Abstract

A knit fabric may be formed by providing a plurality of cylinder needles and a plurality of cutting needles having a cutting surface. A first yarn may be fed to the plurality of cylinder and the plurality of cutting needles to form loops during a knitting cycle. A second yarn may be fed to the plurality of cylinder needles during the knitting cycle so that the first yarn and the second yarn having a plated relationship on the plurality of cylinder needles. A pile may be formed on the knit fabric by cutting the loops on the cutting needles with the cutting surface.

Claims (33)

1. A method of forming a cut pile fabric, the method comprising:

providing a plurality of cylinder needles on a knitting machine cylinder and a plurality of cutting needles on a knitting machine dial, each of the plurality of cutting needles having a cutting surface;

feeding a first yarn to the plurality of cylinder and cutting needles during a knitting cycle to form first loops on the plurality of cylinder needles and second loops on the plurality of cutting needles;

feeding a second yarn to the plurality of cylinder needles;

forming plated loops on the plurality of cylinder needles with the first and second yarns during a single stage of the knitting cycle; and

forming a pile on the knit fabric by cutting the first loops on the plurality of cutting needles with the cutting surfaces to form cut loop ends, the plated loops holding the cut loop ends in the knit fabric to form the pile.

2. The method of claim 1 , wherein the step of forming the plated loops further comprises:

holding the plurality of cutting needles stationary during the knitting cycle as the plurality of cylinder needles receives the second yarn to form the plated loops.

3. The method of claim 1 , wherein the cotton count of the first yarn is greater than the cotton count of the second yarn.

4. The method of claim 1 , wherein the first yarn is selected from the group comprising a ring-spun yarn, an open-end yarn, an air-jet spun yarn, and a continuous filament yarn.

5. The method of claim 1 , wherein the second yarn is selected from the group comprising a ring-spun yarn, an open-end yarn, an air-jet spun yarn, and a continuous filament yarn.

6. A method of forming a cut pile knit fabric, the method comprising:

providing a plurality of cylinder needles on a knitting machine cylinder and a plurality of cutting needles on a knitting machine dial, each of the plurality of cutting needles having a cutting surface;

feeding a first yarn to the plurality of cylinder and cutting needles during a knitting cycle to form first loops on the plurality of cylinder needles and second loops on the plurality of cutting needles;

feeding a second yarn to the plurality of cylinder needles;

forming plated loops on the plurality of cylinder needles with the first and second yarns during a single stage of the knitting cycle;

holding the plurality of cutting needles stationary during the knitting cycle as the plurality of cylinder needles receives the second yarn to form the plated loops; and

forming a pile on the knit fabric by cutting the first loops on the plurality of cutting needles with the cutting surfaces to form cut loop ends, the plated loops holding the cut loop ends in the knit fabric to form the pile.

7. The method of claim 6 , wherein the cotton count of the first yarn is greater than the cotton count of the second yarn.

8. The method of claim 6 , wherein the first yarn is selected from the group comprising a ring-spun yarn, an open-end yarn, an air-jet spun yarn, and a continuous filament yarn.

9. The method of claim 6 , wherein the second yarn is selected from the group comprising a ring-spun yarn, an open-end yarn, an air-jet spun yarn, and a continuous filament yarn.

10. The method of claim 6 , wherein the knit fabric forms a portion of a garment selected from the group comprising sweatshirts, sweatpants, underwear and outwear.

11. A method of forming a knit fabric, the method comprising:

providing a plurality of cylinder needles on a knitting machine and a plurality of cutting needles on a knitting machine capable of translating across the plurality of cylinder needles, each of the plurality of cutting needles having a cutting surface;

feeding a first yarn to the plurality of cylinder and cutting needles during a knitting cycle to form first loops on the plurality of cylinder needles and second loops on the plurality of cutting needles;

feeding a second yarn to the plurality of cylinder needles;

forming plated loops on the plurality of cylinder needles with the first and second yarns during a single stage of the knitting cycle;

holding the plurality of cutting needles stationary during the knitting cycle so that the plurality of cylinder needles receives the second yarn to form the plated loops; and

forming a pile on the knit fabric by cutting the first loops on the plurality of cutting needles with the cutting surfaces to form cut loop ends, the plated loops holding the cut loop ends in place to form the pile.

12. The method of claim 11 , wherein the knitting machine is a flat v-bed machine.

13. The method of claim 11 , wherein the cotton count of the first yarn is greater than the cotton count of the second yarn.

14. The method of claim 11 , wherein the first yarn is selected from the group comprising a ring-spun yarn, an open-end yarn, an air-jet spun yarn, and a continuous filament yarn.

15. The method of claim 11 , wherein the second yarn is selected from the group comprising a ring-spun yarn, an open-end yarn, an air-jet spun yarn, and a continuous filament yarn.
