Abstract
Description
Technical Field
[0001] The utility model relates to the field of fabrics, and more particularly to a breathable polyester-spandex rib fabric. Background Art
[0002] Rib knits are a basic weave pattern for weft-knitted fabrics, consisting of a fixed arrangement of wales of front and back stitches. Rib knits exhibit significant elasticity and extensibility when stretched horizontally. They are often used in sportswear and casual wear. The elasticity of rib fabrics enhances comfort and fit, while also adding a more fashionable and sporty touch.
[0003] The fabric is formed by ribbing polyester and spandex, which makes the fabric elastic and wear-resistant. However, due to the poor air permeability of polyester fiber and spandex fiber, the fabric has poor breathability.
[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a breathable polyester-spandex rib fabric.
[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: a breathable polyester-spandex rib fabric includes a base layer, which is woven by four needle tracks, wherein the fourth longitudinal row of coils is a reverse coil, and the base layer forms a bulge at the longitudinal row of the reverse coils. The pattern of the base layer is a four-way cycle, wherein a single-needle single-row tuck is formed on the second needle of the third track, and an air hole is formed at the single-needle single-row tuck. A convex strip is formed on the side of the base layer facing away from the bulge, and the convex strip is located on both sides of the air hole. The length direction of the convex strip is perpendicular to the length direction of the bulge.
[0007] The utility model is further configured as follows: the second and fourth paths of the base layer are padded with reinforcing yarns, the reinforcing yarns are located in front of the first and third needles, and the reinforcing yarns are located in the back of the second and fourth needles.
[0008] The utility model is further configured as follows: the reinforcing yarn comprises a yarn core and an outer covering yarn wound around the yarn core, the yarn core is an elastic yarn, and the outer covering yarn is a low-elastic yarn.
[0009] The utility model is further configured as follows: the elastic yarn is formed by twisting a plurality of spandex fibers.
[0010] The utility model is further configured as follows: the low-elastic yarn is formed by twisting a plurality of polyester fibers.
[0011] The present utility model is further configured such that: the first, second, third, and fourth yarns of the base layer are each formed by twisting a plurality of polyester fibers.
[0012] In summary, the present utility model has the following beneficial effects:
[0013] By forming ventilation holes on the base layer, the air permeability of the base layer is improved. The ventilation holes are formed by single-needle single-row tuck formed on the second needle of the third row. Since the fourth longitudinal row of coils is a reverse coil, a protrusion is formed on the fourth longitudinal row, and a rib is formed on the other side of the base layer. The rib is located on both sides of the ventilation hole, so that the protrusion and the rib can support the ventilation hole. At the same time, the length directions of the protrusion and the rib are perpendicular to each other, so that the support effect on the ventilation hole is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0019] The breathable polyester-ammonia rib fabric, as Figures 1 to 3 shown, includes a base layer. The base layer is knitted by a four-needle track, wherein the fourth longitudinal row of coils is a reverse coil. A protrusion 5 is formed on the base layer at the longitudinal row of the reverse coil. The pattern of the base layer is a four-row cycle, and a single-needle single-row tuck is formed on the second needle of the third row. A ventilation hole 1 is formed on the base layer at the single-needle single-row tuck. A rib 6 is formed on the side of the base layer facing away from the protrusion 5. The rib 6 is located on both sides of the ventilation hole 1. The length direction of the rib 6 is perpendicular to the length direction of the protrusion 5. By forming the ventilation hole 1 on the base layer, the air permeability of the base layer is improved. The ventilation hole 1 is formed by a single-needle single-row tuck formed on the second needle of the third row. Since the fourth longitudinal row of coils is a reverse coil, a protrusion 5 is formed on the fourth longitudinal row, and a rib 6 is formed on the other side of the base layer. The rib 6 is formed by knitting polyester fibers on the base layer by an embroidery machine. The rib 6 is located on both sides of the ventilation hole 1, so that the protrusion 5 and the rib 6 can support the ventilation hole 1. At the same time, the length directions of the protrusion 5 and the rib 6 are perpendicular to each other, so that the support effect on the ventilation hole 1 is better.
[0020] Such as Figure 2 andFigure 3 As shown, reinforcing yarn 2 is padded on the second and fourth paths of the base layer. The reinforcing yarn 2 is located on the second and fourth paths, increasing the tear resistance at the ventilation holes 1. When the reinforcing yarn 2 is padded, it passes through single-needle single-row tucking. The yarn density at the tucking area of the reinforcing yarn 2 is thicker, which can form convex points. The convex points can also support the ventilation holes 1. The reinforcing yarn 2 is located on the front side of the first and third needles and on the rear side of the second and fourth needles, thus increasing the friction between the reinforcing yarn 2 and the base layer and further improving the tear resistance of the base layer. The reinforcing yarn 2 includes a yarn core and an outer wrapping yarn wound around the yarn core. The yarn core is an elastic yarn 3, and the outer wrapping yarn is a low-elastic yarn 4. By setting the yarn core as the elastic yarn 3, the reinforcing yarn 2 has elasticity. The outer wrapping yarn uses the low-elastic yarn 4, so that after the reinforcing yarn 2 is stretched, the low-elastic yarn 4 can be tightened to achieve a tear-resistant effect. The elastic yarn 3 is twisted by several spandex fibers. The spandex fibers have good elasticity, thus enabling the elastic yarn 3 to have elastic deformation characteristics. The low-elastic yarn 4 is twisted by several polyester fibers. The polyester fibers have good hardness, so that the low-elastic yarn 4 has good hardness. When the elastic yarn is tightened, it achieves a tear-resistant effect. The yarns of the first, second, third, and fourth paths are all twisted by several polyester fibers, thus increasing the strength of the base layer.
[0021] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
