Description

The present invention relates to a cloth as a middle material for bedding and clothing. More specifically, the present invention relates to a cloth suitable as a middle material for bedding and clothing made of highly elastic non-woven cotton.

Conventionally, down and cotton have been used as the middle material for bedding and winter clothing, but there are inconveniences such as being bulky, heavy, warmer than necessary, and not becoming smaller when carrying, storing, and storing. ..

On the other hand, there is an invention of batting using a net-like non-woven fabric as a support material (Patent Document 1). Further, there is an invention relating to a composite elastic sheet composed of a net-like structure and a non-woven fiber web and having high elasticity in at least one direction (Patent Document 2).

If feathers or cotton is used as the middle material of bedding or clothing, the feathers may pop out from the side area, or twist or bias in the bedding or clothing. In order to reduce such defects, Patent Document 1 describes an invention of a batting in which a net-like non-woven fabric is used as a support material and synthetic cotton is laminated and entangled therewith, but the material has elasticity. is not it.

Further, Patent Document 2 describes a sheet made of elastic non-woven fiber, but since it is used for diapers and disposable underwear, it does not have heat retention and bulkiness, and is washable and quick-drying. Is not considered.

If the non-woven cotton is thickened in order to obtain heat retention and bulkiness, it becomes heavy as a whole, and it is not easy to use because it becomes bulky during storage. In addition, it is difficult to wash the clothes in a washing machine, and it is not easy to dry them, which further increases the cost.

Therefore, in the present invention, the drawbacks of the prior art are improved, structurally bulky is obtained, and by laminating an elastic fabric, an air layer is secured between the non-woven cotton and the heat-retaining property and the elasticity. The purpose is to provide the middle material of bedding and clothing with.

In order to solve the above problem, in claim 1 of the present application, a non-woven cotton is quilted with an elastic thread to give elasticity in both the vertical and horizontal directions to obtain a bulky middle material. In claim 2, the non-woven cotton is laminated with a stretchable fabric while applying tension, and the fabric is partially joined.

In claim 3, the basis weight of the stretchable fabric to be laminated is 100 g / m2 or less, in claim 4, the basis weight of the sheet-shaped non-woven cotton used is 20 g / m2 to 300 g / m2, and in claim 5, the weight of the middle material fabric is set. The elongation rate is set to 120% to 250%. Further, in claim 6, in order to impart breathability and lightness, the fabric to be laminated is made into a mesh shape.

Further, in claim 7, the middle material cloth is provided with a bulkiness of 3 to 10 times the total thickness of the cloth to be used.

Since the sheet-shaped non-woven cotton has elasticity, it is bulky, and it becomes a middle material cloth having a soft texture with cushioning properties and high heat retention.

A bulky medium-sized fabric with excellent elasticity and heat retention that uses sheet-shaped non-woven cotton as a support material because it is laminated with sheet-shaped non-woven cotton while applying tension to the stretchable fabric and partially joined. Is obtained.

Elasticity is imparted to the sheet-like non-woven cotton having a retaining formation, and not only the surface becomes uneven and bulky, but also a space is formed between the laminated fabric and the air layer, and this air layer is used as a heat insulating layer or a heat insulating layer. Functions as.

Since the sheet-shaped non-woven cotton has some degree of retention as a support material, a soft and ultra-thin fabric can be used as a side material, and the fit is good. In particular, the mesh fabric is excellent in lightness and breathability.

It has a three-dimensional surface and is excellent in design, and because it has stretchability and adhesion to the body, it has high followability to body movements such as turning over, and it also fits the body as a middle material for clothing. Have.

Since the lightness and elasticity can be freely adjusted by adjusting the sheet-like non-woven cotton, the number of laminated side fabrics, the roughness of the side fabrics, the knitting yarn, etc., the range of application to bedding and clothing used is wide.

Since the sheet-shaped non-woven cotton is laminated with the side fabric as a support material, it has the effect of improving the shape retention, improving the washing resistance, reinforcing the non-woven cotton, and preventing the cotton from breaking.

Although it has a three-dimensional structure as a multi-layer structure, the air layer provides heat retention and bulkiness because it contains an air layer, while it becomes compact because the air layer is not pressed when folded and is small when carried. It is convenient to handle because it is not bulky when folded and stored.

The same, the back side photograph of the middle material cloth. The same, side photograph of the middle material cloth. Sheet-shaped non-woven fabric A medium-sized fabric made by laminating elastic fabrics on both sides of cotton. Same as the side photo. A partially enlarged explanatory view of the middle material fabric.

The middle material fabric according to claim 1 is a non-woven fabric in which the entire non-woven fabric is quilted by using a machine capable of knitting elastic threads into a sheet-shaped non-woven fabric cotton.

Specifically, elastic threads are inserted or knitted into the sheet-shaped non-woven fabric using a warp knitting machine capable of knitting the fabric into the non-woven fabric. The elasticity given can be adjusted according to the direction of the quilt (vertical, horizontal, or both). Further, by setting the quilt width to 2 cm or more, unevenness is generated in the height direction, and a soft and bulky middle material cloth can be obtained.

However, a middle material made of only sheet-shaped non-woven cotton may cause problems such as cotton breakage, cotton wiping, and the thread used for the quilt coming off.

Therefore, in claim 2, a fabric having shrinkage is laminated as a side fabric on one side or both sides of the sheet-shaped non-woven cotton, and the sheet-like non-woven cotton and the side fabric are partially laminated while applying tension to the shrinkable fabric. To obtain a bulky non-woven fabric to which strong shrinkage is imparted as a whole. The middle material fabric, which is the laminated body thus obtained, has irregularities in the thickness direction, and they form an air layer containing air.

As the joining method, quilt sewing, heat welding, ultrasonic welding and the like can be considered, but the joining method is not limited to these methods.

FIG. 1 is a perspective view of a middle material fabric obtained by laminating and partially joining a sheet-shaped non-woven cotton on the side fabric according to claim 2, and FIG. 2 is an enlarged perspective view. .. The middle material cloth 1 is composed of a sheet-shaped non-woven fabric cotton 2 and a mesh-shaped stretchable cloth 3. The stretchable fabric 3 is preferably thin and light, and is a so-called mesh-like fabric in which the mesh of 30 g / m2 to 40 g / m2 is coarsely knitted, and is knitted using elastic threads 4 so as to expand and contract in the width direction. ing. The mesh-shaped stretchable fabric 3 is arranged on one side of the sheet-shaped non-woven fabric cotton 2, and the sheet-shaped non-woven fabric cotton 2 and the mesh-shaped stretchable fabric 3 are joined while applying tension to the fabric 3. Here, the elastic threads are sewn in a wavy shape at intervals of 10 cm or more (a in FIG. 7). Further, the vertical swing width (b in FIG. 7) of the wavy stitch 5 is 5 cm or more, and the horizontal swing width (c in FIG. 7) is 10 cm or more.

By laminating the mesh-like stretchable fabric as the side material, the middle material fabric with elasticity is completed as a whole, and since the side material is mesh-like, a light and highly breathable middle material cloth is obtained. You can do it.

FIG. 3 is a photograph of this middle material fabric as viewed from the back surface. It can be confirmed that the non-woven cotton is greatly shrunk. Further, FIG. 4 is a photograph showing the state in which the middle material cloth 1 is viewed from the lateral direction. The thickness of the sheet-shaped non-woven fabric cotton 2 used here is about 5 mm, and the thickness of the mesh-shaped stretchable fabric 3 is about 1 mm. If the two fabrics 2 and 3 are simply laminated, the thickness will be about 6 mm, but since the overall shrinkage is large, the obtained middle material fabric 3 has large irregularities on the surface. The thickness is 3.5 cm at the highest point.

Further, a large space is created between the two fabrics, which becomes an air layer and imparts heat retention and heat insulation to the middle material fabric 3. On the other hand, it is soft to the touch, has excellent cushioning properties, and is lightweight. In addition, since the thickness of the fabric used does not make it bulky, it can be folded into a small size, which is convenient for carrying and storing.

Further, the non-woven cotton is reinforced by sewing the side material to the sheet-shaped non-woven cotton.

As the basis weight of the sheet-shaped non-woven cotton used in the present application, if it exceeds 300 g / m2, the thickness becomes too large by itself, so that it is not suitable as a material for hanging bedding or clothing. On the other hand, if the weight is 20 g / m2 or less, the cushioning property and heat retention property of the middle material cannot be maintained. Therefore, the basis weight of the sheet-shaped non-woven cotton is preferably selected from 20 g / m2 to 300 g / m2.

The above-mentioned medium-sized fabric is a sheet-like non-woven cotton in which the elastic fabric is arranged on only one side, but the elastic fabric is arranged on both sides while applying tension, and the three-layered fabric is partially joined to the inside. It is also possible to form a material fabric. Since both sides of the sheet-shaped non-woven cotton are covered with the side material, the shape of the middle material is further stabilized, and the fabric is less likely to be cut or blown out. Further, since an air layer is formed between the respective fabrics, it is softer and bulkier, and the heat retention is improved.

A sheet-shaped non-woven cotton may be used as a support layer and side fabrics may be arranged on one side, or a sheet-shaped non-woven cotton may be sandwiched between side fabrics to form a three-layer structure, or this may be repeated to form a five-layer structure or the like. It is possible. In other words, the thickness and heat retention of the finished product can be controlled by selecting the number of layers to be laminated and the fabric to be used for the side fabric, and the optimum middle material fabric can be manufactured according to the usage of bedding and clothing according to the season. Can be done.

In addition, there are no restrictions on the thread material and knitting method of the fabric used as the side fabric, and by applying various processing treatments (waterproof, water repellent, antibacterial deodorant, tickproof, antistatic) to the finished middle material fabric. Furthermore, functionality can be added according to the intended use.

Further, it is not necessary that the types of side areas are the same, and it is of course possible that the structure is made by using a plurality of types, but it is desirable that the basis weight of the side areas is 100 g / m2 or less. Although it has a multi-layer structure, it is desirable that the finished product is 400 g / m2 or less.

As another embodiment of the present invention, a middle material cloth made of a thin mesh cloth having a more crisp feeling as a side material is formed. For the side fabric, a warp knitted fabric is used, which is formed by inserting elastic yarns into a net-like base fabric knitted only with multifilament yarns of chemical fibers of 15 to 300 denier and expanding and contracting in a bellows shape in the lateral direction. Further, it is desirable that the knitting density of this warp knitted fabric is from 1 cm 5 stitch course to 20 stitch course.

The middle material cloth shown in FIG. 5 is formed by arranging the above-mentioned warp knitted fabric having elasticity on both sides of the sheet-shaped non-woven cotton and partially joining them. It is shrunk to the extent that large irregularities are formed on the surface, and it has bulkiness as shown in FIG. 6 in the height direction.

Although the present invention has been described using the above embodiments, various design changes can be made without departing from the spirit of the invention.

The middle material cloth made of sheet-shaped non-woven cotton according to the present invention can be widely used as a middle material for bedding, particularly a quilt, as well as for clothing or as a middle material for pillows, cushions and the like.
