Description

Technical Field

[0001] The present application relates to the field of textiles, and in particular to a single-sided velvety weft-knitted double-sided jacquard fabric, a preparation method and applications thereof. Background Art

[0002] Currently, weft-knitted velvet fabrics are mostly woven using special machines such as loop pile machines, towel machines, and sweatshirt machines. The velvet fabrics are then processed through various finishing processes such as napping, combing, shearing, and polarizing to produce the velvet fabrics. The raising process often destroys the yarn structure itself, which affects its warmth retention and shortens the service life of the fabric. For example, Chinese patent application number 202010029795.4 discloses a velvet fabric obtained by brushing a weft-knitted sandwich fabric to destroy the surface yarn structure. Summary of the Invention

[0003] In view of the above problems, the present application provides a single-sided velvety weft-knitted double-sided jacquard fabric and a preparation method thereof. The single-sided velvety weft-knitted double-sided jacquard fabric is directly woven on a double-sided jacquard double-transfer jacquard machine. After simple finishing, the outer yarn of the air-wrapped yarn is curled, the fluffiness is increased, and the fabric has a velvety feel. At the same time, the yarn structure itself does not need to be destroyed, and the structure is stable and the service life is long.

[0004] To achieve the above-mentioned object, in a first aspect of the present invention, the applicant provides a method for preparing a single-sided velvety weft-knitted double-sided jacquard fabric, comprising the following steps:

[0005] Weaving: A double-sided jacquard machine is used to weave weft-knitted double-sided jacquard fabric; the front side of the weft-knitted double-sided jacquard fabric is a pile surface, woven with air-covered yarn, the core yarn of the air-covered yarn is a high-elastic yarn; the back side is woven with a high-shrinkage yarn;

[0006] Finishing: The weft-knitted double-sided jacquard fabric is finished at high temperature, and the high-shrinkage yarn on the back of the fabric shrinks at high temperature, causing the core yarn of the air-covered yarn on the front of the fabric to shrink and the outer yarn to curl, forming a velvet feel; after fixing, a single-sided velvet-feel weft-knitted double-sided jacquard fabric is obtained.

[0007] Different from the existing technology, the above technical solution uses air-wrapped yarn with high-elastic yarn as the core yarn and high-shrinkage yarn to weave the front and back of the weft-knitted double-sided jacquard fabric respectively. During the finishing step, the shrinkage of the high-shrinkage yarn causes the core yarn to shrink. While the outer yarn of the air-wrapped yarn remains unchanged in length, due to the shrinkage of the core yarn, it will extend and curl relative to the core yarn position (i.e., perpendicular to the fabric surface), achieving a velvety effect. In this technical solution, the structure of the air-wrapped yarn is intact and undamaged, which increases the service life of the fabric. The structure is more compact and stable than that of ordinary double-sided weft-knitted fabrics, providing strong support.

[0008] In some embodiments, the reverse side is woven with high shrinkage yarn and low shrinkage yarn.

[0009] In some embodiments, the mass ratio of the low shrinkage yarn to the high shrinkage yarn is 8-12:16-25.

[0010] In some embodiments, the high shrinkage yarn is woven into a plaited weave on the reverse side.

[0011] In some embodiments, the high shrinkage yarn shrinks by 25%-30% at the shrinkage temperature, and the low shrinkage yarn shrinks by 6-7% at the shrinkage temperature.

[0012] In some embodiments, the weaving step adopts a double-sided jacquard machine with 4 needle paths for circular weaving, the jacquard area is a plain jacquard, the dial needles are arranged in a 12-needle pattern, and the cylinder needles are arranged in a 21-needle pattern; the cam configuration is as follows:

[0013]

[0014] In some embodiments, 2 and 4 routes use air-covered yarn; 1 route uses low-shrinkage yarn; and 3 route uses a mixture of low-shrinkage yarn and high-shrinkage yarn.

[0015] In some embodiments, the weaving step adopts a double-sided jacquard double-transfer jacquard machine with 16 needle paths for circular weaving; the jacquard area is a mesh jacquard; the needle dial adopts a 1232 needle arrangement method, and the needle cylinder adopts a 1232 needle arrangement method; the cam configuration is as follows:

[0016]

[0017]

[0018] Among them, the dial needle transfers the circle to the 3rd needle of route 1 and the 1st needle of route 9.

[0019] In some embodiments, 2, 4, 6, 8, 10, 12, 14, and 16 routes use air-covered yarn; 1, 7, 9, and 15 routes use low-shrinkage yarn; and 3, 5, 11, and 13 routes use a mixture of low-shrinkage yarn and high-shrinkage yarn.

[0020] In some embodiments, the yarn feeding length on the front side of the weft-knitted double-sided jacquard fabric is greater than the yarn feeding length on the back side.

[0021] In some embodiments, the shrinkage temperature is 180-200°C.

[0022] In a second aspect of the present invention, the applicant provides a single-sided velvet-feel weft-knitted double-sided jacquard fabric, which is woven using the method of the first aspect of the present invention.

[0023] Unlike existing technologies, this solution utilizes air-wrapped yarn with a high-elasticity yarn as the core yarn and high-shrinkage yarn to weave the front and back of a weft-knitted double-sided jacquard fabric. Through the finishing process, the shrinkage of the high-shrinkage yarn on the back of the fabric drives the core yarn in the air-wrapped yarn on the front to retract, causing the outer yarn to curl and create a velvety feel. The air-wrapped yarn maintains its structural integrity and is undamaged, extending the fabric's lifespan. Compared to conventional double-sided weft-knitted fabrics, the structure is more compact, providing greater stability and support. After the shoe upper has been treated at a shrinking temperature, the yarn shrinkage is reduced, preventing deformation under stress.

[0024] In the third aspect of the present invention, the applicant provides the use of the single-sided velvety weft-knitted double-sided jacquard fabric described in the second aspect of the present invention in the preparation of shoe upper materials.

[0025] As the uses of textiles become increasingly diverse, more textiles are being used in shoe uppers. People's expectations for the appearance of shoe uppers are also becoming increasingly demanding. A variety of design effects are being applied to shoe uppers; however, as shoe upper materials, they require strong structural support, which current weft-knitted fabrics struggle to provide.

[0026] The shoe upper material of this technical solution provides strong structural support and minimal deformation during movement, effectively controlling the upper's extensibility and preventing deformation during use. In existing technologies, due to the certain stretchability of yarns, the corresponding woven uppers also have high extensibility. As a result, the upper is easily deformed under stress during movement, reducing its coverage and protection for the foot, and causing discomfort when worn.

[0027] The above-mentioned records related to the invention content are only an overview of the technical solution of this application. In order to enable ordinary technicians in this field to more clearly understand the technical solution of this application, and then implement it according to the written contents of the specification, and to make the above-mentioned purposes and other purposes, features and advantages of this application easier to understand, the following is an explanation in combination with the specific implementation methods of this application. DETAILED DESCRIPTION

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments.

The appearance of the word "embodiment" in various places in the specification does not necessarily refer to the same embodiment, nor does it particularly limit its independence or relevance to other embodiments. In principle, in this application, as long as there are no technical contradictions or conflicts, the various technical features mentioned in the embodiments can be combined in any manner to form a corresponding implementable technical solution.

[0031] Unless otherwise defined, the technical terms used herein have the same meanings as those generally understood by those skilled in the art to which this application belongs; the use of relevant terms herein is only for describing specific embodiments and is not intended to limit this application.

[0032] In the description of this application, the term "and / or" is used to describe a logical relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A exists, B exists, and both A and B exist. In addition, the character " / " in this document generally indicates that the objects before and after are in a logical "or" relationship.

[0033] In this application, terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual quantity, priority or sequence relationship between these entities or operations.

[0034] Without further limitations, in this application, the words "include", "comprise", "have" or other similar expressions used in the sentences are intended to cover non-exclusive inclusion. These expressions do not exclude the presence of additional elements in the process, method or product including the elements, so that the process, method or product including a series of elements may include not only those defined elements, but also other elements not explicitly listed, or elements inherent to such process, method or product.

[0035] Consistent with the understanding in the Examination Guidelines, in this application, expressions such as "greater than," "less than," and "exceed" are understood to exclude the number itself; expressions such as "above," "below," and "within" are understood to include the number itself. Furthermore, in the description of the embodiments of this application, "multiple" means more than two (including two), and similar expressions related to "multiple" are also understood in this manner, such as "multiple groups," "multiple times," etc., unless otherwise specifically defined.

[0036] The air-covered yarn described in this application is a yarn in which the outer yarn and the core yarn are simultaneously drawn through a nozzle of a certain size, and a rhythmic network of dots is formed by the regular spray pressure of highly compressed air. In the air-covered yarn structure, the outer yarn is relatively loosely wrapped around the core yarn.

[0037] The low shrinkage yarn described in the present application is a conventional yarn, and the shrinkage range of the conventional yarn at the shrinkage temperature is 6-7%.

[0038] To achieve the above-mentioned object, in a first aspect of the present invention, the applicant provides a method for preparing a single-sided velvety weft-knitted double-sided jacquard fabric, comprising the following steps:

[0039] Weaving: A double-sided jacquard machine is used to weave weft-knitted double-sided jacquard fabric; the front side of the weft-knitted double-sided jacquard fabric is a pile surface, woven with air-covered yarn, the core yarn of the air-covered yarn is a high-elastic yarn; the back side is woven with a high-shrinkage yarn;

[0040] Finishing: The weft-knitted double-sided jacquard fabric is finished at high temperature, and the high-shrinkage yarn on the back of the fabric shrinks at high temperature, causing the core yarn of the air-covered yarn on the front of the fabric to shrink and the outer yarn to curl, forming a velvet feel; after fixing, a single-sided velvet-feel weft-knitted double-sided jacquard fabric is obtained.

[0041] Different from the existing technology, the above technical solution uses air-wrapped yarn with high-elastic yarn as the core yarn and high-shrinkage yarn to weave the front and back of the weft-knitted double-sided jacquard fabric respectively. During the finishing step, the shrinkage of the high-shrinkage yarn causes the core yarn to shrink. While the outer yarn of the air-wrapped yarn remains unchanged in length, due to the shrinkage of the core yarn, it will extend and curl relative to the core yarn position (i.e., perpendicular to the fabric surface), achieving a velvety effect. In this technical solution, the structure of the air-wrapped yarn is intact and undamaged, which increases the service life of the fabric. The structure is more compact and stable than that of ordinary double-sided weft-knitted fabrics, providing strong support.

[0042] In some embodiments, the fabric is fixed by applying a certain pressure combined with high temperature, and the pressure can generally be selected to be 30-50N.

[0043] In some preferred embodiments, the outer yarn of the air covered yarn is low-elastic or non-elastic yarn. Too high elasticity of the outer yarn will reduce its curling effect. The low-elastic or non-elastic setting can increase the fluffiness and density of the outer yarn after finishing, and enhance the velvety feeling.

[0044] In some embodiments, the reverse side is woven with high shrinkage yarn and low shrinkage yarn.

[0045] In some embodiments, when weaving the reverse side, the mass ratio of the low-shrinkage yarn to the high-shrinkage yarn is 8-12:16-25. This arrangement can prevent the fabric from shrinking excessively, resulting in a shapeless fabric, or from shrinking insufficiently, resulting in a less noticeable velvety effect on the reverse side.

[0046] In some embodiments, the high shrinkage yarn is woven into a plating weave on the reverse side. The plating weave structure can wrap the high shrinkage yarn in the middle of the fabric, preventing it from being exposed on the surface of the fabric, thereby preventing the high shrinkage yarn from overflowing during subsequent dyeing and finishing processes.

[0047] In some embodiments, the high shrinkage yarn shrinks by 25%-30% at the shrinkage temperature, and the low shrinkage yarn shrinks by 6-7% at the shrinkage temperature.

[0048] In some embodiments, in the weaving step, the jacquard area is plain jacquard, and a double-sided jacquard machine with 4 needle paths is used for circular weaving. The dial needles are arranged in a 12-way pattern, and the cylinder needles are arranged in a 21-way pattern. The cam configuration is as follows:

[0049]

[0050] In some embodiments, 2 and 4 routes use air-covered yarn; 1 route uses low-shrinkage yarn; and 3 route uses a mixture of low-shrinkage yarn and high-shrinkage yarn.

[0051] In some embodiments, the weaving step adopts a double-sided jacquard machine with 16 needle paths for circular weaving; the jacquard area is a mesh jacquard; the needle dial needles adopt a 1232 needle arrangement method, and the needle cylinder adopts a 1232 needle arrangement method; the cam configuration is as follows:

[0052]

[0053] Among them, the needle dial needle transfers the circle at the 3rd needle of route 1 and the 1st needle of route 9 to form a mesh.

[0054] In some embodiments, 2, 4, 6, 8, 10, 12, 14, and 16 routes use air-covered yarn; 1, 7, 9, and 15 routes use low-shrinkage yarn; and 3, 5, 11, and 13 routes use a mixture of low-shrinkage yarn and high-shrinkage yarn.

[0055] In some embodiments, the yarn feed length on the front side of the weft-knitted double-sided jacquard fabric is greater than the yarn feed length on the back side. In this way, the yarn feed length on the front side during weaving is larger, which can increase the stacking effect of the yarn on the front side and thus increase the velvet feel of the fabric.

[0056] In some embodiments, the shrinkage temperature is 180-200°C.

[0057] In a second aspect of the present invention, the applicant provides a single-sided velvet-feel weft-knitted double-sided jacquard fabric, which is woven using the method of the first aspect of the present invention.

[0058] Unlike existing technologies, this solution utilizes air-wrapped yarn with a high-elasticity yarn as the core yarn and high-shrinkage yarn to weave the front and back of a weft-knitted double-sided jacquard fabric. Through a finishing step, the shrinkage of the high-shrinkage yarn on the back side of the fabric drives the core yarn in the air-wrapped yarn on the front side back, causing the outer yarn of the air-wrapped yarn to curl, creating a velvety feel. The air-wrapped yarn maintains its structural integrity and is undamaged, extending the fabric's lifespan. Compared to conventional double-sided weft-knitted fabrics, the structure is more compact, providing greater stability and support. After the shoe upper has been treated at a shrinking temperature, the yarn shrinkage is reduced, preventing deformation under stress.

[0059] In a third aspect of the present invention, the applicant provides the use of the single-sided velvety weft-knitted, double-sided jacquard fabric described in the second aspect of the present invention in the preparation of a shoe upper material. The shoe upper material in this technical solution provides strong structural support and minimal deformation during movement, effectively controlling the extensibility of the shoe upper and preventing deformation during use. In the prior art, due to the certain stretchability of yarns, the corresponding woven shoe upper also has high extensibility. Therefore, during exercise, the shoe upper is easily deformed by stress, reducing the shoe upper's coverage and protection for the foot, and causing discomfort when worn.
