Description
The present invention relates to a sheath-core type synthetic fiber, and more specifically, to disperse and contain germanium in the core portion (C), while having an excellent far-infrared emission function and an easy weaving preparation process and a weaving process. In addition, the present invention relates to a sheath-core synthetic fiber having no limitation in color upon dyeing.
As a synthetic fiber having a function of emitting far infrared rays (hereinafter referred to as "far infrared ray emitting yarn"), as described in Korean Patent No. 10-0485505, it is for emitting far infrared rays such as char, tourmaline, germanium, etc. in the synthetic polymer constituting the yarn. Yarns containing inorganic materials evenly dispersed and contained have been mainly used.
In other words, the conventional far-infrared emitting yarn is a structure in which inorganic materials emitting far-infrared rays, such as tourmaline or the like, are uniformly dispersed and contained throughout the yarn surface, and the synthetic polymer containing the inorganic material is evenly dispersed and contained in the conventional synthetic fibers. It was prepared by spinning with a spinning device.
However, the conventional far-infrared emitting yarn, as described above, has an inorganic material on the yarn surface because the inorganic material is evenly dispersed throughout the yarn cross section.
As a result, the conventional far-infrared ray emitting yarn has a problem that the surface friction coefficient is increased, so that a lot of trimming occurs during the weaving preparation process or the weaving process.
In addition, the conventional far-infrared emitting yarn containing char particles as the far-infrared emitting material has a problem that it is difficult to express various colors during dyeing due to the intrinsic black color of the charcoal particles.
The present invention is to solve the various problems of the conventional far-infrared emitting yarn, specifically, it is possible to express a variety of colors by dyeing, the surface friction coefficient is low, the workability of the weaving preparation process or weaving process is improved, far infrared generation The present invention seeks to provide a sheath-core synthetic fiber having excellent effects.
In order to achieve such a problem, in the present invention, the cross-sectional shape of the yarn (synthetic fiber) is a sheath-core type, and the germanium particles emitting far infrared rays are dispersed and contained only in the core portion (C). It is characterized by.
More specifically, the sheath-core synthetic fiber according to the present invention, as shown in Figures 1 to 2 at least one core portion made of a synthetic polymer containing 0.5 to 3.0% by weight of germanium particles relative to the total weight ( C) and a synthetic polymer is made of a sheath portion (S) surrounding the core portion (C).
1 to 2 are cross-sectional views of sheath-core synthetic fibers according to the present invention, in which C represents a core part, and S represents a sheath part.
The synthetic polymer forming the core part C and the sheath part S may be polyester, polyamide, polypropylene, or the like, and the kind of the synthetic polymer of the core part C and the kind of the synthetic polymer of the sheath part S may be the same. It may be different from each other.
The cross-sectional shape of the core portion C is circular, and the cross-sectional shape of the sheath portion S is shaped like circular or triangular.
The core portion (C) is one or two or more, the content of the germanium particles contained in each core portion (C) is 0.5 to 3.0% by weight relative to the total weight of the core portion (C).
When the content of the germanium particles is less than 0.5% by weight, the far-infrared ray emission effect is lowered, and when the content of the germanium particles is more than 3.0% by weight, there is a concern that the yarn radioactivity is lowered.
The sheath-core synthetic fiber according to the present invention can be produced using a conventional composite spinning device for spinning the sheath-core composite fiber. Specifically, a composite polymer containing dispersed and contained germanium is supplied to the core port-forming supply port of the composite spinning device, and a common synthetic polymer containing no germanium is supplied to the sheath-portion supply port to complex spun them.
A master batch chip of a synthetic polymer in which germanium is dispersed and contained may be supplied to the supply port for forming the core portion.
The present invention also includes a fabric comprising the sheath-core synthetic fibers described above.
The present invention has an effect of emitting far infrared rays, having a low surface friction coefficient, facilitating a weaving preparation process and a weaving process, and having a colorless effect during a dyeing process.
Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.
However, the present invention is not limited by the following examples.
Example One
In the composite spinning device for producing sheath-core composite fiber, germanium-free polyester resin is supplied as a synthetic polymer for forming sheath parts, while germanium is dispersed by 1.5% by weight based on the total weight, and the polyester resin containing core resin is formed for core parts. Sheath-core synthetic fibers were prepared by compound spinning, stretching and winding them in a cross-sectional shape as shown in FIG. 1.
As a result of weaving a twill fabric using the sheath-core synthetic fibers thus prepared as warp and weft yarns, the cut ratios in the weaving preparation process and the weaving process were 40% lower than those of Comparative Example 1 described later.
Example 2
A sheath-core synthetic fiber was prepared in the same manner as in Example 1 except that the cross-sectional shape of the sheath-core synthetic fiber was changed as shown in FIG. 2.
As a result of weaving a twill fabric using the sheath-core synthetic fibers thus prepared as warp and weft yarns, the cut ratios in the weaving preparation process and the weaving process were 35% lower than those of Comparative Example 1 described later.
Comparative Example One
To the spinning device for preparing synthetic fibers other than the composite fiber, germanium was dispersed in 1.5 wt% (relative to the total weight) and supplied with a polyester resin, which was spun, stretched and wound to prepare a far-infrared emitting synthetic fiber.
As a result of weaving the twill fabric using the far-infrared emitting synthetic fibers thus prepared as warp and weft yarns, the cutting rate in the weaving preparation process and the weaving process was 40% higher than that of Example 1.
On the other hand, the cut rates of Example 1, Example 2 and Comparative Example 1 were all measured and compared under the same conditions.
1 to 2 are cross-sectional views of sheath-core synthetic fibers according to the present invention.
