(1) Fibers that have a conductive function (a>metallic fibers... They are heavy, hard, do not stretch, cannot be dyed, etc., so when fabrics are made into knitted fabrics, they impair fashionability and texture.

(b> Synthetic Ili# with metal plating...When making fabrics, J-plating is applied to prevent friction with the loom, etc.

Furthermore, when knitting, the plating layer breaks because the elongation rate of the plating layer is lower than the elongation rate of the synthetic fiber. moreover,
This fiber is a 1° (C) synthetic fiber that cannot be dyed with copper sulfide dyeing...Is it possible to dye it deep color?
There is a problem with washing resistance. .

Also, because the resistance is high, the conductive effect is not sufficient (and the electromagnetic shielding properties are poor).

(d) Organic fibers mixed with short metal fibers or metal-plated short fibers, C wet paper-made, then shredded into yarn.
...Increasing the mixing ratio of short metal fibers, etc. to improve conductivity causes a decrease in paper strength and makes it impossible to shred. M1=,
Since short metal fibers cannot be dyed, uneven dyeing can occur between them and organic fibers. Furthermore, metal short fibers are likely to fall off due to friction with twisting machines, looms, etc.;
11i fibers or parts such as the twisting machine are worn out.

(2) 91i fiber, which utilizes the heat retention function inherent in inorganic substances such as far-infrared radiation of ceramics, to enhance its heat retention function. This impairs the fashionability and texture of woven or knitted fabrics.

(b) Synthetic fibers with inorganic fillers bonded to them...When making textiles, the inorganic fillers are removed by friction with the loom, etc. Furthermore, when knitting fabrics, the elongation rate of the inorganic coating is lower than that of synthetic fibers, so the inorganic coating may break. Furthermore, this fiber cannot be dyed.

(C) Synthetic fibers mixed with inorganic noiler...
If the filler mixing ratio exceeds 10%, the fiber strength will decrease and there will be problems in spinning.

(d> Wet paper made by mixing organic fibers with inorganic short fibers or inorganized short fibers, which is then shredded and made into yarn...
・Inorganic fibers to improve heat retention! ? If the mixing ratio is increased to 1, etc., the strength of the paper will decrease and it will not be possible to shred it. Also,
Since inorganic fibers cannot be dyed, uneven dyeing occurs between them and organic fibers. Furthermore, inorganic fibers and the like tend to fall off due to friction between the yarn twisting machine and the loom, and in addition, the inorganic fibers and the like wear out parts of the yarn twisting machine and the like.

[Example] Hereinafter, a first example in which the present invention is embodied in a functional material will be described with reference to the drawings.

As shown in FIG. 1, the functional layer vJ1 of this example consists of a functional layer 2 that is a mixture of fibers that perform a predetermined function (hereinafter referred to as functional fibers) and ordinary organic fibers, and a functional layer 2 that is made of only ordinary organic fibers. It has a two-layer structure in which a reinforcing layer 3 is joined.

Functional fibers are fibers that utilize the unique characteristics of inorganic materials such as carbon, metals, and ceramics, and are made into fibrous materials that exhibit desired functions.

Functional fibers include, for example, carbon fibers, reramic fibers (including glass fibers), metal fibers, inorganic fibers, or metallized fibers made by metallizing organic fibers such as metal plating, and organic fibers with inorganic fillers. Examples include those that are glued or embedded. Depending on the characteristics of the inorganic material, these have electrical conductivity, static elimination function, magnetic shielding function,
It performs prescribed functions such as heat retention and deodorizing functions.

Further, the organic fibers mixed in the functional layer 2 and the organic fibers constituting the reinforcing layer 3 are those used for normal purposes,
For example, natural fibers such as true (Δ fiber-'X') composition fibers,
1-) Synthesis of P, PE, PET, PVA, etc. 8. Depending on the characteristics of the organic material, these fibers exhibit functions such as feel, texture, and dyeability unique to organic fibers.

Note that the functional fibers and organic fibers are all short fibers with a fiber length of 24 mm or less.

In the above-mentioned functional layer 2, a functional fiber is blended which exhibits a predetermined function depending on the purpose of the above-mentioned functional fiber. For example, as a material for electromagnetic shielding clothing, 20% or more by weight of charcoal fibers is mixed with conductive inorganic fibers. If the blending ratio of carbon fiber is less than 20%, the electromagnetic shielding effect will not be sufficient. In addition, Moketsu 1 to Sea 1 for automobiles
C is a static neutralizing material that prevents the generation of static electricity.C is a conductive fiber with an aspect ratio (length/diameter).
750 carbon fibers at a weight ratio of 2% or more, or carbon fibers with an aspect ratio of 2,000 or more are blended at a weight ratio of 1% or more. If the blending ratio of carbon fiber is less than these, sufficient static elimination effect will not be exhibited. Furthermore, as the material for the heat-retaining Surin 1 to yarn, 20% or more by weight of ceramic fiber is mixed and covered. If the blending ratio of ceramic fiber is less than 20%, sufficient heat retention effect will not be exhibited.

The reinforcing layer 3 contains heat-adhesive synthetic fibers such as PVA, PF, PP, and PET at a weight ratio of 1% or more. It assists the adhesion of layer 3, creates interfacial bullet holes, and prevents cracking of both layers 2 and 3. When the reinforcing layer 3 is made of 100% natural fibers, it is necessary to consider layer cracking.

The reinforcement layer 3 has a basis weight of 5 g/m2 or more and 15 g/m2 or more.
If it is less than 3 basis weight (CI/m) 2 (J, the thickness of the reinforcing layer 3 is difficult to maintain, and if it exceeds 15 CI/m', the reinforcing layer 3 will become too thick and the paper yarn will In this case, there may be a problem with the softness of the texture.

In the functional material 1 configured as described above, the functional layer 2
exhibits the desired function, and the reinforcing layer 3 or the functional layer 2
To improve the paper strength of a single functional material by supplementing the paper strength of the functional layer 2 itself without impairing the unique functions of the functional material. In addition, the reinforcing layer 3
In order to supplement functional layer 2 in terms of functions unique to ordinary fibers, such as good feel, texture, dyeability, etc., functional cord material 1 is used for applications such as clothing materials in the same way as ordinary woven and knitted materials. can.

Note that instead of the functional material 1 having a two-layer structure, a functional material 11 having a three-layer structure as shown in FIG. 2 may be used. In the same functional layer vJ11, the functional layer 12 is sandwiched between a pair of reinforcing layers 13. In this way, the reinforcing layer 13 protects the functional layer 12 from both sides in the thickness direction, and the functional material The strength of the 11-day paper will further improve. In addition, the functional layer 12 is not exposed to the outside and impairs the feel, texture, dyeability, etc., and the functional material 11 has the same feel, texture, and dyeability as ordinary woven and knitted materials. Demonstrate.

In addition, in the functional materials 1 and 11, the reinforcing layers 3 and 1
Instead of 3 being made of organic fibers, it may be in the form of a film.

Next, a second embodiment in which the present invention is embodied in a slit yarn for woven or knitted fabrics using the above-mentioned functional cord materials 1 and 11 will be described with reference to FIGS. 3 to 8.

The Surin 1-V-n 21 of this embodiment has the above-mentioned functional cable material 1,
11 is cut into pieces and subjected to twist loading. As for the twisting method, for example, the method J shown in FIG. 3 is adopted in the case of the functional cable material 1 having a two-layer structure. In this twisting process, the functional material 1 that has been roughly shredded is folded into thirds in the width direction so that the functional layer 2 is on the inside, and then subjected to a normal twisting process to form the slit yarn 21. Further, as shown in FIG. 4, twisting is performed in the same manner as to form a cover yarn to form slit lanes 22 so that the functional layer 2 is on the inside. With these slit yarns 21 and 22 d3, only the reinforcing layer 3 is exposed to the outside to protect the functional layer 2, preventing the functional layer 2 from being exposed to the outside, and preventing the functional fibers from the functional @2 from being exposed to the outside. prevent it from falling off. Therefore, the woven or knitted fabric using these slits t'-ons 21, 22 has a functional layer 2.
In addition to fully demonstrating its unique functions, it also exhibits the same good texture, texture, and dyeability as ordinary fiber materials.

In addition, as shown in Figure 5, two pieces of functional material 1 are cut into pieces.
The functional layers 2 may be joined so that they are facing each other, and then subjected to a normal twisting process to form yarns 1 to 23.

In the functional layer +111 of the three-layer structure, as shown in Figs.
Same as yarns 25 and 26. In this case as well, the functional layer 12
is not exposed to the outside, so the above Surin 1 ~ Yarn 21 ~
