Description

Technical Field

[0001] This invention belongs to the field of knitting, and more specifically, this invention relates to a translucent jacquard fabric with a dense knit structure and its knitting method. Background Technology

[0002] In the knitting industry, to achieve a noticeable light transmission effect in certain areas of the fabric, it is common practice to perform openwork knitting, such as "picking up stitches" or "empty stitches," on designated areas of the fabric. This method requires shifting and decreasing stitches in the openwork area, which is time-consuming and imposes various restrictions on the pattern shape and jacquard process. The resulting fabric contains floating threads and has a hole-like feel, resulting in a rough and unnatural light transmission effect.

[0003] Conventional close-knit jacquard weaving is based on a pattern. During the jacquard weaving process, the jacquard yarns in each pattern row are made to show and hide corresponding loops to achieve the jacquard effect. Typically, each pattern row has jacquard yarns that interweave and obscure each other, which reduces the light transmission effect due to the obstruction of the light-transmitting yarn loops. In addition, conventional openwork weaving methods also result in a large number of various yarn floats crossing across the fabric, greatly reducing light transmission. The overall fabric becomes messy, holey, uneven, and lacks a consistent style.

[0004] Therefore, conventional methods can no longer meet designers' requirements for the breathable effect of knitted garments. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a method for weaving a light-transmitting jacquard fabric with a dense needle structure. The fabric woven using this method is a non-perforated light-transmitting jacquard fabric with natural and subtle light transmission, unique effect, and convenient weaving.

[0006] The technical solutions for achieving the above-mentioned objectives include the following.

[0007] A first aspect of the present invention provides a method for knitting a translucent jacquard fabric with a close-knit structure, using a computerized flat knitting machine including a first needle bed and a second needle bed, comprising the following steps:

[0008] (1) Design a target pattern, the target pattern including 1 light-transmitting area and N dense areas; a pattern row of the light-transmitting area includes 1 light-transmitting row woven with light-transmitting yarn jacquard and X dense rows woven with dense yarn through; a pattern row of the dense area includes X dense rows woven with dense yarn jacquard and 1 light-transmitting row woven with light-transmitting yarn through;

[0009] (2) The jacquard weave described in step (1) involves weaving the weft direction of the jacquard weave together to form a basic jacquard and output the basic jacquard.

[0010] (3) Simultaneously move and merge the light-transmitting rows in all flower pattern rows in the light-transmitting area and the dense area, so that the 1st, 1*3+1st, 2*3+1st, 3*3+1st, 4*3+1st... flower pattern rows include light-transmitting rows;

[0011] (4) Make the pattern data and weave it to get the result.

[0012] In a second aspect, the present invention provides a translucent jacquard fabric with a dense knit structure obtained by the above-described weaving method.

[0013] The knitting method of the translucent jacquard fabric with a dense needle structure in this invention is based on the pattern area and is obtained by conventional computer flat knitting machine with a first needle bed and a second needle bed. By selecting a transparent or extremely fine yarn material as the translucent yarn and knitting it with other tightly knitted yarns, combined with a specific jacquard process, the translucent yarn loops occupy more of the knitting surface, expanding the local translucent surface, maintaining sparseness, increasing the gap between loops, reducing the interference of other yarns passing through and crossing, thereby making the fabric locally translucent (translucent area).

[0014] The jacquard fabric with a dense needle structure woven by this invention has a significant light-transmitting effect in some areas compared with conventional openwork methods such as openwork and hollow needle. The light-transmitting area is flat and natural, and the light-transmitting row has a uniform loop structure without any hole-like feeling. It greatly reduces the obstruction of the dense row yarns passing through and intersecting, which is completely different from the style of conventional openwork light-transmitting effect, and can provide more effect options for the design of such knitted products.

[0026] To facilitate understanding of the present invention, a more complete description will be provided below. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0028] The present invention discloses a light-transmitting jacquard fabric with a dense needle structure, which is obtained by conventional computer flat knitting machine with front and back needle beds (in this article, front needle bed and first needle bed refer to the same thing, and back needle bed and second needle bed refer to the same thing), and consists of light-transmitting areas (transmitting light) and dense areas (not transmitting light).

[0029] The "translucent jacquard fabric" mentioned in this invention refers to a fabric with a certain degree of light transmission in local areas, distributed in patterned areas, presenting a kind of light transmission and interweaving of solid and void patterns, which has a certain light transmission visual effect.

[0030] The "dense needle structure" mentioned in this invention refers to the fabric structure obtained by simultaneously full needle knitting on the front and rear needle beds of a computerized flat knitting machine.

[0031] The "jacquard with dense needle structure" described in this invention includes, but is not limited to, "sesame base jacquard", "air layer jacquard", and "four-flat floating line jacquard".

[0032] In this invention, "translucent yarn" refers to a transparent or extremely fine yarn (including but not limited to chemical fibers, cotton, silk, animal fibers, etc.) with a yarn ply count of less than or equal to 1 / 40 (1 ply 40 count). For example, if 2 / 120 < 1 / 40, then 2 / 120 meets the requirements for translucent yarn. "Compact yarn" in this invention refers to a yarn with a yarn ply count greater than 1 / 40 (1 ply 40 count).

[0033] The “four-needle flat knit structure” mentioned in this invention refers to a rib flat knit structure in which the front and back needle beds are simultaneously fully knitted.

[0034] The knitting method of the translucent jacquard fabric with a dense needle structure of the present invention first involves creating pattern data in computer flat knitting machine pattern software according to the target pattern requirements. The target pattern is first output as a basic jacquard pattern, which includes one corresponding translucent color area (hereinafter referred to as the translucent area) and N corresponding dense color areas (hereinafter referred to as the dense area). The jacquard weft of the two areas is mutually converted and connected in series to form the basic jacquard pattern. The translucent area is woven with a four-flat float jacquard structure, while the dense area is woven with an arbitrary dense needle structure jacquard structure. Within each pattern row, the translucent area includes: using translucent yarn to knit a sparse four-flat needle structure, forming one row of translucent loops, occupying the first and second needle beds; using dense yarn to knit one loop-interval float thread that passes through the second needle bed, for a total of X dense rows; the dense area includes: using dense yarn to knit an arbitrary dense needle structure jacquard structure, occupying the first and second needle beds, for a total of X dense rows; using translucent yarn to knit one translucent row that is hidden in the second needle bed.

[0035] In the target pattern, one pixel row equals one pattern row. Based on the weaving settings of the light-transmitting area, a complete pattern row contains one processing row (referred to as a "light-transmitting row" in this text) woven from light-transmitting yarns (transparent or extremely fine yarns). The light-transmitting row within the first pattern row is called the first light-transmitting row, the light-transmitting row within the second pattern row is called the second light-transmitting row, and so on; the light-transmitting row is a four-panel float jacquard structure. One loop-interval float is woven with tightly packed yarns and passes through the second needle bed, resulting in X processing rows (referred to as "tight rows" in this text). This provides the basic jacquard data for the light-transmitting area. It can be observed that each light-transmitting row in the light-transmitting area is partially obstructed by the tightly packed yarns, reducing its light transmittance.

[0036] In the basic jacquard pattern, all the translucent rows within the translucent and densely woven areas are moved, merged, and rearranged using a "2-to-1" method (merging two translucent rows after the previous translucent row). That is, the second and third translucent rows are moved and merged after the first translucent row within the first pattern row. At this point, the first pattern row contains three translucent rows: the first, second, and third translucent rows. The original second and third pattern rows no longer contain translucent rows, only the densely woven row structure. Similarly, the fifth and sixth translucent rows are moved and merged after the fourth translucent row within the fourth pattern row. At this point, the fourth pattern row contains three translucent rows: the fourth, fifth, and sixth translucent rows. The original fifth and sixth pattern rows no longer contain translucent rows, only the densely woven row structure. Following this pattern, the first, fourth, seventh, tenth, and so on rows of the basic jacquard are all moved and merged in the above manner to obtain the final target pattern data. Clearly, after the above movement and merging of the translucent rows, the original basic jacquard, where each pattern row was woven with one translucent row, is transformed into only the first, fourth, seventh, tenth, and so on rows including the translucent rows, with each row woven with three translucent rows.

[0037] Based on the above settings, the dense area is thick, tight, and opaque; because the three rows of light-transmitting rows (four-stitch) in the light-transmitting area are close to each other, forming segmented clusters, the obstruction by the dense row yarns is greatly reduced, and a larger sparse area is formed locally, which indirectly expands the light-transmitting surface of the fabric and ensures that the light-transmitting area has good light transmittance.

[0038] In some embodiments of the present invention, a method for knitting a translucent jacquard fabric with a close-knit structure is disclosed, using a computerized flat knitting machine including a first needle bed and a second needle bed, comprising the following steps:

[0039] (1) Design a target pattern, the target pattern including 1 light-transmitting area and N dense areas; a pattern row of the light-transmitting area includes 1 light-transmitting row woven with light-transmitting yarn jacquard and X dense rows woven with dense yarn through; a pattern row of the dense area includes X dense rows woven with dense yarn jacquard and 1 light-transmitting row woven with light-transmitting yarn through;

[0040] (2) The jacquard weave described in step (1) involves weaving the weft direction of the jacquard weave together to form a basic jacquard and output the basic jacquard.

[0041] (3) Simultaneously move and merge the light-transmitting rows in all flower pattern rows in the light-transmitting area and the dense area, so that the 1st, 1*3+1st, 2*3+1st, 3*3+1st, 4*3+1st... flower pattern rows include light-transmitting rows;

[0042] (4) Make the pattern data and weave it to get the result.

[0043] In some embodiments, in step (3), the first, the first*3+1, the second*3+1, the third*3+1, the fourth*3+1... flower pattern rows all include 3 rows of light-transmitting rows.

[0044] In some embodiments, X in step (1) is an integer greater than or equal to 1.

[0045] In some embodiments, X in step (1) is an integer greater than or equal to 2.

[0046] In some embodiments, X in step (1) is 2 or 3.

[0047] In some embodiments, X in step (1) is 2.

[0048] In some embodiments, the number of yarn strands in the light-transmitting yarn described in step (1) is less than or equal to 1 / 40.

[0049] In some embodiments, the light-transmitting yarn in step (1) is a chemical fiber, cotton, silk, or animal fiber.

[0050] In some embodiments, the number of yarn strands in the compact yarn described in step (1) is greater than 1 / 40.

[0051] In some embodiments, the method of weaving a pattern row of the light-transmitting area in step (1) is as follows: using light-transmitting yarn to weave a four-flat floating jacquard structure to form a row of light-transmitting loops, which occupy the first needle bed and the second needle bed; using tight yarn to weave a loop-interval floating line, which weaves X rows in total and passes through and is hidden in the second needle bed.

[0052] In some embodiments, the method for weaving a pattern row in the dense region of step (1) is as follows: a dense jacquard structure is woven using dense yarn, occupying the first and second needle beds, for a total of X rows, and a translucent row is woven through using translucent yarn, and hidden in the second needle bed.

[0053] In some embodiments, the dense needle structure jacquard weave is a sesame-based jacquard, an air-layer jacquard, or a four-flat floating thread jacquard.

[0054] In other embodiments of the present invention, a light-transmitting jacquard fabric with a dense knit structure obtained by the above-described weaving method is disclosed.

[0055] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Example 1: Weaving method of light-transmitting jacquard fabric with dense needle structure

[0057] Please refer to Figures 2-5 This embodiment provides a method for weaving a light-transmitting jacquard fabric with a close-knit structure, including the following steps:

[0058] 1. Determine the target pattern ( Figure 2 It contains three color areas: A, B, and C, and the pattern size is 220 pixels * 300 pixels.

[0059] 2. Determine the three types of yarns a, b, and c for weaving the three color areas A, B, and C respectively. Yarn a is a light-transmitting yarn, using 1 / 80 of 100% silk, 1 yarn; yarns b and c are compact yarns, using 2 / 30 of 100% cotton (different colors), 1 yarn each.

[0060] 3. Create pattern data in the computerized flat knitting machine pattern software.

[0061] (1) First, perform basic jacquard output, in which each pattern row consists of 2+1=3 process rows. Figure 3 Area A is a translucent area, featuring a four-ply floating jacquard pattern. Each pattern row within this area is woven with yarn a, using one row of sparse four-ply stitches to form a translucent loop that occupies both the front and back needle beds. Yarns b and c are each woven with one loop spaced 11 floats wide, running through the back needle bed, for a total of two rows. Areas B and C are denser areas, both featuring a sesame-based jacquard pattern. Each pattern row within these areas is woven with yarns a, b, and c. The jacquard surface of area B is woven with yarn b for one row, and the jacquard surface of area C is woven with yarn c for one row. Yarn a runs through both areas B and C for one row, hidden within the back needle bed. The jacquard patterns (i.e., four-ply floating jacquard and sesame-based jacquard) in the translucent and denser areas are interwoven and converted in the weft direction to form the basic jacquard pattern.

[0062] (2) In the basic jacquard, all the light-transmitting rows in the two areas are merged into a "2-to-1" arrangement. The light-transmitting rows, which were originally one row per pattern row in the basic jacquard, are now only included in the 1st, 4th, 7th, 10th... pattern rows, and each pattern row includes 3 light-transmitting rows. Figure 4 ).

[0063] 4. Input the pattern data into a computerized flat knitting machine (in this example, a STOLL CMS530-7.2 model is used). Yarn a is red yarn, yarn b is yellow yarn, and yarn c is red yarn for knitting to obtain a translucent jacquard fabric with a dense needle structure (see...). Figure 5 ).

[0064] from Figure 5 It can be clearly seen that area A has a significant light transmission effect. The light transmission area is flat and natural, and the light transmission coil structure is uniform, without any hollow feeling.

[0065] Example 2: Weaving method of light-transmitting jacquard fabric with dense needle structure

[0066] Please refer to Figures 6-9 This embodiment provides a method for weaving a light-transmitting jacquard fabric with a close-knit structure, including the following steps:

[0067] 1. Determine the target pattern ( Figure 6 It contains three color areas: A, B, and C, and the pattern size is 220 pixels * 300 pixels.

[0068] 2. Determine two types of yarn, a and b, for weaving the three color areas A, B, and C respectively. Yarn a is a light-transmitting yarn, using 1 / 90 of 100% silk, one strand; yarn b is a compact yarn, using 2 / 28 of 100% wool, one strand.

[0069] 3. Create pattern data in the computerized flat knitting machine pattern software.

[0070] (1) First, perform basic jacquard output, in which each pattern row consists of 3+1=4 process rows. Figure 7 Area A is a translucent area, featuring a four-ply floating jacquard pattern. Each pattern row within this area is woven with yarn a, using one row of sparse four-ply stitches to form a translucent loop that occupies both the front and back needle beds. Yarn b is woven with one loop spaced 11 counts wide, running through the back needle bed, for a total of three rows. Areas B and C are denser areas. Area B features a sesame-based jacquard pattern, while area C features an air-layer jacquard pattern. Each pattern row within these areas is woven with both yarns a and b. The jacquard surface in both areas is woven with yarn b for three rows, while yarn a runs through both areas for one row, hidden within the back needle bed. The jacquard patterns in these translucent and denser areas (i.e., four-ply floating jacquard, sesame-based jacquard, and air-layer jacquard) are interwoven and converted in the weft direction to form the basic jacquard pattern.

[0071] (2) In the basic jacquard, all the light-transmitting rows in the two areas are merged into a "2-to-1" arrangement. The light-transmitting rows, which were originally one row per pattern row in the basic jacquard, are now only included in the first, fourth, seventh, tenth... pattern rows, and each pattern row includes three light-transmitting rows. Figure 8 ).

[0072] 4. Input the pattern data into a computerized flat knitting machine (in this example, a STOLL CMS530-7.2 model is used). Yarns a and b are white yarns, and the finished product, a translucent jacquard fabric with a dense needle structure, is obtained (see...). Figure 9 ).from Figure 9 The translucent jacquard pattern is clearly visible, and the translucent area is flat, natural, and the translucent coil structure is uniform.

[0073] See the illustration showing the effect of applying the translucent jacquard fabric of this embodiment to clothing products. Figure 10 and Figure 11 It can be seen that the light-transmitting areas are sparse and the gaps between the coils are large, allowing light to pass through significantly; the dense areas are thick, compact, and opaque.

[0074] Comparative Example 1

[0075] The weaving method of this comparative example is the same as that of Example 1, except that step (2) is: in the basic jacquard, all the light-transmitting rows in the two areas are arranged in a "3-to-1" combination. The light-transmitting rows are changed from each pattern row in the original basic jacquard to only the 1st, 5th, 9th, 13th... pattern rows include light-transmitting rows, and each includes 4 light-transmitting rows.

[0076] Using the weaving method described in this comparative example, because the light-transmitting rows in the light-transmitting area are woven in 3+1=4 rows, the tightly packed rows are separated by these 4 light-transmitting rows. The light-transmitting rows are easily lifted and loops are missed, while the tightly packed rows are severely taut and prone to yarn breakage. Therefore, this weaving method is very difficult and hard to implement.

[0077] Comparative Example 2

[0078] The weaving method of this comparative example is the same as that of Example 1, except that step (2) is: in the basic jacquard, all the light-transmitting rows in the two areas are arranged in a "1-to-1" combination. The light-transmitting rows are changed from each pattern row in the original basic jacquard to only the 1st, 3rd, 5th, 7th... pattern rows include light-transmitting rows, and each includes 2 light-transmitting rows.

[0079] Using the weaving method described in this comparison, an effective light transmission effect cannot be achieved due to insufficient light-transmitting rows.

[0080] Comparative Example 3

[0081] This comparative example uses conventional methods such as "picking stitches" or "empty stitches" to create openwork weave in designated areas (transparent areas) of the fabric. The finished product is as follows: Figure 12 As shown.

[0082] from Figure 12 It can be seen that the resulting fabric has a large number of floating yarns of various types, which greatly reduces light transmission and makes the fabric overall messy, with a holey feel. The light transmission effect is rough and unnatural, and it is also uneven and has a monotonous style.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
