<p>A drum cladding material, contg. at least a portion of glass fibres in its construction, is used to cover a mesh drum used in the processing of web materials. This is the case where there is a requirement for a gas or fluid to pass through fabrics made wholly or partially of synthetic fibres, feltings of loose fibres, paper, etc. The drum cladding material can withstand high process temps. and leave no marks on the material being processed as it will not accept any dyestuffs from the fabrics passing through.</p> |
