Description

The present invention relates to a quilting fabric filled with long fiber batting.

Stuffed articles filled with long-fiber batting have been known for some time. In Patent Documents 1 to 4, the present applicant uses a core yarn made of long fibers and an interlaced yarn composed of a flower yarn made of long fibers longer than the core yarn, and the flower yarn is opened to form a loop-shaped fiber. A forming long-fiber batting is proposed. Patent Documents 2 to 4 also propose quilting fabrics such as futons to have stitches in the direction perpendicular to the length direction of the long fiber filling. This stops the movement of the batting and prevents bias.

However, in the quilting fabric of the prior art, stitches are inserted in a direction orthogonal to the length direction of the long-fiber batting, so the stitch line is long and the apparent bulkiness of the quilting cloth is low. I had a problem with moving around a lot.

In order to solve the above problems, the present invention provides a quilting cloth which can suppress the movement of batting even if the stitches are shortened and which has improved apparent bulkiness.

The quilting cloth of the present invention is a quilting cloth filled with fiber bundles in which a plurality of long fiber fillings are bundled together. Stitches are discontinuously inserted in the same direction as the length direction of the bundle so as to pass through any part of the fiber bundle, and both ends of the fiber bundle are edged with both-end stitches from above the side fabric. It is characterized by being sewn from the beginning to the end .

The present invention shortens the stitches by discontinuously inserting the stitches from the surface of the side fabric in the same direction as the length of the fiber bundle and passing through any part of the fiber bundle. It is possible to suppress the movement of the batting even if In addition, the side fabric portion between stitches (the side fabric portion without stitches) is flat, and the apparent bulkiness can be improved.

FIG. 6 is a side view of one long-fiber batting. FIG. 7 is a schematic illustration of the method of manufacturing the long-fiber batting.

The quilting cloth of the present invention is filled with fiber bundles in which a plurality of long fiber fillings are bundled together. This makes it possible to increase the bulkiness and increase the heat retention effect. The fiber bundles are unidirectionally arranged in the side fabric. The unidirectional alignment results in a quilting fabric of substantially uniform thickness. In this quilting cloth, stitches are discontinuously applied from the surface of the side fabric in the same direction as the length of the fiber bundle and so as to pass through any part of the fiber bundle. As a result, even if the stitches are shortened, the movement of the batting can be suppressed. In addition, the side fabric portion between stitches (the side fabric portion without stitches) is flat, and the apparent bulkiness can be improved. In the above description, the stitch refers to the portion where the side fabric and the batting are fixed by the sewing line.

The quilting cloth of the present invention is a cloth-like material in which a fiber bundle is sandwiched between two or more cloths and stitched together. The quilting cloth of the present invention includes not only thin cloth-like cloth but also thick cloth such as those used for futons and cushions. In the present invention, the same direction does not require strict identity, but may be approximately the same. In addition, in the present invention, the term "bundle of fibers bundled together" is not limited to those in which a plurality of long fiber battings are bundled together with a separate member, or bundled together by sewing yarn or knitting yarn, but simply without separate members. It also includes fiber bundles that are collected by being intertwined and can be handled as a single bundle.

For quilting fabrics, the stitch length is preferably longer than the length between stitches (partial length without stitches). As a result, movement of the batting can be further suppressed.

The filling amount of the fiber bundle (filling) is preferably 30-250 g/m ² . More preferably 40 to 200 g/m ² . If the filling amount of the fiber bundle (filling) is within the above range, the heat retention will be good.

The weight per unit length of one long fiber filling is in the range of 0.01 to 1 g/m, and the fiber bundle contains about 5 to 200 long fiber fillings, considering the light weight of the garment. In that case, it is preferable that the number of wires is 5 to 50. It is convenient as a quilting cloth for clothes that it is the said range. A particularly preferred number of long fiber fillings in one fiber bundle is 10 to 40.

The long-fiber batting is preferably an interlaced yarn composed of a core yarn and a filament yarn longer than the core yarn, and the filament yarn is preferably opened to form a loop-like fiber. As a result, it is possible to obtain a filling that is hard to sag and has high resistance to washing. The long-fiber batting is preferably an interlaced yarn composed of a core yarn and a filament yarn longer than the core yarn. The proportion is preferably in the range of 60-98% by weight, more preferably in the range of 70-98% by weight, particularly preferably in the range of 85-98% by weight. Within this range, the length of the filament becomes a loop fiber corresponding to the length of the filament, resulting in a high bulk.

The filament threads of the interlacing threads are preferably 5 to 50 times longer than the core threads. Within this range, the length of the filament becomes a loop fiber corresponding to the length of the filament, resulting in a high bulk. Especially for quilting cloth, the filament yarn of the interlacing yarn is preferably 15 to 40 times longer than the core yarn. The magnification can be adjusted by adjusting the supply speed of the core thread and the filament thread.

The average loop length of the looped fibers is preferably in the range of 1 to 200 mm, more preferably in the range of 5 to 50 mm, even more preferably in the range of 10 to 40 mm. If the average loop length of the loop-shaped fibers is within the above range, the texture, bulkiness and bulk durability can be further enhanced.

The single fiber fineness of the loop-like fibers (flower threads) of the long fiber filling is preferably in the range of 0.1 to 300 dtex, and the total fineness is preferably in the range of 10 to 600 dtex (dtex indicates deci tex). More preferably, the single fiber fineness is 1.0 to 50 dtex and the total fineness is 20 to 250 dtex, and particularly preferably the single fiber fineness is 2.0 to 25 dtex and the total fineness is 30 to 100 dtex. When the fineness is within the above range, the fabric is less likely to be flattened and has a good texture.

The long-fiber batting can be produced by an air interlacing machine that jets compressed air in a direction perpendicular to the running direction of the core yarn and the filament yarn. Efficient production can be achieved by this production method. The long fiber filling may be untwisted, and the winding speed of the yarn in the untwisted case can be 50 to 1500 m/min.

As the filament yarn and/or the core yarn, ordinary synthetic fibers (non-fusion fibers) can be used. Fibers such as polyester, nylon, and polypropylene are preferable as the material of the long fiber filling.

It is preferable that the long-fiber batting of the present invention is further heat-set with a silicone treatment agent. The preferred amount of the silicone treatment agent to be adhered is in the range of 0.1 to 10 wt % with respect to the total amount of the loop-like fibers (flower threads) and the core threads. Further, acrylic resin, urethane resin, or the like may be fixed to adjust hardness.

The long fiber filling used in the present invention can basically have a length of several tens of centimeters to several hundred thousand meters or longer. When integrated with the side fabric, it may be folded to the length of one side of the side fabric, or may be cut to the length of the futon. It is preferable that the long-fiber fillings are aligned in the height direction of the human body (body length direction). For example, the vertical direction of the jacket. The weight per unit length of one long fiber filling is preferably in the range of 0.01 to 1 g/m, more preferably in the range of 0.02 to 0.5 g/m. Within the above range, production is possible and handling is good.

The long-fiber batting of the present invention may be coated with a silicone resin. As the silicone resin, it is preferable to use a reactive silicone treatment agent having a hydrogen group (--OH), a vinyl group (--CH=CH ₂ ) or the like at the molecular end. For example, soft silicon such as "TERON E 530" bulky silicon, "TERON E 731" and "TERON E 722" manufactured by Matsumoto Yushi Seiyaku Co., Ltd. can be used. The spraying amount is preferably 0.1 to 10% by weight based on the dry weight of the cotton padding. 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. Next, in the second heat treatment step, for example, heat treatment is performed at 120 to 200° C. for about 1 second to 20 minutes to cure the silicone resin. A long fiber batting is thus obtained.

A textile product of the present invention is a textile product comprising any one of the quilting fabrics described above. Textile products are suitable for clothing such as jackets, pants, and spats, and can also be used for hats, mufflers, ear pads, throws, neck warmers, cushions, futons (skin blankets), sleeping bags, and the like.

Description will be made below with reference to the drawings. In the following drawings, the same symbols indicate the same items. FIG. 1A is a schematic plan view of a quilting cloth according to one embodiment of the present invention, and FIG. 1B is a sectional view taken along line II of the same. The quilting cloth 1 is filled with fiber bundles 3 in which a plurality of long fiber fillings are arranged in one direction in a side fabric 2 . Stitches 4 a to 4 d are discontinuously inserted from the surface of the side fabric 2 in the same direction as the length direction of the fiber bundle 3 so as to pass through any part of the fiber bundle 3 . In this example, stitches 4d and below of the adjacent fiber bundle are arranged in the same cycle as stitches 4a-4c. That is, in FIGS. 1A-B, the stitch patterns of adjacent fiber bundles are identical. Both ends of the fiber bundle 3 are sewn with both end stitches 5a and 5b from above the side fabric. As a result, even if the stitches are shortened, the movement of the batting can be suppressed. In addition, the side fabric portion between stitches (the side fabric portion without stitches) is flat, and the apparent bulkiness can be improved.

FIG. 2A is a schematic plan view of the quilting cloth 6 of the comparative example, and FIG. 2B is a sectional view taken along the line II-II. The stitches 7a-7b are entered continuously.

FIG. 3 is a schematic perspective view of the quilting cloth 1 of FIG. Side ground portions between stitches (side ground portions without stitches) are flat portions 8a and 8b, which can improve apparent bulkiness. On the other hand, the quilting cloth 6 of the comparative example shown in FIG. 4 has stitches 7a and 7b continuously, so that the flat portion is small and the cloth is not bulky.

FIG. 5 is a side view photograph of a fiber bundle in which a plurality of long fiber battings are put together to fill a quilting cloth in one embodiment of the present invention. In this embodiment, a fiber bundle composed of fifteen long fiber battings is shown.

FIG. 6 is a side view of one long-fiber batting used in one embodiment of the present invention. In the long-fiber batting 10, constituent fibers of the core yarn 11 and the filament yarn 12 are entwined with each other, and the filament yarn 12 is opened to partially form a loop-shaped fiber. No fusing process.

FIG. 7 is a schematic illustration showing a method of manufacturing the long-fiber batting used in one embodiment of the present invention. A core yarn 24a is pulled out from the wound body 24, and a filament yarn 25a is pulled out from the wound body 25, passed through two feed rollers 26, 27 and a yarn guide 28, and supplied to the air interlacing device 20. - 特許庁When the compressed air 21 is supplied to the air entangling device 20, the fibers in the yarn path 29 are opened or swirled to entangle each other. 22 is a mixed fiber entangled yarn (long fiber batting). The core yarn supply speed is 10 to 200 m/min, the flower yarn supply speed is 20 to 10,000 m/min, the winding speed is 10 to 200 m/min, and the air pressure is 0.01 to 1.0 MPa. After passing through the delivery roller 23, the yarn is wound around the winding body 30. - 特許庁This method is advantageous in that the yarn winding speed can be increased to, for example, 20 to 1500 m/min, resulting in high productivity.

EXAMPLES The present invention will be described in more detail with reference to the following examples. It should be noted that the present invention is not limited to the following examples.

(Example 1)
Using the manufacturing apparatus shown in FIG. 7, polyester (PET) multifilament fibers (total fineness 33 dtex, number of filaments 18, trade name “Silmy” manufactured by Unitika) are used as core yarns, and PET multifilament fibers (total fineness 40 dtex, 12 filaments, trade name "Aerocapsule" manufactured by Teijin Ltd.), supplied one to each of the two feed rollers of the air interlacing device, core yarn supply speed 50 m / min, filament yarn supply After performing a mixed fiber entangling treatment with an air pressure 0.4 MPa entangling nozzle at a speed of 800 m/min and a winding speed of 55 m/min, the yarn passed through the delivery roller was wound as it was to obtain an air entangled yarn.

Next, in the silicone resin spraying step, a silicone resin was sprayed. As the silicone resin, bulky silicone "TERON E 530" and soft silicone "TERON E 731" and "TERON E 722" manufactured by Matsumoto Yushi Seiyaku Co., Ltd. were used as a mixed aqueous solution of three types. The spray amount was 3.0 wt % of the cotton padding in terms of dry weight. 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.

As shown in FIG. 6, in the obtained long-fiber batting, constituent fibers of the core yarn 11 and the filament yarn 12 are entangled with each other, and the filament yarn 12 is opened to partially form a loop-like fiber. The fibers were opened to form partially looped fibers. The weight per 1 m of this long fiber batting was 0.2 g.

This long-fiber batting was cut into lengths of about 30 cm, and 15 of them were put together to form one fiber bundle, thereby producing a stitched cloth 1 shown in FIGS. 1A-B and 3. FIG. The size of the stitch cloth 1 was 30 cm in length and 28 cm in width, and the fiber bundles were arranged in the longitudinal direction in the side fabric. The width of one fiber bundle was about 4 cm. The length of each stitch 4a-4d was 6 cm and the length between stitches was 3 cm. The weight of the stitch cloth 1 was 17 g (about 7 g of batting weight and about 10 g of side cloth weight). As shown in FIG. 3, the stitched cloth 1 has flat portions 8a and 8b in the side portion between the stitches (the side portion without stitches), thereby improving the apparent bulkiness. Also, using a household washing machine, the fabric was washed with water using a commercially available detergent (manufactured by Kao Corporation, trade name "Attack"), rinsed twice, dehydrated and dried. After repeating this washing five times, the batting was inspected by hand for unevenness. As a result, there was no unevenness of the batting.

(Comparative example 1)
As shown in FIGS. 2 and 4, the same procedure as in Example 1 was performed except that the stitches 7a-7b were continuously inserted. As a result, there were few flat portions and the film did not become bulky.

The stitched cloth of the present invention suppresses the movement of the batting and has a good apparent bulkiness, so it is suitable for clothes such as jackets, pants, and spats. It can also be used for neck warmers, cushions, futons (skin duvets), sleeping bags, and the like.
