Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filling body having an excellent energy saving effect. More specifically, even if the thickness is quite thin, it has an excellent heat retention effect, so it requires considerably less batting.

This invention relates to a filling object that has many practical advantages such as being lightweight and having excellent appearance and design effects.

Traditionally, stuffed objects such as futons require heat retention.

The staple fibers are opened with cards, etc. and then made into a web.

This was either molded and placed in the side fabric, or it was once placed inside a bag-like body and then stored in the side fabric. However, with such conventional fillings.

When it comes to large padded objects such as quilts or tatatsubuttons, the inside fibers move, causing a so-called ``cotton-like'' phenomenon, which drastically reduces the heat retention effect. In addition, in order to increase heat retention, it was necessary to use a large amount of batting and increase the thickness.

For this reason, Publication No. 54-18429, Publication No. 54-18
As proposed in Publication No. 43o, a futon is known in which two sheets of quilted batting are overlapped and integrated at nine peripheral edges. However, since both sheets of such futons use quilted cotton, heat easily dissipates through the holes in the quilted parts, the overall feel is hard and lacks bulk, and the upper and lower stuffing objects tend to peel off in the center of the futon. However, it still does not have satisfactory characteristics.

The inventors of the present invention have conducted intensive studies to improve the above-mentioned drawbacks, and as a result, have arrived at the present invention.

In other words, the present invention relates to a stuffed article consisting of at least two layers of batting material, A and B layers.

B. The batting A contains fibers with a single fiber denier of 5d or less, and has one or more quilt rows within a square area of 40 square sides, and the quilt row is composed of the batting A and the batting A. It can be integrated with the side area.

The opening and filling body B include fibers with a single fiber denier of 5d or less, and at least one side is covered with a side material.

C. The batting bodies A and B covered with the side material are polymerized and integrated at one peripheral edge.

The filling object is characterized in that the central part is fixed and integrated at at least one place by a fixing means.

The stuffed body of the present invention is composed of at least two layers of filling, and the single fibers constituting the two layers of filling need to contain fibers with a fineness of 5d or less. By using thin denier fibers, the space formed in the batting is subdivided, forming many immobile air layers to prevent air convection and improve heat retention, as well as being soft and bulky. It is necessary to give a feeling. Thin fibers improve the warmth of children, but if they are too thin, the cotton will fall out from the side fabric.

This is undesirable because it causes sagging, and considering appropriate bulk and high performance, it is 0.8 to 3. D d is good. The fibers having a fineness of 5 d or less may be short fibers or long fibers, that is, filaments or tows. The amount of fibers with a fineness of 5d or less may be any amount for each of the batting bodies A and B, but
Preferably 50% by weight to improve the above effects.
That's all.

In the present invention, the batting A is made of a quilted stuffing, and the batting B is made of a stuffing that is not substantially independently quilted. However, the quilting density of batting A is.

40,anX It has one or more quilt rows within a square area of 40an (length x width). The area of such a square is indicated by the average value calculated from the entire area of the filling object. Preferably, effective quilting is one in which one or more pieces of quilting are included in each vertical strip within a square area of 2Q x 2Qcm, and particularly preferably, one or more quiltings are included in each vertical quilt within a square area of 10cm x 10an. Each toyo has one or more pieces of quilting. In this quilting, the batting body A and the side fabric of the batting body A are sewn together. By using such quilting and quilting density, it is possible to reduce the thickness of the batting body A, prevent the movement of fibers within the batting body A, improve the morphological stability, and further provide a beautiful appearance and improve the design effect. I can do it.

Next, the batting body B is a stuffed body that is substantially alone and not quilted, and at least one side of the batting body is covered with a side fabric. Substantially no quilting means that there are very few quilting rows compared to batting A, or
Or it means nothing at all. That is, if expressed as an average quilting row calculated from the entire area of the stuffing object defined as the filling material, it means less than one or no quilting row within an area of 40cm x 40an (vertical x horizontal).

Of course, there may be any number of fixing means such as point stitching or Japanese binding. Moreover, the phrase "at least one side is covered with a side fabric" means that at least the side that does not come into contact with the batting A has a side fabric, and of course the whole may be covered with a side fabric.

By having the batting body B having such a configuration, heat dissipation from the quilting area of the batting body A is prevented.

In addition, the filling object as a whole is given softness and bulkiness to a certain extent, and can improve its fit to the object to be kept warm. Therefore, when the side of the batting body B is placed on the human body side and used as a blanket, for example, it will fit the human body, and similarly, when the side of the batting body B is placed on the side of a kotatsu and used as a kotatsu futon, it will fit both the kotatsu and the human body that corresponds to the kotatsu. It has a unique effect. Due to this.

The heat insulating space inside the kotatsu is reduced, meaning that only a small volume of air needs to be heated, which requires less energy.

Next, the batting bodies A and B covered with the above-mentioned side fabric are overlapped and 1
It is integrated at the periphery and is also fixed at at least one location in the center. Such fixing means are sewing means.

Known methods such as snap fastening, zipper fastening, hook fastening, button fastening, and zipper fastening can be used, but quilting stitches and point stitches are preferable.

This is a method of sewing such as Japanese stitching. Most preferably, the center stitching is straight stitch quilting. If the quilting density is high, the effect of the present invention will be impaired, so it is preferable that the number of quiltings is one row or less on average per area of 4Qan x 40cm (length x width). For example 2mx2
In the case of a kotatsu futon of size m, the corners are quilted with two straight lines, -side 9Qam, 150(2), 1
It is best to quilt to about 80 square squares.

By fixing the periphery and the center, it is possible to prevent separation of the batting bodies A and B, making it possible to create an integrated stuffing body, and at the same time, it is possible to prevent the batting body B from shifting to cotton, resulting in a highly durable stuffing. It can be an object.

Furthermore, since an appropriate space can be formed between the batting bodies A and B, the heat retention properties can be further improved.

In a preferred filling material of the present invention, the single fibers constituting the filling material A or B are polyester. This is because it has excellent physical properties such as compression properties and durability, and also has the advantage that its shape does not change easily even when washed.

The polyester may be a normal solid fiber or a hollow fiber. Further, the cross section may be round or deformed, and furthermore, it may be a conjugate fiber, particularly a bimetal type conjugate fiber, spun from the same die hole. Preferred fibers are hollow or bimetallic composite fibers. This is because it has excellent heat retention properties and crimp properties.

When the fibers that make up the batting body become thinner than 2d.

Not only does it have poor passability through the card machine, but it also has poor entanglement when made into an aggregate.Furthermore, staples have a large number of fiber ends, which causes problems when removing cotton from the wrapping material. I can't stand it. Therefore, it is preferable to use filament fibers with very few fiber ends, and more preferably to apply a resin so that the fibers are partially or completely fixed to each other to form a batting.

Further, it is preferable that the single fibers constituting the batting material A or B of the present invention have a number of crimps of 70 or more. This prevents the phenomenon of cotton removal from the side fabric when using relatively fine fibers, improves the entanglement of the m-fibers, and improves processability and
This is to improve durability.

Further, it is preferable that the portion where the batting bodies A and B of the present invention are overlapped is made of a nonwoven fabric. Although it is possible to use a commonly used fabric as the side material, this is preferable for economical reasons since the nine overlapping portions do not appear on the outside.

Further, it is preferable that the batting material A or B of the present invention is web cotton made from card. This is to give it softness. If one of the materials is web cotton, the other material may be a blown cotton material.

By attaching a resin to the front or back surface of the filling material Ai and/or B, the morphological stability can be further improved and at the same time, a stable air layer can be ensured.

As a result, durability and heat retention can be improved. Furthermore, since the morphological stability is improved in quilting processing, this resin can improve the sewing speed when using 4 cotton. Although any type of resin may be used, acrylic ester resins are preferred in terms of wash resistance, processability, and durability.

Next, the present invention will be explained using the drawings.

FIG. 1 is an example of the stuffing material 1 of the present invention viewed from the side where the filling material A is placed in the side fabric and quilted. 2 shows a quilting row in which the batting body and the side fabric are integrated. 6
indicates a peripheral portion where batting bodies A and B covered with side fabric are integrated. 4 shows a quilting row in which batting bodies A and B are integrated in the central part. It is preferable that the surface shown in FIG. 1 should face outward as a filler. In other words, it is better to use a table.

FIG. 2 shows the batting body B viewed from the direction of the side fabric. The numbers are the same as above. This surface is preferably the side that comes into contact with the heat insulating body or the human body.

Fig. 3 is an enlarged view of a part of the cross section of the o-o' plane in Fig. 1, where 5 indicates the layer of batting A (actual fibers are not shown), and 6 indicates the batting. The layers of body B are shown. 7.8 is a nonwoven fabric used as the lining of the batting bodies A and B, respectively, and does not appear on the outside when integrated as a stuffing body. 9 and 10 are the side fabrics that are the outer fabric, and 1st surface 9 mainly appears on the outer surface, and 6
The surface 10 is the side material which becomes the back surface. 2 and 4 indicate the above-mentioned quilting threads. The overall thickness is 2
~5an is practical.

Figure 4 shows the kotatsu 12. This figure shows how to use it as a kotatsu futon, and the other parts fixed by the quilted part 4 in the center are slightly separated, which is expected to have the effect of forming a space 11.

Next, the effects of the present invention will be explained. The points stated in the objectives,
In addition to the effects described in the explanation of the structure, the filling object of the present invention is very small and compact when folded and stored when not in use.

Does not take up storage space. This is because the thickness of a kotatsu futon, which is about 5-inch thick, can be reduced to about 25-inch thick if it is intended to have the same level of heat retention as a conventional filling made only of web cotton. Furthermore, when quilting cotton is layered, the creases do not bend at an acute angle when folded, making it impossible to store the product compactly.

This will be explained below using examples.

Example 1 Table 1 shows futon production standards and thermal flow resistance (1/K)
This figure shows the measurement results.

As can be seen from this result, the two-layer structure sample has l/K
It has a high level of heat retention and is well used. Moreover, compared to sample 6.4, which has a conventional simple two-layer structure,
The product of the present invention has the effect of improving heat retention ability by about 10%.

The thickness of the fiber was also important; the thinner the fiber, the more effective it was.

Example 2 Sample 1-1 with the same specifications as Sample 1 shown in Example 1 but with different shrinkage numbers of polyester raw cotton and the specifications shown in Table 2 was prepared.
1-2.1-5.1-4 was prepared and tested for wrinkle removal and morphological changes due to washing. The results are shown in Table 2. Samples 1-1 to 4 were favorable, but 1-1
-1 was unfavorable because it had a low fiber shrinkage number, so there was a lot of cotton shedding, and it also caused cotton to break during washing.

Example 3 Inventive product sample 7 and conventional product shown in Table 3.

Namely, sample 8 is a web laminated cotton product.

We created a futon for a kotatsu, set it up with an actual kotatsu, and measured the power consumption. The kotatsu futon used at this time was a combination of polyester cotton and V-tongue, the outside temperature was 10℃ x 5 (1% Ru), and the temperature inside the kotatsu could be constantly controlled at 55℃.The result was is as shown in Table 6.

The power consumption of the product of the present invention was significantly lower.
