Woven Hat and Method for Manufacturing Woven Hat by using Ultrasonic Sewing Technology without Sewing Thread

A method for manufacturing a woven hat by using an ultrasonic sewing technology without a sewing thread, comprising:

• Step 1:
• preparing a hard visor lining, and cutting the hard visor lining to obtain two cut center-front-panel pieces, two cut rear-panel pieces, and two cut visor pieces;
• Step 2:
• bonding the two cut center-front-panel pieces using an ultrasonic sewing machine, and then applying to a bonding seam a hot-pressing bonding technology of heat-seal adhesive tape to form an arc-shaped combined center-front panel;
• bonding the two cut rear-panel pieces using the ultrasonic sewing machine, and then applying to a bonding seam the hot-pressing bonding technology of heat-seal adhesive tape to form an arc-shaped combined rear panel;
• and then bonding two side edges of the combined rear panel to two side edges of the combined center-front panel respectively, and applying to bonding seams the hot-pressing bonding technology of heat-seal adhesive tape, so as to complete manufacturing of a hat crown;
• Step 3:
• bonding a cut visor piece to each of two surfaces of the hard visor lining by using a hot-melt-glue hot-pressing technology, to form a visor;
• and
• Step 4:
• bonding the hat crown and the visor by using the ultrasonic sewing machine, wherein a process of jointing between the visor and the hat crown is carried out by the hot-melt-glue hot-pressing technology.

A woven hat, comprising a hat crown and a visor, wherein the hat crown comprises a combined center-front panel and a combined rear panel;

• two side edges of the combined center-front panel are correspondingly bonded to and connected with two side edges of the combined rear panel to form the hat crown which is hood-shaped, and a bottom arc edge of the combined center-front panel and a bottom arc edge of the combined rear panel cooperate with each other to form a closed circle;
• the combined center-front panel is a spatial arc panel formed by bonding and connecting two cut center-front-panel pieces at a first bonding seam;
• and the combined rear panel is a spatial arc panel formed by bonding and connecting two cut rear-panel pieces at a second bonding seam;
• and
• a concave edge of the hat crown and the bottom arc edge of the combined center-front panel coincide with each other and are connected together.
