Unlock Super Thin Shoe Insole Material: Antibacterial and Deodorizing Diatomite Non-woven Fabric


   With the accelerated pace of modern life, people's attention to foot health has significantly increased. Especially in sports and outdoor settings, odors and bacterial growth become pain points for user experience. The emergence of antibacterial and deodorizing diatomite non-woven fabric material combines antibacterial and deodorizing functions in an ultra-thin form, providing a new solution for the insole industry.

Material Introduction

Antibacterial and deodorizing diatomite non-woven fabric is a new type of insole material made by composite process of diatomite composite and non-woven fabric. Non-woven fabric is a moisture-absorbing and breathable water jet process non-woven fabric. The main material of the composite is diatomite, which is a lightweight, porous structure, and has strong adsorption properties. The fusion of high moisture absorption and moisture locking materials has the characteristics of being less prone to saturation, mainly including the following aspects.

1. Moisture absorption and locking properties: Multiple materials are composite to give it gradient moisture absorption ability and high moisture content, with a moisture content of 400% of the mass. It can lock in moisture and store it in the diatomite layer, keeping the surface dry.

2. Moisture regulation and removal: The porous structure of diatomites has the ability to regulate and remove moisture, automatically absorbing or releasing water according to the humidity of the environment, avoiding excessive humidity or dryness, and achieving relative humidity balance. When the environmental humidity is below 40% RH, it will continue to release moisture and naturally regenerate.

3. Adsorption and deodorization ability: The porous structure of diatomites has strong adsorption properties and can effectively adsorb odors. Thanks to the high moisture content and low saturation of composite materials, they also have the ability to adsorb and remove odors in humid environments.

Principle of Antibacterial and Deodorizing

1. Antibacterial mechanism: The antibacterial and deodorizing diatomite non-woven fabric adopts composite slow-release antibacterial technology, which releases chlorine dioxide for sterilization and disinfection. Its high-efficiency and broad-spectrum bactericidal ability can effectively kill fungi, prevent fungal infection and reproduction, and has an antibacterial rate of 99%.

2. Deodorization principle: It mainly eliminates odors through the physical adsorption of diatomites and the decomposition of chlorine dioxide active particles. The fine porous structure of diatomites can adsorb odors inside shoes. The high moisture content of the fusion of strong sweat-absorbing materials ensures that diatomites still have the ability to adsorb odors in humid environments. Additional chlorine dioxide releases gas-phase active particles to decompose odors, which can eliminate 82.6% of odors. Effectively prevent the generation of odors.

The Advantages of Ultra-thin Design

The thickness of antibacterial and deodorizing diatomite non-woven fabric is 0.7mm, which provides a prerequisite guarantee for the ultra-thin design of insoles and brings many benefits:

1. Wide adaptability: Ultra-thin insoles can easily adapt to various shoe types, especially shallow shoes that require high interior space, without adding extra thickness, ensuring the appearance and comfort of the shoes.

2. High comfort: The ultra-thin design reduces the pressure of the insole on the feet, allowing the feet to move more freely inside the shoe and improving the comfort of wearing.

3. Good breathability: Ultra-thin materials can better promote the circulation of air inside the shoes, reduce foot sweating and moisture, and keep the inside of the shoes dry. 

Application Scenarios

Antibacterial and deodorizing diatomite non-woven insoles are suitable for various scenarios and shoe types:

1. Sports shoes: During exercise, the feet are prone to sweating. Moisture absorbing materials can effectively absorb sweat from the feet and lock in the diatom layer, keeping the inside of the shoes dry. The antibacterial and deodorizing function can effectively reduce odors and enhance the sports experience.

2. Casual shoes: When worn daily, ultra-thin insoles can provide a comfortable foot feel while reducing odors and keeping feet fresh.

3. Work shoes: For personnel who wear work shoes for a long time, the antibacterial and deodorizing function can relieve foot fatigue and maintain a healthy shoe environment.

Environmental Protection and Health

The material of antibacterial and deodorizing diatomite non-woven fabric is a natural diatomite composite, which is non-toxic, harmless, and free of volatile harmful substances. It will not cause irritation to the skin and is suitable for use by various groups of people.

Future Prospects

As people's attention to health and environmental protection continues to increase. The market prospect of antibacterial and deodorizing diatomite non-woven fabric is broad. In the future, this material is expected to be further optimized by combining more functional features such as intelligent temperature control and massage, bringing consumers a better user experience. At the same time, with the continuous advancement of technology, costs will also be further reduced, making it more widely applicable to various insole products.

   In summary, antibacterial and deodorizing diatomite non-woven fabric, as a new type of ultra-thin insole material, has been recognized and widely accepted by the market due to its excellent sweat absorption, moisture retention, antibacterial and deodorizing properties, ultra-thin design, and environmentally friendly and healthy characteristics.
