KR0142070B1 - Emulsion composition for polyamide fiber - Google Patents

Abstract

The present invention relates to an emulsion composition which is used for tanning before stretching the warp of polyamide fibers, in particular polyamide fibers.

The conventional emulsion composition is easily deteriorated and tarned under high temperature, so it is deposited on the heating plate or contaminated the fiber and weakened the working environment by fuming and caused uneven heat transfer to the fiber, resulting in non-uniformity of the product.

The present invention is an emulsion composition containing a relatively high content of fatty acid esters instead of reducing mineral content and containing an antistatic agent, 10 to 20% by weight of mineral oil, 12 to 17% by weight of polyethylene glycol fatty acid ester and 1 to 1 of alkalsulfonate sodium salt. 3 wt% and the like.

The arc slant treated with the present invention was less fumed, had good antistatic properties, and had excellent weaving properties.

Description

Emulsion composition for polyamide fiber

The present invention relates to an emulsion composition used in tanning for the purpose of significantly improving the production operation rate by improving the post-processing and arc workability before melt spinning and stretching the polyamide fiber.

In general, the characteristics of the spinning oil required for the inclined filament yarn should have good compatibility with the hose at the time of the call, and the heat resistance property is required to suppress the generation of static electricity due to the speed of the call and the work environment.

In general, the fiber treatment agent used in the process for producing a synthetic fiber is composed of a component for preventing static electricity and a component that gives flatness.

For example, cationic surfactants of ionic or ammonium salts, such as alkylsulfonate salts and higher fatty acid sulfides, are generally used for antistatic purposes, and mineral oil, higher fatty acid esters, etc. are used for providing smoothness.

However, most textile treatment agents are organic materials, so if they are treated for a long time at a high temperature of around 200 ° C near the melting point of thermoplastic synthetic fibers made of organic synthetic high-branched materials, they will decompose, discolor, or generate tar and lose weight due to evaporation. There are defects such as fume.

Among them, anionic or cationic surfactants used for preventing static electricity and nonionic surfactants used as nucleating and emulsifying agents used as smoothing agents are deposited or heated on a heating plate because they are easily deteriorated and tarned under high temperature. It contaminates, deteriorates the working environment due to smoke and causes uneven heat transfer to the fibers to be treated, resulting in deterioration of product and deterioration of workability.

Therefore, in the present invention, while reducing the content of mineral oil in the leveling agent components, the content of fatty acid esters was relatively increased in order to maintain the existing performance and enhance smoothness and heat resistance.

In addition, by using an antistatic agent in order to reduce the generation of static electricity during the call work solved the problem of workability at the time of call.

Hereinafter, the present invention will be described in detail.

The present invention is 10 to 20% by weight mineral oil, 45 to 55% by weight alkyl alkylate (MW, 500), 5 to 10% glycerin dioleate, 12 to 17% by weight polyethylene glycol fatty acid ester, polyoxyethylene lauryl ether 5 ~ 7% by weight, alkylimidazoline 1-3% by weight, alkyl phosphate salt 5 ~ 6% by weight, alkyl sulfonate sodium salt 1 ~ 3% by weight of the emulsion composition for polyamide fibers. Has 1 to 8 carbon atoms)

In the present invention, when the mineral fiber and the alkyl alkylate (MW, 500) is less than the lower limit, yarn operation is poor due to smoothness and poor connectivity, and poor manufacturing performance is low, resulting in low production availability. If the upper limit is exceeded, the heat resistance is poor, and the smoke in the dry drying cylinder causes a problem of weakening the working environment.

When glycerin monooleate, polyethylene glycol fatty acid ester and polyoxyethylene lauryl ether are less than the lower limit, the emulsification force is deteriorated, and the emulsion stability and uniform adhesion deteriorate. Poor production rate If the alkylimidazoline, alkylphosphate, or alkylsulfonate sodium salt is less than the lower limit, the generation of static electricity is increased. If the alkylimidazoline, alkylphosphate sodium salt is less than the upper limit, the friction between yarn and fiber is increased due to increased friction between fibers and metals, and yarn damage. It decreases the elongation of filament of arc adverbs.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.

[Examples 1-3 and Comparative Examples 1-4]

The composition ratios of the emulsions used in Examples and Comparative Examples are shown in Table 1, the emulsion of Table 1 was slowly stirred sufficiently with hot water at 30 ° C. to form an emulsion solution, and then the emulsion was added to a normal oil roller oiling method. Was treated to 24 polyamides filament wound at a speed of 1000 m / min, and this undrawn yarn was stretched three times to obtain a stretched yarn of 70 denier.

After spinning and applying the spinning oil having the composition shown in Table 1, the acrylic spray agent for the water spray weaving machine (WJL) was used, and the weaving and weaving were performed.
