Why does the textile industry need humidifiers? Textile fibers and fabrics are sensitive to air quality and humidity. If the air is too dry, they lose its elasticity and can break easily. In dry air, a lot of dust from the fabrics and threads floats and worsens the air quality. All this deteriorates the efficiency of the production process and the quality of the final product.
Industrial Humidification in the Textile Industry
All textiles are hygroscopic, which means that there is an exchange of moisture between the fabric and the air. When the air humidity is lower than the relative humidity of the material, they lose their moisture, and vice versa, when the humidity is high, they absorb it. Air humidity is therefore a factor, that has to be taken into an account in textile plants. Industrial humidifiers ensure the regulation of air humidity in production.
The optimal air humidity depends on the processed materials. For example, cotton is very fragile and needs air humidity of around 65%. In lower air humidity, the fabric will weaken and tear. In higher air humidity, the cotton threads will become unyielding and difficult to process. The recommended air humidity for wool is also 65%. For artificial fibers we need a lower air humidity, 45% RH is recommended.
Optimum air humidity ensures that textiles retain their strength and elasticity. By changing just one factor, and setting the humidity to the recommended values, you will get a better quality product. Such yarn is also less likely to get stuck in the machine during weaving.
Too low air humidity also leads to a decrease in the weight of the final product. Considering that textile yarn is sold by weight, the factory has a lower profit as a result, as it de facto needs to produce more yarn. The air humidification system in the textile plant ensures that the moisture loss of the final products is not the traditional 4% but only 0.5%.
Static electricity is created primarily during the processing of synthetic materials, such as perlon or nylon. These materials are more difficult to work with as in dry air they tend to stick to other materials. Productivity and product quality are thus reduced.
Accumulated static electricity causes problems also with machines. At a low level of humidity, there is a lot of friction and the machines get stuck more frequently.
When the optimal relative air humidity is established, electric static discharge is significantly reduced.
Safe Work Environment
With stable, optimal air humidity, workers have a better working environment. Dry fog humidification helps to reach the optimal relative humidity, reduces dust, and also cools. Water droplets sprayed into the air can cool the space by up to 5°C during evaporation. In such an environment it is easier to work and employees are much more effective.
Dry fog humidification is an effective method of cooling and humidifying the air without wetting the environment or people. Industrial nozzles spray dry fog – miniature droplets of water that, thanks to their small size, evaporate while still in the air and never reach the surface. This humidification system requires minimum maintenance and has very low operating costs compared to traditionally used steam humidifiers.
- Reduction of downtime
- Increase in productivity and quality of products.
- Elimination of electrostatic discharge.
- A healthier and more pleasant working environment helps increase the efficiency of employees and prevents accidents.
- Reduction of operating costs due to air cooling that accompanies adiabatic humidification.
