Polyolefin Synthetic Fiber Treatment Agent

The present invention relates in particular to a treatment agent for polyolefin fibers, and more particularly to a polyolefin-based synthetic fiber treatment agent that improves the binding and antistatic properties in the spinning process.

Synthetic fibers, especially polyolefin synthetic fibers, have a significantly lower coefficient of static friction between fibers than synthetic fibers such as polyester or nylon, resulting in poor convergence and lorlor winding due to friction and bulkiness during the stretching process. Or, in the spinning process, web cutting, fiber breakout, and fly phenomena occur and are extremely hydrophobic, so the generation of static electricity is remarkably high. The deficiency causes severe coiling foam or roller trimming, resulting in reduced productivity and product quality.

In order to solve the above problems, conventionally, an emulsion containing a large amount of alkyl phosphate metal salt as an antistatic agent is used, but the focusability is good, but the antistatic property is deteriorated.

In addition, as antistatic agents commonly used in the production of olefinic fibers, quaternary ammonium salts such as trimethyl lauryl ammonium chloride, triethyl polyethylene stearin ammonium methosulfate, tributyloctyl ammonium nitrate and lauryl Although phosphate metal salts are used, most of them have a drawback in that the oil film is destroyed by various friction agents and thus the antistatic property is weakened.

It is an object of the present invention to produce a polyolefin-based synthetic fiber, which has to be equipped with olefin-based yarns in the stretching and spinning process, so that there is little dropout, there is no static electricity, it is to be uniformly attached, and good concentrating theory is provided.

Therefore, an antistatic agent and a focusing agent capable of achieving this purpose are required, and suitable antistatic components require a function to impart antistatic properties to fibers even under high humidity and low humidity. As the ammonium phosphate salt type, the most preferred is a polyoxyethylene alkylphenyl effer type having excellent oil film strengthening ability in order to improve connectivity.

Therefore, the present invention focuses on the required properties of the treatment component, and prevents the coiling and dropping by the rubber roller in the stretching and spinning process, to obtain a good coiling foam, yellowing and rust due to heat treatment, and also has a small effect After earnestly examining the development of the present invention, the present invention has been reached.

The present invention is 50 to 70% by weight of an antistatic agent component consisting of 3 to 30% by weight of the quaternary ammonium phosphate salt, 70 to 97% by weight of a saturated alkyl phosphate ester alkali metal salt having 75 or more carbon atoms of at least 18 alkyl groups, 60 to 80% by weight of alkyl groups of 8 to 9 polyoxy ethylene alkylphenyl alkylphenyl ethers (addition of 3 to 15 moles of ethylene oxide), 12 to 18 polyoxy ethylene alkylamine ethers of alkyl groups (adding 8 to 12 moles of ethylene oxide) 20 30 to 50% by weight of the binder component, which is in the ratio of 40 to 40% by weight, and the amount of the treatment agent to the polyolefin-based synthetic fiber drawn yarn is usually 0.15 to 0.30% by weight, preferably 0.25 to 0.30% by weight. It is a processing agent of polyolefin synthetic fiber.

If the quaternary ammonium phosphate salt and the saturated alkyl phosphate alkali metal salt are 70 wt% or more, the droppings increase due to the adhesion of the treatment agent, and at 50 wt% or less, the coiling foamability is poor due to the antistatic property of the polyolefin yarn. Thereby inhibiting process passability.

Meanwhile, the nonionic surfactant used in the present invention is 30 to 50 wt% mixed with polyoxy ethylene alkylphenyl efer and polyoxy ethylene alkylamine ether.

If it is more than 50% by weight, the drafting property is poor, and if it is less than 30% by weight, the focusing property is deteriorated.

Since the polyolefin fibers are nonpolar, they have no affinity for the treatment agent and are hydrophobic and generally unsuitable for using a hydrophobic treatment component and obtaining a satisfactory treatment agent. The present invention will be described in detail with reference to the following Examples.

EXAMPLE

When the composition ratio of the treatment agent used in the present invention is as shown in Table 1, the polyolefin yarn was prepared at a surface temperature of 70 to 80 ° C., a set machine of 160 to 170 ° C., and a draw ratio of 3.5 to 4.0 by one undrawn yarn having a drawing speed of 120 m / min.

Table 2 shows the results of the electrical resistance value, friction band voltage, roll winding, measurement of adhesion, yellowing, and coiling foam.

TABLE 1

Here, the measurement evaluation of the final product polyolefin company is as follows.

(1) Measurement of electric resistance

0.9% (effective weight%) of the Example was given with respect to olefin yarn (3 denier x 51 mm), it dried at 60 degreeC x 2 hours, and it was set as the test surface.

In addition, the test surface was left for 24 hours at 25 ° C. × 40% RH or 25 ° C. × 65% RH, and the respective electrical resistances were measured.

(2) evaluation of yellowing

The test surface was heat treated at 150 ° C. × 2 hours and each yellowness was evaluated by visual observation.
