Description

Technical field:

[0001] The invention relates to the field of masks, in particular to an antibacterial knitted mask with a replaceable filter element and a knitting method thereof. Background technology:

[0002] Traditional protective masks are made of a composite of non-woven fabric and filter material, and their appearance is relatively monotonous due to the influence of the material. Other types of protective masks with replaceable filter cartridges also need to be replaced after a certain number of uses. Gas mask-type masks with replaceable filter cartridges are not very convenient for daily carry and are expensive for the public to use. In summary, traditional mask products have their own advantages and certain shortcomings. In certain social environments (such as highly contagious epidemics), a reusable and protective mask is needed to meet widespread market demand. This can greatly meet demand and reduce the waste of other resources. Summary of the invention:

[0003] The technical problem to be solved by the present invention is to provide an antibacterial knitted mask with a replaceable filter element that has a prolonged service life, is breathable and comfortable to wear.

[0005] As a preferred option, the antibacterial layer and the breathable skin-friendly layer are woven together with antibacterial yarn, breaking through the limitations of traditional masks and opening up a new path for knitted masks.

[0006] Preferably, the antibacterial layer is woven from antibacterial wool yarn into a jacquard weave or a sandwich weave to form an antibacterial layer, thereby playing an antibacterial barrier role.

[0007] Preferably, the breathable skin-friendly layer is made of antibacterial cotton yarn knitted with alternate needles or with pick holes, which increases the breathability of the fabric.

[0008] Preferably, the antibacterial layer is woven from antibacterial wool yarn A, antibacterial wool yarn B, and antibacterial wool yarn C. The antibacterial wool yarn A and antibacterial wool yarn B are woven according to a pattern setting, and the antibacterial wool yarn C is introduced during the weaving process to form a non-woven interlayer. The non-woven interlayer makes the outer side less likely to deform.

[0009] As an example, the air layer tissue is a drum wave tissue, and the drum wave tissue is woven from antibacterial wool yarn C. The hollow part of the drum wave can be stuffed with plastic material to form a nose clip part.

[0010] Preferably, the filter element is a meltblown cloth, an activated carbon bag, or a carbonized cellulose bag.

[0011] The present invention also provides a method for knitting an antibacterial knitted mask with a replaceable filter element, using a flat knitting machine having a pair of front and rear needle beds extending in the left-right direction and facing each other in the front-to-back direction, comprising the following steps:

[0012] Step 1: Yarn D is knitted on one side in the right row to form the lower edge of the breathable skin-friendly layer;

[0013] Step 2: Start with the left row of yarn D and proceed to the left side to perform partial weaving of the hole stitch or alternate needle weaving to form a breathable inner interlayer that matches the outer antibacterial layer;

[0014] Step 3: Yarn D is woven into an air layer to form a connecting portion connecting the upper portion of the breathable skin-friendly layer and the upper portion of the antibacterial layer;

[0015] Step 4: Yarn A, yarn B, and yarn C start from the left row and end at the right row to the left side to partially weave jacquard weave or interlaced weave to form an outer interlayer part that matches the inner breathable skin-friendly layer;

[0016] Step 5: Yarn C starts from the left row and ends at the right row to the left side for single-sided weaving to form the lower edge of the antibacterial layer.

[0017] As a preference, the method comprises the following steps:

[0018] Step 1: Yarn D is knitted on one side in the right row to form the lower edge of the breathable skin-friendly layer;

[0019] Step 2: Start with yarn D on the left row, and weave a partial hole-picking structure to the left side to form an inner interlayer that matches the outer antibacterial layer.

[0020] Step 3: Yarn D is braided into a drum wave structure to form a connecting portion connecting the upper portion of the breathable skin-friendly layer and the upper portion of the antibacterial layer;

[0021] Step 4: Yarn A, yarn B, and yarn C start from the left row and end at the right row to the left side to perform partial weaving of jacquard interlaced yarn structure to form an outer interlayer part that matches the inner breathable and skin-friendly layer;

[0022] Step 5: Yarn C starts from the left row and ends at the right row to the left side for single-sided weaving to form the lower edge of the antibacterial layer.

[0023] Furthermore, yarn A, yarn B, and yarn C are antibacterial wool yarns, and yarn D is antibacterial cotton yarn.

[0024] Compared with the prior art, the present invention has the following advantages after adopting the above scheme: it can not only play a protective role, but also the main structure of the mask can be recycled by cleaning, greatly improving the service life of the product; the knitted coil composition characteristics also increase the air permeability of the fabric; its elasticity also makes the product easy to fold and carry, while increasing its wearing comfort; and the present invention breaks through the limitations of traditional masks and opens up a new path for knitted masks. It plays a certain role in better interpreting the design concept and improving the quality, artistic value and aesthetic value of the product, providing a broader development space for the development and market of knitted products; the present invention can weave knitted fabrics with richer texture and color contrast through the combination of knitted yarns with different properties (such as knitted yarns with different colors, shapes, elasticity, etc.), and its fabric products have a wide range of applications and huge market potential; in addition, in terms of industrial applicability, the knitting method of the present invention can be widely applied to all computerized flat knitting machines, which can meet and attract more consumer groups and promote the international influence of my country's knitting industry.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] Example 1

[0031] like Figure 1-4As shown, an antibacterial knitted mask with a replaceable filter element of the present invention comprises a mask body and ear straps. The mask body comprises an outer antibacterial layer 1 and an inner breathable skin-friendly layer 2. The upper portion of the antibacterial layer 1 and the upper portion of the breathable skin-friendly layer 2 are woven together through an air layer structure such as a drum wave structure 3. A shaping strip 4 is also inserted into the drum wave structure 3 to form a nose clip portion. The lower portion of the antibacterial layer 1 and the lower portion of the breathable skin-friendly layer 2 are joined and sutured together. The middle portion between the antibacterial layer 1 and the breathable skin-friendly layer 2 forms a sandwich, and the sandwich is filled with a filter element 5 through an opening on one side. Since the mask body of the present invention is woven from yarn, the ear straps can be woven together or sewn together using the ear straps of a conventional mask. The shaping strip is preferably a double-layer structure of an aluminum core and a plastic layer coated outside the aluminum core, and the aluminum core is preferably flat. In other words, the outer antibacterial layer and the upper part of the inner breathable skin-friendly layer are integrally formed through the drum wave structure, while the lower part is sewn together. As for the left and right sides, no sewing is required or only one side is sewn. Of course, the following improvement can also be made, and Velcro can be sewn on the inner surface of the opening side to close the opening side with the Velcro.

[0032] In this embodiment, the antibacterial yarn can be made of the same or different colors, making the antibacterial layer pattern more diverse. The antibacterial layer 1 and the breathable, skin-friendly layer 2 are integrally woven from the antibacterial yarn, breaking through the limitations of traditional masks and opening up a new path for knitted masks. Specifically, the antibacterial layer 1 is woven from antibacterial wool yarn into a jacquard weave 11 with a non-woven interlayer, providing an antibacterial barrier. The breathable, skin-friendly layer 2 is woven from antibacterial cotton yarn with a hole-punch pattern to enhance the fabric's breathability. Specifically, the antibacterial layer in this embodiment is woven from antibacterial wool yarn A, antibacterial wool yarn B, and antibacterial wool yarn C. Antibacterial wool yarns A and B are woven according to a set pattern, and antibacterial wool yarn C is introduced during the weaving process to form a non-woven interlayer. The non-woven interlayer prevents deformation of the outer surface. The air layer is composed of a wavy weave 3 woven from antibacterial wool yarn C. The hollow portion of the wavy weave 3 can be filled with plastic material to form the nose clip. Among them, the drum wave structure and the hole-picking structure both belong to the organizational structure of the knitting industry and belong to the scope of the existing technology. The specific contents of the drum wave structure and the hole-picking structure will not be described in detail. Similarly, non-woven interlayer yarn is also a well-known technology in the knitting industry. The antibacterial wool yarn C is fixed by introducing and utilizing the coils formed by the intersection of the above two yarns during the weaving process of the antibacterial wool yarn A and the antibacterial wool yarn B.

[0033] In this application, the filter element part is not the innovation of the present invention. The filter element of the mask on the market can be directly configured, such as the filter element is meltblown cloth or activated carbon bag. Of course, it can also be configured with a more environmentally friendly carbonized cellulose bag. The activated carbon bag and the carbonized cellulose bag are made by placing activated carbon particles or carbonized cellulose particles in a sealed bag made of non-woven fabric.

[0034] The antibacterial knitted mask with replaceable filter element of the present invention adopts a method of knitting or pleating the mask body from bottom to top with different yarn mouths and different tissues on a computer flat knitting machine to form the mask shape. Figure 1 As shown, taking partial weaving as an example, the shaded part is the non-woven part, where part ① is the antibacterial layer 1 on the outside of the mask. Yarn A, yarn B and yarn C are used to weave the jacquard weave and incorporate the interlaced yarn weave. Yarn A and yarn B can be woven according to the design requirements; and yarn C is interlaced yarn, so that the antibacterial layer on the front side is not easily deformed. Part ② is the drum wave weave 3 on the upper edge of the mask body. Yarn C is used to weave the drum wave weave. The hollow part of the drum wave weave 3 can be stuffed with plastic material such as a shaping strip 4 to form a nose clip part, as shown in FIG. Figure 2 ③ is the breathable skin-friendly layer 2 on the inside of the mask, which is made of yarn D with a perforated weave 21 or a spacer weave to make the fabric more dry and breathable. ④ and ⑤ are the lower edges of the inner and outer sides of the mask body, respectively. They need to be connected and sutured to form the lower edge of the mask. After suture, the middle layer is stuffed with a replaceable filter element (such as Figure 2 ), play a protective role.

[0035] The knitting method of the antibacterial knitted mask with a replaceable filter element of the present invention uses a flat knitting machine having a pair of front and rear needle beds extending in the left-right direction and facing each other in the front-back direction, comprising the following steps:

[0036] Step 1: Yarn D is knitted on one side in the right row to form the lower edge of the breathable skin-friendly layer;

[0037] Step 2: Start with yarn D on the left row, and weave a partial hole-picking structure to the left side to form an inner interlayer that matches the outer antibacterial layer.

[0038] Step 3: Yarn D is braided into a drum wave structure to form a connecting portion connecting the upper portion of the breathable skin-friendly layer and the upper portion of the antibacterial layer;

[0039] Step 4: Yarn A, yarn B, and yarn C start from the left row and end at the right row to the left side to perform partial weaving of jacquard interlaced yarn structure to form an outer interlayer part that matches the inner breathable and skin-friendly layer;

[0040] Step 5: Yarn C starts from the left row and ends at the right row to the left side for single-sided weaving to form the lower edge of the antibacterial layer.

[0041] Among them, yarn A, yarn B, and yarn C are antibacterial wool yarns, and yarn D is antibacterial cotton yarn.

[0042] The above description is only for the preferred embodiment of the present invention, which should not be understood as limiting the claims. Any equivalent structure or equivalent process transformation made by using the description of the present invention is included in the patent protection scope of the present invention.
