  Hereinafter, embodiments of the present invention will be described in detail. The present invention is a multi-layer structured woven or knitted fabric including a front and back ground tissue portion, a tie yarn connecting the front and back ground tissue portions, and an insertion yarn, wherein the front yarn and the tie yarn are water repellent fibers ("water repellent yarn" It is also composed of It is schematically shown in FIG.

  In the present invention, the outside air side is referred to as the front texture portion, and the yarn arranged in the front texture portion is referred to as the front yarn. On the contrary, the skin side is defined as the back ground texture portion, and the yarn arranged in the back ground texture portion is referred to as the back yarn.

It is preferable that at least one of the front and back yarns has a torque of 30 T / m or less.
Here, a composite in which at least one of the front yarn and the back yarn includes a false twist crimped yarn A having a torque in the S direction and a false twist crimped yarn B having a torque in the Z direction. It is preferably a yarn.

  A so-called one heater false-twist crimped yarn in which false twist is set in the first heater zone for the false-twist crimped yarn, and the yarn is further introduced into the second heater zone and subjected to relaxation heat treatment to reduce torque In addition, there is a so-called second heater false twist crimped yarn. Further, depending on the direction of twisting, there are a false twist crimped yarn having a torque in the S direction and a false twist crimped yarn having a torque in the Z direction. In the present invention, these false twist crimped yarns can be used. In particular, when a composite yarn is constituted by a false twist crimped yarn having a torque in the S direction and a false twist crimped yarn having a torque in the Z direction, a low torque composite yarn is obtained, which is preferable.

  The composite yarn can be produced, for example, by the following method. That is, one heater false crimped yarn is obtained by twisting the yarn with a twisting device via a first roller, a heat treatment heater having a set temperature of 90 to 220 ° C. (more preferably 100 to 190 ° C.)

That is, the length of the entangled yarn was 1 m under a load of 8.82 mN × display tex (0.1 g / de), and after dewetting, the number of knot points after 24 hours contraction at room temperature was read. Display with m.

  In the composite yarn thus obtained, the torque is preferably as small as possible, and the non-torque (0 T / m) is most preferable. In order to achieve non-torque in this way, when the false twisted crimped yarn having the torque in the S direction and the false twisted crimped yarn in the Z direction are combined, they have the same torque except that the direction of the torque is different. It is good to use two kinds of false twist crimped yarns.
