Abstract

Antistatic agent composition having improved flexibilities and hygroscopic properties was prepared. Various kinds of fatty acids and aminoethyl ethanolamine were reacted at 170 deg.C for 3 hours, at 190-200 deg.C for 3-8 hours to synthesize 2-alkyl-1- hydroxyethyl -2-imidazoline, followed by the reaction of dimethyl sulfate to give compound(I). 5 Mol of ethylene oxide was added in monoalkylamine to give compound(II). The antistatic agent composition was prepared from compound(I) and (II) at the ratio of 4:6.

Description

Antistatic Agent Composition for Textile Surface Coating

This invention relates to the composition of the antistatic agent for fiber surface coatings obtained by mixing imidazoline type compound formula (1) and quaternary ammonium salt type compound formula (2) in fixed ratio.

R ₁ is a stearyl group, a palm fatty alkyl group, or the like, and R ₂ is a tallow fatty alkyl group.

(Conventional technology)

Synthetic fibers and semi-synthetic fibers have various superior physical properties compared to natural fibers such as wool, cotton, and silk, but also have drawbacks not found in natural fibers. One of them is the possibility of static electricity.

When static electricity is generated, various problems occur in the spinning process, and even when used as a product, it is easy to get dust, and it may be caused to stick to each other or make noise when removing clothes. If the electrical resistance of the fiber surface is sufficiently lowered, the effect of preventing static electricity is generated, and the antistatic agent used for such purpose is classified into cationic, nonionic, anionic and simple materials, and the number thereof is very large.

The above formulas (1), (2), etc. are also one of the cationic compounds, and each of them has been used alone, but an object thereof is to provide a composition having better antistatic properties.

(Means to solve the task)

In the present invention, in order to solve the above problems, R ₁ of the compound of formula (1) was synthesized by introducing oleic acid, stearic acid, palm fatty acid, and the like, and R ₂ of compound of formula (2) was synthesized by Uji fatty alkyl, A composition of an antistatic agent is obtained, which comprises compound formulas (1) and (2) in a 4: 6 composition.

When the present invention is described in detail, various types of fatty acids and aminoethylethanolamine (AEEA) are reacted at 170 ° C. for 3 hours under a nitrogen atmosphere, and then heated to 190 ° C. to 200 ° C. and then reacted for 3 to 8 hours. Alkyl-1-hydroxyethyl-2-imidazoline is synthesized, and dimethylsulfate (DMS) is applied to the imidazoline to obtain compound of formula (1). In addition, dimethylsulfate (DMS) is applied to a compound in which 5 moles of ethylene oxide (E.O) is added to a monoalkylamine to obtain quaternized compound formula (2). These two compounds obtain a composition of 4: 6 and measure their flexibility, antistatic and hygroscopicity.

For example, it will be described in detail as follows.

Example 1

1-1. Into a 500 ml four-necked round bottom flask equipped with a stirrer, a cooler, and a thermometer, 0.5 M (141 g) of stearic acid was heated and heated to about 60 to 70 ° C., followed by 0.5 M (52 g) of AEEA. Dropped over minutes.

After the reaction temperature was raised to 170 ° C. and maintained for 3 hours, the pressure was reduced to 2 to 3 torr at the same temperature, followed by dehydration for 5 hours.

After the temperature of the reaction solution was lowered to 40 ° C., the total amine value was measured, and the corresponding amount of dimethyl sulfate was slowly added to prepare 2-stearyl-1-hydroxyethyl-2-imidazolium methyl sulfate (SIMS). . Isopropyl alcohol was added to give a solid content of 75%.

1-2. 5 moles of ethylene oxide was added to 1 mole of Uji fatty alkylamine, and this was added to the reactor as in 1-1 above, followed by quaternization by slowly adding 1 equivalent of DMS while maintaining the temperature of the reaction solution at 50 ° C. or below. Uji fattyalkyl (5EO) methylammonium methylsulfate (TN5MS) was prepared. Isopropyl alcohol was added to the reaction to obtain a solid content of 75%.

1-3. Simultaneously mix the SIMS and TN5MS prepared in 1-1 and 1-2 above to apply a certain amount (PET: 19.7% of pore weight, cotton: 14.2% of pore weight) to cotton cloth, polyester cloth, and flexibility (Feeling Meter) FM-2, Uenoyama kiko), hygroscopicity (immersion method), antistatic property (Super megohmo-meter SM-5E, TOA Electronics LTD) were measured, and the results are shown in Table 1.

Example 2

2-1. Example 1-1 was similarly carried out except that palm fatty acid was used instead of stearic acid, to prepare 2-cocofatty-1-hydroxyethyl-2-imidazolium methyl sulfate (CIMS).

2-2. Above 2-1 CIMS and 1-2 TN5MS mixed composition was applied to a cotton cloth, polyester fabric a certain amount (same as 1-3) and measured the flexibility, absorbency, antistatic properties, the results are shown in Table 2 It was.
