Patent GB-568150-A (GB)
Title: Coating of synthetic linear polyamide filaments and bristles with polymers of olefine oxides
IPC: D06M15/55
Filed: 1943-07-05
Abstract: Filaments of synthetic polyamides for use as bristles for brushes are coated with a polymer of an olefine oxide.  The coated filaments are more readily formed into tufts of bristles for insertion in the brush back, since the natural smoothness of the filaments is reduced and there is less tendency for the filaments to slip out of place and across each other when they are being taken up by the picker of the brush-making machine.  The filaments or bristles may be immersed in a solution of the olefine oxide polymer which is then drained off, and thereafter the solvent of the adhering solution is evaporated.  The polymer may be a polymer of ethylene oxide which is a water-soluble but non-hygroscopic non-volatile solid of consistency resembling paraffin wax.  A concentration of 1-10 per cent of polymer in the solution may be employed.  In an example, a bundle of nylon bristles fastened together with a rubber band is immersed in an aqueous solution of an ethylene oxide polymer and then centrifuged to remove excess of solution.  The bristles are dried in warm air and held straight during the drying.  They are then fed to the picker of an automatic bristling machine.  Instead of applying the coating to a bundle of bristles, it may be applied to the filaments while they are in the form of continuous strands or in hanks.  If desired, the coating may be removed from the bristles in the manufactured brushes by washing the brushes in water.  Specification 461,236 is referred to.
