Abstract
A method of manufacturing and a papermaker's or industrial fabric, which includes the application of a polymeric resin material onto preselected discrete locations on a base substrate in a controlled manner in droplets having an average diameter of 10μ (10 microns) to point bond yarns, bond spiral wound strips together or to bond layers of a fabric together.
Claims23
A method for manufacturing a papermaker's or industrial fabric, said method comprising the steps of:
- a) providing a base substrate for the fabric having yarns that crossover one another at discrete crossover locations in a woven or nonwoven pattern;
- b) depositing a plurality of polymeric resin material droplets on said base substrate at a plurality of preselected discrete crossover locations in a controlled manner so as to control the lengthwise and widthwise dimensions as well as the amount of polymeric material deposited thereby bonding said yarns together at said discrete crossover locations so as to provide dimensional stability to said fabric;
- and
- c) at least partially setting said polymeric resin material droplets.
A papermaker's or industrial fabric comprising:
- a base substrate having yarns that crossover one another at discrete crossover locations in a woven or nonwoven pattern;
- and
- a plurality of discrete dimensionally controlled deposits comprised of one or more polymeric resin material droplets at preselected crossover locations, said dimensionally controlled deposits having widthwise and lengthwise dimensions defined by the controlled placement of said droplets, wherein said polymeric resin material droplets bond said yarns together at said discrete crossover locations so as to provide dimensional stability to said fabric.
A method for manufacturing a papermaker's or industrial fabric, said method comprising the steps of:
- a) providing a base substrate for the fabric having yarns that crossover one another at discrete locations in a woven or nonwoven pattern;
- or includes strips of material wound in adjacent turns where the strips abut one another with a lateral fringe overlap with yarns of an adjacent strip to provide a plurality of discrete locations;
- or includes an MD or CD yarn array which are to be bonded together at discrete locations,
- b) depositing a plurality of polymeric resin material droplets on said base substrate at a plurality of preselected discrete locations in a controlled manner so as to control the lengthwise and widthwise dimensions as well as the amount of polymeric material deposited thereby bonding said yarns together at said discrete locations so as to provide dimensional stability to said fabric;
- and
- c) at least partially setting said polymeric resin material droplets.

- or includes an MD or CD yarn array which are to be bonded together at discrete locations;
- and
- a plurality of discrete dimensionally controlled deposits comprising one or more polymeric resin material droplets at preselected locations, said dimensionally controlled deposits having widthwise and lengthwise dimensions defined by the controlled placement of said droplets, wherein said polymeric resin material droplets bond said yarns together at said discrete locations so as to provide dimensional stability to said fabric.
