Abstract
Description
Technical Field
[0001] This utility model relates to fabric technology, and more specifically, to antibacterial knitted fabric. Background Technology
[0002] Knitted fabric is a material woven by a knitting machine. Due to its good elasticity and other characteristics, knitted fabric is often used as a raw material for making windproof face masks and the like.
[0003] Because the windproof mask is in close contact with people's mouth and nose, the air people exhale creates a warm and humid environment on the windproof mask. At the same time, the shedding of the stratum corneum on people's faces provides nutrients for the survival of bacteria, which makes it very easy for a large number of bacteria to grow on the raw fabric used to make the windproof mask.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide antibacterial knitted fabric.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: antibacterial knitted fabric, including a base layer and an antibacterial layer, wherein the base layer and the antibacterial layer are connected by hot melt adhesive, wherein pleats protruding away from the antibacterial layer are formed on the base layer, an air cavity is formed between the pleats and the antibacterial layer, wherein a plurality of air-permeable gaps are formed on the base layer, and a plurality of air-permeable holes are formed on the antibacterial layer, wherein the area of the air-permeable gaps is larger than the area of the air-permeable holes.
[0007] The present invention is further configured such that: the base layer is formed by weaving base yarn to form a tucked structure, the base layer is woven with five needles and its pattern is four rows and one cycle, wherein a three-needle single-row tucked structure is formed on the second row, and the breathable gap is located at the three-needle single-row tucked structure.
[0008] The present invention is further configured such that: the antibacterial layer is formed by woven comb GB1 yarn, comb GB2 yarn and comb GB3 yarn together, the air vents are formed by symmetrical padding of comb GB1 yarn and comb GB2 yarn, and the comb GB3 yarn is woven into a chain structure.
[0009] The present invention is further configured such that: the padding yarn number of the GB1 comb yarn is 1-0 / 1-2 / 2-3 / 2-1 / / one thread and one empty, and the padding yarn number of the GB2 comb yarn is 2-3 / 2-1 / 1-0 / 1-2 / / one thread and one empty.
[0010] The present invention is further configured such that the padding number of the GB3 comb yarn is 0-1 / / one thread and one empty.
[0011] The present invention is further configured such that the combed GB3 yarn includes a core yarn and an antibacterial yarn wound around the outside of the core yarn, wherein the core yarn is made of several low-elastic polyester yarns twisted together.
[0012] The present invention is further configured such that the antibacterial yarn is made of several bamboo fibers twisted together.
[0013] In summary, this utility model has the following beneficial effects: When people use the windproof face mask made of this fabric, the antibacterial layer disrupts the survival environment of bacteria on the fabric, making it difficult for bacteria to grow on the fabric, thereby improving the antibacterial performance of the fabric. The two-layer superposition method can effectively increase the thickness of the fabric while also ensuring its warmth. At the same time, the air cavity can effectively slow down the heat exchange rate between the external air and the inside of the fabric, thereby further ensuring the warmth of the fabric. The design of the ventilation gap and ventilation holes can effectively ensure the breathability of the fabric. The area of the ventilation gap is set to be larger than the area of the ventilation hole, so that a large amount of cold air from the outside will not suddenly enter people's mouth and nose through the ventilation hole, thereby effectively avoiding discomfort caused by suddenly inhaling a large amount of cold air.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Antibacterial knitted fabric, such as Figure 1As shown, the fabric includes a base layer 1 and an antibacterial layer 2, which are connected by hot melt adhesive. The base layer 1 has raised folds 3 facing away from the antibacterial layer 2, and an air cavity 4 is formed between the folds 3 and the antibacterial layer 2. Several breathable gaps 5 are formed on the base layer 1, and several breathable holes are formed on the antibacterial layer 2. The area of the breathable gaps 5 is larger than the area of the breathable holes. This two-layer superposition method effectively increases the thickness of the fabric while also ensuring its warmth. Simultaneously, the air cavity 4 effectively slows down the heat exchange rate between the two sides of the fabric, further ensuring its warmth. The breathable gaps 5 and the breathable holes effectively ensure the fabric's breathability. Setting the area of the breathable gaps 5 larger than the area of the breathable holes prevents a large amount of cold air from passing through the fabric all at once. The antibacterial layer 2 prevents bacteria from easily growing on the windproof face mask made from this fabric, thus effectively improving the fabric's antibacterial properties.
[0023] like Figures 2 to 4 As shown, base layer 1 is woven with base yarn to form a tucked structure. Base layer 1 is woven with five needles, and its pattern is a four-way repeat. The second way forms a three-needle single-row tucked structure. The ventilation gap 5 is located at the three-needle single-row tucked structure. Specifically, the needle arc of the second needle of the second way of yarn crosses the third needle loop of the first way and is then placed on the sinker arc of the fourth needle loop of the first way. The needle arcs of the second to fourth needle loops of the third way of yarn are all moved upward and placed on the second needle of the first way of yarn respectively. On the sinking arc of the fourth needle loop, the air gap 5 formed by the empty needles from the second to the fourth needle of the second row can better ensure air passage, thus ensuring the air permeability of the base layer 1. The antibacterial layer 2 is woven together using comb GB1 yarn, comb GB2 yarn, and comb GB3 yarn. The air holes are formed by symmetrical padding of comb GB1 yarn and comb GB2 yarn. The comb GB3 yarn is woven into a chain structure. The padding number of the comb GB1 yarn is 1- 0 / 1-2 / 2-3 / 2-1 / / One thread, one gap; the padding number of the GB2 guide yarn is 2-3 / 2-1 / 1-0 / 1-2 / / One thread, one gap; the padding number of the GB3 guide yarn is 0-1 / / One thread, one gap. Specifically, the warp-knitted mesh structure formed by the symmetrical padding of the GB1 and GB2 guide yarns creates air holes on the antibacterial yarn 7. Both the GB1 and GB2 guide yarns are woven into a warp-knitted structure. At this time, the antibacterial... The air vent formed by one empty needle on layer 2 has a smaller area than the air vent formed by three empty needles on layer 1. This prevents air passing through the air vent 5 from passing through the air vent simultaneously. The braided structure formed by the combed GB3 yarn can improve the tensile strength of antibacterial layer 2 in the warp direction, while also reducing the number of empty needles on antibacterial layer 2. This reduces the number of air vents on antibacterial layer 2 and also reduces the amount of external air entering after passing through the air vents.
[0024] like Figure 5 and Figure 6 As shown, the GB3 comb yarn includes a core yarn 6 and an antibacterial yarn 7 wrapped around the core yarn 6. The core yarn 6 is made of several low-elastic polyester yarns twisted together, and the antibacterial yarn 7 is made of several bamboo fibers twisted together. The low-elastic polyester yarns have good tensile strength to ensure the core yarn 6, thereby ensuring the tensile strength of the antibacterial layer 2 in the warp direction. The antibacterial yarn 7 is made of several bamboo fibers twisted together. Bamboo fibers have natural antibacterial properties. The antibacterial yarn 7 made of bamboo fibers twisted together can effectively ensure the antibacterial performance of the antibacterial layer 2, thereby effectively ensuring the antibacterial performance of this fabric.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model.
