Open the CIPO recordAbstract From the Canadian patent
An improved textile dryer has a dryer fabric for transporting a textile through at least one through-air drying zone. The fabric is woven from synthetic monofilament yarns. The monofilament yarn dimensions and fabric weave pattern are selected to provide permeability greater than 900 CFM and initial tensile strength measured in the machine direction of greater than about 100 PLI. The monofilament yarns are formed from polymers which provide high thermal and hydrolytic stability thereby enabling the dryer fabric to maintain strength for extended use in the textile drying environment. Preferred monofilament yarns are made of unalloyed polyphenylene sulfide.

Why it's free to use
- Filed June 29, 1994 and granted January 19, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 29, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 29, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
