Abrasion treatments laminates

A large variety of desirable properties for membranes may be provided by the fibres themselves or by their finishing and post-treatment before the production of the fabric. If these do not provide the required properties such as watertightness, dirt and oil repellence, UV protection, flame retar-dance or abrasion resistance, the fabric must be coated or laminated. Additionally an unweldable textile (e.g. PILE) may have a weldable coating applied. 

Surface Preparation. The first step in the imaging operation is surface preparation to enhance photoresist adhesion. Double-treated foils (DTFs) and foils laminated with the tooth side up (RTFs) require minimum surface preparation. Generally, a process through a tacky roller machine to remove dust and foreign material is adequate. For cores with standard foil with the shiny side up (non-tooth or drum side), a more aggressive treatment is needed. Common options include a conveyorized chemical cleaning and/or an abrasive...
