Abstract

<P>PROBLEM TO BE SOLVED: To provide a feather fall-off preventing quilt structure improved not only in flexibility, stretchability, air permeability and humidity permeability but also in the feather blow workability of a cloth bag. <P>SOLUTION: The feather fall-off preventing quilt structure 5 is constituted by forming a foamed polyurethane film with a thickness of 15-60 μm, the air permeability of 5 cm<SP>3</SP>/cm<SP>2</SP>/s or higher and a humidity permeability of 500 g/m<SP>2</SP>hr or lower into the cloth bag 2 and blowing a feather 1 into the cloth bag 2 to fill the cloth bag. In particular, the thickness of the foamed polyurethane film is set to 40-60 μm and a foam diameter is set to 1.5-10 μm. Furthermore, a feather fall-off preventing effect can be further enhanced by forming a cotton layer 6 or a tulle net layer 7 on the inner surface of the cloth bag. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a feather quilting structure that is flexible, stretchable, durable, breathable, and has good feather blowing workability.

Down jackets and down futons have a problem that the feathers come out from the texture or seam of the cloth bag that wraps the feathers (hereinafter simply referred to as the cloth bag) due to long-term use. As a countermeasure, the cloth bag that contains the feathers has a high weaving density. There have been proposed ones employing a knit having a high knitting density, or ones employing a fabric woven with fibers having a surface coated with a viscous resin composition such as polyurethane.

  Although the above-mentioned proposal was able to obtain the effect of preventing feather loss, the suppleness of the cloth bag was impaired and the touch was poor.

  In addition, attempts have been made to apply polyurethane, polytetrafluoroethylene, etc. to the surface of the fibers forming the cloth bag, but this will impair the flexibility, breathability, and moisture permeability of the cloth bag, resulting in a decrease in breathability. As a result, there is a problem that the workability of blowing feathers is lowered.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention has an object to provide a quilt structure that prevents losing feathers and has good workability for blowing feathers into a cloth bag, as well as flexibility, stretchability, breathability, and moisture permeability. And

In order to solve the above-mentioned problems, the present invention uses a foamed polyurethane film of open cells having a thickness of 15 μm to 60 μm, an air permeability of 5 cm ³ / cm ² / s or more and a moisture permeability of 500 g / m ² · hr or less. In particular, the open-cell foamed polyurethane film has a thickness of 40 to 60 μm and a foam diameter of 1.5 to 10 μm. Further, a cotton layer or a tulle net layer can be formed on the inner surface of the cloth bag.

  Furthermore, the feather quilting structure can be used as a material for a feather futon or a down jacket.

  According to the present invention configured as described above, first, since the air permeability of the open-cell foamed polyurethane film is good, the filling operation of feathers (especially in blowing filling) is easy and can be performed without unevenness.

  Secondly, since the open-cell foamed polyurethane film has good flexibility, stretchability, breathability, and moisture permeability, it is comfortable to wear or sleep, and can be kept in a comfortable state without stuffiness during use.

  Thirdly, by specifying the thickness and foam diameter of the open-cell foamed polyurethane film as described above, the cross-sectional structure is complex, and open-cells like a fine mesh are formed. The effect of preventing feathers from slipping out can be obtained while being good, and the effect of preventing feathers from slipping out is further improved by forming a cotton layer or tulle net layer on the inner surface of a cloth bag made of foamed polyurethane.

Next, embodiments of the present invention will be described with reference to the drawings. In FIG. 1 (a), the open-cell foamed polyurethane film constituting the cloth bag 2 employs XOLTEX / PX-550 manufactured by DIC Corporation. According to the company's data, the characteristics of this polyurethane foam film are as follows. The foam diameter is 1.5 to 10 μm (observation with an electron microscope × 500), the air permeability is 5 to 8 cm ³ / cm ² / s, and the moisture permeability is 200 to 400 g / m ² · hr.

  The above-mentioned open-cell foamed polyurethane film is used as a raw material to leave a filling (blowing) port to form a cloth bag 2. The cloth bag 2 is filled with feathers 1 by usual means, and further, a protective cloth 3 is overlapped and the peripheral edge is stitched. The feather 1 was distributed uniformly in the cloth bag 2 and subjected to post-quilting 4 to obtain a prototype 5.

  In addition, in the filling (blowing) operation of the feathers, it was confirmed that the workability was very good because the foamed polyurethane film had good air permeability and the feathers were uniformly filled (bloated) into the cloth bag 2.

  Moreover, in the said Example, as shown in FIG.1 (b) on the inner surface of the cloth bag 2, cotton with an apparent thickness of 0.5-1.0 mm is bonded together, or as shown in the cotton layer 6 or FIG.1 (c). When the tulle net layer 7 is formed by laminating tulle nets (the thickness of the yarn, the number of yarns held, the number of hits per centimeter), it is possible to obtain a better feather fall-out preventing effect.

  As shown in FIG. 2, the cloth bag 2 is sewed with a foamed polyurethane film of XOLTEX / PX-550 made by DIC Corporation, leaving a blow-in port, as in the prototype of FIG. Thus, the feather 1 is filled (blown), and then the protective cloth 3 is overlapped only on one side and the peripheral edge is stitched, and the feather 1 is uniformly distributed in the cloth bag 2 and the rear quilting (press sewing) 4 is performed. Then, the protective cloth 3a was further sewn to make a prototype 5a.

  FIG. 3 is a prototype of the cold protection jacket J with the quilt structure 5 of FIG. When this jacket J was tried on and checked for comfort, stuffiness, and occurrence of feather loss, all obtained good evaluations.

  It is needless to say that the quilt structure shown in FIG. 2 can also be sewn to the jacket, and that the quilt structure shown in FIGS.

  As described above, according to the present invention, it becomes possible to completely prevent feathers from falling without using a fabric having a high weaving density or knitting density, and the open-cell foamed polyurethane film used for the cloth bag is flexible and stretchable. It has good performance, breathability and moisture permeability, is comfortable to wear, and the workability of filling (blowing) feathers into a cloth bag is improved, so that the industrial utility value is extremely high.
