Resilient cotton fiber and related method |
(57) An improved fiber product comprises individual fibers which are finish-treated by
saturating the fibers in a finish solution of durable press resin and a lubricant,
then drying and curing the fibers such that the resin is saturated and cured and cross-linked
to the interior of the fibers while the lubricant is maintained at or near the surface
of the fibers. A preferred method includes treating bleached cotton fibers with a
finish solution containing 3.0% - 4.0% of a formaldehyde-free, alkylated glyoxyl/cyclic
urea condensate resin and 1.5% -2.5% of a reactive silicone, and a catalyst. The resultant
finish-treated cotton fibers have a resiliency greater than untreated fibers and comparable
to or greater than polyester fibers.
