JPH0748700Y2 - Gold and silver flat foil yarn for narrow fabrics used for warp - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention has an excellent longitudinal strength, which is optimum as a warped warp for narrow width fabrics, ribbons, woven names or narrow width fabrics such as tatami edges. The present invention relates to a tough gold-silver flat foil yarn.

2. Description of the Related Art Conventionally, a decorative plain yarn for revealing a pattern has been used in order to bring out a subtle dark and light paint color to a woven fabric, and this decorative plain yarn may be used as a weft yarn or a warp yarn.

For example, Japanese Examined Patent Publication No. 60-7751 discloses a pattern revealing warp that is used when weaving a plain yarn obtained by slitting a patterned foil piece as a warp and reproducing the foil pattern on the resulting fabric. A flat yarn has been proposed, and it is possible to simply and accurately apply a pattern with the same and excellent texture on both front and back sides of the foil to the high-class Nishijin woven belt, etc. Techniques for preventing disturbance of reproduced patterns are disclosed.

Further, in JP-A-49-36945, a transparent polyethylene terephthalate film having a multicolor metallic pattern on one side is slit to obtain a flat foil yarn having the same front and back color tones, which is used as a warp. A technique for reproducing the pattern on the woven surface by weaving it is disclosed.

Generally, as a gold-silver flat foil thread applied to a high-class Nishijin woven belt or the like, a metal vapor-deposited film adhered to both sides of a base film to give a unique color tone, texture and the like is known as described above.

These slit gold-silver flat foil yarns give tensile strength in the longitudinal direction in a state where each flat foil yarn is widely gathered when applied as a fabric having a relatively wide width such as a strip. The flat foil yarn has few chances of breakage, but the problem of twisting was still unsolved.

The present inventor has focused on the use of such a conventional gold-silver flat foil yarn for ribbons, woven names, especially tatami edging, which is a narrow woven fabric. When weaving the tatami mat, the technique inevitably pulls strongly in the longitudinal direction due to the narrow width, resulting in poor tensile strength and curl and other twisting, resulting in poor practical value. It was also found that it was inferior in wear resistance and durability due to the tatami edge.

The problems to be solved by the invention Therefore, the gold-silver flat foil yarn for narrow width fabrics to be used for the warp according to the present invention eliminates the conventional defects described above, and in particular, imparts tensile strength in the longitudinal direction toughness. Narrow fabrics, eg 8-10
Even when woven into a tatami mat with a desired width of cm, it does not break practically, has the same toughness as a tatami mat with a plain weave structure made of conventional nylon thread, and has a strong mechanical strength, so that it does not twist. An object of the present invention is to provide a gold-silver flat foil yarn for a narrow woven fabric, which is to be used as a warp that does not have an edge.

Furthermore, since it is maintained in a warp-shaped twisting pattern, the pattern of the laminated sheet can be faithfully reproduced, and if the structure of the double warp is applied, a different pattern design can be applied to the pattern of gold and silver flat foil. With the aim of providing a gold-silver flat foil yarn for narrow fabrics, which is to be used as a warp capable of producing a pattern portion, it is particularly stable because it has a structure using two uniaxially stretched films. It is an object of the present invention to provide a gold-silver flat foil yarn for narrow width woven fabric, which has excellent warp strength and is used as a warp that has no distortion or twist.

Means for Solving the Problems In order to achieve the above-mentioned object, in the gold-silver flat foil yarn for a narrow fabric used for the warp according to the present invention, one surface of the biaxially stretched polyester film 1 is made of aluminum or other material. A metal vapor deposition layer 2 is formed, and a pattern layer 3 is further formed on the surface of the metal vapor deposition layer 2.
A uniaxially stretched film 4 which does not extend in the longitudinal direction through an adhesive 5 and two sheets A on which a coating layer 6 is sequentially formed, and the biaxially stretched polyester film 1 side is stuck to the inside by an adhesive 7. The laminated sheet B is characterized by a gold-silver flat foil yarn for narrow width fabric, which is used as a warp that is cut into a yarn and wound into a warp for warping.

Next, an example of an embodiment of the gold-silver flat foil yarn for a narrow width fabric used as the warp according to the present invention will be described in detail.

Biaxially stretched polyester film with a thickness of 0.006 to 0.025mm 1
Metal deposition layer 2 with vacuum deposition of aluminum on one surface
To form.

Then, a colored pattern layer 3 is formed on the surface of the metal vapor deposition layer 2 by using, for example, a multicolor gravure printing machine.

The pattern layer 3 is a shade pattern, a perforated pattern, a sand pattern,
Small patterns and other appropriate patterns are applied.

In this way, the surface of the metal vapor deposition layer 2 on which the pattern layer 3 or the like is applied by, for example, a transfer method is further uniaxially stretched film which does not extend in the longitudinal direction via the urethane-, polyester-, or isocyanate-based adhesive 5 in sequence. 4 and the coating layer 6 are formed.

The so-called uniaxially stretched film 4 has a transparent thickness of 0.025 to 0.1 mm.
Of polypropylene film, polyethylene film, polyester film, etc., and at the same time, they are bonded in a direction having strength in the longitudinal direction when cut in the cutting step.

As the coating layer 6, a resin top coating, a matte coating, or the like is arbitrarily applied.

The sheet A obtained based on such a structure is adhered by using two sheets of the sheet A with the biaxially stretched polyester film 1 side as the inner surface and an adhesive 7 of urethane type, polyester type, isocyanate type or the like. To be done. Thus, the laminated sheet B thus obtained is cut into a cut width of 1.5 to 0.2 mm using a micro slitter and the like, and at the same time, the gold-silver flat foil yarn is not entangled. It is wound on a Tikiri roll of sutra-shaped while sandwiching.

Effect of the Invention According to the gold-silver flat foil yarn of the present invention, the warp to be used as the warp has two biaxially oriented polyester films 1 on the inner surface,
Since two uniaxially stretched films 4 are equally formed on the outer surface, and by arranging so as to provide strength in the longitudinal direction after cutting, the gold and silver flat foil yarn after cutting into a yarn is As a narrow width fabric with a small number of flat foil yarns to be used as warp yarns, especially when it is used for tatami edging, where extension is reliably prevented and sufficient tensile strength is given in the longitudinal direction. It becomes substantially stable and has durability that does not break.

Further, since the two uniaxially stretched films 4 are adhered to both outer surfaces of the two biaxially stretched polyester films 1, uniform tensile stress is applied to both sides of the biaxially stretched polyester film 1 and the current after cutting is applied. The warp of the gold-silver flat foil yarn that is easy to be taken out is stabilized without any twist, which leads to excellent adaptability and workability during weaving.

Further, the metal vapor deposition layer 2 can be provided with a suitable pattern pattern by transfer or the like and further protects the surface thereof, so that contaminants can be easily removed and the metal vapor deposition layer 2 is always free from dirt.
And the pattern layer 3 can be exposed.

Since the gold-silver flat foil yarn is a warp yarn having a rectangular cross section, it has the convenience of giving a completely new texture when applied to a tatami mat which has not been used conventionally.

Furthermore, since the gold and silver flat foil yarns are so-called uniform narrow width aggregate yarns that are designed as warps as they are, it is possible to make a certain pattern appear at a certain portion. Since a different pattern design can be formed on the pattern and the same sheet A is used on both sides of the central adhesive 7, there is an effect that there is no fear of distortion, twisting or cutting.
