Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quilted cloth having heat retention similar to that of a quilted material.

[0002]

2. Description of the Related Art Conventionally, as a cloth for bedding having a heat retaining property, there is a cloth made of a quilting material as a cloth which is relatively thin and light, and a cotton blanket as a cloth for bedding which is comfortable to touch and easy to wash. .

However, in order to make a quilted material, the batting is spread and sandwiched between two woven fabrics so as to spread over the entire woven fabric, and the woven fabric is laminated with the batting so that the batting does not move. Since it is necessary to sew a cloth in a lattice shape with a sewing machine, there is a problem that the manufacturing work becomes very complicated when making a quilting material having a large area used for bedding or a sofa cover.

Further, although the cotton blankets which are usually on the market have a good feel to the skin, when the bulkiness and the heat retaining property are to be obtained, it is necessary to increase the height of the raised hair and the raised density so that the weight becomes heavy. There is.

Therefore, the inventor of the present invention has one of the warp yarn and the weft yarn having a weaving yarn and a batting yarn, and the other weaving yarn and one weaving yarn have an upper design and a lower design. And weaving a double weave consisting of these parts, connecting the upper design and part of the lower design during weaving, and forming a woven material by interposing a batting thread between the upper design and the lower design. Then, the material was heated and shrunk to form a bag-shaped space between the upper tissue and the lower tissue, and a quilted cloth in which the batting thread was transformed into cotton was invented (Patent application 2000-
6374).

Although this quilted material is similar in appearance and texture to conventional quilted materials, it is easier to manufacture than conventional quilted materials, and it also has heat retention due to the formation of an air layer due to heat shrinkage of the batting thread. is doing.

[0007]

However, the quilted material described above forms a space between woven structures, and a cotton-like batting thread is interposed in this space to reduce the weight and bulkiness. Although heat retention is obtained, the bulkiness and heat retention are limited because the batting thread is interposed between the two weaving textures that are laminated one above the other.

Further, in the case where the upper and lower double weaves are used, it is necessary to considerably increase the weaving density of the woven weave, that is, the weave weave, in order to prevent the inner batting yarn from being seen from the front side. However, in the case of increasing the woven density, if a thick yarn is used, the flexibility becomes insufficient, and if a thin yarn is used in consideration of flexibility, the air permeability becomes insufficient.

The present invention has been made in view of the above problems, and is similar to a quilting material that can be easily manufactured, has excellent heat retention, and has bulkiness, breathability, and flexibility. It is intended to provide a quilted fabric.

[0010]

In order to achieve the above object, the present invention provides that at least one of a warp and a weft is formed of a weaving yarn and a batting yarn, and the other yarn is a weaving yarn and the above-mentioned one. The multiple weaving design in which three or more layers are laminated on the upper and lower sides by the weaving yarn of the above-mentioned yarn, and the filling yarn is interposed between the upper and lower weaving designs Is connected to each other at a predetermined position during weaving, and the batting thread is deformed into a cotton shape by heat shrinkage.

The yarn for batting is a sliver-like yarn before weaving and shrinking during weaving, and when heated at a predetermined temperature, shrinks in the fiber length direction and becomes cotton-like (fiber and fiber A yarn made of a material that changes to a state in which a large space is formed between them, and may be any of synthetic fibers, recycled fibers, natural fibers, etc., but synthetic fibers such as polyester are preferable.

Further, when acrylic fiber is used,
The texture after heat shrinkage becomes soft. In addition, since it becomes cotton-like by heat shrinkage, it is preferable to use one that is hardly twisted, and a filament made of synthetic fiber is preferable.

Since the quilted fabric of the present invention includes the batting yarn in the warp and weft when weaving the weaving structure, the multiple weaving is performed when weaving the multiple weaving with the looms such as the jacquard loom and the dobby loom. Since the yarn for batting can be interposed between the woven structures that are woven at the same time as the woven fabric, a quilted cloth can be easily formed.

Moreover, when connecting a plurality of laminated weaving textures, the batting thread can be fixed to the weaving texture by simultaneously connecting with the whole weaving texture.
Prevents large movements between weaves. As a result, even when the cloth is violently moved such as by washing, it is possible to maintain the state in which the batting thread is evenly spread over the entire quilted cloth.

Further, the quilted cloth of the present invention is
Since it is assumed that it is composed of a multi-woven structure of three or more layers, the number of layers is not limited to three and may be four or five. When the batting thread is interposed between the upper and lower woven structures, the batting thread may be interposed between all layers, or may be interposed between some layers. You may

For example, in the case of a three-layer weave design structure, a batting yarn may be interposed between the layers, or a batting yarn may be interposed either above or below the weaving design of the intermediate layer. You may do it.

When the batting yarns are interposed between all the layers of the weaving structure which are superposed in multiple layers, the bulkiness which is the volume of the quilted fabric can be increased by the thermal shrinkage of the batting yarns interposed between the layers. .

Moreover, the quilted fabric of the present invention is
Since it is composed of multiple weaving designs of three or more layers, the outermost weaving design is formed by thin threads, and the inner layer weaving design is made thicker than the outermost weaving design, and in between. In the case where the yarn for use is not interposed, it is possible to prevent the yarn for batting from being seen without increasing the weaving density of the outermost layer, and to impart flexibility to the innermost layer while providing flexibility to the innermost layer. A reinforcing effect for the entire fabric can be imparted.

The batting thread intervening in the space formed between the laminated weave designs may be partially retained in the weave design by using the weaving thread of the weave design. preferable.

The term "partially retaining" means that when weaving the weaving structure, a part of the batting yarn is woven and held by a weaving yarn of a warp or a weft that intersects the batting yarn.

As described above, by holding a part of the batting thread in the weaving texture with the thread constituting the weaving texture, the movement of the batting thread in the space can be prevented more favorably.

Further, the number of laminated layers of the multi-layer structure may be partially made different with the connecting woven portion as a boundary.

By making the number of laminated layers of the multi-layered structure different from each other with the connecting woven portion as a boundary, the thickness and texture of each part of the quilted cloth separated by the connecting woven portion can be changed, which is visually enjoyable.

Furthermore, it is preferable to make the heat shrinkage rate of the batting thread larger than that of the weaving thread.

By making the heat shrinkage rate of the batting thread larger than that of the weaving thread, the swelling effect of the batting thread can be enhanced and the bulkiness and heat retention can be further enhanced.
