Abstract: A circular knitting machine includes sinkers and selector jacks corresponding thereto that are provided as separate components. The selector jacks are arranged radially outside the sinkers, and are provided with selector butts such that the selector butts of circumferentially adjacent selector jacks are arranged at different radial positions. An actuator that acts on the selector butts is arranged radially outside the cylinder. The circular knitting machine prevents a failure of sinker selection, while increasing a rotation speed of a cylinder holding knitting needles.

Abstract: A knitting machine capable of changing a pile length includes a low-pile sinker and a high-pile sinker, a low-pile selector jack arranged on the rear end side of the low-pile sinker, a high-pile selector jack arranged on the rear end side of the high-pile sinker, an actuator operable to, when a pile yarn and a ground yarn are drawn in by a knitting needle, selectively perform the first control in which the actuator acts on the low-pile selector jack, the second control in which the actuator acts on the high-pile selector jack, and the third control in which the actuator does not act on any of the low-pile and high-pile selector jacks, and a cam operable to push out the selector jack subjected to the action of the actuator and the sinker which is in contact with the selector jack to an area between the knitting needles.

Abstract: A knit product includes a compression region and is formed by a circular knitting machine knitting first and second stitches having different stitch sizes in the same course. The second stitch has a smaller stitch size. The second stitch is selectively provided on a stitch-by-stitch basis. The knitting needles have a density of 14 to 24 per inch in a circumferential direction. A face yarn of a knitting yarn has a cotton count larger than 10. A back yarn of the knitting yarn is a covering yarn having a core yarn of polyurethane of 70 denier or less or a man-made fiber of 140 denier or less subjected to texturing. The size difference between the first and second stitches is 0.1 mm to 2.0 mm. The elongation difference between a first-stitch region of the first stitch and a second-stitch region of the second stitch is 20% to 100%.
