A parasitic Acari barrier fabric that impedes parasitic Acari movement, traps parasitic Acari, and/or exterminates parasitic Acari thereon or therein. The barrier fabric includes an outer face formed from open mesh construction having evenly spaced openings formed thereon that are adapted for passing parasitic Acari from outside the fabric to inside the fabric, an inner face that is breathable and configured for moisture vapor transmission from a wearer's skin therethrough but is impenetrable to parasitic Acari passed to the inside of the fabric, and an intermediate spacer that extends between and interconnects the inner face to the outer face to form the parasitic Acari barrier fabric.

A knitted fabric, a method of producing the knitted fabric and a warp knitting machine. The knitted fabric includes a first covering layer; a second covering layer; and an arrangement of pile threads formed as spacer threads between the first covering layer and the second covering layer. Each covering layer includes multiple stitch rows arranged one after another. The spacer threads have different lengths, and the spacer threads woven into each stitch row have equal lengths. The spacer threads in a first width region have a different length than the spacer threads in a second width region. For at least two adjacent stitch rows, one stitch row is connected to spacer threads of a first length in the first width region and one stitch row is connected to spacer threads of a second length in the second width region.

A process for production of knitted articles is disclosed. The process may be performed using, for example, a linear knitting machine including a first needle bed, a second needle bed, a first jacquard bar with odd thread guides, a second jacquard bar with even thread guides, a third jacquard bar with odd thread guides, and a fourth jacquard bar with even thread guides. The process includes producing at least a portion of a knitted article by means of a base movement of the jacquard bars, in which: the first and the third jacquard bar are each moved with an identical shog movement; the second and the fourth jacquard bar are moved with a respective shog movement identical to one another; and the second and the fourth jacquard bar are moved with a respective shog movement identical to one another.
