Abstract
The present invention relates to a process of obtaining an industrial fabric with porous and controlled plasticized surface and an industrial fabric with the mentioned characteristics thereof. The invention also relates to an industrial fabric such as press fabric for use in the press section of a paper machine with enhanced aesthetic properties by the use of plasticizers and optional heat and/or pressure treatment.
Claims20
An industrial fabric with a porous surface, the fabric comprising:
- a support structure formed of a polymeric material;
- wherein a surface of the fabric support structure is treated with a plasticizer sufficient to lower the glass transition temperature of the polymeric material by 40-60° C. such that the use of heat and/or pressure causes fiber flattening and densification, and wherein said plasticizer is washed out of said industrial fabric after fiber flattening and densification.
An industrial fabric with a porous surface, the fabric comprising:
- a support structure formed of a polymeric material;
- wherein a surface of the fabric support structure is treated with a plasticizer sufficient to lower the glass transition temperature of the polymeric material by 40-60° C. such that fiber deformation is achieved by passing the fabric over and around a roll, with or without pressure and/or heat, and wherein said plasticizer is washed out of said fabric after said fiber deformation.
An industrial fabric with a porous surface, the fabric comprising:
- a support structure formed of a polymeric material;
- wherein a surface of the fabric support structure is treated with a plasticizer sufficient to lower the glass transition temperature of the polymeric material by 40-60° C. such that fiber-to-fiber bonding is achieved by passing the fabric over and around a roll, with or without pressure and/or heat, and wherein said plasticizer is washed out of said fabric after said fiber-to-fiber bonding.
