Description

Technical Field

[0001] The utility model relates to a novel elastic core-spun yarn and a fabric, belonging to the field of textiles. Background Art

[0002] Since its arrival on the textile scene, denim has undergone significant development over the years. The emergence of various functional yarns has transformed denim from its traditionally rugged, stiff cotton counterpart into a versatile and versatile offering. Driven by the consumer market, denim is beginning to feature elasticity, a close-fitting fit, and comfort and softness. With changing lifestyles, exercise has become a popular way for people to stay healthy. Elastic denim is particularly well-suited for light exercise during leisure time, making it suitable for everyday wear without the need for dedicated sportswear. Prior art stretch denim is primarily made from elastic yarn. To minimize damage to the elastic fibers, these yarns typically employ a core-spun structure, with a protective sheath wrapped around the core. This core-spun yarn can be easily broken by excessive stretching during exercise or repeated washing and friction at home, exposing the elastic yarn and causing a loss of elasticity. This impacts the garment's lifespan and limits the development of stretch denim in the leisure and sportswear market. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a more durable novel elastic core-spun yarn and a fabric made from the novel elastic core-spun yarn.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] In the first aspect, the present application provides a new type of elastic core-spun yarn, comprising a yarn core and a covering layer wrapped around the yarn core, the covering layer comprising a vinylon layer directly covering the yarn core and a woven yarn layer wrapped around the vinylon layer, the woven yarn layer comprising bamboo fiber yarn and cotton fiber yarn, the bamboo fiber yarn and the cotton fiber yarn are overlapped and woven into a tubular woven yarn layer covering the vinylon layer.

[0006] The outer layer of the new elastic core-spun yarn provided by the present application has a woven structure. The friction force at the woven points can be used to increase the elasticity of the yarn and the number of times the yarn can be stretched. When the entire yarn is stretched, the woven yarn layer is deformed (quadrilateral instability) and friction occurs at the woven points (the overlapping points of the bamboo fiber yarn and the cotton fiber yarn), sharing the tension that the yarn core has to bear, which is beneficial to improving the durability of the elastic core-spun yarn. After washing with hot water, the vinylon layer will completely or partially dissolve, leaving a gap between the woven yarn layer and the yarn core. When the user wears the fabric containing the yarn core for exercise, the gap left by the vinylon layer cooperates with the woven yarn core layer to facilitate the transfer of sweat and air, thereby reducing the feeling of stuffiness.

[0007] In some embodiments, the braided yarn layer includes a total of 12 pieces of the bamboo fiber yarn and the cotton fiber yarn, which has a better protection effect on the yarn core and prevents the braided yarn layer from being too loose.

[0008] In a preferred embodiment, one of the bamboo fiber yarn and the cotton fiber yarn is spirally wound around the vinylon layer in a clockwise direction, and the other is spirally wound around the vinylon layer in a counterclockwise direction.

[0009] In a more preferred embodiment, the braided yarn layer is woven from 6 bamboo fiber yarns and 6 cotton fiber yarns.

[0010] In some embodiments, the yarn core is T400 fiber with a denier of 70D~150D, which can avoid a large difference in elasticity between the yarn core and the braided yarn layer, and avoid the yarn as a whole being too loose or too tight to cause kinking, which is beneficial to ensuring the quality of the yarn.

[0011] In a preferred embodiment, the yarn core is 100D T400 fiber.

[0012] In some embodiments, the count of the bamboo fiber yarn is 16S, and the count of the cotton fiber yarn 32 is 16S.

[0013] In some embodiments, the novel elastic core-spun yarn has a count of 7S.

[0014] In a second aspect, the present application provides a fabric comprising the novel elastic core-spun yarn as described in the first aspect. The elasticity of the fabric is less likely to decay and is conducive to air permeability and moisture conduction of the fabric.

[0015] Furthermore, the fabric is a woven fabric, including interwoven warp yarns and weft yarns, the warp yarns and weft yarns are interwoven in a three-up-one-down structure, and the weft yarn is the new elastic core-spun yarn as described in the first aspect, so that the new elastic core-spun yarn is applied in denim fabrics.

[0016] The beneficial effects of the present invention are as follows: the outer layer of the novel elastic core-spun yarn of the present invention has a woven structure. When the entire yarn is stretched, the woven yarn layer is deformed and friction occurs at the woven points, which can share the tension that the yarn core has to bear, and is beneficial to improving the elasticity and service life of the elastic core-spun yarn; after washing with hot water, the vinylon layer will be completely or partially dissolved, leaving a gap between the woven yarn layer and the yarn core. When exercising while wearing a fabric containing the yarn core, the gap left by the vinylon layer cooperates with the woven yarn core layer to facilitate the transmission of sweat and air, thereby reducing the feeling of stuffiness.

[0017] Other features and advantages of the present application will be described in the following description, and in part will become apparent from the description, or understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained by the structures particularly pointed out in the written description and the drawings.

Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0027] Unless otherwise specified, all technical and scientific terms used herein have the standard meanings in the art to which the claimed subject matter belongs. If there are multiple definitions for a term, the definition herein shall prevail.

[0028] Changing into specialized sportswear or yoga clothes every time you exercise is cumbersome. Most people prefer casual wear for light exercise anytime, anywhere. Stretch denim is a great option for this. However, current elastic yarns are not durable enough, limiting the development of stretch denim in the casual sports arena.

[0029] For the above questions, refer to Figure 1 、 Figure 2 and Figure 3 An embodiment of the present application provides a new type of elastic core-spun yarn, including a yarn core 1 and a covering layer wrapped around the yarn core 1, the covering layer including a vinylon layer 2 directly covering the yarn core 1 and a braided yarn layer 3 wrapped around the vinylon layer 2, the braided yarn layer 3 including bamboo fiber yarn 31 and cotton fiber yarn 32, the bamboo fiber yarn 31 and the cotton fiber yarn 32 are overlapped and woven into a tubular braided yarn layer 3 that covers the vinylon layer 2.

[0030] When the entire yarn is stretched, due to the instability of the quadrilateral, the braided yarn layer will be deformed, and the two yarns at the braiding point will also rub against each other. These frictions and deformations have the effect of absorbing energy, which can reduce the load on the yarn core 1 when the entire yarn is stretched, and avoid the problem of the yarn core 1 losing elasticity due to multiple over-stretching. It is beneficial to improve the elasticity and stretchability of the elastic core-spun yarn and increase its service life.

[0031] The braided yarn layer 3 includes a total of 12 bamboo fiber yarns 31 and cotton fiber yarns 32. The bamboo fiber yarns 31 and cotton fiber yarns 32 have good moisture absorption and air permeability, which is conducive to moisture absorption and perspiration. Figure 3 ( Figure 3 In order to show the clear weaving structure, the yarn core and the vinylon layer are not drawn). As shown in the figure, after the two yarns are woven into this application, there are certain meshes instead of dense coverage, which is more conducive to moisture absorption and perspiration.

[0032] In addition, after washing with hot water, the vinylon layer 2 will completely or partially dissolve, leaving gaps between the braided yarn layer and the yarn core, such as Figure 2 The structure of the yarn after the vinylon layer 2 is dissolved is shown. When exercising while wearing fabric containing the yarn core, the gaps left by the vinylon layer cooperate with the fibers and mesh of the woven yarn core layer, which further facilitates the transmission of sweat and air and reduces the stuffy feeling caused by sweating during exercise.

[0033] Reference Figure 3One of the bamboo fiber yarn 31 and the cotton fiber yarn 32 is spiraled clockwise around the vinylon layer 2, and the other is spiraled counterclockwise around the vinylon layer 2, but this is not a simple S-twist wrapping and Z-twist wrapping. There is a relationship of alternating overlap between the two, thereby exerting the effects of quadrilateral deformation and weaving point friction.

[0034] Preferably, the braided yarn layer 3 is woven from six bamboo fiber yarns 31 and six cotton fiber yarns 32. This is equivalent to the braided yarn layer being woven from two groups of yarns with different spin directions: one group consisting of bamboo fiber yarns 31 and the other of cotton fiber yarns 32, with six yarns in each group. The bamboo fiber yarns 31 provide a certain degree of antibacterial properties and a soft touch required for exercise, while the cotton fiber yarns 32 offer wear resistance, which helps increase the elasticity required for the entire yarn core.

[0035] The yarn core 1 can be a T400 fiber with a denier of 70D to 150D, which can avoid a large difference in elasticity between the yarn core and the braided yarn layer, prevent the yarn from being too loose or too tight as a whole and causing kinks, and is conducive to ensuring yarn quality. Preferably, the yarn core 1 is a 100D T400 fiber.

[0036] Specifically, the count of the bamboo fiber yarn 31 is 16S, and the count of the cotton fiber yarn 32 is 16S. The bamboo fiber yarn 31 and the cotton fiber yarn 32 are relatively thin, which is conducive to having enough space to deform the braided yarn layer 3 when the entire yarn is stretched, but they cannot be too thin, otherwise the braided yarn layer 3 is at risk of breaking when the entire yarn is stretched.

[0037] Combined with the preferred specifications of the above-mentioned core yarn 1, bamboo fiber yarn 31 and cotton fiber yarn 32, the count of the whole new elastic core-spun yarn is 7S.

[0038] In addition, embodiments of the present application further provide a fabric comprising the novel elastic core-spun yarn described above. If fabricated into denim fabric, the fabric may be woven, comprising interwoven warp and weft yarns in a three-up, one-down arrangement, with the weft being the novel elastic core-spun yarn and the warp being indigo or sulfur black dyed cotton yarn.

In this specification, illustrative uses of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
