Shoe material anti-yellowing agent: the key to improving the durability of sports shoes

1. Introduction: Start with the “appearance crisis” of a pair of sneakers

In this era of face-looking, sneakers, as both fashion and functional items, have long become the standard equipment for young people’s wardrobe. Whether it is street fashion or sports fields, a pair of brand new sports shoes can always make people shine. However, over time, the originally flawless upper may gradually turn yellow and even appear mottled traces. This phenomenon not only makes the shoes lose their original brilliance, but also may affect the wearer’s self-confidence.

So, why do sneakers turn yellow? Behind this is actually a complex chemical process. Simply put, some components in the shoe material will react under external conditions such as light, oxidation or high temperature, resulting in color changes. This phenomenon is the core problem that needs to be solved by anti-yellowing agents in shoe materials. As a functional additive, anti-yellowing agent can be incorporated into the shoe material during the production process, effectively delaying or preventing the occurrence of yellowing, thereby keeping the appearance of sports shoes as long as new.

This article will in-depth discussion on the principles, applications and future development of anti-yellowing agent of shoe material, and through specific parameters and case analysis, help readers to fully understand how this “invisible guardian” injects lasting vitality into sports shoes. Let’s unveil the mystery of anti-yellowing agents together!

2. Basic principles of anti-yellowing agent for shoe material

To understand the mechanism of action of anti-yellowing agents, we first need to clarify the nature of yellowing. Yellowing is the result of a chemical reaction, usually caused by the following factors:

  1. Photooxidation: UV radiation will cause the molecular bonds in the material to break and form free radicals, which further react with other substances to form yellow compounds.
  2. Thermal Aging: In high temperature environments, the material may degrade or polymerize, resulting in fermented by-products.
  3. Oxidation reaction: The oxygen in the air binds to the unsaturated bonds in the material to form carbonyl compounds or other chromophores.

In response to the above problems, shoe material anti-yellowing agents inhibit the occurrence of yellowing through various methods, mainly including the following mechanisms:

(I) Anti-yellowing agent that absorbs ultraviolet rays

This type of anti-yellowing agent can absorb UV light and convert it into heat to dissipate it, thereby avoiding the damage to the material by UV light. For example, benzotriazole compounds are a common UV absorber that can effectively protect shoe materials from photooxidation.

Anti-yellowing agent type Main Ingredients Features
Ultraviolet absorber Benzotriazoles Absorb UV rays to prevent photooxidation
Salicylate High chemical stability

(Bi) Anti-yellowing agent that captures free radicals

Free radicals are important causes of material degradation and yellowing. Therefore, some anti-yellowing agents are specially designed to capture free radicals, thereby interrupting the chain reaction. Typical examples include phenolic antioxidants and amine antioxidants.

Anti-yellowing agent type Main Ingredients Features

How to use shoe material anti-yellowing agent to enhance the wear resistance of running shoes

3月 15th, 2025 News

The anti-yellowing and wear resistance of running shoes: the effect of anti-yellowing agent of shoe material

In today’s fast-paced lifestyle, running shoes are not only part of sports equipment, but also a choice for many people to wear every day. However, as time goes by and the frequency of use increases, running shoes are prone to aging, and the common problem is yellowing. This phenomenon not only affects the appearance of the shoe, but may also reduce its durability and functionality. To solve this problem, scientists have developed a chemical called shoe material cotton anti-yellowing agent, which is like an invisible guardian, silently protecting our running shoes.

The main function of shoe cotton anti-yellowing agent is to prevent or delay the aging process of the material, especially to prevent yellowing caused by ultraviolet rays, oxygen and other environmental factors. It’s like putting a transparent protective clothing on running shoes, allowing them to maintain their original color and texture even after long-term use and exposure to various environments. In addition, this anti-yellowing agent can enhance the wear resistance of running shoes, allowing it to accompany us for more lasting every run, jump and walk.

Through this article, we will explore in-depth how anti-yellowing agents in shoe materials play a role in improving the wear resistance of running shoes, and introduce their application methods and effect evaluation in detail. Whether you are a running enthusiast or a scholar interested in materials science, this article will provide you with rich information and practical advice. Let’s explore the secrets of how to make running shoes both beautiful and durable!

The principle and mechanism of anti-yellowing agent of shoe material

The working principle of the anti-yellowing agent of the shoe material is like a carefully designed chemical symphony, and every step is crucial. First, this anti-yellowing agent reduces the occurrence of photooxidation reactions by absorbing ultraviolet rays. When ultraviolet light hits the surface of the running shoe, it stimulates molecules to enter a high energy state, causing changes in the molecular structure, which triggers yellowing. The active ingredients in the anti-yellowing agent can absorb these harmful UV rays and convert them into heat energy to emit them, thus protecting running shoe materials from damage.

Secondly, the anti-yellowing agent of the shoe material also has anti-oxidation function. The oxygen molecules present in the air can react oxidatively with running shoe materials, which is also an important factor in yellowing. Anti-yellowing agents effectively slow down the aging rate of materials by providing electrons or hydrogen atoms, interrupting the oxidation chain reaction. This process is like injecting a shot of a cardiac into running shoes materials, enhancing their ability to resist environmental damage.

In addition, the anti-yellowing agent of the shoe material also enhances the wear resistance of running shoes by stabilizing the molecular structure of the material. During the manufacturing process, the anti-yellowing agent is evenly distributed in the shoe material to form a stable molecular network. This network not only improves the strength and toughness of the material, but also reduces tiny cracks and wear caused by friction. It’s like putting a layer of tough armor on the running shoes, allowing them to gallop freely on various complex terrains without being easily damaged.

To sum up,The anti-yellowing agent of the shoe material material uses multiple mechanisms to effectively prevent the yellowing of running shoes, but also significantly improves its wear resistance.

Examples of application of shoe material anti-yellowing agent in different shoe material

The anti-yellowing agent of shoe materials is widely used and diverse, especially in different types of shoe materials, which show different effects and advantages. Below we will explore its performance in practical applications through several specific cases.

Case 1: Application in EVA foaming materials

EVA (ethylene-vinyl acetate copolymer) is a commonly used sole material and is popular for its lightweight, soft and good cushioning properties. However, EVA is prone to yellowing under long-term light, which affects the overall appearance of the shoes. In an experiment with a well-known sports brand, researchers added shoe cotton anti-yellowing agent to EVA materials at a ratio of 1%. After six months of accelerated aging test, it was found that the yellowing index of EVA material with anti-yellowing agent was only 0.9, while the yellowing index of unadded samples was as high as 3.6. In addition, wear resistanceIt also has significantly improved, with wear reductions of about 45%. This shows that the anti-yellowing agent of the shoe material not only effectively prevents yellowing in EVA materials, but also significantly improves its durability.

Case 2: Application in TPU elastomers

TPU (thermoplastic polyurethane) is known for its high strength, high elasticity and excellent oil resistance. It is often used to make outsoles and support parts of high-performance running shoes. In a factory focusing on the production of high-end sports shoes, technicians mixed shoe anti-yellowing agent into the TPU material at a ratio of 2%. After a series of rigorous tests, including ultraviolet irradiation and wear resistance tests, the results showed that the TPU material with anti-yellowing agent improved by nearly 80% in yellowing resistance and about 50%. This allows running shoes with improved TPU materials to maintain the appearance and performance of the new shoes for longer when used outdoors.

Case 3: Application in PVC synthetic leather

PVC (polyvinyl chloride) synthetic leather is widely used in the production of waterproof shoes and outdoor shoes due to its low cost and diverse surface treatment capabilities. However, PVC materials have poor stability in sunlight and are prone to yellowing and brittleness. In an improvement project for outdoor waterproof shoes, the development team tried to add the shoe material anti-yellowing agent to PVC synthetic leather at a ratio of 1.5%. Test results show that after a year of outdoor use, the PVC synthetic leather with anti-yellowing agent has a yellowing degree that is much lower than that of unadded samples, and its wear resistance is improved by about 35%. This means that shoes with improved PVC materials can better maintain their appearance and functionality during long-term use.

Through these specific application examples, we can clearly see the excellent performance of shoe cotton anti-yellowing agents in different shoe materials. Whether it is lightweight EVA, high-strength TPU, or affordable PVC, anti-yellowing agents can significantly improve their anti-yellowing ability and wear resistance, thereby extending the service life of the shoe and maintaining its excellent appearance and function.

The current market situation and future trends of shoe material anti-yellowing agent
