A Comprehensive Record of Textile Odors: Sources, Effects, and Control Strategies

Textile odors are a ubiquitous problem in the textile industry, affecting not only consumers but also workers and the environment. The sources of textile odors can be attributed to various factors such as chemicals used during production, fabric finishing processes, and storage conditions. These odors can have negative effects on human health, causing respiratory problems and headaches, as well as damaging clothing and furniture. Additionally, textile odors can contribute to environmental pollution, posing risks to wildlife and ecosystems. To address this issue, several control strategies have been proposed, including the use of natural odor absorbers like activated charcoal, baking soda, and vinegar. Other approaches involve incorporating odor-neutralizing compounds into fabrics during production or using ozone technology for air purification. Despite these efforts, effective and sustainable control strategies remain a challenge due to the complex nature of textile odors and the need for continuous monitoring and evaluation. A comprehensive record of textile odors is essential for understanding their sources, effects, and control strategies, enabling the industry to develop more effective solutions that prioritize consumer health and environmental sustainability.

Abstract:

Textile odors have long been a source of concern for both consumers and manufacturers. This study aims to document the various sources, effects, and control strategies employed in addressing textile odors. By analyzing existing literature, interviews with industry experts, and laboratory experiments, we have compiled a comprehensive record of textile odors that can inform future research and development of effective odor control techniques.

1. Introduction

The production and use of textile products are widespread worldwide, with applications in clothing, bedding, upholstery, and many other industries. While these products offer numerous benefits, they can also emit odors that may be unpleasant or even harmful to human health and the environment. Textile odors can originate from various sources, such as raw materials, manufacturing processes, finishing treatments, and end-use environments. Understanding the characteristics and impact of these odors is crucial for developing effective odor control strategies that meet consumer needs while minimizing environmental impacts.

This study seeks to document the various sources, effects, and control strategies employed in addressing textile odors. By reviewing existing literature, conducting interviews with industry experts, and conducting laboratory experiments, we aim to compile a comprehensive record of textile odors that can inform future research and development of effective odor control techniques. The results of this study will contribute to improving the quality of textile products and enhancing consumer satisfaction.

2. Sources of Textile Odors

2、1 Raw Materials

Raw materials are a significant source of textile odors. For example, cotton contains natural oils and proteins that can give it a pleasant smell when fresh. However, during processing and storage, these oils and proteins may degrade, releasing volatile organic compounds (VOCs) and odorous compounds that can cause off-gassing and odor problems. Similarly, synthetic fibers such as polypropylene (PP), polyester (PET), and nylon (NY) can emit strong smells when exposed to heat or moisture. In addition to VOCs and odorous compounds, some raw materials may contain trace amounts of heavy metals, pesticides, or other chemicals that can also contribute to odor issues.

2、2 Manufacturing Processes

Manufacturing processes can also contribute to textile odors through several pathways. For instance, during fabric finishing treatments such as dyeing, printing, or drying, VOCs and odorous compounds may be generated by the reaction between the chemicals used in the process and the fabric's structure. These emissions can be trapped within the fabric itself or released into the surrounding air, causing off-gassing and odor problems. Additionally, during fabric weaving or sewing processes, the use of solvents, oils, or other chemicals can also contribute to odor issues. Finally, during packaging and transport operations, textile products may come into contact with dust, dirt, or other contaminants that can exacerbate odor problems.

2、3 Finishing Treatments

Finishing treatments are applied to textile products to enhance their appearance, performance, or comfort. However, these treatments can also introduce new sources of odor if not applied properly or if they contain volatile organic compounds (VOCs) or other chemical compounds that emit strong smells upon exposure to heat or moisture. Examples of finishing treatments commonly used in textile products include ironing treatments (such as using an iron to smooth out wrinkles), steam treatment (using hot water vapor to remove wrinkles), and stain treatment (using chemicals to prevent or remove stains).

2、4 End-Use Environments

End-use environments play a critical role in determining how textile products interact with the atmosphere and generate odors. For example, indoor textile products such as carpets, upholstery, and curtains may release odors due to their close proximity to people
