JPS62149780A - Side tape for zipper - Google Patents

Abstract

PURPOSE:To obtain the titled tape which has excellent thermal adhesion characteristics, appearance, washability with water, and durability, and a high commodity value, by laminating a transparent polyester copolymer film having a melting point in a specified range on one side of a transparent nylon film. CONSTITUTION:The titled tape having a thickness of 100-300mu is obtained by laminating a transparent polyester copolymer film having a thickness of 30-180mu and a melting point of 80-200 deg.C on one side of a transparent film of nylon 6 or nylon 6.6, having a thickness of 80-200mu by dry laminating or co-extrusion.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a zipper horizontal adhesive tape, and more particularly to a transparent zipper horizontal adhesive tape with excellent thermal adhesive properties.

(Prior Art and Problems) Conventionally, in the process of producing ZINOPA, horizontal tapes have been used to reinforce the stopper at one end of ZINOPA to the ZINOPA base fabric, and to prevent the ZINOPA base fabric from unraveling. However, since Zinoper is used for a variety of purposes including clothing, there are many materials and color patterns used for the zipper base fabric, so the horizontal tape is also heat-bonded to one side of the fabric of the same color as the zipper base fabric. Therefore, the same number of horizontal tapes as the color and pattern of the zipper base fabric were required, making inventory management complicated and the work complicated.

(Object of the Invention) The present invention is intended to improve the above-mentioned drawbacks and to provide a transparent Zinoper tape with excellent thermal adhesion properties.

(Structure of the Invention) The present invention is a horizontally applied ZINOPAR tape made by laminating a polyester copolymer film having transparency at an axis point of 80 to 200°C on one side of a transparent nylon 6 or nylon 6.6 film. .

Transparent nylon 6 or nylon 6 used in the present invention
6. The film may be any film that is generally used as a transparent nylon film.

The thickness of this nylon film is 80-200μ.

The transparent polyester composite film used in the present invention is a film made by a conventionally known manufacturing method, and the thickness of the film is 30 to 180 μm, preferably 50 to 120 μm.
It is μm.

The transparent polyester copolymer here has a melting point of 80~
200℃, preferably 4'! , is a molecular compound formed by cocondensation polymerization of diol and dicarboxylic acid at 100 to 150°C. Diol components include ethylene glycol, propanediol, butanediol, neopentyl glycol, 2.4-)methyl-2-ethylhexyl-1,3
-'; All, hexanediol, octanediol,
These include deca-diol, cyclohexane dimetatool, p-xylene glycol, and ester-forming derivatives thereof.

Examples of dicarboxylic acids include terephthalic acid, isophthalic acid,
Phthalic acid, adipic acid, sepatic acid, dodecane dicarboxylic acid, dimethyl terephthalic acid, naphthalene dicarboxylic acid, biphenyl dicarboxylic acid, oxalic acid, malonic acid, succinic acid, cultaric acid, himelic acid, bis(phenoxy)
These include ethane Pop'-dicarboxylic acid, azelaic acid, cyclohexanedicarboxylic acid, and ester-forming derivatives thereof. Of course, copolymerization or polymer blending with other monomers can also be used as appropriate, within a range that does not significantly reduce the properties of the polyester copolymer.

A conventionally known lamination method can be used for laminating the nylon film and the polyester copolymer film.

Specifically, dry lamination method and coextrusion method are used.

In this case, it is preferable to use an adhesive for lamination.

Since the ZINOPAR horizontal tape of the present invention is used to fix and reinforce the zipper stopper to the base fabric and to prevent unraveling, the thickness of the tape is appropriate at 100 to 300 μm. and the width of the base fabric.

A horizontal tape slit to a predetermined width is thermally bonded to the zipper base fabric using high frequency waves, ultrasonic waves, or a hot plate, and a stopper is caulked thereon for fixation and reinforcement.

(Effects of the invention) Since the ZINOPAR horizontal tape of the present invention is transparent, it can be easily attached to zippers.
Since the color and pattern of the base fabric is transparent, it can be used regardless of the color and pattern of the base fabric, eliminating the need for complicated inventory management, and having a beautiful appearance and high commercial value. In addition, it is suitable for washing with water and has excellent durability.

(Example) Examples 1 to 5 Nylon 6 with thicknesses of 80μ, 100μ and 200μ
and nylon 66 film and transparent PBT resin as Asahi Kasei (barrel) - Deck C6”
Films with thicknesses of 50μ, 80μ, and 100μ were produced by the usual T-tie method using a 300 (9 points: 125°C).

Nylon 6 film and polyester copolymer film and nylon 66 film and PBT film were dry laminated using polyurethane as an adhesive. Table 1 shows the specific structure and transparency of the prototype film (78
The value of light transmittance at 0 μm is shown.

Table 1 [- The performance of Zinoper as a horizontal adhesive material was evaluated using the prototype composite film.

That is, as zipper plugging, a 15 m wide tape-shaped oil-cut laminated film was hot-melt adhered to one side of polyester (100%) fibers using a hot plate, and the Ngi degree and appearance were tested in normal conditions and after washing with water. did.

The results are shown in Table-2.

Table 2 cE) ml) The adhesive sample was poured into room temperature water containing 0.3% neutral detergent, washed for 30 minutes, and then dried at 60°C for 30 minutes. The adhesive strength after repeating this operation five times is shown.

From the results in Table 2, the laminated film according to the present invention
It can be seen that it shows excellent adhesive strength as a horizontally applied tape, and also has excellent transparency before and after adhesion.
