Bust circumference anti-yellowing agent: a choice to meet the market demand for high-standard underwear in the future

1. Introduction

In today’s intertwined fashion and technology, the underwear industry is undergoing an unprecedented change. Consumers’ demand for underwear has long surpassed basic functionality and has turned to a more comfortable, healthy and lasting product experience. As an important part of underwear, the quality of the bust sponge (commonly known as “sponge”) directly affects the overall performance of the underwear. However, in daily use, bust cotton is easily affected by the external environment, especially the effects of ultraviolet rays and high temperatures, which leads to yellowing. This phenomenon not only affects the appearance of the product, but may also reduce consumers’ willingness to buy and even damage the brand’s reputation.

To solve this problem, bust anti-yellowing agents emerged. As a highly efficient additive, it can significantly delay or prevent yellowing caused by oxidation or other chemical reactions during long-term use of the bust. This is not only a technological breakthrough, but also an inevitable demand for market development. With the continuous improvement of consumers’ requirements for product quality and the increased awareness of environmental protection, choosing the right anti-yellowing agent has become one of the focus of underwear manufacturers.

This article will discuss the application value of bust anti-yellowing agent and its far-reaching impact on the underwear market from multiple angles. We will introduce in detail the working principle, types and application methods of anti-yellowing agents, and compare and analyze relevant domestic and foreign literature to show its actual effect in improving the quality of underwear. At the same time, we will also explain in light of specific cases how to choose a suitable anti-yellowing agent solution based on market demand, providing a reference for the sustainable development of the underwear industry.

Next, let’s take a deeper understanding of the true appearance of this “invisible hero” in the bust!

2. Basic concepts of bust anti-yellowing agent

(I) What is a bust anti-yellowing agent?

Bust cotton anti-yellowing agent is a chemical additive specially used to improve the aging resistance of bust cotton. Its main function is to prevent or slow down the yellowing of the bust cotton material by inhibiting the generation of free radicals or capturing the formed free radicals. Simply put, anti-yellowing agent is like a dedicated “guardian”, always protecting the bust from harmful external factors.

In the underwear manufacturing process, the bust cotton is usually made of polyurethane foam (PU Foam). This material has good elasticity and breathability, but it also has a fatal weakness – it is prone to yellowing due to light, high temperatures or chemical contamination. Yellowing will not only make the underwear look old, but it will also weaken its physical properties and shorten its service life. The introduction of anti-yellowing agents effectively alleviates this problem and allows the bust to maintain its original color and texture for a longer period of time.

(II) Working principle of anti-yellowing agent

The reason why anti-yellowing agents can work mainly depends onin its unique molecular structure and chemical mechanism. Here are the core points of its working principle:

Free radical scavenging
Under ultraviolet light, the polymer chains in the bust cotton will break and form free radicals. These free radicals further trigger a chain reaction, causing the material to degrade and release the yellow substance. Anti-yellowing agents can terminate this process by binding to free radicals to convert them into stable compounds.
Ultraviolet absorption function
Certain types of anti-yellowing agents also have the ability to absorb ultraviolet rays, which can convert the energy of ultraviolet rays into heat and dissipate them, preventing the ultraviolet rays from directly acting on the internal structure of the bust rays.
Antioxidation properties
Anti-yellowing agents can also neutralize the oxidant by providing electrons or hydrogen atoms, reducing the frequency of oxidation reactions, and thus extending the life of the bust.

(III) Classification of anti-yellowing agents

Depending on the chemical composition and mechanism of action, bust anti-yellowing agents can be divided into the following categories:

Category	Main Ingredients	Features
Ultraviolet absorber	Benzotriazoles, salicylates	Specially targets yellowing caused by ultraviolet rays, it is suitable for bust cotton products in outdoor exposure scenarios.
Free Radical Capture	Stealed phenols and phosphites	Breast cotton materials that require long-term stability are prevented by capturing free radicals.
Light Stabilizer	Nylonamides	Improve the resistance of bust cotton to strong light and often be used in combination with other anti-yellowing agents to achieve the best results.
Compound anti-yellowing agent	Combining multiple active ingredients	Integrates multiple functions into one, which can absorb ultraviolet rays and capture free radicals, and is widely used in high-end underwear products.

Each type has its specific application areas and advantages. The specific choice must be determined based on the actual use of the bust and the target market.

3. Technical parameters and performance evaluation of bust anti-yellowing agent

(I) Key PerformanceIndicators

In order to ensure the effectiveness of the anti-yellowing agent in the bust, we need to pay attention to the following core parameters:

Initial whiteness retention rate
The initial whiteness retention rate refers to the retention ratio of the whiteness of the bust with respect to the original state after a certain period of light or high temperature treatment. Generally speaking, high-quality anti-yellowing agents should be able to achieve an initial whiteness retention rate of more than 90%.
Heat resistance
Heat resistance reflects the ability of anti-yellowing agents to maintain stable performance under high temperature environments. For underwear production, bust cotton usually needs to withstand a heat setting process of 120℃~150℃, so the anti-yellowing agent must have good heat resistance.
Migration
Mobility is whether the anti-yellowing agent will ooze or transfer to other parts. If the mobility is too high, it may cause oil stains on the surface of the bust or affect the adhesion effect of other materials.
Compatibility
Compatibility determines whether the anti-yellowing agent can coexist well with the bust cotton substrate and other additives (such as softeners, crosslinkers, etc.) without adverse reactions.

parameter name	Test Method	Standard Value Range	Practical Meaning
Initial Whiteness Retention Rate	ASTM D6290-18	≥90%	Measure the ability of anti-yellowing agents to control color changes
Heat resistance	ISO 105-B02	≤±5℃ deviation	Ensure that the product does not lose its stability under high temperature conditions
Migration	DIN EN 71 Part 3	≤0.1mg/cm²	Prevent anti-yellowing agent from oozing, causing contamination or damage to other components
兼容性	ASTM D1141-07	No obvious stratification or precipitation	Ensure that all ingredients in the formula system work together

(II) Performance evaluation method

Accelerating aging test
An artificial climate box was used to simulate the changes in light, humidity and temperature under natural environmental conditions, and observe the color changes of the bust cotton sample over different time periods. This is one of the straightforward ways to evaluate the effectiveness of anti-yellowing agents.
Dynamic Mechanical Analysis (DMA)
By measuring the changes in the mechanical properties of the bust cotton at different temperatures, it is determined whether the anti-yellowing agent has a negative impact on its elastic modulus and loss factor.
Chemical stability test
The bust cotton sample containing the anti-yellowing agent is placed in an acidic or alkaline solution for a period of time, and then the physical properties are detected to be changed. This approach can help determine the suitability of anti-yellowing agents in extreme chemical environments.

The basic principles and mechanism of bust anti-yellowing agent

Bust cotton anti-yellowing agent is an advanced chemical additive. Its basic principle is to protect the color stability of the bust material by inhibiting chemical reactions that cause yellowing. Yellowing is usually caused by chemical reactions in certain components in the material during ultraviolet irradiation, high temperatures or oxidation environments. These reactions can cause changes in the molecular structure, resulting in yellow substances. The bust anti-yellowing agent prevents these harmful reactions from occurring by providing a barrier, ensuring that the bust material maintains its original color during long-term use.

Specifically, the mechanism of action of anti-yellowing agents is mainly divided into two categories: absorption type and stable type. Absorbent anti-yellowing agents prevent photodegradation reactions caused by ultraviolet rays by absorbing ultraviolet rays and converting them into thermal energy. This type of anti-yellowing agent is especially suitable for products that require frequent exposure to the sun. On the other hand, stable anti-yellowing agents slow down the oxidation process by capturing free radicals and other reactive oxygen species. This type of anti-yellowing agent is more suitable for indoor use products as they can effectively slow down material aging caused by oxygen in the air.

In addition, bust anti-yellowing agent can also improve the materialheat resistance and oxidation resistance. This means that the bust retains its original color and physical properties even under high temperature ironing or drying conditions. This is especially important for busy people in modern life, as they often rely on fast and efficient clothing care methods. By reducing the occurrence of yellowing, anti-yellowing agents not only enhance the visual appeal of underwear, but also enhance consumer satisfaction and loyalty.

To sum up, the bust anti-yellowing agent protects the bust material from external environmental factors through complex chemical processes, thereby significantly extending the service life and aesthetics of underwear products. The application of this technology not only meets consumers’ demand for high-quality underwear, but also opens up new market opportunities for the underwear manufacturing industry.
