Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a weaving method of a back-hanging fabric and the fabric. Background Art

[0002] The weaving of existing elastic fabrics usually uses at least two yarns, one of which is the back yarn, which mainly plays an elastic role, making the fabric elastic and not showing on the surface of the fabric. It is usually also used as the starting yarn to weave anti-slip loops to prevent the starting part of the fabric from breaking; the remaining yarns are mainly used as veils and displayed on the surface of the fabric.

[0003] See also Figure 1 and Figure 2 As shown, the existing back-hanging fabric is mainly woven by alternating back-hanging yarn and face yarn, that is, the existing circular knitting machine weaves elastic fabric in a way that the needle cylinder hooks the face yarn and moves full-position needles in both forward and reverse rotations (two face yarn weaving rows), and the rear needle cylinder hooks the back-hanging yarn and moves one-half position in both forward and reverse rotations (one back-hanging yarn weaving row). Since a back-hanging yarn weaving row formed by the forward and reverse back-hanging yarn will only appear behind one face yarn weaving row, there is no back-hanging yarn weaving row behind the other face yarn weaving row, that is, the back-hanging yarn weaving rows in the woven fabric are spaced, resulting in sparse fabric.

[0004] See also Figure 3 As shown, in order to improve the back-hanging yarn weaving row with intervals, if the forward and reverse rotation of the face yarn is directly split, and a forward and reverse back-hanging yarn is inserted therein, although there is no interval in the back-hanging yarn weaving row in the fabric, the problem of sparse fabric is solved, but because the face yarn only executes forward rotation, the face yarn hooked by the needle of the needle cylinder is still at the end of the forward rotation. At this time, the position of the shuttle with the back-hanging yarn for weaving is different from the position of the face yarn. The circular knitting machine gives priority to the back-hanging yarn weaving demand that is currently being executed, and the needle cylinder rotates to the end of the forward rotation. The back-hanging yarn is first reversed and hooked, and then forwarded. At this time, the face yarn that executes the reverse hooking will cross with the back-hanging yarn that is hooked in the forward rotation, and there will be many flying lines in the cycle (see Figure 3 In the middle, the blue oblique line), the back yarn and the veil are prone to entanglement during the weaving process, and it is not conducive to hiding the back yarn. Summary of the invention

[0005] Therefore, it is necessary to provide a weaving method with back-hanging fabrics, which solves the problem of sparse absorption of existing elastic fabrics.

[0006] To achieve the above-mentioned purpose, the present invention provides a weaving method with a back-hanging fabric, wherein the fabric is woven by a circular knitting machine, and the back-hanging fabric includes at least one circulation unit, wherein the circulation unit first hooks the face yarn through a needle cylinder to weave in a forward rotation, and then hooks the back-hanging yarn through a needle cylinder to weave in a forward and reverse rotation in sequence; then hooks the face yarn through a needle cylinder to weave in a reverse rotation, and finally hooks the back-hanging yarn through a needle cylinder to weave in a forward and reverse rotation in sequence.

[0007] Furthermore, when the position of the needle cylinder is different from the face yarn weaving position or the back yarn weaving position, the needle cylinder rotates forward or reversely to produce an empty needle.

[0008] Furthermore, the circulation unit specifically includes the following weaving sequence:

[0009] The needle cylinder hooks the veil and rotates forward to weave;

[0010] The needle barrel reverses and moves the empty needle;

[0011] The needle cylinder hooks the back yarn and rotates forward to weave;

[0012] The needle cylinder hooks the back yarn and reverses to weave;

[0013] The syringe is rotating and the empty needle is removed;

[0014] The needle hooks the veil and reverses it to weave;

[0015] The needle cylinder hooks the back yarn and rotates forward to weave;

[0016] The needle cylinder hooks the back yarn and reverses to weave.

[0017] Furthermore, there are a plurality of the circulation units, and the plurality of the circulation units are tightly connected.

[0018] Furthermore, the needle cylinder hooks the yarn and rotates forward or reversely to move the full-position needle for weaving.

[0019] Furthermore, the needle cylinder hooks the back-hanging yarn and rotates forward and reversely to weave with a half-position needle.

[0020] Furthermore, the veil is TPU.

[0021] Furthermore, the back-hanging yarn is an elastic yarn.

[0022] Furthermore, the back-hanging yarn is a core-spun yarn.

[0023] A fabric with a back hanging is woven and formed by applying the weaving method of the fabric with a back hanging.

[0024] Different from the prior art, the above technical scheme splits the continuous weaving of the face veil in forward and reverse rotation in sequence, and connects the back yarn that is woven in forward and reverse rotation in sequence after each forward or reverse weaving of the face veil, so that each face veil weaving row has a back yarn weaving row formed by the forward and reverse back yarn, so that there is no gap in the back yarn weaving rows in the fabric, which solves the problem of sparse fabric; at the same time, the original weaving positions of the face veil and the back yarn are kept unchanged, avoiding the generation of many flying lines and even entanglement problems during the cyclic weaving process, effectively reducing the downtime of the circular knitting machine due to flying lines and entanglement, thereby improving production efficiency; at the same time, it helps to improve the quality of the fabric and ensure that the fabric has better strength and durability.

[0042] See also Figure 4-Figure 5 As shown, the present invention provides a weaving method of a back-hanging fabric, which is woven by a circular knitting machine; by splitting the continuous weaving of the face yarn 10 in forward and reverse rotation in sequence, the back-hanging yarn 20 woven in forward and reverse rotation in sequence is connected after each forward or reverse weaving of the face yarn 10, so that each face yarn weaving row has a back-hanging yarn weaving row formed by the forward and reverse back-hanging yarn 20, so that there is no gap in the back-hanging yarn weaving rows in the fabric, which solves the problem of sparse fabric; at the same time, the original weaving positions of the face yarn 10 and the back-hanging yarn 20 are kept unchanged, avoiding the generation of many flying lines and even entanglement during the cyclic weaving process, effectively reducing the downtime of the circular knitting machine due to flying lines and entanglement, thereby improving production efficiency; at the same time, it helps to improve the quality of the fabric and ensure that the fabric has better strength and durability.

[0043] The following is an embodiment of a weaving method of a back-hanging fabric of the present invention. The fabric is woven by a circular knitting machine, and the back-hanging fabric includes at least one circulation unit, wherein the circulation unit firstly hooks the face yarn 10 through a needle cylinder to rotate forward for weaving, then hooks the back-hanging yarn 20 through a needle cylinder to rotate forward and reverse in sequence for weaving; then hooks the face yarn 10 through a needle cylinder to reverse for weaving, and finally hooks the back-hanging yarn 20 through a needle cylinder to rotate forward and reverse in sequence for weaving.

[0044] The above-mentioned veil 10 refers to the yarn that is displayed on the surface of the fabric after being woven to form the fabric. The characteristics and quantity of the veil 10 are not limited. If there are multiple yarns, the multiple yarns can have different or the same characteristics, which can be selected according to needs. The diversity of fabric design can be achieved by changing yarns of different colors. The above-mentioned back yarn 20 refers to the yarn that is not displayed on the surface of the fabric after being woven to form the fabric. The characteristics and quantity of the back yarn 20 are not limited. If there are multiple yarns, the multiple yarns can have different or the same characteristics, which can be selected according to needs. Similarly, the veil 10 and the back yarn 20 can have different or the same characteristics, and the quantity can be the same or different. The above-mentioned characteristics refer to yarn color, material, elasticity, etc.

[0045] The above-mentioned forward rotation usually refers to that the needle cylinder of the circular knitting machine rotates in a predetermined direction (such as clockwise or counterclockwise), while the reverse rotation is the direction opposite to the forward rotation; if the forward rotation is clockwise, the reverse rotation is counterclockwise. The above-mentioned needle cylinder hooks the face veil 10 for forward rotation and weaving, which means that the needle cylinder hooks the face veil 10 and drives the face veil 10 to weave in the forward direction, so that the face veil 10 forms a coil structure, and is woven into a yarn row, which appears on the surface of the fabric; similarly, the above-mentioned needle cylinder hooks the face veil 10 for reverse weaving, which means that the needle cylinder hooks the face veil 10 and drives the face veil 10 to weave in the reverse direction, so that the face veil 10 forms a coil structure, and is woven into a yarn row; similarly, the above-mentioned needle cylinder hooks the back hanging yarn 20 and rotates forward and reverse in sequence for weaving, which means that the needle cylinder first hooks the back hanging yarn 20, drives the back hanging yarn 20 to weave in the forward direction first, so that the back hanging yarn 20 forms a coil structure, and then weaves in the reverse direction, so that the back hanging yarn 20 forms a coil structure, and rotates forward and reverse in sequence to weave into a back hanging yarn row, which does not appear on the surface of the fabric, that is, it does not appear on the surface of the fabric together with the face veil row.

[0046] In the weaving process of the above weaving method, after the needle cylinder hooks the face yarn 10 and rotates forward to complete weaving, the needle cylinder is at the end point of the forward rotation (also the starting point of the reverse rotation), and the next step requires the needle cylinder to hook the back yarn 20 and rotate forward. At this time, the needle cylinder needs to be at the starting point of the forward rotation (also the end point of the reverse rotation), and the position of the needle cylinder is different from the weaving position of the back yarn 20; or after the needle cylinder hooks the back yarn 20 and reverses to complete weaving, the needle cylinder is at the end point of the reverse rotation (also the starting point of the forward rotation), and the next step requires the needle cylinder to hook the face yarn 10 and reverse. At this time, the needle cylinder needs to be at the starting point of the reverse rotation (also the end point of the forward rotation), and the position of the needle cylinder is different from the weaving position of the face yarn 10; that is, there is a situation where the needle cylinder position is different from the weaving position of the face yarn 10 or the weaving position of the back yarn 20, which can be achieved by letting the needle rotate forward or reverse to produce an empty needle. The above-mentioned needle cylinder forward or reverse rotation and empty needle means that the needle cylinder does not hook the face yarn 10 or the back yarn 20 during the forward or reverse rotation, and rotates forward or reverses to return to the face yarn 10 weaving position or the back yarn 20 weaving position in an empty needle mode.

[0047] To further illustrate the present invention and help understand the present invention, the present invention provides a specific weaving sequence.

[0048] The number of needles usually determines the width of the back-hanging fabric. The following explanation takes 1-20 needles as an example of a knitting line, the forward start end (reverse end end) is the 1st needle, and the forward end end (reverse start end) is the 20th needle.

[0049] That is, the circulation unit specifically includes the following weaving sequence:

[0050] The needle cylinder hooks the yarn 10 and rotates forward to weave; (the needle cylinder hooks the yarn 10 and rotates forward from the 1st needle to the 20th needle, and finally the needle cylinder stops at the 20th needle)

[0051] The needle cylinder reverses and moves to an empty needle; (the needle cylinder reverses from the 20th needle to the 1st needle, and finally the needle cylinder stops at the position of the 1st needle)

[0052] The needle cylinder hooks the back-hanging yarn 20 and rotates forward to weave; (the needle cylinder hooks the back-hanging yarn 20 and rotates forward from the 1st needle to the 20th needle, and finally the needle cylinder stops at the 20th needle position)

[0053] The needle cylinder hooks the back hanging yarn 20 and reverses to weave; (the needle cylinder hooks the back hanging yarn 20 and reverses from the 20th needle to the 1st needle, and finally the needle cylinder stops at the position of the 1st needle)

[0054] The needle cylinder rotates forward and moves an empty needle; (the needle cylinder rotates forward from the 1st needle to the 20th needle, and finally the needle cylinder stops at the 20th needle position)

[0055] The needle cylinder hooks the yarn 10 and reverses to weave; (the needle cylinder hooks the yarn 10 and reverses to weave from the 20th needle to the 1st needle, and finally the needle cylinder stops at the position of the 1st needle)

[0056] The needle cylinder hooks the back-hanging yarn 20 and rotates forward to weave; (the needle cylinder hooks the back-hanging yarn 20 and rotates forward from the 1st needle to the 20th needle, and finally the needle cylinder stops at the 20th needle position)

[0057] The needle cylinder hooks the back yarn 20 and reverses to weave. (The needle cylinder hooks the back yarn 20 and reverses from the 20th needle to the 1st needle, and finally the needle cylinder stops at the position of the 1st needle)

[0058] The above forms a circulation unit. Usually, there are several circulation units in the fabric, that is, there are several circulation units, and the circulation units can be arranged in a linear arrangement, a circular arrangement, a matrix arrangement, etc. Each circulation unit can be kept at a certain interval or can be closely connected.

[0059] The needle cylinder hooks the veil 10 and rotates forward or reversely to weave with full-position needles. Each needle participates in weaving, so that each coil is connected to the adjacent coil to form a continuous coil structure, so that the veil 10 presents a high-density interlaced state in the fabric, which can effectively disperse the external force and improve the overall strength of the fabric. When the fabric is stretched or worn, the interlaced point can serve as a support point to prevent the veil 10 from breaking and falling off, which is particularly suitable for elastic fabrics with back hangings; at the same time, it can ensure that the veil 10 is evenly woven during the weaving process to avoid uneven thickness or inconsistent texture on the surface of the fabric. The needle cylinder hooks the back hanging yarn 20 and rotates forward and reversely to weave with half-position needles every other. It helps to enhance the air permeability of the fabric, especially in elastic fabrics with back hangings, the alternating weaving method of forward and reverse rotation makes the yarn more evenly distributed in the fabric, thereby providing uniform elastic force. This uniform elastic force enables the fabric to better restore its original state when subjected to external forces, maintaining its shape and stability. At the same time, the fabric has sufficient elasticity without causing discomfort or deformation due to excessive or insufficient elasticity.

[0060] The above-mentioned veil 10 can be a non-elastic yarn, such as cotton yarn, polyester yarn, nylon yarn, etc.; it can also be an elastic yarn, such as spandex yarn, polyester elastic yarn, nylon elastic yarn, polyester elastic yarn, mercerized elastic yarn, pure cotton elastic yarn, etc. It should be noted that when the veil 10 is an elastic yarn, its elasticity is less than that of the back yarn 20. In some embodiments, the back yarn 20 is TPU (Thermoplastic Urethane). TPU has excellent elasticity, can quickly restore to its original shape after being acted upon by external force, can withstand large tensile force, and is not easy to break due to stretching; and TPU has excellent wear resistance. Using it as a veil can resist long-term friction and wear, thereby extending the service life of the fabric.

[0061] The back-hanging yarn 20 is an elastic yarn to make the fabric with back-hanging elastic. The elastic yarn can be spandex yarn, polyester stretch yarn, nylon elastic yarn, polyester elastic yarn, mercerized elastic yarn, pure cotton stretch yarn, etc. It can also be a composite yarn, which is synthesized by two or more different yarns, combining the advantages of different yarns. In some embodiments, such as polyester and spandex (special yarns containing nylon hot melt yarn), it is suitable for making a durable and elastic back-hanging yarn 20. The composite yarn can be a twisted yarn (a yarn that is twisted to a certain extent after being combined together), an untwisted yarn (a yarn that is not twisted after being combined together), etc. In some embodiments, the composite yarn is formed by two or more different yarns being freely coupled together in parallel. In some embodiments, the composite yarn is a yarn as the yarn core, and other yarns are surrounded on the surface of the yarn core to form a core-spun yarn.

[0062] Elastic fabrics with back hanging can be used in products such as cuffs (such as sock cuffs, collar cuffs, cuffs, etc.), elastic belts (such as belts, abdominal belts, shoulder straps, sports protective gear, etc.), body shapers (tights, jumpsuits, underwear, etc.), and can also be used for clothing edge seam shaping, edge locking shaping, and hemming shaping.

[0063] The present invention also provides a back-hanging fabric, which is woven and formed by applying the weaving method of the back-hanging fabric.

[0064] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
