Benefits of technology

[0009] The primary purpose of the present invention is to provide a method for stiffening a headgear which can have an upstanding and neat shape.

Problems solved by technology

However, there exists a disadvantage in the above-mentioned headgear process, i.e. heating the resin adhesive will generate HCHO which, being a colorless and easily melted irritating gas, is harmful to human body, since it can be absorbed by human through aspiratory system, and the solvent of HCHO, formalin, will be absorbed through digestive system.
HCHO is definitely harmful to human body, since it can enter human body to connect with amine of protein, and cause alteration of the protein, thereby disturbing the metabolism of cells and seriously destroying cell organization.
According to international reports, when formalin has a density exceeding 0.12 mg / m3, it will easily cause asthma in children.
In view of the above, headgears composed of heated resin might cause diseases to the users after long-term use.
In addition, infiltrating resin into the fabric will make the fabric unventilated, rendering the user feel hot and constantly sweat.

Embodiment Construction

[0024] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0025] As shown in FIGS. 3 to 5, in the process of the present invention, two ready-cut fabrics 20 are sewn together via a needle 30 and threads 31 to form a front piece 21 of a crown. While the threads 31 are thermo setting polyester threads made from fine and soft filaments extracted from thermo polyester pellets, the linings are in form of a soft material. After the linings 40 are sewn together with the front piece 21, they are further sewn with a peak 41 and a sweatband 41 to form a headgea...

Abstract

A method for stiffening a headgear utilizes knitted thermo polyester linings made of threads consisting of fine and soft filaments extracted from thermo polyester pellets to sew with ready-cut fabrics to form a headgear. Subsequently, the headgear is heated by a mold such that the fiber of the linings will be appropriately stiffened, thereby shaping an upstanding and neat headgear as desired.

Description

BACKGROUND OF THE INVENTION [0001] 1. Technical Field of the Invention [0002] The present invention relates to a method for stiffening a headgear, which is full of aesthetic feelings with a fixed shape. Besides, as the stiffened linings are processed without adding any harmful chemical, such as HCHO, the method of the invention is especially applicable to the manufacturing of headgears. [0003] 2. Description of the Prior Art [0004] A conventional headgear is basically composed of a crown and a hard peak. As the front side of the crown is the most apparent portion, whether or not the headgear is neat, upstanding and good looking depends on the expression of the front side of the crown. [0005] In the manufacturing of headgear of the prior art, in order to make the headgear look upstanding and neat, the crown is adhered with linings of various kinds. Since it is required that the adhered linings must have certain rigidity, resin is generally used as an adhesive in this respect. As show...
