Description

Technical Field

[0001] The utility model relates to the field of fabrics, and particularly relates to a jacquard weft knitted fabric. Background Art

[0002] With the progress of technology and the development of society, the textile industry in our country has developed rapidly. Subsequently, the fabrics have developed rapidly, and more and more different types of fabrics have emerged. Jacquard fabric is a cotton fabric or chemical fiber blended fabric with a woven pattern, which can be divided into white woven and colored woven. It is one of the widely used fabrics among many fabrics. Jacquard fabric has the characteristics of being delicate and smooth, with beautiful patterns and distinct color levels, and strong aesthetic property, and is welcomed and loved by the majority of consumers.

[0003] Weft knitting is a weaving method in which one or several yarns are simultaneously fed along the transverse direction of the fabric and sequentially form loops by knitting needles and are strung together longitudinally to form a weft knitted fabric. Its basic principle can be summarized as the following points: Yarn feeding: The yarn is fed onto the working needles of the knitting machine along a direction approximately ninety degrees (weft direction) with respect to the fabric formation direction (warp direction). Loop formation: The yarn is sequentially bent into loops under the action of the knitting needles, and each loop is composed of a loop column and a loop arc. Loop stringing: The newly formed loops are sequentially inserted into the loops formed by the previous needle, and so on, to form a new fabric layer. As Figure 1 shown, its essence is still the appearance of V-shaped loop connection. It cannot escape the "weft knitting" knitting feeling in appearance. In recent years, the surfaces of conventional jacquard weft knitted fabrics are all in the appearance of V-shaped loop connection, and it is difficult to knit a breakthrough and innovative unconventional appearance. Summary of the Utility Model

[0004] In view of the above problems, the present application provides a jacquard weft knitted fabric for solving the problem that the existing jacquard weft knitted fabrics all have the appearance of V-shaped loop connection.

[0005] To achieve the above object, in a first aspect, the present application provides a jacquard weft knitted fabric. The jacquard weft knitted fabric is formed by knitting including a first yarn and a second yarn, and includes a jacquard area. The jacquard area includes at least one jacquard unit. In the jacquard unit, there are several loops formed by the first yarn forming loops on the front and / or back. On the surface of at least one loop, there is a floating yarn covered. The floating yarn is formed without the second yarn knitting. Among them, the loops adjacent to the floating yarn are shifted to completely expose the surface of the loop of the floating yarn.

[0006] As an implementation manner of the utility model, the jacquard area has several jacquard units, and the several jacquard units are arranged in a staggered manner.

[0007] As an implementation manner of the utility model, within the same jacquard unit, the number of loops with floating yarn covered on the surface of the loops accounts for more than 1 / 2 of the total number of loops.

[0008] As an embodiment of the present utility model, within the same jacquard unit, the number of courses of float yarn covering the surface of the coils accounts for less than 2 / 3 of the total number of courses of the coils.

[0009] As an embodiment of the present utility model, the jacquard weft knitted fabric further includes a stabilizing area. The first stabilizing area includes at least one course of first yarn forming loops on the front side and at least one adjacent course of first yarn forming loops on the back side.

[0010] As an embodiment of the present utility model, the stabilizing area includes two courses of first yarn forming loops on the front side and two adjacent courses of first yarn forming loops on the back side.

[0011] As an embodiment of the present utility model, the first yarn and the second yarn are the same kind of yarn or different kinds of yarn.

[0012] Different from the prior art, the technical solution of this application includes a jacquard area. Each jacquard area includes at least one jacquard unit. In each jacquard unit, there are several courses of loops formed by the first yarn forming loops on the front side and / or on the back side; there is at least one course of loops with float yarn covering the surface. The float yarn is formed by the second yarn not being knitted. Among them, the loops in the courses adjacent to the float yarn are loop transferred so that the float yarn completely exposes the surface of the loops, thereby enabling the float yarn to form a texture pattern, without the appearance structure of V-shaped loop connection, and deviating from the "weft knitting" knitting sense effect.

[0013] The above relevant descriptions of the utility model content are only an overview of the technical solution of this application. In order to enable those of ordinary skill in the art to more clearly understand the technical solution of this application, and then to be implemented according to the content recorded in the description and the drawings, and in order to make the above objects, other objects, features and advantages of this application more easily understood, the following is described in conjunction with the specific embodiments of this application and the drawings.

[0032] Please refer to Figure 2, this embodiment relates to a jacquard weft knitted fabric. The jacquard weft knitted fabric is formed by knitting including a first yarn and a second yarn. It includes a jacquard area 1, and the jacquard area 1 includes at least one jacquard unit 11. In the jacquard unit 11, there are several loops 4 formed by the first yarn looping on the front and / or back. On the surface of at least one loop 4, there is a float 3 covered. The float 3 is formed by the second yarn not knitting. Among them, the loops 4 adjacent to the float 3 are loop transferred so that the float 3 completely exposes the surface of the loop 4.

[0033] The above definition of the function of the first yarn for the yarn forming the loop 4 along a certain path does not limit the characteristics and quantity of the first yarn. If there are multiple yarns, the multiple yarns can have different or the same characteristics, and can be specifically selected according to requirements to enable the jacquard weft knitted fabric to have multiple functions and design schemes. The above definition of the function of the second yarn for the yarn not knitting to form the float 3 along a certain path does not limit the characteristics and quantity of the second yarn. If there are multiple yarns, the multiple yarns can have different or the same characteristics, and can be specifically selected according to requirements to enable the jacquard weft knitted fabric to have multiple functions and design schemes. Similarly, the first yarn and the second yarn can have different or the same characteristics, and the quantity can be the same or different. The above characteristics refer to yarn color, material, elasticity, etc. Different from the prior art, the technical solution of this application includes a jacquard area 1. Each jacquard area 1 includes at least one jacquard unit 11. Each jacquard unit 11 includes at least one path of the first yarn looping on the front to form a loop 4, and at least one path of the second yarn not knitting to form a float 3. Among them, the second yarn does not knit to form a float 3, and the loop 4 at the adjacent position of the first yarn looping on the front to form a loop 4 and the float 3 is loop transferred to the back, so that the float 3 is completely exposed, and further the float 3 forms a texture pattern, without the appearance structure of the V-shaped loop 4 connection, and breaks away from the "weft knitting" knitting sense effect.

[0034] The above jacquard area 1 includes a jacquard unit 11, and can also include other units other than the jacquard unit 11, such as existing conventional tissues, regular or irregular tissues formed by alternating loop formation, tuck stitch, float, etc.

[0035] There can be several jacquard units 11 in the above jacquard area 1. The several jacquard units 11 can be arranged at intervals or adjacent to each other. The arrangement method can be that several units are arranged in one row or multiple rows, or several units are arranged in one column or multiple columns, or several units are arranged in a geometric figure or a non-geometric figure (such as a polygon, a flower shape, etc.); of course, it can also be that several of the jacquard units 11 are arranged in a staggered manner.

[0036] Within the same jacquard unit 11, the number of courses of floats 3 covering the surface of the loops 4 is not limited. In some embodiments, the number of courses of floats 3 covering the surface of the loops 4 is more than 1 / 2 of the total number of courses of the loops 4. In some embodiments, the number of courses of floats 3 covering the surface of the loops 4 is less than 2 / 3 of the total number of courses of the loops 4. Within the same jacquard unit 11, the ratio of the number of courses of floats 3 covering the surface of the loops 4 to the number of courses of the loops 4 not covered by floats 3 on the surface of the loops 4 is limited within a certain range. The first yarn and the second yarn are interwoven with each other according to a predetermined ratio to ensure the configuration balance of the first yarn and the second yarn, control the balance of the front and back loops 4, and keep the jacquard unit 11 stable.

[0037] To make the jacquard weft knitted fabric more stable, the jacquard weft knitted fabric further includes a stabilizing area 2, and the stabilizing area 2 can be arranged around the jacquard area 1. Specifically, the stabilizing area 2 includes at least one course of the first yarn forming loops 4 by knitting on the front side and at least one adjacent course of the first yarn forming loops 4 by knitting on the back side. In some embodiments, the above-mentioned stabilizing area 2 may include one course of the first yarn forming loops 4 by knitting on the front side and one adjacent course of the first yarn forming loops 4 by knitting on the back side. In some embodiments, the above-mentioned stabilizing area 2 may include two courses of the first yarn forming loops 4 by knitting on the front side and two adjacent courses of the first yarn forming loops 4 by knitting on the back side. Of course, in some embodiments, the stabilizing area 2 includes at least one course of loops 4 formed by knitting alternately front and back.

[0038] The above-mentioned first yarn and second yarn can be the same kind of yarn or two different kinds of yarns. Both the first yarn and the second yarn can use composite filaments.

[0039] The fabric woven from the above-mentioned composite filaments is a composite filament fabric, which is a fabric woven from two or more different fibers. During the blending process, each fiber is processed into fine strands and then combined and interwoven through a weaving process to form a composite filament fabric with various properties. Common composite filament fabrics include blended fabrics such as polyester-cotton, polyester, cotton-linen, etc., and fabrics blended with polyester fiber and silk. The composite filament fabric has the advantages of good abrasion resistance, high strength, good wrinkle resistance, good air permeability, good waterproofness, and bright colors.

[0040] The following provides several implementation modes for knitting the above-mentioned jacquard weft knitted fabric. The mechanical equipment for weaving the fabric is a jacquard machine with a loop transfer function, and a jacquard machine with 14 needles is used.

[0041] Embodiment 1: 8 courses form a cycle. The first yarn and the second yarn are arranged continuously to set the jacquard area 1. The first yarn is arranged in the front for 4 consecutive courses, so that the first yarn forms loops 4 on the front side. After the first yarn forms loops on the front side, it transfers the loops to the back side and continues to form loops. In the following 4 courses, the second yarn is additionally arranged. The second yarn does not knit to form 4 consecutive floating yarns 3. The loops 4 at the adjacent position of the loops 4 formed by the first yarn forming loops on the front side and the floating yarns 3 transfer the loops to the back side, and the floating yarns 3 are exposed and cover the surface of the loops 4. The covered area of the floating yarns 3 constitutes the horizontal area of the jacquard unit 11, and the non-covered area of the floating yarns 3 constitutes the vertical area of the jacquard unit 11.

[0042] In the vertical area, the first yarn forms loops normally on the front side. In terms of the order of yarn arrangement and knitting, there is no second yarn on the back side of the first yarn. However, in the actual weaving process, the reason for the inevitable connection of the back-side loops 4 involves some second-yarn loops 4 to fill the empty loops 4 on the back side of the vertical area. When transitioning from the vertical area to the horizontal area, all the front-side loops 4 of the first yarn are transferred to the back side; after the front-side loops of the first yarn in the horizontal area are transferred, they continue to form loops, and the second yarn continuously forms floating yarns 3, which are exposed on the surface of the loops 4 formed after the first yarn transfers the loops.

[0043] When transitioning from the vertical area to the horizontal area, loop transfer is required to reduce the loops 4 on the front side of the fabric surface. When transitioning from the horizontal area to the vertical area, the first yarn needs to be empty-knit to continue knitting to form loops 4. Therefore, the number of loops 4 on the front side of the fabric surface will decrease, resulting in an enlarged gap between the loops 4 in the knitting area of the second yarn on the overall front side. The floating yarn 3 part is thinner and lighter than the conventional double-sided fabric and has better breathability.

[0044] See Figure 2 As shown, Embodiment 2: The loops 4 adopt a 16-course cycle. The first yarn is arranged in the 1st - 12th courses to form the vertical area, and the second yarn is additionally arranged in the 13th - 16th courses to form the horizontal area. Among them, the 1st - 8th courses are the stable area 2, and the stable area 2 plays a supporting role for the fabric. The 13th - 16th courses are the jacquard area 1. In the 1st - 2nd courses, the first yarn forms loops at intervals on the front and back sides to keep the loops 4 on the front and back sides balanced. In the 3rd - 4th courses, the first yarn forms loops on the front side. In the 6th - 8th courses, the first yarn forms loops on the back side, and the second yarn forms loops on the front side. In the 9th - 11th courses, the first yarn forms loops on the front side. Finally, in the 12th course, after forming loops on the front side, it transfers the loops to the back side; the second yarn in the horizontal area forms 4 consecutive floating yarns 3. Since the front-side loops 4 have been transferred in advance, the floating yarns 3 are directly exposed on the surface of the loops 4.
