Problems solved by technology

[0008] First of all, in ultra-fine metal wires or metal-plated wires, the surface changes over a long period of time or becomes black due to oxidation of bleaching agents, etc., so if these are used in fiber products, the appearance of the fiber products will be affected. Unsightly, there may be a problem of reduced antibacterial properties
In addition, since the metal parts of these ultra-fine metal wires or metal-plated wires are easily heated by infrared rays, etc., wearing fiber products containing these materials, for example, may cause low-temperature burns during infrared thermotherapy
[0009] Secondly, since the silk containing antibacterial agents will dissolve the antibacterial agents during washing, repeated washing will reduce the antibacterial properties, and there is a problem of losing antibacterial properties in a short period of time.
[0010] In addition, since carbon fiber, one of the antistatic fibers, is a black fiber, there is a problem that the possibility of use is limited from the perspective of commercial appearance, and it must be treated with chemicals in the spinning or dyeing process, and repeated washing will also cause problems. Make it a problem to prevent the loss of electrification
[0011] In addition, gauze made of polyvinyl chloride fiber and ultra-fine metal wire is helpful for X-ray imaging, but it has problems with the original function of gauze as a fiber product that is toxic or has poor hand feeling and softness.
Moreover, clothes, etc., which improve the cooling effect by the heat of vaporization during sweat evaporation, have a certain temperature regulation function and heat insulation, but only have the function of cooling or keeping warm, which will limit their use.
[0012] In addition, even when these various fibers are combined, it is difficult to manufacture fiber products with various characteristics such as antibacterial properties, antistatic properties, anti-heating properties, flexibility, electromagnetic wave shielding properties, and aesthetic appearance of products.

experiment example 1

[0030] (1) Manufacture of laminated wire

[0031] Pure silver was vapor-deposited on a polyester film (manufactured by Toyobo Co., Ltd.) with a thickness of 12 micrometers by ion vapor deposition to form a vapor-deposited film with a thickness of 50 nm. Then, the polyester films having the above-mentioned vapor-deposition coatings were bonded to each other with a polyester-based adhesive so that the vapor-deposition coatings all faced inward, to manufacture a laminated body having a sandwich structure. Finally, the above-mentioned laminated body was cut into a width of 226 micrometers along the longitudinal direction to become a laminated wire, which was used in the following various experiments.

[0032] (2) Antibacterial test

[0033] The antimicrobial property test was carried out by the flask vibration method using a terry base fabric in which laminated yarns were woven at intervals of 6 mm on the base yarn. Streptococcus pneumoniae was used as the test bacteria, and unp...

[0067] (8) Manufacture of twisted yarn

[0068] On a polyester film (manufactured by Toray) with a thickness of 9 microns, a metal coating with a thickness of 50 nm consisting of pure silver (purity 99.99%, manufactured by Mitsubishi Materials Co., Ltd.) was formed by vacuum evaporation technology, and a polyester adhesive ( (manufactured by Sumitomo 3M) were bonded together so that the vapor-deposited coatings were all directed inward, and the formed synthetic resin films were cut into a width of 150 micrometers to produce a laminated yarn. Then, a polyester yarn of 30 denier / five monofilaments and this laminated yarn were reversely twisted into one yarn in the left and right directions to produce a twisted yarn.

[0069] (9) Manufacture gray cloth for suit lining

[0070] On the warped warp of 50 denier / 10 monofilament polyester yarns (manufactured by Toray Co.) at a rate of 150 per inch, weave 30 yarns of 75 denier / 72 yarns at a total of 70 yarns per inch. The monofilamen...

[0074] (11) Manufacture of gray fabric for suit lining

[0075] Fabrics for inner suits were produced in the same manner as in (9), except that the twisted yarns produced in (8) were changed to 10 per inch and at equal intervals, and were dyed black with disperse dyes. The twisted yarn in the gray fabric for this suit has a black metallic color, and the distance between the twisted yarns is about 2.5mm.

[0076] (12) Thermal insulation test

[0077] Use 75 denier / 72 filament polyester yarns (manufactured by Toray Co.) instead of twisted yarns, and use the same method as (11) to manufacture experimental control samples, and then follow the steps (a) to (d) below. Thermal insulation experiment. First, (a) set up the light in the direction of the cloth piece (use two domestic WB type bulbs: PRF-500W); (b) set the The experimental control sample and the gray cloth for the suit manufactured in (11) were respectively combined with two pieces of brown cloth and placed in a screen ...

Abstract

A laminated yarn. The yarn is free from the lowering of antibacterial activity by repeated washing, is excellent in the prevention of rise in its temperature, the insulation of heat and an electromagnetic wave, and antistatic properties, and has excellent appearance. The laminated yarn is characterized in that it is prepared by a method comprising evaporating an antibacterial metal onto a synthetic resin film to form a vapor deposition membrane, adhering the resultant synthetic resin films so as for the vapor deposition membrane to be positioned inside, and cutting the resultant laminated film having a sandwiched structure in a long narrow form along its longitudinal direction.

Description

technical field [0001] The present invention relates to a laminated yarn having a laminated structure, and in particular to a laminated yarn excellent in various properties such as aesthetics, antibacterial properties, washing resistance, heat prevention, heat insulation, antistatic properties, flexibility, and electromagnetic wave blocking properties. Laminated wire. Background technique [0002] In recent years, due to the development of hygienic concepts, products with antibacterial properties have been pursued. Regardless of medical gauze or bandages, even clothes and rags are also required to have antibacterial properties. These antibacterial gauze and the like are made of antibacterial silk as a material. [0003] As such an antibacterial wire, currently used is an ultrafine metal wire drawn by silver or copper, or an electroplated wire in which silver or copper is plated on the surface of a synthetic fiber or the like, or a wire containing an antibacterial agent by i...
