The utility model relates to a seamless swimsuit which is formed by seamlessly weaving sandwich fabric, the sandwich fabric is composed of a
skin-attaching layer, an outer
surface layer and a middle layer connecting the
skin-attaching layer and the outer
surface layer, the
skin-attaching layer adopts special-shaped terylene as basic
yarn and adopts coarse denier spandex as additional
yarn to be woven into plain stitch plaiting texture, the middle layer adopts fine denier spandex, and the outer
surface layer is made of
polyester fiber. And the outer surface layer is woven into a plain stitch by
polypropylene fibers. According to the utility model, the skin-attaching layer adopts the plain plaiting weave formed by weaving the special-shaped
polyester and the coarse denier spandex, and is hydrophobic, quick to dry, skin-friendly and comfortable; the outer surface layer is of a water-repellent tissue structure woven by
polypropylene fibers, and the middle layer adopts fine denier spandex to connect the outer layer and the inner layer, so that the elasticity is increased, tissue pores of the outer layer and the inner layer are filled, the capillarity is reduced, and the water-repellent capacity is enhanced. In addition, according to different requirements of all parts of the
human body, coarse denier spandex is configured, and plaiting weaving is carried out in good time to achieve the body shaping effect.
