Description

[Detailed explanation of the idea]

[Purpose of the invention] (Field of industrial application) The present invention relates to a heat-retaining fabric that is interposed between the outer fabric and the lining fabric of various types of clothing that require heat-retaining properties. (Prior Art) For example, winter sportswear such as ski wear pursues scientific rationality in addition to its fashionability, and technological innovation is progressing at a remarkable pace. The functions pursued are those of the outer material and lining of clothing, namely flexibility, fit, reduction of resistance to airflow, heat retention, breathability, prevention of moisture permeation from the outside, and moisture diffusion from the inside. , as well as weight reduction. (Problems to be Solved by the Invention) Outer materials and lining materials developed to provide various functions in addition to the above-mentioned fashionability are naturally expensive. However, the main premise of product development is how low the price can be provided, but there is an inverse relationship between improved functionality and lower prices, and most problems have been solved for the outer material and lining material. It is something that cannot be done. This invention departs from the above-mentioned solutions for the outer material and lining, and reduces the weight of the inner fabric sandwiched between the outer and lining materials.
The object of the present invention is to obtain a fabric which is improved in breathability, non-hygroscopicity, cutting and sewing properties, and is made inexpensive by completely ignoring fashionability. [Structure of the invention] (Means for solving the problems) The heat-retaining fabric according to the invention is made of flat yarn or monofilament, the inner layer of which is made of a high melting point thermoplastic synthetic resin, and the outer layer made of a low melting point thermoplastic synthetic resin. The composite yarns are woven by arranging them in the warp or warp, and the outer layer of the composite yarns in the woven base fabric is melted to fuse the warp and warp yarns to each other, and the base fabric A metal vapor-deposited layer such as aluminum is attached to both or one side. (Example) The present invention will be specifically explained using an example in which a composite yarn made of flat yarn is used. As shown in FIG. 3, the composite fiber 1 made of flat yarn has an inner layer 2 molded from high-density polyethylene resin with a melting point of 133°C, and two outer layers 3 laminated on both the front and back surfaces of the inner layer 2.
No. 4 has a melting point of 104°C and is molded from ethylene acrylic acid copolymer resin (modified polyolefin) that has good adhesion to metals, and is 100 denier with a flat yarn width of 0.85 mm and a thickness of 14 μm. The thickness of inner layer 2 is 10μ, and the thickness of outer layers 3 and 4 is 2μ.
And so. The above-mentioned composite yarn 1 is formed by a flat yarn extrusion device shown in FIGS. 4 and 5, and an inner layer resin extruder 7
The outer layer resin extruder 10 is connected to a pair of inlets 8 and 9 provided on the side, and the inner layer resin channel 11 and the outer layer resin channel 12 and 13 are connected to the outlet port 14 in the die 5. It is obtained by drawing the flat yarn sent out from the outlet 14 of this device and subjecting it to heat treatment. The composite threads 1 are arranged in warp and warp directions and woven in a plain weave structure on a loom 15, as shown in FIG. 6, at a rate of 30 threads/inch in both warp and warp directions. Incidentally, it is not necessary to use the composite yarn 1 for both the warp and the weft, and it is also possible to use the composite yarn 1 only for the weft and weave a 100-denier flat yarn made of a single layer of polyethylene resin in the warp. By passing the base fabric 16 woven in this way between a heating roll 17 and a pressure roll 18 shown in FIG. 6, the outer layer resin of the composite yarn 1 is melted, and the composite yarns 1 in warp and weft are thermally fused together. . Similarly, in the case of a base fabric with a weft of composite yarn 1 and a warp of single-layer flat yarn,
The warp and warp yarns are fused to each other by the molten resin in the outer layer. Note that the treated base fabric 16 is rolled into a roll 1.
Caught up in 9. Furthermore, as shown in FIGS. 1 and 2, a metal vapor deposition layer 20 made of aluminum alloy is attached to one side of the base fabric 16, and the layer 20 can be applied to both sides of the base fabric 16. good. In addition, when metal is vapor-deposited, there is an anchor coating method in which the surface of the base fabric 16 is subjected to corona discharge treatment or an adhesive such as polyethyleneimine is applied, but the anchor coating method is expensive and also In the case of corona discharge treatment, strong adhesion cannot be obtained by using a general polyolefin resin as the outer layer resin, but as mentioned above, a modified polyolefin resin made of ethylene acrylic acid copolymer can strengthen the metal vapor deposited layer 20. It can be glued. Therefore, the various functions of the fabric, which was woven by arranging composite filaments made of flat yarns in the warp and warp, and heat-sealed and attached a metal vapor deposited layer of aluminum alloy, were as follows.

[Effect of idea]

The heat-retaining fabric according to the present invention has a soft feel, is extremely light, has good breathability, and exhibits sufficient heat-retaining ability due to the metal vapor deposited layer. Furthermore, since the threads constituting the base fabric are fused to each other, there is no fear that the threads will fray even when cut, and the fabric can be easily sewn.
