Fogging systems for textile spinning and weaving mills.
Relative humidity changes yarn strength, elongation and static. TrueMist textile fogging systems pressurise treated water to 70–140 bar and fog it through precision nozzles to hold RH in spinning, weaving and ring-frame departments.

Moisture regain and yarn quality
Moisture regain – the ratio of moisture to bone-dry weight – changes many properties of textile materials and depends on ambient RH and temperature. Temperature alone has little effect on fibres, but it sets how much moisture the air can hold, so the two must be controlled together.
- Cotton strength rises as RH rises
- Viscose strength falls as RH rises
- Elongation increases with RH for most fibres
- Static from friction falls as RH rises
- At very high RH fibres tend to stick together
Engineered for each mill
Every TrueMist textile system is designed for the department: our engineers size water treatment and the fog system from building heat loads, ambient climate data and ventilation rates. Direct water pressure means few moving parts – none in air handlers or the humidified space – and energy use is a small fraction of compressed-air, ultrasonic or steam humidifiers. Systems can be automated and monitored remotely, helping mills meet indoor air quality requirements.
Design inputs
- Department, machines and heat load
- Target RH and temperature by department
- Air changes and existing supply air plant
- Water treatment available
Good to know
- Hold RH steady – swings hurt quality more than slightly lower RH
- Treated water prevents mineral dust on yarn
How a TrueMist project runs

Tell us what is happening, where and when.
- 02
Assess the conditions
Area, airflow, humidity, water and power on site.
- 03
Define the system
Pump, nozzles, lines, filtration and controls sized to the duty.
- 04
Install & validate
Commissioning checks against the agreed objective.

Questions we are often asked
Will the fog cause dampness on the cloth?
No. Correctly controlled fog evaporates before it reaches yarn or fabric.
Can the system run in cycles, for example every 5 minutes?
Yes. A timer and humidistat are provided as part of the system.
Will there be a reduction in temperature?
Yes. Temperature reduction is a key goal along with humidity maintenance.
Will it remove dust and fly?
Yes – the fog also settles dust, pollen and airborne lint.
