Description

Technical Field

[0001] The invention relates to a modular design method of an ergonomic flat-knitted protective top based on functional zoning, and belongs to the technical field of protective clothing design. Background Art

[0002] As the safety risks faced at work and in life are increasing, people are paying more and more attention to the safety protection of their bodies. The demand for flexible protective clothing has also become more diverse and complex, that is, it is no longer limited to a single physical protection function, but can provide diversified and professional protective clothing solutions according to the specific needs of different industries and different types of work. As functional clothing, protective clothing needs to integrate multiple functions to ensure the safety and comfort of the wearer. These functions do not exist in isolation, nor can they be simply combined. Even in different parts of the body, functional conflicts will occur. Therefore, careful coordination and balance are required in different areas of the human body.

[0003] At present, research on flexible protective clothing mainly focuses on the preparation of fabrics, focusing on improving their protective properties.

[0004] Patent CN 220734469 U discloses a new type of protective clothing with protective functions, including a protective top and protective pants, the protective top and protective pants both include an outer layer and an inner layer; the outer layer and the inner layer are made of breathable, skin-friendly and protective materials, which are used as the basic fabrics of the protective top and protective pants; a protective layer is provided between the outer layer and the inner layer; the protective layer includes a flexible protective layer and a passivation protective layer; the flexible protective layer and the passivation protective layer are fixedly connected; the flexible protective layer is in contact with the inner layer; the passivation protective layer is in contact with the outer layer. In this patent, the addition of the protective layer effectively improves the protective effect of the protective clothing. However, the four-layer structure increases the thickness of the clothing, and the comfort and sensitivity of wearing are not high enough.

[0005] Patent CN 214156277 U discloses a new type of cut-resistant clothing, which is composed of a multi-layer structure, including a surface layer, a cut-resistant layer, a buffer layer and an inner layer. The surface layer is specially provided with breathable micropores to ensure air circulation. The cut-resistant layer uses precision-woven UHMWPE to provide excellent cut protection. The buffer layer uses elastic metal wire material to enhance the impact absorption capacity. The inner layer uses cotton fiber to improve wearing comfort. The layers are tightly combined by precision sewing technology. The design of the breathable area on the chest and back takes into account human motion engineering, but it is obviously only a simple regional design, and the production process of its garment process is cumbersome, the process flow is complex, and the time and labor costs are high. The design concept of reasonable zoning protection for different parts of the human body has not been realized.

[0006] Horizontal knitting has diverse structures and flexible shapes, and can meet multiple functions. In recent years, it has gradually been used in sports and leisure clothing, shoe uppers, and professional sports accessories. However, when weaving protective clothing, due to the lack of reasonable functional zoning, there will be the following problems during horizontal knitting, such as insufficient protection performance in key parts: protective clothing with unreasonable zoning has insufficient protection performance in key parts such as the heart and abdomen, and cannot provide the corresponding level of protection, thereby reducing the overall protection effect; the characteristics of horizontal knitting have not been brought into play: unreasonable zoning design has caused the protective clothing to fail to fully utilize the characteristics of horizontal knitting, such as elasticity, breathability, comfort, etc., affecting the functionality and wearing experience of the protective clothing; ignoring ergonomic characteristics: protective clothing with unreasonable zoning ignores ergonomic characteristics when worn, which may cause discomfort, restricted activities, or affect work efficiency. In view of the problems of poor comfort, single protective function, and lack of reasonable functional zoning in existing protective clothing. Further refined design of protective clothing based on horizontal knitting. Summary of the invention

[0007] In order to solve the problems existing in the prior art, the present invention is based on the diverse characteristics of horizontal knitted structures, takes protection function as the main body, integrates ergonomic theory, and proposes a modular design method of ergonomic horizontal knitted protective tops based on functional zoning.

[0008] The present invention is achieved through the following technical solutions: The first object of the present invention is to provide a modular design method for an ergonomic flat-knitted protective top based on functional zoning, comprising the following steps: S1. Obtain customer demand for protective clothing, and analyze the demand to generate demand data; S2. Functional zoning of protective tops is carried out according to the functional zoning principle; the functional zoning principle includes the outer protective functional zoning principle, the inner protective functional zoning principle and the special functional zoning principle; among them, the outer protective functional zoning is divided into chest>upper abdomen>waist and hips>shoulder, back≥head>upper limbs according to the level; the inner protective functional zoning is divided into abdomen≥waist>back>head>upper arm≥forearm=chest according to the level; special functional zoning includes high breathability area and high flexibility area; S3. Combine the demand data of step S1 and process the functional partitions of step S2 according to the functional partition processing logic, including setting the priority of the outer protection functional partition and the inner protection functional partition, adjusting the number of functional partitions, and selecting special functional partitions; S4. According to the horizontal knitting tissue matching logic, the functional partitions processed in step S3 are matched with the corresponding horizontal knitting tissue structures from the horizontal knitting tissue library to obtain the functional partition model of the protective top; the horizontal knitting tissue matching logic is to first clarify the outer layer anti-cutting and inner layer warmth retention levels required for each partition, then evaluate the anti-cutting and warmth retention capabilities of each tissue in the tissue library, and then select tissues that meet or exceed the minimum requirements of each partition, and sort them in descending order according to the priority of outer layer protection and inner layer protection, and finally ensure that the key areas are optimally protected and prioritize matching of high-priority tissues; S5. Verify the functional zoning model of the protective jacket obtained in step S4.

[0009] In one embodiment of the present invention, the requirements in step S1 include one or more of functional requirements, application environment requirements, style requirements, partition quantity requirements, thermal and humidity requirements, or flexibility requirements.

[0010] In one embodiment of the present invention, in step S3, the logic for setting the priority of the outer layer protection function zone and the inner layer protection function zone is as follows: the outer layer protection priority is higher than the inner layer protection for the parts facing the direct threat of cutting, the inner layer protection priority is higher than the outer layer protection for the parts that are not easily cut but susceptible to cold, and for the parts that cannot be distinguished between the threat of cutting and the feeling of cold, the priority is set according to the outer layer protection level being higher than the inner layer protection level.

[0011] In one embodiment of the present invention, in step S3, the principle for adjusting the number of functional partitions is: first retain the partitions of the highest and lowest levels, and adjust the middle partitions according to the principle of balanced quantity and merging of similar levels.

[0012] In one embodiment of the present invention, the horizontal knitting tissue library is constructed by the following method: designing horizontal knitting tissues of different levels suitable for different application scenarios, establishing a tissue process module, and storing and managing the performance characteristics, key parameters, applicable area range and example image information of the tissue process module in the form of a database.

[0013] In one embodiment of the present invention, it also includes regular maintenance and updating of the horizontal knitting tissue library.

[0014] In one embodiment of the present invention, different functional zones in the functional zone model of the protective top are connected by two methods: hot pressing and adding / overlapping needles. In the present invention, complex and diverse tissue structures are the key to ensuring the diverse zones of protective clothing and excellent protective functions. For complex tissue structures, a large number of four-level and double rib structures will be used, and one-piece molding machines cannot weave them. The present invention uses hot pressing and adding / overlapping needles to connect different functional zones. The prepared garment has no seams and is very soft.

[0015] In one embodiment of the present invention, the flat knitted structure is prepared by a double-needle-bed computerized flat knitting machine or a four-needle-bed computerized flat knitting machine.

[0016] In one embodiment of the present invention, the outer protective structure of the flat knitted structure is woven by high-performance yarn, preferably ultra-high molecular weight polyethylene yarn. The high-performance yarn in the present invention is a yarn with high strength, high modulus, impact resistance, low density, cutting resistance, wear resistance, bending resistance and the like.

[0017] In one embodiment of the present invention, the inner protective structure of the flat knitted structure is woven with warm yarn, preferably polyester fancy crochet yarn.

[0018] The second object of the present invention is to provide a modular design system for ergonomic flat-knitted protective tops based on functional zoning, which is used to implement the modular design method for ergonomic flat-knitted protective tops based on functional zoning, comprising: Demand analysis module, used to obtain customer demand for protective clothing, and analyze the demand to generate demand data; Functional zoning module, functional zoning of protective tops according to functional zoning principles; the functional zoning principles include outer layer protection functional zoning principles, inner layer protection functional zoning principles and special functional zoning principles; among them, the outer layer protection functional zoning is divided into chest>upper abdomen>waist and hips>shoulder, back≥head>upper limbs according to levels; the inner layer protection functional zoning is divided into abdomen≥waist>back>head>upper arm≥forearm=chest according to levels; special functional zoning includes high breathability area and high flexibility area; The partition processing module processes the functional partitions of the functional partition module according to the functional partition processing logic in combination with the demand data generated by the demand analysis module, including setting the priority of the outer protection functional partition and the inner protection functional partition, adjusting the number of functional partitions, and selecting special functional partitions; The horizontal knitted tissue matching module matches the functional partitions processed by the partition processing module with the corresponding horizontal knitted tissue structure from the horizontal knitted tissue library according to the horizontal knitted tissue matching logic, and obtains the functional partition model of the protective top; the horizontal knitted tissue matching logic is to first clarify the outer layer anti-cutting and inner layer warmth retention levels required for each partition, and then evaluate the anti-cutting and warmth retention capabilities of each tissue in the tissue library, and then select tissues that meet or exceed the minimum requirements of each partition, and sort them in descending order of priority of outer layer protection and inner layer protection, and finally ensure that key areas are optimally protected, and give priority to matching high-priority tissues.

[0019] Previously, technicians in this field had little research on the zoning of protective clothing, and the focus was on improving the protective function. The present invention further refines the design of protective clothing from the perspective of clothing design. The combination of functional zoning from multiple angles of the present invention is not simply pieced together, but a combination of various types of functional zoning principles, making the functional zoning more accurate and reasonable, and avoiding the contradictions and conflicts of simple patchwork.

[0020] In addition, the present invention adopts a multi-layer structure design of a flat knitted structure, so that the structure is more coordinated and comprehensive in function. The matching logic is more in line with actual needs, and the matching accuracy and effectiveness are improved.

[0021] The present invention organically combines functional zoning, protective clothing, and horizontal knitting under the theory of ergonomics, and provides a more scientific reference for the combination relationship between the organizational structure of protective clothing and clothing design.

[0022] Beneficial effects of the present invention: (1) The modular design method of the ergonomic horizontal knitted protective top based on functional zoning described in the present invention is based on a horizontal knitted structure, with tightly connected fabrics and good overall stability. The protective clothing made of the fabrics has good softness and integrity while maintaining high protective performance.

[0023] (2) The modular design method of the ergonomic flat-knitted protective top based on functional zoning described in the present invention has a simple process flow and convenient application. It focuses on optimizing the functional zoning of the protective top to provide more accurate and effective protection, so that the protective clothing conforms to the physiological characteristics of the human body and takes into account the flexibility of movement.

[0024] (3) The modular design method of the ergonomic flat-knitted protective top based on functional zoning described in the present invention can provide an advanced protective clothing system that can effectively meet various protection needs while ensuring the comfort and adaptability of the wearer.

[0035] Embodiment 1: This embodiment provides a modular design method for an ergonomic flat-knitted protective top based on functional zoning.

[0036] Figure 1 A flowchart of a modular design methodology based on functional zoning of an exemplary embodiment of the present invention is shown, and the process of the methodology includes the following key steps. S1: Demand analysis of horizontal knitted protective clothing; S2: Functional zoning principles; S3: Functional zoning logic; S4: Functional zoning template; S5: Modular design verification and application. In step S1 of this embodiment, it is clarified that the protective clothing is applicable to public safety and industrial fields, aiming to provide very effective cut-resistant protection while maintaining the flexibility and comfort of the wearer. In step S2, based on the principle of ergonomics, the outer layer protection function zoning principle 11, the inner layer protection function zoning principle 12 and the special function zoning principle 13 are formulated to divide the clothing into multiple modules with different protection levels. In step S3, the functional zoning processing logic 14 and the horizontal knitting organization matching logic 15 are formulated by comprehensively considering the yarn characteristics, horizontal knitting organization structure and wearing requirements. In step S4, based on the functional zoning logic, a functional zoning model is generated, and it is integrated with the horizontal knitting organization library through the organization matching logic to form a functional zoning template for horizontal knitted protective clothing.

[0037] S2: Functional zoning principle.

[0038] in, Figure 2The figure shows the division basis of the functional partition modules of an exemplary embodiment of the present invention. The division of the functional partition modules is crucial and is strictly set according to the differences in clothing pattern, human body size, and internal and external protective parts of the human body. Referring to GB / T 38131-2019 "Method for obtaining human body measurement reference points for clothing" and GB / T 16160-2017 "Dimensional definition and method for human body measurement for clothing", the upper body reference points and related dimension measurement reference lines required by an exemplary embodiment of the present invention are selected. The reference points include the head vertex TP, the submental point GN, the side neck point SNP, the shoulder end point SP, the shoulder and neck continuous midpoint NP, the axilla point AP, the elbow point EP and the wrist point WP. The dimension measurement reference lines include the front chest width FBW, the chest circumference B, the lower chest circumference UB, the waist circumference W, the hip circumference H, the back width BBW, the back length NWL, the shoulder line SL, the hip height HH, the sleeve width SW, the upper arm length UAL and the forearm length FL. According to the above parameters and the body contour line, the size and position of the functional partition module are determined to ensure that the module is evenly divided and meets the basic rules of clothing technology.

[0039] Figure 3The outer protective function zoning diagram of an exemplary embodiment of the present invention is shown. In view of the characteristics of the human anatomical structure, the internal organs are mainly concentrated in the core area of ​​the trunk, the chest and abdomen, while the limbs and head are supported by bones. Most stab injuries in the chest and abdomen of the front trunk will cause fatal threats, so this area is the most important. Further subdivided, the chest has life-sustaining organs such as the heart and lungs, and their degree of protection is more important than the abdominal organs that are mainly responsible for digestion and metabolism. The back trunk and head have the spine and skull to protect the internal organs and the brain, and the degree of protection is relatively low. Among them, the waist of the back trunk has a slightly higher degree of protection than the back. The upper limbs are supported by bones and have the lowest degree of protection. Therefore, the outer protective function zoning system is subdivided into six areas, chest module 31>upper abdomen module 32>waist and hip module 33>shoulder, back module 34≥head module 35>upper limb module 36. The protection levels are arranged in descending order from E1, E2, E3, E4, E5, and E6. The chest module 31 is determined by the lower bust UB, chest circumference B, and 1 / 3 front chest width FBW to determine the circumference size, and the position is determined by the armpit point AP. The upper abdomen module 32 is determined by the waist circumference W, and the height is half of the hip height HH, which is the upper abdomen area. The front area of ​​the waist and hip module 33 is established by the hip circumference H, which is the lower abdomen area; the circumference of the back waist area is determined by the waist circumference W and hip circumference H, and the height size is determined by the hip height HH. As shown in the figure, the shoulder and back module 34 uses the back width BBW and waist circumference W as the module circumference size, and the position is determined by AP, SP, and SNP. The head module 35 uses the head vertex TP and the submental point GN as the height size and point position, and determines the module area in combination with the head contour. The upper limb module 36 is determined by the shoulder point SP and the wrist point WP as the point position, the circumference size is determined by the sleeve width SW, and the length size is determined by the arm length UAL+FL.

[0040] Figure 4The figure shows the inner layer protection function partition diagram of an exemplary embodiment of the present invention. The inner layer protection (warmth) level is divided according to the difference in cold sensitivity of various parts of the human body in a low temperature environment. The human body trunk is more sensitive to cold than the limbs. Among them, the abdomen is the most sensitive to cold, followed by the back (including the waist). The head, as an important part of heat loss, is also more sensitive to cold, and the shoulders are less likely to feel cold than the back. What is more special is that the chest area itself generates more heat, so it feels comfortable in a low temperature environment and has the weakest cold sensitivity, while the forearm has better blood circulation and is relatively less sensitive to cold than the upper arm. Based on this, the importance level of the inner layer protection function of the human body can be divided into modules, abdomen module 41 ≥ waist module 42> back module 43> head module 44> upper arm module 45 ≥ forearm module 46 = chest module 46. The inner layer protection (warmth) level system is divided into I1, I2, I3, I4, I5, I6, and the protection level decreases in sequence. The abdominal module 41 is determined by the reference line from the lower bust UB to the hip circumference H, and the circumference size is proposed to be 1 / 3 of the lower bust UB and 1 / 3 of the hip circumference H, with a trapezoid representing the upper and lower abdominal triangles. The waist module 42 is divided into the front waist and the back waist, which are evenly distributed on both sides of the lower half of the trunk except the abdominal area. The back waist position is lowered, with the waist circumference W and the hip circumference H as the boundary, and the circumference size is 1 / 4W. The back module 43 is the entire area after removing the waist module 42. The module size and position division of the head module 44 are consistent with the outer layer protection function zoning. The upper arm module 45 and the forearm module 46 are divided into two parts based on the upper limb module 36 at the elbow point EP, with the module 45 above the EP point and the module 46 below the EP point. The chest module 46 is in the area above the lower bust UB of the front body.

[0041] Figure 5 A special functional zoning diagram of an exemplary embodiment of the present invention is shown. When the human body is moving, the clothing needs to have a certain amount of looseness at the elbows and shoulder joints of the arms, and a high flexibility demand area can be set. The sweating degree of the human body trunk is much higher than that of the human body limbs, especially the armpits, shoulders, back and middle chest of the human body, and a high breathability demand area can be set. Therefore, a high breathability demand area can be set, and the division of heat and humidity areas takes into account the arc of the body parts. The above requirements are relatively special, and usually do not need to be divided as detailed as the protection level. Special areas such as Figure 5As shown, it includes special functional zones 51 and 52, and the levels are recorded as T1 and T2. The high breathability zone module 51 is mainly distributed in the front chest, back and armpit. The front chest module is between the lower chest circumference UB and the front chest width FBW, located in the middle of the chest, and the module circumference dimensions are 1 / 3FBW and 1 / 3UB respectively. The back module is between the shoulder endpoint connection line SPL and the waistline W on both sides, located in the middle of the back, and the circumference dimensions are 1 / 4APL and 1 / 3W respectively. The underarm module is an area with chest circumference and APL as size boundaries. The high flexibility zone module 52 is mainly distributed in the elbow and shoulder. The elbow module is centered on the elbow point EP, with the sleeve width SW as the circumference basis, extending to the upper arm and forearm, and the length dimension is 1 / 6 (UAL+FL). The shoulder module is divided into areas based on the reference points NP, SP and the reference line SW, and the front and back sides are symmetrical and consistent. The division of the special functional zones is only a suggestion for the selection of functional zones. Even after the modular functional zone template is generated, it can still be flexibly adjusted according to specific needs.

[0042] S3: Functional partitioning logic.

[0043] Among them, when integrating the functional zoning model, it is necessary to consider the needs of different protective functional zones and the balance between them, which involves the material properties, organizational structure, and actual wearing needs of users in the horizontal knitting tissue library. Therefore, a zoning logic is formulated, including a functional zoning processing logic 14 and a horizontal knitting tissue matching logic 15. The functional zoning processing logic 14 is as follows. For zones with high levels of outer protective functions, a high proportion of UHMWPE yarn is usually required. However, the high proportion of UHMWPE yarn also brings the side effect of strong thermal conductivity, which affects the warmth retention of the fabric, which is the main conflict. If different functional zones conflict in the same part, the first thing to do is to set priority rules. In general, the outer protective function should take precedence over the inner protective function, because the outer protective function is related to the safety protection of the clothing, while the inner protective function focuses on comfort. Life safety is more important than comfort. But the priority can also be adjusted in different parts. For areas facing direct cutting threats, such as the chest and abdomen, the outer layer protection (anti-cutting) has a higher priority. For areas that are relatively less susceptible to cutting but susceptible to cold, such as the waist and hips, back, and head, the inner layer protection (cold and warmth) has a higher priority. The arms do not have high requirements for both anti-cutting and cold and warmth, which can be balanced according to practical conditions, or one of the functional requirements can be retained. The final functional zoning template also needs to be dynamically adjusted according to the actual wearing needs of consumers, which can be mainly summarized as the requirements for the number of functional zones and the selection of special functional requirements. From the functional zoning principle S2 step, it can be obtained that, combined with the outer layer protection functional zone 11 and the inner layer protection functional zone 12 (11), and the special functional zone 13 (2), there are a total of 13 different functional zone modules. First of all, for the requirements for the number of functional zones, if such a fine division is not required, only a rough division is required, and the zones need to be merged. The principle is to first retain the highest and lowest level zones, and the middle zones are adjusted according to the principle of balanced quantity and merging of similar levels. Therefore, the module 31 (level E1) and the module 32 (level E2) can be combined into a high outer protection partition module, and the numbering follows the higher level partition. Then the middle outer protection partition modules include 33 and 34 (levels E3 and E4); the low outer protection partition modules are 35 and 36 (levels E5 and E6). The obtained functional partition template is not unique, but more diverse. Secondly, the selection of special functional requirements mainly includes a high flexibility module 51 and a high breathability module 52. The arm has a low level of outer protection function 11 and inner protection function 12, so the corresponding high flexibility requirement area can be added according to the demand, and adjusted according to the number of partitions of the former. The chest and back both have high requirements for protection functions. Under the premise of not affecting the basic protection function, a certain breathable area in a small area can be added. The selection of the number of functional partitions is a necessary option, while the selection of special functional requirements exists as a recommended option.

[0044] After obtaining the functional zoning model, the tissue structure in the horizontal knitting tissue library 16 is matched and adjusted accordingly. First, the horizontal knitting tissue library 16 determines the minimum outer layer protection (anti-cutting) level and inner layer protection (warmth and cold protection) level required for each partition according to the requirements of the functional zoning model. Secondly, the anti-cutting ability and warmth retention ability data of each tissue in the tissue library 16 are evaluated, and the tissues that meet or exceed the minimum capability requirements of each partition are screened out, and the outer layer protection function level and the inner layer protection function level are sorted in descending order. Priority is given to matching tissues with high priority levels to ensure that key areas are optimally protected. The horizontal knitting tissue can achieve a multi-layer structure, the outer layer is realized by UHMWPE yarn to achieve the outer layer protection function, the inner layer is realized by the warm type yarn to achieve the inner layer protection function, and the middle layer improves the air layer to further prevent cold and keep warm. If the proportion of warm yarn is too high, the anti-cutting function will be reduced. The functional zoning of the abdomen requires high outer layer protection and high inner layer protection, so it is necessary to match the tissue that is balanced and coordinated in these two functions, give priority to the priority (outer layer protection) requirements, and appropriately adjust the inner layer protection requirements to reduce the level.

[0045] S4: Functional partition template.

[0046] Figure 6A functional zoning model diagram of an exemplary embodiment of the present invention is shown. According to the above-mentioned functional zoning principle, a detailed functional zoning template can be obtained. Subsequently, according to the actual requirements of consumers, after the functional zoning processing logic S3, a protective clothing functional zoning template that can be developed is obtained, and then the corresponding horizontal knitting organization structure is matched to complete the functional zoning modular design. The obtained protective clothing functional zoning model has 11 protective functional zones and 2 special functional zones, a total of 13 zones. According to the functional zoning priority logic, the number with high priority is ranked first; the protection level of the inner and outer layers of the arm is relatively low, so according to the overall priority principle, the outer layer protection level is prioritized and the number is ranked first. In special functional areas such as T1 and T2, special functional zones of any shape can be designed within the area according to the needs of consumers. Finally, 61 is a high outer layer protection and low outer layer protection zone E1I6, 62 is a high outer layer protection and high inner layer protection zone E2I1, 63 is a high outer layer protection and high inner layer protection zone E2I2, 64 is a high inner layer protection and medium outer layer protection zone I1E3, 65 is a high inner layer protection and medium outer layer protection zone I2E3, 66 is a medium inner layer protection and medium outer layer protection zone I3E3, 67 is a medium inner layer protection and medium outer layer protection zone I3E4, 68 is a medium inner layer protection and low outer layer protection zone I4E5, 69 is a medium outer layer protection and low inner layer protection zone E4I6, 610 is a low outer layer protection and low inner layer protection zone E5I5, 611 is a low outer layer protection and low inner layer protection zone E6I6, 612 is a high breathability zone T1, and 613 is a high flexibility zone T2. Various modules can be merged, arranged and combined according to the partition principle to obtain a variety of functional partition models to achieve diversified clothing needs. For the functional partition template S4, the horizontal knitting tissue library 16 lays a suitable tissue structure in the template after horizontal knitting tissue recommendation, tissue matching logic 15 and other steps. For example, in the high outer layer protection and low outer layer protection partition E1I6 in 61, the matching structure is tight and thick, and the proportion of UHMWPE yarn is high; in 62, the high outer layer protection and high inner layer protection partition E2I1 is matched with a tight and thick structure, and the proportion of UHMWPE yarn and warm-keeping yarn is 1:1 to balance the two functions; in 68, the middle inner layer protection and low outer layer protection partition I4E5 is matched with a slightly loose structure and a slightly weaker warm-keeping ability, while providing a certain degree of breathability.

[0047] S5: Modular design verification and application.

[0048] Assume that a consumer's demand is a protective jacket that meets general protection needs, and needs to take into account high flexibility and high breathability requirements to be suitable for outdoor climbing. After analysis, the number of functional partitions roughly determined is 8, that is, 8 functional partitions are divided. Figure 7The functional zoning model of the ergonomic flat-knitted protective jacket is shown. Therefore, based on the zoning processing principle S2, when the number of functional zones is less than 13, the zones need to be merged. First, it can be determined that the high breathability zone module 51 and the high flexibility zone module 52 are retained to meet the flexibility and heat and humidity requirements; the high flexibility module 52 is only divided at the elbow, and the shoulder activity area is solved by the style version. Secondly, the zones with the largest difference in protection level are temporarily retained, including the 61 module of the chest, which has a high outer protection level and a low inner protection level, and the 62 module of the abdomen, which has a high inner and outer protection level. The remaining 9 zones are merged into 4 zones, and the modules with similar priority levels are merged in pairs according to the principle of balance. The 63 module of the waist, the 64 module of the lower abdomen, and the 65 module of the hip side have similar protection levels, all of which belong to the high inner protection level and the middle outer protection level. They can be merged, and the levels I1 and I2 are merged into I1. Since the lower abdomen takes priority over the inner layer protection level, it is necessary to dynamically adjust the protection level of the 63 modules of the waist, and lower the outer layer protection level of the 63 modules of the waist, so that the final partition here is 73 high outer layer medium inner layer protection I1E3. The upper arms and forearms are merged with the outer layer protection level priority to obtain 76 low outer layer low inner layer protection area E5I5. Next, the inner layer protection levels of the back and buttocks are consistent, and the outer layer protection levels are close, so they can be merged without adjusting the protection level, and merged into 74 medium inner layer medium outer layer protection area I3E3. Finally, the front shoulder and head are merged. The general principle is to give priority to the outer layer protection level, so the outer layer protection level of the 68 medium inner layer protection low outer layer protection partition I4E5 of the head is adjusted to E4. There is a big difference in the inner protection levels, so these two modules are adjusted to each other, and the inner protection level of the front shoulder 69 is increased, and the level of the head 68 is lowered to I4E5, that is, to I5, and finally 75 is obtained, which is the medium inner protection low outer protection zone E4I5.

[0049] In the embodiment of the present invention, the module connection of the module functional partition, that is, the sewing method of the garment pieces is to use two methods: hot pressing molding and adding / overlapping needle technology.

[0050] The flat knitting tissue library matches the best 8 tissues based on the functional zoning model. The basic parameters of fabrics of various tissue structures, including yarn configuration and functional data, are shown in Table 1. They all meet the protection level required by the zoning, and because they are knitted tissues, they have certain air permeability.
