ABSTRACT:
An improved finishing treatment for pile carpets is described. The improvement lies in providing a method and apparatus for producing a controlled manner, uniform and unidirection pile lean, and to stabilize the pile lean with that orientation to restrict reversal of the pile lean during actual use of the carpet on the floor. One method of the invention is to transport the pile carpet past a pre-orientation brush or roller, through a pair of compression rollers that cause the pile to lean in the trailing direction whilst subjecting the pile to a compression cycle. The improved treatment may be applied to both cut and loop pile carpets and may find application in carpet manufacture, making the carpet resistant to pile reversal in use and reducing the propensity of the carpet to shade in an objectionable manner.
