Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to the improvement of bedding.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, in order to ensure the heat retention of bedding such as comforters, the bulk of the batting has been increased to increase the amount of air held in the batting.

Then, as a means to maintain the bulk of the filling and prevent the movement of the filling, the upper and lower side fabrics 1 and 2 were stitched vertically and horizontally to form a plurality of sections 3 within the side fabric, as shown in Figure 5. It is known that a so-called normal quilt is formed and the compartment 3 is filled with batting 4.

By the way, the above-mentioned ordinary quilt has the disadvantage that the five seams lack sublimeness and hold a small amount of air, resulting in a lack of heat retention.

Therefore, in order to solve the above-mentioned drawbacks of the ordinary quilt, as shown in FIG.
A plurality of cubic-shaped partitions 9 are formed in the side fabric in a checkerboard pattern by sewing strip-shaped partition cloths 8 in the thickness direction in the longitudinal and horizontal directions, respectively, and filling the partitions 9 with batting 10.
So-called three-dimensional quilts are known.

However, although the above-mentioned three-dimensional quilt solves the problem of sublimeness and air retention in the seams, the sequence and work of sewing the partition cloth 8 to the back surfaces of the upper and lower fabrics 6 and 7 are complicated and time-consuming. There was a problem that production efficiency was poor due to the high cost.

In addition, it is known that when bedding has pleats such as gears formed on the surface of the side fabric, the side fabric becomes elastic, increasing the storage capacity of the batting, and retaining air between the pleats, increasing heat retention. It is being

However, for the above-mentioned regular quilts or three-dimensional quilts, it is technically difficult to form pleats and sew them while quilting the side fabric, which requires a lot of effort, poor production efficiency, and causes high costs. There was a problem with this.

This idea was made in view of the above circumstances,
Not only can sections be easily formed within the side fabric, but pleats such as gears can also be easily formed at the seams of the quilt.Furthermore, the side fabrics touch each other at the boundaries of each section, which improves air retention at the seams. This provides bedding with improved heat retention.

[Means for solving problems]

The bedding according to this invention is a bedding in which the batting is stored in the side fabric made by overlapping the upper and lower side fabrics, and the quilting is sewn to the side fabric in multiple rows in at least one of the vertical, horizontal or diagonal directions. The lower fabric is made of heat-shrinkable fibers that are heat-shrinkable in at least one direction of the weft or the warp, and the quilted portion is formed with pleats due to contraction of the heat-shrinkable fibers.

〔Example〕

Examples of the bedding according to this invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a comforter, which is one of the bedding according to this invention, seen from the front side, and FIG. 2 is a partially cutaway view. In the figure, numeral 11 is the upper fabric, and 12 is the lower fabric.

The upper and lower fabrics 11 and 12 are sewn together at their peripheral edges, and quilting 13 intersects with each other in a diagonal direction with respect to the longitudinal direction of the comforter.
is applied, and the quilting 13 part has pleats 1.
4 is formed, and a plurality of sections 15 are formed.

Each section 15 is filled with wool cotton as a filling 16.

Further, as shown in FIGS. 1 and 2, the upper fabric 11 of each section 15 is raised, and the upper fabric 11 is in contact with each other at adjacent portions of each section 15.

Further, as shown in FIG. 3, the lower fabric 12 is woven using polyester fibers, which are heat-shrinkable fibers, as the weft 17 and warp 18.

Next, a method for manufacturing the above-mentioned comforter will be explained. First, the peripheral edges of the upper fabric 11 and the lower fabric 12 are sewn together to form a side fabric, and the batting 1 is placed inside this side fabric.
Store 6 wool cotton.

Furthermore, quilting 13 is applied to the upper and lower fabrics 11, 12 and the batting 16 so as to intersect each other diagonally with respect to the longitudinal direction of the futon.

Next, heat the futon for approximately 120 minutes in a heating room, etc.
Heat to ~150℃. Due to the above heating, the weft 17 and warp 18 of the lower fabric 12 are each approximately 1/2
shrinks to

Due to this heat shrinkage of the lower fabric 12, the upper fabric 11
shrinks along the seam line of the quilting 13, along the weft 17 and warp 18 directions, and pleats 14 are formed. Furthermore, since the lower fabric 12 of each section 15 contracts, the area of the upper fabric 11 becomes larger than that of the lower fabric 12, and each section 15 swells at adjacent portions and comes into contact with each other.
Therefore, air can be retained even in adjacent portions at the boundaries between the sections 15 without creating large gaps.

Furthermore, hem processing 19 is applied to the peripheral edge of the futon.

According to the comforter of the above example, the lower fabric 1
2 is woven using heat-shrinkable polyester fibers as the weft 17 and warp 18, so it shrinks when heated, and the upper fabric 11 contracts along the quilting 13, weft 17 and warp 18, and becomes pleated. 14 are formed and each compartment 1
Every 5 minutes, the upper fabric 11 rises and comes into contact with each other in adjacent areas of each section 15, so that the loftiness and air retention are maintained in this quilting 13 area. Therefore, the bulkiness is maintained in the quilted portion 13, and air is retained, improving heat retention.

In addition, as mentioned above, the weft 17 of the lower fabric 12,
Since heat-shrinkable polyester fibers are used for the warp threads 18, the pleats 14 and the bulges of the upper fabric 11 can be easily created by a simple method of heating.

In addition, in the above embodiment, quilting 13
The sheets were applied diagonally to the longitudinal direction of the futon so as to intersect with each other, but as shown in Figure 4, the wavy waves were formed in multiple rows parallel to the longitudinal direction, with parallel troughs and crests. Quilting 13 may be applied so as to butt each other.

Further, the quilting 13 may be applied only in one direction, vertically, horizontally, or diagonally.

Further, heat-shrinkable fibers may be used only for either the weft 17 or the warp 18 of the lower fabric 12, and the fibers are not limited to polyester as long as they are heat-shrinkable.

Further, the shrinkage rate of the heat-shrinkable fiber is not limited to 1/2, but can be selected as appropriate.

Furthermore, bedding to which this invention can be applied includes various types of bedding such as comforters, mattresses, and seat cushions, and it goes without saying that the lower fabric surface of the bedding in the above embodiment can be further covered with another fabric.

Furthermore, the type of batting for the bedding is not limited to those of the above embodiments.

[Effects of the invention] As explained above, the bedding according to this invention is a bedding in which the upper and lower side fabrics are overlapped and the batting is stored in the side fabric, and the side fabric has at least one vertical, horizontal or diagonal direction. Since the lower fabric is made of heat-shrinkable fibers that are heat-shrinkable in at least one direction of the weft or the warp, the quilting process with pleats can be easily performed by heating. The treated bedding can be easily manufactured.

In addition, as the lower fabric contracts, the upper fabric swells up, and the upper fabric comes into contact with each other in the adjacent areas of each compartment, so the bedding retains its sublime quality even in the quilted areas, resulting in excellent heat retention.

Furthermore, since the manufacturing process is simple, costs can be reduced compared to conventional methods.
