Abstract

PURPOSE:To make skin touch agreeable and improve a drape characteristic by bonding two sheets of warp knitted fabric spot by spot and fixing two sides being perpendicular to a knitted direction, in which elasticity is large with a linearly applied adhesive material. CONSTITUTION:A heating wire 4 is mounted in a mounting channel made by bonding an upper side Meyer blanket 1 and a lower side Meyer blanket 2 by means of a humidity setting hot melt adhesive material 3 applied to the total area thereof spot by spot and further both upper and lower sides being perpendicular to a knitted hot met direction are bonded with the linearly applied humidity setting hot met adhesive material 3, thereafter the four sides are wrapped with hem cloth 5 and sewed up with thread 6 by a sewing machine. That is, as the mounting channel is bonded with the spotted adhesive material 3, the blanket is easy to be bent and pliant, and further as the Meyer blankets 1 and 2 are free to be stretched and shrunken, no wrinkle is generated during a bonding process, and as the adhesive material 3 is included in the hem cloth 5, no foreign matter feeling is given to a user. Thereby the skin touch becomes agreeable and the drape characteristic is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a heating cloth for electric heating appliances made of cloth, such as electric blankets, electric lap blankets, and electric carpets.

(Prior art) Conventional heat generating fabrics of this type, for example, are made by weaving 72 pieces of cloth and simultaneously weaving binding threads between them at predetermined intervals, while integrating the two pieces of cloth. A heating wire is inserted into the mounting structure, and the heating edge is attached to the width of the mounting after being brushed.

Alternatively, heating wires are temporarily nailed between two pieces of cloth in a predetermined pattern, and then the entire surface is adhered with a water-soluble adhesive or a bolt-melt adhesive.

(Problems to be Solved by the Invention) However, in the above configuration, for example, in a double weave blanket with binding yarn, due to the structure of the loom, it is a plain weave.

There was a problem in that it was limited to twill fabrics.

In addition, with fully adhesive blankets, the two blankets are stretched against each other, making them stiff and lacking in drapability.Furthermore, since the heating wires are also fixed together, external forces applied to the blanket are transmitted to the heating wires, making them easy to break. It was also thick.

In addition, when bonding red knitted fabrics such as boa fabrics and Mayer knitted fabrics to heating wires, the expansion and contraction rates of the bonded and non-bonded areas are different, so II! - There was also the problem that after processing, the outer edge of the fabric stretched into a fan shape in a direction perpendicular to the knitting direction of the fabric, impairing the outer line.

The present invention solves the above-mentioned problems, and can be used with boa fabrics, Meyer knitted blankets, etc., which have excellent appearance and skin-friendly cilia. To provide a heat-generating cloth button that does not impair its properties and appearance.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a moisture-curing hot-melt film that is dotted on the entire surface of two warp-knitted fabrics.
Glue with adhesive (form a mounting structure between them and attach the heating wire), and then apply the above moisture-curing hot melt adhesive in a linear form on both sides perpendicular to the knitting direction. After coating and adhering, the edge cloth is attached.

(Function) With the above configuration, the two warp knitted fabrics are bonded in dots, so they do not become stiff. In addition, since both sides in the direction perpendicular to the knitting direction, which have high elasticity, are fixed with adhesive applied in a straight line, stretching can be prevented even if external force from the sewing machine is applied during edge processing.

(Example) An example of the present invention will be described with reference to FIGS.

FIG. 1 is a partially cutaway plan view of a heating cloth using a Mayer blanket according to the present invention, and FIG. 22 is an enlarged cross-sectional view of a main part showing a side perpendicular to the knitting direction.

Fig. 1 shows 19 pieces of heat-generating cloth according to the present invention, -1 side Meyer blanket] and + side Meyer blanket 2 applied in dots on the entire surface. A heat-generating wire 4 is attached to the mounting structure glued with adhesive 3, and the upper and lower sides perpendicular to the knitting direction are coated with moisture-curing hot melt adhesive 3 as described above.
After applying and adhering in a line, the four sides are wrapped with hem cloth 5 and sewn under thread 6 using a sewing machine, as shown in FIG.

In this example, the adhesive 3 is 5UPER manufactured by Bostik.
It was applied using GR1P 2000 (trade name) at an applicator temperature of 110°C. Note that the coating value of 5 is 0.02 to 0.03 g/point for dotted areas and 1 to 2 g/point for linear areas.
g/m, left it for about 30 seconds, and then glued it with light pressure at room temperature.

In the example, the mounting structure is bonded with dotted adhesive, so the blanket is easy to bend and is flexible. Since the blanket can be expanded and contracted, wrinkles do not occur during the bonding process, and stress is not concentrated on the adhesive 3 even if the blanket is expanded or contracted by external force during use, making it durable.

Since the outer edge of the fabric, which is perpendicular to the knitting direction, is fixed with adhesive, when sewing the hem fabric 5 with a sewing machine, the fan-shaped deformation as shown by the two-dot chain line in Fig. 1 may occur. Does not occur.

In addition, when the upper and lower fabrics are long pieces of fabric and adhesive processing is performed continuously, the outer edges can be fixed before cutting the fabric in the width direction, so the tension applied to the fabric when sewing the hem fabric can cause The fan-shaped deformation shown by the two-dot chain line does not occur5.Furthermore, the adhesive has elastomer-like flexibility even after solidifying, and is contained within the hem fabric 5. It does not give the user the feeling of a foreign body, and since the entire surface is not glued, it is soft and feels good when used.

(Effects of the Invention) As explained above, the invention utilizes warp-knitted fabrics such as boa fabrics and Mayer knitted blanket fabrics that have excellent external lines and cilia that are gentle on the skin. An excellent heat generating cloth can be obtained.

Furthermore, a heat-generating cloth is obtained in which fan-shaped deformation of the outer edge of the fabric does not occur during sewing, and no deformation after cutting due to differences in fabric tension and wire drawing rate occurs even when continuous processing is performed from a long fabric.
