Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the side fabric of bedding, and particularly to the side fabric of bedding in which pleats such as serrations are applied to the seams of a quilt.

[Prior art and its problems] Conventionally, in order to ensure the heat retention of comforters, the bulk of bedding batting has been increased to increase the amount of air held in the batting.

In order to achieve the above-mentioned bulkiness of the filling and to prevent the movement of the filling, conventionally, upper and lower side fabrics 1 and 2 are stitched vertically and horizontally to form a plurality of sections 3 within the side fabric, as shown in FIG. Alternatively, as shown in FIG. 7, strip-shaped partitioning cloth 4 is sewn vertically and horizontally in the thickness direction to the upper and lower side fabrics 1 and 2, respectively, and a plurality of cubic-shaped sections 5 are formed in the side fabrics as base materials. There is known a futon which is formed into a shape and in which the sections 3 and 5 are filled with batting 6.

By the way, the upper and lower side fabrics 1 shown in FIG. 6 above,
The so-called ordinary quilt in which stitches are sewn is not bulky at the seam 7 and is thin, so it retains a small amount of air and has the disadvantage of lacking heat retention.

Furthermore, the so-called three-dimensional quilt shown in FIG. There was a problem in that the work of forming a plurality of sections 5 in a grid pattern took time and effort, resulting in poor production efficiency.

In addition, when bedding has pleats such as gears formed on the surface of the side fabric, the elasticity of the side fabric increases the storage capacity of the batting, and air is retained between the pleats, increasing heat retention. be.

However, in the ordinary quilt and three-dimensional quilt shown above, the upper and lower fabrics 1 and 2 forming the sections 3 and 5 are
The surface of the fabric is in a stretched state, and there are no folds such as gears, so even if the batting is stored, the upper and lower fabrics 1 and 2 will not expand any further, and the volumes of compartments 3 and 5 will remain the same, with the amount of air retained. It never increases.
Moreover, it is technically difficult to sew the upper and lower fabrics 1 and 2 vertically and horizontally while forming pleats such as gears at the 7 seams of the upper and lower fabrics 1 and 2, and it is time-consuming to manufacture. In addition to being inefficient and resulting in high costs, the ordinary quilt shown in FIG. 6 still has the problem of bulkiness at the seam 7 portion.

This invention was developed in view of the above circumstances, and it is possible to easily form quilted sections in the side fabric, and also to easily form pleats such as gears at the seams of the quilt. To provide a side fabric for bedding which has good heat retention by having the side fabrics in contact with each other to improve air retention in the seam portion.

[Means for solving the problem] The side fabric of the bedding according to this invention has heat shrinkable members interposed in the vertical and horizontal seams between the upper and lower side fabrics,
The seam portion of the side fabric is formed with pleats formed by shrinkage due to heating of the heat-shrinkable member.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings. FIG. 1 is a plan view of this embodiment before forming pleats, which will be described later, on the side fabric, and FIG. 2 is a partial cross-sectional view taken along the line in FIG. 1. In the figure, numeral 8 is the upper fabric, numeral 9 is the lower fabric, and numeral 10 is a seam in which the upper and lower fabrics are sewn vertically and horizontally.These seams 10 form a plurality of compartments 11 in the side fabric for storing batting. It has been done.

Between the upper and lower side fabrics 8 and 9, a rectangular shrinkable member piece 13a, which is a heat-shrinkable member 13, extends along the seam 10 in the length direction of the side fabrics 8 and 9, centering on the intersection 12 of the seam 10. Furthermore, shrinkable member pieces 13b are interposed in the width direction and sewn together with the upper and lower fabrics 8 and 9.

As shown in FIG. 3, the shrinkable member pieces 13a and 13b are each formed by weaving warps 14 made of polypropylene fibers and wefts 15 made of polyester fibers.

In this case, the warp yarns 14 have a higher thermal shrinkage rate than the weft yarns 15.

By heating the side material formed as described above to about 120°C to 150°C with an iron or a heating chamber, the warp yarns 14, which have a large heat shrinkage rate, are shrunk by about 50% in the longitudinal and lateral directions centering on the intersection 12. The side fabrics 8 and 9 are shrunk and many pleats are formed along the seam 10.

In the side fabric of the above embodiment, the shrinkable member pieces 13a and 13b are interposed between the upper and lower fabrics 8 and 9, and the upper and lower fabrics 8 and 9 are sewn in the vertical and horizontal directions, so that the fabrics can be simply heated. It is possible to easily manufacture a side fabric with pleated quilting, and it is possible to reduce labor and production efficiency and reduce costs.

Furthermore, when the batting 17 is stored in this side fabric, the upper and lower fabrics 8 and 9 of the adjacent compartments 11 bulge and come into contact with each other, as shown in FIGS. The result is similar to that obtained by increasing the bulk of the ivy portion by itself, and air is retained in the seam 10 portion and air is also retained in the pleat 16 portion, resulting in bedding with good heat retention.

Regarding the shrinkable member pieces 13a and 13b, either the heat shrinkage rate of the weft yarn 15 in the direction perpendicular to the vertical and horizontal seams 10 is increased, or the width dimension W of the heat shrinkable member 13 is increased, or the heat shrinkage rate is increased. If the width dimension W is increased, the shrinkage will increase, and the upper fabric 8 and lower fabric 9 forming each section 11 will shrink significantly.

As a result, the number of bulges and folds 16 at the seam 10 portion increases, further increasing air retention and heat retention.

Furthermore, by widening the width of the shrinkable member pieces 13a and 13b and pressing them into two folds with an iron or the like from between their center lines, the bulkiness at the seam 10 portion can be further increased, and heat retention can be increased. .

Further, instead of forming a rectangular shrinkable member piece with the warp 14 and weft 15 heat shrinkage rates matched, a band-shaped heat shrinkable member may be sewn along the entire line of the seam 10.

This configuration simplifies the structure and facilitates manufacturing, thereby reducing costs.

In addition, heat-shrinkable members are not limited to those woven with warp and weft, but may be uniaxially stretched or biaxially stretched with different heat shrinkage rates in the longitudinal and lateral directions, or those that have the same shrinkage rate in the longitudinal and lateral directions. It may also be made of thin synthetic resin.

Further, in order to manufacture bedding using the side fabric of this embodiment, the batting 17 may be stored in each compartment 11 after the side fabric is heated to form the pleats 16, or the filling 17 may be stored in each compartment 11 before the pleats 16 are formed. The pleats 16 may be formed by storing the batting 17 and then heating the entire bedding.

Alternatively, the heat-shrinkable member may be interposed only along either the longitudinal seam 10 or the widthwise seam 10 of the futon, and the pleats 16 may be formed only in one direction, the longitudinal direction or the width direction.

Furthermore, the material, shrinkage rate, heating temperature, etc. of the heat-shrinkable member are not limited to those in the examples.

Further, the side material according to this embodiment can be applied to all quilted bedding such as futons, seat cushions, and pillows.

[Effects of the invention] As explained above, the side fabric of the bedding according to this invention has upper and lower side fabrics sewn vertically and horizontally to form a plurality of compartments for storing the batting. A heat shrinkable member is interposed in the eye part, and folds are formed in the seam part of the side material by contraction due to heating of the heat shrinkable member, so that folds such as gears can be formed together with the divisions with a simple operation. I can do it. Therefore, production efficiency is high and production can be reduced.

In addition, by changing the shrinkage rate, length, and width dimensions of the heat-shrinkable material, it is possible to increase the swell of the upper and lower fabric surfaces at the seam of each section to ensure bulkiness, and the side fabrics that touch each other at the seam of each section can be By eliminating the gaps between the battings, when the batting is stored, it is possible to secure the amount of air retained and maintain heat retention, and at the same time, folds are formed at the seams due to contraction due to heating of the heat-shrinkable material. This has the effect of increasing the amount of air retained and ensuring heat retention.
