Latest Patents
Donigian holds a patent for a method that provides enhanced smoothness for a paper web. This innovative technique involves wet densifying a paper rawstock web on a papermachine at a moisture content greater than about 20% and less than about 50%. The process utilizes a calender device at nip pressures exceeding 3000 psi, preferably within the range of 3000-6000 psi. This method results in fiber springback resistance and irreversibly smooth surfaces that are resistant to loss of smoothness upon rewetting. The wet densification process produces a web with greater density and increased internal bond strength compared to conventionally treated webs, achieving superior smoothness.
