Print coating

Stiffness of the films and sheeting can be measured as the tensile modulus of elasticity. Droop or drape tests may be used, particularly for multilayer products. The stiffness is strongly influenced by thickness (to the third power) and temperature, and is important to the processing of film in printing, coating, or end use appHcations where it affects the "hand" of the product. 

Solvent Recovery. Most of the activated carbon used in gas-phase applications is employed to prevent the release of volatile organic compounds into the atmosphere. Much of this use has been in response to environmental regulations, but recovery and recycling of solvents from a range of industrial processes such as printing, coating, and extmsion of fibers also provides substantial economic benefits. 

The US Environmental Protection Agency recently announced its intention to develop and implement new Clean Air Act Standards for industrial coatings operations within the next year. These emission standards will eventually require companies involved in fabric printing, coating and dyeing operations to comply with Maximum Achievable Control standards. The Hazardous Air Pollutants emission limits that will apply to facilities and the impact on fabric coating operations are discussed. USA...

In smart polymer applications in textiles, PCMs and colour change polymers mostly take the form of microcapsules. A microcapsule is an intermediate state which is added to solutions, fibres, films and nonwovens to incorporated a smart function into the textile. These materials may be incorpated into textiles by printing, coating and dyeing. For printing and coating, the materials are microencapsulated first and then coated or printed onto the fabric surface by common methods such as the pad-dry-cure process.
