composition of two of trichlorocarbanilide, benzalkonium chloride and polyquaternium in any proportion. The polyquaternium flocculating bactericide belongs to a strong cationic high molecular polymer, has good solubility in water, belongs to a non-oxidizing bactericide flocculant, has broad-spectrum and high-efficiency sterilization and algae killing capability, can effectively control the reproduction of bacteria and algae and the growth of slime in water, has good slime stripping effect and certain dispersion and permeation effects, and simultaneously has certain deoiling and deodorizing capabilities and corrosion inhibition effects. The polyquaternium bactericide flocculant can be used as a bactericide and mildew inhibitor, a softening agent, a conditioner and the like in the textile printing and dyeing industry.

Further, the antistatic agent is one or a combination of two of monoalkyl ether phosphate potassium salt, ethoxylated alkyl amine and ethoxylated lauryl tyramine in any proportion. The monoalkyl ether phosphate potassium salt is alcohol ether type nonionic modified phosphate anionic surfactant, is colorless or yellowish transparent liquid, and has certain unique functions due to the existence of phosphorus atoms; has better electrolyte compatibility, thermal and alkali stability, excellent antistatic property, lubricating property, corrosion resistance and the like, so the surfactant is used as a special surfactant and is widely applied to the fields of chemical fibers, textiles, leather, plastics, paper making, cosmetics and the like.
