Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing stretchable fabrics such as knitted fabrics coated with metal.

Conventionally, as a method for manufacturing a fabric on which a metal vapor deposition transfer of aluminum or the like is applied, for example, Japanese Patent Application No. 187441/1987 filed by the present applicant = (Japanese Unexamined Patent Publication No. 58-1989)
There is an invention disclosed in No. 1891). The method of this invention involves laminating a fabric by a dry lamination method or the like on the vapor deposition surface of a metal vapor deposition base material from which the metal vapor deposition layer can be peeled off, and then peeling off the metal vapor deposition base material and the fabric and winding them up separately. According to the above, the gist is to form a vapor-containing layer on the surface of the fabric, but the fabric used must at least not be stretchable, and should not be a stretchable knitted fabric, for example, When using a tricot knitted fabric, it was not possible to transfer the metal deposited layer uniformly and neatly due to its stretchability.

The present invention was invented in view of the above-mentioned points, and provides a beautiful and appropriate breathability for fabrics such as stretchable knitted fabrics, which were conventionally thought to be unable to transfer beautiful metal vapor deposition. It is an object of the present invention to provide a method for manufacturing a stretchable fabric with metal vapor deposition transfer that can also exhibit the following properties.

The configuration of the present invention will be explained below.

In other words, the gist of the present invention is that in the step of adhering a stretchable fabric via an adhesive to the vapor deposition surface of a metal vapor deposition base material onto which a metal vapor deposition layer can be transferred, the fabric is opened. After bringing the member into a state where there is no shrinkage, the two are bonded together, and when the adhesive is in a semi-hardened state, the metal vapor deposited base material and the fabric are peeled off to transfer the metal vapor deposited layer to the fabric side, and then,
The metal vapor deposition transfer method is characterized in that the fabric to which the metal vapor deposition layer has been transferred is passed between a pair of pressure rolls, the metal vapor deposition layer is pressed between the loops of the fabric, and the adhesive is completely cured. This is a method for producing a stretchable fabric.

Next, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a preliminary process diagram for carrying out the manufacturing method of the present invention;
FIG. 2 is also a subsequent process diagram.

In the drawings, reference numeral 1 indicates a stretchable fabric, for example,
A knitted fabric such as tricot knitting is fed out from an unwinding roll 2 at a constant feeding speed. This fabric 1 is held in a state in which the fabric itself does not shrink by running over openable members such as a screw expander roll 7 and a flat expander roll 8 via guide rolls 3, 4, 5 and 6. This and the metal vapor deposited base material 9 on which dry lamination has been applied to the moon surface, which is fed out from the other side, are bonded together with a pressure roll 10 at a predetermined pressure, and then wound up with a first winding roll 11. This rolled up laminated material 1
2, after aging for a predetermined time, the feeding roll 1
When the fabric 1 and the metal vapor-deposited base material 9 are peeled off again from step 3, the metal vapor-deposited layer is transferred to the fabric side, and the fabric with the metal vapor-deposited layer transferred is shrunk by the flat expander roll 15. After being crimped with a predetermined pressure by the press roll 16 without any flat expander 1
7, the material is wound onto the take-up roll 18 side without shrinkage, and then the metal vapor-deposited base material 9' (However, the metal vapor-deposited layer of the metal vapor-deposited base material 9 has been transferred to the fabric side. (therefore, it is essentially only a carrier film) is wound up with another winding roll 14.

Here, the term "fabric" refers to, for example, a stretchable knitted fabric such as Tricono 1-knitted fabric, but it is not limited to this type of fabric, and needless to say, any fabric can be used.

The screw expander roll used in the present invention is one in which a protrusion 19 is provided on the peripheral wall in a spiral or link shape outward in the width direction, as shown in FIG. As shown, a straight protruding strip 19' is provided in the width direction.

In addition, the linear pressure on the pressure roll is 5 to 40 kg/cm.

Preferably, it is as high as about 30 to 40 kg/cm.

Furthermore, the hardness of the rubber of this pressure roll is, for example, 75.
Something about ° is good.

Furthermore, after bonding the metal vapor deposited base material and the stretchable fabric, this is preferably aged for about 224 hours at 40° C. until peeled off.

By the way, the metal vapor deposited base material to which the metal vapor deposited layer used in the present invention can be transferred is, for example, as shown in FIG. 22, or as shown in FIG. 6, a top coat layer 23 is applied to a synthetic resin film 20 via a release agent layer 21, and a metal vapor deposition layer 22 is provided thereon. As shown in the figure, there is a synthetic resin film 24 with good releasability and a metal vapor deposited layer 22, but it is not limited to these. Any material may be used as long as the metal vapor deposited layer can be transferred onto the fabric surface.

Here, as the synthetic resin film used for the metal vapor deposition base material, for example, films of polyester, polyethylene, polystyrene, biaxially oriented polypropylene, acrylic, etc. are suitable, and as mold release agents, cellulose acetate, nitrified cotton, acrylic wax, etc. As the metal to be vacuum-deposited, metals such as aluminum are suitable, and synthetic resin films with good mold release properties include biaxially oriented polypropylene blended with an appropriate amount of silicone resin.

Note that the ear opening member means a screw expander roll, a flat expander 1-J-roll, a tenter, a cross guider, etc., and it prevents the elastic fabric from shrinking and widens the width of the fabric (both ear portions). ) and are used to provide a wrinkle-free condition, and these are used alone or preferably in combination as shown in the above examples.

Therefore, the stretchable fabric with the metal vapor deposited layer produced through the above-mentioned procedure has a beautiful metal vapor deposit layer transferred thereon, and the metal vapor deposit layer digs into the fabric's edges and causes slight damage. Visually, the metal layer has holes in many places, so
It also has moderate breathability, and because of this breathability and the heat insulation properties of the metal vapor deposited layer and fabric, it is generally used in a wide range of applications that require heat retention and moderate breathability, such as clothing-related materials. There is.

The present invention configured as described above has the following effects.

txt First, according to the present invention, it is possible to beautifully transfer a metal vapor deposited layer onto stretchable fabric, which was conventionally considered to be extremely difficult to transfer.

(2) Furthermore, in the fabric to which the metal vapor deposited layer produced according to the present invention has been transferred, the metal vapor deposit layer digs into between the loops constituting the fabric, and microscopically, the metal vapor deposit layer has holes in various places. Therefore, it has appropriate breathability, and this breathability and heat retention (insulation), which is the original property of the fabric and the metal deposited layer, are optimal properties as a material for clothing.
Can be widely used for clothing.

(3) Furthermore, in the present invention, an open member such as a screw expander roll and a furan 1 to expander roll is prepared before bonding the metal vapor-deposited base material and the fabric, and the metal vapor-deposited layer is transferred. Since this can be carried out by simply preparing an opening member such as a flat expander roll before winding up the fabric, it is extremely rational as conventional equipment can be used as is.
