Wet press paper making felt

摘要

A method of manufacturing a wet press papermaker's felt fabric, which comprises: assembling the fibrous textile components of a wet press fabric and a solvent-removable material into the form of a wet press fabric; compacting the formed fabric to increase the overall density of the fabric; and dissolving the solvent removable material; whereby voids are formed in the fabric where the solvent removable material is dissolved. DEAB- DE3419708 C Mfr. of a wet press felt for paper machines involves needling at least one nonwoven layer on one side or both sides of a base fabric. Detachable material contained in the needled prod. after the needling process is removed by means of a solvent. The nonwoven consists of fibres and particles soluble by means of a solvent and of solvent-resistant fibres and is needled on the base fabric. The needled prod. is compressed and the soluble material removed. The base fabric can consists of polyamide yarns.
