Abstract

PURPOSE: To obtain a functional knitted product having excellent elasticity, antimicrobial properties and electromagnetic field-shielding properties, by constituting knitting texture from silvered yarn. CONSTITUTION: This knitted product useful for a human body having both excellent antimicrobial and electromagnetic wave-shielding effects is obtained by using silvered yarn, double yarn of the silvered yarn and organic fiber yarn, twisted union yarn composed of the silvered yarn and the organic fiber yarn, and knitted yarn such as covering yarn composed of the silvered yarn as core yarn.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional knit product which protects the human body from electromagnetic waves and microorganisms and molds existing in the living environment.

[0002]

2. Description of the Related Art Heretofore, as electromagnetic wave shielding fiber products, there have been known ones in which a woven fabric is metal-plated, and one in which metal fibers or organic fibers are woven or woven with metal-plated fibers plated with copper or nickel. There is. Also,
As the antibacterial fiber product, there are known antibacterial fibers made by binding an antibacterial agent to a fiber by a chemical reaction, adhering it with a resin processing, or spinning the solution containing an antibacterial agent. ing.

[0003]

Among those described in the prior art, the one in which the fabric is metal-plated has poor stretchability because the intersection point of the warp yarn and the weft yarn is adhered by the plating,
Further, if the intersection is rubbed due to wearing or the like, the plating is likely to be damaged and the shield effect is likely to be lowered.
Woven or knitted metal fibers have a higher specific gravity than ordinary fibers, which makes the product heavier,
There was a problem of lack of elasticity and flexibility. When metal-plated fiber is woven, the above problems do not occur and it is an electromagnetic shielding fiber product with excellent elasticity, but nickel plating cannot be expected to have antibacterial properties, and copper plating does not have antibacterial properties. However, there was a problem that the durability of rust and plating was lacking.

An object of the present invention is to provide a functional knit product having excellent stretchability and having both antibacterial property and electromagnetic wave shielding property.

[0005]

In order to achieve the above object, an antibacterial / electromagnetic wave shield knit product of the present invention is a silver-plated yarn, a straight-aligned yarn of silver-plated yarn and organic fiber yarn, a silver-plated yarn and organic fiber yarn. Is a knitting yarn in which a knitting structure is composed of a covering yarn of silver-plated yarn and organic fiber yarn, or a composite yarn of silver-plated fiber and organic fiber.

[0006]

[Function] Since the silver-plated fiber is as conductive as a metal and is antibacterial due to the action of silver ions, the above knit product has excellent elasticity, shields electromagnetic waves, and is resistant to microorganisms and molds existing in the living environment. Can suppress the breeding of.

[0007]

[Example] Silver plated nylon filament yarn 50D / 10F (trade name: X-static) made by Sauquit Industries Inc. and worsted yarn 2/48 are aligned and combined, and the structure is rubber knitted with a computer-controlled flat knitting machine. , The knitting density is the value of the dial gauge
It was organized under the conditions of 12.0. The electromagnetic wave shielding property and antibacterial property of this knitted fabric were measured. The electromagnetic wave shielding property is measured by the Advantest method using an evaluation system consisting of Advantest's spectrum analyzer with tracking generator (R3361A) and shield material evaluator (TR17301A). did. The results are shown in Table 1. For antibacterial properties, pour river miscellaneous bacteria into a standard agar medium, put it in a petri dish, embed this knitted fabric immediately before solidification, and after 37
After incubating in an incubator at ° C for 24 hours and culturing, the presence or absence of inhibition circle formation was examined. As a result, antibacterial activity was observed.

[0008]

[Table 1]

[0009]

Since the functional fiber product of the present invention is a knit, it has excellent stretchability, and since it has a net structure made of conductive silver-plated fiber similar to metal, it has an electromagnetic wave shielding effect, especially from OA devices such as personal computers and word processors. Shows a high shielding property in the frequency range of electromagnetic waves of 300 MHz or less,
It can cut electromagnetic waves by 90% or more. In addition, the silver-plated fiber has an antibacterial property due to the action of silver ions, so that it has an antibacterial effect without using an antibacterial treatment or an antibacterial fiber.
