  However, processing of cotton (so-called short fiber stuffed cotton) as disclosed in Patent Document 1 has a drawback that the shape tends to collapse.

  In order to solve the above-described problems, the present invention provides a fiber product filled with a stuffing that has high heat storage property and low cost, and a manufacturing method thereof.

  The fiber product of the present invention is a fiber product in which a long fiber in which a flower yarn is integrated with a core yarn is filled in a cloth, and the long fiber has a heat storage material using latent heat accompanying a phase change between melting and solidification. Is directly attached.

  In the method for producing a textile product of the present invention, a long fiber in which a flower yarn is integrated with a core yarn is brought into contact with a liquid containing a heat storage material having a latent heat accompanying a phase change between melting and solidification, dried and heat-set, and then It is characterized by filling in the fabric.

  The fiber product of the present invention is hard to move because the stuffed cotton is a long fiber, is bulky, and further has a heat storage property due to the direct attachment of a heat storage material using latent heat associated with the phase change between melting and solidification. High fiber products. For example, in the case of a futon, the warmth will remain longer if it is dried in the sunlight, and in the case of a jacket coat, the warmth will be reduced when moving from a warm place to a cold place, or vice versa. The difference can be buffered. Moreover, even if the method of this invention carries out the process which adheres a thermal storage substance directly to a long fiber, the integrity of a fiber, bulkiness, etc. do not change, but can take advantage of the long fiber stuffed cotton as it is.

  The heat storage material used in the present invention is preferably a paraffin wax having a melting point of 25 ° C. or more and 40 ° C. or less. The paraffin wax may be encapsulated. The paraffin wax may be attached to the fiber using a binder as long as the flexibility does not cause a problem in actual use. It is preferable that 1 to 20% by weight of the heat storage material is attached to the long fiber stuffed cotton. If it is the said range, heat storage can be utilized effectively. In addition, the paraffin wax can use what is marketed as a humidity control agent etc. which used the phase change substance (PCM).

  This heat storage material is dispersed in a solution such as water, and contacted by immersing long fiber stuffed cotton in the solution to dry and heat fix. Examples of the contact means include a padding method, a spray method, a roll coater method, and a slit coater method. The long fiber is brought into contact with the aqueous dispersion of the heat storage material, dried and heat-set, and then filled into the fabric. Even if the heat storage material is directly adhered to the long fiber stuffed cotton, if the both ends are fixed, the integrity and bulkiness of the fiber are not changed, and the advantages of the long fiber stuffed cotton can be utilized as they are. On the other hand, a short fiber stuffed cotton such as a normal card web tends to fall apart when immersed in or brought into contact with an aqueous solution, and the predetermined shape tends to collapse. Therefore, this point is also an advantage of using long fiber stuffed cotton.

  The long-fiber stuffed cotton used in the present invention is obtained by integrating flower yarns with a core yarn, and the flower yarns are opened to form loop-like fibers. Thereby, a bulky filling is obtained. In the present invention, “integrating the flower yarn with the core yarn” means that the constituent single fibers of the flower yarn and the core yarn are entangled with each other, and the constituent single fibers are not necessarily fused and fixed to each other. Of course, it may be fused and fixed. In addition, “the flower yarn is opened to form a loop-like fiber” means that the fiber may be opened at the same time during the air entanglement as in air entanglement, or may be opened by an independent fiber opening process. Means good. The integration of the flower yarn and the core yarn can be realized by twisting the flower yarn and the core yarn together or by tangling the flower yarn and the core yarn. The loop-shaped fiber may be composed of multifilament fibers that are long fibers, opened, and the loop-shaped fibers may be fused together. When the loop-shaped fibers are fused, the bulkiness and the washing resistance can be improved. That is, by fixing the opened loop-like fibers together, the number of fixing points increases, and it becomes difficult to sag. It may be entangled in addition to fusion. The entanglement can be realized by using the air nozzle to entangle the single fibers constituting the long fibers. In addition, a large number of long-fiber stuffed cottons are aligned in at least one direction, and both ends are sewn together with the side fabric and integrated with the side fabric. Since the stuffed cotton obtained by air entanglement is particularly apt to collapse, it is effective to use it in a long fiber state when attaching the paraffin wax of the present invention.

  The long fiber stuffed cotton is preferably formed into a long fiber stuffed cotton sheet by sewing both ends integrally with a ribbon-like narrow cloth. If it is a sheet | seat state, it is convenient to fill in a side ground, and the handleability at the time of sewing with a side ground will become favorable. The long fiber stuffed cotton may be sewn together with the side cloth at a portion other than both ends and integrated. For example, in the case of a futon, one or a plurality of quilts (sewing) may be put in the central portion of the main surface to integrate the long fiber stuffed cotton and the side fabric. This further improves the washing resistance.

  When the flower yarn and / or the core yarn includes a fusion fiber, the fusion fiber of the flower yarn and the core yarn is preferably a composite fiber composed of two or more polymers having different melting points. The composite fiber is preferably a fiber having a core-sheath structure in which the high melting point polymer is the core and the low melting point polymer is the sheath. This is for fusing the low melting point polymer. Examples of such a core-sheath composite fiber include “Belcouple” manufactured by KB Seiren, “Melset” manufactured by Unitika, and “EZBON” manufactured by Unjin Chemical. These composite fibers have a core made of polyethylene terephthalate (PET) and a sheath made of a low-melting polyester copolymer. It is preferable that the fused fibers of the flower yarn and the core yarn are polyester multifilament fused fibers. This is because polyester is difficult to sag. Moreover, it is preferable that the fusion | melting temperature of a fusion fiber is 160-200 degreeC. If it is this range, it will be easy to process.

  The flower yarn and / or the core yarn may further contain non-fusion fibers. As the non-fusion fiber, synthetic fibers such as polyester, nylon, and polypropylene are preferable. The ratio of the fused fiber and the non-fused fiber of the core yarn is 10 to 100% by weight of the fused fiber and 0 to 90% by weight of the non-fused fiber when the core yarn is 100% by weight. preferable.

  The average length of the loop of the loop-like fiber is preferably in the range of 1 to 200 mm, more preferably in the range of 5 to 50 mm, and still more preferably in the range of 10 to 40 mm. When the average length of the loops of the loop-like fibers is within the above range, the texture, bulkiness and bulk durability can be further improved.

  The single fiber fineness of the loop-like fiber (flower yarn) is preferably in the range of 0.1 to 300 dtex, and the total fineness is 10 to 600 dtex (dtex indicates deci tex). More preferably, the single fiber fineness is in the range of 1.0 to 50 dtex and the total fineness is in the range of 20 to 250 dtex, and particularly preferably, the single fiber fineness is in the range of 2.0 to 25 dtex and the total fineness is in the range of 30 to 100 dtex. If the fineness is within the above range, it is difficult to sag and the texture is good.

  The core yarn may include a composite fiber composed of two or more polymers having different melting points. Examples of the composite fiber composed of two or more polymers having different melting points include conjugate fibers in which polymers having different melting points are combined in a core-sheath shape, etc., specifically, the high melting point polymer is a polypropylene polymer, Examples thereof include a core-sheath fiber in which the low-melting polymer is a polyethylene polymer or a low-melting polypropylene polymer. A composite fiber composed of two or more polymers having different melting points may constitute a core yarn alone or in combination with other core yarns. From the viewpoint of more reliably integrating the loop-like fibers, it is preferable to use the core-sheath fiber in combination with the low-melting point heat-bonding fiber yarn.

  The difference in melting point between at least two types of core yarns having different melting points or two or more polymers having different melting points is preferably 10 to 200 ° C.

  Further, when air entangled yarn is used as the long fiber stuffed cotton, the flower yarn and the core yarn may be non-fused fibers. As the non-fusion fiber, synthetic fibers such as polyester, nylon, and polypropylene are preferable.

  The weight ratio of the loop-like fiber (flower yarn) to the core yarn is such that the ratio of the loop-like fiber (flower yarn) is 51 to 99% by mass (wt%). ) Is preferred. More preferably, it is the range of 80-98 wt%, Most preferably, it is the range of 85-97 wt%. If it is the said range, the fixed integration by a core thread will become firm, and a texture will also become favorable.

  It is preferable that a silicone treating agent is further heat-set in the stuffed cotton of the present invention. The preferable adhesion amount of the silicone treating agent is in the range of 0.1 to 10 wt% with respect to the total amount of the loop-like fiber (flower yarn) and the core yarn. Further, an acrylic resin, a urethane resin or the like may be fixed for adjusting the hardness.

  The stuffed cotton of the present invention is a long fiber. Basically, a length of tens of centimeters to hundreds of thousands of meters or more is also possible. When integrating with the side ground, it may be folded to the length of one side of the side ground or may be cut to a predetermined length. The direction in which the long fiber stuffed cotton is aligned is preferably in the direction perpendicular to the height direction of the human body. For example, in the case of a comforter, the width direction (horizontal direction), and in the case of a pillow, the length direction (vertical direction). The weight per unit length of the long fiber stuffed cotton is preferably in the range of 0.01 to 3 g / m, and more preferably in the range of 0.05 to 1.5 g / m. If it is the said range, manufacture is possible and handling property is also favorable.

  This will be described below with reference to the drawings. In the drawings, the same reference numerals denote the same parts. First, a comforter according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of the comforter. The comforter 1 has a side 2, sewing lines 4 and 5 formed on the two long sides of the side, and the length direction of the main surface (side) of the comforter 1. The sewing (quilt) line 6 is formed substantially at the center along the sewing line 6 and the sewing (quilt) lines 7a to 7c perpendicular to the sewing line 6. FIG. 2 is a cross-sectional view taken along the line I-I of FIG. 1 and shows a state in which the long fiber stuffed cotton 8 is fixed to the side grounds 2a and 2b with sewing lines 4, 5, and 6. 1 to 2, the sewing (quilt) lines 6, 7a to 7c are not always necessary, and may be omitted.

This pillow 3 has shown the state by which the long fiber filling cotton 8 is being fixed to the side grounds 2a and 2b with the sewing lines 4 and 5. FIG. This is an example where there is no quilt line in the center.

  FIG. 4 is an explanatory view showing fixing of both ends of the long fiber stuffed cotton in one embodiment of the present invention. Both ends of the long fiber stuffed cotton 8 are previously fixed to the ribbon-like narrow cloths 10a and 10b by sewing and formed into a long fiber stuffed cotton sheet 9. In this way, the long fiber stuffed cotton 8 can be handled as a single unit. In the case of a futon, in order to fill the side fabric in the state shown in FIG. 4, it is sewn in advance, leaving one of the short sides of the side fabric, turned over, and both ends of the side fabric and the ribbon of the long fiber-padded cotton sheet 9 The narrow fabrics 10a and 10b are sewn, and then the side ground is turned over, and one short side that has been opened is sewn. As another method, in the case of a futon, the side fabric which has been sewn in advance except for one of the short sides is filled with the long fiber-padded cotton sheet 9 of FIG. Sewing a thin narrow cloth and fixing it, then sew one short side that has been opened to make a futon. As another method, it is also possible to align a large number of long fiber-padded cotton 8, align both ends of the long-fiber-padded cotton directly with the ends of the side fabric, and fix them by sewing.

  In the example of FIGS. 1 to 4, the long fiber stuffed cotton 8 may be cut into a predetermined length and aligned, or a loop of a predetermined length such as a skein may be folded and folded at both ends. Good. In the sewn duvet 1 or pillow 3, both ends of the long fiber stuffed cotton are fixed to the side ground in the side fabric, and the length of the core yarn constituting the long fiber stuffed cotton varies between the two fixed portions. In addition, since the flower yarn and the core yarn are integrated, even if washing is repeated, the movement of the long-fiber stuffed cotton is limited, and the stuffed product is less bulky and bulky.

  FIG. 5 is an explanatory view showing a manufacturing process of the long fiber stuffed cotton of an example of the present invention. As shown in FIG. 5, the flower yarn 31 and the core yarn 32 are supplied to the waist gauge 33 and twisted in the twisting step 34.

As shown in FIG. 6, the flower yarn 11 is supplied to the waist gauge 13 by rotating or swinging the yarn, and one kind of flower yarn or at least two kinds of core yarns 12 a and 12 b sandwich at least a part of the flower yarn 11. As shown in FIG. Here, the waist gauge is a funnel-shaped instrument, which is an instrument that is capable of temporarily storing the thread, with the upper part being largely open, allowing the thread to be dropped therein, and the lower outlet being narrowed. Next, the flower yarn 11 and the core yarns 12 a and 12 b are twisted together to form the loop yarn 14. The loop yarn 14 is formed by actual twisting by the twisting machine 20. That is, the bobbin 17 is rotated via the motor 15 and the belt 16, and a traveler 19 is incorporated in the ring 18 around this, and by rotating behind the rotation of the bobbin 17, the loop yarn 14 passing through the traveler 19 is Real twist is applied. A preferable number of twists is 150 to 350 times / m. An enlarged view of the obtained loop yarn 14 is shown in FIG. The flower yarn 11 forms a loop, and the core yarns 12a and 12b are twisted together to collect the whole.

  The obtained loop yarn 14 is subjected to a fiber opening process in a kneading and fiber opening step 35 shown in FIG. In this step, two pieces of rubber, woven fabric, non-woven fabric, resin sheet, and the like are rubbed together so that the loop yarn put in between is crushed and opened like a loop-like fiber 23 shown in FIG. By performing such a fiber-opening treatment, a preferable bulkiness, for example, a bulkiness of 40 mm or more can be obtained. Further, by selecting the hollow or high-strength polyester fiber as the flower yarn and combining the fiber-opening treatment, or adding a polyester monofilament fiber of 30 dtex or less to the multifilament fiber and combining the fiber-opening treatment, It becomes possible to express sex.

The composite yarn after passing can be obtained by winding it with a bobbin with a ring twisting mechanism. Then, the loop yarn (air entangled yarn) obtained above is unwound from the bobbin and, if necessary, subjected to a fiber opening process in a kneading and fiber opening step shown in FIG. In the kneading / opening step, two pieces of rubber, woven fabric, non-woven fabric, resin sheet or the like are rubbed together, and the loop yarn put in between is rubbed and opened. Next, in the silicone resin spraying step, the silicone resin is sprayed. As the silicone resin, it is preferable to use a reactive silicone treating agent having a molecular end having a hydrogen group (—OH), a vinyl group (—CH═CH ₂ ) or the like. For example, soft silicon such as “TERON E 530” bulky silicon, “TERON E 731”, “TERON E 722” manufactured by Matsumoto Yushi Seiyaku Co., Ltd. can be used. It is preferable that the spraying amount is sprayed in a dry weight of 0.1 to 10 wt% with respect to the filling cotton. Next, in the heat treatment step, heat treatment is performed at 140 to 190 ° C. for 1 to 10 minutes to cure the silicone resin.
