HAT MANUFACTURING METHOD, HAT AND ELASTIC CORE MATERIAL

PROBLEM TO BE SOLVED: To provide a hat suitable for head protection, having high shock-absorbing property and producible at a low cost while satisfying the requirements for common hats comprising light weight, air permeability and washing easiness. SOLUTION: A three-dimensional knit fabric 10 is set between an upper mold 21 and a lower mold 22 and heated without applying pressure. The residual stress of a ground fabric and a connection yarn is released between the upper mold and the lower mold by application of heat to the three-dimensional knit fabric 10 and the fabric is deformed following the contour of the mold to a knit state before heat-setting. Accordingly, the thickness of the three-dimensional knit fabric constituting a hat 50 is equal to or thicker than that of the three-dimensional knit fabric before processing. Since the fabric is not hot-pressed, the hat has high compression recovery and high shock-absorbing property and is suitable for head protection. COPYRIGHT: (C)2007,JPO&INPIT
