The present invention not only absorbs sweat well when used as a yarn for clothing, especially a sports garment, and also has a property of easily drying the absorbed sweat (hereinafter referred to as "absorption quick drying") and anion generating performance which has a good effect on human health. An excellent multifilament (yarn).

As the standard of living improves recently, the demand for clothing with various functionalities is expanding. In other words, there is a need for clothing having not only simple physical and chemical durability but also sweat absorption quick drying and health promotion functions. Conventionally absorbent cotton yarn or cotton / polyester blend yarn has been mainly used as a garment yarn, but when the sweat is much, the yarn contains a lot of sweat, so it is not only wet and cold but also the clothes are wound around the body and sticky. There was a problem with no negative ion generating performance.

Meanwhile, US Pat. No. 4,470,407 proposes a polyester mold-shaped cross-section yarn having a shell-like cross section as shown in FIG. 4 to improve the water diffusibility of yarn as a prior art for improving sweat absorption and dryness. -7736 proposes a sectional cross-section yarn in which three to five spherical protrusions are formed at equal intervals as shown in FIG. The conventional release section yarns have a problem that only two to five protrusions serving as a passage for discharging sweat are insufficient in quick absorption and dryness, and there is a problem that the negative ion generation performance is not provided.

Meanwhile, Korean Patent Laid-Open Publication No. 2002-71522 proposes a sectional cross-section yarn in which six spherical protrusions are formed symmetrically as shown in FIG.

On the other hand, as a conventional technique for imparting anion generating performance to the fiber, a method of adding or coating anion generating material in the fiber is widely used, but in this case, the amount of anion is reduced after washing 10 times or more, that is, the washing resistance is bad. There was a problem of lack of sweat drying.

It is an object of the present invention to provide a yarn (multifilament) which is excellent in absorbing quick drying and anion generating performance at the same time to solve such conventional problems.

The present invention forms a cross-section of the monofilaments constituting the yarn (multifilament) to form a symmetrical form of six spherical protrusions as shown in FIG. By dispersing and containing, it is intended to give anion generating performance to the multifilament without deterioration of operability.

The multifilament of the present invention for achieving this problem is composed of (i) monofilaments of thermoplastic resin, (ii) the monofilaments are six spherical projections based on the long axis length (L ₁ ) of the monofilament cross section (2) Anion-generating materials having symmetrical cross-sections formed symmetrically, two on the upper surface, two on the lower surface, one on the left side, and one on the right side. It is characterized by containing 0.3 to 1.0% by weight.

Hereinafter, the present invention will be described in detail with reference to the drawings.

First, the present invention is a multifilament composed of monofilaments of thermoplastic resins. The cross section of the monofilament is symmetrically formed six spherical projections of different sizes as shown in FIG. More specifically, the cross section of the monofilament is symmetrical six spherical projections on the upper surface, two on the lower surface, one on the left side, one on the right side based on the long axis length (L ₁ ) of the monofilament cross section Is formed by enemy. It is preferable that the ratio of the short axis length (L ₂ ) of the monofilament cross section to the short axis width (D ₁ ) of the monofilament cross section is 1.0 to 4.0. When the L ₂ / D ₁ ratio is less than 1.0, the sweat absorptive quick drying may be lowered. When the L ₂ / D ₁ ratio is greater than 4.0, the sweat absorptive fast drying and operability may be reduced.

In addition long-axis length of the monofilament cross-section (L ₁₎ / shortening of the monofilament cross-section (L ₂₎ ratio is preferably from 1.0 to 4.0. If it is out of the above range, the operability and the quick drying rate may be lowered.

In the present invention, as the thermoplastic resin, polyamide, polyester, or polyacryl may be used, and more preferably, hydrophobic polyester is used.

The multifilament (yarn) of the present invention is very excellent in hygroscopicity because the six projections of different sizes serve as a passage for quickly discharging the sweat emitted from the human body to the outside. In addition, the multifilament (yarn) of the present invention has a very large surface area in contact with the atmosphere, which is very excellent in the property (fast drying) to quickly evaporate the sweat discharged to the outside into the atmosphere.

In addition, the multifilament (yarn) of the present invention can prevent the phenomenon of clothing wrapped around the body even when a lot of sweat is discharged due to the small contact surface with the human body is excellent in wearing comfort. The multifilament (yarn) of the present invention may be used alone or in combination with cotton or polypropylene yarns, mainly for the manufacture of garments such as jackets.

On the other hand, the multifilament (yarn) of the present invention contains an anion generating material having an average particle diameter of 1㎛ or less 0.3 to 2.0% by weight relative to the total yarn weight.

The anion generating material is tourmaline, charcoal, porous ceramics such as elvan, photocatalyst and the like, more preferably tourmaline.

The anion generating material generates anion in the air that has a blood purification effect, a neurostable effect, an autonomic nervous system, an immune strengthening effect, and the like in the human body.

When the average particle diameter of the anion generating material exceeds 1 micrometer, dispersibility worsens and a spin pack pressure rises significantly and operation property (full-drum rate) falls significantly.

On the other hand, when the content of the anion generating material in the yarn exceeds 2.0% by weight, the dispersibility decreases, the spin pack pressure is rapidly increased and the cutting is more deteriorated. Can't get it.

The multifilament of the present invention can be produced through the process as shown in FIG. 1 is a process schematic diagram of producing a multifilament of the present invention.

Specifically, the thermoplastic polymer chip (hereinafter referred to as the "master batch chip") to which the anion generating material is added while supplying the thermoplastic polymer chip to the extruder 3 through the thermoplastic polymer chip conveying pipe 1 is called a side feeder. (2) is supplied to the extruder (3) together. Subsequently, the thermoplastic polymer chip supplied from the extruder 3 and the thermoplastic polymer chip (master batch chip) to which the anion generating material is added are melted and mixed together.

Subsequently, the molten polymer is melt-spun through a spinneret 4 having a cross section as shown in FIG. 3, and then cooled by a cooling chamber 5, and then passed through a focusing guide 6 to the first gourd roll 7. The multifilament of the present invention can be produced by stretching between the second gouge rolls 8 and then winding up with a winding machine 9.

It is preferable that the temperature of the 1st gourd roll 7 is about 85 degreeC, and the rotational linear speed is about 1,500 m / min.

It is preferable that the temperature of the 2nd goth roll 8 is about 123 degreeC, and the rotational linear velocity is about 4,300 m / min.

The winding speed of the winder 9 is preferably about 4,200 m / min.

However, in the present invention, the linear linear velocity and temperature of the first gouge roll 7, the second gouge roll 8, and the take-up machine 9 are not particularly limited.

At this time, rather than directly supplying the anion generating material to the extruder (3) to manufacture the master batch chip as described above and to supply it to the extruder (3) through the side feeder (2) of the anion generating material It is more preferable for dispersibility and operability.

The present invention has excellent operability and has a full-dull rate of 95% or more.

The multifilament of the present invention has an anion value of 300 to 1,000 pieces / cc measured by an ion tester (COM-3010) manufactured by COM SYSTEM of Japan.

In addition, the multifilament of the present invention has a time (drying time) of 20 to 40 minutes until 0.05 ml of water in the yarn is completely dried.                     

In the present invention, the operability and various physical properties of the yarn were measured (evaluated) as follows.
