Chemical Finishes

Albarrie provides various chemical finishes to their manufactured fabrics.

Depending on customer requirements and facility processes the chemical finish will vary. These chemical finishes are applied by a proprietary process, during which a fabric is fully immersed in a chemical solution and dried. Additional curing contributes to improved durability of the chemical finishes. When the body of the fabric is saturated in a chemical solution each individual fiber filament becomes fully coated and encapsulated by a layer of polymer.

Albarrie's highly advanced technology produces fabrics which possess outstanding performance and durability, unsurpassed by any competitive product.

Albarrie Filtration Fabrics are treated to:

• Improve filterability
• Reduce pressure drop
• Increase mechanical durability
• Provide better cleanability
• Provide better chemical resistance
• Prolong service life

 

Finish	How they work	Recommendations
Antistatic	Improves conductivity of fibers Coats fiber with thin layer of material that will attract a thin layer of moisture Fabric holds a charge opposite to that normally accumulated to neutralize the static charge	Polyester fabric Typical for light polymer powders
Water Repellent	Fibers are treated evenly to provide the lowest critical surface tension Main purpose is to prevent bags from blinding caused by accumulation of wet, sticky or agglomerating dust	All filtration systems where moisture in the flue gas is present Drying processes, food processing and combustion processes
Water and Oil Repellent	Provides a durable, clear protective barrier Characterized by extremely low surface tension, which is lower than that of oils	Any industrial facility which burns any type of a fossil fuel i.e.; cement plants, refuse systems and incinerators
Acid Resistant	Imparts hydrophobic and oleophobic properties Improves abrasion resistance of fabrics Improvement of bag life by stopping the acid degradation process Polymer systems encapsulate all individual filaments protecting them from chemical attack	Wood burning processes Processes in metallurgical industries where significant quantities of hydrocarbons can be drawn to the filtration system when rolled steel is coated with rust protecting oils
