2. Description of the Related Art Feathers (including natural and man-made) filled between front cloth and back cloth, futons filled with cotton (including natural and man-made), bedding such as sleepwear, down jackets, windbreakers , Ski wear, stadium jumper, stadium parka, etc. have the advantage that the winter clothes used indoors and outdoors in the low outdoor temperature season have excellent heat retention, lightweight, comfortable to wear, easy to handle, etc.
It is extremely widespread. The drawback of these products is that the filled feathers, cotton, etc. move between the front and back fabrics during use,
In extreme cases, feathers, cotton, etc. may swell toward one side of the front and back fabrics, and the rest may be only the front and back fabrics.

In order to improve such drawbacks, a method of sewing (sewn) front and back fabrics at regular intervals, a method of sewing so that the sewn portions appear in a straight or curved pattern on the front and back fabrics, and feathers For a futon, a method has been proposed in which partition cloths are attached to the front and back cloths in a grid pattern to form a large number of small compartments therein (JP-A-5-4029).

Although there is no problem when the partition cloths are attached to the front and back cloths in a grid pattern, it has been attempted to make the attachment lines appear in a curved pattern for the purpose of improving the design of the product. In the latter case, a method of temporarily attaching (temporarily placing) the partition wall cloths to the front and back cloths and then joining the partition cloths to the front and back cloths is adopted. When joining after temporary placement, there is a drawback that a beautiful curved pattern cannot be formed because the end portions of the partition cloth move only by temporarily placing the end portions of the partition cloth on the front and back fabrics.

In order to solve the above-mentioned drawbacks, a method of interposing a double-sided adhesive tape for joining the front and back fabrics on the ends of the partition fabric, a tape is joined to the ends of the partition fabric, and the tape is contacted with the front and back fabrics. A method of applying an adhesive to the surface and adhering it has been proposed. However, when temporarily placing (temporarily fixing) using a tape coated with an adhesive and sewing this tape on the front and back fabric, the adhesive needle adheres to the sewing machine needle for sewing and There is a drawback that breakage may occur and the broken sewing needle remains in the product, and the removal work of this is complicated.

[0006] In order to avoid such residual breakage of the sewing machine needle, there is also a method in which the sewing machine is not sewn and the product is made by joining only with an adhesive. However, depending on the type of adhesive, the adhesive bleeds on the surface of the front and back fabric,
There are drawbacks such as discoloring the front and back fabric. Also, if a product that has been contaminated by use is subjected to dry cleaning, the adhesive will dissolve in the cleaning solvent, or the adhesive will not dissolve in the cleaning solvent but the adhesive strength will be weakened by subsequent washing, and the partition cloth will There was a drawback that it could no longer function as a partition.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks when temporarily fixing (temporarily placing) the ends of the partition cloth, and the ends of the partition cloth are placed on the front and back sides. When temporarily placed on the cloth, the partition cloth will not move, it will not adversely affect the subsequent sewing work, the filling work of feathers, cotton, etc., and the product quality will deteriorate during use. It is an object of the present invention to provide an improved adhesive tape which is suitable for temporarily placing the ends of the partition cloth.

[0008]

In order to solve the above problems, according to the present invention, two kinds of adhesives having different adhesive performances are provided on one surface of a long fabric base material along the length direction. The present invention provides an adhesive tape characterized by being applied.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.
The adhesive tape according to the present invention uses a long cloth as a base material.
One side of this base material is joined to the ends of the partition cloth, and the other side is coated with two kinds of adhesives having different adhesive strengths. The ends of the partition cloth are temporarily fixed on the front and back fabrics ( It functions so as not to move the end of the partition cloth when it is temporarily placed).

The fabric of the base material may be woven fabric, non-woven fabric or the like, and the material of the fabric is not particularly limited, and may be synthetic fiber, natural fiber or the like. In the case of a woven fabric, the fibers are preferably as thin as possible, and the non-woven fabric is also preferably as thin as the strength allows. In addition, the fabric of the base material needs to be long. This depends on the type, size, and structure of the product, but the part where the edge of the bulkhead fabric is temporarily placed on the front and back fabrics can usually reach several meters to a dozen meters. It is long to accommodate. If the width of the adhesive tape is too wide, it is not economical, and if it is too narrow, the function of temporary fixing (temporary placement) cannot be exhibited. Usually, the width of the base fabric that becomes the tape depends on the type of the fabric and the use of the tape, but is 5 mm to 20 mm.
Selected in the mm range.

In the adhesive tape according to the present invention, it is necessary that two kinds of adhesives having different adhesive performances are applied along the length direction on the surface which is not joined to the end of the partition cloth. One adhesive (a) has the function of adhering to the fabric on the front and back when it is temporarily fixed (temporary placement), and the other adhesive (b) uses the edge of the partition fabric as the fabric on the front and back. Exerts the function of adhering to. Examples of the combination of the adhesive (a) and the adhesive (b) include a combination of a tacky adhesive and a hot-melt adhesive, a combination of hot-melt adhesives having mutually different adhesion temperature ranges, and the like.

The tacky adhesive is an adhesive that exhibits tackiness at room temperature, and can be temporarily fixed (temporarily placed) to the end of the partition cloth and the cloth on the front and back without using a heating tool. Examples of the tacky adhesive include rubber adhesives, acrylic resin adhesives, polyvinyl acetate adhesives, polyvinyl alcohol adhesives, ethylene-vinyl acetate adhesives, and polyamide adhesives. Among them, polyisoprene adhesive, SBR adhesive, SIS (styrene-isoprene-styrene block copolymer) adhesive, SBS
Rubber-based adhesives such as (styrene-butadiene-styrene block copolymer) adhesives and SEBS (styrene-ethylene-butadiene-styrene block copolymer) adhesives are suitable.

The hot melt adhesive is an adhesive which exhibits a tackiness when it is liquid or melted by heating. As the hot melt adhesive, ethylene-vinyl acetate copolymer, polyamide, polyester, atactic polypropylene, etc. are the main components, and rosin-based resins, petroleum resins, etc. as waxes, waxes, and antioxidants , Various additives such as inorganic fillers and plasticizers are blended. At that time, the adherable temperature can be adjusted by changing the compounding ratio depending on the application of the hot melt adhesive.

The above-mentioned adhesive must be applied along the length direction of the fabric of the base material. “Along the length direction” means that two kinds of adhesives having different properties are applied along the length direction of the fabric. The form of this application is as follows: (1) Adhesive (a) and adhesive (b) are applied half width each, (2) Adhesive (a) or adhesive (b) (b) or adhesive (a) is applied in two lines, a total of three lines, (3) adhesive (a) or adhesive
(b) is applied in multiple lines, (4) Adhesive (a) is applied over the entire surface, and adhesive (b) is applied in dots at regular intervals, (5) A form in which both the adhesive (a) and the adhesive (b) are alternately applied at regular intervals, and the like are mentioned, but the forms are not limited to these exemplified forms. From the viewpoint of producing an adhesive tape, the preferable application form is the form (1) or (2).

The method for producing the adhesive tape according to the present invention is not particularly limited as long as it satisfies the above structural requirements. As an example of the production method, (i) a method of preparing a long fabric base material and applying two kinds of adhesives having different properties along the length direction thereof, (ii) a long and wide fabric base material Is prepared and a plurality of strips of two kinds of adhesives having different properties are applied along the length thereof,
There is a method of cutting this into a certain width so as to satisfy the above structural requirements. When the adhesive tape is coated with a tacky adhesive, it is preferable that a thin film made of plastic such as polyethylene is laminated as a liner on this surface, and the laminated film is peeled off before use.

When the adhesive tape according to the present invention is actually used, the end portion of the partition cloth is placed on the surface of the adhesive tape on which the adhesive is not applied, at the approximate center of the length direction along the length direction. The seams are sewn with one or two stitches, and the surface coated with the adhesive is temporarily fixed (temporarily placed) on one of the front and back fabrics, and the adhesive tape is joined to the front and back fabrics in earnest. For full-scale joining, (1) a method of adhering the hot melt adhesive application surface to the front and back cloth by thermocompression bonding, (2) a method of sewing the front and back cloth and the adhesive tape with a sewing machine, (3)
Any of the above methods (1) and (2) may be combined. When the adhesive tape is sewn on the front and back cloths with a sewing machine as in the methods of (2) and (3) above, even if the adhesive dissolves or is washed away by the cleaning solvent or water, It doesn't stop working.
