Next, preferred embodiments of the present invention will be described by way of the examples with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view of a composite waterproof and breathable tabi according to the present invention. FIG. 2 is an enlarged cross-sectional view of region II of the composite waterproof and breathable tabi of FIG. FIG. 3 is an enlarged cross-sectional view of region III of the composite waterproof and breathable tabi of FIG.

Referring to FIGS. 1-3, the present invention provides a composite waterproof breathable tabi 10 that can extend in two directions, the composite waterproof breathable tabi 10 having a split toe portion 12 at the first end 14 and a first. The opening 16 of the two ends 18, the heel portion 20 in the middle between the first end 14 and the second end 18, the outer layer 22 having elastic twisted yarn inside, the inner layer 24, and the first end 14 A waterproof and breathable intermediate film 26 extending between the and the second end 18 and having a corrugated structure 28 in both the weft X direction and the warp Y direction, the corrugated structure 28 comprises a heel portion 20 and a second end. It has more extensibility between the heel portion 20 and the first end 14 than between 18 and 18.

More specifically, the present invention provides a composite waterproof breathable tabi 10 having a laminated structure, in which the inner layer 24 includes an inner layer body thread and the outer layer 22 includes an outer layer body thread. The inner layer body yarn is cotton, wool, acrylic, rayon, polyamide, polyester and / or any suitable material, or a mixture of materials, especially for the comfort of the wearer, and the intended use of the socks or It is selected according to the purpose. The outer layer main body yarn is polyamide, cotton, modal, polyester (particularly, a material selected according to the intended use or purpose of the tabi), and elastic twisted yarn having a twist number of 350 (T / m) is used. It is placed in the outer layer body thread.

By adopting this structure and composition, the composite waterproof and breathable tabi of the present invention has particularly longitudinal extensibility, giving the wearer a wide range of sizes of flexibility. The present invention eliminates the discomfort caused by conventional waterproof socks being too tight or too loose (large in size), and also tends to occur in composite socks manufactured by conventional techniques. Greatly reduces the possibility of wear on the toes. Having the elastic twisted yarn in the outer layer rather than the inner layer makes the inner layer looser and less stretchable, allowing the outer layer to better fit around the wearer's foot. It also provides comfort around the split toe portion 12.

The ratio of body yarn to additional spandex twisted yarn is 75:25.
The outer layer is knitted with a 13 gauge toe stock frame and has a heel portion.
The inner layer is knitted with a 13 gauge toe sock knitting machine. Also, the inner layer does not have a heel portion.
Alternatively, the inner layer is knitted with a 10 gauge toe sock knitting machine.

One or more adhesives 32 are used to join the outer layer 22, the inner layer 24, and the waterproof breathable intermediate film 26. A suitable adhesive 32 is a heat-activated thermoplastic polyurethane (TPU) material.

As shown in FIGS. 1 to 3, the waterproof and breathable intermediate film 26 has a corrugated structure in both the weft X direction and the warp Y direction, and is configured to have extensibility in the circumferential direction and the longitudinal direction.

The waterproof / breathable intermediate film 26 has a foot bag-like shape, and the adhesive is an inner surface of the waterproof / breathable intermediate film 26 in the state of separated dots or islands of the adhesive (inner layer of the waterproof / breathable intermediate film 26). It is located on both the side surface) and the outer surface (the surface on the outer layer side of the waterproof breathable intermediate film 26).

In the area of the tabi between the heel portion 20 and the first end 14, the adhesive separated dots or islands are from the adhesive separated dots or islands between the heel portion 20 and the second end 18 (FIG. 2). Are further separated from each other in both the weft X direction and the warp Y direction (FIG. 3).

The heel-like shape of the waterproof / breathable intermediate film 26 is larger than the relaxed inner and outer layers 24 and 22 of the composite structure before lamination, and therefore, when laminated to form the composite tabi structure, it is waterproof and breathable. The intermediate film 26 takes a corrugated form and has different spacing of adhesive dots or islands between each of the aforementioned regions, the corrugated structure 28 with the heel portion 20 rather than between the heel portion 20 and the second end 18. It has more extensibility between the first ends 14.

With this configuration, the waterproof and breathable intermediate film 26 sandwiched between the outer layer and the inner layer has a corrugated structure having different elongation characteristics in both the weft X direction and the warp Y direction in different regions of the tabi. It also allows the waterproof and breathable intermediate film 26 to stretch in the circumferential and longitudinal directions along the inner and outer layers and to different degrees when the tabi is worn. Further, the waterproof and breathable intermediate film 26 is more resistant to stretching in the region between the heel portion 20 and the first end 14 than in the region between the heel portion 20 and the second end 18.

This different stretch property gives the wearer of the tabi of the present invention improved comfort.
