Bust squid anti-yellowing agent: an efficient strategy to reduce odor during production

In the modern textile industry, as a common material, its performance and quality directly affect the comfort and aesthetics of the final product. However, during the production process, the bust cotton is susceptible to external factors and produces odor, which not only affects the quality of the product, but also has adverse effects on the production environment and workers’ health. To solve this problem, scientists have developed a chemical additive called “Bust Sponge Anti-Yellowing Agent”, which not only effectively prevents the bust Sponge from yellowing due to oxidation or photoaging, but also significantly reduces odor during the production process. This article will discuss in-depth how bust anti-yellowing agents can become a powerful tool to solve the problem of producing odor from multiple aspects such as product parameters, mechanism of action, current domestic and foreign research status, and application strategies.

1. Introduction to the anti-yellowing agent for bust circumference

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

Bust cotton anti-yellowing agent is a chemical additive specially used to prevent the yellowing of the bust cotton material. Its main function is to suppress the oxidation reaction and photodegradation process, extend the service life of the bust and maintain the whiteness and texture of its appearance. In addition, this additive also has a certain adsorption capacity and can effectively capture the volatile organic compounds (VOCs) generated during the production process, thereby reducing the emission of odor.

(II) The principle of action of bust anti-yellowing agent

Antioxidation
During the production process, bust cotton is susceptible to external factors such as oxygen and ultraviolet rays, causing the molecular chain to break and free radicals to form. These free radicals will further trigger a chain reaction, causing the material to gradually turn yellow or even deteriorate. Anti-yellowing agents interrupt this reaction chain by providing electrons or capturing free radicals, thereby protecting the stability of the material.
Photostabilization
Anti-yellowing agents can also absorb ultraviolet energy and convert it into harmless heat energy to release it, avoiding the direct damage of ultraviolet rays to the bust.
odor adsorption
During the production process, certain chemical reactions will produce gases with irritating odors, such as ammonia, hydrogen sulfide, etc. The active ingredients in the anti-yellowing agent can be chemically combined with these gases or physically adsorbed, thereby reducing their concentration and achieving the effect of reducing odor.

(III) Product parameters of bust anti-yellowing agent

The following is the main technical parameter list of bust anti-yellowing agent:

parameter name	parameter value	Remarks
Appearance	White powder/transparent liquid	Different depending on the model
Active ingredient content	?98%	High purity, better effect
Volatility	?0.5%	Low volatile, environmentally friendly
Melting point	45-55?	Suitable for most production processes
Density	1.1-1.3 g/cm³	Easy to measure and use
Temperature range	-20? to +120?	Widely adapted to various processing conditions
Add ratio	0.5%-2.0%	The specific dosage needs to be adjusted according to actual conditions

(IV) Advantages of bust anti-yellowing agent

Improve product quality
After using anti-yellowing agent, the color of the bust circumference is more durable, the surface is smooth and delicate, and the feel is soft, greatly enhancing the market competitiveness of the product.
Improve the production environment
Reducing odor during production can not only improve workers’ work comfort, but also reduce the risk of occupational diseases.
Environmentally friendly
The anti-yellowing agent itself has good biodegradability and will not cause secondary pollution to the environment, which is in line with the concept of green development.

2. Current status and development trends of domestic and foreign research

(I) Progress in foreign research

In recent years, European and American countries have achieved remarkable results in research on yelating agents. For example, a chemical company in the United States has developed a new nano-scale anti-yellowing agent with a particle size of only a few dozen nanometers and can be evenly dispersed inside the bust cotton, forming an efficient protective barrier. The German research team focused on exploring the synergistic effects of anti-yellowing agents and antibacterial agents. They found that when the two were combined, they not only inhibit yellowing, but also effectively killed bacteria, further optimizing the hygiene performance of the product.

In addition, Japanese companies have also invested a lot of resources in the anti-yellowing agent field.We focus on developing multifunctional composite additives and strive to achieve the goal of multi-purpose single product. For example, a comprehensive additive that integrates anti-yellowing, anti-mold and deodorizing has been widely used in the market.

(II) Current status of domestic research

in the country, with the rapid development of the textile industry, the demand for anti-yellowing agents has increased year by year. At present, my country has mastered a number of core technologies, and the performance of some products has reached the international advanced level. For example, a study by East China University of Science and Technology showed that by introducing specific metal ion catalysts, the activity of anti-yellowing agents can be significantly enhanced while reducing their costs. This research result has been practically applied in many companies.

However, compared with developed countries, there is still a certain gap in basic research in my country in the field of anti-yellowing agents, especially in the independent research and development capabilities of high-end products need to be strengthened. In the future, we need to increase investment in scientific research, focus on overcoming key technical problems, and promote the improvement of the overall technical level of the industry.

(III) Development Trend

Intelligent direction
With the development of artificial intelligence and big data technology, the future anti-yellowing agent may develop in the direction of intelligence. For example, the status of the bust is monitored in real time by sensors and the amount of anti-yellowing agent is automatically adjusted to achieve the best effect.
Green and environmentally friendly
In the context of global advocacy of sustainable development, the development of more environmentally friendly anti-yellowing agents will become an inevitable trend. This includes the use of renewable raw materials and reducing harmful by-product emissions.
Multifunctional
Single-function additives are difficult to meet the increasingly complex application needs, so developing composite anti-yellowing agents with multiple functions will be an important research direction in the future.

3. Application strategies for bust anti-yellowing agents in reducing production odors

(I) Choose the right type of anti-yellowing agent

Depending on the specific use and processing technology of the bust cotton, different types of anti-yellowing agents can be selected. For example, for bust cotton that requires high temperature treatment, anti-yellowing agents with excellent heat resistance should be selected; while for products with high appearance requirements, additives with good whiteness retention should be given priority.

(II) Optimization of the addition process

Rational addition process is the key to fully exerting the effectiveness of anti-yellowing agents. Here are some practical suggestions:

Control the amount of addition
Excessive additions not only increase costs, but may also lead to other side effects, such as affecting the flexibility or breathability of the material. Therefore, the recommended ratio must be strictly followedMake the addition.
Ensure uniform dispersion
If the anti-yellowing agent cannot be fully dispersed in the bust, local protection may occur. This problem can be solved by improving the mixing equipment or adjusting process parameters.
Add in stages
In some cases, a phased addition method can be adopted, that is, first add a portion of the anti-yellowing agent for preliminary treatment, and then supplement the remaining part according to actual conditions. This method can better balance costs and effects.

(III) Cooperate with other measures to control odor

While anti-yellowing agents are outstanding in reducing production odors, it may not be enough to completely solve the problem by relying on them alone. Therefore, other auxiliary measures need to be taken, such as strengthening ventilation, regular cleaning of production equipment, reasonable arrangement of production processes, etc., to form a comprehensive governance system.

IV. Case Analysis

In order to more intuitively demonstrate the practical application effect of bust anti-yellowing agent, we selected a typical case for analysis.

(I) Background Introduction

A well-known underwear manufacturer encountered serious odor problems during the production process, which not only affected the product quality, but also received multiple complaints from employees. After investigation, it was found that the root of the problem is that the bust cotton material undergoes an oxidation reaction at the high-temperature setting stage, producing a large number of volatile organic compounds.

(II) Solution

In response to the above problems, the company introduced a high-performance bust anti-yellowing agent and adjusted its production process accordingly. Specific measures include:

Increase the proportion of the anti-yellowing agent from the original 1% to 1.5% to enhance the protective effect.
Improve the design of the stirring device to ensure that the anti-yellowing agent can be evenly distributed throughout the bust.
Add pretreatment steps before high temperature setting to activate the active ingredient of the anti-yellowing agent in advance.

(III) Implementation effect

After a period of operation, the company’s production environment has been significantly improved, the odor concentration has been reduced by more than 80%, and the product quality has also been significantly improved. More importantly, employees’ job satisfaction has been greatly improved and their corporate image has been further consolidated.
