Description

TECHNICAL FIELD

[0001] The utility model relates to cloth field, especially a one side convex one side concave bubble cloth. BACKGROUND

[0002] In the field of clothing, home textiles, decorative fabrics, three-dimensional convex structure is the key direction of functional textile fabric to improve added value, which can meet the multiple needs of consumers for product aesthetics, comfort and functionality.

[0003] The existing textile fabric has obvious limitations: most conventional fabrics are pure plane structure, lack effective three-dimensional convex design, can only realize basic coverage and warmth function, and lacks three-dimensional level, which limits its promotion in medium and high-end scenarios.

[0004] To achieve a three-dimensional effect, some fabrics are processed by raising, crepe, jacquard and embossing processes, but there are many technical defects: the raising process has poor consistency in pile density and length, resulting in insufficient delicate touch; the three-dimensional shape of the crepe process has poor regularity and durability, and is easily deformed after being subjected to external force or washing; the convexity of the jacquard process is mostly concentrated in local patterns, with uneven support layout and single shape, making it difficult to achieve balanced elastic support in all directions; the embossing process has poor consistency in convexity and concavity due to the difficulty in controlling pressure parameters, and the formed structure has poor flexibility and rebound performance. In addition, these three-dimensional fabrics also have poor comfort, heavy fabric, poor flexibility, air permeability and elasticity.

[0005] These deficiencies result in that the existing textile fabric with three-dimensional convex structure cannot form an ideal balance between three-dimensional shape stability, touch comfort, air permeability and elastic support, limiting the application expansion and quality improvement of functional textile fabric. INVENTION CONTENTS

[0006] The utility model solves the technical problem of providing a one side convex one side concave bubble cloth, which has stable three-dimensional shape, delicate and uniform touch, good air permeability and elastic support performance, and good fabric flexibility, effectively expanding the application scenarios of functional textile fabric.

[0007] To solve the above technical problems, the technical scheme adopted is as follows:

[0008] A one side convex one side concave bubble cloth, characterized by comprising a base cloth layer and an elastic layer, the base cloth layer is provided with a plurality of bubble generating areas, the elastic layer comprises a plurality of elastic yarns, each elastic yarn is interwoven and fixed on the base cloth layer, and the elastic yarns bypass the bubble generating areas; the positions corresponding to the bubble generating areas on the base cloth layer form a bubble structure with one side convex and the other side concave.

[0009] The plurality of bubble forming areas of the base fabric layer provide a basic form for bubble formation, and the elastic yarns are densely interwoven and fixed on the base fabric layer and bypass the bubble forming areas, so that the edges of the bubble forming areas are contracted under the elastic force of the elastic yarns, thereby naturally forming a plurality of bubble structures with one side protruding and the other side recessed on the base fabric layer. This bubble fabric can not only retain the softness and flexibility of the textile fabric, but also enhance the three-dimensional level through the bubble structure. Moreover, since the bubble forming areas do not need to interweave elastic yarns, a natural ventilation channel can be formed, effectively optimizing the ventilation performance of the fabric. Meanwhile, the uniformly distributed bubble structure can cooperate with the elastic yarns to provide balanced elastic support performance. Therefore, the bubble fabric can be adapted to multiple scenes such as clothing, home decoration, and daily necessities, and is comfortable to wear or use. It can balance the three-dimensional texture and practical performance without additional processes, and the structure design is simple and reasonable, and the production and processing are convenient, which can easily meet the multiple demands of high-end fabrics for texture, comfort and functionality.

[0010] In a preferred embodiment, the bubble structure is in the shape of a spherical cap. The bubble forming area is a plurality of circular areas (usually, the diameter of the circular area is 0.8-1.2 cm) divided on the base fabric layer. After the elastic yarns are interwoven on the base fabric layer, each circular bubble forming area can be contracted into a spherical cap-shaped bubble with one side protruding and the other side recessed.

[0011] In a preferred embodiment, each bubble structure is distributed in an array.

[0012] In a preferred embodiment, the bubble fabric is knitted by a double-sided knitting machine, and the bubble fabric is knitted in 6 rows per cycle. The first and second rows are flat knitting on the lower base fabric layer, the third and fourth rows are flat knitting on the upper base fabric layer, and the fifth and sixth rows are rib knitting on the elastic layer. The lower needle cylinder of the double-sided knitting machine uses 16 needle pitches, and the upper needle disc uses 14 needle pitches. The base fabric layer is knitted by the first to fourth rows, and the knitted yarn is 40S combed cotton. The elastic layer is knitted by the fifth and sixth rows, and the knitted yarn is 40D spandex. The base fabric layer is knitted by the first to fourth rows, which can ensure uniform knitting density, natural structure connection between the bubble forming area and the conventional area, stable basis for bubble structure formation, and soft and breathable 40S combed cotton material to ensure skin-friendly performance. The fifth and sixth rows of the elastic layer are rib knitted, which is suitable for the elastic properties of 40D spandex, so that the elastic yarns are more stable, the bubble structure is regular and the shape is not easy to deform, the interweaving firmness with the base fabric layer is enhanced, and the elastic yarns can bypass the bubble forming area accurately. Usually, the base fabric layer is knitted more sparsely, so that the bubble structure can form a ventilation hole after formation.

[0013] In a further preferred embodiment, the 40S combed cotton has a loop length of 200-220 MM / 100G. The loop length is suitable for the knitting process of the lower plain stitch and the upper plain stitch of the base fabric layer, ensures that the base fabric layer has a dense conventional area structure, and at the same time, reserves a reasonable deformation space for the bubble generating area, avoids that the base fabric layer is loose due to the too long loop, and limits the bubble structure to protrude due to the too short loop, ensures that the heights of the various bubble structures are uniform, and the three-dimensional level of the fabric is more prominent.

[0014] In a further preferred embodiment, when the elastic layer is knitted by the 5th-6th path, the 40D spandex is fed in parallel by two yarns. The parallel feeding of the two 40D spandex yarns can enhance the interlacing strength and the constraint ability of the elastic layer, makes the conventional area of the base fabric layer more stable, avoids that the bubble structure is displaced or the fabric is loose due to the insufficient tension of a single yarn, makes the constraint effect of the elastic layer more durable, and the bubble structure is not easily deformed due to external pulling, and the overall structure of the fabric is more compact.

[0015] In a further preferred embodiment, the 40D spandex has a loop length of 100-110 MM / 100G. The loop length is suitable for the rib knitting process of the elastic layer, ensures that the elastic yarn is interlaced tightly and has balanced elasticity, can effectively constrain the base fabric layer, and will not cause the fabric to be stiff due to the too short loop, or the elasticity to be relaxed and the bubble structure to be unable to be formed due to the too long loop, ensures that the bubble structure is stable in shape, and at the same time, can enhance the fit of the elastic layer and the base fabric layer, and improve the wearing or using comfort.

[0016] In a further preferred embodiment, the double-sided knitting machine has a gauge of 32 inches and a needle cylinder diameter of 32 inches.

[0017] The air bubble fabric has the advantages that the three-dimensional shape of the air bubble fabric is stable, the touch is delicate and uniform, the air permeability and the elastic support performance are good, the fabric flexibility is considered, and the application scene of the functional textile fabric is effectively expanded. BRIEF DESCRIPTION OF DRAWINGS

[0018] Fig. 1 FIG. 1 is a structural schematic view of an air bubble fabric according to an embodiment of the present application;

[0019] Fig. 2 FIG. 2 is a sectional view of the air bubble fabric according to the embodiment of the present application. DETAILED DESCRIPTION

[0020] The present application will be further described in combination with the drawings and specific embodiments:

[0021] As Figs. 1-2The one-side convex and one-side concave bubble cloth shown includes a base cloth layer 1 and an elastic layer 2, the base cloth layer 1 is provided with a plurality of bubble forming areas, the elastic layer 2 includes a plurality of elastic yarns, each elastic yarn is respectively interwoven and fixed on the base cloth layer 1, and the elastic yarns bypass each bubble forming area; the positions corresponding to each bubble forming area on the base cloth layer 1 constitute a bubble structure 3 which is convex on one side and concave on the other side.

[0022] In the above bubble cloth, the plurality of bubble forming areas provided on the base cloth layer 1 provide a basic form for bubble forming, the elastic yarns are densely interwoven and fixed on the base cloth layer 1 and bypass each bubble forming area, so that the edges of each bubble forming area shrink under the elastic force of the elastic yarns, thereby naturally forming a plurality of bubble structures 3 which are convex on one side and concave on the other side on the base cloth layer 1. This bubble cloth can not only retain the softness and flexibility of the textile fabric, but also improve the three-dimensional level through the bubble structure 3, and because the bubble forming area does not need to interweave the elastic yarn, it can form a natural ventilation channel, effectively optimizing the air permeability of the fabric, and the uniformly distributed bubble structure 3 can cooperate with the elastic yarn to provide balanced elastic support performance; Therefore, the bubble cloth can be adapted to multiple scenes such as clothing, home decoration, and commodity fabrics, and is comfortable to wear or use, and can balance the three-dimensional texture and practical performance without additional process, and the structure design is simple and reasonable, and the production and processing are convenient, which can easily meet the multiple demands of high-end fabrics for texture, comfort and functionality.

[0023] The bubble structure 3 is in the shape of a spherical cap, and each bubble structure 3 is distributed in an array. The bubble forming area is a plurality of circular areas (usually, the diameter of the circular area is 0.8-1.2cm) divided on the base cloth layer 1, after the elastic yarns are interwoven on the base cloth layer 1, each circular bubble forming area can shrink into a spherical cap-shaped bubble which is convex on one side and concave on the other side.

[0024] The bubble cloth is knitted by a double-sided knitting machine. The bubble cloth takes 6 routes as one cycle, wherein the first and second routes are lower plain knitting of base cloth layer 1, the third and fourth routes are upper plain knitting of base cloth layer 1, and the fifth and sixth routes are rib knitting of elastic layer 2. The lower needle cylinder of the double-sided knitting machine uses 16 needle pitches, and the upper needle disc uses 14 needle pitches. The base cloth layer 1 is knitted by the first to fourth routes, and the knitting yarn is 40S combed cotton. The elastic layer 2 is knitted by the fifth to sixth routes, and the knitting yarn is 40D spandex. The base cloth layer 1 is knitted by the first to fourth routes, which can ensure that the overall knitting density is uniform, the bubble generation area and the conventional area structure are naturally connected, and a stable foundation is provided for the formation of the bubble structure 3. The 40S combed cotton is soft and breathable, which ensures the skin-friendliness of the fabric. The elastic layer 2 is knitted by the fifth to sixth routes, which is suitable for the elastic properties of 40D spandex, so that the elastic yarn is more stable, the bubble structure 3 is formed regularly and the shape is not easy to deform, the interweaving firmness with the base cloth layer 1 is enhanced, and the elastic yarn can accurately bypass the bubble generation area. Generally, the base cloth layer is knitted more sparsely, so that the bubble structure 3 can form a breathable hole after forming.

[0025] The loop length of 40S combed cotton is 200-220MM / 100G. This loop length is suitable for the knitting process of the base cloth layer 1, which ensures that the conventional area structure of the base cloth layer 1 is dense, and at the same time, a reasonable deformation space is reserved for the bubble generation area, avoiding the overlong loop length leading to the looseness of the base cloth layer 1 and the limitation of the bubble structure 3, ensuring that the protrusion height of each bubble structure 3 is uniform and consistent, and the fabric has more prominent three-dimensional level.

[0026] When the elastic layer 2 is knitted by the fifth to sixth routes, the 40D spandex is fed in double yarns in parallel. The double 40D spandex knitting in parallel can enhance the interweaving strength and constraint ability of the elastic layer 2, make the conventional area of the base cloth layer 1 more stable, avoid the displacement of the bubble structure 3 or the looseness of the fabric due to insufficient tension of single yarn, make the constraint effect of the elastic layer 2 more durable, and prevent the bubble structure 3 from deforming due to external force, so that the overall structure of the fabric is more compact.

[0027] The loop length of 40D spandex is 100-110MM / 100G. This loop length is suitable for the rib knitting process of the elastic layer 2, which ensures that the elastic yarn is interwoven tightly and the elasticity is balanced, which can effectively constrain the base cloth layer 1, and will not cause the fabric to be stiff due to the overlong loop length, or the elasticity to be relaxed and the bubble structure 3 to be unable to form due to the overlong loop length, ensuring the stability of the bubble structure 3; at the same time, it can also enhance the fit of the elastic layer 2 and the base cloth layer 1, and improve the wearing or using comfort.

[0028] The machine gauge of the double-sided knitting machine is 32 inches, and the needle cylinder diameter is 32 inches.
