Fogging System For Humidification In Textile, Spinning & Weaving Mills

In a world increasingly dependent on humidification technology, VAI industries helps its customers dramatically reduce energy costs while meeting today’s more stringent indoor air quality (IAQ) requirements.

The VAI Fog system uses high-pressure pumps to pressurize treated supply water to between 1000 and 2000 psi. The stainless steel orifice of Fog nozzles atomize the water into billions of ultra-fine fog droplets.

VAI Fog systems do not require compressed air or heat. Direct pressure means there are few moving parts (none in the air handlers or the humidified space). The energy consumed is a small fraction of that required by other technologies, such as compressed air, ultra-sonic, or canister steam systems.

Every VAI Fog system is carefully and thoroughly engineered to fit the application. Our engineering staff will design the proper water treatment system and size the fog system based on building heat loads, ambient climate data, ventilation rates, etc.

IMPORTANCE OF RH & TEMPERATURE IN SPINNING, WEAVING & TEXTILE

The atmospheric conditions with respect to temperature and humidity play very important part in the manufacturing process of textile yarns and fabrics. The properties like dimensions, weight, tensile strength, elastic recovery,  lectrical resistance, rigidity etc. of all textile fiber whether natural or synthetic are influenced by Moisture Regain.

Moisture regain is the ratio of the moisture to the bone-dry weight of the material expressed as a percentage.

Many properties of textile materials vary considerably with moisture regain, which in turn is affected by the ambient Relative Humidity (RH) and Temperature. If a dry textile material is placed in a room with a particular set of ambient conditions, it absorbs moisture and in course of time, attains equilibrium.

Some physical properties of textile materials which is affected by RH is given below:

Strength of COTTON goes up when R.H.% goes up

Strength of VISCOSE goes down when R.H.% goes up

Elongation %ge goes up with increased R.H.% for most textile fibers

The tendency for generation of static electricity due to friction decreases as RH goes up

At higher levels of RH , there is also a tendency of the fibers to stick together

  Temperature alone does not have a great effect on the fibers. However the temperature dictates the amount of moisture the air will hold in suspension and , therefore, temperature and humidity must be considered together.
