Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to an infant textile fabric and its production method. Background Technology

[0002] Multi-layered fabrics offer increased thickness, providing greater protection for infants and young children while meeting the textile industry's need for softness. The basic weave selection for multi-layered fabrics is relatively simple. When the average float lengths of each basic weave are equal or nearly equal, the shrinkage rate of each layer is similar, ensuring a smooth fabric surface and successful weaving.

[0003] However, in actual production, multi-layered fabrics often face problems such as large bending variations in the joining yarns and uneven fabric surfaces due to differences in the joining methods. Some literature points out that multi-layered plain weave should not exceed four layers, otherwise it is difficult to complete the weaving. This limits the increase in the thickness of multi-layered fabrics, and six-layer plain weave fabrics have uneven surfaces. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an infant textile fabric and its production method, solving the technical problem of unevenness in the surface of 6-layer plain weave fabric in the prior art.

[0010] In any implementation, the warp density is 689 threads / 10cm, the weft density is 689 threads / 10cm, and the fabric width is 208cm.

[0011] Furthermore, this invention also proposes a method for producing the aforementioned infant textile fabric, comprising a warping process, a sizing process, a reed threading process, and a weaving process in sequence; in the reed threading process, a 111.33-tooth / 5.08cm steel reed is used, with 3 threads per reed; the ground heddles are threaded in the heddle frames on pages 1-17, with the threading method being (1.2.3.4.5.6.7.8.9.10.11.12)×5+(1.2.3.4.5.6.7)+13.9.10.11.12+

(1.2.3.4.5.6.7.8.9.10.11.12)×5+(1.2.3.4.5.6.7.8.9.10.11)+17

[0015] Compared with the prior art, the beneficial effects of the present invention include: the applicant has discovered through research that the main reason for the formation of a honeycomb structure in multi-layer fabrics is the unreasonable weft insertion sequence. By changing the weft insertion sequence and adopting a loose splicing, the honeycomb structure can be mitigated. The fabric is composed of multiple layers of plain weave, with both warp and weft yarns being organic cotton. The fabric is a 6-layer plain weave fabric, composed of 6 systems of warp and weft yarns, woven into a 6-layer plain weave structure on the same machine. The yarn count of the 1st and 2nd layers and the 5th and 6th layers is relatively fine, while the yarn count of the 3rd and 4th layers is relatively coarse. The 6 layers of plain weave fabric are connected by the lower layer of warp yarns to the upper layer of weft yarns. This method can effectively improve the flatness of the fabric surface and solve the problem of uneven fabric surface in traditional 6-layer plain weave fabrics. Attached Figure Description

[0027] The "range" disclosed in this application is defined by a lower limit and an upper limit. A given range is defined by selecting a lower limit and an upper limit, which define the boundaries of a particular range. Ranges defined in this way can include or exclude endpoints and can be arbitrarily combined; that is, any lower limit can be combined with any upper limit to form a range. For example, if ranges of 60~120 and 80~110 are listed for a specific parameter, it is also expected that ranges of 60~110 and 80~120 are also included. Furthermore, if minimum range values ​​of 1 and 2 are listed, and if maximum range values ​​of 3, 4, and 5 are listed, then the following ranges are all expected: 1~3, 1~4, 1~5, 2~3, 2~4, and 2~5. In this application, unless otherwise stated, the numerical range "a~b" represents a shortened representation of any combination of real numbers between a and b, where a and b are real numbers. For example, the numerical range "0~5" indicates that all real numbers between "0~5" have been listed in this article; "0~5" is simply a shortened representation of these numerical combinations. Furthermore, when a parameter is stated as an integer ≥2, it is equivalent to disclosing that the parameter is, for example, an integer such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

[0028] Unless otherwise specified, the terms "comprising" and "including" as used in this application can be open-ended or closed-ended. For example, "comprising" and "including" can mean that other components not listed may also be included, or that only the listed components may be included.

[0029] Unless otherwise specified, the term "or" is inclusive in this application. For example, the phrase "A or B" means "A, B, or both A and B". More specifically, the condition "A or B" is satisfied by any of the following conditions: A is true (or exists) and B is false (or does not exist); A is false (or does not exist) and B is true (or exists); or both A and B are true (or exist).

[0030] This specific embodiment provides an infant textile fabric, which is composed of multiple layers of plain weave, with both warp and weft yarns made of organic cotton. The fabric is a 6-layer plain weave fabric, consisting of 6 systems of warp and weft yarns woven on the same machine to form a 6-layer plain weave structure. The yarn counts of layers 1 and 2, and layers 5 and 6 are finer, while the yarn counts of layers 3 and 4 are coarser. The 6 layers of plain weave fabric are connected by the lower layer's warp yarns to the upper layer's weft yarns. The joints between layers 1, 2, 3, 4, 5, and 6 are... The method is as follows: the 2nd layer connects to the 1st layer, the 3rd layer connects to the 2nd layer, the 4th layer connects to the 3rd layer, the 5th layer connects to the 4th layer, and the 6th layer connects to the 5th layer. There are a total of 5 joints in the 6 layers of plain weave. During the weaving process, the weft insertion sequence is: front weft - middle weft 1 - middle weft 2 - middle weft 3 - middle weft 4 - middle weft 5 - inner weft - middle weft 5 - middle weft 4 - middle weft 3 - middle weft 2 - middle weft 1 - front weft. During the weaving process, the selvage is threaded through the 1.2 heddle frames, and one heddle thread is threaded through two warp yarns, adopting a three-up-three-down weave structure.

[0031] In some embodiments, the above-mentioned infant textile fabric has the following warp yarns: 14.8tex compact spun organic cotton; weft yarns: 14.8tex compact spun organic cotton A and 36.4tex air-jet spun organic cotton B; weft yarn ratio: 8:4; warp density 689 ends / 10cm, weft density 689 ends / 10cm, and fabric width 208cm.

[0032] In addition, the present invention also proposes a method for producing the above-mentioned infant textile fabric, which includes a warping process, a sizing process, a reed threading process and a weaving process in sequence. In the warping process, the warp yarns are warped, with 14,292 warp ends, 18 warp beams, and 794 warp yarns per row. The warp beam width is 2198 mm, and the warping speed is 500 meters per minute. In the sizing process, the sizing formula consists of high-performance modified starch PRS-C 37.5kg / barrel, GR-796 37.5kg / barrel, edible corn starch 50kg / barrel, polyacrylic acid 10kg / barrel, DH68 3kg / barrel, and NL-4 0.2kg / barrel. The sizing is prepared using the volumetric method; at a volume scale of 1000cm³, the sizing viscosity is 6.3-6.5 seconds, the solids content is 11.3%, the soaking time is 20-30 minutes, the sizing machine speed is 100 meters / minute, and the sizing moisture regain is 6.5%. In the sizing process, the sizing formula consists of high-performance modified starch PRS-C 37.5kg / barrel, GR-796 37.5kg / barrel, edible corn starch 50kg / barrel, polyacrylic acid 10kg / barrel, DH68 3kg / barrel, and NL-4 0.2kg / barrel. The sizing is prepared using the volumetric method; at a volume scale of 1000cm³, the sizing viscosity is 6.3-6.5 seconds, the solids content is 11.3%, the soaking time is 20-30 minutes, the sizing machine speed is 100 meters / minute, and the sizing moisture regain is 6.5%. In the reed threading process, a 111.33-tooth / 5.08cm steel reed is used, with 3 threads per reed; the ground heald is threaded through the heald frame on pages 1-17, using the following threading method: (1.2.3.4.5.6.7.8.9.10.11.12)×5+(1.2.3.4.5.6.7)+13.9.10.11.12+

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] In this invention, the terms "some embodiments," "this embodiment," and examples are used to describe a subset of all possible embodiments. However, it is understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0035] If the application documents contain similar descriptions such as "first / second", the following explanation shall be added: In the following description, the terms "first / second / third" are used only to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0036] In this embodiment, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, object A and / or object B can represent three situations: object A exists alone, object A and object B exist simultaneously, and object B exists alone.

[0037] The following describes embodiments of this application. The embodiments described below are exemplary and are only used to explain this application, and should not be construed as limiting this application. Where specific techniques or conditions are not specified in the embodiments, they are performed according to the techniques or conditions described in the literature in this field or according to the product instructions. Reagents or instruments used, unless otherwise specified, are all conventional products that can be obtained commercially.

[0038] Example 1 This embodiment presents an infant textile fabric, which is produced by the following steps: 1. Select the 1st, 2nd, 3rd, 4th, 5th, and 6th layers of plain weave as follows: Figure 2 .like Figure 2 As shown, in the plain weave structure cycle, there are two warp yarns and two weft yarns, with one warp weave point and one weft weave point. The warp weave point is represented by the symbol " ", and the weft weave point is represented by the symbol " ". The table shows the first layer of a 6-layer plain weave, with the first warp yarn designated J11, the second warp yarn designated J12, the first weft yarn designated W11, and the second weft yarn designated W12.

[0039] 2. The original 6-layer plain weave structure without joints, as shown below. Figure 8 .like Figure 8 As shown, six basic plain weave structures are layered together to form six layers of plain weave. During the layering process, the warp and weft points of the fabric structure can be gradually depicted. For example, when layering basic plain weave structures, the basic weave points of the first layer are depicted first, with one warp point represented by the symbol "☐" and one weft point by the symbol "☐". Then, the basic weave points of the second layer are depicted, with one warp point represented by the symbol "☐" and one weft point by the symbol "☐". This process continues until all six basic weave structures have been depicted. Figure 8As can be seen, the six basic weave points form a diagonal line. After drawing the basic weave points for the six plain weave layers, the layering points are filled in, represented by the symbol "○". The warp and weft yarn arrangement ratios for layers 1-6 are set to 1:1:1:1:1:1 respectively. When weaving the second layer, both warp yarns J11 and J12 of the first plain weave layer are lifted. Therefore, when we cast the first and second weft yarns of the second plain weave layer, the two warp yarns of the first plain weave layer are drawn as the layering points, which are the layering points for the first and second layers, represented by the symbol "○". Similarly, when weaving the third plain weave layer, the warp yarns of the first and second plain weave layers all belong to the upper layer and need to be drawn as warp weave points, until the sixth plain weave layer. The warp yarns of the first, second, third, fourth, and fifth plain weave layers all belong to the upper layer and need to be drawn as warp weave points. There are a total of 12 warp yarns and 12 weft yarns in the six plain weave layers.

[0040] 3. The conversion of the original 6-layer plain weave structure without joints, such as... Figure 3 .like Figure 8 As shown, the original 6-layer plain weave without seams forms a honeycomb pattern, resulting in an uneven fabric surface. This is because during the weaving process, as the weft insertion sequence increases from the 1st to the 12th weft, the number of warp yarns lifted increases from 1 to 6, gradually increasing the tension on the loom. This tension reaches its maximum at the 6th weft, and then suddenly returns to the minimum warp tension. After the conversion, as shown... Figure 3 As shown, the number of warp yarns that need to be lifted in the fabric is the same, but by using a method from small to large and then from large to small, the tension on the machine is more stable, resulting in a better fabric surface.

[0041] 4. Design the location of the joints to obtain a complete 6-layer plain weave structure, as shown below. Figure 5 The 6-layer plain weave structure (excluding seams) uses a bottom-to-top joining method, where the warp yarns of the lower plain weave layer are joined to the weft yarns of the upper plain weave layer, forming warp seams. There are 5 seams: one seam between layers 1 and 2, one between layers 2 and 3, one between layers 3 and 4, one between layers 4 and 5, and one between layers 5 and 6. Plot these seams on the weave diagram using the symbol "▲".

[0042] 5. Simplify the 6-layer plain weave structure as follows: Figure 5 get Figure 1 .like Figure 1 As shown, due to the organization Figure 5 The majority of the 6-layer plain weave warp yarns, excluding seams, are represented by 1 to 12. The 5 seams are represented by 13, 14, 15, 16, and 17. The positions of the seams correspond one-to-one with the warp and weft yarn repeating sequence. During simplification, the number of yarns and the repeating sequence must be filled in completely according to the corresponding positions.

[0043] 6. The position of the joint point of the 6-layer plain weave structure after simplifying the warp yarn cycle is as follows: Figure 9 .like Figure 9As shown, when 6 layers of plain weave do not require splicing, the pattern of changes in warp and weft weave points is that the maximum change is 12 threads / cycle, meaning that the weaving process requires 12 heald frames. The order of heald threading controls heald lifting, and the order of weft insertion controls the weft yarn. After splicing, 5 heald frames participate in heald lifting, for a total of 17 heald frames. The spliced ​​heald frames are threaded in front, and the unspliced ​​heald frames are threaded in the back.

[0044] The process parameters for the 6-layer plain weave fabric in this embodiment are as follows: 1. Warp yarn: 14.8tex compact organic cotton; Weft yarn: Weft A: 14.8tex compact organic cotton; Weft B: 36.4tex air-jet spun organic cotton. Weft A:Weft B = 8:4. Warp density: 689 ends / 10cm; Weft density: 689 ends / 10cm; Fabric width: 208cm; Reed number: 111.33 teeth / 2 inches; Number of threads: 3; Total warp ends: 14292; Reed width: 217.8cm; Yarn consumption per 100m: Warp yarn 22g / 100m, Weft A yarn consumption 15.25g / 100m, Weft B yarn consumption 19.01g / 100m.

[0045] 2. Warping process: The warp yarn is made of 14.8 tex organic cotton, with 794 rows, 18 warp beams, a warping speed of 500 m / min, and a warp beam width of 2198 mm.

[0046] 3. Sizing Process: Sizing Formula: High-performance modified starch PRS-C 37.5kg / barrel, GR-796 37.5kg / barrel, edible corn starch 50kg / barrel, polyacrylic acid 10kg / barrel, DH68 3kg / barrel, NL-4 0.2kg / barrel. Sizing Process: The sizing is prepared using a constant volume method. At a volume scale of 1000cm³, the sizing viscosity is 6.3-6.5 seconds, and the solid content is 11.3%. The sizing component is mainly starch sizing, making it relatively environmentally friendly for sizing organic cotton. The sizing time should not be too long, ideally 20-30 minutes. Therefore, it is necessary to improve the quality awareness of the sizing machine operators to ensure the fluidity of the sizing solution. Good fluidity allows the sizing solution to have a certain degree of penetration into the warp yarns under medium pressure drop, thereby improving the sizing strength. The sizing machine speed is 100 meters / minute, and the sizing moisture regain is 6.5%, slightly higher than the viscosity in the sizing barrel.

[0047] 4. Reed threading process: Thread the reed according to the pattern diagram, which is derived from the fabric structure. The structure diagram for a 6-layer plain weave is shown below. Figure 1The warp yarns from the 1st to the 12th are a 6-layer plain weave without any knots. There are 12 * 5 = 60 warp yarns in 5 cycles of this 6-layer plain weave. The knotting warp yarns are the 13th, 14th, 15th, 16th, and 17th warp yarns, which, together with the repeating warp yarns 1, 2, 3, 4, 5, 6, and 7, form the knotting layer. During the weft insertion, the inner warp yarns are lifted and interweave with the outer weft once, forming a warp weave point. For the remaining time, they interweave according to their corresponding plain weave layer level within the 6-layer plain weave. This can be understood as follows: in the 6-layer plain weave, the first layer of plain weave warp yarns does not interweave with the outer weft, the warp yarns do not increase crimp, the tension on the loom is stable, and the fabric surface is relatively smooth. Looking at the warp direction, the number of warp yarns in any layer of plain weave is 60 + 12 = 72. Therefore, the distance between two adjacent warp yarns is 72 yarns / warp density = 72 ÷ 689 yarns / 10cm = 1.04cm. Similarly, the distance between two adjacent weft yarns is 72 yarns / warp density = 72 ÷ 689 yarns / 10cm = 1.04cm. The difference is that the warp yarn arrangement order of the 6 layers of plain weave is: surface warp yarn surface diameter 1, middle warp first layer 1, middle warp second layer 1, middle warp third layer 1, middle warp fourth layer 1, inner layer warp yarn inner diameter 1, surface warp yarn surface diameter 2, middle warp first layer 2, middle warp second layer 2, middle warp third layer 2, middle warp fourth layer 2, inner layer warp yarn inner diameter 2. To facilitate weaving, the weft yarn arrangement of the 6-layer plain weave is changed to: Outer weft 1, Middle weft layer 1 (first layer), Middle weft layer 2 (second layer), Middle weft layer 1 (third layer), Middle weft layer 4 (fourth layer), Inner weft 1, Inner weft 2, Middle weft layer 4 (second layer), Middle weft layer 3 (second layer), Middle weft layer 2, Middle weft layer 1 (second layer), Outer weft 2. It is easy to see that the warp yarn arrangement of the 6-layer plain weave is 11, 21, 31, 41, 51, 61, 12, 22, 32, 42, 52, 62, which is a sequential arrangement. The weft yarn arrangement of the 6-layer plain weave is 11, 21, 31, 41, 51, 61, 62, 52, 42, 32, 22, 12, which is a mirror image arrangement. For easier understanding, the diagram for each layer of the 6-layer plain weave is as follows. Figure 2 .like Figure 2 As shown, the symbol " "This indicates that the basic weave point of each layer of plain weave is the warp weave point, symbolized by " "This indicates that the base weave point of each plain weave layer is the weft weave point. According to..." Figure 2 It can draw fabric weave diagrams without seams, such as Figure 3 . Figure 3 As shown, put Figure 2 During the process of filling in the warp and weft weave points into the 6-layer plain weave structure, due to the compositional characteristics of the multi-layer weave, the entire outer diameter of the lining layer is raised, becoming the warp weave points, denoted by the symbol "". The horizontal numbers 1 to 12 represent warp yarns, and the vertical numbers 1 to 12 represent weft yarns. The numbers 11, 21, 31, 41, 51, 61, 12, 22, 32, 42, 52, 62 represent the warp yarn arrangement, and the numbers 11, 21, 31, 41, 51, 61, 62, 52, 42, 32, 22, 12 represent the weft yarn arrangement. A diagram of a 6-layer plain weave including a single-joint is shown below. Figure 4 ,like Figure 4 As shown, the basic structure of the 6-layer plain weave consists of 12 warp and weft yarns, symbolized by " "This is the warp weave point formed when the weft is lifted. Therefore, a 6-layer plain weave requires 5 joins, involving a total of 12*5=60 yarns. (Combined weave structure)" Figure 1 Since the warp and weft yarns are joined approximately every 1cm, when the first plain weave layer joins the second, the warp yarns of the second plain weave layer are lifted and interweave with the weft yarns of the first plain weave layer. Based on the fabric density and the interval, the required number of yarns can be calculated as 1cm × 689 yarns / 10cm = 68.9 yarns. Considering that the basic structure of a 6-layer plain weave has 12 yarns, the closest to 68.9 yarns is 72 yarns for a complete 6-layer plain weave. Similarly, when the second plain weave layer joins the third, third, fourth, fifth, and sixth plain weave layers, the number of yarns is always 72. Therefore, a complete 6-layer plain weave structure has 360 warp yarns per cycle, and the same applies to the number of weft yarns per cycle. A complete 6-layer plain weave structure diagram is shown below. Figure 5 ,like Figure 5 As shown, the complete weave diagram of a 6-layer plain weave is simplified to a simplified version because the large number of yarns makes the analysis inconvenient. Figure 1 , Figure 1The visual diagram matching the warp threading sequence can reconstruct the complete weave diagram of a 6-layer plain weave. The warp threading sequence is (1.2.3.4.5.6.7.8.9.10.11.12)*5+(1.2.3.4.5.6.7)+13.9.10.11.12+[(1.2.3.4.5.6.7.8.9.10.11.12)*5+(1.2.3.4.5.6.7.8)+14.10.11.12]+[(1.2.3.4.5.6.7.8.9.10.11.12)*5+ ... 2) *5 + (1.2.3.4.5.6.7.8.9) + 15.11.12】 + [(1.2.3.4.5.6.7.8.9.10.11.12) *5 + (1.2.3.4.5.6.7.8.9.10) + 16.12】 + [(1.2.3.4.5.6.7.8.9.10.11.12) *5 + (1.2.3.4.5.6.7.8.9.10.11) + 17]. When threading the reed, use a 111.33-tooth / 5.08cm steel reed, 3 threads per reed. The threading width = total number of warp threads / reed number / number of threads per reed * coefficient = 14292 / 111.33 / 3 * 5.08 = 217.4cm. Because the selvage is controlled by a separate heald frame, and two warp yarns are threaded through each heald, and because the selvage warp yarns follow a 3 / 3 sinking pattern, the selvage weave diagram is as follows. Figure 6 .like Figure 6 As shown, the selvage is threaded onto the heald frames on pages 18 and 19, using a 3 / 3 weft-weighted plain weave. Because the selvage is a single layer, its shrinkage rate is close to that of the warp yarns in a 6-layer plain weave, allowing for synchronized tension and securing the selvage to the warp yarns, resulting in smoother weaving. Since the waiting time for each warp yarn to complete one weave cycle in a 6-layer plain weave is relatively long, considering the vibration of the fabric surface during weaving, it is recommended to use a heavier stop strip. This ensures the stop strip can fall promptly when the warp breaks and the machine stops. In this case, a 0.2mm thick, 2.12g stop strip is used, providing higher sensitivity during warp breakage and stopping. The stop strips are threaded into the stop strip in the order 11, 22, 33, 44, 55, 66. This double-threading method reduces warp yarn movement caused by fabric surface vibration during weft insertion.

[0048] 5. Weaving process: The weft insertion sequence for the first layer of plain weave is as follows: Figure 7 .like Figure 7As shown in the figure, when the first weft W11 is inserted, it indicates the interweaving of the face weft and the warp yarns. All the warp yarns in the 2nd, 3rd, 4th, 5th, and 6th layers are below. That is, the middle 1 warp yarns J21 and J22, the middle 2 warp yarns J31 and J32, the middle 3 warp yarns J41 and J42, the middle 4 warp yarns J51 and J52, and the backing warp yarns J61 and J62 are all below, a total of 10 warp yarns. Since there is one warp tissue point and one weft tissue point in the interweaving of the face warp and the face weft in the plain weave, the tissue point between the face weft W11 and the face warp J11 is the warp tissue point, and the tissue point between the face weft W12 and the face warp J12 is the weft tissue point. Since the 1st, 2nd, 5th, and 6th layers of the 6-layer plain weave use the weft yarn of organic cotton 14.8 tex, which is represented by the code "A", when inserting the first weft of the face weft W11, the weft selector uses "A". Similarly, when inserting the middle 1 weft W21 in the second weft, the weft selector also uses "A". At this time, the weft yarn W21 is located in the 2nd layer of the 6-layer plain weave, belonging to the middle 1 plain weave. The plain weave above it is the face tissue plain weave 1 / 1, and the plain weave below it is the 3rd, 4th, 5th, and 6th layers. According to the weft insertion characteristics of the multi-layer tissue, when inserting the face weft, the backing warp is below and when inserting the backing weft, the face warp is above. Therefore, for the plain weave of the 2nd layer, when inserting the weft yarn of the 2nd layer plain weave for the warp yarns of the 1st layer plain weave, all are warp tissue points, represented by the symbol "○", and the warp yarns of the 3rd, 4th, 5th, and 6th layer plain weaves are all weft tissue points. So when inserting the second weft to weave the middle 1 weft yarn W21, the face warps J11 and J12 are warp tissue points, that is, "○", and the warp yarns of the middle 2, 3, 4 layers and the backing warp are all weft tissue points, that is, J31 and J32, J41 and J42, J51 and J52, J61 and J62 are all weft tissue points, represented by the symbol "□". Since the 3rd and 4th layers of the 6-layer plain weave use the weft yarn of organic cotton 36.4 tex, which is represented by the code "B", when inserting the third weft of the middle 2 weft W31, the weft selector uses "B". For the 1st layer plain weave, the ratio of the A weft to the B weft is 48:24, which simplifies to A weft:B weft = 6:3. The 1st layer plain weave is inserted with wefts 72 times in total, and the required number of warp yarn cycles is 72. There is a joint point ▲ at the 68th in the warp direction and the 72nd in the weft direction, and the distance to the next joint point is 1.04 cm.

[0049] Similarly, the weft insertion sequence of the 2nd layer plain weave can also be determined, and so on until the 6th layer plain weave.

[0050] In the weaving process, the machine model is ZAX9200 - 230, the reed width of the converted loom is 2278 mm, the loom state weft density is 170 picks per inch, the loom speed is 550 rpm, the back beam position is No. 4 - 0, the停经架位置No.2 - 10 - 0, the综平is 300, the loom state warp tension is 2800, the heddle frame height is 114*2 + 105*4 + 114.116.105.102.105*2 + 120.118.116.114.112.108.110, and the height of the large blade is 140.135.150.145.105.100.66.60. + 95 - 50 straight line. The position of the warp release arm is 310 - down. The warp lifting is as Figure 10 , as Figure 10 As shown: Sub-pattern 1 repeats 5 times for a total of 60 rows; Sub-pattern 2 repeats once for a total of 12 rows; Sub-pattern 1 repeats 5 times for a total of 60 rows; Sub-pattern 3 repeats once for a total of 12 rows; Sub-pattern 1 repeats 5 times for a total of 60 rows; Sub-pattern 3 repeats once for a total of 12 rows; Sub-pattern 1 repeats 5 times for a total of 60 rows; Sub-pattern 4 repeats once for a total of 12 rows; Sub-pattern 1 repeats 5 times for a total of 60 rows; Sub-pattern 5 repeats once for a total of 12 rows; Sub-pattern 1 repeats 5 times for a total of 60 rows; Sub-pattern 6 repeats once for a total of 12 rows; Total 360 rows.

[0052] The performance of the infant textile fabric prepared in Example 1 was compared with that of a commercially available 6-layer gauze, and the results are shown in Table 1.

[0053] Table 1 As can be seen from Table 1, the abrasion resistance and tensile strength of the infant textile fabric prepared in Example 1 are significantly better than those of the commercially available 6-layer gauze.
