LOOSELY WOVEN SHEET FOR AGRICULTURE, FORESTRY, CIVIL ENGINEERING AND CONSTRUCTION USE CAPABLE OF HIGH-FREQUENCY SEAM-WELDING, ITS WELDING PART AND USAGE THEREOF

Document Type and Number:

Japanese Patent JPS5828326

Kind Code:

A

Abstract:

PURPOSE: To rigidly and efficiently seam-weld the titled sheets adjoining each other for agriculture, forestry, civil engineering and construction by a high- frequency radio wave with a thin piece having high frequency fusible bondability being interposed thereon.

CONSTITUTION: Yarns or strings which have no high-frequency fusible bondability are arranged as warp and weft and are woven, thereby forming a sheet being relatively loose in meshwise. This sheet is immersed in polymer solution having high-frequency fusible bondability, and is then dried, thereby preparing a high frequency seamable sheet. Said sheet 11 and an adjoining sheet 12 of the same type are seamed by a high frequency radio wave on the upper surface of a thin fabric piece 10 having high frequency fusible bondability. In this manner, a product have large strength at the seamed part.
