Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an oil for textile treatment, and more specifically,
This invention relates to a fiber processing oil that imparts excellent flexibility and smoothness to filamentous fiber products and improves knitting and weaving properties.

[Conventional technology]

Generally, when producing textiles by knitting or weaving filamentous fiber products, knitting and weaving will be difficult if the yarns do not have desirable flexibility and smoothness.

In particular, bleached or dyed threads lack flexibility and smoothness, so after bleaching or dyeing, softeners and smoothing agents such as various waxes, oils and fats, surfactants, etc. are applied to cheese collectors, Alternatively, oiling is performed using a jet collector to impart flexibility and smoothness to the filament.

However, in recent years, knitting and weaving have become faster, and the production of more complex textiles has increased. for example,
For weaving on high-speed looms such as air jet looms and for complex knitting such as rope knitting, the conventional oils for fiber processing do not have sufficient flexibility and smoothness, making it extremely difficult to obtain weaving properties. The quality of knitted fabrics is also extremely poor.

A common way to deal with this problem is to use conventional fiber treatment oils, such as the ammonium salt distearyldimethylammonium chloride (Japanese Patent Publication No.
-23585, JP-A No. 62-69882, etc.), those using Arkobel-type softeners, and those using a 1:1 molar dehydrated compound of stearic acid and N-aminoethylethanolamine (JP-A-62-69882, etc.) Publication No. 58-60070, etc.)
Attempts were made to oil the yarn at high temperatures.

[Problem to be solved by the invention]

However, with this method, the oil adheres unevenly and unevenly to the yarn, causing the oil to powder in areas where it is highly adhered, leading to yellowing and discoloration of the yarn, which impairs the quality of the product. Extremely damaging. In addition, in areas where the amount of oil adhering is small, thread breakage occurs during knitting or weaving, which not only lowers production efficiency but also significantly lowers the quality of the finished product.

Furthermore, conventional oils have poor adsorption to yarn (
For example, since the adhesion rate is less than 40% of the treatment concentration), a high concentration of oil remains in the waste liquid after oiling, making it difficult to treat the waste liquid. The reality is that a fiber treatment oil with uniform adhesion and excellent flexibility and smoothness has not been obtained.

The present invention has been made in view of the above-mentioned points of view, and is an oil agent for treating fibers that has improved flexibility, smoothness, and adsorption properties. In other words, its excellent flexibility and smoothness enable high-speed weaving and complex knitting, and its uniform and high adsorption properties
The purpose of the present invention is to provide an oil for textile treatment that can improve product quality, have economic effects by reducing the amount of oil used, and reduce the burden of wastewater treatment.

[Means to solve the problem]

As a result of extensive research into the relationship between adhesion to threads and processing oil composition, the present inventors have found that they have excellent flexibility, smoothness, and The present invention was completed by discovering a composition that imparts adsorption properties.

That is, the fiber treatment oil according to the first invention has the following (a)
) Amine acylamide represented by the general formula, R, C0NH
C, H2, NR2 (Ra ) (wherein R is an alkyl group or alkenyl group having 11 to 23 carbon atoms, R,
, R, is an alkyl group having 1 to 4 carbon atoms, and n is an integer of 2 to 5. ), (b) a wax having a melting point of 40 to 110°C, and (c) a surfactant.

The fiber treatment oil according to the second invention is such that (a) the amine acylamide is 5 to 50 parts by weight when the total of the amine acylamide, wax, and surfactant represented by the above-mentioned general formula is 100 parts by weight. (b) wax in an amount of 40 to 80 parts by weight, and (C) a surfactant in an amount of 10 to 40 parts by weight.

The amine acylamide is a component for imparting adsorption and uniform adhesion to the yarn. In addition, this component imparts preferable flexibility to the yarn and has the effect of not inhibiting the smoothness due to wax.

In the above general formula, the number of carbon atoms of group R1 is 11 to 23
This is because if it is less than 11, good flexibility cannot be obtained, while if it exceeds 23, the water solubility is poor and a stable processing solution cannot be obtained. In addition, this amine acylamide is
It is a compound obtained by dehydration condensation of a fatty acid having an alkyl group or an alkenyl group having 11 to 23 carbon atoms and a diamine. As this diamine, dimethylamine propylamine, diethylaminopropylamine, dibutylaminopropylamine, diethylaminoethylamine, dimethylaminoneopentylamine (dimethylamino 2,2-dimethyl 1-propylamine), diethylamino 2-pentylamine, etc. may be used. I can do it.

The content of this amine acylamide is 5 to 50% by weight (
Hereinafter, it will simply be referred to as %. ) is appropriate. If it is less than 5%, the adsorption of the oil agent will decrease, resulting in poor flexibility and smoothness, while if it exceeds 50%, the amount of wax, which is a smoothing component, will decrease, making it impossible to obtain sufficient smoothness. .

The wax is a component mainly for imparting smoothness to the yarn. The wax used in the present invention is
A suitable melting point range is 40 to 110°C. Melting point is 40
If it is less than 110°C, the smoothness will be insufficient, and if it exceeds 110°C, the emulsion stability, especially the mechanical stability, will decrease, making it difficult to uniformly adhere to the yarn, and sloping will likely occur.

Examples of the wax include natural and synthetic hydrocarbon waxes, glycerides and waxes, as well as oxides and acid-modified substances thereof. Natural waxes include hydrogenated hydrogenated oil made by hydrogenating beef tallow or lard,
Animal and vegetable waxes such as beeswax, hydrogenated whale wax, carnauba wax, candelia wax, wood wax, bran wax,
paraffin wax, microcrystalline wax,
Examples include mineral waxes such as montan wax and sericin wax. Further, examples of the synthetic wax include low molecular weight polyethylene wax, polypropylene wax, wax produced by the Fischer-de-Busch method, and the like.

The content of this wax is suitably in the range of 40 to 80%. This is because if it is less than 40%, the smoothness will be insufficient, while if it exceeds 80%, flexibility or emulsion stability will decrease. The surfactant (c) is used to stably emulsify the components in water. As the surfactant used in the present invention, nonionic surfactants and/or cationic surfactants are suitable.

Examples of the nonionic surfactants include sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, propylene glycol pentaerythritol fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbitol fatty acid ester, polyoxyethylene glycerin fatty acid ester, Polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene castor oil (hydrogenated castor oil), polyoxyethylene lanolin (
lanolin alcohol), polyoxyethylene beeswax derivatives, poly1+diethylene alkylamine, polyoxyethylene alkylphenyl formaldehyde condensates, polyoxyethylene pentaerythritol fatty acid esters, polyoxyethylene fatty acid amides, fatty acid alkanol deamides, and the like.

Examples of cationic surfactants include polyoxyethylene alkylamine salts, alkylammonium salts, alkylbenzylammonium salts, alkylamine salts, alkylpyridium salts, alkylquinolium salts, alkylimidazolium salts, alkylalkanolamine salts, and acylamine salts. , polyoxyethylene alkylammonium salts, and the like.

The content of the surfactant is suitably in the range of 10 to 40%. If this content is less than 10%, the emulsion stability will decrease and the oil agent will not adhere uniformly to the threads, causing powdering. Moreover, if the content exceeds 40%, the adsorption property will be inhibited, or the content of the amine acylamide and wax will inevitably decrease, making it impossible to obtain flexibility and smoothness, and furthermore, the burden of wastewater treatment will increase. I don't like it because it gets bigger.

In addition to the above essential components, the oil agent of the present invention may appropriately contain a preservative, a thickener, an antifoaming agent, an antifungal agent, an antioxidant, and the like.

In order to treat yarns using the oil agent of the present invention, for example, the oil agent is emulsified in water and supplied as an emulsion with a concentration of 5 to 50% by an exhaustion method. As the exhaust method, injection type, rotary back type, cheese type, wince type dyeing machines, etc. are suitable. The treatment liquid is prepared by diluting it when refueling, but it may also be used by directly refueling. The amount of oil supplied is 0 for the fiber yarn.
．． 1 to 10% is appropriate. In addition, the processing temperature is 10 to 9
5°C is appropriate.
