Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a heat-reflecting cloth for keeping warm or cold.

Up until now, this type of reflective cloth has been on the market, and there are various manufacturing methods such as pasting aluminum foil on the base cloth, pasting alkali-deposited film Y on the base cloth, and coating with aluminum powder. It had been taken. However, the soft method of pasting aluminum foil or distilled film results in a flexibility that is very different from the original base fabric, and the method of coating aluminum powder results in a random arrangement of aluminum, resulting in a gray appearance. It had become.

The present invention has been devised in consideration of the above points, and will be described in detail below with reference to the drawings.

First, Figure 1 shows the transfer foil, and the support film layer (31K
Aluminum vapor 51711 (11 is provided) through the mold release agent layer (2).

The support film layer (3) is made of OPP, PET, PR
.

CPP film Y is used. This is because these materials have surface smoothness, are relatively inexpensive, and are easy to select as a mold release agent, which will be described later.

For the mold release agent layer (2), nitrocellulose, chlorinated rubber, acrylic, polyester, or polyether is used as the main ingredient, and an acidic agent is added as necessary.

Also, silicon or wax-based resin is added as a mold release additive to adjust the adhesive strength with the support film. The amount of mold release agent applied is 1g/- to 10f, but
A large number of layers are sometimes used to protect the aluminum evaporation, which will be described later. As a coating method, Hakura Biakko F, reverse coating, roll coating, air knife coating, etc. can be used.

The aluminum vapor deposition layer (1) is provided by vacuum vapor deposition of aluminum, and the thickness is 400A to 1000A. j is appropriate. In other words, it is sufficient that the alkali layer forms a complete layer and a mirror surface appears.

Next, the thus formed transfer foil is pasted together via the base fabric layer (nonwoven fabric or cloth) (5) and the K adhesive f11 layer (4). (Figure 2) The adhesive for the cough adhesive layer (4) should preferably have high fluidity.

If the amount of adhesive to be applied is small, it is preferable to apply it to the Al-Z vapor deposited side. This is because if the adhesive is applied to the base fabric layer, it will penetrate into the base layer and lose its adhesive function.

However, if the amount of adhesive is large and the fluidity of the adhesive is low, there is no problem in placing it on the base fabric side. Specifically, as the adhesive, polyester-based, acrylic-based, ether-based urethane adhesives, =rm-based S17 adhesives, vinyl acetate, EVA $0 emulsion adhesives, etc. can be used.

After bonding the transfer foil and the base fabric, the support film (3) is peeled off when the contact strength of the adhesive becomes greater than the adhesive strength of the release agent to the support film. This becomes K when a very glossy aluminium-based vapor deposited film having the smooth surface of the support film is transferred to the base material, which has the uneven surface of the base fabric. In addition, since the mold release agent layer (2) is also transferred at the same time, the aluminum layer is protected and the aluminum is not easily oxidized.Furthermore, according to the present invention, the vapor deposited film layer is extremely thin and the aluminum layer is protected. The elasticity of the very soft cloth itself, which is produced by the waist as a foil, is what we get.

The circumferential speed of the product according to the present invention can be widely used in the fields of heat and cold insulation, such as outer scissors for drinking water coolers, 7-ton core materials, heating layers for clothing, emergency evacuation sheets for ground detection, fire-resistant clothing, etc. It can be used for

〔Example〕

OFF film 20μ thick additive-free product was coated with Toyo Ink's acrylic polyurethane resin [2b, gravure] as a release agent, and then 7Ki' was applied on top of it.
A transfer foil was prepared by vacuum deposition to a thickness of 500 J.

Next, apply polyether adhesive BH8 $6020A CY 5 f/ manufactured by Toyo Morton Co., Ltd. to the aluminum surface of this transfer foil.
Wl was applied, and then Asahi Kasei's nonwoven fabric N5020'l' was applied.
The lamination was left at room temperature for 1 time, and then the OFF film was peeled off to obtain a non-woven fabric having an alkali metallized surface.

Next, place the diameter 0, 31 at each corner point of this KIO mackerel square.
Eleven holes were drilled and an Al electric picture was placed on the right circular side of the lining of a kotatsu futon so that it was in contact with the lining, and the temperature rise was compared between those using the product according to the present invention and those without.

As a result of the rise in temperature of the kotatsu, it was found that the futon using aluminium-deposited non-woven fabric had a good effect on extreme pressure. Also, there was no noise like when moving the futon for 9K and attaching Al 1 foil.

As described above, according to the present invention, compared to the conventional manufacturing method, it is possible to obtain a paper sheet with a very smooth and glossy surface due to the transfer method, and the present invention is extremely useful in practice.
