Description

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a core material used when a cut edge such as a pocket opening of clothes is treated with a bead.
[Prior art]
The edge of the cloth, such as the hem, cuffs or pockets of the clothes, is usually wrapped with a separate cloth to prevent the cloth from fraying, and the edging process is adopted. Is called. In particular, in places where emphasis is placed on decorativeness, such as a pocket mouth, a method of putting a yarn of a predetermined thickness as a core material in a bead to finish it in a plump shape has been conventionally employed. .
[Problems to be solved by the invention]
When wool is used as the core material of the bead as described above, it is extremely difficult and extremely inefficient to pass the wool through the bead that has been subjected to the framing treatment of the cloth.
As a means to solve this, a wool is placed on a base cloth such as a thin non-woven fabric and sewn with a sewing machine to form a core material for a ball, and the core material is bonded to the back of the cloth for the ball. In addition, it is conceivable to perform a conventional bead processing by wrapping the yarn with a bead cloth. In this way, it is possible to eliminate the difficult and inefficient work of passing the yarn through the bead, and to improve the efficiency of the bead processing work.
However, the above-described measures of sewing a yarn on a base cloth to form a core material for a ball have the following problems.
In other words, when wool is placed on the base cloth and sewn with a sewing machine, wrinkles are generated in the base cloth due to shrinkage of the sewing, and the work for sticking to the cloth for the bead and the processing for the bead to wrap the wool. Is difficult to perform smoothly.
In addition, for example, in a case where the ball edge is formed by abutting both sides of an opposite cut edge such as a pocket mouth (generally referred to as both ball edge), as shown in FIG. Further, two yarns b, b are arranged in parallel at a predetermined interval d, and these are sewn c with a sewing machine to form a core material for a bead. Then, the core material is adhered to the back of the bead fabric e to form a bead member. The beaded cloth e is bonded (or adhered) to the surface of the cloth to be formed into a pocket, and the central side edges of the yarns b, b are sewn to the cloth. A cutout g is formed in the center of the distance d between the two yarns b, b to form a pocket opening, and a gap between the ball cloth e and the base cloth a is formed. The yarns b, b on both sides are wrapped in a half of d, respectively, and the side edges h, h of the yarns b, b are sewn to the folded portion of the pocket opening, and are pushed into the pocket opening. It constitutes a so-called bead pocket having two joined beaded beads. In this case, the way in which the wool b is wrapped differs depending on the size and type of the pocket, the manner of sewing to the pocket mouth, and the like, and the required distance d of the two wools b, b also differs accordingly.
However, in the above-described method of sewing the two yarns b and b on the base cloth a with the sewing machine c, the distance d between the yarns b and b is determined by the standard width of the sewing machine. The degree of freedom must be limited, and there is a problem that a machine other than the standard width of the sewing machine, for example, a machine having an interval d smaller than the standard width cannot be machined.
An object of the present invention is to solve the above problems.
[Means for Solving the Problems]
The present invention provides, for example, a method of arranging wool on a base cloth made of a thin cloth such as a nonwoven fabric, and bonding a covering cloth made of a thin cloth such as a nonwoven cloth to the base cloth and the wool, thereby forming a wool base cloth. The first feature is that a core material for a bead is formed by being sandwiched and fixed between the cover and a covering cloth.
As a result, there is no fear of sewing shrinkage or wrinkles, etc., as compared with the case where the wool is sewn on the base cloth with a sewing machine to form a core material for a bead. By changing and combining the materials of the upper and lower fabrics in various ways, it is possible to expand the degree of freedom such as the variation of the stretching prevention effect and the texture.
The present invention also provides, for example, two yarns arranged in parallel at a predetermined interval on a base cloth made of a thin cloth such as a non-woven cloth, and the covering cloth made of a thin cloth such as a non-woven cloth is used as the base cloth and the two cloths. The second feature is that the two yarns are sandwiched and fixed between the base cloth and the covering cloth to form a core material for both the rims.
Thereby, in addition to the same operation and effect as in the case of the first feature, the interval between the two yarns can be freely set in a wide range from the minimum to the maximum, and the production efficiency can be improved by machine production. In addition, the effect (effect) that the standard (thickness) of the yarn can be easily dealt with only by changing the nozzle of the attachment can be obtained.
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing an example of a core material for a bead according to the present invention. Reference numeral 1 denotes a base cloth made of a thin cloth such as an extremely thin nonwoven cloth, and an elongated strip having a predetermined width (for example, about 60 mm). Make a shape. On the base cloth 1, two yarns 3 and 3 having a predetermined thickness are arranged in parallel in the longitudinal direction at an interval d, and a covering cloth 2 made of a thin cloth such as an extremely thin nonwoven cloth is placed thereon. The wools 3 are bonded and fixed while being sandwiched between the base cloth 1 and the covering cloth 2. Thus, the core material 4 for the bead is configured.
An adhesive layer is formed on the back surface (the surface opposite to the surface on which the wool is provided) of the base fabric 1 by an adhesive resin processing or the like as necessary, and can be easily pressed or heated and pressed against the cloth for the bead. It can be glued.
The core material 4 for a bead configured as described above is cut at a predetermined length in the longitudinal direction, and as shown in FIG. Thus, the bead member 6 is formed.
A method of forming a bead pocket using the bead member 6 will be briefly described below with reference to FIGS.
First, the back surface (the surface opposite to the surface to which the core material 4 is bonded) of the bead material 6 of the bead member 6 is joined (or adhered) to the surface of the garment 10 where a pocket is to be formed, and the yarn 3, 3 is sewn to the fabric 10 at the center side edge. Next, a cut 8 is made in the bead member 6 and the garment 10 at substantially the center of the interval d between the yarns 3 and 3, and the portion of the garment 10 between the sewing portions 7 and 7 and the cut 8 is turned to the back. The pocket opening 11 having the folded portions 11a is formed by folding. Then, the yarn 3 on the left side is wrapped in the portion on the left side of the cut 8 and the yarn 3 on the right side in the portion on the right side of the cut 8 in the gap d portion of the bead member 6 divided into two by the cut 8, and The part of the member 6 on the side of the two yarns 3, 3 is wrapped around from the pocket opening 11 to the back side, and is sewn on the folded parts 11a, 11a. Thus, a so-called bead pocket in which the pocket opening 11 is terminally processed can be obtained.
A method of forming a ball pocket by the ball member 6 is the same as a conventionally known method. FIG. 3 shows a method of forming a ball pocket called a split, and FIG. It is an edge pocket construction method.
FIG. 5 shows an example of a method of forming a fringe pocket of a pocket with a flap. Reference numeral 12 denotes a flap including a flap outer material 13 and a flap lining 14, and 15 denotes a pocket. The method of forming the pocket of the flap pocket is also well-known in the art, similarly to the method of forming the pocket of the pocket called "split" and the method of forming the pocket of the pocket called "flipped" shown in FIGS. Therefore, detailed description is omitted.
The core material 4 for a bead according to the present invention is constituted by sandwiching and fixing one wool 3 between a base cloth 1 and a covering cloth 2 as shown in the embodiment of FIG. 6, for example. Although it can also be applied as a core material for one bead, particularly when applied to a core material for both beads as in the embodiment of FIGS. It can be freely set in a wide range from about 4 mm to about 30 mm or about 40 mm, and can appropriately respond to any demand in the industry.
