Description

Technical Field

[0001] This invention application belongs to the technical field of fully-fashioned knitting, and particularly relates to a knitted fully-fashioned facial protection product and its preparation method. Background Art

[0002] With the continuous improvement of global health protection needs and the rapid development of protection product technologies, the design of face masks and respirators not only needs to meet basic protection performance, but also must provide higher comfort and functionality for the actual use scenarios of wearers. Compared with traditional respirators, face masks can provide a larger coverage area while also offering additional visual clarity and protection advantages for wearers. However, traditional respirators and face masks often neglect the balance between comfort and functionality in their design. Especially when wearing glasses, insufficient sealing in the nose and facial areas causes exhaled moisture to easily rise to the lens area, leading to fogging, which seriously affects visual clarity. This problem is more obvious in special scenarios such as medical work, outdoor sports, and industrial operations, not only increasing the inconvenience of use, but also potentially affecting safety and work efficiency.

[0003] Compared with respirators, although face masks have more advantages in overall sealing, they still face problems such as insufficient breathability, moisture accumulation, and stuffiness in high-temperature and high-humidity environments. Especially when worn for a long time, this discomfort will be amplified, seriously affecting the use experience. In addition, since face masks usually cover a larger area, how to further improve comfort, reduce moisture and heat accumulation while ensuring protection performance, and at the same time take into account lightweight design has become a key challenge in the design. Summary of the Invention

[0031] (1) In this invention application, based on the flat knitting one-piece forming technology and the double-layer fiber structure design, the facial protection product innovatively integrates the zero-wet-cold feeling of the inner layer and the local safety prompt reflective characteristic of the outer layer. Through the differential capillary effect and the wetting gradient effect, the unidirectional conduction of moisture from the inner layer to the outer layer is realized, effectively preventing the moisture from flowing back, and always keeping the inner layer of the facial protection product dry and comfortable; at the same time, the three-dimensional solid forming and the flat knitting double-sided structure of the facial protection product can realize the precise knitting of multiple fibers and multiple tissues through the knitted fully-formed technology, without cutting and sewing, greatly reducing material waste and subsequent processes, and efficiently integrating the cool feeling, moisture conduction, and reflective characteristics into one.

[0032] (2) In this invention application, first of all, the inner layer of the facial protection product uses cool-sensing fiber polyethylene, which quickly dissipates heat through its special heat conduction performance when contacting the skin, providing a cool and comfortable wearing experience; the outer layer of the facial protection product can be composed of ultra-fine polyester fibers, and the capillary structure thereof forms a difference in fineness and hygroscopicity with the inner layer fibers, jointly promoting the unidirectional discharge of moisture, avoiding the accumulation of moisture inside the face shield, and relieving the stuffiness and wet stickiness during long-term wearing; in addition, through the three-dimensional solid forming technology, a convex structure or a raised structure with high fittingness is designed on both sides of the nose wings, which closely fits the human facial contour, effectively blocking the upward diffusion of moisture, significantly reducing the phenomenon of glasses fogging, optimizing the moisture guidance and air permeability of the large-area protection area of the face shield, and improving the overall sealing and moisture dissipation performance of the face shield; in addition, in the nose and mouth area, an air-permeable pore structure design is adopted, and the air flow circulation is enhanced through the purl process, reducing the breathing resistance, ensuring the comfort and practicability during long-term wearing, and embedding reflective yarn in the outer layer, which not only meets the daily protection needs, but also significantly improves the safety in night and low-light environments, and is especially suitable for scenarios such as outdoor operations, traffic command, and night activities.

In order to make the purpose, technical solutions and advantages of the present invention application clearer, the embodiments of the present invention application will be further described in detail below in conjunction with the accompanying drawings.

[0047] In the first aspect, as Figures 1 to 10 shown, a preparation method for a knitted fully formed facial protection product includes:

[0048] Step S100: Prepare a knitted fully formed mask;

[0049] Specifically, step S100 includes: performing production weaving on a first four-bed fully formed computerized flat knitting machine, using a first yarn feeder, a second yarn feeder, and a third yarn feeder. The first yarn feeder feeds polyester fibers, the second yarn feeder feeds polyethylene fibers, and the third yarn feeder feeds reflective yarn; weaving a first hanging rope part G11, a first reflective part B11, a mask face D1, a mask ventilation part C1, a second reflective part B12, a nose wing convex part A1, and a second hanging rope part G12 to form a knitted fully formed mask.

[0050] In some embodiments, the first four-needle bed can be the Shima Seiki MACH2XS153-15G four-needle bed; polyethylene fiber: as the inner layer material of the mask, it can quickly dissipate heat when contacting the facial skin, reduce the body surface temperature, and reduce the discomfort of wearing; superfine polyester fiber: as the outer layer material, its hygroscopicity is slightly stronger than that of the inner layer material, and it promotes the conduction of moisture from the inner layer to the outer layer through differential capillary action; reflective yarn: embedded in the upper and lower edges on the outside to improve visibility in night or low-light environments, and is suitable for night running or outdoor work scenarios.

[0051] In some embodiments, the first yarn feeder can feed 6 pieces of 75D / 288F polyester fiber, the second yarn feeder can feed 6 pieces of 75D / 24F cool-sense fiber (polyethylene), and the third yarn feeder can feed 1 piece of 0.16 mm reflective yarn. Of course, those skilled in the art can also adjust the above settings according to the actual situation, and this application of the present invention does not make special restrictions on this.

[0052] Specifically, step S100 includes:

[0053] Step S101: Weaving the first hanging rope part G11 and the second hanging rope part G12 both include: using a 2-way one-cycle plating knitting process through the first yarn feeder and the second yarn feeder to form a 2+2 false rib structure.

[0054] In this application of the present invention, the first hanging rope part G11 and the second hanging rope part G12 adopt a false rib design, so that the first hanging rope part G11 and the second hanging rope part G12 have excellent elasticity and can quickly return to their original shape after stretching, which can prevent indentation or discomfort, ensure the comfort and stability of the user during long-term wearing, and will not slack or deform. The appropriate edges and thickness of the first hanging rope part G11 and the second hanging rope part G12 can effectively avoid excessive pressure on the ears.

[0055] Step S102: Weaving the first reflective part B11 and the second reflective part B12 both include: realizing through a 6-way one-cycle knitting process through the first yarn feeder and the third yarn feeder; the 1st and 2nd ways use polyester fiber for knitting on the back needle bed, and the 3rd, 4th, 5th, and 6th ways use reflective yarn for knitting on the front needle bed to form the first reflective part B11 and the second reflective part B12 on the upper and lower sides of the outside of the mask.

[0056] In the application of the present invention, first, the reflective areas of the first reflective part B11 and the second reflective part B12 are distributed in the form of strips at the upper and lower edges of the outside of the mask, ensuring the independence and stability of the reflective functional area. A high-brightness reflective yarn embedding structure is adopted. These reflective yarns can significantly reflect light sources under low-light or night conditions, improving the reflective effect and night recognition ability, and providing additional safety protection for the wearer. In addition, the reflective yarns are integrally woven through the fully-fashioned technology, which not only enhances the durability of the reflective effect but also avoids the discomfort or reduced durability problems that may be caused by additional stitching. The softness of the materials of the first reflective part B11 and the second reflective part B12 is consistent with that of the main fabric of the mask, ensuring that good reflective performance and a neat appearance can still be maintained after washing.

[0057] Step S103: Weaving the mask face D1 includes: realizing through the first yarn nozzle and the second yarn nozzle using an 8-way one-cycle knitting process. When knitting the mask in the 1st, 3rd, 5th, and 7th ways, the back needle bed uses polyethylene fiber full-needle knitting to form a cool-sensation area inside the mask; the 2nd, 4th, 6th, and 8th ways use polyester fiber knitting on the front needle bed to form a support area outside the mask; during the knitting process of the 2nd and 6th ways, some knitting needles on the front needle bed simultaneously form loops on the back needle bed, so that the inner layer of the mask is connected to the outer layer of the mask, and at least a certain distance is reserved between the inner layer and the outer layer of the mask.

[0058] In the application of the present invention, the difference in fiber fineness and hygroscopicity between the inner layer and the outer layer of the mask constructs a one-way moisture conduction function. The core area is located in the inner layer material in contact with the skin and at least a certain distance is reserved between the inner layer and the outer layer of the mask. The inner layer uses cool-sensation fiber polyethylene, and its thick capillary tubes quickly capture moisture, while the ultra-fine polyester on the outer layer transports the moisture to the outside through finer capillary tubes, forming an obvious wetting gradient effect, ensuring that moisture is quickly absorbed from the wearer's breath or sweat and exported outward. The process of moisture export strictly avoids the phenomenon of reverse osmosis, effectively promoting the one-way moisture conduction effect of moisture, ensuring the structural stability and breathability of the mask, and keeping the inner layer of the mask always dry and comfortable. Especially in hot or high-humidity environments, it significantly reduces the damp feeling inside the mask, avoids the discomfort caused by sticking to the skin, and improves the wearing comfort and functionality.

[0059] Step S104: Weaving the mask ventilation part C1 includes: through the first yarn nozzle and the second yarn nozzle, using an 8-way one-cycle knitting process. The 1st, 3rd, 5th, and 7th ways use polyester fiber full-needle knitting on the front needle bed to form a support structure outside the mask; the 2nd, 4th, 6th, and 8th ways use polyethylene fiber on the back needle bed when knitting the mask to form the mouth and nose breathing area of the mask. When knitting the 2nd and 6th ways, some knitting needles on the back needle bed turn over to the front needle bed, so that the mouth and nose breathing area of the mask forms a breathable pore structure.

[0060] In the application of the present invention, first, the breathable pore structure is located directly in front of the mouth and nose. Through the purl knitting process, a uniform breathable pore structure can be formed. The purl process endows the breathable pore structure with elasticity, enabling it to conform to the facial curve as the wearing position is adjusted, and the air permeability effect will not be affected by deformation. Additionally, the tissue fabric of the breathable pore structure adopts a three-dimensional structure design, which can enhance the air circulation efficiency, reduce moisture accumulation, improve air permeability, reduce breathing resistance, and enhance the wearing comfort. The setting of the breathable pore structure is suitable for long-term wearers, such as outdoor athletes or workers who need to wear masks all day long, helping them relieve the stuffy feeling and keep breathing smoothly.

[0061] Step S105: Weaving the nose wing convex part A1 includes: Through the first yarn guide, using a 4-way knitting cycle design, full-needle knitting process is carried out in the 2nd and 4th ways, that is, all knitting needles participate in the operation to form a uniform and tight coil structure; in the 1st and 3rd ways, partial-needle knitting process is adopted, that is, some knitting needles are hung up and do not participate in knitting, and some knitting needles carry out tissue knitting to form a relatively sparse coil structure; the full-needle knitting process and the partial-needle knitting process are carried out alternately, so that there is a difference in the coil density between the upper and lower adjacent ways, resulting in unbalanced tension, guiding the knitted mask to wrinkle in a local area to form the convex structure on both sides of the nose wings.

[0062] In the application of the present invention, to solve the technical problem of anti-fogging of glasses, a convex structure, namely the nose wing convex part A1, is designed on both sides of the mask corresponding to the nose wings. The position of the nose wing convex part A1 is in the area from below the bridge of the nose to both sides of the nose wings. Through precise three-dimensional forming technology design, it highly conforms to the contour of the human nose, adopts a flexible arc transition to avoid the oppressive feeling that may be caused by sharp structures, and forms a stable convex shape by increasing the local fabric thickness and density. The convex structures on both sides of the nose wings close the gap between the nose and the mask, reduce the path of exhaled moisture escaping upward, and reduce the probability of moisture entering the glasses area. The design of the nose wing convex part A1 is combined with the seamless one-piece forming process, without the need for sewing fixation, which not only maintains the comfort during wearing but also avoids the problem of weak airtightness that may occur in traditional sewing.

[0063] In the application of the present invention, first of all, the nasal wing convex part A1 can be formed by a specific knitting method (such as interlaced knitting, longitudinal knitting or transverse knitting, knitting, etc.). The nasal wing convex part A1 has certain elasticity and flexibility. When the wearer wears the mask, these wrinkled or convex parts can be appropriately deformed according to the facial contour to provide a better fitting feeling and comfort. In addition, the nasal wing convex part A1 can also be designed to have a pocket structure. By filling shape memory alloy, memory foam or smart polymer material inside, the nasal wing convex part A1 is allowed to make self-adaptive adjustment when the external environment changes or the facial shape changes. For example, when the wearer speaks or smiles, the shape memory material in the pocket structure will undergo a slight deformation, so that the nasal wing convex part A1 can be adjusted accordingly, which can effectively reduce the facial pressure and avoid discomfort after long-term wearing, thereby improving the fitting and comfort of the mask.

[0064] Optionally, in step S100, the overall knitting direction of the knitted seamless mask is: starting from the chin and knitting towards the bridge of the nose.

[0065] In some embodiments, such as Figure 2 and Figure 6 As shown, the first hanging rope part G11 includes the first ear part ① and the first rope part ③, and the second hanging rope part includes the second ear part ② and the second rope part ④. When knitting, starting from the first ear part ① of the first hanging rope part G11, then the number of tissues gradually increases and will hang down naturally. When knitting to the junction with the second rope part ④ of the second hanging rope part G12, stop knitting, hang the knitted tissues on the knitting needles, and then sequentially knit the first rope part ③ of the first hanging rope part G12, the first reflective part B11, a part of the mask face D1, the mask ventilation part C1, a part of the mask face D1, the second reflective part B12, the second rope part ④ and the second ear part ② of the second hanging rope part G12, and finally knit the nasal wing convex part A1.

[0066] In some embodiments, such as Figure 6 As shown, since the mask presents an arc-shaped structure and the length of each row is different, it is necessary to perform needle increasing and decreasing when knitting the main body part, so that the knitted tissues gradually extend or shorten. During the weaving process, the front needle bed can knit the external tissues of the mask, and the rear needle bed can knit the internal tissues of the mask. At the same time, the front needle bed continuously makes loops to the rear needle bed to keep the tissues of the front needle bed and the tissues of the rear needle bed connected, that is, the first hanging rope part G11, the first reflective part B11, the mask face D1, the mask ventilation part C1, the second reflective part B12, the nasal wing convex part A1, and the second hanging rope part G12 are connected.

[0067] And / or, step S200: Prepare a knitted seamless face mask;

[0068] Specifically, step S200 includes: producing and weaving on a second four-bed full-fashioned computerized flat knitting machine, using nozzle 1, nozzle 2, and nozzle 3. Nozzle 1 feeds in navy blue polyester fibers, nozzle 2 feeds in polyester fibers, and nozzle 3 feeds in reflective yarn; weaving the third lanyard part G21, the mask mandible part E, the third reflective part B21, the mask face part D2, the mask ventilation part C2, the fourth reflective part B22, the nasal wing bulge part A2, the mask forehead part F, and the fourth lanyard part G22 to form a knitted full-fashioned mask.

[0069] In some embodiments, the second four-bed can be a Shima Seiki MACH2XS153-15G four-bed, and the first four-bed full-fashioned computerized flat knitting machine and the second four-bed full-fashioned computerized flat knitting machine can be the same; Navy blue polyester fibers: As the outer layer material of the mask, dark polyester fibers have excellent light absorption and light shielding properties. They can not only absorb and lock heat, thus effectively resisting the invasion of cold air currents, but also improve the UV protection ability of the mask, playing a certain sun protection effect, which is suitable for winter cycling scenarios; Polyester fibers: As the outer layer material, the hygroscopicity is slightly stronger than that of the inner layer material, and the differential capillary effect promotes the conduction of moisture from the inner layer to the outer layer; Reflective yarn: Embedded in the upper and lower edges on the outside to enhance visibility in night or low-light environments, which is suitable for night running or outdoor work scenarios. There can be a difference in the number of fiber roots between the inner and outer layers. The outer layer tissue is denser, having certain windproof characteristics and one-way moisture conduction characteristics, which can promote the export of internal moisture and keep the face dry and comfortable.

[0070] In some embodiments, nozzle 1 can feed in 6 pieces of 84D / 384F polyester fibers (navy blue), nozzle 2 feeds in 6 pieces of 75D / 288F polyester fibers, and nozzle 3 feeds in 1 piece of 0.16mm reflective yarn. Of course, those skilled in the art can also adjust the above settings according to the actual situation, and this application of the present invention does not make special restrictions on this.

[0071] Specifically, step S200 includes:

[0072] Step S201: Weaving the third lanyard part G21 and the fourth lanyard part G22 both include: Through nozzle 1 and nozzle 2, using a two-way one-cycle plating knitting process to form a 2+2 mock rib structure.

[0073] In the application of the present invention, the third lanyard part G21 and the fourth lanyard part G22 adopt a mock rib design, making the third lanyard part G21 and the fourth lanyard part G22 have excellent elasticity. After being stretched, they can quickly return to their original shape, preventing indentation or discomfort, ensuring the comfort and stability of the user during long-term wearing, without sagging or deforming. The appropriate edges and thickness of the third lanyard part G21 and the fourth lanyard part G22 can effectively avoid excessive pressure on the ears.

[0074] Step S202: The weaving of the third reflective part B21 and the fourth reflective part B22 both includes: realized by using a 6 - path one - cycle knitting process through the 1st yarn feeder and the 3rd yarn feeder; the 1st and 2nd paths use polyester fibers for knitting on the back needle bed, and the 3rd, 4th, 5th, and 6th paths use reflective yarns for knitting on the front needle bed to form the third reflective part B21 and the fourth reflective part B22 on the upper and lower sides of the outer part of the mask.

[0075] In this invention application, first of all, the reflective areas of the third reflective part B21 and the fourth reflective part B22 are distributed in a strip - like form in the eye - ring area of the mask, ensuring the independence and stability of the reflective functional area. A high - brightness reflective yarn embedding structure is adopted. These reflective yarns can significantly reflect light sources under low - light or night conditions, enhancing the reflective effect and night recognition ability, providing additional safety protection for the wearer; in addition, the reflective yarns are integrally knitted through the full - shaping technology, which not only enhances the durability of the reflective effect but also can avoid the discomfort or durability reduction problems caused by additional stitching. The softness of the materials of the third reflective part B21 and the fourth reflective part B22 is consistent with that of the main fabric of the mask, which can ensure that good reflective performance and neat appearance can still be maintained after washing.

[0076] Step S203: The weaving of the mask face D2 includes: realized by using an 8 - path one - cycle knitting process through the 1st yarn feeder and the 2nd yarn feeder. When knitting the mask, the 1st, 3rd, 5th, and 7th paths use polyethylene fibers for full - needle knitting on the back needle bed to form a cool - feeling area inside the mask; the 2nd, 4th, 6th, and 8th paths use polyester fibers for knitting on the front needle bed to form a support area outside the mask; during the knitting of the 2nd and 6th paths, some knitting needles on the front needle bed simultaneously make loops on the back needle bed, so that the inner layer of the mask is connected to the outer layer of the mask, and at least part of the inner layer and the outer layer of the mask retain a certain distance.

[0077] In this invention application, the difference in fiber fineness and hygroscopicity between the inner layer and the outer layer of the mask constructs a one - way moisture - guiding function. The core area is located in the inner - layer material in contact with the skin and at least part of the inner layer and the outer layer of the mask retains a certain distance. The inner layer uses cool - feeling fiber polyethylene, whose thick capillary tubes quickly capture moisture, while the ultra - fine polyester on the outer layer transports the moisture to the outside through finer capillary tubes, forming an obvious wetting gradient effect, ensuring that moisture is quickly absorbed from the wearer's breath or sweat and exported outwards. The process of moisture export strictly avoids the phenomenon of reverse osmosis, effectively promoting the one - way moisture - guiding effect of moisture, ensuring the structural stability and breathability of the mask, making the inner layer of the mask always remain dry and comfortable, especially in hot or high - humidity environments, significantly reducing the damp feeling inside the mask, avoiding the discomfort caused by sticking to the skin, and improving the wearing comfort and functionality.

[0078] Step S204: The breathable part C2 of the mask is woven as follows: Through nozzle 1 and nozzle 2, using an 8 - course cyclic knitting process, in the 1st, 3rd, 5th, and 7th courses, full - needle knitting with polyester fiber is used on the front needle bed to form the support structure of the outer part of the mask; in the 2nd, 4th, 6th, and 8th courses when knitting the mask, polyethylene fiber is used on the back needle bed to form the oral - nasal breathing area of the mask. When knitting in the 2nd and 6th courses, some knitting needles on the back needle bed turn over to the front needle bed, so that the oral - nasal breathing area of the mask forms a breathable pore structure.

[0079] In the present invention application, first of all, the breathable pore structure is located directly in front of the mouth and nose. Through the purl knitting process, a uniform breathable pore structure can be formed. The purl process makes the breathable pore structure elastic, which can fit the facial curve with the adjustment of the wearing position and will not affect the breathable effect due to deformation. In addition, the tissue fabric of the breathable pore structure adopts a three - dimensional structure design, which can enhance the air circulation efficiency, reduce the accumulation of moisture, improve the breathability, reduce the breathing resistance, and enhance the wearing comfort. The setting of the breathable pore structure is suitable for long - time wearers, such as outdoor athletes or workers who need to wear masks all day long, helping them reduce the stuffy feeling and keep breathing smoothly.

[0080] Step S205: The nose - wing raised part A2 is woven as follows: Through nozzle 1, using a 4 - course knitting cycle design, in the 2nd and 4th courses, full - needle knitting process is carried out, that is, all knitting needles participate in the operation to form a uniform and tight coil structure; in the 1st and 3rd courses, partial - needle knitting process is adopted, that is, some knitting needles are suspended without participating in knitting, and some knitting needles carry out tissue knitting to form a sparser coil structure; the full - needle knitting process and the partial - needle knitting process are carried out alternately, so that there is a difference in the coil density between the adjacent upper and lower courses, resulting in an unbalanced tension, which guides the locally wrinkling of the knitted mask to form the raised structure on both sides of the nose wings.

[0081] In the present invention application, the nose - wing raised part A2 is the same as the nose - wing raised part A1 in step S105. Correspondingly, the technical problems, technical solutions, and technical effects of the nose - wing raised part A2 and the nose - wing raised part A1 in step S105 can be exactly the same. Specifically, all the contents in step S105 can be referred to, and the present invention application will not elaborate on this again.

[0082] Step S206: The mask lower - jaw part E is woven as follows: Through nozzle 1 and nozzle 2, using a 3 - course cyclic plating process to form a 1 + 3 false rib structure.

[0083] In the present invention application, a 1+3 false rib structure can be formed by adjusting the needle number interval of loop formation and float line. The 1+3 false rib structure can effectively reduce friction, provide a more uniform pressure distribution, enable the lower jaw part of the mask to have sufficient tightening force, achieve the tightening and bulging effects of the mask, so that the mask can better fit the skin, enhance the comfort and support force of mask wearing, avoid sliding or gaps during use, enhance the sealing performance of the mask, effectively prevent the intrusion of external air, dust or bacteria, and at the same time ensure that the mask remains stable and unchanged during various sports or daily activities, play its due protection function, and improve the wearing flexibility and comfort.

[0084] Step S207: Weaving the forehead part F of the mask includes: using a 15-course alternate knitting process through the first yarn feeder and the second yarn feeder to form a knitted three-dimensional concave-convex structure. The loops of the 4th-9th courses and the 10th-15th courses are continuously unformed, resulting in the natural tightening of the mask after weaving to form a concave structure.

[0085] In the present invention application, the forehead part is usually the area where sweating is most concentrated. Especially in a sports or high-temperature environment, the sweat on the forehead is easy to accumulate, resulting in discomfort. In order to improve the comfort and functionality of the forehead area, a special three-dimensional concave-convex structure design can be adopted. The three-dimensional concave-convex structure can increase the surface area of the fabric, making it have stronger moisture absorption ability, and at the same time can accelerate the discharge and evaporation of sweat; the design of the three-dimensional concave-convex structure not only helps with moisture absorption and sweat discharge, but also can reduce the situation of sweat retention by improving air circulation, so as to keep the forehead dry and avoid sweat flowing into the eyes or other facial areas causing discomfort.

[0086] Optionally, in step S200, the overall knitting direction of the knitted fully-fashioned mask is: starting from the chin and knitting towards the bridge of the nose.

[0087] In some embodiments, in some embodiments, such as Figure 8 and Figure 9 shown, the third hanging cord part G21 includes the third ear part ⑤ and the third cord part ⑦, and the fourth hanging cord part includes the fourth ear part ⑥ and the fourth cord part ⑧. During knitting, starting from the third ear part ⑤ of the third hanging cord part G21, the number of tissues gradually increases and will naturally hang down. When knitting reaches the junction with the fourth cord part ⑧ of the fourth hanging cord part G22, stop knitting, hang the knitted tissues on the knitting needles, and then sequentially knit the third cord part ⑦ of the third hanging cord part G21, the lower jaw part E of the mask, the facial part D2 of the mask, the breathable part C2 of the mask, the third reflective part B21, the nasal wing bulge part A2, the fourth reflective part B22, the forehead part F of the mask, the fourth cord part ⑧ of the fourth hanging cord part G22, and the second ear part ⑥.

[0088] During the knitting process of the face mask, due to the existence of an eye-opening area in the design, in order to ensure the integrity and knitting accuracy of the overall structure, wedge knitting needs to be adopted. By dynamically controlling the knitting needles, "knitting while pausing" is achieved. That is, for the non-knitting area at the eye-opening of the mask, by selectively pausing the operation of the corresponding needle bed, these knitting needles are temporarily stopped, thus avoiding the formation of unnecessary yarn connections or tissue distortion. For the needles that continue to participate in knitting, they knit the tissue structure according to the preset knitting path to ensure the knitting continuity of other areas of the mask. Through wedge knitting, the eye-opening area of the mask can be directly formed during the knitting process without subsequent cutting or splicing, greatly improving the production efficiency and also ensuring the overall structural strength and aesthetics of the mask.

[0089] In some embodiments, the method for preparing a knitted fully-fashioned facial protection product may separately include preparing a knitted fully-fashioned mask or separately include preparing a knitted fully-fashioned face mask. When the first four-bed fully-fashioned computerized flat knitting machine and the second four-bed fully-fashioned computerized flat knitting machine are the same and are essentially one computerized flat knitting machine, when there is one or more of the first four-bed fully-fashioned computerized flat knitting machines and one or more of the second four-bed fully-fashioned computerized flat knitting machines, or when the structure and / or function of the first fully-fashioned computerized flat knitting machine and the structure and / or function of the second fully-fashioned computerized flat knitting machine are integrated into one computerized flat knitting machine, the knitted fully-fashioned mask and the knitted fully-fashioned face mask can be prepared successively by one computerized flat knitting machine or multiple computerized flat knitting machines for control weaving; or when the first four-bed fully-fashioned computerized flat knitting machine and the second four-bed fully-fashioned computerized flat knitting machine are combined and the method for preparing a knitted fully-fashioned facial protection product is used for weaving, the knitted fully-fashioned mask and the knitted fully-fashioned face mask can be prepared simultaneously, or one computerized flat knitting machine can use the method for preparing a knitted fully-fashioned facial protection product to prepare the knitted fully-fashioned mask and the knitted fully-fashioned face mask simultaneously to meet the needs of industrial mass production.

[0090] In the method for preparing a knitted fully-fashioned facial protection product of the present invention application, the facial protection product is designed based on the horizontal knitting integrated forming technology and the double-layer fiber structure, and innovatively integrates the characteristics of zero wet cold feeling on the inner layer and local safety prompt reflectivity on the outer layer. Through the differential capillary effect and the wetting gradient effect, the unidirectional conduction of moisture from the inner layer to the outer layer is realized, effectively preventing the backflow of moisture and always keeping the inner layer of the facial protection product dry and comfortable; the three-dimensional forming and horizontal knitting double-sided structure of the facial protection product can achieve precise knitting of multiple fibers and multiple tissues through the knitted fully-fashioned technology, without cutting and sewing, greatly reducing material waste and subsequent processes, and efficiently integrating the characteristics of cool feeling, moisture conduction, and reflectivity.
