Description

[Detailed description of the invention] The present invention relates to a spinning oil for polyester fibers.

Polyester fibers are spun in large quantities either alone or in blends with comb, rayon, lintel, wool, etc. In recent years, the spinning industry has seen an urgent need to improve spinning efficiency and save labor in order to reduce spinning costs. As the speed of spinning machines increases, there is a strong desire for a spinning oil that is compatible with this.

As the speed of spinning machines increases, troubles are more likely to occur due to the generation of static electricity, an increase in scum that accumulates on the fibers H and Jff1 of the spinning machine, and troubles when the number of windings on rollers increases. The scum that falls off from the fibers and accumulates can cause tube clogging in the coiler and winding up on rollers, and significantly reduce the confectionery properties. Regarding the winding of rubber rollers, it is important to note that not only the accumulation of scum and the stickiness of the oil agent may cause the winding to increase, but also the fact that the surface of the roller becomes dry as described below. Trace wrapping must also be reduced.

Rubber rollers are generally surface treated with concentrated sulfuric acid or other chemicals to reduce wrapping, but after several months of spinning, the treatment effect is lost and the surface of the rubber roller becomes untreated, the so-called untreated state. As a result, wrapping of the rubber roller increases, and wrapping increases even more in a high humidity atmosphere. For this reason, it is necessary to replace the rollers, but as the speed increases, the replacement cycle has to become shorter, and in the roving and spinning processes where the number of reeds and spindles is extremely large, replacing the rollers increases the spinning cost considerably. Therefore, even if the surface treatment effect of the roller decreases, a spinning oil with less i adhesion is strongly desired even if it is attached to an untreated rubber roller.

In order to improve cylinder efficiency and save labor, it is of course necessary to reduce the scum and roller wrapping mentioned above, and to completely improve the coil linking properties of the sliver that is spun in the carding and filament processes8? And'y ny,
(#1fi) [It is also important to increase the number of Nuraibano storms that can be contained. Normally, when the tj can or the can is near full, the coiling becomes disordered and no more sliver can be accommodated, but if the coiling does not become disordered, it becomes possible to accommodate more sliver, which increases production efficiency. Therefore, there is an increasing demand for a spinning oil that has good coil link retention even in 2b, in a state where the contact pressure between the fiber and metal is high in the target can.

By reducing the pulling strength of the sliver, it is possible to reduce the number of twists during spinning, thus increasing the production efficiency, so it is possible to increase the pulling strength of the sliver without causing draft irregularities. is also effective in improving efficiency.

1, the temperature and humidity of the atmosphere in each spinning process) 5 has a great effect on spinning properties, and when the layer temperature reaches normal, cylinder winding in the carding process and rubber roller winding in the filament, roving, and spinning processes. conversely, when the humidity is low, problems such as the generation of n-electricity, insufficient conjugation between fibers, and clogging of the bottom (metal) roller winding tube during the filament process are likely to occur. For this reason, in order to maintain good spinning conditions, it is necessary to control temperature and humidity throughout the seasons, and in fact, many spinning factories are equipped with humidity control equipment to maintain a constant temperature and humidity. However, it is difficult to completely control the temperature and humidity inside a large textile factory, and operating temperature and humidity control equipment costs a lot of money. There is a strong demand for a spinning lubricant that provides good spinning performance even against recoil.

Conventionally, oils containing alkyl phosphate esters (Nk) as the main component have been widely used as oils for polyester/l/aerosols, but in practice, the most commonly used oils are lauryl alcohol phosphate esters, The number of carbon atoms in the alkyl group is at most 16, and alkyl phosphates having 18 or more carbon atoms have been practically ignored.

For example, alkyl phosphate esters with a large number of carbon atoms, such as alkyl phosphate esters with a carbon number of 18 or more, have poor water bathability and are inconvenient to use. This is thought to be because it was not expected to achieve particularly superior effects compared to the previous one.

Conventional polyester fiber treatment agents containing alkyl phosphate esters as the main component have the advantage of less roller wrapping under moderate temperature and humidity conditions; At low temporary properties, the spinnability is highly dependent on 1M humidity, such as poor antistatic properties and poor fiber cohesiveness.
Moreover, when applied to open-end MvJ, there are still drawbacks such as insufficient scum prevention. Furthermore, the rubber rollers that have lost their surface treatment effect tend to get wrapped around more often, and in direct humidity, the adhesiveness of the old I1J increases due to moisture absorption, resulting in more scum accumulation and roller wrapping. .

Japanese Patent Publication No. 57-37707 discloses a spinning oil containing an alkyl phosphate ester, a polyoxyethylene alkyl ether (N-pur) having a specific number of added moles of ethylene oxide, and a fatty acid ester in a specific ratio. This spinning oil uses an alkyl phosphate that reduces the amount of scum that gets wrapped around the combing roller, a specific nonionic surfactant that reduces scum generation, and a fatty acid ether that is compatible with both of them. The purpose is to prevent wrapping. However, this spinning oil is essentially a conventional alkyl phosphate ester with a carbon number of 12 to 16, and the generation of scum and its wrapping around the rollers are completely identified as alkyl phosphate esters and nonionic surfactants. It would be better if the problem could be solved by blending at the blending ratio of . It is true that stearyl phosphate is mentioned in the above-mentioned publication, but its usage weight cannot exceed 60 M%. Therefore, it is not affected by seasonal fluctuations in temperature and humidity, and the effect of preventing wrapping around the rice processing rubber roller cannot be obtained.

The present invention has less roller wrapping during the spinning process even when it is humid, less scum generation, and improved coiling properties of the sliver spun in the sword and drawing processes, making it possible to increase the capacity of the can. To provide a spinning oil agent which improves production efficiency by completely reducing the number of twists that are slightly dull by increasing the pulling strength of the sliver, and at the same time imparts excellent spinning properties regardless of temperature and humidity. .

That is, the present invention contains one or more of Kyowa's higher alcohols having 18 to 20 carbon atoms in an amount of 50M weight or more, and the average carbon number of all the alkyl groups is in the range of 17 to 21. 60% gold salt of alkyl phosphate obtained by neutralizing a phosphoric acid ester of a higher alcohol having 111 chains and/or 111 chains with an inorganic alkali hydroxide.
This invention relates to an oil agent for treating polyester fibers containing more than % by weight.

The metal salt of alkyl phosphate used in the present invention contains 50% or more of one or more saturated higher alcohols having 18 to 20 carbon atoms, and the average carbon number of all the alkyl groups is greater than 17. Phosphorylation degree (Durham number of phosphorus atoms bonded to 1 mole of alcohol) obtained by phosphoric acid esterification of higher alcohols having direct rigidity or /2 and side order in a range smaller than 21 0.6 ~ It is obtained by neutralizing the acidic alkyl phosphate ester of 1.2 with an inorganic alkali hydroxide.

The raw material alcohol used for the alkyl phosphate ester of the present invention includes, for example, nutaryl alcohol, inutearyl alcohol, nonadecyl alcohol, eicosyl alcohol, etc., and these may be used alone or as a blend. Also, carbon number is 18~
20 and an alcohol having 17 or less carbon atoms, for example, even if it is an alcohol containing a tera such as cetyl alcohol, the alcohol must meet the above requirements, that is, the alkyl group having 18 or more carbon atoms should account for 50% or more. It can be used as long as it is mixed with alcohol, whether it is a blend or a naturally derived alcohol, such as reduced beef tallow alcohol.

1. Even alcohols containing 18 to 20 carbon atoms and 21 or more carbon atoms, such as t-hatocyl alcohol, can be used as long as they meet the above requirements. When containing an alcohol having 17 or less carbon atoms, it is desirable that the alcohol having 18 to 20 carbon atoms is saturated. 1. Unsaturated alcohols, such as oleyl alcohol, lylyl alcohol, lylunyl alcohol, etc., can be blended in an amount of 50% or less, preferably 30% or less, but are derived from plants. Partially reduced alcohol can also be used as long as it meets the above requirements by 1tj. When the average carbon number is greater than 21, the solubility in water becomes poor, making it difficult to uniformly feed the fibers. f. If the saturated alkyl content is less than 50%, the viscosity of the oil at high m1 will be low, causing an increase in scum and roller wrapping.

In addition, the alkali metal of the alkyl phosphate metal salt is lithium, sodium, potassium, etc., but potassium is particularly good from the viewpoint of antistatic properties, and the degree of neutralization is determined from the viewpoint of antistatic properties. 60-10 acid groups
0% equivalent weight, preferably 70-100% equivalent weight, 60
If it is lower than % equivalent, the antistatic properties will be poor.

The furkyl S-acid Nether metal rod synthesized as described above maintains its properties even under high temperature and high humidity conditions, and has very low stickiness due to moisture absorption, so that the accumulation of scum is significantly reduced. In addition, it has a special ridge that has extremely little winding at both temperatures, not only on surface-treated rubber rollers but also on untreated rubber rollers, and is insensitive to temperature and humidity. 'J? It is excellent as a main component of textile oil. The sticking of rubber rollers, especially untreated rubber rollers, does not necessarily correlate with the level of tackiness of the oil, and the reason why the alkyl phosphate metal salt of the present invention hardly sticks is simply that the tackiness is low. In addition, the interaction between the oil and rubber is also closely related.

In the present invention, the alkyl phosphate ester salt is used in an amount of more than 60% by weight, preferably 65 to 90% by weight, based on the total solid content of the oil agent. Of course, you can use 100%.

If it is used at a concentration of 60% or less, it will not be suitable for cutting because the drawbacks of other ingredients will appear.
