Abstract

A method of forming a circular knit fabric includes feeding a multi-filament non-elastomeric yarn from a first spool into an aperture defined in a yarn carrier plate that guides the non-elastomeric yarn sequentially to a series of knitting needles spaced about a circular needle array; while feeding an elastomeric yarn from a second spool to the yarn carrier plate, such that a fabric is knit to have a ground comprising both the non-elastomeric yarn and the elastomeric yarn. The non-elastomeric yarn and the elastomeric yarn are fed together into the carrier plate aperture in an untwisted, unwrapped relation, such that the fabric ground is knit to have a technical face in which portions of the non-elastomeric yarn are exposed in some areas and portions of the elastomeric yarn are exposed in some areas.

Claims (12)

1. A method of forming a circular knit fabric, the method comprising

feeding a multi-filament non-elastomeric yarn from a first spool into an aperture defined in a yarn carrier plate that guides the non-elastomeric yarn sequentially to a series of knitting needles spaced about a circular needle array; while

feeding an elastomeric yarn from a second spool to the yarn carrier plate, such that a fabric is knit to have a ground comprising both the non-elastomeric yarn and the elastomeric yarn;

wherein the non-elastomeric yarn and the elastomeric yarn are fed together into the carrier plate aperture in an untwisted, unwrapped relation, such that the fabric ground is knit to have a technical face in which portions of the non-elastomeric yarn are exposed in some areas and portions of the elastomeric yarn are exposed in some areas.

2. The method of claim 1 , further comprising feeding a pile yarn from a third spool into a pile yarn aperture defined in the carrier plate, such that the pile yarn is delivered to the knitting needles to form a pile extending from a technical back of the knit fabric.

3. The method of claim 1 , wherein the non-elastomeric yarn comprises a texturized yarn.

4. The method of claim 1 , wherein the elastomeric yarn comprises a non-wrapped yarn.

5. The method of claim 1 , further comprising applying a stretchable binder to the knit fabric ground.

6. The method of claim 1 , further comprising adhesively laminating the technical face of the knit ground of the fabric to a technical face of another fabric.

7. The method of claim 6 , wherein the other fabric has a technical face at which elastomeric yarn is present.

8. The method of claim 6 , wherein adhesively laminating the technical face of the knit ground comprises applying a stretchable acrylic adhesive to the technical face of the knit ground.

9. The method of claim 8 , wherein the adhesive is applied to cover no more than about 70 percent of an area of the knit ground.
