Description

  The present invention relates to an apparatus and a method for knitting a spacer fabric performed using a circular knitting machine. The present invention further relates to a hooked knitting tool used in this method and a spacer fabric obtained by the method.

  The “spacer fabric” is a knitted fabric in which a cylinder knitted fabric knitted by cylinder needles and a dial knitted fabric knitted by dial needles are joined together by binding yarns, also known as “cardboard knit”. Also called.

  Spacer fabric is excellent in cushioning, heat retention and water absorption, so it can be applied to industrial materials such as vehicle seats and bedding mats, chair upholstery, and cold clothes for nursing clothes, nursing clothes, etc. Usage is progressing. Under such circumstances, a thick spacer fabric is demanded particularly in industrial materials.

  The thickness of the spacer fabric is determined by the distance between the needle cylinder and the needle dial. Conventionally, a spacer fabric manufactured by a circular knitting machine is manufactured by a double knit raceway knitting machine, and a binding yarn is inserted into both a cylinder needle and a dial needle and is tuck-connected. At that time, it is necessary for the cylinder needle to take in the binding thread on the dial needle, but the cylinder needle can only be lifted to the tack position, and accordingly, the distance between the needle cylinder and the needle dial is increased accordingly. I have to shorten it.

  In order to produce a thick spacer fabric in the conventional manner, it is necessary to increase the needle length. However, the needle length cannot be made longer than a certain value due to strength limitations, and when the needle is lengthened, a longer cam is used and productivity is lowered.

  In order to solve these problems, Patent Document 1 below proposes a spacer fabric that can be tucked without being affected by the needle length or the needle stroke.

According to the prior invention, a pile yarn transfer device is disposed between two needle beds of a circular knitting machine. This transfer device has two groups of feed elements, which can each move from an idle position to a tack position. One group of feed elements moves toward the needle hook of the first needle bed, and the other group of feed elements moves towards the needle hook of the other needle bed, bringing the spacer fabric onto the circular knitting machine. Can be manufactured. According to the present invention, a spacer fabric having a thickness of 14 mm or more can be obtained even when a latch needle having a standard dimension of a needle stroke of less than 14 mm is used.
