Description

Technical Field

[0001] This invention relates to the field of textile technology, and more specifically, to a curtain fabric and its weaving process. Background Technology

[0002] To achieve light-blocking properties, existing curtain fabrics often employ coatings or brushing processes. However, coatings release harmful substances that can be detrimental to the environment and human health. Brushing, on the other hand, loosens the fiber cohesion, making the fabric surface prone to lint and shedding during pulling and friction. This not only easily attracts dust and breeds bacteria, but also poses a safety hazard to the respiratory tract and skin of infants if inhaled. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a curtain fabric and its weaving process. Through the V-shaped fitting structure of the second region and the wave-shaped fitting structure of the third region, a natural convergence effect is formed. In a natural state, adjacent second raised areas spontaneously cover the second base fabric area, and adjacent third raised areas completely cover the third base fabric area. The second and third raised areas are respectively connected to the first raised area, causing the first raised area to twist and cover the first base fabric area. Therefore, while reducing the fabric weight, the light-blocking properties of the fabric are maintained. The second raised areas are arranged in a V-shape, causing the coils in the second raised areas to form a mutually hugging state, preventing fiber pull-out. The third raised area has a wave-shaped structure, causing the coils to form a continuous bending and hugging along the fabric width direction, avoiding fiber friction and shedding. The self-locking structure prevents fiber shedding. The second and third regions drive the coils in the first region to tighten synchronously, and the staggered arrangement further tightens the coils in the first region itself, reducing fiber floating and shedding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a curtain fabric, comprising a first region, a second region, and a third region, wherein the first region, the second region, and the third region are arranged along the length of the fabric in the following order: one first region, one second region, one first region, and one third region.

[0005] The first region includes a first raised area and a first base fabric area, which are arranged alternately and cyclically along the fabric width direction;

[0006] The second region includes a second raised area and a second base fabric area. The second raised area is in the shape of an inverted V. The second base fabric area is in the shape of a V and an inverted V. The inverted V-shaped second base fabric area is located inside the second raised area, and the V-shaped second base fabric area is located between the two second raised areas.

[0007] The third region includes a third raised region and a third base fabric region. The third raised region is in the shape of an inverted V. The third base fabric region is in the shape of a V and an inverted V. The inverted V-shaped third base fabric region is located inside the third raised region. The V-shaped third base fabric region is located between the two third raised regions. The third raised region and the third base fabric region are in a wave-like fit.

[0008] Furthermore, along the length of the fabric, the first raised area of ​​one of the two adjacent first regions is opposite to the first base fabric area of ​​the other first region, and the first base fabric area of ​​one of the first regions is opposite to the first raised area of ​​the other first region.

[0009] Furthermore, along the length of the fabric, the tip of the second protrusion is connected to the first protrusion mentioned above, and the lower ends of the second protrusion are connected to the following two first protrusions respectively, with the connection position of each lower end of the second protrusion located at half the width of the first protrusion.

[0010] Furthermore, along the length of the fabric, the upper ends of the two third protrusion areas are connected to the first protrusion areas listed above, and the lower ends of the third protrusion areas are connected to the two first protrusion areas listed below, respectively. The connection position of the lower end of each third protrusion area is located at half the width of the first protrusion area.

[0011] Furthermore, the height difference between the first protruding area and the first base fabric area is H1, the height difference between the second protruding area and the second base fabric area is H2, and the height difference between the third protruding area and the third base fabric area is H3, and H1=H2=H3.

[0012] This invention also discloses a weaving process for curtain fabric, including the following steps:

[0013] S1: Basic preparation steps: The fabric is knitted using a double-sided weft knitting machine, and the stitch length, cylinder diameter, density, and width are set.

[0014] S2: Needle arrangement and yarn preparation;

[0015] S3: Weaving;

[0016] S4: Unloading and post-processing.

[0017] Furthermore, the stitch length is 3.3cm, the density is 24 stitches / inch, the tube diameter is 34 inches, the width is 169cm, and the fabric weight is 318g / m². 2 .

[0018] Furthermore, the upper needle arrangement is 12131212, and the lower needle arrangement is 13312442. The fabric uses 50D / 72F polyester filament as the face yarn and 75D / 36F semi-dull polyester filament as the ground yarn.

[0019] Furthermore, the fabric is woven with 32 rows of coils, with 8 rows of coils forming the first region, 8 rows of coils forming the second region, and 8 rows of coils forming the third region.

[0020] Furthermore, in the natural state of the fabric, along the fabric width direction, two adjacent second protrusion areas naturally move closer together and cover the second base fabric area, and two adjacent third protrusion areas naturally move closer together and cover the third base fabric area. In the stretched state of the fabric, the first protrusion area, the second protrusion area and the third protrusion area form a mesh, and the first base fabric area, the second base fabric area and the third base fabric area are located inside the mesh.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The second raised areas in the second region are arranged in a V-shape, and the third raised areas in the third region are arranged in a wave-like shape. The V-shaped tips of the second and third raised areas are integrally connected to the first raised area. In a natural hanging state, the inward stress of the V-shaped structure of the second raised area causes the two adjacent second raised areas to naturally move closer together, and the contraction stress of the wave-like structure of the third raised area causes the two third raised areas to naturally move closer together, thus naturally covering the second and third base fabric areas respectively. The second and third raised areas are transmitted to the first raised area through the connection endpoints, causing the first raised area to undergo slight twisting deformation at the connection with the second and third raised areas, thus naturally covering the first base fabric area and forming physical shading.

[0023] 2. The second raised area and the second base fabric area are arranged in a V-shape, so that the loops of the V-shaped second raised area form a naturally nested and cohesive state through tuck weaving, increasing the cohesion between the loops and preventing the fibers from being pulled out by external force. The third raised area and the third base fabric area have a wavy structure, so that the loops form a continuous bending cohesion, thereby preventing fiber friction and shedding. The first raised area connects with the second and third raised areas to form a spontaneous twist, and the first base fabric area connects with the second and third base fabric areas. Furthermore, the first area is staggered along the length of the fabric, so that the loops in the first area not only pass through... The second and third regions form a twist, while the coils of two adjacent first regions along the fabric length are staggered. This causes the coils of the first region to tighten synchronously, and the staggered arrangement further tightens the coils of the first region itself. Thus, the weaving structure self-locks the fibers of the first, second, and third regions, preventing fiber shedding and reducing fiber lint and pilling. At the same time, the first region also forms a longitudinal constraint on the structure of the second and third regions, preventing the V-shaped structure of the second region and the wavy structure of the third region from loosening and deforming after long-term use.

[0024] 3. The height difference H1 between the first raised area and the first base fabric area is equal to the height difference H2 between the second raised area and the second base fabric area, and equal to the height difference H3 between the third raised area and the third base fabric area. This ensures that when the fabric is in its natural state, the second and third raised areas will not form step-like gaps due to the height difference, resulting in local light leakage. Furthermore, through the equal height design, the second and third raised areas form a stable stress transfer to the first raised area, thereby causing the first raised area to form a stable micro-twist. At the same time, it ensures that the coils between the second and third raised areas are subjected to uniform force, preventing coil slack and deformation. Attached Figure Description

[0034] like Figures 1 to 7 As shown, this embodiment discloses a curtain fabric. The fabric is woven using a double-sided weft knitting machine, with a stitch length of 3.3cm, a density of 24 stitches / inch, a tube diameter of 34 inches, a width of 169cm, and a fabric weight of 318g / m². 2 .

In the lower needle cylinder, knit the 2nd and 4th needles into a loop, and do not knit the 1st and 3rd needles.

[0039] In the first to eighth loop rows, the upper needle plate needles are arranged in a 1213 pattern and the lower needle cylinder needles are arranged in a 1331 pattern to form the first raised area 11. In the second loop rows, the upper needle plate needles are arranged in a 1212 pattern and the lower needle cylinder needles are arranged in a 2442 pattern to form the first base fabric area 12. In the seventh to twenty-fourth loop rows, the upper needle plate needles are arranged in a 1213 pattern and the lower needle cylinder needles are arranged in a 1331 pattern to form the first base fabric area 12. In the third loop rows, the upper needle plate needles are arranged in a 1212 pattern and the lower needle cylinder needles are arranged in a 2442 pattern to form the first raised area 11. Therefore, the first region 1 includes the first raised area 11 and the first base fabric area 12, and the first raised area 11 and the first base fabric area 12 are arranged alternately and cyclically along the fabric width direction.

[0040] Because the first raised area 11 in the first-to-8 loop rows is located at the upper needle plate needle arrangement at 1213 and the lower needle cylinder needle arrangement at 1331, and the first base fabric area 12 is located at the upper needle plate needle arrangement at 1212 and the lower needle cylinder needle arrangement at 2442, while the first raised area 11 in the 17-to-24 loop rows is located at the upper needle plate needle arrangement at 1212 and the lower needle cylinder needle arrangement at 2442, and the first base fabric area 12 is located at the upper needle plate needle arrangement at 1213 and the lower needle cylinder needle arrangement at 1331, therefore, along the fabric length direction, the first raised area 11 of one of the two adjacent first regions 1 is opposite to the first base fabric area 12 of the other first region 1, and the first base fabric area 12 of one of the first regions 1 is opposite to the first raised area 11 of the other first region 1.

[0041] In the second area 2 formed by knitting rows 9-16, in rows 9, 11, 13, and 15, the first, second, and third needles on the upper needle plate are not knitted, and the first, second, third, and fourth needles on the lower needle cylinder are not knitted. In row 10, the first, second, and third needles on the upper needle plate are knitted into loops, the third needle on the lower needle cylinder knits a rounded loop, and the first, second, and fourth needles are not knitted. In row 12, the first, second, and third needles on the upper needle plate are knitted into loops, and the first, second, and fourth needles on the lower needle cylinder are not knitted. Knitting the 2nd and 3rd needles into loops, knitting the 1st needle in the lower cylinder into a tucked loop, and not knitting the 2nd, 3rd, and 4th needles. In the 14th row of loops, knitting the 1st, 2nd, and 3rd needles in the upper needle plate into loops, and knitting the 4th needle in the lower cylinder into a tucked loop, and not knitting the 1st, 2nd, and 3rd needles. In the 16th row of loops, knitting the 1st, 2nd, and 3rd needles in the upper needle plate into loops, and knitting the 2nd needle in the lower cylinder into a tucked loop, and not knitting the 1st, 3rd, and 4th needles.

[0042] In the 9th-16th loop rows, the upper needle arrangement of the upper needle plate is 1213 and the lower needle arrangement is 1331 in the 9th-12th loop rows, and the upper needle arrangement of the upper needle plate is 1212 and the lower needle arrangement is 2442 in the 13th-16th loop rows, forming the second raised area 21. This is because the 3rd needle of the lower needle cylinder is knitting a loop in the 10th loop row, while the 3rd needle of the lower needle cylinder is knitting a loop in the 9th loop row, the 1st needle of the lower needle cylinder is knitting a loop in the 12th loop row, and the 1st needle of the lower needle cylinder is knitting a loop in the 11th loop row. The second raised area 21 is formed in the 9th-16th loop rows. In the 13th to 16th loop rows, the 4th needle of the lower cylinder knits a tuck loop in the 14th loop row, while the 4th needle of the lower cylinder knits a loop in the 13th loop row. The 2nd needle of the lower cylinder knits a tuck loop in the 16th loop row, and the 2nd needle of the lower cylinder knits a loop in the 15th loop row. However, in the 10th, 12th, 14th, and 16th loop rows, only two needles of the lower cylinder knit a tuck loop, while the rest do not knit. In the 9th, 11th, 13th, and 15th loop rows, all needles of the lower cylinder knit. Therefore, the tuck loop pulls the yarn, causing the second raised area 21 to form an inverted V shape.

[0043] In the knitting cycle, because the needle arrangement of the upper needle plate (1212) and the lower needle cylinder (1331) in the 9th-12th loop rows are located inside the knitting of the second raised area 21 during the knitting process, while the needle arrangement of the upper needle plate (1213) and the lower needle cylinder (1331) in the 13th-16th loop rows are located outside the knitting of the second raised area 21 during the knitting process, the knitting of the upper needle plate (1212) and the lower needle cylinder (1331) in the 9th-12th loop rows forms a knitting pattern similar to that of the 9th-12th loop rows. The second base fabric area 22, which is the same as the second raised area 21, is an inverted V-shaped second base fabric area. The needles of the upper needle plate in the 13th-16th row of the loop are arranged as 1213 and the needles of the lower needle cylinder are arranged as 1331 to form a V-shaped second base fabric area 22. Therefore, the second region 2 includes the second raised area 21 and the second base fabric area 22. The second base fabric area 22 is V-shaped and inverted V-shaped. The inverted V-shaped second base fabric area 22 is located inside the second raised area 21, and the V-shaped second base fabric area 22 is located between the two second raised areas 21.

[0044] Because the second raised area 21 is adjacent to the tuck stitch position in the 10th and 14th loop rows, but separated by two needles in the tuck stitch positions in the 12th and 16th loop rows, and the needle position of the second raised area 21 in the 9th-12th loop rows is at the upper needle plate needle arrangement of 1213 and the lower needle cylinder needle arrangement of 1331, while the needle position of the first raised area 11 in the 1st-8th loop rows is also at the upper needle plate needle arrangement of 1213 and the lower needle cylinder needle arrangement of 1331, and the second raised area 21 in the 13th-16th loop rows... The knitting needle positions are at the upper needle plate needle arrangement of 1212 and the lower needle cylinder needle arrangement of 2442. The first protrusion area 11 is also at the knitting needle positions of the 17th to 24th loop rows at the upper needle plate needle arrangement of 1212 and the lower needle cylinder needle arrangement of 2442. Therefore, along the length of the fabric, the tip of the second protrusion area 21 is connected to the first protrusion area 11 above, and the lower ends of the second protrusion area 21 are connected to the following two first protrusion areas 11 respectively. The connection position of each lower end of the second protrusion area 21 is located at half the width of the first protrusion area 11.

[0045] In the third area 3 formed by knitting rows 25-32, in row 25, the 3rd needle on the upper needle plate knits a round, while the 1st and 2nd needles do not knit. The 2nd needle on the lower needle cylinder knits a round, while the 1st, 3rd, and 4th needles do not knit. In row 26, the 3rd needle on the upper needle plate knits a round, while the 1st and 2nd needles do not knit. The 4th needle on the lower needle cylinder knits a round, while the 1st, 2nd, and 3rd needles do not knit. In rows 27 and 31, the 1st, 2nd, and 3rd needles on the upper needle plate do not knit, while the 1st, 2nd, and 3rd needles on the lower needle cylinder... The 4th needle is knitted into a loop. In the 28th and 32nd loop rows, the 3rd needle on the upper needle plate is knitted into a loop, and the 1st and 2nd needles are not knitted. The 1st, 2nd, 3rd, and 4th needles on the lower needle cylinder are not knitted. In the 29th loop row, the 3rd needle on the upper needle plate knits a rounded loop, and the 1st and 2nd needles are not knitted. The 3rd needle on the lower needle cylinder is knitted into a loop, and the 1st, 2nd, and 4th needles are not knitted. In the 30th loop row, the 3rd needle on the upper needle plate knits a rounded loop, and the 1st and 2nd needles are not knitted. The 1st needle on the lower needle cylinder is knitted into a loop, and the 2nd, 3rd, and 4th needles are not knitted.

[0046] In the 25th-32nd loop rows, the upper needle plate needles of the 25th-28th loop rows are arranged with 1212 and the lower needle cylinder needles are arranged with 2442, and the upper needle plate needles of the 29th-32nd loop rows are arranged with 1213 and the lower needle cylinder needles are arranged with 1331 to form the third raised area 31. The upper needle plate needles of the 25th-28th loop rows are arranged with 1213 and the lower needle cylinder needles are arranged with 1331, and the upper needle plate needles of the 29th-32nd loop rows are arranged with 1212 and the lower needle cylinder needles are arranged with 2442 to form the third base fabric area 32. Therefore, the third area 3 includes the third raised area 31 and the third base fabric area 32.

[0047] In the 25th, 26th, 28th, 29th, 30th, and 31st loop rows, the upper needle plate is knitted by the 3rd needle, while the 1st and 2nd needles are not knitted. In the 25th, 26th, 29th, and 30th loop rows, the 3rd needle of the upper needle plate is knitted in a tucked loop, while in the 28th and 32nd loop rows, the 3rd needle of the upper needle plate is knitted in a loop. This makes the third raised area 31 wavy. The knitting of the third base fabric area 32 is adjacent to and symmetrical with that of the third raised area 31. Therefore, the third raised area 31 and the third base fabric area 32 fit together in a wavy shape.

[0048] The third raised area 31 is positioned at the intersection of needle arrangement 1212 on the upper needle plate and needle arrangement 2442 on the lower needle cylinder in the 25th and 26th loop rows. However, in the 25th loop row, the second needle of the lower needle cylinder knits a loop, while the other needles do not. In the 26th loop row, the fourth needle of the lower needle cylinder knits a loop, while the other needles do not. In the 29th and 30th loop rows, the third raised area 31 is positioned at the intersection of needle arrangement 1213 on the upper needle plate and needle arrangement 1331 on the lower needle cylinder. However, in the 29th loop row, the third needle of the lower needle cylinder knits a loop, while the other needles do not. In the 30th loop row, the first needle of the lower needle cylinder knits a loop, while the other needles do not. This is because the positions of the third raised area 31 are adjacent in the 26th and 29th loop rows, while in the 25th and 30th loop rows, the knitting positions of the third raised area 31 are... Two needles are spaced between the positions, and the 27th, 28th, 31st, and 32nd loop rows do not affect the knitting of the 25th, 26th, 29th, and 30th loop rows, thus making the third raised area 31 an inverted V shape. In the weave cycle, the third base fabric area 32 formed by the upper needle arrangement 1212 and the lower needle arrangement 2442 in the 29th-32nd loop rows is located inside the needle knitting position of the third raised area 31. The third base fabric area 32 formed by the upper needle arrangement 1213 and the lower needle arrangement 1331 in the 25th-28th loop rows is located outside the needle knitting position of the third raised area 31. Therefore, the third base fabric area 32 is V-shaped and inverted V-shaped. The inverted V-shaped third base fabric area 32 is located inside the third raised area 31, and the V-shaped third base fabric area 32 is located between the two third raised areas 31.

[0049] The needle positions for the third raised area 31 formed by the horizontal knitting of the 25th to 28th coils are the same as the needle positions for the first raised area 11 formed by the horizontal knitting of the 17th to 24th coils. The needle positions for the third raised area 31 formed by the horizontal knitting of the 29th to 32nd coils are the same as the needle positions for the first raised area 11 formed by the horizontal knitting of the 1st to 8th coils in the next weave cycle. Therefore, along the length of the fabric, the upper ends of the two third raised areas 31 are connected to the first raised area 11 above, and the lower ends of the third raised areas 31 are connected to the two first raised areas 11 below, respectively. The connection position of each lower end of the third raised area 31 is located at half the width of the first raised area 11.

[0050] Therefore, the second raised area 21 and the second base fabric area 22 are arranged in a V-shape, and the third raised area 31 and the third base fabric area 32 are arranged in a wave-like shape. Both the second raised area 21 and the third raised area 31 are V-shaped, and their pointed ends are connected to the first raised area 11. This causes the V-shaped structure of the second raised area 21 to generate inward stress in the fabric's natural state, causing the loops of adjacent second raised areas 21 to naturally converge along the fabric width, thus naturally covering the loops of the second base fabric area 22. Similarly, the shrinkage stress of the wave-like structure of the third raised area 31 also converges along the fabric width, causing the loops of adjacent third raised areas 31 to naturally converge, thus naturally covering the loops of the third base fabric area 32. The second raised area 21... The tip of the third protruding area 31 is connected to the first protruding area 11, and the inward stress of the second protruding area 21 and the shrinkage stress of the third protruding area 31 are both applied to the first protruding area 11 through the yarn at the same time. This causes the first protruding area 11 to twist and deform through the connection, and the coils of the first protruding area 11 also come together, thus naturally covering the coils of the first base fabric area 12, thereby forming physical light blocking. When the fabric is stretched, the first protruding area 11, the second protruding area 21 and the third protruding area 31 are connected to form a mesh, and the first base fabric area 12, the second base fabric area 22 and the third base fabric area 32 are connected inside the mesh. This not only increases the breathability of the fabric, but also reduces the accumulation of dust mites inside the fabric, thereby reducing the breeding of mites.

[0051] The second raised area 21 and the second base fabric area 22 are arranged in a V-shape. When the second raised area 21 is located in the 10th, 12th, 14th, and 16th coil rows, it is tucked together. This tucking allows the coils of the second raised area 21 to form a naturally interlocking state, thereby increasing the cohesive force between the coils, increasing the light-blocking property of the fabric, and preventing the fibers from being pulled out by external forces. The third raised area 31 and the third base fabric area 32 have a wavy structure. Similarly, through tucking, the coils of the third raised area 31 form a continuous curved cohesive structure, thereby preventing fiber friction and shedding. Furthermore, the second area 2 is V-shaped, and the third area 3 is wavy, and they are arranged alternately between the first area 1 and the second area 22, which can more comprehensively adapt to external forces and prevent the coils from breaking due to a single structure. The first raised area 11 and the second raised area 21, the 12th, 14th, and 16th coil rows are tucked together. The three raised areas 31 are connected to form a spontaneous torsional deformation. The first base fabric area 12 is connected to the second base fabric area 22 and the third base fabric area 32. The first area 1 is staggered along the length of the fabric, so that the coils of the first area 1 not only twist through the second area 2 and the third area 3, but also the coils of two adjacent first areas 1 are staggered along the length of the fabric. This causes the coils of the first area 1 to be driven by the second area 2 and the third area 3 to tighten synchronously. The weaving structure makes the coils self-locking, thereby preventing fiber shedding and reducing the phenomenon of floating and shedding. At the same time, the staggered arrangement of the first area 1 forms a longitudinal constraint on the structure of the second area 2 and the third area 3, so that the V-shaped structure of the second area 2 and the wavy structure of the third area 3 will loosen and deform after long-term use.

[0052] Because the first raised area 11 is knitted by both upper needle plate needles and lower needle cylinder needles in the 1st to 8th loop rows, while the first base fabric area 12 is knitted only by upper needle plate needles and lower needle cylinder needles in the 4th and 6th loop rows, and only by upper needle plate needles in the 1st, 2nd, 3rd, 5th, 7th, and 8th loop rows, with no knitting by lower needle cylinder needles, the height difference between the first raised area 11 and the first base fabric area 12 is H1. The second raised area 21 is knitted by both upper needle plate needles and lower needle cylinder needles in the 10th, 12th, 14th, and 16th loop rows, while the second base fabric area 22 is knitted only by upper needle plate needles or lower needle cylinder needles in the 9th to 16th loop rows, the height difference between the second raised area 21 and the second base fabric area 22 is H2. The third raised area 31 is knitted by upper needle plate needles or lower needle cylinder needles in the 25th, 27th, 26th, and 29th loop rows. In the 30th and 31st loop rows, the lower needle cylinder is used for knitting, while in the 25th, 26th, 28th, 29th, 30th and 31st loop rows, the upper needle plate is used for knitting. The lower needle cylinder knits the front loops, and the upper needle plate knits the back loops. Therefore, the height difference between the third raised area 31 and the third base fabric area 32 is H3, and H1=H2=H3. This ensures that in the natural state of the fabric, the second raised area 21 and the third raised area 31 will not form a stepped gap due to the height difference, resulting in local light leakage. Furthermore, the equal height design allows the second raised area 21 and the third raised area 31 to form a stable stress transfer to the first raised area 11. This allows the loops of the second raised area 21, the third raised area 31 and the first raised area 11 to be brought closer together through stress, thus ensuring the physical light-blocking properties of the fabric.
