A method of making a loop fastener product features knitting, such as by circular knitting, a pile yarn and one or more ground yarns to form a stretchable knit fabric having loops of the pile yarn extending from a knit ground, with the ground yarns including polymers of differing melt temperatures. The knit fabric is then held in a desired state while the fabric is set by first applying sufficient heat to cause the lower melt temperature resin to flow into interstices of the fabric ground, and then allowing the fabric to cool. The cooled fabric ground is less stretchable in two orthogonal directions after setting than before setting, has a greater air permeability after setting than before setting, and has hook-engageable pile loops extending from bound interstices.

A process for manufacturing a tubular knitted item (1) with intarsia design, comprising the steps of: programming a circular weft knitting machine for intarsia design by defining a tubular intarsia knitted item (1) to be manufactured, extending longitudinally between a first end (2) and a second end (3) and consisting of a plurality of knitted courses following one another;
wherein the programming step comprises the steps of: defining a turning position (4), which divides the tubular item into a first fabric (5) and a second fabric (6), wherein the tubular item is configured for being manipulated so as to be at least partially turned over itself, by folding it in the turning position so that the second fabric overlaps the first fabric in order to obtain a double fabric item; defining at least one first area (10) of the first fabric, delimited by a needle section and by a number of successive courses of the area, and having a desired shape; defining at least one first counter-area (20) of the second fabric, delimited by a needle section and by a number of successive courses of the area, in which the first counter-area has a respective shape; producing intarsia knitted fabric so as to manufacture the tubular knitted item according to the programming step; wherein the first area (10) is manufactured according to a first knitted structure and the first counter-area (20) is manufactured according to a second knitted structure.

A circular knitting machine for manufacturing open-work knitted fabric includes a crown arranged around a needle-holding cylinder and having a plurality of radial grooves and a guiding ring operatively associated to the crown. Each of a plurality of knockover sinkers is housed in one of the radial grooves, is radially movable in the respective radial groove and has a pin configured for cooperating with the needles. At least one shaped sinker is placed beside each of the knockover sinkers and is movable with respect to the respective knockover sinker. The shaped sinker has a protrusion offset laterally with respect to the respective knockover sinker and configured for elongating an interstitch, arranging it on an adjacent needle and forming an open work. A selector is operatively coupled with the shaped sinker and is oscillating in a radial plane between a rest position and an operating position, wherein in the operating position the selector acts indirectly upon the shaped sinker so as to deviate the trajectory of the shaped sinker. A selecting actuator faces laterally the crown and can be engaged upon command with the selectors for causing the selectors to switch from the rest position to the operating position.
