Method for stiffening headgear

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...

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.

[0010] The secondary object of the invention is to provide a method for stiffening a headgear, in which the linings of the headgear can be stiffened without the application of a heated resin, thus avoiding the occurrence of any poisoned material such as HCHO and allowing the user to wear the headgear more safely.

[0011] A further object of the invention is to provide a method for manufacturing a headgear which has better ventilation.

[0013] To obtain the above objects, the invention utilizes the knitted thermo polyester linings made of threads consisting of fine and soft filaments extracted from thermo polyester pellets to sew with the ready-cut fabrics, and then combined with the peak and the sweatband to form a headgear. Subsequently, the headgear together with linings is heated by a mold, thereby shaping an upstanding and neat headgear.

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.
