Stretchable sweatband for a cap

Abstract

A sweatband used for headwear that is woven of 100% combustible synthetic yarn without any polyurethane. The sweatband provides excellent sweat absorbing capability and exhibits good elasticity through the structure of the textile without imposing undue pressure on the wearer so that the sweatband may be worn comfortably for a long period of time. The yarn used to produce the sweatband is passed through a bulky process, being shrunk through a low temperature short-term combustion method and dry heat treatment process after weaving. The sweatband preferably has a unitary, single ply construction that is planar and does not twist in the absence of elongating force.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is related to the field of headwear and, more particularly, to an improved stretchable sweatband woven as one unit body and having a highly efficient sweat-absorbing capability. [0003] 2. Description of the Related Art [0004] Caps of the baseball-style type generally include a crown main body, a visor portion that is secured to the forward edge of the crown and extends outwardly therefrom, a headband or sweatband attached to the lower part of the inside of the crown, and a size controller attached to an underside of the rear of the cap. Alternatively, cap sweatbands have been constructed that include an elastic band made of fabric which includes spandex yarn, giving the sweatband size flexibility while eliminating the size controller. [0005] It has been found, however, that caps relying on spandex sweatbands for sizing exert pressure against the wearer's head which can become uncomfortable afte...

AI Technical Summary

Benefits of technology

[0007] In view of the foregoing, one object of the present invention is to provide headwear with a sweatband that does not exert undue pressure on the head when worn.

[0008] Another object of the present invention is to provide a cap having excellent sweat-absorbing capability.

[0010] Yet another object of the present invention is to provide a sweatband that affords elasticity through the structure of the textile, the yarn from which the sweatband is made being subjected to a bulking and shrinking process which leaves the sweatband flat and suitable for use with headwear.

[0011] A still further object of the present invention is to provide a sweatband of sufficient elasticity to provide variable sizing to a cap without the need for a separate size controller.

[0013] In accordance with these and other objects, the present invention is directed to a sweatband mainly used for headwear and woven by 100% nylon combustible synthetic yarn to produce a unitary body without additional stitch work. After weaving the nylon yarn, the sweatband is passed through a bulky process and then processed to be shrunk through a low temperature short-term combustion method, followed by drying through a heat treatment process to produce a file-shaped, planar length of elastic material that does not twist in the middle when relaxed. Having no polyurethane, the sweatband demonstrates elasticity as a whole due to the structure of the textile. The circumferential stretch direction of the sweatband also provides excellent sweat absorption capability and a wide range of automatic size adjustment may be obtained without imposing undue elastic pressure on the wearer.

Problems solved by technology

It has been found, however, that caps relying on spandex sweatbands for sizing exert pressure against the wearer's head which can become uncomfortable after the cap is worn for an extended period of time.
