A method of improving the outer portion of a rotatable textile fiber processing component is provided, the method comprising the steps of making the outer portion substantially of butadiene copolymer rubber, subjecting the outer portion to the action of a halogen to define the desired properties of minimum compression set for the outer portion and a working surface which has a comparatively low coefficient of friction, mounting the component on a rotatable support means of a textile processing equipment, then operating the equipment whereby the outer portion of the component is worked, and applying additional halogen on the outer portion with the component in a stationary position in its working environment in the equipment while supported on the rotatable support means therefor after the outer portion has been worn from the working thereof whereby the outer portion is rejuvenated so that further operation of the equipment can take place with the component again having the desired properties.
