Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a textile oil, and more specifically to a polyoxyalkylene fatty acid used to smooth the textile process, which is a textile processing process, and to improve the quality of textiles. The present invention relates to a textile oil containing an amide type nonionic surfactant.

Textile oils provide fibers (spun yarn, etc.) with excellent smoothness, electrical resistance, and flexibility, and prevent damage to the fibers from external substances added to the fibers during the textile process. This textile oil is adsorbed in a layer on the fiber surface and exerts its effect. In addition, the m@ oil agent is used in the form of an aqueous solution or an emulsified dispersion state in the process of adhering it to the fiber surface.

Conventionally, hydrocarbon waxes, natural or synthetic waxes, etc. have been used as oils for textiles, polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxyprobylene glycol, glycerin fatty acid esters, sorbitan fatty acid esters, polyoxy It is well known that it is possible to use emulsified dispersions with nonionic surfactants such as ethylene sorbitan fatty acid esters, but in order to obtain emulsified dispersions that are stable enough to be used as textile oils, it is necessary to The content of wax in the emulsified dispersion could not be increased sufficiently, and therefore sufficient performance (smoothness, etc.) could not be imparted.

In addition, even if the smoothness was satisfied, the electrical resistance and flexibility were poor and there were problems with practicality.

Furthermore, even if smoothness, electrical resistance, and flexibility are satisfied, the emulsion stability is poor, and in the process of attaching it to the fiber surface, the emulsion stability (forced circulation of the treatment bath with a pump, etc.) However, there was a problem with the destruction of the emulsified dispersed particles, and there was no product that comprehensively satisfied the above performance.

In light of these circumstances, the present inventors have conducted extensive research and discovered that an extremely stable emulsified dispersion can be obtained by using a specific nonionic surfactant, and that the above-mentioned properties can also be imparted to fibers. We have arrived at the present invention.

That is, the present invention is based on a higher fatty acid having 8 to 24 carbon atoms and a polyester represented by the general formula (11% formula % (in formula C, n is an integer of 1 to 3, and m is an integer of 2 to 9). The present invention provides a textile oil containing a nonionic surfactant obtained by adding an alkylene oxide to an amide compound obtained by dehydration condensation of an alkylene polyamine.

The higher fatty acid having 8 to 24 carbon atoms according to the present invention may be either saturated or unsaturated, and may be a mixture of various fatty acids. Examples of these fatty acids include saturated fatty acids such as caprylic acid, capric acid, lauric acid, palmitic acid, stearic acid, and behenic acid, unsaturated fatty acids such as oleic acid, and mixed fatty acids such as coconut oil fatty acid, palm oil fatty acid, and beef tallow fatty acid. Among them, stearic acid and behenic acid are preferred.

Examples of the polyalkylene polyamine represented by the general formula (Il) include diethylenetriamine, triethylenetetramine, and tetraethylenepentamine.

The molar ratio of higher fatty acid and polyalkylene polyamine is 3/
1 to 1/1 is preferable.

The condensation reaction is carried out at 120 to 200C while being dehydrated.

A solvent such as benzene or toluene is used if necessary.

Dehydration is accomplished by azeotropy, reduced pressure, or rectification.

In addition to ethylene oxide, the alkylene oxide may be a mixed alkylene oxide (regardless of random or block) of ethylene oxide and propylene oxide or butylene oxide. however,
In the mixed alkylene oxide, it is necessary that the ethylene oxide content is 50% by weight or more.

From the viewpoint of emulsion stability, ethylene oxide alone is particularly preferred.

The number of moles of alkylene oxide added is 1 to 50 moles, preferably 3 to 30 moles, per mole of the starting polyalkylene polyamine.

The addition reaction is carried out by a known method. For example, this is carried out by blowing alkylene oxide into the condensed amide compound at 130 to 170 C in the presence of an alkali catalyst.

The nonionic surfactant (

When treating fibers with the textile oil of the present invention, the above-mentioned nonionic surfactant 0.5 to 2011/13, smoothing component 1
It is preferable to process as an emulsified aqueous solution with a concentration of ~too#/4.

The nonionic surfactant according to the present invention provides emulsifying properties, antistatic properties, and texture (softness) by itself, but this does not preclude the addition of other emulsifiers and antistatic agents as necessary.

The fibers treated with the textile oil of the present invention may be either natural or synthetic fibers, and include wool, acrylic, polyester, polyamide, cotton, and mixed fibers thereof.
