Description

Technical Field

[0001] This utility model relates to the textile field, and more specifically, to a breathable knitted fabric. Background Technology

[0002] Knitted fabric is a type of fabric formed by interlocking loops. It is characterized by good elasticity, breathability, softness, and comfort, and is widely used in clothing, home textiles, and industrial textiles. Knitted fabric is generally divided into two main types: warp knitting and weft knitting. Both warp and weft knitting have various production and processing methods, which bring different properties to the knitted fabric. Breathability is a common requirement for knitted fabric. To improve breathability, knitted fabric will form breathable mesh by offsetting the loops. However, large areas of breathable holes will reduce the light-blocking properties of the knitted fabric. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a breathable knitted fabric.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable knitted fabric, including a base layer, wherein the base layer includes a base yarn and a reinforcing yarn, wherein the reinforcing yarn is in groups of two, and the base yarn is looped only between the two reinforcing yarns in the same group.

[0005] The present invention is further configured such that the reinforcing yarn has a continuous braided structure.

[0006] The present invention is further configured such that: the base yarn includes a first yarn and a second yarn, wherein the first yarn and the second yarn form overlapping warp loops between the reinforcing yarns in the same group.

[0007] The present invention is further configured such that: the padding number of the first yarn is 0-2 / 5-3 / / one thread and two empty threads, and the padding number of the second yarn is 5-3 / 0-2 / / one thread and two empty threads.

[0008] The present invention is further configured such that the padding yarn of the reinforcing yarn is numbered 2-1 / / one thread and one empty.

[0009] The present invention is further configured such that the reinforcing yarn is made of twisted nylon fiber bundles.

[0010] In summary, this utility model has the following beneficial effects: Although the yarn structure between the two sets of reinforcing yarns is relatively loose, there are still yarns that cross and cover, ensuring the light-blocking properties of the knitted fabric. This allows the knitted fabric to have both breathability and light-blocking properties. The nylon fiber bundles have good tensile strength, and combined with the high stability of the chain braiding structure, they ensure the dimensional stability of the knitted fabric and prevent large dimensional changes in the breathable parts. The overlapping of the first and second yarns through the warp loops enhances the structural stability of the base layer. The cross-lacing of the first and second yarns between the two sets of reinforcing yarns further ensures the light-blocking properties of the knitted fabric. Attached Figure Description

[0011] Figure 1 This is a diagram showing the movement of the first yarn in this invention.

[0012] Figure 2 This is a diagram showing the movement of the second yarn in this invention.

[0013] Figure 3 This is a diagram showing the movement of the reinforcing yarn padding in this utility model. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example: A breathable knitted fabric, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a base layer, which consists of a base yarn and a reinforcing yarn. The reinforcing yarn is in pairs, and the base yarn is looped only between the two reinforcing yarns in the same group. The reinforcing yarn has a continuous chain structure, and the padding yarn of the reinforcing yarn is numbered 2-1 / / one thread and one gap. The reinforcing yarn is made of twisted nylon fiber bundles.

[0016] Specifically, the base layer is formed by weaving base yarn and reinforcing yarn together on a warp knitting machine. The reinforcing yarn forms a continuous closed-loop chain structure. Between two reinforcing yarns in the same group, adjacent base yarns form loops and connect with each other. Between two adjacent groups of reinforcing yarns, there are only cross lines formed by the back-shifting of the base yarn needles, without interconnected loops. Therefore, the loose structure improves the breathability of the knitted fabric. At the same time, although the yarn structure between the two groups of reinforcing yarns is relatively loose, there are still yarns that cross and cover, ensuring the light-blocking properties of the knitted fabric. This gives the knitted fabric both breathability and light-blocking properties. The nylon fiber bundles have good tensile strength, and combined with the high stability of the chain structure, the dimensional stability of the knitted fabric is ensured, avoiding large dimensional changes in the breathable parts.

[0017] like Figure 1 , Figure 2 , Figure 3As shown, the base yarn includes a first yarn and a second yarn. The first yarn and the second yarn form overlapping warp loops between the reinforcing yarns in the same group. The padding yarn number of the first yarn is 0-2 / 5-3 / / one thread through two gaps, and the padding yarn number of the second yarn is 5-3 / 0-2 / / one thread through two gaps.

[0018] Specifically, both the first and second yarns are made of twisted polyester fiber bundles. The polyester fiber bundles are hydrophobic, which reduces the impact of yarn moisture absorption on breathability. The first and second yarns overlap with each other through recurved loops, which enhances the structural stability of the base layer. The cross-threads of the first and second yarns between the two sets of reinforcing yarns further ensure the light-blocking properties of the knitted fabric.

[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
