は粒子の凝集が起り易く、不都合なことが多い。The particle size of the particles having far-infrared radiation characteristics is preferably sufficiently small so as not to hinder the production of far-infrared radiation core-sheath type composite fibers which are the material of the sock of the present invention. For relatively thick fibers, it is possible to use fibers with a particle size of 5 to 20μ, but usually 0.1 to 5μ, especially 0.2 to 1.5μ
The thing of a grade is suitable. On the contrary, if the particle size is 0.1 μm or less, aggregation of particles is likely to occur, which is often inconvenient.

From the viewpoint of far-infrared radiation performance, a higher mixing ratio of particles having far-infrared radiation characteristics is more preferable, while a lower mixing ratio is often preferable in terms of fiber production.

ある。One of the features of the far-infrared radiation core-sheath type composite fiber which is a material of the sock of the present invention is that the core portion of the far-infrared radiation layer is covered with the sheath portion. The sheath protects the far infrared radiation layer,
The purpose of the present invention is to facilitate the production of the far-infrared radiation core-sheath type composite fiber and the sock of the present invention using the same.
That is, when the far-infrared radiation layer containing a large amount of particles having far-infrared radiation characteristics is exposed, there is a tendency that metals and guides such as spinning machines, drawing machines, knitting machines, and looms that come into contact with each other are significantly worn and damaged. , It is necessary to cover with a sheath to prevent this.

い。5 to 11 are explanatory views showing specific examples of the cross-section of the far-infrared radiation core-sheath type composite fiber which is a material of the sock of the present invention. In the figure, 1 indicates the core of the far infrared radiation layer, 2
Indicates a sheath. Since the polymer of the sheath 2 absorbs far infrared rays, it is preferable to make the thickness of the sheath 2 as thin as possible, usually 10 μm or less, preferably 5 μm or less, and particularly 2 μm or less. Figures 7, 8 and 11 show
This is an example in which the far-infrared radiation layer has a plurality of core portions 1, and the sheath portion 2 has a small thickness and the strength of the whole fiber is easily maintained by the sheath portion 2, which is preferable in many cases. 9 to 11 show examples of the composite fiber having the hollow portion 3, which is often preferable for the purpose of bringing the ceramic layer as close to the outer layer as possible.

芯部１と鞘部２に使用してもよい。As the polymer of the core portion 1 and the sheath portion 2 of the far infrared radiation layer,
A material having low far-infrared absorption in the wavelength region of 4.5 to 30 μm and high transparency is preferable, and polyethylene and polyamide, which have been widely used conventionally for clothing, are particularly preferable. This polyethylene or polyamide may be used separately for the core 1 and the sheath 2, or either of them may be used for the core 1 and the sheath 2.

吸収を防ぎ放射率を高めることができる。Polyethylene is excellent as a polymer having a high far-infrared transparency. Low-density polyethylene has a softening point of 105 ° C and a high-density polyethylene melting point of 128 ° C, which makes it somewhat inferior in terms of heat resistance and limits its use temperature, but it can be sufficiently used for heating the human body. Furthermore, polyethylene crosslinked by irradiation with radiation has excellent heat resistance (softening point of 200 ° C. or higher) and is suitable for the purpose of the present invention. Nylon 12, nylon 11,
There are polyamides such as nylon 610, nylon 612, nylon 6, nylon 66, etc. If the thickness is made sufficiently thin, absorption of far infrared rays can be prevented and emissivity can be increased.

ル状でそれ単独で、または通常繊維と混合して従来と同
様の方法で、靴下に仕上げること出来る。The composite fiber used as the material for the sock of the present invention can be produced by a well-known composite spinning method. Spinning, stretching, heat treatment, etc. can be carried out at a normal speed, and semi-oriented or fully oriented fibers can be obtained by high-speed spinning. The composite fiber having a sheath portion has a core of the far-infrared radiation layer directly spun on the nozzle,
Since it does not come into contact with guides, rollers, travelers, heating plates, etc., they are less worn and can be produced in the same process as ordinary fibers. The composite fiber can be crimped or uncrimped in the form of continuous filaments, or in the form of staples, by itself, or can be mixed with ordinary fibers to finish socks in a conventional manner.

-2〜PC-6を得た。Example 1 6-nylon having an intrinsic viscosity of 1.19 in a meta-cresol solution at 25 ° C. is used as a polymer P-1. A mixture of 30 parts by weight of γ-alumina having an average particle size of 0.6% and a purity of 99% and 30 parts by weight of polyethylene wax is added to 60 parts by weight of the powder of polymer P-1 and a mixed polymer is passed through a biaxial kneader. I got PC-1. In the same manner, knead the various kinds of powder and mix the mixed polymer PC shown in Table 1.

0d/24fである。Next, by melt-composite spinning, the mixed polymer PC-1 was compounded into the core and the polymer P-1 into the sheath, that is, into a structure as shown in FIG. 5 (volume compounding ratio 1/1), and at 270 ° C. 0.25 diameter
After being spun out from an orifice of mm and cooled and oiled,
It was wound at a speed of 0 m / min. This unstretched yarn was stretched 3.2 times at 90 ° C. to obtain a stretched yarn Y-1. In the same manner, using the mixed polymers PC-2 to PC-6 and the polymer P-1, spin drawing,
Stretched yarns Y-2 to Y-6 were obtained. Further, a stretching system Y-7 using only the polymer P-1 was obtained. The drawing system Y-1 to Y-7 has a fineness of 7

ほぼ同様に紡糸・延伸出来た。For the purpose of comparison, only the mixed polymer PC-1 was used, and an attempt was made to spin under the same conditions, but yarn breakage occurred frequently and spinning was impossible. Therefore, when the content of alumina particles was reduced to 10% and spinning was performed, some yarn breakage occurred, but spinning was possible. However, in the next twisting step, the traveler was so worn that it could not be twisted continuously for 30 minutes. In addition to the traveler, the spinning orifices in contact with the mixed polymer, the yarn guides and traverse guides of the take-up winder, and the yarn guides of the twisting machine are seriously damaged, and industrial production is considerably difficult.
Further, in the subsequent steps such as false twisting, warping, and woven / knitting steps, the damage and wear of the parts where the filaments are in contact were significant. On the other hand, the drawn yarns Y-1 to Y-6 could be spun and drawn almost in the same manner as the ordinary drawn yarn Y-7.
