Keywords Polyurethane sponge; deodorant; sports products; odor improvement; raw material selection; finished product inspection

Introduction

With people’s living standards improving and health awareness increasing, the market demand for sports goods continues to grow. However, many sporting goods produce unpleasant odors during use, which not only affects the user experience, but can also pose a potential threat to the user’s health. As a widely used material in sporting goods, polyurethane sponges have particularly prominent odor problems. Therefore, studying how to effectively improve the odor of polyurethane sponges is of great significance to improving the quality of sports goods.

Polyurethane sponge deodorant, as a chemical agent specially developed for polyurethane materials, can effectively neutralize or eliminate odor molecules in the material. This article aims to explore the actual effect of polyurethane sponge deodorant in improving the odor of sports products through systematic research and analysis. From raw material selection to finished product inspection, we will comprehensively examine the application process of flavor deodorants to provide scientific basis and practical guidance for the sports goods manufacturing industry.

The significance of this study is: first, through in-depth analysis of the odor source of polyurethane sponges and the mechanism of action of deodorants, it provides a theoretical basis for the research and development and application of deodorants; second, through systematic research on the formulation design and production process optimization of deodorants, it provides an operational solution for actual production; and then, through practical application cases and data analysis, the effect of deodorants is objectively evaluated, and a decision-making reference is provided for sports goods manufacturers.

1. Analysis of the characteristics and odor source of polyurethane sponges

Polyurethane sponge is a polymer material produced by the reaction of polyols and isocyanates. It has excellent properties such as lightweight, good elasticity, sound absorption and heat insulation. Its unique open hole structure makes it widely used in sports goods, such as sports insoles, protective gear, fitness equipment, etc. However, it is this porous structure that also makes polyurethane sponges easy to adsorb and release volatile organic compounds (VOCs), becoming the main source of odor.

The smell of polyurethane sponge is mainly due toIt originates from the following aspects: first, residual monomers and small-molecular compounds in the raw materials, such as isocyanates and polyols that are not fully reacted; second, additives such as catalysts, foaming agents used in the production process; second, environmental pollutants adsorbed during storage and use of the material; afterward, the material ages and degrades the volatile substances produced. These odor ingredients not only affect the user experience, but may also cause potential harm to human health.

Deodorant plays a key role in improving the odor of polyurethane sponge. Its mechanism of action mainly includes three methods: physical adsorption, chemical neutralization and coating isolation. Physical adsorption captures odor molecules through adsorbents such as porous materials or activated carbon; chemical neutralization uses specific chemical substances to react with odor molecules to produce odorless or low-odor products; coating and isolation prevents the release of odor molecules by forming a thin film on the surface of the material. In practical applications, a synergistic method of multiple mechanisms is often used to achieve the best deodorization effect.

2. Raw materials selection and formula design of polyurethane sponge deodorant

Selecting the right raw materials is the key to developing high-efficiency polyurethane sponge deodorants. Commonly used raw materials include adsorbents (such as activated carbon, diatomaceous earth), neutralizing agents (such as cyclodextrin, metal oxide), coating agents (such as silane coupling agents, polymer emulsions), etc. When choosing raw materials, it is necessary to consider factors such as its compatibility with polyurethane sponge, deodorization effect, safety and cost. For example, activated carbon has excellent adsorption properties, but excessive use may affect the mechanical properties of the material; cyclodextrin can effectively inclusion of odor molecules, but may increase the hydrophilicity of the material.

The formulation design of deodorant needs to consider a variety of factors. First, you should select the appropriate odor removal mechanism and raw material combination according to the characteristics of the target odor components. For example, for acidic odors, alkaline neutralizers can be used; for volatile organic compounds, adsorbents with high specific surface area can be used. Secondly, the compatibility of the deodorant and polyurethane sponge production process should be considered to ensure that the deodorant will not affect the foaming and curing of the material during processing. In addition, it is necessary to balance the relationship between the deodorization effect and material performance and cost, and seek an excellent formula.

The performance testing of deodorants is an important means to evaluate their effectiveness. Commonly used testing methods include gas chromatography-mass spectrometry (GC-MS) analysis, odor sensory evaluation, VOCs content determination, etc. GC-MS can accurately identify and quantify odor components, providing a scientific basis for the selection and optimization of deodorants; odor sensory evaluation reflects the actual effect of deodorants through subjective evaluation by professional olfactory experts; VOCs content determination can quantify the total amount of volatile organic matter in the material and evaluate the overall effect of deodorants. Through these testing methods, the performance of deodorants can be comprehensively evaluated and data support for formula optimization can be provided.

III. Optimization of production process of polyurethane sponge deodorant

The addition of deodorant has an important impact on the final effect. Common addition methods include premixing, impregnation and spraying. Premix method is to removeThe odorant is directly added to polyurethane raw materials and mixed, which is suitable for large-scale production, but may affect the foaming process of the material; the immersion method is to soak the molded polyurethane sponge in the deodorant solution, which is suitable for small-scale production or post-processing, but may affect the mechanical properties of the material; the spraying method is to spray the deodorant solution on the surface of the material, which is easy to operate, but may cause uneven distribution of the deodorant. Choosing a suitable addition method requires comprehensive consideration of factors such as production scale, material characteristics and deodorization effect.

The optimization of production process parameters is the key to ensuring the effect of deodorants. The main parameters include temperature, time, pressure, stirring speed, etc. For example, in the premix method, it is necessary to optimize the stirring speed and temperature to ensure that the deodorant is evenly dispersed without affecting the chemical reaction of the raw materials; in the impregnation method, it is necessary to control the immersion time and temperature to balance the deodorization effect and material properties. In addition, factors such as humidity and ventilation in the production environment need to be considered, which may affect the effect of the deodorant and the performance of the material.

Quality control is an important part of ensuring the stability of the deodorant effect. First of all, a strict raw material inspection system must be established to ensure the consistency of quality of each batch of raw materials. Secondly, during the production process, key process parameters must be monitored in real time and problems must be discovered and solved in a timely manner. Afterwards, a comprehensive performance test of the finished product should be carried out, including deodorization effect, material performance and safety performance. By establishing a complete quality control system, the stability and reliability of the deodorant effect can be ensured and the market competitiveness of the product can be improved.

IV. Evaluation of the application effect of polyurethane sponge deodorant in sports goods

To objectively evaluate the actual effect of polyurethane sponge deodorant in sporting goods, we selected three typical sporting goods for case analysis: sports insoles, yoga mats and fitness gloves. These products use polyurethane sponge materials in large quantities and are in close contact with users, which have high requirements for odor control.

In the application of sports insoles, we compared the odor sensory evaluation and VOCs content before and after the use of deodorant. The results showed that after using the deodorant, the odor level of the insole decreased from level 3.5 (significant odor) to level 1.5 (slight odor), and the VOCs content was reduced by 65%. User feedback shows that the insole after the use of deodorant significantly improves wear comfort, especially after prolonged exercise, the odor of the feet is significantly reduced.

In the application case of yoga mats, we focused on the durability of deodorants. Through accelerated aging test and actual use tracking, it was found that after 100 hours of use, the odor level of the yoga mat using the deodorant remained below level 2, while the control group without the deodorant rose to level 3. This shows that deodorants can not only effectively improve the initial odor, but also have good durability.

The application of fitness gloves demonstrates the effect of deodorants on material properties. Test results show that the tensile strength and resilience of the gloves have slightly improved after using the deodorant, which may be due to the enhancement of some of the ingredients in the deodorant. at the same time,The breathability of the gloves remains unchanged, indicating that the deodorant does not block the open structure of the polyurethane sponge.

By comparing and analyzing the use effects of different sports goods, we found that the effect of deodorants is affected by a variety of factors, including product type, usage environment, usage frequency, etc. For example, sports insoles are often exposed to sweat, and have high requirements for deodorant water resistance and durability; while yoga mats need to consider the compatibility of deodorant with human skin. These findings provide an important reference for targeted optimization of deodorants.

User feedback and market response are important indicators for evaluating the effectiveness of deodorants. Through surveys of users using deodorant sports products, we found that more than 85% of users expressed satisfaction with the improved odor, of which about 30% believed that the odor improvement significantly improved the product usage experience. In the market, sales of sporting goods using deodorants increased by 15% year-on-year, and the return rate fell by 40%. These data fully demonstrate the positive role of deodorants in improving product competitiveness and market acceptance.

5. Finished product inspection and effect verification

In order to ensure the actual effect of polyurethane sponge deodorant, we have established a complete finished product inspection system. The system includes four aspects: odor testing, VOCs content determination, material performance testing and safety performance evaluation. Odor tests are scored by trained professional olfactory personnel; VOCs content determination uses gas chromatography-mass spectrometers to accurately identify and quantify various volatile organic compounds; material performance tests include indicators such as tensile strength, resilience, and permanent compression deformation; safety performance evaluation includes biocompatibility tests such as skin irritation and sensitization.

The test results show that the polyurethane sponge material using deodorant has significantly improved in all indicators. The odor score was reduced by 2 levels on average, and the VOCs content was reduced by more than 60%. In terms of material properties, the tensile strength is improved by 10%, the elasticity is improved by 5%, and the permanent compression deformation is reduced by 15%. Safety performance tests show that deodorants will not cause skin irritation or allergic reactions and fully meet relevant safety standards.

Effect verification is a key step in ensuring the practical application value of deodorants. We comprehensively evaluate the long-term effects of deodorants through a combination of laboratory testing and actual use tracking. Laboratory tests include accelerated aging tests, humidity and heat cycle tests, etc., to simulate various environmental conditions of the product in actual use. Actual usage tracking collects performance data of the product in the real usage environment through user feedback and regular inspections.

Verification results show that the effect of the deodorant has good stability. After 1000 hours of accelerated aging test, the performance retention rate of the deodorant is still above 90%. Actual use tracking data shows that after 6 months of use, the product’s odor grade and VOCs content remained at a low level, and the user satisfaction remained above 85%. These results fully demonstrate the reliability and maintenance of deodorants in practical applicationsLongevity.

VI. Conclusion

This study explores the practical effects of polyurethane sponge deodorant in improving the odor of sports products through systematic theoretical analysis and practical verification. The research results show that rational selection and optimization of polyurethane sponge deodorant can significantly improve the odor of sports goods and enhance the user experience. The specific conclusions are as follows:

  1. The odor of polyurethane sponges mainly comes from raw material residues, production additives, environmental pollutants and material degradation products. The deodorant effectively reduces the odor components in the material through mechanisms such as physical adsorption, chemical neutralization and coating isolation.

  2. The raw material selection and formulation design of deodorant need to comprehensively consider factors such as deodorization effect, material properties and production process.
