A tubular knit fabric is disclosed that is manufactured with a pile extending from the outer side thereof and in an extended length, small diameter configuration, the tubular knit pile fabric subsequently being separable into shorter tubular segments that may be secured to paint roller cover cores to produce seamless paint rollers. The knit paint roller cover fabric of the present invention is manufactured in a tubular segment with cut pile segments extending from the outside of the tubular knit paint roller cover fabric. The tubular knit paint roller cover fabric of the present invention is also manufactured in a size that makes it appropriate for installation onto paint roller cover cores.

A knit pile fabric as defined in claim 1, wherein said base fabric and said pile are knitted from yarns made of natural or synthetic yarn fibers, or a blend of natural and synthetic fibers. 3. A knit pile fabric as defined in claim 2, wherein said yarns have a denier of between seventy-five and one thousand five hundred. 4. A knit pile fabric as defined in claim 2, wherein the yarn used for said base fabric is made of wool, polyester, acrylic, polypropylene, aramid, spandex, or a blend of any of the aforementioned. 5. A knit pile fabric as defined in claim 2, wherein the yarn used for said cut pile segments is made of wool, polyester, acrylic, nylon, modacrylic, rayon, polypropylene, aramid, or a blend of any of the aforementioned. 6. A knit pile fabric as defined in claim 1, wherein said cut pile segments have a pile height of between approximately one-quarter inch and approximately three inches. 7. A knit pile fabric as defined in claim 1, wherein the number of wales in said tubular configuration base fabric is between approximately forty and approximately one hundred. 8. A knit pile fabric as defined in claim 7, wherein the number of wales in said tubular configuration base fabric is approximately fifty-six. 9. A knit pile fabric as defined in claim 1, wherein said tubular configuration base fabric has an inner diameter of approximately five inches or less. 10. A knit pile fabric as defined in claim 9, wherein said tubular configuration base fabric has an inner diameter that is approximately the same size as the outer diameter of a paint roller cover core. 11. A knit pile fabric as defined in claim 10, wherein said tubular configuration base fabric has an inner diameter of approximately one and one-half inches. 12. A knit pile fabric as defined in claim 1, wherein said tubular configuration base fabric is manufactured in an extended length that is substantially longer than the length of a paint roller. 13. A paint roller cover made in part from a knit pile fabric as defined in claim 1, said paint roller cover comprising: a hollow cylindrical paint roller cover core; and a segment of said tubular configuration base fabric secured to the outside surface of said paint roller cover core. 14. A paint roller cover as defined in claim 13, wherein said tubular configuration base fabric is secured to the outside surface of said paint roller cover core using an adhesive. 15. A paint roller cover as defined in claim 13, wherein said tubular configuration base fabric is combed and sheared to the desired length after said segment of said tubular configuration base fabric is secured to the outside surface of said paint roller cover core. 16. A paint roller cover as defined in claim 15, wherein said tubular configuration base fabric is also beveled and vacuumed after said segment of said tubular configuration base fabric is secured to the outside surface of said paint roller cover core. 17. A knit pile fabric suitable for use on paint roller covers, said knit pile fabric comprising: an uninverted knitted base fabric having a tubular configuration defining an outside and an inside, said base fabric having wales located adjacent each other and arranged around the circumference of said base fabric, said base fabric also having successive courses each of which is knit after a preceding course, said base fabric comprising a plurality of loops, wherein each loop in any particular wale is knitted through a loop in the preceding course in said particular wale; and a plurality of cut pile segments, each of said cut pile segments being knitted together with a loop of said base fabric into said base fabric with the ends of said cut pile segments extending outwardly from said base fabric and forming the pile of said knit fabric. 18. A knit pile fabric suitable for use on paint roller covers, said knit pile fabric comprising: an uninverted knitted base fabric having a tubular configuration defining an outside and an inside, said base fabric having between forty and one hundred wales located adjacent each other and arranged around the circumference of said base fabric, said base fabric having successive courses each of which is knit after a preceding course, said base fabric comprising a plurality of loops, wherein each loop in any particular wale is knitted through a loop in the preceding course in said particular wale from the outside to the inside of said tubular configuration of said base fabric; wherein said tubular configuration base fabric has an inner diameter that is approximately the same size as the outer diameter of a paint roller cover core; and a plurality of cut pile segments, each of said cut pile segments having opposite ends with a loop portion located therebetween, said loop portion of each of said plurality of cut pile segments being knitted together with a loop of said base fabric into said base fabric, said opposite ends of said plurality of cut pile segments extending outwardly from said base fabric and forming the pile of said knit fabric, wherein said cut pile segments have a pile height of between approximately one-quarter inch and approximately three inches. 19. A method of making a knit pile fabric comprising: knitting a base fabric in a tubular configuration defining an outside and an inside, said base fabric having a predetermined number of wales located adjacent each other and arranged around the circumference of said base fabric, said base fabric having successive courses each of which is knit after a preceding course, said base fabric comprising a plurality of loops, wherein each loop in any particular wale is knitted through a loop in the preceding course in said particular wale from the outside to the inside of said tubular configuration of said base fabric; providing a plurality of cut pile segments, each of said cut pile segments having opposite ends with a loop portion located therebetween; and knitting said loop portion of each of said cut pile segments together with a loop of said base fabric into said base fabric, said opposite ends of said plurality of cut pile segments extending outwardly from said base fabric and forming the pile of said knit fabric. 20. A method as defined in claim 19, wherein said base fabric and said pile are knitted from yarns made of natural or synthetic yarn fibers, or a blend of natural and synthetic fibers. 21. A method as defined in claim 20, wherein said yarns have a denier of between seventy-five and one thousand five hundred. 22.
