Description

  The present invention relates to an improvement in a method for manufacturing a non-sewn garment that can cope with a large movement of a wearer during exercise such as sportswear and swimwear.

  Conventionally, as a so-called non-sewn garment that is manufactured without sewing without using threads and needles, it is a belt-like base material having a fabric that extends and overlaps at least two layers, and the belt-like base material extends in the length direction. A plurality of continuous garment forming portions, and the fabrics stacked in each of the garment forming portions are heat-sealed to form a clothing outline in whole or in part, and cut lines are provided according to the contours; Each garment forming portion is separated from the belt-like base material, and the garment is continuously separated from the separated garment forming portion along the perforation provided in the tear line, thereby providing the garment continuously. A simple clothing providing base material (for example, refer to Patent Document 1) is known.

  In addition, it is a dust-free garment for use in a clean room having each component formed by chemical fiber, and each component is joined by thermal fusion, and the end of the first component and the second component A dust-free garment formed by sewing without joining the first component part and the second component part by heat fusion, and then opening the reinforcing part and heat fusion joining (for example, Patent Document 2, paragraph 0037, second to seventh lines, see FIG. 3 (F).) Is known.

  In the garment according to Patent Document 1, the simple garment providing base material is basically a simple garment, and by directly heat-sealing two pieces of fabric containing a heat-sealing material, Therefore, when the edge part of the garment was cut along the perforation, the edge protruded outward, and the appearance was very bad.

  In addition, if the operation of separating the edge portion along the perforation is mistaken, the clothing may be torn, or a part of the surplus piece may be torn and left on the edge portion, which may damage the appearance. .

As a non-sewn garment that does not have such a defect, there is a dust-free garment according to Patent Document 2.
Since the non-sewn dust-free garment uses the mutual welding of the constituent fabrics, the fabrics are made of chemical fibers suitable for welding. In the case of chemical fibers, it is possible to use nylon fabrics and fabrics that do not have stretchability.

  However, when used in the above-described configuration using a knitted fabric or stretchable fabric that is preferred for sportswear with a large movement of the wearer, problems such as fiber being cut by heat generated during welding are likely to occur, and depending on the invention No knitted fabric or stretch fabric product could be produced. Therefore, even if the expression and description are generally applicable to knitted fabrics and stretchable fabrics, it has been extremely difficult to substantially place and join the knitted fabrics and stretchable fabrics on a horizontal plane. .

  Further, as described above, since the mutual welding of the fabrics that are constituent parts is used, natural fibers that are not suitable for the mutual welding of the fabrics cannot be used.

  Furthermore, in the invention according to Patent Document 2, since it is necessary to align the ends L of the fabric, which are constituent parts cut in advance (see Patent Document 2), in order to weld them, it is very laborious at the time of manufacture. There was a drawback.

  And since the joining part formed by the first welding is crushed from the upper part in the second press, the density of the joining part is increased, and the appearance formed when the joining part is crushed in the vicinity of the joining part. A bad seam pattern is generated, or the fabric is distorted, and irregular irregularities are formed on the fabric. Such an appearance is not only a problem in appearance, but also the wearer may feel a sense of stiffness, which adversely affects comfort.

  From the above circumstances, the present applicant has applied for the invention according to Patent Document 3. According to the invention according to Patent Document 3, a smooth joint surface can be formed and joined, and an irregular unevenness is formed on a poorly formed seam pattern or fabric formed when the joint is crushed in the vicinity of the joint. The present invention has provided an unsewable garment that is extremely smooth, high quality, has a beautiful joint, is easy to manufacture, is low in cost, and is comfortable to wear, and a method for manufacturing the same.

  However, non-sewn garments tend to have lower durability at the joints than normal garment garments. In particular, it is necessary to be able to sufficiently withstand severe use over a long period of time such as repeated washing.

  The present invention has been made in view of the above circumstances, and provides an excellent non-sewn garment that can sufficiently withstand severe use over a long period of time while being a non-sewn garment, and a method for producing the same. Let it be an issue.

In the present invention, stretchable garment-constituting fabrics made of two thermoplastic fibers are stacked on top of each other, the joint edges are temporarily fastened along the joint edges by temporary fastening means, and the fabric is placed from the temporary fastening position. The cut line along the joint edge on the center side is melted by ultrasonic cutting means, and the weld cross sections of the joint edges of the two garment-constituting fabrics are welded and temporarily fixed, with the joint edge as the boundary. Opening two cloth-constituting fabrics, with the joining end faces formed by fusing forming a groove-like opening on the surface side, the thermal bonding tape is brought into contact with the joining edge, and the joining edge and In a method for manufacturing a non-sewn garment in which a thermal adhesive tape is welded and joined, the sewing needle is allowed to enter a gap between a stretchable knitted fabric or a woven fabric by blanking a sewing needle of a sewing machine on which a sewing thread is not attached. Enlarged gap formation to move peripheral fibers The stage, formed along the enlarged gap portion is expanded to the diameter of the needle without cutting the stitch portion or texture portion to the edge of the garment construction fabrics, welding of the joint edge portion and heat the adhesive tape In order to solve the problem, a method for manufacturing a non-sewn garment, characterized in that the melted thermal adhesive tape permeates into the enlarged gap portion and bonds the joint edge and the thermal adhesive tape by bonding. This means.

According to the present invention, the stretchable garment-constituting fabrics made of two thermoplastic fibers are overlapped with each other, and the joint edges are temporarily fastened along the joint edges by temporary fastening means, The cut line along the joint edge at the fabric center side is melted by ultrasonic cutting means, and the weld cross sections of the joint edges of the two garment-constituting fabrics are welded and temporarily fixed, and the joint edge is As a boundary, two clothes-constituting fabrics are opened and the bonding end surfaces formed by fusing form a groove-like opening on the surface side. In the method for manufacturing a non-sewn garment in which a thermal bonding tape is welded and joined, the sewing needle is allowed to enter a gap between a stretchable knitted fabric or a woven fabric by blanking a sewing needle of a sewing machine on which no sewing thread is attached. During enlargement to move the fiber around the sewing needle The forming means to form along the enlarged gap portion is expanded to the diameter of the needle without cutting the stitch portion or texture portion to the edge of the garment structure fabric of the joint edge portion and heat the adhesive tape Since the melted thermal adhesive tape penetrates into the enlarged gap portion by welding and is a method for manufacturing a non-sewn garment in which the bonded edge and the thermal adhesive tape are fixed, the molten thermal adhesive tape is removed from the enlarged gap portion. Entering into the composition fabric and fully bonding the thermal adhesive tape and the clothing composition fabric to strengthen the adhesion, and can withstand long-term severe use such as repeated washing Can be improved.

Further, the enlarged gap forming means is a sewing machine sewing needle, and the enlarged gap is formed by penetrating the garment-constituting fabric by punching only the sewing needle without attaching a sewing thread to the sewing machine sewing needle. The part can be formed very easily and efficiently.

  The non-sewn garment obtained by the manufacturing method described above is a non-sewn garment having a configuration in which the butted ends of stretchable fabrics are joined with a thermal adhesive tape. Since the enlarged gap portion is provided along the edge of the fabric, and the thermal adhesive tape has a configuration in which the enlarged gap portion is melted and solidified, the thermal adhesive tape enters the enlarged gap portion and is melted and solidified. The thermal adhesive tape penetrates deeper into the fabric, and the contact area between the thermal adhesive tape and the fabric is increased, so that sufficient adhesive force can be exhibited.

Two stretchable fabrics made of thermoplastic fibers are stacked on top of each other, the joint edges are temporarily fastened along the joint edges by temporary fastening means, and joined at the center of the fabric from the temporary fastening position. The cut line along the edge is melted by ultrasonic cutting means, and the welded cross-sections of the joining edges of the two clothing constituent fabrics are welded to form a temporary fixing state. Open the constituent fabric, and with the joining end faces formed by fusing forming a groove-like opening on the surface side, the thermal bonding tape is brought into contact with the joint edge, and the joint edge and the thermal adhesive tape are In the method of manufacturing a non-sewn garment to be welded and joined, the sewing needle is allowed to enter a gap between a stretchable knitted fabric or a woven fabric by blanking a sewing needle of a sewing machine that is not attached with a sewing thread, and fibers on the periphery of the sewing needle. By the enlarged gap forming means to be moved To form along the enlarged gap portion is expanded to the diameter of the needle without cutting the stitch portion or texture portion to the edge of the garment construction fabric, the fusion bonded in the joint edge portion and heat the adhesive tape Since the melted thermal adhesive tape penetrates into the enlarged gap portion to fix the joining edge and the thermal adhesive tape, the melted thermal adhesive tape passes through the enlarged gap portion into the garment constituting fabric. By entering and fully bonding the thermal adhesive tape and the garment composition fabric, the adhesion will be strengthened, and the excellent durability that can withstand severe use over a long period of time such as repeated washing will be improved Thus, an excellent method for manufacturing a non-sewn garment capable of forming the enlarged gap portion very easily and efficiently has been realized.

FIG.

  As shown in FIG. 6, the non-sewn garment according to the embodiment of the present invention is sportswear formed by joining a plurality of clothes constituting fabrics having elasticity. As shown in FIG. 1, the joining method of the joining end surfaces of the garment constituent fabric 1 and the garment constituent fabric 2 will be described.

  First, as shown in FIG. 1 (a), the surface of two pieces of the garment constituting fabric 1 and the garment constituting fabric 2 are overlapped to face each other, and as shown in FIG. Thus, one end piece of the garment-constituting fabric 1 and the garment-constituting fabric 2 is fixed by temporarily attaching and positioning with the temporary fixing thread 3.

In the garment constituting fabric 1 and the garment constituting fabric 2 temporarily attached with the temporary fixing thread 3, as shown in FIG. 2 (a), a predetermined interval is provided from the temporary fixing thread 3 toward the other end piece. After having, the three-needle sewing machine in a state where the temporary fixing thread 3 has been removed is used to perform idle driving. That is, the enlarged gap portion 4 in which the stitch portion or the weave portion is enlarged by the thickness of the sewing needle is efficiently formed by the plurality of sewing needles attached to the three-needle sewing machine. In this embodiment, about 18 enlarged gap portions 4 are formed at a pitch of 1 cm in the longitudinal direction.

In the first embodiment, as shown in FIG. 8, the sewing needle N enters the gap of the stretchable fabric (FIG. 8 (a)) (FIG. 8 (b)), so that the fibers on the periphery of the sewing needle N There moved, pull the needle N (to FIG. 8 (c)) that is to form the enlarged gap portion 4 of the diameter portion of substantially needle N.

As shown in FIG. 2 (b), the garment constituting fabric 1 and the garment constituting fabric 2 in which the enlarged gap portion 4 is formed are fused at the edge of the enlarged gap portion 4 on the side having the temporary fixing thread 3 side. The line 5 is melted by the ultrasonic roller 6 or the like.
At this time, the welded cross sections of the joining edge portions 1a and 2a of the two clothes constituting fabrics 1 and 2 are welded to be temporarily fixed. In addition, as shown to Fig.3 (a), the part away from the fusion | melting part among joining edge parts 1a and 2a is hardly influenced by the heat | fever at the time of a fusion | melting, The said two clothing constituent fabrics 1, 2 And does not weld. Further, the surplus piece 7 generated by the fusing is not used in the manufacturing process according to the present embodiment, but can be separately recycled.

  Next, as shown in FIG. 3B, the surplus piece 7 is removed, and the two pieces as shown in FIG. 4A are centered on the boundary line of the temporarily joined joint edge portions 1a and 2a. Open the clothes constituting fabrics 1 and 2. By opening the clothes constituting fabrics 1 and 2, the surface is exposed to the outside, and a groove-shaped opening 8 is formed on the back side between the two pieces of clothing constituting fabrics 1 and 2.

Then, as shown in FIG. 4 (b), the thermal adhesive tape 9 is contacted from the back surface side so as to straddle each joint edge 1a, 2a and to cover the enlarged gap portion 4, The joining edge portions 1a and 2a and the thermal adhesive tape 9 are joined by the thermal welding means in a state where the joining end faces face each other or abut against each other. At this time, it is necessary that the clothes constituting fabrics 1 and 2 and the thermal adhesive tape 9 are completely heat-welded.
Moreover, in the present Example 1, the said thermobonding tape 9 is the structure which impregnated the adhesive agent etc. in the tape part, and made the stretchability of the width direction of the thermobonding tape smaller than the stretchability of the clothes structure cloth in the same direction. Something is used. In addition, the structure of the heat bonding tape 9 can also be made into the structure which soaked the hot-melt-adhesive etc. from the tape part at the time of heat welding.

  Thus, as shown to Fig.5 (a), the said clothing constituent fabrics 1 and 2 are comprised by non-sewing.

  In a conventional non-sewn garment, the thermal adhesive tape 9 is impregnated with an adhesive or the like, or the stitch portion of the fabric thermally welded by soaking the hot melt adhesive or the like from above the tape portion at the time of thermal welding or The adhesive is fixed when the adhesive penetrates into the textured portion.

On the other hand, in the non-sewn garment in the present invention, as shown in FIG. 5 (b), not only the stitch portion or the weave portion of the fabric but also the three-needle sewing machine with the temporary fixing thread 3 removed. was ineffective, by a plurality of needles, in the enlarged gap portion 4 where the stitch portion or weave portion was enlarged by the thickness of the sewing needle, such as an adhesive 10 is fixed to penetrate.
That is, by providing the enlarged gap portion 4, adhesive or the like penetrates into the enlarged gap portion 4, and the volume in the enlarged gap portion 4 increases, thereby increasing the fixing force.

The method for manufacturing a non-sewn garment according to the second embodiment of the present invention further includes a process after the method for manufacturing the non-sewn garment according to the first embodiment is completed. Specifically, the state shown in FIGS. 5 (a) and 5 (b), that is, straddling the joining edge portions 1a and 2a and covering the enlarged gap portion 4 from the back side. After the state in which the thermal bonding tape 9 is abutted and the joint edge portions 1a, 2a and the thermal adhesive tape 9 are joined by the thermal welding means in a state where the joint end faces face each other or come into contact with each other, as shown in FIG. Also on the other end surface facing each other, the thermal adhesive tape 9 is brought into contact and joined by thermal welding means.

  According to the method for manufacturing a non-sewn garment according to the second embodiment, the fixing force can be further increased by joining the thermal adhesive tape 9 to both end faces of the garment constituting fabrics 1 and 2.

In the second embodiment, as shown in FIG. 9, when the sewing needle N enters the gap of the knitted fabric (FIG. 9A) (FIG. 9B), the fibers on the periphery of the sewing needle N are changed. By moving and pulling out the needle N (FIG. 9C), an enlarged gap portion 4 corresponding to the diameter of the sewing needle N is formed.

(Strength test for Examples 1 and 2 of the present invention)
The strength test shown below was performed on the existing non-sewn garment and the non-sewn garment of the present invention to confirm whether there was any abnormality such as peeling.
(Test method)
(A) Tensile strength test when finished product: JIS L 1018 grab method (b) Tensile strength test after Acceler rotor treatment (JIS L 1018 grab method)
The above two types shall be performed.

  In the accelerator rotor process, two 10 cm square samples are folded in two so that the bonding surface is inside, and are sewn so that the end does not exceed 4 mm. The test sample was immersed in a 0.01% nonionic surfactant aqueous solution for 10 minutes, rinsed with ion-exchanged water, and lightly squeezed two test pieces were applied to an accelerator rotor type tester, and the test sample was 10 at a speed of 2000 rpm. It means to put on the testing machine for a minute. By this processing, the conditions corresponding to the clothes constituting fabrics that have been repeatedly washed for each test piece are reproduced.

The test piece A is a test piece joined by using a heat-adhesive tape having poor stretchability on one side of the garment constituting fabric. (Conventional example.)
The test piece B is a test piece joined using a heat-adhesive tape having stretchability in the width direction on one side of the garment-constituting fabric, and the test piece C corresponds to the invention according to Patent Document 3, and the stretch in the width direction. This is a test piece in which a heat-adhesive tape having properties is used on one side of a joint part of a garment constituting fabric. (Conventional example corresponding to the invention according to Example 1 of the present invention)
The test piece C is a test piece joined using a heat-adhesive tape having stretchability in the width direction on both sides of the garment constituting fabric. (Conventional example corresponding to the invention according to Example 2 of the present invention)
The test piece D is a test piece according to an embodiment of the present invention, and is an test piece in which an enlarged gap portion is formed in the joint portion of the garment-constituting fabric and a thermal adhesive tape is provided on one side of the joint portion. (This corresponds to the invention according to Example 1 of the present invention.)
The test piece E is a test piece according to an embodiment of the present invention, and is a test piece in which an enlarged gap portion is formed at the joint portion of the garment-constituting fabric and a thermal adhesive tape is provided on both sides of the joint portion. (This corresponds to the invention according to Embodiment 2 of the present invention.)

表中の「チャック切れ」とは、接着部分の剥離ではなく、生地自体の破損である。 (Test results)
The test results are shown below.

“Chuck out” in the table is not the peeling of the bonded portion but the breakage of the fabric itself.

(A) Tensile strength test when finished product In all the samples A to E, the chuck is broken. That is, even if the fabric itself is damaged, the joint is not peeled off, and it can be determined that the test pieces A to E have excellent durability when the product is finished.

(B) Tensile strength test after accelerator rotor treatment Test piece A has a tensile strength of about 128 N and does not have sufficient durability.
Test piece B has a tensile strength of about 206N. Moreover, the tensile strength of the test piece D according to the present invention in which the enlarged gap portion is added to the configuration of the test piece B is 227N. For this reason, the improvement of the tensile strength of about 10% from the test piece B is recognized.
Specimens C and E cause chuck breakage. That is, even if the fabric itself is damaged, the joint portion does not peel off, and it can be determined that the test pieces C and E have excellent durability when the product is finished.

  As described above, the test piece D of the present invention, which is an improvement of the test piece B, was able to obtain an improvement in tensile strength of about 10% by forming an enlarged gap portion. Moreover, it turned out that the test piece E of this invention has the outstanding durability. In particular, the test piece D is a test piece provided with a thermal adhesive tape on one side of the joint portion, and has a structure that is optimal for the comfort of a non-sewn garment provided with a thermal adhesive tape only on one side and has a large tensile strength. The improvement was realized.

As the means for forming the enlarged gap portion in the present invention, not only the three-needle sewing machine disclosed in the embodiment, but also a normal sewing machine (only one sewing needle ) may be used, or other plural sewing needles may be used. The sewing machine which has can also be used. By simultaneously blanking with a plurality of sewing needles , a large number of enlarged gap portions can be formed efficiently.

  In Example 1, the relationship between the melt amount of the thermal adhesive tape and the thickness of the clothing constituent fabric of the non-sewn garment is such that the melted thermal adhesive tape does not flow out to the back of the clothing constituent fabric. In addition, the resin that has been solidified by cooling after melting (on the heat-adhesive tape) does not cause discomfort due to contact with the skin.

  In the present embodiment, the heat welding means for joining the joining edge portion and the warp knitting reinforcing thermal adhesive tape is performed by a seam press. However, in the present invention, not only a seam press but also a heating by an iron (for example, a normal hand iron), a thermocompression pressing by an embossing press machine, or a partial ultrasonic welding by a pressure roller and a horn, etc. It is also possible to combine a plurality of these heat welding means such as performing ultrasonic welding after heating with an iron.

Further, according to the first embodiment of the present invention, as shown in FIG. 2 (a), the enlarged gap portion is formed by the enlarged gap portion forming means at the stage before the two pieces of clothing constituting fabric are opened. The enlarged gap portion is formed by penetrating the two garment-constituting fabrics overlapped to enlarge the stitch portion or the woven portion of the garment-constituting fabric, but the present invention is not limited to this, for example, In the stage of FIG. 2 (a), the enlarged gap forming means is not used in the state where the two cloth-constituting fabrics are opened with the joining edge shown in FIG. 4 (a) as a boundary without forming the enlarged gap. An enlarged gap portion can also be formed.
By forming the enlarged gap portion in a state where the two clothes constituting fabrics shown in the first embodiment are overlapped, it is possible to open the two pieces of the clothing constituting fabric with respect to a single operation of forming the enlarged gap portion. In this case, it is possible to form twice as many enlarged gap portions, which is excellent in terms of high working efficiency.
On the other hand, in the stage of FIG. 2 (a), without forming the enlarged gap portion, the enlarged gap portion forming means is opened in the state where the two clothes constituting fabrics are opened with the joining edge portion shown in FIG. 4 (a) as a boundary. Therefore, by forming the enlarged gap portion, the enlarged gap portion is formed immediately before the thermal bonding tape is welded to the joining edge portion, so that the state where the enlarged gap portion is formed can be maintained more reliably. More reliable welding can be performed.

  The seam press which is the heat welding means in the present embodiment uses a hot air type tape applicator, and the hot air type tape applicator is applied to the warp knitted reinforcing thermal adhesive tape stacked on each garment joining fabric. The hot-bonding tape for warp knitting reinforcement is melted and solidified by blowing hot air from the nozzle.

  When performing partial ultrasonic welding with a pressure roller and a horn (not shown), the horn H which is an ultrasonic transmission means of the ultrasonic welding machine and the pressure roller R for forming the welding portion are used. The warp knitting reinforcing thermal adhesive tape and the two pieces of clothing constituting fabric are sandwiched, and the warp knitting reinforcing thermal adhesive tape is welded to the clothing constituting fabric. In Example 1, the entire joining edge is sequentially ultrasonically welded, but a protrusion is formed on the pressure roller, and the garment-constituting fabric and the warp knitting reinforcing thermal adhesive tape are welded only at the protrusion. You can also.
