Description

[Technical field]

[0001] The present invention relates to textile products constructed using adhesives. [Background technology]

[0002] In recent years, there have been concerns about the adverse effects on ecosystems caused by plastic waste in oceans and rivers being ingested by living organisms. Microplastics, which are of concern for their adverse effects on ecosystems, are mostly made up of illegally discarded plastic containers that have been broken down into micro-sized plastic pieces by ultraviolet light, etc. Also, although in small amounts, plastic laundry debris is generated when textile products are washed, and is collected by the drainage filters of washing machines and even at sewage treatment plants.

[0003] On the other hand, as technological advances such as ultra-thin fibers, more complex sewing, and softer woven fabrics have led to an increase in laundry debris and a tendency for it to become finer, laundry bags with improved fiber debris collection capabilities have been proposed as a means of collecting fiber debris that falls off during washing (for example, Patent Document 1). However, no textile products have been proposed to reduce the amount of fiber debris generated during washing. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2019-505351 Summary of the Invention [Problem to be solved by the invention]

[0005] The object of the present invention is to provide a textile product containing synthetic fibers, which are the source of laundry debris, that reduces the amount of laundry debris generated by changing the concept from the conventional method of collecting laundry debris on the assumption that it will be generated. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the textile product of the present invention is a textile product containing synthetic fibers, which is made of an elastic fabric and has an end of the fabric consisting of a joint formed by folding the end of the fabric twice to form a triple structure, the joint being located at the end of the fabric and comprising: a first folded-back region located in the middle of the triple structure; a second folded-back region connected to the first folded-back region and located on the outside of the triple structure; a third region connected to the second folded-back region and located on the outside of the triple structure; a first adhesive that is applied intermittently in a single or double row and bonds the first folded-back region and the second folded-back region; and a second adhesive that is applied intermittently in a single or double row and bonds the first folded-back region and the third region, wherein the first adhesive or the second adhesive is applied so as to contact a position within 1.0 mm from the end of the fabric.

[0007] In the textile product of the present invention, the edge of the fabric in the first folded region is folded the law of nature It is preferable that the second folded region be in contact with the boundary line between the second folded region and the third region obtained by the turn.

[0008] In the textile product of the present invention, it is preferable that an edge of the fabric in the first folded region is fused.

[0009] Alternatively, in the textile product of the present invention, it is preferable that an edge of the fabric in the first folded region is sewn with an overedge.

[0010] In the textile product of the present invention, it is preferable that the turn-up length of each of the first turn-up region and the second turn-up region is in the range of 3 mm to 10 mm.

[0011] In the textile product of the present invention, the first and second adhesives are preferably applied in the form of dots having a diameter of 0.3 to 1.0 mm. Effect of the Invention

[0012] According to the present invention, in order to suppress the generation of fiber debris falling off from the ends of the fabric of a textile product, an adhesive is used to form the joints so that the ends of the fabric are not exposed, thereby making it possible to provide a textile product that generates less laundry debris and is flexible and does not feel tight.

[Diagram 3] 1A and 1B are a transparent plan view and a cross-sectional view showing a configuration of an embodiment of the present invention. [Figure 4] FIG. 1 is a diagram showing one embodiment of the present invention; [Diagram 5] FIG. 1 is a cross-sectional view showing a textile product according to a prior art. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention (hereinafter, referred to as "embodiment") will be described with reference to the accompanying drawings. Note that the drawings are merely schematic. (Embodiment) 4 is a diagram showing a schematic diagram of a textile product 1 according to an embodiment of the present invention. The textile product 1 shown in the figure is an example of a short-sleeved undergarment top, and has openings 2, 3, and 4 for passing the head, arms, and torso.

[0015] The textile product 1 is made of a stretchable fabric. For example, knitted fabric materials such as circular knitting and warp knitting provided as general clothing materials have the stretchability required for implementing the present invention and are not limited thereto. In addition, even if it is a woven fabric material, materials having the stretchability required for clothing are suitable for the present invention.

[0016] FIG. 1 is a cross-sectional view showing the configuration of the end of the fabric of a textile product 1 according to an embodiment, FIG. 2 is a cross-sectional view showing the procedure for constructing the end of the fabric of a textile product 1 according to an embodiment in the order of (a) to (c), and FIG. 3 is a plan view showing the end of the fabric of a textile product 1 according to an embodiment in a see-through manner and its cross-sectional view.

[0017] The textile product 1 of the present invention has an edge of a fabric that is made up of a joint portion that is formed by folding the edge of the fabric twice to form a triple structure. The joint portion is located at the edge of the fabric and includes a first folded-back region C1 located in the middle of the triple structure, a second folded-back region C2 that is connected to the first folded-back region C1 and located outside the triple structure, a third region C3 that is connected to the second folded-back region C2 and located outside the triple structure, a first adhesive B1 that is intermittently provided in a single or double row and bonds the first folded-back region C1 and the second folded-back region C2, and a second adhesive B2 that is intermittently provided in a single or double row and bonds the first folded-back region C1 and the third region C3.

[0018] The joint of the textile product 1 of the present invention is such that the end E of the fabric is folded inside the triple structure, and the end of the fabric is not exposed to the outside. In addition, since there are no seams from sewing, which is commonly used, fiber waste that falls off from the end of the fabric or sewing thread is reduced, and a textile product with less laundry waste can be obtained. Furthermore, by configuring the product with adhesive applied intermittently, it is possible to obtain clothing that has a good texture and does not feel tight, without losing the suppleness and elasticity of the fabric.

[0019] When a washing test is carried out on one piece of the textile product according to the ISO 6330 C4N method, the amount of fiber debris adhering to a collection bag attached to a drain hose after the test can be collected using a membrane filter to be 40 (mg / textile product) or less.

[0020] In the textile product of the present invention, the width of the joint may be any width necessary for seam allowance or fold allowance to constitute a typical garment. For example, in the openings 3 and 4 of the cuffs and hem of the textile product 1, a folding amount of about 10 to 30 mm is considered, but in the opening 2 of the collar which is formed by a curve, if the folding width is too large, pulling will occur due to the difference between the inner and outer circumference of the curve, so it is preferable to keep it small, around 3 mm to 10 mm.

[0021] In the textile product of the present invention, the first adhesive B1 and the second adhesive B2 are arranged in a single or double row in a form in which they are applied intermittently. The preferred range of the application area of ​​the first adhesive B1 and the second adhesive B2 varies depending on the structure and thickness of the fabric A constituting the garment 1. If the shape of the application of the first adhesive B1 and the second adhesive B2 is a dot shape with a diameter of about 1.0 to 2.0 mm, a relatively strong adhesive strength can be obtained, but if the fabric A is thin, the adhesive may seep out to the front side of the fabric A and become noticeable, which may impair the appearance, so it is preferable to apply a dot shape with a small diameter within a range in which the required adhesive strength can be obtained. For example, in the case of an inner fabric with a thickness of about 0.5 to 0.8 mm, it is preferable that the dot diameter is about 0.6 to 1.0 mm, since the first adhesive B1 and the second adhesive B2 are less likely to seep out to the front side of the fabric A. When the material A is thinner, with a thickness of about 0.3 to 0.5 mm, it is preferable that the dot diameter is about 0.3 to 0.6 mm, since the seepage of the first adhesive B1 and the second adhesive B2 is less noticeable.

[0022] In the textile product 1 of the present invention, the first adhesive B1 and the second adhesive B2 are applied in a circular shape in Fig. 3, but the present invention is not limited to this. Any shape may be used as long as the first adhesive B1 and the second adhesive B2 are repeatedly applied in an intermittent separated state, and if they are not continuous, they may be linear, or may have a geometric shape such as a triangle, a square, an ellipse, or a combination of these.

[0023] In the textile product of the present invention, the resins constituting the first adhesive B1 and the second adhesive B2 are preferably synthetic resins rather than natural resins, and among them, thermoplastic resins are more preferable. For example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyethersulfone, polyetheretherketone, polyimide, polyamideimide, and other polymer compounds are not particularly limited, and various materials can be used as long as they are made of polymer compounds.

[0024] In the textile product of the present invention, the resin constituting the first adhesive B1 and the second adhesive B2 is preferably a moisture-reactive hot melt. When the resin is a moisture-reactive hot melt, the resin softens or melts and penetrates between the structures of the bonded portion, and after cooling and solidifying, it reacts with the surrounding moisture to proceed crosslinking, and a joint excellent in heat resistance and solvent resistance can be formed, and even a small amount of adhesive applied in a dot shape can obtain strong adhesive strength. In addition, the resin constituting the first adhesive B1 and the second adhesive B2 is preferably a heat-reactive hot melt. When the resin is a heat-reactive hot melt, it can form a joint excellent in heat resistance and solvent resistance even after cooling and solidifying. If a resin that has elasticity after being fixed to the fabric as another characteristic of the resin is used, clothing with a good texture can be obtained without losing the flexibility and stretchability of the fabric.

[0025] In the textile product 1 of the present invention, it is preferable that an end E of the fabric in the first folded-back region C1 contacts a boundary line F between the second folded-back region C2 and the third region C3 obtained by folding back.

[0026] In this case, the boundary line F between the second folded region C2 and the third region C3 obtained by folding corresponds to the folding line, and the edge E of the fabric preferably contacts the inside of the folding line. Generally, most of the fiber waste that falls off from a textile product is generated from the edge of the cut fabric. Even if the fabric is cut in a straight line, the fiber bundles that make up the fabric structure are cut in the middle of the undulation, generating short fiber-like fiber bundles that are not bound by the fabric structure. These become fiber waste by falling off from the fabric structure, but as in the textile product 1 of the present invention, by configuring the connection part so that the edge E of the fabric in the first folded region C1 contacts the boundary line F between the second folded region C2 and the third region C3 obtained by folding, the cut short fiber-like fiber bundles are prevented from falling off from the fabric structure, and the generation of fiber waste can be suppressed.

[0027] In the textile product 1 of the present invention, it is preferable that the end E of the fabric in the first folded-back region C1 is fused. By fusion-cutting the end E of the fabric, the fiber bundles constituting the fabric structure and the short fiber-like fiber bundles generated by fusion and not bound by the fabric structure are partially fused at the single fiber level, and being bound by the fabric structure prevents the fiber bundles from falling off, thereby suppressing the generation of fiber waste.

[0028] The cutting method may be any commonly available cutting technique, and ultrasonic cutting, laser cutting, high frequency cutting, etc. are preferable.

[0029] Alternatively, in the textile product 1 of the present invention, it is preferable that the fabric edge E of the first folded-back region C1 is overlocked. Generally, overlocking is used to prevent fraying of the fabric edge when the fabric is exposed, but in the textile product of the present invention, where the fabric edge is folded back twice to form a triple-structured joint, it is possible to effectively prevent short fiber bundles that are not bound by the fabric structure generated by cutting from falling off from the fabric structure, thereby suppressing the generation of fiber waste.

[0030] The overlocking may be performed by a commonly available overlocking stitch, and is preferably performed by a single-needle overlocking sewing machine. The sewing thread used is preferably a general filament sewing thread or spun sewing thread, but the looper thread that wraps the end E of the fabric is preferably a woolly sewing thread. By using the woolly sewing thread, the single fibers of the woolly thread spread out and wrap the end E of the fabric, preventing the single fiber bundles from falling off the fabric structure and suppressing the generation of fiber waste.

[0031] In the textile product 1 of the present invention, as shown in Fig. 3(b), the first adhesive B1 that bonds the first folded region C1 to the second folded region C2, or the second adhesive B2 that bonds the first folded region C1 to the third folded region C3, is preferably applied so that the adhesives come into contact with each other near the end E of the fabric. By applying the adhesives so that they come into contact with each other near the end E of the fabric, more adhesive is distributed along the end E of the fabric, making it possible to bond more of the monofilament-like fiber bundles generated by cutting, and preventing them from falling off from the fabric structure, thereby suppressing the generation of fiber waste.

[0032] 3(a), the first adhesive B1 or the second adhesive B2 is applied near the end E of the fabric, and by applying it so as to be in contact with the end E of the fabric, the short fiber-like fiber bundles that are not bound by the fabric structure generated by cutting are fixed to the fabric structure, and it is possible to effectively prevent the fiber bundles from falling off from the fabric structure and suppress the generation of fiber waste. The first adhesive B1 or the second adhesive B2 is preferably applied so as to be in contact with the end E of the fabric, but since the effect can be obtained if the single fiber-like fiber bundles that are not bound by the fabric structure generated by cutting can be fixed, it is possible to prevent the fiber bundles from falling off from the fabric structure and suppress the generation of fiber waste by applying it so as to be in contact with a position within 1.0 mm, preferably within 0.5 mm, from the end E of the fabric.

[0033] The textile product 1 of the present invention is preferably applied to general underwear such as that shown in Fig. 4, innerwear with cups, as well as underwear such as camisoles and tank tops. It can also be applied to outerwear such as T-shirts and cut-and-sewn tops. Furthermore, it can be applied to all textile products such as daily necessities such as towels, handkerchiefs, sheets, and pillowcases, and household goods such as eco-bags and cushion covers, and is not limited thereto.

[0034] Although the embodiments for carrying out the present invention have been described above, the present invention should not be limited to the above-described embodiments. EXAMPLES

[0035] The evaluations in the examples were carried out according to the following methods. (Flexibility / tightness of joints) The evaluation was performed visually and by touch according to the following criteria.

[0036] ○: Flexible and doesn't feel tight ×: I'm concerned about the suppleness and tightness △: Between ○ and ×. (Amount of laundry debris) The amount of laundry debris was measured according to the following procedure. [i] First, wash the laundry in the washing machine without any laundry, load or detergent, according to the ISO 6330 C4N method, and clean the washing machine. [ii] A collection bag made from a nylon screen NY10-HC (Flon Industries Co., Ltd.) with a mesh size of 10 μm is attached to the drain of the washing machine, and one textile product to be evaluated is placed in the washing machine and washed according to the ISO 6330 C4N method, except that no detergent or load cloth is used. After washing, the fiber debris attached to the nylon screen is collected with pure water and suction filtered using a polycarbonate membrane filter (K040A047A, Advantech Toyo Co., Ltd.) whose weight has been measured in advance. The polycarbonate membrane and fiber debris after filtration are dried at 105°C for 1 hour and weighed. The difference from the weight before filtration is taken as the amount of laundry debris (mg / textile product). Example 1 A textile product 1 was produced as a general undergarment as shown in FIG. 4, which is made of bare jersey material made of 90% nylon and 10% polyurethane. The fabric parts constituting the textile product 1 were pretreated before assembling the textile product 1, with respect to the openings 2, 3, and 4, which are the ends of the fabric, and the shoulders 5, sleeve attachments 6, and sides 7, which are the panel joints. For the fabric parts cut by a normal cutting blade, a triple-structure joint was formed with a width of 6 mm for the first folded-back region C1, the second folded-back region C2, and the third region C3, as shown in FIG. 1(a). In addition, for the joint, as shown in FIG. 2, a dot-shaped first adhesive B1 with a diameter of 0.8 mm (diameter of 1.0 mm after bonding) was applied to the folded-back side surface A1 of the second folded-back region C2 parallel to the end of the fabric, and the first folded-back region C1 was folded back. At this time, the first adhesive B1 was applied in two rows, the distance between the centers of the rows was 2.0 mm, and the pitch in the longitudinal direction of the rows was also 2.0 mm, as shown in FIG. 3(a). The first adhesive was a moisture-curing polyurethane hot melt resin. Next, the same type of second adhesive B2 as the first adhesive was applied to the surface A2 opposite to the folded surface of the folded first folded region C1, and the second folded region was folded to form a fabric part having a triple-structure joint. At this time, the end E of the fabric was not in contact with the boundary line F between the second folded region C2 and the third region C3, and a gap of 1 to 2 mm was left. As shown in FIG. 3(a), the second adhesive B2 was applied to the same position as the first adhesive B1 in a see-through view, with the same size, resin, and application pattern as the first adhesive B1. Next, a heated and pressurized adhesive press was performed in a flat-plate adhesive press to complete the fabric part that constitutes the textile product 1. Finally, the fabric parts were joined together to obtain the textile product of the present invention according to Example 1. In Example 1, a moisture-reactive hot-melt PU resin with a viscosity of about 12,000 mPa·s at 120°C was used as the adhesive.

[0037] The obtained textile products were evaluated for the tension and texture of the joints, and the amount of laundry debris generated after washing. The results are shown in Table 1. Example 2 The textile product of Example 2 of the present invention was obtained in the same manner as Example 1, except that the end E of the fabric was configured to be in contact with the boundary line F between the second folded region C2 and the third region C3, as shown in (b) of Figure 1. Example 3 A textile product of Example 3 of the present invention was obtained in the same manner as in Example 1, except that the fabric parts were cut using a laser cutter and the edge E of the fabric was melt-cut. The laser cutter used was a #CMA-1610T type cutter manufactured by Yueming Co., Ltd. Example 4 As shown in (c) of Fig. 1, the textile product of Example 4 of the present invention was obtained in the same manner as in Example 1, except that the edge E of the fabric was overheard. The overheard part H1 was sewn to a width of 2 mm with a single-needle, three-thread overheard sewing machine, and polyester filament yarn #60 was used for the needle thread and polyester woolly yarn 110 / 2 was used for the looper thread. Example 5 As shown in (b) of Figure 3, the textile product of Example 5 of the present invention was obtained in the same manner as in Example 1, except that the first adhesive B1 bonding the first fold-back region C1 to the second fold-back region C2 and the second adhesive B2 bonding the first fold-back region C1 to the third fold-back region C3 were applied so that the adhesives were in contact with each other in the longitudinal direction at a position including the end E of the fabric. Comparative Example 1 The textile product of Comparative Example 1 of the present invention was obtained in the same manner as in Example 1, except that, as a pretreatment of the fabric parts before assembling Comparative Example 1, the fabric edges were sewn using a twin-needle flat stitch sewing machine, which is a common conventional sewing machine technique, as shown in Fig. 5. At this time, the edge E of the fabric was positioned so as to be exposed 1 mm from the seam H2 of the twin-needle flat stitch, as in common textile products.

[0038] The Examples and Comparative Examples obtained as described above were evaluated, and the results are shown in Table 1. As is clear from Table 1, the Examples of the present invention resulted in a reduction in the generation of laundry debris without losing the suppleness and good texture of the fabric due to the three-layer structure of the fabric edge and the application of intermittently applied adhesive and the processing of the fabric edge. In contrast, in the Comparative Examples, the fabric edge was exposed to the outside, resulting in a large amount of laundry debris, and even though it had a three-layer structure, the suppleness of the fabric was lost due to the tape-like adhesive, resulting in a feeling of tension.
