Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a synthetic IF oil composition with excellent antistatic properties.

In the manufacturing process of synthetic materials such as nylon and polyester, providing smoothness, cohesiveness, antistatic properties, etc. by adding an oil agent is essential for smoothing the spinning, drawing, and processing processes. Required. Conventionally, lubricants with various compositions have been known, but the conventional lubricants are particularly sensitive to the guides, pins, rows, etc. that the threads to which they are applied are due to the antistatic agent component. Many of them caused wear of metal parts such as y and had too high viscosity.

The present invention is free from such drawbacks and provides an oil agent m-acid having superior antistatic properties. and(
b) The alkali metal salt or alkaline earth gold FA salt of alkenyl succinic acid is
The gist of the invention is an oil composition for synthetic fibers in which the total amount of (a) and (b) is 3 to 20% by weight.

Alkali metal salt or alkaline earth 311 gold salt of alkenyl succinic acid (hereinafter referred to as alkenyl succinate).

) is well known as described in 911' Japanese Patent Publication No. 56-26070. The purpose is to prevent pollution.

I and emulsification? A base oil consisting of ill (this is the antistatic t'l: is significantly improved when the surfactant supplease rIz agent and alkenyl succinate are used in a specific ratio). 4- It is possible to suppress the increase in viscosity, reduce the effect of abrasion on metal parts, and suppress the occurrence of yarn breakage and fuzz.

The Ii injection type antistatic agent in the present invention is as follows.

1 ion activator 1: Except for the combination of L agent and cationic activator, 2f・it I; J, upper υ [may be used. More specifically: (For example, as the alkyl phosphate metal salt, a metal salt of an acetic acid noester and a compound obtained by adding 1 to 10 moles of ethylene oxide (P2O) thereto, etc.
Alki/I/"t z + z Fe) Gold E Examples of gold include lauryl sulfonate sodium salt, oleyl sulfonate sodium salt, etc., argylsulfonate gold (as i1 salt).

Examples of alkenyl succinates include those in which the alkenyl group has 8 or more carbon atoms, such as decenyl, tothienyl, and hexadecenyl groups, and the metals include sodium, potassium,
Examples include calcium or magnesium.

In the present invention, the ratio (aXb) of the limiting -π creating molecule a) and the alkenyl succinic irb' Off.

(If the ratio of ql is too low, the electrical conductivity will be poor, and if the ratio of (b) is too low, the abrasion and adhesiveness will be reduced and the wood will fail; Deviate from the purpose.Also,

On the other hand, it is necessary to rub so that the total number of (a) and (bl) is 5 to 20%.If this amount is too small, 3%
If the amount is less than that, a sufficient antistatic effect cannot be obtained, and on the other hand, if the amount is too high and exceeds 20%, the smoothness will be poor and viscosity will occur, which is not preferable.

By applying the oil composition of the present invention to synthetic fibers, it is possible to prevent
can be done. That is, the stretching process.

In the temporary e processing process, the tire yarn twisting process, etc., the yarn is easily strained to prevent fuzzing due to charging.

Thread breakage can be prevented. 9 Oil agent i of the present invention
Since the fluffing effect on metal parts such as ids, pins, rollers, etc. is small, it is possible to prevent fuzzing and thread breakage due to wear of the metal parts.

Furthermore, since the oil composition of the present invention exhibits good antistatic property with a small number of antistatic agent components, it increases the conventional situation (171-) (i.e., antistatic properties that could not be used).

The present invention will be specifically explained using the following example.
+ 25 parts of hydrogenated castor oil E O + I additive 7: In a base oil consisting of 10 parts of Tobinoyl alcohol EO adduct, the composition of Table I and the potassium salt of ocucudecenyl succinic acid were added. Then, a 12q6 aqueous emulsion oil was prepared and applied to the spun yarn of nylon 6 using a roller oiling method.The nylon 6 was spun with a 210 denier/l//24 filament and stretched approximately 6 times to 70 A denier/24 filament !-Minzaka yarn was obtained.The Tomaribu yarn was 0,6 Q;'<% for 6 nylon yarns. Table 1 shows the results of evaluating antistatic properties and abrasion properties.

From the surface treatment, the combination of an antistatic agent and an alkali metal salt of alkenylsuccinic acid was used (this shows that the number of yarn breakages during stretching is reduced).

':'! UK Example 2 The antistatic agent shown in the table and the potassium salt of ocgudecenyl succinic acid were added to the paste oil of Example 1.

The same operation as in Example 1 was performed using the oil n1 composition. The results are shown in the table.

It can be seen from Table 3 that by using the oil having the composition of the present invention, antistatic properties and abrasion properties are improved, and thread breakage is reduced.

Example 3 Nylon 6 thread 12' with the composition shown in the table ■? 6 emulsion oil was applied. The main components in Table 9 (■) consist of 60 parts of mineral oil and 40 parts of oleyl alcohol EO adduct; It is a mixture of decenyl succinic acid and salt (b) at a ratio of 1/1.It was applied in the same manner as in Example 1 to obtain a drawn yarn of 70 denier/24 filaments.The oil content was 0.75% by weight. The results of evaluation of control] r, strength, adhesion, abrasion resistance, bIr, and thread breakage at Nakatoki are also shown in Table 1.
