Introduction:


Air conditioning in spinning of fiber has many benefits, that enhance the profitability of the process & product. Properties like dimensions, tensile strength, elastic recovery, electrical resistance, rigidity, etc. of all textile fiber whether natural or synthetic are influenced by moisture regain, which is controlled by the conditioning of air in the mill.


There are not many occasions where cotton spinning humidity is more of an issue than during the processing of textiles. Get it wrong and it can stop productions, damage machinery, and harm staff. Get it right and you can maximize product weights, improve quality, and increase machine speeds. The automatic air conditioning units in the spinning mill system used today is user friendly as well as efficient. Due to this proper and unique control on a process without any interruption of humans. therefore newly developing mill gives prominence to automatic air conditioning plants. Last few years many conditioning companies developing new technologies and systems for textile industries.


Air Conditioning in Spinning Mill


The spinning of yarn from cotton and then weaving or knitting cloth from the yarn is known to mankind millennium. It is probably one of the first crafts developed as men’s thought of civilization, the ancient learned that if the water is sprayed on the floor in hot days or if we get wet cloth is kept over yarn, working is easier because of fewer yarn breakages. This was a state of affairs till 200 years back, but as the industrial revolution takes place mass production was aimed, different methods were developed to provide moisture to the material to the material in the process. As the machine heat added it create a problem to RH%. In the olden days, people are using water cans and more number of windows which may not suitable for high speed.

Another factor is human comfort, if the atmospheric condition in the mill is comfortable to work then it is easy to get maximum efficiency from the worker.


NEED OF RH% CONTROL IN SPINNING:


Correct ambient conditions are essential to prevent degradation of textile material during a series of operations right from beating in blow room to weaving. Yarn should have requisite properties so that the final product retains its basic shape, size & strength.


(When Humidity is High):-


Fiber tends to stick and lead to the formation of laps on rolls that disrupt the production process. Removal of laps is not only a manual and time-consuming process but result in damage to the machine part, especially the rubber material (apron, top roller, etc.).


(When Humidity Is Low ):-


Fiber becomes brittle and store electric charges generated because of friction between the fiber during their spinning process, which affects fiber properties and machine too.
In a modern spinning machine designed with high speed which increases in temperature of the mill and affects the process. Whereas, the modern machine has an electronic control panel that requires a specific temperature. Textile machinery generally is made of steel and aluminum which shows expansion during the process with a different rate which generates thermal and mechanical stress in machines.
Hence along with maintenance of stable RH% condition, recommended for textile and also to maintain the temperature level within range.


GENERAL REASONS FOR RH% AND TEMPERATURE CONTROL:-


  • Dry air causes low regain, yarn with low moisture content are weaker thinner, more brittle & less elastic, and prone to generate a static charge.
  • The material at optimum regain has controlled properties, lower imperfections, more uniform yarn.
  • Higher humidity reduces static problems and machines can run at a higher speed.
  • Textile weight is standardized at 60% RH and 20degree C, low humidity causes lower material weight and less profit.
  • Humidification reduces fly and micro dust, giving a healthier and more comfortable working environment


Conclusion:-


There are many different issues involved with the humidification of the textile plant and as above described in discussions, getting it wrong can be an expensive mistake. So to control process, production, quality, comfort conditioning of air is necessary, even though the humidification plant consumes 15% of the energy of the total spinning plant. That 15% cost can be overcome by improving the quality and production of yarn. In proper conditioning, it is to work and control the production. As an above-mentioned condition of RH% and temperatures for that specific process gives good efficiency and less machine maintenance. Air Conditioning in Spinning Mill is very important in the spinning mill.
