[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth mainly used for automobile interior materials, interior decoration materials, furniture, clothing and the like, and more particularly, a cloth in which synthetic resin pipes are continuously inserted into a knitted or woven fabric. The present invention relates to a production method thereof and a laminate using the cloth as a base cloth.

2. Description of the Related Art Conventionally, knitted and woven fabrics are generally made of yarn, and fabrics in which synthetic resin pipes have been inserted have never been seen before, and the same applies to laminated materials. Conventionally, insertion knitting for knitting an insertion yarn into a ground knit such as a flat knitted fabric or a rib knitted fabric is known, but in a circular knitting machine, a gap between a dial and a cylinder is as narrow as at most about 5 mm, and a pipe is knitted during knitting. It was difficult to insert.

[0003] In recent years, the problems of increasing carbon dioxide gas and global warming have come to the fore, and at the same time, a temperature control seat (Climate Controlled Seat), commonly called CCS, has been used for automobile seats, and cooled air has been introduced into the seats. There is a sheet that is fed in and jetted to the surface of the sheet to partially cool a driver or the like. According to this method, compared to the conventional method of raising and lowering the temperature of the entire room, it is said that there is an energy saving effect by suppressing the use frequency of cooling and heating, and development of such a partial temperature control is demanded. .

[0004]

SUMMARY OF THE INVENTION The present invention relates to a novel fabric which is completely different from a conventional knitted fabric, that is, a fabric in which a synthetic resin pipe is inserted into a conventional knitted fabric by a knitting machine or a loom. It is intended to provide a manufacturing method and a laminated material using this fabric as a base fabric. In particular, the conventional circular knitting machine was improved to make it possible to insert and knit a pipe by increasing the distance between the dial and the cylinder. In addition, as an application of the cloth into which the pipe is inserted or a laminate thereof, one having a temperature control function is added as a partial temperature control device, such as an automobile seat, a theater seat, bedding, flooring, clothing, and the like. It is another object of the present invention to provide a widely usable material such as a cushioning material in which air is sealed in a pipe and a fire protection material in which a fire extinguishing agent is sealed, and a method of manufacturing the same.
