Description

[Technical field]

[0001] The present invention relates to a filling structure and a stuffed object using the same, and more particularly to a filling structure having high bulk and shape stability and a stuffed object using the same. [Background technology]

[0002] The feathers used to fill feather products such as down comforters and down jackets are generally from waterfowl. Waterfowl include geese, ducks, and eiders (wild ducks) that live on the coastlines of the Arctic Circle. There are two types of feathers: down, which is similar to chest hair, and feathers, both of which are used in feather products. Feathers are produced in Central Europe, such as Poland and Hungary, Northern Europe, including the Scandinavian Peninsula, and China. Feathers are bulky and warm, and occupy a position as a luxury material for feather products such as duvets and down jackets. However, natural feathers are dependent on waterfowl, and there is a limit to the supply, and the supply fluctuates due to natural conditions and harmful diseases (such as avian viruses). From the perspective of nature conservation, there is also a limit to capturing wild birds. Furthermore, natural feathers can cause a foul odor if not washed properly, so it is necessary to remove the filth that causes the odor in advance and to maintain a certain level of cleanliness and oxygen count, which indicate the degree to which the feathers have been washed. Another basic problem is that it is not easy to wash feather products such as feather duvets and feather jackets.

[0003] Therefore, there have been many proposals for batting. Patent Document 1 proposes shrinking polyester fibers by heat treatment to cause crimping and provide bulk and elasticity. Patent Document 2 proposes batting in which a core yarn is wrapped around and entangled with an effect yarn. The applicant of the present invention has proposed batting in which a core yarn and an effect yarn are entangled in Patent Documents 3 to 5. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] In the filling structure of the present invention, the long fiber filling and the nonwoven fabric are integrated, so that the long fiber filling and the nonwoven fabric are fixed to each other, restricting their free movement, and improving heat retention, bulkiness, and durability against washing, etc. The long fiber filling is composed of at least two types of long fibers A and B, the long fiber A being relatively shorter than the long fiber B, and the long fibers A and B being integrated, and the nonwoven fabric is composed of a fiber web in which hollow polyester staple fibers, crimped polyester staple fibers, and low-melting-point staple fibers are mixed, so that the heat retention and bulkiness are excellent, and the crimped fibers and the long fiber filling are moderately entangled, improving washing durability.

[0012] The mass ratio of the long fiber filling and the nonwoven fabric, when the filling structure is taken as 100% by mass, is preferably 10 to 90% by mass for the long fiber filling and 90 to 10% by mass for the nonwoven fabric, more preferably 20 to 80% by mass for the long fiber filling and 80 to 20% by mass for the nonwoven fabric, even more preferably 30 to 70% by mass for the long fiber filling and 70 to 30% by mass for the nonwoven fabric, and particularly preferably 40 to 60% by mass for the long fiber filling and 60 to 40% by mass for the nonwoven fabric.

[0013] The nonwoven fabric is preferably a sheet-like nonwoven fabric, and is preferably a chemically bonded nonwoven fabric to which a binder resin is sprayed from the surface of the fiber web. This allows for a sheet-like nonwoven fabric with good dimensional stability. In addition, the amount of binder inside is reduced, allowing for a soft texture. In order to maintain the internal shape, adhesive fibers, i.e., staple fibers with a lower melting point on the surface than hollow polyester staple fibers or crimped polyester staple fibers, preferably low-melting polyester staple fibers, are blended.

[0014] Of the fibers used in the nonwoven fabric, at least the hollow polyester staple fibers preferably have a silicone oil applied to their surfaces, which can improve the texture.

[0015] The mass per unit area of ​​the nonwoven fabric (basis weight) is 5 to 50 g / m 2This allows for a light-weight padding structure to be obtained. The weight per unit area of ​​the padding structure is preferably 10 to 40 g / m 2 is preferable, and more preferably 15 to 30 g / m 2 It is.

[0016] The nonwoven fabric preferably has an apparent thickness of 2 to 15 mm when left at rest. This allows it to be combined with long fiber filling to form a filling structure (wadding) of desired thickness. The apparent thickness is measured without applying any particular load.

[0017] The fineness of the fibers constituting the nonwoven fabric is preferably 0.5 to 5 decitex, and more preferably 1 to 3.3 decitex, which allows a filling structure with high heat retention to be obtained.

[0018] The nonwoven fabric is composed of a fiber web in which hollow polyester staple fibers, crimped polyester staple fibers, and low melting point polyester staple fibers are mixed. Hollow polyester staple fibers have high heat retention. The hollow ratio is preferably about 30%. By mixing this with crimped polyester staple fibers, especially visibly crimped polyester staple fibers, it is possible to achieve a bulky and soft texture, and durability is improved by entangling with the loop fibers of the long fiber filling. In addition, by mixing low melting point polyester staple fibers, it is possible to maintain high shape stability. The blending ratio of each fiber is preferably 30 to 50 mass% for hollow polyester staple fibers, 30 to 50 mass% for visibly crimped polyester staple fibers, and 10 to 30 mass% for low melting point polyester staple fibers, when the nonwoven fabric is taken as 100 mass%. The fiber length of each staple fiber is preferably about 38 to 60 mm. The nonwoven fabric is manufactured by blending hollow polyester staple fibers treated with silicone oil, forming a web, spraying a binder resin on the web, and drying the web. Such nonwoven fabric is commercially available from Kurashiki Textile Processing Co., Ltd.

[0019] The long fiber filling of the present invention is composed of at least two types of long fibers A and B. Although it is optional to add fibers other than long fibers A and B, the total amount of long fibers A and B is preferably 70% by mass or more, and more preferably 80% by mass or more, when the long fiber filling is 100% by mass. Long fibers A and B are integrated. Here, "integrated" refers to a state in which the fibers are entangled or wound around each other. Long fiber A is relatively short compared to long fiber B. Bulkiness can be achieved by providing a difference in length between long fibers A and B.

[0020] In the long fiber filling of the present invention, the long fiber A may contain conductive fibers. The long fiber A is relatively short compared to the long fiber B, and has an antistatic effect. The long fiber A preferably contains 10% by mass or more and 100% by mass or less of conductive fibers. Specifically, the long fiber A preferably contains 10% by mass or more and 100% by mass or less of conductive fibers. More preferably, the content is 15% by mass or more and 50% by mass or less. If the content is within the above range, the antistatic function can be exhibited. When the conductive fiber is 10% by mass or more and less than 100% by mass, the conductive fiber yarn and the normal yarn (for example, the polyester yarn used as the long fiber B described below) are aligned and integrated by a method such as intertwining or doubling. The conductive fiber includes metal fibers, carbon fibers, fibers kneaded with metal particles or carbon particles, and fibers using conductive polymers. For example, there are antistatic yarns manufactured by KB Seiren Co., Ltd. and antistatic yarns manufactured by Kuraray Co., Ltd. In addition, since the long fiber A is relatively short compared to the long fiber B, the amount of the conductive fiber yarn used can be reduced by including the conductive fiber yarn in the long fiber A, thereby reducing costs. On the other hand, when the long fiber B contains a conductive fiber thread, the bulkiness tends to decrease. The ratio of conductive fiber in the long fiber filling containing the long fiber A and the long fiber B is preferably about 0.5 to 5 mass %. Within this range, antistatic function can be exhibited. Furthermore, the obtained long fiber filling may be used in a bundle of about 5 to 50 pieces. In this case, it is not necessary to use conductive fiber in the long fiber A of all 5 to 50 pieces of the long fiber filling, and it is sufficient to use about 3 to 12 pieces of long fiber A containing conductive fiber, for example, in a bundle of 30 pieces, that is, about 5 to 40% of the number of pieces in the bundle. In this case, the ratio of conductive fiber in a bundle using multiple long fiber fillings is preferably about 0.05 to 0.9 mass %.

[0021] The long fibers B can be solid yarns (ordinary yarns) such as polyester, nylon, and polypropylene, but polyethylene terephthalate (PET) hollow yarns are preferable. Polyethylene terephthalate hollow yarns are warm due to their insulating effect, and PET has stiffness and can maintain high bulkiness. A hollow ratio of about 30% is preferable.

[0022] The mass per unit length of one long fiber filling is preferably 0.01 to 3 g / m, more preferably 0.02 to 1.5 g / m, for ease of handling when used for filling.

[0023] The long fibers B are preferably 1.1 to 100 times, more preferably 2 to 100 times, and even more preferably 4 to 60 times longer than the long fibers A. Within this range, the long fibers B become loop fibers to the extent that they are longer, and can be made bulky.

[0024] It is preferable that long fiber A and long fiber B are integrated by at least one process selected from entangling, air jet processing, wrapping, and a process of spraying long fiber B onto long fiber A. The entangling process is a process using an air entangling machine that sprays compressed air perpendicular to the running direction of long fiber A and long fiber B. The air jet process is a so-called Taslan process, in which compressed air is forced into long fiber A and long fiber B in the traveling direction. The wrapping process is a process in which long fiber B is wound around long fiber A to integrate them. The process of spraying long fiber B onto long fiber A is a process in which long fiber B is sprayed onto long fiber A to entangle them.

[0025] It is preferable that a smoothing agent is fixed to the long fiber filling. This is because productivity is improved. Examples of the smoothing agent include silicone resin and fluororesin. Taking silicone resin as an example, it is preferable to apply the silicone resin to the long fiber filling and heat fix it by curing. The preferred amount of silicone resin attached is in the range of 0.1 to 10 mass% based on the long fiber filling. Furthermore, acrylic resin, urethane resin, epoxy resin, etc. may be used in combination to adjust hardness.

[0026] The single fiber fineness of the long fibers A and B is preferably in the range of 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 in the range of 1.0 to 50 decitex and the total fineness is in the range of 20 to 250 decitex. If the fineness is in the above range, the fibers are less likely to become worn out and have a good texture.

[0027] Next, the integration of the nonwoven fabric and the long fiber filling will be described. Examples of the means for integrating the two are as follows. (1) Long fiber batting is arranged in one direction on top of a nonwoven fabric and fixed with sewing thread in a direction perpendicular to the length of the long fiber batting. (2) A large number of slits are formed in multiple rows in the nonwoven fabric, and long fiber batting is passed through the slits so that the long fiber batting is exposed alternately on the front and back surfaces of the nonwoven fabric. The above-mentioned (2) method does not use sewing thread, so that the texture is good, and the long fiber filling and the nonwoven fabric are fixed to each other, restricting their free movement and improving heat retention, bulkiness, and durability against washing, etc. It is preferable to arrange multiple long fiber fillings together.

[0028] The padding structure of the present invention can be placed at a desired position in a garment. For example, it can be placed as a part in parts of a garment such as a collar, a front body, a back body, or a waist lining, or in parts such as shoulders, elbows, knees, buttocks, and head, and sewn together with other parts to create a garment, thereby warming only the parts that are desired to be warmed. In addition, by placing the padding structure as a part, a garment can be obtained that has both the functions of ease of movement and heat retention, which is effective even in cases involving vigorous movement. Furthermore, a function of enhancing protection of parts of the body can be added. Examples of uses include work, sports, and casual wear. Types of clothing include blousons, jackets, coats, pants, and overalls.

[0029] As an example of the use of the padding material, for example, by arranging the padding structure in the collar of the work clothes, it fits softly around the neck, contributing to heat retention and a good texture, and it becomes possible to work comfortably even when working outdoors in cold regions. In addition, by arranging the padding structure in the back of the work clothes, it becomes possible to work comfortably without hurting the back even when working while lying on one's back, in addition to heat retention. In addition, by arranging the padding structure in the shoulder of the work clothes, it becomes possible to prevent shoulder pain even when carrying or carrying a heavy load on the shoulder, in addition to heat retention. In addition, by arranging the padding structure in the elbow or knee of the work clothes, it becomes possible to prevent elbow or knee pain even when the body is in a position where the elbow or knee is pressed against a hard ground such as asphalt, in addition to heat retention. In addition, by arranging the padding structure in the buttocks, it is possible to add a function of not hurting the buttocks or causing discomfort even when sitting anywhere outdoors, in addition to heat retention. In addition, by arranging the padding structure in the hood of the work clothes, it becomes possible to protect from falling objects in addition to heat retention.

[0030] The following description will be given with reference to the drawings. In the following drawings, the same reference numerals indicate the same objects. Fig. 1 is a schematic perspective view of a filling structure according to one embodiment of the present invention. This filling structure is integrated with a nonwoven fabric 22 through which a long fiber filling 23 is inserted and passed through a slit hole 24.

[0031] Figures 2A-D are schematic explanatory diagrams showing the process of integrating a nonwoven fabric and long fiber filling according to one embodiment of the present invention, where Figure 2A is a schematic oblique view of a nonwoven fabric 22 with a slit hole 24 formed therein, Figure 2B is a schematic oblique view of a long fiber filling 23 passed through a slit hole 24 in the nonwoven fabric 22, Figure 2C is a schematic cross-sectional view of Figure 2B, and Figure 2D is a schematic cross-sectional view of the nonwoven fabric expanded. First, as shown in FIG. 2A, the nonwoven fabric 22 is folded to form a plurality of rows of slit holes 24 with a space therebetween. Next, as shown in FIG. 2B, the long fiber filling 23 is passed through the slit holes 24 of the nonwoven fabric 22. FIG. 2C is a schematic cross-sectional view of FIG. 2B. Next, the nonwoven fabric 22 is expanded as shown in FIG. 2D. This results in a filling structure 21. The filling structure may be formed by gathering a plurality of long fiber fillings on a nonwoven fabric sheet and arranging them in a large number of rows in one direction, and may be fixed, for example, by sewing thread. The long fiber filling 19 in the filling structure 21 may be arranged with a space therebetween or may be arranged densely. When the core threads are arranged with a space of preferably 3 to 9 cm, more preferably about 4 to 8 cm, the filling contains a lot of air and becomes bulky. In addition, the long fiber fillings are less likely to become entangled with each other even after washing, and the bulkiness can be maintained at a high level. Typically, long fiber batting is handled as a "bundle" of 10 to 50 threads, in which case the multiple core threads in the bundle are spaced apart from each other approximately at their centers as described above.

[0032] Fig. 3 is a schematic perspective view of the padding structure 21 of the embodiment shown in Fig. 2D. In this padding structure 21, a large number of slit holes 24 are opened in multiple rows in a nonwoven fabric 22, and long-fiber padding 23 is passed through the slit holes 24, and the long-fiber padding 23 is exposed alternately on the front and back surfaces of the nonwoven fabric 22. This padding structure 21 has a good texture because it does not use sewing thread, and the long-fiber padding 23 and the nonwoven fabric 22 are fixed to each other, restricting their free movement and improving heat retention, bulkiness, and durability against washing, etc.

[0033] Fig. 4 is a side view of a long fiber filling according to one embodiment of the present invention. In this long fiber filling 1, the constituent fibers of the core yarn 2 (long fiber A) and the filament yarn 3 (long fiber B) are entangled with each other, and the filament yarn 3 (long fiber B) is opened to form a partially looped fiber. This long fiber filling is also called air-entangled yarn.

[0034] FIG. 5 is a schematic explanatory diagram showing a method for manufacturing a long fiber filling. A core yarn 4a (long fiber A) and a core yarn 15a (antistatic yarn of long fiber A) are drawn from a wound yarn body 4, and a filament yarn 5a (long fiber B) is drawn from a wound yarn body 5, and are passed through two feed rollers 6 and 7 and a yarn guide 8 and supplied to an air interlacing device 10. When compressed air 11 is supplied to the air interlacing device 10, the fibers in the yarn path 9 are opened and rotated, so that they are interlaced with each other. 12 is a long fiber filling. The core yarn is supplied at a speed of 10 to 200 m / min, the filament yarn is supplied at a speed of 20 to 10,000 m / min, the winding speed is 10 to 200 m / min, and the mixed fiber interlacing process is performed by an interlacing nozzle with an air pressure of 0.01 to 1.0 MPa, after which the yarn passes through a delivery roller 13 and a winder roller 14 and is wound around a wound yarn body 16. This method has the advantage that the yarn winding speed can be increased to 20 to 1,500 m / min, resulting in high productivity.

[0035] The obtained long fiber filling is coated with silicone resin. Silicone resin has a molecular end with a hydrogen group (-OH) or a vinyl group (-CH=CH 2 It is preferable to use a reactive silicone treatment agent having the above properties. For example, bulky silicone under the trade names "TERON E 530" and soft silicones such as "TERON E 731" and "TERON E 722" manufactured by Matsumoto Yushi Seiyaku Co., Ltd. can be used. The amount of the agent applied is preferably 0.1 to 10 mass% based on the dry weight of the padding structure. Next, in the heat treatment step, the silicone resin is cured by heat treatment at 140 to 190°C for 1 to 10 minutes. EXAMPLES

[0036] The present invention will be specifically described below using examples, but the present invention is not limited to the following examples.

[0037] Example 1 (1) Creating nonwoven fabric The following silicone oil-treated fibers were used: Polyethylene terephthalate (PET) hollow fiber (fineness 3.3 decitex, fiber length 51 mm, silicone oil coating) 40% by weight, - 40% by weight of visibly crimped PET fiber (fineness 3.3 decitex, fiber length 51 mm), Low melting point PET fiber (fineness 3.3 decitex, fiber length 51 mm) 20% by weight The above fibers were mixed together to make a web, which was then spray-coated with an acrylic emulsion binder and dried to produce a chemically bonded nonwoven fabric. The mass per unit area (basis weight) was 30 g / m. 2 , and the thickness was about 6 mm. (2) Creating long fiber batting The core yarn was made of conductive fiber KB Seiren antistatic yarn with a fineness of 22 decitex and 3 filaments, and PET filament yarn with a fineness of 41 decitex and 18 filaments, and the filament yarn was made of PET hollow filament yarn (hollow rate 35%) with a fineness of 39 decitex and 12 filaments, to produce long fiber batting. The conductive fiber in the core yarn was about 40% by mass. The proportion of conductive fiber in the entire long fiber batting was about 1.6% by mass. Next, in the silicone resin application process, the long fiber filling was treated in a bundle of 15 pieces. As the silicone resin, an aqueous solution containing 10% by mass of "Teron E-530" (trade name, manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd.) and 0.5% by mass of "Marpoteron E-722" (trade name, manufactured by the same company) was used, and the amount applied was 3.0 wt% of the long fiber filling in terms of dry weight. Next, in the heat treatment process, the silicone resin was heat treated at 140 to 190°C for 1 to 13 minutes to thermally cure and fix the silicone resin. The mass of the resulting bundle of 15 long fiber fillings was 1.8 g / m. (3) Preparation of filling structure On the surface of the chemically bonded nonwoven fabric obtained above, 15 bundles of long fiber batting were arranged as shown in Figure 1. The number of bundles arranged was 15 / 5cm, and the interval between the bundles of long fiber batting was 5cm. The nonwoven fabric and the long fiber batting were then fixed by sewing. The interval between the sewing threads was 10cm. (4) Creation of stuffed objects The padding structure has a mass (basis weight) of 250 g / m 2The mixture was stuffed into the outer and inner linings of a woven fabric (100% polyester) and sewn into a jumper. The resulting jumper had good heat retention, bulkiness and shape stability, with no unevenness in the padding even after 10 washes according to the JIS L0217 103 method. It also dried easily even when wet with sweat, rain or water, and was easy to dry after washing.

[0038] Example 2 The nonwoven fabric of Example 1 and the long fiber filling were used to create the filling structure shown in Figures 2A-D. The number of fibers was 5 / 5 cm, and the slits were spaced 4 cm apart. The mass (weight per unit area) of the resulting filling structure was 72 g / m 2 The apparent thickness when left at rest was 30 mm. Otherwise, a jumper was sewn in the same manner as in Example 1. The obtained jumper had no unevenness of the padding even after 10 washes according to the JIS L0217 103 method, and had good heat retention, bulkiness, and shape stability. In addition, it was easy to dry even when wet with sweat, rain, water, etc., and was easy to dry after washing. [Industrial Applicability]
