Description

[Detailed description of the invention] The present invention relates to a treatment agent for synthetic fibers.

Conventionally, there is a treatment agent for synthetic fibers containing an alkyl phosphate ester, but fibers treated with this agent did not have a sufficient antistatic effect.

The present inventors have arrived at the present invention as a result of intensive studies to solve the above problem.

That is, the present invention is a treatment agent for synthetic fibers characterized by containing a phosphoric acid mono- and/or diester salt of a monohydric alcohol having a branched hydrocarbon group having 20 or more carbon atoms.

In the present invention, in the phosphoric acid mono- and/or diester salts of monohydric alcohols having a branched hydrocarbon group having 20 or more carbon atoms, Examples include m-alcoalkylene oxide adducts having m-alcoalkylene oxide adducts.

The -hydric alcohol has the general formula (where m and 11 are integers of 1 or more, m 41.
is an integer greater than or equal to 18. ) is opened.

The group CCml1z++ and the C port H2o +H may be linear or branched.

Iη10 is preferably 22-32. When n)+n is less than 18, the antistatic effect is poor.

Further, in the case of linear higher alcohols, there are problems such as poor antistatic effect and poor compatibility f1 with smoothing agents and surfactants.

As a -hydric alcohol having a branched hydrocarbon group having 20 or more carbon atoms represented by the general formula (1), m = 10,

The number of moles added is usually 1 to 5 moles, preferably 1 to 3 moles.

In addition to the m alcohols having two branched hydrocarbon groups having 20 or more carbon atoms, other alcohols may be used if necessary. ethylhexyl alcohol, tritethyl alcohol, oleyl alcohol)
, polyhydric alcohols (such as pentaerythritol). In this case, the content of m alcohols having branched hydrocarbon groups having 20 or more carbon atoms is usually 30
At least 2 mol%, preferably at least 50 mol%1.

In the present invention, the phosphoric acid ester salts include salts of alkali metals, organic amines (alkanolamines such as mono-, triethanolamine, isopropanolamine; alkylamines such as octylamine, laurylamine, oleylamine), and salts thereof. A mixture of two or more types of salt can be prepared. Among these, preferred are Na and Na salts.

The phosphoric acid ester salts used in the present invention include monoalkyl phosphoric acid ester salts and dialkyl phosphoric acid ester salts, singly or as a mixture, but are generally mixtures, and the molar ratio of the monoester salt to the diester salt is usually 2:1 to 1. :
2 in a/l).

The preferred ratio is around 1:1.

In the present invention, when phosphoric acid triester is used in place of phosphoric acid mono- and/or diester salt G, the antistatic effect is poor.

In the present invention, the phosphoric acid ester salt generally comprises m alcohols and/or alcohols having a branched hydrocarbon group having 20 or more carbon atoms.
Alternatively, it can be obtained by reacting the alkylene oxide addition product with P2O5 and neutralizing the product with a salt-forming basic compound such as an alkali metal.

In the reaction, the molar ratio of P2O5 to m alcohols having a branched hydrocarbon group having 20 or more carbon atoms and/or their alkylene oxide adducts is usually 1:2 to 45, preferably 1:3. If the molar ratio of m alcohols having two branched hydrocarbon groups having 20 or more carbon atoms and/or their alkylene oxide adducts is less than 2, friction will increase, and if it exceeds 45, the antistatic properties will decrease.

Anti-J・C temperature is usually 50 to 130℃, preferably 60℃
~110°C.

The neutralization method may be the same as a conventional method.

The processing agent of the present invention contains a leveling agent and/or surfactant (emulsifier and/or antistatic agent) and other additives as necessary in addition to the phosphoric acid ester salt of the present invention.

As the smoothing agent, mineral oil (such as one having a release time of 60 to 500 seconds at 30 DEG C.) and a carboxylic acid ester (usually having 20 to 40 carbon atoms) are used.

Examples of the carboxylic acid esters include (1)-picture alcohols (such as aliphatic alcohols, the same applies hereinafter) or their alkylene oxides [ethylene oxide (abbreviated as EO), solohylene oxide (abbreviated as PO), etc., the same applies hereinafter] (t1 Esters of monocarphonic acids (aliphatic, aromatic, same hereinafter) such as oleyl oleate-1, oleyl laurate, isostearyl laure-1, butyl stearate, isooctyl palmite-1, in Octyl steer 1・

-70% (preferably 40-60%), surfactant: usually 30-70% (preferably 40-60%).

The treatment agent of the present invention can be used for synthetic fibers such as polyamide, polyester, polypropylene, and polyacrylic.

Examples of the fiber form include Neurament yarn (multifilament yarn), undrawn yarn-drawn yarn, knitted fabric, and the like.

The application period of the present invention (21) is the spinning process, the stretching process, the tithing process, etc.

The amount of the treatment agent applied can be varied depending on the purpose of treatment, but it is usually 0.2 to 2% by weight, preferably 0.4 to 1% by weight as a solid content applied to the fibers.

The treatment agent can be applied to the fibers in the form of an emulsion with water (the concentration of the treatment agent is usually 10 to 20% by weight) or in the form of a water-free [low viscosity liquid paraffin (Letwood seconds at 30° C. 30 seconds) or in the form of an organic solvent solution (20-50% by weight solution of an organic solvent such as a lower alcohol, halogenated hydrocarbon, or α-olefin oligomer9) by a lubricating method such as the 1-coke lubricating method or the nozzle lubricating method. can.

The treatment agent of the present invention is used as a treatment agent for synthetic fibers, and is applied to yarns at 1゛b.
For example, synthetic fibers such as nylon and polyester are generally produced by applying a fiber treatment agent to undrawn yarn obtained by melt spinning. After being applied, it is stretched several times,
Heat-scented for property fixation. These drawn yarns are further subjected to higher processing steps such as bulking, knitting, and weaving to become textile products. However, if these I u', f Kotoe are not sufficiently antistatic + h effect in the bulk processing process, when fabricated yarn is manufactured and wound up, a problem will occur in which the yarn will wind up on the roller due to static electricity.

In the case of item 1, if the treatment agent of the present invention is used, problems such as roller rolling will not occur.

Furthermore, the treatment agent of the present invention imparts excellent heat resistance to yarn.

For example, it reduces the amount of tar-like substances that adhere to the heater plate that performs heat setting during bulk processing.

It also has smoothness and anti-shedding properties.

The present invention will be further explained below with reference to Examples, Comparative Examples, and Test Examples, but the present invention is not limited thereto. The proportions are expressed in weight percent based on pure content.

When subjected to bulk processing at a heater temperature of 180 DEG C., the processing agents of the present invention (Examples 1 to 7) did not show any winding of the yarn around the rubber roller during false twist dotting due to static electricity. Furthermore, when the heater plate was observed after passing through K9 with a yarn amount of 5, there was almost no tar or oil decomposition products stuck on the heater plate, and the operability was extremely good.

Comparative processing agents (Comparative Examples 1 to 4) generated a lot of static electricity, and a phenomenon of winding around the rubber rollers occurred within one hour after starting false twisting, making it impossible to operate smoothly. Table 2 shows the results of testing and evaluation of the amount of tar material adhering to the rubber roller, electricity generated, and the amount of tar deposited on the heater brake 1.

The evaluation method is as follows: (1) Winding on rubber rollers 1. False twisting is performed under the bulk processing conditions, and whether or not the rubber rollers get tired immediately after the start of false twisting and during dotting after 1 hour of operation.
