Insole

Abstract

The present invention relates to a insole which is mainly made by the following process: reeling off single thread filament from recycled materials such as PET bottle, PET plastic material, waste fabric, recycled yarn into fiber; intermingling plastic fiber with the above fiber of recycled material and then conducting needle punching to form air-permeable thick layer of nonwoven fabric having 3-10 mm thickness; adhering nonwoven fabric or cover layer made by general fabric onto the air-permeable thick layer of non-woven fabric; conducting heat forming and cutting into suitable size. In this manner, not only the insole made by recycled material possesses environment protection feature but also the air-permeable thick layer of nonwoven fabric, which is needle punched from fiber, has excellent air permeability and appropriate elastic effect. Therefore, users have snug feeling achieved by good air permeability and shock absorption so that it has better performance in its total application.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an insole, particularly to an insole having environment protection feature, excellent air permeability and appropriate elastic effect, which is made from recycled materials such as PET bottle, PET plastic material, waste fabric, recycled yarn. Therefore, users have snug feeling achieved by good air permeability and shock absorption so that it can provide better performance in its total application.[0003]2. Brief Description of the Prior Art[0004]People often wear shoes for safety and clean reasons so as to protect foot from abrasion or piercing by pebble or foreign object when walking on rough or hard ground and to keep clean with hygiene at foot. Shoes has been evolved from straw sandals, clogs etc. at early stage to shoes nowadays made by a variety of materials such as cloth shoes, leather shoes. As to the style and color, a variety of beautiful, magnificent and specialized shoes have ...

AI Technical Summary

Benefits of technology

[0008]The insole of the present invention is mainly made by the following process: reeling off single thread filament from recycled materials such as PET bottle, PET plastic material, waste fabric, yarn into fiber; intermingling plastic fiber with the above reeled-off fiber and then conducting needle punching to form air-permeable thick layer of nonwoven fabric having 3-10 mm thickness; adhering nonwoven fabric or cover layer made by general fabric on the air-permeable thick layer of non-woven fabric; conducting heat forming and cutting into suitable for ready use. In this manner, not only the insole made by recycled material possesses environment protection feature but also the air-permeable thick layer of nonwoven fabric needle-punched from fiber has excellent air permeability. Therefore, users have snug feeling achieved by good air permeability and shock absorption so that it has better performance in its total application.

Problems solved by technology

The above insole can achieve expected effectiveness of much more snugness when users wear shoes with the insole, but it is found in practical application that the insole, formed by conducting foam-molding on a resin incorporated with a foam material, usually has poor air permeability.

Users often feel muggy when wearing these insoles.

Furthermore, this insole made by foam material has no environment protection feature.

Thus, this insole still has got space for improvement.
