  • the present invention relates to a multilayer-type comforter and a method for manufacturing the same.
  • Patent Documents 1 to 4 Examples of this type of multilayer-type comforter are described in Patent Documents 1 to 4.
  • these conventional comforters have three fabrics, namely, an outer fabric, an interlining and a backing fabric. Feathers are disposed between the outer fabric and the interlining. A filling material is disposed between the interlining and the backing fabric.
  • the outer fabric and the interlining are joined by baffle-box quilting, and the interlining and the backing fabric are joined by sewn-through quilting.
  • baffles should be spaced apart widely or a large slit has to be formed in each baffle in advance so as to prevent the sewn-through quilting from sewing the baffles of the baffle-box quilting to lay them down.
  • An object of the present invention is to solve the above-described problems of the conventional technique, and a multilayer-type comforter having at least three fabrics as first to third fabrics, a first raw material being interposed between the first fabric and the second fabric, a second raw material being interposed between the second fabric and the third fabric, the first fabric and the second fabric being joined by a baffle-box quilting with a baffle interposed therebetween, the second fabric and the third fabric being joined by a sewn-through quilting, the baffle-box quilting and the sewn-through quilting being different in arrangement is characterized in that the baffle formed on the second fabric is sewn to the second fabric by the sewn-through quilting and then cut to stand up from the second fabric.
  • the first raw material is a blown filling
  • the second raw material is a sheet-like filling material
  • the first fabric and the third fabric are different in air permeability.
  • stitches of the sewn-through quilting reach the periphery of the third fabric by quilting on a comforter sewing machine.
  • At least part of the sewn-through quilting can be made curvilinear.
  • the horizontal interval of the sewn-through quilting is made wider at the right and left sides and narrower at the center, and the horizontal interval of the baffle-box quilting is made wider at the center and narrower at the right and left sides.
  • the blown filling is a short fibrous raw material, such as feathers, granulated wool, or polyester.
  • the sheet-like filling material is one of a sheet-like cotton material obtained by bringing short fiber cotton into the state where cotton fibers are entangled together by carding, needle punch or the like and a filling material obtained by shaping long fibers, such as floss silk fibers or polyester long fibers, into the form of a sheet.
  • a fourth fabric is disposed on the outside of the first fabric, the second raw material is interposed between the first fabric and the fourth fabric, and the first fabric and the fourth fabric can be joined by the sewn-through quilting.
  • the first raw material and the second raw material can be a blown filling.
  • a method for manufacturing a multilayer-type comforter of the present invention having at least three fabrics as first to third fabrics, a first raw material being interposed between the first fabric and the second fabric, a second raw material being interposed between the second fabric, and the third fabric, the first fabric and the second fabric being joined by a baffle-box quilting with a baffle interposed therebetween, the second fabric and the third fabric being joined by a sewn-through quilting, the baffle-box quilting and the sewn-through quilting being different in arrangement is characterized in that the baffle formed on the second fabric is sewn to the second fabric by the sewn-through quilting and then cut to stand up from the second fabric.
  • the sewn-through quilting can be sewn on a comforter sewing machine.
  • the operation of arranging baffles of a baffle-box quilting is facilitated, and airtight independency of quilt boxes is not impaired.
  • Fig. 1 shows a two-layer-type comforter shown as an example of a multilayer-type comforter.
  • Figs. 2 and 3 show cross sections of the two-layer-type comforter.
  • the two-layer-type comforter has three fabrics, namely, first to third fabrics 1, 2 and 3.
  • First fabric 1 is an outer fabric
  • second fabric 2 is an interlining
  • third fabric 3 is used as a backing fabric. Therefore, third fabric 3 is generally in contact with a human body.
  • first fabric 1 can also be used in a manner contacting a human body depending on the season.
  • a first raw material 4 is disposed between first fabric 1 and second fabric 2.
  • a second raw material 5 is disposed between second fabric 2 and third fabric 3.
  • First fabric 1 and second fabric 2 are joined by a baffle-box quilting 6.
  • Second fabric 2 and third fabric 3 are joined by a sewn-through quilting 7.
  • Baffle-box quilting 6 and sewn-through quilting 7 are different in arrangement.
  • the above-mentioned "sewn-through quilting 7" directly sews fabrics.
  • the above-mentioned "baffle-box quilting 6" joins fabrics with a baffle 8 interposed therebetween, and can leave a wide space between first fabric 1 and second fabric 2.
  • a first baffle 8a sewn or adhered to the rear surface of first fabric 1 and a second baffle 8b sewn or adhered to the upper surface of second fabric 2 are sewn or adhered to each other to join first fabric 1 and second fabric 2.
  • Second baffle 8b of the baffle-box quilting formed on second fabric 2 is sewn to second fabric 2 by sewn-through quilting 7 and then cut to stand up from second fabric 2.
  • First raw material 4 is a blown filling.
  • Second raw material 5 is a sheet-like filling material. However, second raw material 5 can also be a blown filling similar to the first raw material.
  • the blown filling is a short fibrous raw material, such as feathers, granulated wool, or polyester.
  • the sheet-like filling material is a sheet-like cotton material obtained by bringing short fiber cotton into the state where cotton fibers are entangled together by carding, needle punch or the like, or a filling material obtained by shaping long fibers, such as floss silk fibers or polyester long fibers, into the form of a sheet.
  • first raw material 4 shall be feathers.
  • Second raw material 5 is absorbent, heat-releasable cotton composed of 50% polyester and 50% cellulosic fiber, for example, and is formed in the form of carded filling.
  • First fabric 1 and third fabric 3 shall be different in air permeability.
  • first fabric 1 has an air permeability of 1.5 cm 3 /cm 2 ⁇ s
  • third fabric 3 has an air permeability of 3.5 cm 3 /cm 2 ⁇ s.
  • first fabric 1 At 1.5 cm 3 /cm 2 ⁇ s plays a role to prevent the feathers as first raw material 4 from being blown off and to prevent heat from escaping from the upper part of the comforter.
  • third fabric 3 By setting the air permeability of third fabric 3 at 3.5 cm 3 /cm 2 ⁇ s, insensible perspiration from a human body is likely to pass through third fabric 3, which improves second raw material 5 in absorbency and heat release capability. Thus, the effect of reducing humidity in a bed can be obtained.
  • first fabric 1 and third fabric 3 fabrics of the same air permeability can be used for first fabric 1 and third fabric 3.
  • first fabric 1 and third fabric 3 should be different in air permeability, it is preferable to set first fabric 1 at 0.5 to 3.0 cm 3 /cm 2 ⁇ s, third fabric 3 at 2.0 to 5.0 cm 3 /cm 2 ⁇ s, and the difference in air permeability between first fabric 1 and third fabric 3 at more than or equal to 1.0 cm 3 /cm 2 ⁇ s.
  • Figs. 4 to 11 are drawings showing manufacturing steps of the above-described two-layer-type comforter.
  • baffle tape 8b is attached to the upper surface of the interlining which is second fabric 2.
  • Baffle tape 8b is sewn lengthwise and crosswise such that 5 ⁇ 6 boxes are formed, for example.
  • This baffle tape 8b constitutes above-described second baffle 8b.
  • baffle tape 8a is also sewn on the rear surface side of first fabric 1 such that 5 ⁇ 6 boxes are formed (see Fig. 9 ).
  • boxes are not limited to 5 ⁇ 6, but can be patterned infinitely as, for example, 3 ⁇ 5.
  • absorbent, heat releasable carded filling as second raw material 5 is disposed between second fabric 2 and third fabric 3, so that three overlap one another.
  • second fabric 2, second raw material 5 and third fabric 3 overlapping one another are affixed on a sewing table of a comforter sewing machine. This affixing is accomplished by holding the peripheries of the fabrics with clips provided around the sewing table. For a grip margin of the clips, second fabric 2 and third fabric 3 have been cut out to be slightly larger than the dimensions of a comforter product. For example, if product dimensions are 150 ⁇ 210 cm, fabrics 2 and 3 are cut out into 160 ⁇ 221 cm.
  • sewn-through quilting 7 is made on a comforter sewing machine. That is, 6 ⁇ 7 boxes are quilted. This sewn-through quilting 7 is made at a position displaced from the arrangement of baffle tape 8b. Therefore, stitches of sewn-through quilting 7 will sew baffle tape 8b.
  • boxes of the sewn-through quilting are not limited to the above-described 6 ⁇ 7 pattern, but can be patterned infinitely.
  • the fabrics are removed from the sewing table, and the grip-margin portion on the peripheries of the fabrics is cut away.
  • Fig. 6 shows a semi-finished product from which the peripheries have been cut away.
  • baffle tape 8b is laid down on the upper surface of second fabric 2, since baffle tape 8b has been sewn by sewn-through quilting 7.
  • the stitches of sewn-through quilting 7 reach the peripheries of fabrics 2 and 3.
  • baffle tapes 8b and 8b are cut with scissors, a cutter knife, or the like to form incised parts 9.
  • Baffles 8b can stand up from the surface of second fabric 2 by way of these incised parts 9.
  • incised parts 9 are formed after sewing of sewn-through quilting 7, the spacing between incised parts 9 can be narrowed as much as possible, which ensures airtight independency of quilt boxes.
  • Baffle tape 8b is cut to raise baffles after forming sewn-through quilting 7, which means the arrangement and sewing of baffle tape 8b can be carried out freely without being restricted by sewn-through quilting 7. This facilitates the operation of arranging baffles of the baffle-box quilting.
  • Fig. 8 shows the state in which second baffles 8b are raised.
  • Baffles 8b of baffle-box quilting 6 formed on second fabric 2 are sewn to second fabric 2 by sewn-through quilting 7, and then cut to stand up from second fabric 2.
  • first baffle 8a formed on the lower surface of first fabric 1 and second baffle 8b are sewn together.
  • first fabric 1, second fabric 2 and third fabric 3 are sewn together.
  • the outer peripheries are partly not sewn to form filling openings 10 at which the first raw material is to be blown.
  • a nozzle 11 is inserted into above-described filling opening 10, and a given amount of feathers as first raw material 4 is blown to fill the boxes formed between first fabric 1 and second fabric 2. Finally, filling openings 10 are sewn to complete the two-layer-type feather comfort shown in Fig. 1 .
  • sewn-through quilting is made on a comforter sewing machine in the above-described embodiment, this is not a limitation, but it may be made on a lock stitch sewing machine. It is also possible to make only longitudinal lines of the sewn-through quilting on a comforter sewing machine and to make horizontal lines of the sewn-through quilting on a lock stitch sewing machine.
  • Fig. 12 shows another embodiment of the present invention in which sewn-through quilting 7 formed on third fabric 3 has a curvilinear shape unlike the linear quilting of the above-described embodiment.
  • This sewn-through quilting 7 is made in a curvilinear shape or the shape of a broken line extending from the circumference of the comforter to the inner side toward the center but not reaching the center.
  • the shape of this sewn-through quilting 7 the shape described in Japanese Patent Laying-Open No. 2003-339501 can be adopted.
  • the remaining configuration is the same as that of the above-described embodiment.
  • the fit to the body is improved by shaping sewn-through quilting 7 to at least partially include a curve.
  • baffles of the baffle-box quilting formed on the second fabric is sewn to the second fabric by sewn-through quilting 7, and then cut to stand up from the second fabric. Therefore, even if sewn-through quilting 7 of any shape is adopted, the operation of arranging baffles will not become difficult. That is, regardless of the shape of sewn-through quilting 7, baffles of the baffle-box quilting can be arranged easily.
  • Fig. 13 shows another embodiment of the present invention.
  • the horizontal interval of sewn-through quilting 7 formed on third fabric 3 is made wider at the right and left sides and narrower at the center than at the right and left sides.
  • the horizontal interval of above-described baffle-box quilting 6 is made wider at the center and narrower at the right and left sides than at the center. More specifically, sewn-through quilting 7 is formed to provide 5 ⁇ 7 boxes, and baffle-box quilting 6 is formed to provide 5 ⁇ 6 boxes.
  • the quilting on the lower layer part to be in contact with the human body is arranged to be wider on both the sides and narrower toward the center, and in contrast, the quilting on the upper layer part is arranged to be narrower on both the sides and wider toward the center. Accordingly, as shown in Fig. 14 , the effect of increasing the likelihood that the comforter fits the human's body because the quilting is narrow at the center of the lower layer part while not impairing the warmth retaining property of the part just above the body because the quilting is narrow at the center of the upper layer part where a relatively large amount of filling is filled can be obtained.
  • Fig. 15 shows a three-layer-type feather comforter.
  • a fourth fabric 12 is disposed on the outside of first fabric 1 of the two-layer-type comforter shown in Fig. 1 .
  • Second raw material 5 is interposed between this first fabric 1 and fourth fabric 12.
  • First fabric 1 and fourth fabric 12 are joined by sewn-through quilting 7. The remaining configuration is the same as that of the above-described embodiment.
  • Fig. 16 shows flowcharts in the case of using a blown filling for the second raw material.
  • second fabric 2 and third fabric 3 are aligned to each other.
  • vertical lines of sewn-through quilting 7 are made on a comforter sewing machine or a lock stitch sewing machine.
  • a single horizontal line of sewn-through quilting 7 is made at the section near the center.
  • filling openings 10 are left open at the upper and lower sides.
  • the horizontal sides at which filling is not carried out are sewn together.
  • the filling is blown from both the upper and lower sides with blowing nozzle 11.
  • filling openings 10 are closed after filling. After leveling the filling uniformly, horizontal lines of sewn-through quilting 7 are made.
  • first raw material and the second raw material are the same blown filling, specific examples thereof can be different.
  • first raw material can be feathers
  • second raw material can be a short fibrous raw material, such as polyester.
