Most sports goods like gloves, wickets, hockey sticks, carrom boards, chess boards and various types of balls eg. golf, cricket, hockey and of course, the football, etc. are made of hygroscopic material like wood and leather. 

When exposed to high relative humidity, these materials absorb moisture which leads to shrinkage or “bloating” of the product as well as increased microbial activity resulting in defective finished product. 

Thus, it is essential to keep humidity under control in the area where finished sports goods are manufactured as well as stored.


Cricket bats are made from willow, which is a soft fibrous wood and is highly hygroscopic and tends to absorb moisture from the surrounding air during manufacturing and storage. The moisture tends to make the wood shrink/ contract and expand when the moisture content changes with the relative humidity of the surrounding air, thus affecting the final quality of the bat.


Protective gears like gloves, shin and shoulder pads are made of polyurethane, which absorbs and reacts with moisture very rapidly. This degrades the material,which results in defects in the products.


Leather, being hygroscopic, adsorbs moisture during processing, paclaging and storage which results in increased microbial activity, This results in the leather balls losing their gloss and ending up with a dull finish, leading to rejection of the final product.


Golf balls are made of thermoplastic ionomers or themoset polyurethane. These materials are susceptible to moisture intake during the manufacturing process, and must be kept in humidity controlled area.


Uncontrolled humidity in the football production and storage rooms causes growth of fungus, mold and milde. This leads to decomposition of the footballs, thus spoiling the sheen of the finished products To prevent this spoilage, It is necessary to maintain RH at less then 40% in the footba;; production and storage rooms


The ideal way to maintain the required Bry-Air conditions for manufacturing and storage of sports equipment is to maintain humidity levels at less then 40%RH during the manufacturing process and storage. The simplest and most cost effective way of controlling humidity is through Desiccant Dehumidification. Bry-Air Dehumidifiers ensures removal of excess moisture from the air inside the storage and packaging areas by continuously circulating dry air, thus maintaining relative humidity at less than 40%. This prevents the material from regaining moisture, thereby arresting fungal growth and ensuring perfect quality of the finished goods.



Case Study:
M/s Mayor & Co.
(Established in 1961)
Jalandhar, Punjab
Industry: Sports Goods

Mayor & Co. is one of the prestigious manufacturers and exporters of sports goods with a history of over 50 years. One of their major concerns was fungal growth on their footballs while shipping them to European countries. The football panels are made of PU and latex is used as an adhesive for pasting the cotton on the panels. The sewing of the panels was outsourced. During monsoon, the footballs were affected by fungal growth by the time they reached the clients, which led to rejection of the consignments. Called in to provide a solution the Airgineers from Bry-Air, discovered that there was fungal growth in the seams of the footballs due to uncontrolled levels of humidity during packaging. Mayor was advised to install a Bry-Air Compact Dehumidifier to maintain RH below 40% at a temperature of 27°C. It was also recommended an AC be installed for the comfort of the people working in the final packaging room. Mayor has been able to get rid of the fungal growth problem effectively.
