Description

Laminated padding sheet, its manufacturing method and padding structure using the same

[0001] The present invention relates to a laminated padding sheet, a method for producing the same, and a padding structure using the same.

[0002] The feathers used to fill feather products such as down comforters and down jackets are generally from waterfowl. Waterfowl include geese, ducks, and wild eiders that inhabit the coastlines of the Arctic Circle. Down includes both down, which is the equivalent of chest hair, and feathers, both of which are used in feather products. Down is sourced in Central Europe, including Poland and Hungary, Northern Europe, including the Scandinavian Peninsula, and China. Feathers are bulky and warm, making them a high-quality material for down comforters and down jackets. However, natural feathers are dependent on waterfowl, and their supply is limited. Furthermore, supply fluctuates due to natural conditions and diseases (such as avian influenza). Furthermore, there are limitations to capturing wild birds from a conservation perspective. Furthermore, natural feathers can cause unpleasant odors if not washed thoroughly. Therefore, it is necessary to remove odor-causing contaminants in advance and maintain a consistent level of cleanliness and oxygen count, which indicate the degree of feather cleaning. Additionally, there is a fundamental problem: down products such as down comforters and down jackets are not easily laundered. Therefore, many proposals for filling have been made, including long-fiber filling consisting of core and filament yarns. Methods for filling long-fiber filling into insulating structures such as down jackets include creating gaps in the insulating structure through which long-fiber filling can be inserted and inserting the long-fiber filling, or laying the long-fiber filling on top of the lining fabric, layering the outer fabric, quilting the laminate, and securing the long-fiber filling between the lining and outer fabrics. Because these methods require specialized methods for using long-fiber filling, a need exists for a method that can be easily applied to existing clothing manufacturing processes.

[0003] Patent Document 1 discloses a thermal insulation material for clothing, comprising an integrated bulkiness-retaining layer made of synthetic fibers and a microporous membrane layer having a microporous membrane. The bulkiness-retaining layer uses bulky yarn, and the microporous membrane layer uses a microporous membrane, particularly a meltblown nonwoven fabric, in which 80% or more of the micropores have a pore size of 5.0 μm or less. Patent Document 2 discloses a long-fiber cotton sheet, in which aligned long-fiber cotton sheets are placed on the front and back sides of a thermal adhesive sheet, and the long-fiber cotton sheet is re-polymerized (a three-layer state with the thermal adhesive sheet interposed), and the long-fiber cotton sheet is passed through a pair of heat rolls to heat-bond first and second layers of long-fiber cotton sheets to both sides of the thermal adhesive sheet, thereby enhancing the integrity. In Patent Document 3, the present inventors disclose a laminated padding sheet, which can be uniformly and automatically arranged to form a planar laminated padding sheet, and a padding structure using the same. It is proposed that the padding be folded and laid out, sandwiched between two pieces of fabric, and then sewn together.

[0005] However, the conventional technology has the problem that the long fiber filling is easily caught on various objects, which causes it to fray and makes it difficult to handle, making it difficult to easily apply to existing clothing manufacturing processes.

[0006] In order to solve the above problems, the present invention provides a laminated padding sheet that is easy to handle, can be easily applied to existing clothing manufacturing processes, has high bulk and good flatness, a manufacturing method thereof, and a padding structure using the same.

[0007] One embodiment of the laminated padding sheet of the present invention is a laminated padding sheet including a long fiber padding layer and a fiber sheet layer, wherein the long fiber yarns constituting the long fiber padding layer are composed of at least core yarns and filament yarns, which are integrated together, a plurality of the long fiber yarns are arranged in the longitudinal direction to form a sheet, and the fiber sheet layers are laminated on both sides of the sheet-like long fiber padding layer, and the laminated padding sheet is quilted with quilting yarns in the thickness direction and across the longitudinal direction of the long fiber yarns.

[0008] Another embodiment of the laminated padding sheet of the present invention relates to a method for manufacturing the laminated padding sheet, which comprises aligning a plurality of long fiber yarns, each of which is composed of at least a core yarn and an effect yarn and in which the core yarn and the effect yarn are integrated, and arranging them in parallel in the length direction to form a long fiber padding layer, laminating fiber sheet layers on both sides of the long fiber padding layer, quilting them with quilting yarn in the thickness direction and across the length direction of the long fiber yarn, and winding up the laminated padding sheet.

[0009] Yet another embodiment of the laminated padded sheet of the present invention relates to a fibrous structure including the laminated padded sheet.

[0010] The laminated padding sheet of the present invention has a plurality of long fiber yarns arranged longitudinally to form a sheet, and fiber sheet layers are laminated on both sides of the sheet-like long fiber padding layer, and the sheet is quilted with quilting yarn in the thickness direction and transversely to the longitudinal direction of the long fiber yarns. This provides a laminated padding sheet and its manufacturing method, as well as a padding structure using the same, that are easy to handle, can be easily applied to existing clothing manufacturing processes, and are highly bulky and flat. In other words, by quilting with quilting yarn transversely to the longitudinal direction of the long fiber yarns, the long fiber padding layer is fixed, and the padding does not move even after being sewn into the fiber structure, making it possible to launder the sheet at home. Furthermore, because no adhesive or the like is used, a laminated padding sheet and its fiber structure that have a soft texture can be obtained.

[0011] Fig. 1 is a schematic perspective view of a laminated padded sheet according to one embodiment of the present invention. Fig. 2 is a schematic perspective view of a laminated padded sheet according to another embodiment of the present invention. Fig. 3 is a schematic explanatory view showing an apparatus for manufacturing a laminated padded sheet according to one embodiment of the present invention. Fig. 4 is a schematic side view of a long fiber yarn according to one embodiment of the present invention. Fig. 5 is a schematic explanatory view showing a method for manufacturing a long fiber yarn according to one embodiment of the present invention.

[0012] The laminated batting sheet of the present invention is a laminated batting sheet including a long-fiber batting layer and a fiber sheet layer. The long-fiber yarns constituting the long-fiber batting layer are composed of at least core yarns and filament yarns, and the two are integrated. The long-fiber yarns are also called continuous fiber yarns or filament yarns. The long-fiber batting layer is formed by aligning multiple long-fiber yarns and spreading them in parallel in the length direction to form a sheet. This results in a sheet of uniform thickness. On the other hand, by adjusting the number of long-fiber yarns to form a sheet with varying density, it is possible to create a sheet with different bulkiness in a single sheet. In addition, fiber sheet layers are laminated and integrated on both sides of the sheet-like long-fiber batting layer, serving as protective layers to prevent fraying of the long-fiber batting layer. The layers are then quilted together with quilting yarn in the thickness direction and across the length direction of the long-fiber yarns.

[0013] The mass per unit length of the laminated padding sheet (basis weight) is 30 to 700 g / m ２ is preferred, and 35 to 600 g / m ２ More preferably, 40 to 500 g / m ２ This allows for the production of fiber structures for padded clothing ranging from thin to thick, as well as for quilts and other items. When used for padded clothing, the fiber structure is 30 to 150 g / m ２ is preferable, and more preferably 40 to 130 g / m ２ and more preferably 50 to 110 g / m ２ The weight of the long fiber filling layer is 10 to 690 g / m ２ is preferable, and more preferably 15 to 590 g / m ２ and more preferably 20 to 490 g / m ２ This also makes it possible to obtain a fiber structure such as a padded garment having a thickness ranging from thin to thick.

[0014] The fiber sheet layer is preferably at least one layer selected from the group consisting of woven fabric, knitted fabric, net, mesh, and nonwoven fabric. These fiber sheet layers are suitable as protective layers to prevent fraying of the long fiber filling layer. Woven fabrics such as gauze fabric and cheesecloth fabric have a coarse weave and a basis weight of 5 to 50 g / m. ２For knitted items, the weight is preferably in the range of 5 to 50 g / m by using thin yarn and knitting with a coarse stitch. ２ The nonwoven fabric preferably has a basis weight of 5 to 50 g / m. ２ In the range of 5 to 20 g / m, a long fiber nonwoven fabric or a short fiber nonwoven fabric is preferred, and a long fiber nonwoven fabric is more preferred. A long fiber nonwoven fabric, for example, a spunbonded nonwoven fabric, is thin and lightweight, and therefore is preferred for use in a fiber sheet layer. In particular, a basis weight of 5 to 20 g / m ２ A polyester nonwoven fabric having a thickness of 0.05 to 0.25 mm is preferred. Staple fiber nonwoven fabrics can be made into carded webs and formed into thin, uniform nonwoven fabrics. It is also easy to blend fibers containing low-melting point components with high-melting point fibers. Here, staple fibers preferably have a length in the range of 10 to 100 mm, more preferably 20 to 80 mm, even more preferably 30 to 60 mm, and particularly preferably 40 to 50 mm.

[0015] The fibers constituting the nonwoven fabric are preferably synthetic fibers such as polyester, nylon, and polypropylene. The fiber sheet layer is preferably a fiber sheet layer containing polyester staple fibers and low-melting-point staple fibers, a thermal-bonded nonwoven fabric, or a spun-bonded nonwoven fabric. These nonwoven fabrics are thin and strong, and are suitable for protecting the long-fiber filling layer. Furthermore, when placed on both outer layers, they are easy to handle.

[0016] The quilting is preferably shaped so that each long-fiber batting is quilted to one of the quilting threads. Any shape that crosses the longitudinal direction of the long-fiber batting is acceptable, including arcs, curves, and diagonal lines. A shape including diagonal lines refers to a shape including diagonal lines that cross the longitudinal direction of the long-fiber batting, such as a zigzag shape. For example, the pitch between the peaks of the zigzag quilting is preferably 5 to 25 cm, more preferably 8 to 23 cm, and even more preferably 10 to 20 cm. The peaks refer to the bending points of the quilting, and each point that bends in the same direction as a peak is called a peak. Furthermore, the quilting spacing is preferably 2 to 10 cm, more preferably 3 to 9 cm, and even more preferably 4 to 8 cm. This allows for integrated lamination and fixes the movement of the long-fiber batting layer, making the resulting fiber structure suitable for home laundering.

[0017] In the case of zigzag quilting, it is preferable that the straight line connecting the peaks of one zigzag quilting pattern be used as a reference line, and the bending points of other quilting patterns are located on the reference line or on the side of the quilting pattern where the reference line was created. In other words, it is preferable that each long fiber batting is quilted to one of the quilting yarns. This makes it possible to eliminate long fiber yarns that are not fixed by quilting among the long fiber yarns that make up the long fiber batting, thereby improving the washing durability of the fiber structure.

[0018] The width of the laminated padding sheet is preferably 0.3 to 6 m, more preferably 0.5 to 5 m. This width allows it to be used in a wide range of products, from clothing to bedding.

[0019] The laminated padding sheet is preferably wound on a winding body, which allows it to be fed through an automatic cutting machine when sewing textile structures such as padded garments, making it suitable for mass production.

[0020] The method for producing a laminated batting sheet of the present invention includes the following steps: (1) a step of aligning a plurality of long fiber yarns, each of which is composed of at least a core yarn and an effect yarn and in which the core yarn and the effect yarn are integrated; (2) a step of aligning a plurality of long fiber yarns, each of which is composed of the core yarn and the effect yarn, and arranging them in parallel in the length direction to form a long fiber batting layer; (3) a step of laminating fiber sheet layers on both sides of the long fiber batting layer; (4) a step of quilting the layers with a quilting yarn in the thickness direction and transverse to the length direction of the long fiber yarns to integrate them; and (5) a step of winding the layer onto a winding body.

[0021] The long fiber yarn is preferably a bulky yarn, and is preferably composed of at least two types of core yarn and effect yarn, the core yarn being relatively short compared to the effect yarn, and the core yarn and the effect yarn being an integrated long fiber yarn. While it is optional to add fibers other than the core yarn and effect yarn, the total of the core yarn and effect yarn is preferably 70% by mass or more, more preferably 80% by mass or more, when the long fiber yarn is taken as 100% by mass. The core yarn and effect yarn are integrated. Here, "integrated" refers to a state in which the fibers are entangled or wound around each other. The core yarn is relatively short compared to the effect yarn. Bulkiness is achieved by providing a difference in length between the core yarn and the effect yarn. The weight ratio of the effect yarn to the core yarn, when the total of the effect yarn and the core yarn is used as the modulus, is preferably in the range of 51 to 99% by mass (wt%). It is more preferably in the range of 80 to 98 wt%, and particularly preferably in the range of 85 to 97 wt%. Within the above range, both component yarns are firmly fixed and the texture is good. It is preferable that both the core yarn and the filament yarn are continuous fibers (long fibers, filament fibers).

[0022] The mass per unit length of a single long fiber yarn is preferably 0.01 to 3 g / m, more preferably 0.02 to 1.5 g / m. 2 to 1,800, preferably 2 to 1,000, more preferably 5 to 500, and particularly preferably 10 to 250, of these long fiber yarns are bundled and aligned. The mass per unit length of a single bundle of aligned long fiber yarns is preferably 0.15 to 45 g / m, more preferably 0.3 to 25 g / m. This range facilitates handling when forming a laminated batting sheet. The long fiber yarn may be wound or stored in a carton container. The width of the laminated batting sheet is preferably 0.3 to 3 m, more preferably 0.5 to 2.5 m.

[0023] The fiber structure of the present invention is preferably used in the form of clothing, bedding, sleeping bags, or parts thereof. Specifically, it is preferably used in the form of jackets, shirts, pants, vests, coats, cold weather clothing, work clothes, neck warmers, or parts thereof. Clothing such as jackets, shirts, and pants is suitable for sports. It may also be used as an inner jacket.

[0024] It is preferable that at least a urethane-based crosslinking agent, an acrylic-based crosslinking agent, or an epoxy resin crosslinking agent is applied to the long fiber yarn as a crosslinking agent and fixed by curing. This improves bulkiness and washability. Furthermore, it is preferable to use, as a surface treatment agent, a resin smoothing agent that improves smoothness, such as a silicone-based resin, in combination with the crosslinking agent. In particular, it is preferable to use a silicone-based resin agent in combination with a urethane-based crosslinking agent. The crosslinking agent and / or smoothing agent are preferably applied in an amount of 0.1 to 10% by mass relative to the long fiber yarn.

[0025] The core yarn and filament yarns can be made of fibers such as polyester, nylon, and polypropylene, but polyethylene terephthalate (PET) hollow yarns are preferred. Polyethylene terephthalate hollow yarns are warm due to their insulating effect, and PET has stiffness and can maintain high bulkiness. A hollow ratio of approximately 10 to 40% is preferred.

[0026] The core yarn and the effect yarn are preferably integrated by at least one process selected from entanglement, air jet processing, winding processing, and processing in which the effect yarn is jetted onto the core yarn. The entanglement process is a process using an air entanglement machine that jets compressed air perpendicular to the running direction of the core yarn and the effect yarn. The air jet processing is a so-called taslan process, in which compressed air is forced into the core yarn and the effect yarn in the direction of travel. The winding process is a process in which the effect yarn is wound onto the core yarn to integrate them. The process in which the effect yarn is jetted onto the core yarn to entangle or rotate the effect yarn.

[0027] The single fiber fineness of the core yarn and the effect yarn is preferably 0.1 to 300 decitex, and the total fineness is preferably in the range of 10 to 600 decitex. More preferably, the single fiber fineness is 1.0 to 50 decitex, and the total fineness is 15 to 250 decitex. If the fineness is in the above range, the yarns are less likely to settling and have a good feel.

[0028] The filling structure of the present invention limits the movement of the long fiber yarns even after repeated washing, resulting in a stuffed product with little bias and high bulk. The filling structure of the present invention may also use other filling materials in addition to the long fiber yarns. It may also be used in combination with feathers, artificial feathers, or staple cotton.

[0029] The following description will be made with reference to the drawings. In each drawing, the same reference numerals indicate the same parts. FIG. 1 is a schematic perspective view of a laminated padding sheet 1 according to one embodiment of the present invention. This laminated padding sheet 1 has a long-fiber padding layer 2 formed by arranging a large number of long-fiber yarns in the longitudinal direction, and fiber sheet layers (surface sheet layers) 3a, 3b are laminated on both surfaces of the long-fiber padding layer 2 and sewn in the thickness direction with zigzag quilting threads 4a, 4b, 4c, 4d, etc. When the long-fiber padding 2 is used alone, the bulky long fibers tend to get caught on various objects, causing fraying and reducing handleability. However, when the fiber sheet layers (surface sheet layers) 3a, 3b are laminated and integrated on both surfaces of the long-fiber padding layer 2, handleability improves and the sheet can be easily applied to existing garment manufacturing processes.

[0030] FIG. 2 is a schematic perspective view of a laminated padding sheet 5 according to another embodiment of the present invention. This laminated padding sheet 5 has a padding layer with a varying mass across the width, comprising a thick padding layer (a portion with a high mass of padding) 6 and thin padding layer (a portion with a low mass of padding) 7a, 7b. This configuration allows the thick padding layer (a portion with a high mass of padding) 6 to be used in the body of a jacket, for example, and the thin padding layer (a portion with a low mass of padding) 7a, 7b to be used in the sleeves, for example. The padding layer mass can be varied in three stages and used in the front, back, and sleeves, respectively. The padding layer mass can also be varied in four stages and used in the front, back, sleeves, and head, respectively.

[0031] FIG. 3 is a schematic diagram illustrating a laminated batting sheet manufacturing apparatus 10 according to one embodiment of the present invention. In this laminated batting sheet manufacturing apparatus 10, long fiber yarns 2a, 2b, 2c, 2d, etc., drawn from yarn wound bodies 11a, 11b, 11c, 11d, etc., are passed through guide rolls 12 and aligned in a planar direction to form a sheet-like long fiber batting layer 2. Meanwhile, fiber sheets 3a, 3b drawn from rolls 13a, 13b are passed through guide rolls 14a, 14b, 15a, 15b to be laminated on both surfaces of the sheet-like long fiber batting layer 2. The sheets are then quilted in a zigzag pattern with sewing thread 17 using sewing machine needles 16 to form a laminated batting sheet 1. Reference numeral 18 denotes a sewing machine base. The laminated batting sheet 1 thus obtained is wound onto a roll 20. By winding the sheet onto a roll, it can be transported like ordinary fabric, making it easy to handle, and it also simplifies the process of removing the required amount of batting from the roll when using it.

[0032] 4 is a side view of a continuous fiber yarn (air-entangled yarn) 31 according to one embodiment of the present invention. In this continuous fiber yarn 31, constituent fibers of a core yarn 32 and an effect yarn 33 are entangled with each other, and the effect yarn 33 is opened to form partially looped fibers.

[0033] Figure 5 is a schematic diagram of a continuous fiber filling manufacturing apparatus according to one embodiment of the present invention. A core yarn 34a is drawn from a yarn winding body 34, and an effect yarn 35a is drawn from a yarn winding body 35. The yarns are passed through two feed rolls 36 and 37 and a yarn guide 38 before being supplied to an air entangling device 40. When compressed air is supplied to the air entangling device 40 from a compressed air line 41, the fibers in the yarn path 39 are opened and rotated, thereby entangling each other. Reference numeral 42 denotes a continuous fiber yarn (air entangled yarn). After undergoing a mixed fiber entanglement treatment using an entanglement nozzle with a core yarn supply speed of 10 to 200 m / min, an effect yarn supply speed of 20 to 10,000 m / min, a winding speed of 10 to 200 m / min, and an air pressure of 0.01 to 1.0 MPa, the yarn passes through a delivery roll 43 and is wound onto a yarn winding body 45. Reference numeral 44 denotes a winder roll. This method has the advantage of enabling high-speed yarn winding of 20 to 1,500 m / min, resulting in high productivity. Instead of winding the yarn onto the spool 45, the yarn may be stored in a can. It is preferable to apply a silicone resin to the resulting filament yarn (air-entangled yarn). As the silicone resin, a reactive silicone treatment agent having a hydrogen group (-OH) or a vinyl group (-CH=CH2) at the molecular end is preferably used. For example, soft silicones such as "TERON E 530" bulky silicone, "TERON E 731," and "TERON E 722" manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd. can be used. The amount of the silicone resin applied is preferably 0.1 to 10% by mass of the wadding on a dry basis. Next, in a heat treatment step, the silicone resin is cured by heat treatment at 140 to 190°C for 1 to 10 minutes.

[0034] The present invention will be described in more detail below with reference to examples. However, the present invention is not limited to the following examples. (Example 1) (1) A polyethylene terephthalate (PET) hollow filament yarn (35% hollowness), 40 decitex fineness, and 12 filaments was used as the long-fiber batting core yarn, and a PET hollow filament yarn (35% hollowness), 40 decitex fineness, and 12 filaments was used as the effect yarn. A long-fiber batting was produced by the method shown in Figure 5. Next, in the silicone resin application step, 15 of the long-fiber yarns were bundled and treated. The silicone resin used was an aqueous solution containing 10% by mass of "Teron E-530" (manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd.) and 0.5% by mass of "Marpoteron E-722" (manufactured by the same company) as a crosslinker. The amount applied was 3.0 wt% of the long-fiber yarn on a dry basis. Next, in the heat treatment step, the long-fiber yarn was heat-treated at 140 to 190°C for 1 to 13 minutes to thermally cure and fix the silicone resin. The mass of one bundle of 34 continuous fiber yarns obtained was 4.1 g / m. (2) Fiber Sheet A thermal bonded nonwoven fabric was used as the fiber sheet. This nonwoven fabric was a blend of 70% by weight of nylon staple fibers (fineness 1.7 decitex, fiber length 51 mm) and 30% by weight of polyester staple fibers (fineness 1.6 decitex, fiber length 51 mm), and had a basis weight of 16 g / m. ２ , and a thickness of 0.1 mm. (3) Production of Laminated Padded Sheet A laminated padded sheet was produced as shown in Figure 3. Nine bundles of long fiber yarns (4.1 g / m per yarn) were pulled out from each spool and arranged to a width of 150 cm. 150 cm wide thermal bonded nonwoven fabrics were placed on both sides and laminated on both surfaces of the long fiber sheet 12 on a guide roll 20. Next, the sheets were quilted with sewing thread 23 using a sewing machine needle 22 to form a laminated padded sheet 24, which was then wound up on a roll 25. The zigzag quilting had a peak pitch of 15 cm and a quilting interval of 5 cm. On the straight line connecting the peaks of one quilting, another quilting peak was present. The resulting laminated padded sheet was as shown in Figure 1, and had a basis weight of 58 g / m. ２The thickness was 12.0 mm. To reduce variations in thickness, an 8.5 cm x 21.5 cm polystyrene foam plate (weight: 4.9 g) was placed on the laminated padding sheet, and the height of the underside of the polystyrene foam plate was measured at two points, and the average value was taken as the thickness.

[0035] The laminated padding sheet obtained in this way was confirmed to be easy to handle, easily applicable to existing clothing manufacturing processes, and to have high bulk and good flatness. Furthermore, when this laminated padding sheet was used in the front and back of a vest and a wear test was conducted, it was confirmed that the padding did not shift even after long-term use, was home-washable, and had a soft texture.

[0036] (Example 2) Instead of the thermal bonded nonwoven fabric, a spunbonded nonwoven fabric (made of polyester, basis weight 12 g / m) was used as the fiber sheet. ２ The same procedure as in Example 1 was carried out except that a laminated padding sheet (0.1 mm thick) was used. The basis weight of the obtained laminated padding sheet was 50 g / m ２ The thickness was 12.3 mm. The laminated padding sheet obtained in this manner was confirmed to be easy to handle, easily applicable to existing clothing manufacturing processes, and to have high bulk and good flatness. This laminated padding sheet was used in the front and back of the vest, and a wear test was conducted. It was confirmed that the padding did not move even after long-term use, was home-washable, and had a soft texture.

[0037] (Example 3) As shown in Figure 2, a laminated padding sheet 5 was produced in which the mass of the padding layer varied in the width direction. Five bundles of 34 long fiber yarns (4.1 g / m per bundle) were arranged in the center 6, and two bundles of 17 long fiber yarns (2.1 g / m per bundle) were arranged in the left and right portions 7a and 7b. The remaining portions were produced in the same manner as in Example 1. The basis weight of the thick portion 6 of the padding layer (portion with a large amount of padding mass) was 58 g / m. ２ The thickness is 12.0 mm, and the basis weight of the thin parts (parts with less filling mass) 7a and 7b of the filling layer is 45 g / m ２The thickness was 6.0 mm. To reduce variation in thickness, an 8.5 cm x 21.5 cm polystyrene foam plate (weight: 4.9 g) was placed on the laminated padding sheet, and the height of the underside of the polystyrene foam plate was measured at two points, and the average value was used as the thickness. A jacket was sewn using the thicker portions of the padding layer (portions with a higher padding mass) of the resulting laminated padding sheet in the front and back body, and the thinner portions of the padding layer (portions with a lower padding mass) in the sleeves, and a wear test was conducted. It was confirmed that the padding did not shift even after long-term use, was home-washable, and had a soft texture.

[0038] The padding structure of the present invention is preferably used in jackets, shirts, pants, vests, coats, cold weather clothing, work clothes, neck warmers, futons, or parts thereof. Jackets, shirts, pants, and other clothing are suitable for sports. They may also be used as inner jackets.
