Abstract

PROBLEM TO BE SOLVED: To provide a fused sewn garment allowing to obtain sufficient joining force, and having durability even if forming the fused sewn garment by a water repellent material hard to join with an adhesive.SOLUTION: This fused sewn garment is obtained by laying an adhesive between joining parts of members forming the garment so as to join the members by fastening the adhesive. In more details, the garment is obtained by fusing by setting through-holes made by cut processing the member, in the joining part of one member to be joined, and pouring an adhesive into the through-holes.

Description

  The present invention relates to a welded garment in which members are joined by welding an adhesive.

  Conventionally, for example, as a method for attaching a fastener to an attachment base material, a method has been proposed in which a hot melt resin is brought into contact and pressure-bonded in a heated state so that the fastener and the attachment base material are integrally bonded (for example, a patent document). 1). However, in the proposed method, it is difficult to obtain the adhesive strength of the hot melt resin to a material having water repellency and the durability of the bonded portion is problematic.

  On the other hand, in order to improve the durability of the bonded part in the joining of the members by welding of the thermal adhesive tape, an enlarged gap is formed on the garment constituting fabric by a sewing machine, and the thermal adhesive tape is permeated into the enlarged gap and joined. There has been proposed a method of welding a part and a thermal adhesive tape (for example, see Patent Document 2). However, as described in the proposal, in the method in which the adhesive tape is infiltrated into the enlarged gap portion expanded by expanding the stitch or weave by inserting the sewing needle, the size of the enlarged gap portion is not sufficient, In addition, the enlarged gap portion that was gradually expanded with the passage of time was easy to close, and the adhesive material was not easily penetrated into the enlarged gap portion. In addition, since the enlarged gap portion in which the fibers constituting the stitches or weaves described in the proposal are spread is formed by the smooth side surfaces of the fibers, the adhesive is not affected even if the adhesive penetrates. It was difficult to get entangled with the fiber and sufficient adhesive strength was not obtained.

  Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a welded garment having a sufficient bonding force even for water-repellent materials that are difficult to weld hot melt materials. It is in.

The present invention adopts the following configuration in order to solve the above problems. That is,
It is a welded sewing garment in which an adhesive is interposed in a joint portion between members constituting a garment and the members are joined by welding the adhesive, and by cutting the member into the joint portion of one member to be joined A welded sewing garment characterized in that the obtained through-hole is provided, and an adhesive flows into the through-hole and is welded.

  In the adhesive sewing garment of the present invention, the hole diameter and shape of the through-hole are preferably a hole diameter and shape that can inscribe a circle having a diameter of 2 mm.

  Further, in the bonded sewing garment of the present invention, the joint portion having the through hole is joined from both surfaces via the joint portion of the member to be joined and the adhesive, and is brought into contact with both surfaces of the joint portion having the through hole. It is preferable that the adhesives are fixed to each other in the through hole.

  According to the present invention, a sufficient bonding force can be obtained even for a water-repellent material that is difficult to bond with an adhesive.

It is a figure which shows typically the one aspect | mode of the welding joining part in the clothes of this invention. It is a figure which shows the example of the hole diameter and shape of a through-hole obtained by cutting | disconnection. Here, a circle indicated by a dotted line indicates a circle having a diameter of 2 mm. It is a figure which shows typically the one aspect | mode of the welding joining part in the clothes of this invention. It is a figure which shows typically the one aspect | mode of the welding joining part in the clothes of this invention. It is a figure which shows typically the one aspect | mode of the through-hole in the clothes of this invention.

  The garment of the present invention is a welded and sewn garment in which members are joined by interposing an adhesive material between the joint portions of the members constituting the garment and welding the adhesive material, and the joint portion of one member to be joined It is important that a through-hole obtained by cutting a member is provided in an adhesive, and an adhesive material flows into the through-hole and is welded. In particular, it is important that a through-hole obtained by cutting is provided in a joint portion of one member to be joined. By doing so, the adhesive material soaks into the fibers and members from which the through-holes have been cut, entangles them, and is welded locally to obtain a strong bond. As a result, even when the welding to the surface of the water-repellent material is insufficient, the entire bonding force can be improved by bonding the through-hole portions. The adhesive may be a liquid, gel, paste, or other common adhesive that dries the solvent to fix the adhesive component. A method in which the material is pre-heated and then applied to the joining portion of the member and then cooled and welded, or a method in which the hot melt material is thermally melted in contact with the joining portion of the member and the members are welded together is suitable. It is.

  FIG. 1 shows an embodiment of the clothes of the present invention. A through-hole 5 obtained by cutting is provided in a joining portion of the members 1 to be joined. The joint portion is in contact with and welded to the other member 2 through the hot melt material 3a. When the members 1 and 2 to be welded match with a member having water repellency, it is difficult to weld the hot melt material 3a particularly on the surface of the member 1, but through holes 5 obtained by cutting the member are provided. As a result, the hot melt material 3a that has been melted by heat flows into the through-hole 5, thereby improving the bonding force between them. That is, as shown in FIG. 5, a large number of ends of the cut member (fiber) are formed, so that a clue that the hot melt material 3a is entangled increases, and the hot melt material 3a wraps around the end of the cut member. By welding, the joining force between the two is improved.

  Moreover, it is preferable that the hole diameter and shape of the said through-hole are the hole diameter and shape which can inscribe a circle | round | yen with a diameter of 2 mm. By doing so, it becomes easy for the adhesive material to flow into the through hole, and the bonding of the through hole described above can be promoted.

  FIG. 2 shows one embodiment of the through hole provided in the clothes of the present invention. Here, the dotted circle shown in the figure represents the size and shape of a circle having a diameter of 2 mm. Each has a variety of shapes, but is characterized by a hole diameter and shape that can inscribe a circle having a diameter of 2 mm. When the hole diameter and shape of the through-hole can inscribe a circle having a diameter of 2 mm, the hot-melt hot-melt material easily flows into the through-hole. Further, the length of the cutting line is increased, which is suitable for joining with the cut member (fiber) described above, and the gap into which the hot melt material flows is also increased.

  The bonding portion having the through hole is bonded from both sides via the bonding portion of the member to be bonded and the adhesive, and the adhesives that are in contact with both surfaces of the bonding portion having the through hole are in the through hole. More preferably, they are welded together. By doing so, not only the joining of the through-hole part mentioned above but the welding of the adhesives contact | abutted on both surfaces of the through-hole is added, and the whole joining force can be improved further.

  FIG. 3 shows an embodiment in which a joining portion having a through hole, which is an embodiment of the garment of the present invention, is welded from both sides via a joining portion of a member to be joined and a hot melt material. The aspect in which the member 2 and the member 4 are welded via hot-melt materials 3a and 3b from both surfaces of the joint portion of the member 1 having a through hole is shown. The melted hot melt materials 3a and 3b flow into the through holes 5 respectively and are welded so as to cross each other in the through holes 5, whereby a stronger bond can be obtained.

  There is no restriction | limiting in particular as a member which comprises the clothes of this invention, The raw material which consists of natural fiber and a chemical fiber is applicable. Moreover, in the said material, resin materials, such as a film and a plastic board, etc. are applicable regardless of structure | tissues, such as a textile fabric, a knitted fabric, and a nonwoven fabric. It is also preferable to apply a material having waterproof performance. Thereby, together with the welding sewing of the present invention, a waterproof garment can be obtained even at the joint portion of the member. Further, composite materials such as fasteners and emblems are also suitable members.

  As means for cutting the member to form the through hole, not only cutting tools such as punches, chisels, cutting knives, and scissors but also die cutting by die cutting can be applied. Also, fusing using ultrasonic waves or high frequencies can be applied. Further, laser cutting or the like that can control the hole diameter and shape of the through-hole relatively easily is easy to form the hole diameter and shape of the through-hole according to the characteristics of the member.

  The hole diameter of the through hole is preferable if it can inscribe a circle having a diameter of 2 mm. By doing so, it is preferable that the molten hot melt material can easily flow into the through hole. As the shape of the through hole, a shape constituted by a curve such as a circle or an ellipse, or a polygonal shape such as a triangle or a quadrangle is conceivable. Further, it may be a complicated shape such as a cross shape or a multi-leaf shape, and a plurality of irregularly shaped cutting holes obtained by combining these shapes may be combined. When the members are joined to each other, the shape of the through hole can be confirmed slightly when viewed from the front side of the member having no through hole, and a three-dimensional surface shape such as embossing can be obtained. For this reason, the shape, size, and arrangement are good when viewed from the front side.

  Hot melt materials include those that apply melted gel-like resin, those that make urethane resin into a sheet, and those that make ethylene vinyl acetate copolymer into a sheet, etc. It is preferable to apply the sheet-like member. The thickness is preferably 50 μm to 200 μm, more preferably 100 to 150 μm. Thereby, it is easy to obtain a balance between adhesive strength and hardness. If it is difficult to obtain an adhesive force, it can be used in a doubled manner. Further, as the hot melt material, an adhesive interlining or an adhesive tape in which an adhesive resin (polyethylene, polyamide, or polyester resin) is attached to a base fabric may be applied.

  When welding the joint part which has a through-hole from both surfaces via a hot-melt material, various aspects can be applied to the member joined from both surfaces according to sewing specifications. The same member may be folded and sandwiched and joined, or another member may be contacted and welded from both sides.

  As a means for heat-welding the hot melt material, one that can apply pressure while heating can be applied. In addition to heat iron, flat plate type hot press, high frequency press, roller type hot press, ultrasonic press and the like can be applied. Preferably, flat plate-type presses that can easily manage and adjust temperature and pressure are suitable. In particular, the high-frequency press is capable of heat welding by internal overheating, and is therefore suitable when using a member that is difficult to transmit heat or when forming a multilayer structure.

  The joining of members by welding of a hot melt material, which is a feature of the garment of the present invention, can be applied to various parts constituting the garment. For example, specifications to weld materials such as brand labels and quality labels to clothing materials, specifications to weld materials such as slide fasteners and hook-and-loop fasteners to clothing materials, and the panels that make up the clothing along the edges Specifications for welding, welding parts by placing them on the panels that make up the clothes, specifications for folding and welding the ends of the clothes as the end of the clothes, specifications for welding hot melt material as a core inside the clothes Etc.

  FIG. 4 shows a welding mode of the slider cap 6 of the fastener 9 as a specific example of application. The slider cap 6 shown in FIG. 4A is disposed at a position where the fastener 9 is closed to the end, and has a function of covering the slider 10 at that position. As a member constituting this, a member in which a through-hole 5 is formed by cutting as shown in FIG. 4B is prepared, and this is welded in half via a hot melt material 8b. Next, as shown in the cross-sectional view of the slider cap 6 portion shown in FIG. 4C, the slider cap 6 having the through hole 5 and the surface material 7 are brought into contact and welded with the hot melt material 8a interposed therebetween. By doing so, the hot melt melted into the through-hole 5 through the slider cap 6 and the front fabric 7, which were difficult to weld with the hot melt material because they were made of the same material as the material of the front fabric 7 having water repellency. By joining the materials 8a and 8b so as to cross each other, they can be joined more strongly.
