Textile Deodorizing Finishing Agent DN128 is a special functional finishing agent that, through processes such as impregnation and padding, can impart deodorizing properties to textiles.
I. Mechanism of Action
The mechanism of action of textile deodorizing finishing agents mainly includes the following:
Physical Adsorption: Uses porous materials to adsorb odorous chemical components, thereby reducing the concentration of odorous substances in the air.
Chemical Deodorization: In the post-finishing process of textiles, it primarily involves applying highly efficient and stable functional chemical auxiliaries to endow textiles with deodorizing and odor-eliminating functions.
II. Product Characteristics
Textile Deodorizing Finishing Agent DN128 typically possesses the following characteristics:
Significant Deodorizing Effect: Shows clear effectiveness against sweat odor components such as ammonia, acetic acid, and isovaleric acid, significantly reducing odor concentration on textiles.
Easy to Use: Comes in the form of a water dispersion or liquid, making it easy to combine with textiles without damaging the fabric during use.
Good Durability: When used with a compatible cross-linking agent, it provides textiles with wash-resistant and long-lasting deodorizing and odor-eliminating effects.
High Safety: Complies with relevant safety standards, is harmless to humans, and does not produce harmful substances during use.
III. Application Process
The application process for textile deodorizing finishing agents mainly includes the following steps:
Dilution: Dilute the deodorizing finishing agent in a certain ratio to better combine with textiles.
Impregnation or Padding: Soak the textiles in the diluted deodorizing finishing agent or apply the agent evenly to the textiles through a padding process.
Drying: Dry the textiles at an appropriate temperature to ensure the finishing agent fully bonds with the fabric.
IV. Performance Testing
To evaluate the deodorizing performance of textiles, the following methods can be used for testing:
1. GC-MS Method: Although time-consuming, complex, and with high equipment costs, it is suitable for detecting certain specific odorous substances.
2. Sensor Method: Highly responsive, simple and quick to operate, low cost, and capable of simultaneously measuring multiple odorous substances and their concentrations. However, it is significantly affected by the composition of odorous substances, odor intensity, and environmental conditions.
3. Condensation Sampling Analysis Method: Can detect low concentrations of odorous substances, but requires stringent testing conditions, has high testing costs, and is highly specific.
In China, the GB/T 33610-2019 "Determination of Deodorizing Performance of Textiles" standard provides the index requirements for determining whether textiles have deodorizing functions. Taking sweat odor as an example, if a textile product achieves a reduction rate of ≥70% for ammonia concentration, ≥70% for acetic acid concentration, and ≥85% for isovaleric acid concentration, it is considered to have sweat odor elimination functionality. DN128 achieves an ammonia reduction rate of 93% and an isovaleric acid reduction rate of 99.3%, demonstrating excellent deodorizing performance.

V. Application Areas

Textile Deodorizing Finishing Agent DN128 is widely used in the post-finishing processes of various textiles, including home textiles, apparel, underwear, shoe materials, towels, and more. By adding the deodorizing finishing agent, these textiles can achieve better deodorizing and odor-eliminating functions, meeting consumers' demands for healthy and comfortable living.

When using Textile Deodorizing Finishing Agent DN128, relevant safety operating procedures should be followed to avoid harm to humans and the environment.
Store DN128 in a cool, dry, and well-ventilated place, avoiding direct sunlight and high temperatures.
During use, attention should be paid to controlling the dosage and concentration of the finishing agent to ensure optimal deodorizing effects.
In summary, Textile Deodorizing Finishing Agent DN128 is an efficient, convenient, and safe functional textile auxiliary that significantly enhances the deodorizing performance and market competitiveness of textiles.
