Abstract

A compression hosiery garment includes a knit fabric including a first yarn and a second yarn knit in an alternating knit construction and having at least one course of the second yarn for each course of the first yarn. The first yarn includes a covered yarn with an elastic core, such as a soft modulus elastic core, and the second yarn includes an inelastic yarn. The alternating knit construction includes an inverse course shift, where the first yarn is knit with a first course height that is greater than a second course height of the second yarn.

Claims (18)

1 . A compression hosiery garment, comprising:

a knit fabric comprising a first yarn and a second yarn knit in an alternating knit construction comprising at least one course of the second yarn for each course of the first yarn, the first yarn comprising a covered yarn having an elastic core, the second yarn comprising an inelastic yarn,

wherein the alternating knit construction comprises an inverse course shift in which the course of the first yarn is looser relative to the course of the second yarn, creating a course offset where the first yarn is knit with a first course height that is greater than a second course height of the second yarn, and wherein the course offset between the first course height and the second course height is between 0.2 millimeters and 0.6 millimeters.

2 . The compression hosiery garment of claim 1 , wherein the elastic core comprises a soft modulus of elasticity elastane core.

3 . The compression hosiery garment of claim 1 , wherein the covered yarn comprises an inelastic sheath over the elastic core.

4 . The compression hosiery garment of claim 1 , wherein at least a portion of the knit fabric comprises a compression value of at least 10 millimeter of mercury (mmHg).

5 . The compression hosiery garment of claim 1 , wherein the compression hosiery garment comprises a knitted leg portion, wherein the leg portion comprises bands of progressive or constant compression zones distributed along a longitudinal length of the leg portion, and wherein the garment comprises a first progressive compression zone of the knit fabric, where a first compression value at a first longitudinal end of the first progressive compression zone is greater than a second compression value at a second, opposite longitudinal end of the first progressive compression zone.

6 . The compression hosiery garment of claim 5 , further comprising a first constant compression zone adjacent to the second longitudinal end of the first progressive compression zone, wherein a compression value of the first constant compression zone is generally constant throughout the first constant compression zone, and the compression value of the first constant compression zone is the same as the second compression value of the second longitudinal end of the first progressive compression zone.

7 . The compression hosiery garment of claim 6 , further comprising a second progressive compression zone, a second constant compression zone, and a third constant compression zone;

where the first constant compression zone is positioned at an upper thigh area of the garment, the first progressive compression zone is positioned at a lower thigh area of the garment, the second constant compression zone is positioned at a knee area of the garment, the second progressive compression zone is positioned at a lower leg area of the garment, and the third constant compression zone is positioned at a foot of the garment.

8 . The compression hosiery garment of claim 1 , wherein the knit fabric excludes an in-laid weft yarn.

9 . The compression hosiery garment of claim 2 , wherein the covered yarn comprises an inelastic sheath over the elastic core.

10 . The compression hosiery garment of claim 9 , wherein the compression hosiery garment comprises a knitted leg portion, wherein the leg portion comprises bands of progressive or constant compression zones distributed along a longitudinal length of the leg portion, and wherein the garment comprises a first progressive compression zone of the knit fabric, where a first compression value at a first longitudinal end of the first progressive compression zone is greater than a second compression value at a second, opposite longitudinal end of the first progressive compression zone.

11 . The compression hosiery garment of claim 3 , wherein the inelastic sheath comprises one, two, or more inelastic wrapping fibers over the elastic core.

12 . The compression hosiery garment of claim 5 , wherein the compression value of the first progressive compression zone gradually decreases from the first longitudinal end to the second longitudinal end.

13 . The compression hosiery garment of claim 12 , further comprising a first constant compression zone adjacent to the second longitudinal end of the first progressive compression zone, wherein a compression value of the first constant compression zone is generally constant throughout the first constant compression zone, and the compression value of the first constant compression zone is the same as the second compression value of the second longitudinal end of the first progressive compression zone.

14 . The compression hosiery garment of claim 1 , wherein the knit fabric comprises a level of transparency between 15 Denier and 50 Denier.

15 . The compression hosiery garment of claim 4 , wherein the knit fabric comprises a level of transparency between 15 Denier and 50 Denier.
