It is an example of the figure schematically showing the multi-layered woven and knitted fabric of the present invention.

Hereinafter, embodiments of the present invention will be described in detail. The present invention is a multi-layered woven knit including a connecting yarn connecting the front and back ground texture portions, the front and back ground texture portions, and an insertion yarn, and the front yarn and the connecting yarn are water-repellent fibers (“water-repellent yarn”). It is also composed of.). FIG. 4 schematically shows it.

In the present invention, the outside air side is referred to as a front ground tissue portion, and the yarn arranged on the front ground tissue portion is referred to as a front yarn. On the contrary, the skin side is referred to as the back ground tissue portion, and the thread arranged on the back ground tissue portion is referred to as the back thread.

It is preferable that at least one of the front yarn and the back yarn has a torque of 30 T / m or less.
Here, at least one of the front yarn and the back yarn is a composite including 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 thread.

The false twist crimped yarn has a so-called one heater false twist crimped yarn in which false twist is set in the first heater region, and the yarn is further introduced into the second heater region to perform relaxation heat treatment to reduce torque. There is also a so-called second heater false twist crimped yarn. Further, depending on the twisting direction, 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, it is preferable to form a composite yarn with 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, because a low torque composite yarn can be obtained.

The composite yarn can be produced, for example, by the following method. That is, one heater false twist crimped yarn is obtained by twisting the yarn with a twisting device via a first roller and a heat treatment heater having a set temperature of 90 to 220 ° C (more preferably 100 to 190 ° C). It may be obtained, or if necessary, it may be further introduced into the second heater region and subjected to relaxation heat treatment to obtain a second heater false twist crimped yarn. The draw ratio during false twist processing is preferably in the range of 0.8 to 1.5, and the false twist number is in the formula of false twist number (T / m) = (32500 / (Dtex) 1/2) × α. α = 0.5 to 1.5 is preferable, and usually 0.8 to 1.2 is preferable. However, Dtex is the total fineness of the yarn. As the twisting device to be used, a disc type or belt type friction type twisting device is suitable because it is easy to thread and has less thread breakage, but a pin type twisting device may be used. Further, depending on the twisting direction, the torque of the false twist crimped yarn can be selected from the S direction and the Z direction. Next, the composite yarn is obtained by combining two or more types of false twist crimped yarns.

It is preferable that the composite yarn is entangled by interlacing. The number of entanglements (interlaces) is preferably in the range of 1 to 70 / m so as not to impair the soft texture and stretchability. If the number is larger than 70 / m, the soft texture and stretchability may be impaired. On the contrary, if the number is smaller than 1 piece / m, the focusing property of the composite yarn becomes insufficient, and the knitting property and the weaving property may be impaired. The entanglement processing (interlacing processing) may be performed using a normal interlacing nozzle. The number of entanglements is measured by the following method. That is, the entangled yarn was taken to a length of 1 m under a load of 8.82 mN × display tex (0.1 g / de), and after weight removal, the number of nodal points after 24 o'clock discharge at room temperature was read, and the number of pieces / Display with m.

In the composite yarn thus obtained, the smaller the torque, the more preferable, and the non-torque (0 T / m) is most preferable. In order to obtain non-torque in this way, when the false twist 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 torque directions are different. It is advisable to use two types of false twist crimped yarn.
