Description
Technical Field
The invention relates to a low-foam degreasing agent, in particular to an environment-friendly low-foam degreasing agent for polyester fabrics and a preparation method thereof.
Background
The polyester fiber is continuously rubbed in the spinning and weaving process, so that a large amount of static electricity is easily generated, and the textile processing is influenced. In order to eliminate static electricity generated by fiber friction and reduce the end breakage rate, proper oil agents are required to be added, and the oil agents mainly comprise spindle oil, gear oil, white mineral oil, black engine oil and the like. The addition of the oil agent is unfavorable for the subsequent dyeing and finishing process of the fiber, the oil agent and oil stain are required to be thoroughly removed when the fabric is degreased, otherwise, the subsequent dyeing and finishing process is greatly damaged, and the fabric has the problems of color spots, color defects and the like.
When the polyester fabric is subjected to an intermittent oil removing process, the internal part of the overflow machine is high in temperature and pressure, and the working solution continuously circularly flows and impacts the cylinder wall to generate a large amount of foam, so that the following problems are caused:
(1) greasy dirt, impurities and the like removed from the working solution are easy to float in the foam and cause rewetting after contacting with the fabric.
(2) When too much foam is generated, the overflow machine is easy to generate 'empty suction', so that the fabric blocks the cylinder.
In the prior patent, a method of adding a defoaming agent is mostly adopted for reducing the foam of the auxiliary agent, but most of the defoaming agent is organic silicon, and under the conditions of high temperature and high pressure of an intermittent oil removal process, the organic silicon component in the defoaming agent is extremely unstable, is easy to break emulsion and separate out stained fabrics, and generates silicon spots.
The Chinese patent with publication number CN109370795B, entitled "oil removing agent for continuous processing of polyester/ammonia and polyamide-ammonia blended knitted fabric and preparation method thereof" discloses an oil removing agent for continuous processing prepared by polyoxyethylene type nonionic surfactant, chelating agent, fluorocarbon surfactant, organic fluorine finishing agent and other surfactants, which has good oil removal property, emulsifying dispersion property, anti-sticking property and rapid permeability, but the organic fluorine in the components is not beneficial to environmental protection.
The Chinese patent with the publication number of CN110527601A and the name of 'a low-temperature degreasing agent for chemical fiber fabrics and a preparation method thereof' discloses a low-temperature degreasing agent which takes fatty alcohol-polyoxyethylene ether containing alkyl glucoside, fatty alcohol-polyoxyethylene ether phosphate containing alkyl glucoside and fatty alcohol-polyoxyethylene ether sulfonate containing alkyl glucoside as main components, and has good decontamination property, degreasing property and dispersibility, but the degreasing agent has high foam, and impurities such as oil stains and the like removed in a degreasing process are easy to float in the foam and cause back staining and even cylinder blocking after contacting with fabrics.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides an environment-friendly low-foam degreasing agent for polyester fabrics and a preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
the environment-friendly low-foam degreasing agent for the polyester fabric comprises the following preparation raw materials in parts by mass:
20-25% of dodecene glycol polyoxyethylene ether, 10-15% of methyl laurate polyoxyethylene ether sulfonate, 5-10% of straight chain lauryl alcohol polyoxyethylene ether and the balance of deionized water.
Preferably, the EO number of dodecenyldiol polyoxyethylene ether is 12, the EO number of methyl laurate polyoxyethylene ether sulfonate is 7, and the EO number of linear dodecanol polyoxyethylene ether is 9.
The preparation method of the environment-friendly low-foam degreasing agent for the polyester fabric comprises the following steps of:
(1) converting the mass percent of the components of the oil removing agent into specific mass and weighing the raw materials;
(2) adding methyl laurate polyethenoxy ether sulfonate and straight chain lauryl polyethenoxy ether into deionized water, and stirring and mixing uniformly;
(3) and (3) adding dodecenyl diol polyoxyethylene ether into the mixed solution obtained in the step (2), and then stirring and mixing uniformly to obtain the finished environment-friendly low-foam degreasing agent.
According to the preparation method of the environment-friendly low-foam oil removing agent for the polyester fabric, the anionic surfactant and the nonionic surfactant are compounded and synergized, the dodecene glycol polyoxyethylene ether has extremely low dynamic surface tension, and in the intermittent oil removing process of the polyester fabric, the foam can be effectively inhibited under the dynamic condition without adding a defoaming agent, so that oil stains and impurities are prevented from floating in the foam to cause adhesion return; the silicon spot problem of the defoaming agent is avoided; and the unsaturated alkynyl contained in the oil remover can enhance the emulsification and dispersion performance of the oil remover and improve the oil removing effect of the oil remover.
