Technical Field

The invention relates to the field of textile auxiliaries, in particular to a preparation method of an environment-friendly and durable fabric antistatic agent.

Background

Many textiles now contain a large amount of synthetic fibers, which have many superior properties to natural fibers, and thus have been rapidly developed and widely used in recent years. For example, the invention of polyester fiber in 1941 is a synthetic fiber spun by a fiber-forming polymer in which each chain unit in a macromolecular chain is connected through an ester group. However, many synthetic fibers are hydrophobic fibers, have poor conductivity and are poor conductors, and synthetic fibers have amorphous portions as cotton fibers, but lack moisture absorption centers, and have moisture absorption rates of only 0.6% to 0.8% even at 100% relative humidity. Therefore, static electricity is easily generated and dust is easily adsorbed, and static electricity is more easily accumulated. The obvious disadvantages of the material as the clothing material are strong static electricity and poor moisture absorption. In the spinning, weaving, printing and dyeing processes and even in the actual taking process, static electricity is generated, so that much inconvenience is brought to the spinning process, the wearing application and the like.

CN109371674A discloses a preparation method of a textile antistatic agent. The existing antistatic agent can be compounded with an eight-carbon fluorine-containing waterproof agent, but when the antistatic agent is compounded with a six-carbon fluorine-containing waterproof agent and a fluorine-free waterproof agent, the waterproof effect is greatly influenced. The main structure of the antistatic agent is short-chain fatty alcohol or phosphate monoester of fatty alcohol containing 2-3 hydroxyl groups, and the adopted preparation method comprises the following steps: firstly, short-chain fatty alcohol or fatty alcohol containing 2-3 hydroxyl groups reacts with a phosphorylation reagent, deionized water with the weight of 2-6% of that of a phosphorylation product is added for hydrolysis, then alkali is used for neutralization to obtain a phosphate product, and finally a chelating dispersant with the weight of 2-5% of that of the phosphate product is added for compounding to obtain a finished product; the chelating dispersant is prepared by reacting tristyrylphenol polyoxyethylene ether with gluconic acid, and the reaction temperature is 170-180 ℃. The antistatic agent can be compounded with six-carbon fluorine-containing waterproof agent, fluorine-free waterproof agent and silicone oil, has little influence on the waterproof effect and the hand feeling of the silicone oil, and has excellent antistatic performance.

CN103668971A relates to a special antistatic finishing agent for textiles, which is mainly used for the antistatic after-finishing process of artificial and natural fiber textiles, so that the textiles have the characteristics of antistatic property, static elimination, antibiosis and dust prevention. Has the advantages of simple preparation, convenient use, permanent antistatic property, water washing resistance, no irritation and no toxic or side effect.

CN103668941A provides an antistatic nano finishing agent for rabbit hair textiles and a finishing process. The finishing agent takes nano ZnO as a main component and takes a green and safe surfactant as an auxiliary component, ensures the specific appearance quality and performance of the rabbit hair fiber on the basis of excellent biocompatibility and environmental friendliness, and particularly shows incomparable advantages on the performances of antistatic effect, ultraviolet protection, antibiosis, bacteriostasis and the like. The optimized finishing process not only ensures that the nano finishing agent is well attached to the surface of the fiber when acting with rabbit hair textiles, is filled to the included angle of the scales and even the medullary cavity, and interacts with the fiber to generate valence bond combination to form a continuous and stable functional nano film, so that the finished rabbit hair textiles have antistatic, ultraviolet-proof, antibacterial and bacteriostatic properties and good mechanical properties, but also are convenient to operate and suitable for industrial use and popularization.

The principle of antistatic finishing is to form a highly conductive layer on the surface of the fibers. The antistatic agent can endow the surfaces of the fibers and the resin with certain hygroscopicity and ionicity, so that the conductivity is improved, and the antistatic purpose is achieved; however, the antistatic finishing agent prepared by the technology is easy to migrate on the surface of the fabric, and the antistatic effect is easy to lose after a long time.
