Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of textile fabric, specifically, relates to an antibacterial moisture absorption and ventilation knitted fabric. BACKGROUND

[0002] Fabric is the material used to make clothes. As one of the three elements of clothes, fabric not only can interpret the style and characteristics of clothes, but also directly affects the performance effect of color and modeling of clothes. In the world of clothes, there are various fabrics for clothes, which change rapidly. However, in general, high-quality and high-grade fabrics have several characteristics, such as comfortable to wear, sweat-absorbing and breathable, drape and upright, visual noble, and tactile soft.

[0003] In summer, for people who are easy to sweat, if the fabric is not breathable and has poor moisture absorption and quick drying performance, the fabric is easy to adhere to the skin, resulting in poor wearing comfort. In addition, the general fabric has poor antibacterial effect, which leads to the breeding of bacteria inside when wearing, thereby affecting the health of the body.

[0004] The prior art with publication number CN214266841U discloses an antibacterial and breathable moisture-conducting fabric, which comprises a moisture-conducting layer, an antibacterial layer, a spandex core yarn layer, a banana fiber layer and an inner layer. The moisture-conducting layer is bonded with a waterproof and breathable layer on the top. The bottom of the moisture-conducting layer is connected with the top of the antibacterial layer. The bottom of the antibacterial layer is connected with the spandex core yarn layer. The bottom of the spandex core yarn layer is connected with the top of the banana fiber layer. A plurality of air holes are arranged between the antibacterial layer and the spandex core yarn layer. The air holes penetrate through the antibacterial layer and the spandex core yarn layer from top to bottom. The bottom of the banana fiber layer is connected with the inner layer. The prior art has the following problems: the fabric has many layers, the fabric is thick, and the fabric has poor breathability, antibacterial property and quick drying performance. SUMMARY

[0005] Therefore, the utility model aims at providing an antibacterial moisture absorption and ventilation knitted fabric to solve the problems of the prior art, such as many layers of fabric, thick fabric, poor breathability, poor antibacterial property and poor quick drying performance of the fabric.

[0006] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0007] An antibacterial moisture absorption and ventilation knitted fabric is knitted by two upper needle discs and two lower needle cylinders, and is knitted in 12 ways for one cycle, wherein the arrangement order of the structure of the knitted fabric is as follows:

[0026] Further, the loop length of the first route, the second route, the fourth route, the sixth route, the seventh route, the eighth route, the tenth route and the twelfth route is 13-15cm / 50 needles.

[0027] The arrangement not only ensures the tightness of the fabric, but also makes the fabric have better air permeability and quick-drying property.

[0028] Further, the loop length of the third route, the fifth route, the ninth route and the eleventh route is 6-8cm / 50 needles.

[0029] The arrangement not only ensures the tightness of the fabric, but also makes the fabric have better air permeability and quick-drying property.

[0030] Further, the grammage of the knitted fabric is 135-140g / m2.
