Description

A kind of fabric antistatic agent and its preparation method and fabric care composition

technical field

The invention relates to a fabric care composition, which belongs to the technical field of daily chemical fabric care products, in particular to a fabric care composition capable of significantly improving the antistatic performance of fabrics.

Background technique

In dry winter, people usually wear clothes made of various materials, such as down jackets, sweaters, cotton clothes, and polyester chemical fiber clothes. When people move around, the clothes will rub against each other to generate static electricity, and those with poor conductivity The surface of the fabric will accumulate static electricity. The accumulation of static electricity on the fabric is not only easy to absorb dirt and cause pollution. When the static electricity is released from the human body, it will also make people feel electric shock pain. The development of fabric care products with antistatic function can meet the needs of consumers and has broad market prospects.

Modern science tells us that any object is composed of atoms, and atoms are composed of positively charged nuclei and negatively charged electrons, and electrons move around the nucleus. Under normal circumstances, the number of positive charges carried by the nucleus is equal to the number of negative charges carried by the electrons outside the nucleus, and the atom has no electrical properties, so the whole object is neutral. The number of positive charges in the nucleus is difficult to change, but the electrons outside the nucleus can get rid of the shackles of the nucleus and transfer to another object, thus changing the number of negative charges carried by the electrons outside the nucleus. When an object loses electrons, the total number of negative charges of its electrons is less than the positive charge of the nucleus, and it shows positive charge; on the contrary, when an object that is originally neutral, it shows negative charge when it gains electrons.

When two objects rub against each other, because the nuclei of different objects have different abilities to bind extranuclear electrons, one object loses some electrons and becomes positively charged, while the other object gains excess electrons and becomes negatively charged. For example, people wearing clothes of different materials generate static electricity due to body movement, polyester fabrics rub against wool clothes, electrons on the wool are transferred to polyester, wool is positively charged, and polyester fabric is negatively charged.

The amount of charge on the fabric in the same environment depends on two factors: one is the ease of electrification between fabrics of different materials, which is determined by the friction of the fabric and the difference in the binding of charges by different fabric materials; the other is the electrical conductivity of the fabric That is, the size of the resistance, the greater the resistance, the poorer the conductivity, and the easier it is for static electricity to accumulate. Among all kinds of commonly used materials for clothing, polyester and other chemical fiber fabrics have poor antistatic properties. On the one hand, polyester is easy to rub against animal hair to generate static electricity; on the other hand, polyester has a large resistance and is not easy to conduct electricity. accumulated. Therefore, generally speaking, fabric antistatic technology is mainly for polyester and other chemical fiber fabrics.

The mechanism of antistatic agent is to adsorb hydrophilic substances on the fabric through van der Waals force or electrostatic force to change the properties of the fabric surface, which can reduce the friction coefficient of the fabric surface and thus reduce the probability of frictional electrification, such as softener. The adsorption of water substances on the surface of the fabric can reduce the surface resistance of the fabric. Generally, the electrostatic adsorption force will make the antistatic agent more firmly adsorbed on the fabric, so the fabric antistatic agent is mostly cationic. Most of the currently commercially available fabric softeners claim to have an antistatic function. The main component of the softener is a quaternary ammonium salt cation containing a hydrophobic chain. slippery effect.

Chinese patent CN 101935949 B discloses a fabric softener, which contains 4% to 6% of ditallow ethyl ethyl hydroxyethyl ammonium methyl sulfate; Chinese patent CN 103541220 A discloses a fabric softener Softener, the softener contains 5% to 8% of dialkyl dimethyl quaternary ammonium salt; Chinese patent CN 103669000 A discloses an antistatic fabric softener and its preparation method, the softener contains 0.1 to 0.5 Parts of ester quaternary ammonium salt. There are also formulation engineers who have developed detergents with antistatic and supple functions, which is the very popular concept of washing and care in one. Such detergents also usually use quaternary ammonium salt cations with hydrophobic chains as antistatic agents. Akezo Nobel Co., Ltd. patent CN101454433 B discloses an aqueous laundry detergent composition with improved softening and antistatic properties, which comprises at least one amidoalkylamine quaternary ammonium compound. Chinese patent CN 102676314 A discloses an antistatic detergent, in which the antistatic agent used is trishydroxyethylmethyl quaternary ammonium methylsulfate.

The antistatic agents of the above-mentioned prior art are all quaternary ammonium salt cations containing hydrophobic chains. We have found that the antistatic properties of the above-mentioned antistatic agents are not ideal, because the hydrophobic groups of the antistatic agents adsorbed on the surface of the fabric cannot produce good results. electrical conductivity.

Contents of the invention

In order to solve the above-mentioned problems in the prior art, the object of the present invention is to provide a fabric antistatic agent and a fabric care composition containing the antistatic agent, which can significantly improve the antistatic performance of fabrics, especially chemical fiber fabrics.

Summary of the invention

Most of the substances traditionally used in fabric care to improve the antistatic performance and softness of fabrics are cations, which are mostly compounds composed of hydrophobic chains and quaternary ammonium salts. Actual consumer use and experimental tests have shown that the structure of Cationic antistatic performance is not satisfactory. Surprisingly, we found that the antistatic performance of the alkyl quaternary ammonium salt was significantly improved after introducing hydrophilic groups.
