Moreover, it solves the serrated feeling and looseness problems that appear at the pattern boundaries in the conventional method, achieving smooth and natural pattern boundaries; at the same time, it also realizes the perfect color-blocking jacquard requirements of the relief effect jacquard fabric.

Description

Technical Field

[0001] The invention belongs to the technical field of knitting, and more specifically, relates to a jacquard fabric with relief effect and a knitting method thereof. Background Art

[0002] In the field of knitting, in order to better display the design requirements of various patterns, a weaving process similar to the relief effect is often used to weave the corresponding patterns or graphics. The common embossed fabric effect is formed by combining single-layer tissue and double-layer tissue. For example, one pattern area is a single-layer tissue (such as single-side - a single-layer structure tissue obtained by full-needle knitting of the front or rear needle bed, floating line single-side - a single-layer structure tissue obtained by 1*1 empty needle staggered knitting of the front or rear needle bed), and the other pattern area is a double-layer tissue (such as Siping - a double-layer structure tissue obtained by full-needle staggered knitting of the front and rear needle beds, sesame bottom - a double-layer structure tissue obtained by full-needle knitting of the front and rear needle beds in a jacquard staggered manner, and the front and back sides of the tissue are connected, air layer - a double-layer structure tissue obtained by full-needle knitting of double-single-side jacquard structure by the front and rear needle beds, and the front and back sides of the tissue are hollow). Due to the difference in tissue and a small thickness difference between the single-layer fabric and the double-layer fabric, the corresponding pattern areas can be distinguished, the double-layer tissue appears flat and slightly raised, and the single-layer tissue appears flat and concave, thus producing a similar embossed effect, but the overall effect is not obvious. And due to the loop-forming characteristics of knitted fabrics, when the single-layer structure and the double-layer structure are converted into each other, the coils at the arc boundary are arranged and bent in a step-by-step manner, with a strong sawtooth feeling. At the same time, the graphic boundaries of the embossed area are relatively loose and of lower quality.

[0003] In addition, common double-layer structures include Siping, Zhimadi, and Air Layer. Due to structural limitations, these structures have flat and monotonous surface effects, lack texture, have a small degree of relief, and are fixed and cannot be adjusted. The difference between single-layer and double-layer structures (single-layer structures cannot hide different-colored yarns, but double-layer structures can) results in the inability to achieve a perfect contrasting jacquard effect between relief pattern areas, i.e., relief different colors (the relief raised area and the sunken area are displayed with different-colored jacquards).

[0004] Therefore, it is necessary to improve the weaving method of the jacquard fabric with embossing effect. Summary of the invention

[0005] Based on this, the object of the present invention is to provide a jacquard fabric with relief effect and a weaving method thereof.

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

[0007] In a first aspect of the present invention, a method for knitting a jacquard fabric with a relief effect is provided, wherein the jacquard fabric comprises an A region and a B region, and is knitted using a knitting device comprising a first needle bed and a second needle bed, comprising the following steps:

[0008] (1). Obtain the first yarn and the second yarn;

[0009] (2). Knit the front side with the first yarn on the first needle bed to obtain 2 rows of first coils. For the first coils in one row, perform tuck knitting on 1 needle position of the second needle bed at an interval of 1+N needles, and the needle positions on the first needle bed corresponding to the tucks do not form loops. Subsequently, knit the back side with the second yarn on the second needle bed to obtain 1 row of second coils, thereby completing the first complete row of knitting in area A;

[0010] (3). Use the first yarn to knit the back side on the second needle bed in a cyclic array with 1 loop spaced by 1 empty needle to obtain 2 rows of third coils. For the third coils in one row, perform tuck knitting on 1 needle position of the first needle bed at an interval of 1+X needles. Subsequently, knit the front side with the second yarn on the first needle bed to obtain 1 row of fourth coils, thereby completing the first complete row of knitting in area B;

[0011] (4). Set the second complete row according to the above first complete row knitting setting. Use "2 complete rows" * "1+N" or "1+X" needles as one cycle, and the horizontal columns of each cycle are connected to form jacquard, thus completing the pattern program;

[0012] (4). After inputting the pattern program into a flat knitting machine for knitting, perform wool fulling operation to obtain the product.

[0013] In the second aspect of the present invention, there is provided a jacquard fabric with a relief effect obtained by the above knitting method.

[0014] The jacquard fabric with a relief effect of the present invention includes raised areas and sunken areas of a double-layer structure. It is knitted by controlling the row height ratio of the front and back side coils in the raised areas and sunken areas, and making the raised areas and sunken areas knitted with 1 tuck stitch in each complete row to connect the front and back sides without separation. Then, through the fulling treatment of the wool yarn, the obtained jacquard fabric has more obvious and finely adjustable relief raised areas, and its tissue texture is rich and beautiful, far better than the conventional relief effect. Moreover, it solves the serration and looseness problems that occur at the pattern boundaries in the conventional method, realizing smooth and natural pattern boundaries. At the same time, it also meets the perfect color-blocking jacquard requirements for the relief effect jacquard fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosed content of the present invention more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in the present invention includes any and all combinations of one or more of the related listed items.

[0022] In some embodiments of the present invention, a knitting method of a jacquard fabric with a relief effect is disclosed. The jacquard fabric with a relief effect includes an A area and a B area. The A area is a front convex area and is composed of a double-layer structure; the B area is a front concave area and is also composed of a double-layer structure. A knitting device including a first needle bed and a second needle bed is used for knitting, which specifically includes the following steps:

[0023] (1) Obtain a first yarn and a second yarn;

[0024] (2) Knit the front side with the first yarn on the first needle bed to obtain 2 rows of first coils. Perform tuck knitting on 1 needle position of the second needle bed at an interval of 1+N needles for one row of the first coils, and the needle positions on the first needle bed corresponding to the tucks do not form loops; then knit the back side with the second yarn on the second needle bed to obtain 1 row of second coils, thereby completing the first complete row of knitting in the A area. At this time, it can be found that the row height ratio of the first coils (front side) to the second coils (back side) in the first complete row is about 2:1. Therefore, the front structure will bulge slightly, initially forming the condition for the front relief bulge;

[0025] (3) Use the first yarn to knit the wrong side on the second needle bed in a cyclic array with 1 loop spaced by 1 empty needle to obtain 2 rows of third loops (the actual effective loop height is 1 row). For the third loops in one of the rows, perform gathering knitting on 1 needle position of the first needle bed at an interval of 1 + N needles. Subsequently, knit the right side on the first needle bed with the second yarn to obtain 1 row of fourth loops, thereby completing the knitting of the first complete row in area B. At this time, it can be found that the row height ratio of the third loops (wrong side) to the fourth loops (right side) in this first complete row is approximately 1:1. Therefore, the front and back sides are relatively flat and the front side does not bulge.

[0026] (4) According to the above setting of knitting the first complete row, knit the second complete row. Fill the A area and B area in a cycle of "2 complete rows" * "(1 + N)" or "(1 + X)" needles according to the above first and second complete rows. The first loop (right side) and the third loop (wrong side) are both knitted with the first yarn, and the second loop (wrong side) and the fourth loop (right side) are both knitted with the second yarn. The horizontal columns are connected in each cycle to form jacquard, and the pattern program is completed.

[0027] (4) After inputting the pattern program into the computerized flat knitting machine for knitting, send the semi-finished product to water treatment for conventional wool felting operation. Since the 1-needle gathering connects the front and back sides, the wool tissue on the wrong side felts, and the non-wool tissue on the right side is pulled and shrinks and aggregates. A more obvious bulge is formed in area A, and a strong broken pleat texture is presented, obtaining a fabric with a relief effect.

[0028] In some embodiments, in step (4), when knitting the second complete row, the gathering in the above-mentioned A area and B area is knitted in a staggered arrangement, that is, the gathering needle positions are staggered from the first complete row.

[0029] In some embodiments, the first yarn is a non-wool yarn and the second yarn is a wool yarn.

[0030] In some embodiments, the first yarn is thicker than the second yarn, which is beneficial to enhancing the relief convex effect.

[0031] In some embodiments, the first yarn and the second yarn are of the same color or different colors.

[0032] In some embodiments, the tissue tightness of the first yarn and the second yarn is different. By adjusting the tissue tightness of the first yarn and the second yarn in the computerized flat knitting machine (that is, adjusting the tightness of the first loop, the second loop, the third loop, and the fourth loop), the first yarn tissue is relatively loose and the second yarn tissue is relatively tight, which is beneficial to enhancing the relief convex effect.

[0033] In some embodiments, N is an integer from 1 to 6, and preferably N is 3.

[0034] In some of these embodiments, X is an integer from 1 to 6, preferably X is 3.

[0035] The jacquard fabric with a relief effect of the present invention includes a raised area formed by a double-layer structure and a recessed area formed by a double-layer structure. When weaving, in a complete row, the front side of the raised area is a group of non-wool yarn structures, and the back side is preferably a group of 100% wool yarn structures. The set knitting row height ratio of the front and back coils is about 2:1. Therefore, the non-wool yarn structure on the front side will bulge slightly, initially forming the conditions for the front relief bulge, and knitting 1 stitch of gather stitch at an interval of 1+N needles in each complete row to associate and not separate the front and back sides. When felting the wool structure subsequently, the wool structure on the back side will further shrink, making the coil row height ratio of the front and back sides indirectly become larger. Therefore, the non-wool yarn structure on the front side forms a more obvious bulge and presents a strong broken pleat texture, strengthening the relief effect; in a complete row, the front side of the recessed area is a group of 100% wool yarn structures, and the back side is a group of non-wool yarn structures. The set knitting row height ratio of the front and back coils is about 1:1 (the raised area and the recessed area naturally form a height difference, enabling the fabric to initially have the conditions for forming a relief effect). Therefore, the front and back sides relatively maintain a flat front surface and will not bulge, and knitting 1 stitch of gather stitch at an interval of 1+N needles in each complete row to associate and not separate the front and back sides. When felting subsequently, the front wool structure will further shrink and synergistically affect the front bulge of the raised area. During the weaving process, the coil row height ratio of the front and back sides of area A can be indirectly changed by appropriately adjusting the thickness of the first and second yarns or the tightness of the first, second, third, and fourth coils or the subsequent felting strength, so as to further adjust the final relief bulge effect.

[0036] In addition, since the raised area and the recessed area of the jacquard fabric with a relief effect of the present invention are both double-layer structures, there is no situation where the coils at the arc boundary increase or decrease in a stepped manner and bend when converting between a conventional single-layer structure and a double-layer structure, forming serrations. The graphic boundary of the relief area will not become loose and becomes smooth and natural. Also, different-color yarns can be hidden through the double-layer structure of the recessed area, meeting the requirements of perfect color-block jacquard.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1 Jacquard Fabric with a Relief Effect and Its Weaving Method

[0039] The weaving method of the jacquard fabric with a relief effect provided in this example includes the following steps:

[0040] 1. Select the target pattern

[0041] Respectively include area A and area B, with a size of 200 pix * 300 pix (such as Figure 1 )

[0042] 2. Edit the pattern program

[0043] In this embodiment, the first needle bed is the front needle bed and the second needle bed is the rear needle bed.

[0044] Area A is a positive convex area composed of double-layer tissues. Knit the front side with the first yarn on the front needle bed to obtain 2 rows of first coils. Among these 2 rows, in the first row, intarsia knitting is performed on 1 needle position of the rear needle bed at an interval of 1 + 3 (the corresponding needle position on the front needle bed does not form a loop). Subsequently, knit the reverse side with the second yarn on the rear needle bed to obtain 1 row of second coils. The above completes the first complete row knitting of area A. One pixel row in the pattern corresponds to one complete row ( Figure 2 ). At this time, it can be found that the row height ratio of the first coil (front side) to the second coil (reverse side) in this first complete row is approximately 2:1. Therefore, the front tissue will bulge slightly, initially forming the condition for a positive relief bulge.

[0045] Area B is a positive concave area, also composed of double-layer tissues. Use the first yarn to knit the reverse side on the rear needle bed with a cyclic array of 1 coil spaced 1 empty needle to obtain 2 rows of third coils (the actual effective coil height is 1 row). Among these 2 rows, in the first row, intarsia knitting is performed on 1 needle position of the front needle bed at an interval of 1 + 3. Subsequently, knit the front side with the second yarn on the front needle bed to obtain 1 row of fourth coils. The above completes the first complete row knitting of area B. One pixel row in the pattern corresponds to one complete row ( Figure 2 ). At this time, it can be found that the row height ratio of the third coil (reverse side) to the fourth coil (front side) in this first complete row is approximately 1:1. Therefore, the front and reverse sides remain flat relative to each other, and the front side does not bulge.

[0046] According to the above first complete row knitting setting, when knitting the second complete row, the intarsia of the above area A and area B is knitted in a staggered arrangement, that is, the intarsia position is staggered from the first complete row (such as Figure 2 ). Fill area A and area B with the above first and second complete rows in a cycle range of "2 complete rows" * "(1 + 3) = 4" needles. The first coil (front side) and the third coil (reverse side) are both knitted with the first yarn, and the second coil (reverse side) and the fourth coil (front side) are both knitted with the second yarn. Each cycle's horizontal columns are connected to form two-color jacquard, complete the pattern program and input it into the computerized flat knitting machine.

[0047] 3. Select knitting materials

[0048] There are 2 pieces of the first yarn, which is 2 / 32 100% cotton (khaki), and 1 piece of the second yarn, which is 2 / 60 100% wool (white). This setting makes the first yarn thicker than the second yarn, which is beneficial to enhancing the relief bulge effect.

[0049] 4. In the computer flat knitting machine, the tightness of the first yarn and the second yarn is adjusted. The first yarn is loose and the second yarn is tight, which is beneficial to enhance the embossed effect. A computer flat knitting machine (STOLL brand CMS530-7.2 model) is used to weave a semi-finished fabric with embossed effect.

[0050] 5. Send the semi-finished product to water treatment for conventional wool shrinking operation, with medium shrinking intensity (the operator performs conventional operation based on experience) to obtain a jacquard fabric with relief effect, such as Figure 3 and Figure 4 As shown. Figure 3 and Figure 4 It can be seen that the jacquard fabric woven in this embodiment presents a strong pleated texture. This is because the 1-needle tuck links the front and back sides, the wool tissue on the back side is shrunk, and the non-wool tissue on the front side is pulled and shrunk and gathered, forming a more obvious bulge in the A area. The texture is rich and beautiful, far better than the conventional relief effect, and the pattern boundary is smooth and natural. The double-layer tissue in the concave area hides the different-colored yarns, achieving the perfect contrast jacquard requirement of the relief effect jacquard fabric.

[0051] Example 2 Jacquard fabric with relief effect and weaving method thereof

[0052] The method for weaving a jacquard fabric with a relief effect provided in this embodiment comprises the following steps:

[0053] 1. Select the target pattern

[0054] Same as Example 1.

[0055] 2. Edit pattern program

[0056] Same as Example 1.

[0057] 3. Choose weaving materials

[0058] The first yarn is 2 / 32 100% cotton (white) 2 pieces, and the second yarn is 1 2 / 60 100% wool (white) 1 piece. This setting makes the first yarn thicker than the second yarn, which is beneficial to enhance the embossing effect.

[0059] 4. Use a computerized flat knitting machine (STOLL brand CMS530-7.2 model) to weave a semi-finished product of embossed fabric.

[0060] 5. Send the semi-finished product to water treatment for conventional wool shrinking operation to obtain jacquard fabric with relief effect.

[0061] The jacquard fabric woven in this embodiment presents a strong pleated texture, and the texture is rich and beautiful, far better than the conventional relief effect, and the pattern boundary is smooth and natural.

[0062] Example 3 Jacquard Fabric with Relief Effect and Its Weaving Method

[0063] The weaving method of the jacquard fabric with relief effect provided in this example includes the following steps:

[0064] 1. Select the target pattern

[0065] Same as Example 1.

[0066] 2. Edit the pattern program

[0067] Same as Example 1.

[0068] 3. Select the weaving materials

[0069] There are 2 pieces of the first yarn which is 2 / 32 100% cotton (khaki), and 2 pieces of the second yarn which is 2 / 32 100% wool (white).

[0070] This step is the same as Example 1.

[0071] 5. Send the semi-finished product to water treatment for conventional wool felting operation to obtain the jacquard fabric with relief effect.

[0072] The jacquard fabric woven in this example presents a strong crushed pleat texture. The tissue texture is rich and beautiful, far better than the conventional relief effect. And the pattern boundary is smooth and natural. By hiding the different-color yarns in the double-layer tissue of the concave area, the perfect color-blocking jacquard requirement of the relief effect jacquard fabric is achieved.

[0073] Comparative Example Conventional Weaving Method of Jacquard Fabric with Relief Effect

[0074] The jacquard fabric with relief effect provided in this comparative example adopts the conventional weaving method, including the following steps:

[0075] 1. Select the target pattern

[0076] It respectively includes area A and area B, with a size of 200 pix * 300 pix (such as Figure 1 ).

[0077] 2. Edit the pattern program

[0078] Area A is the front convex area, composed of double-layer tissue (sesame bottom), and area B is single-layer tissue (float line on one side). Input the pattern program into the computerized flat knitting machine.

[0079] Sesame bottom: It is fully knitted by the front and rear needle beds in a jacquard interleaving manner to obtain a double-layer structure tissue (the front and back sides of the tissue are connected).

[0080] Float line on one side: It is a single-layer structure tissue obtained by 1*1 empty needle interleaving knitting by the front needle bed or the rear needle bed.

[0081] 3. Select the weaving material

[0082] There are 2 pieces of the first yarn which is 2 / 32 100% cotton (khaki), and 2 pieces of the second yarn which is 2 / 32 100% cotton (white).

[0083] The finished fabric with a relief effect woven using this comparative example is as Figure 5 shown. It can be found from the finished product effect that for the relief fabric woven by the conventional weaving method, the raised surface effect is flat and monotonous, lacking texture, with a small degree of convexity, a weak relief effect, a fixed relief effect, no effective fine-tuning method, and a strong sense of serration at the graphic boundary of the relief area, being relatively loose and of low quality. Moreover, since the B area is a single-layer structure, when using cross-color jacquard, the different-color yarns in the B area are exposed on the surface to form color mixing, and a perfect cross-color jacquard effect, that is, relief with different colors, cannot be achieved.

[0084] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0085] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
