Estimating the term…
This invention relates to paper machine clothing and has particular reference to paper machine clothing suitable for use in the forming, presing and drying sections of a papermakng machine and comprises a monofilament and/or staple fibre in which themonofilament or staple fibre comprises a polyamide material which has been subjected to a treatment with an aqueous solution of aldehyde in the presence of a catalyst to effect partial cross-linking of the polyamide to provide a gel content thereof within the range of 0.1-75%.
In an article of paper machine clothing comprising a base fabric having a carded batt of staple fibers needled into an upper layer thereof, said staple fibers comprising a polyamide material, the improvement comprising staple fibers of a polyamide material which have been subjected to a treatment with an aqueous solution of aldehyde in the presence of a catalyst to effect partial cross-linking of the polyamide to provide a gel content thereof within the range of 0.1-75% accompanied by a reduction in crystallinity in the range of 1-65% compared with the uncrosslinked material.
