[0002] As a necessity in daily life, clothing is the focus of people's attention in terms of functionality and decoration. As the proportion of knitted clothing in the entire clothing market increases year by year, finding more interesting and practical design methods has become a problem faced by more and more knitting practitioners.

[0003] The existing yarn has a single color, and the fabrics made from it and the colors thereof are relatively monotonous.

[0004] Prior art, patent document CN202121950077.7 discloses a multi-color gradient yarn, which is surrounded by a color yarn with color blocks on the outer wall of the color-changing yarn body. Although the fabric made of the obtained yarn has a full color, it solves the problem of monotonous color on the current yarn. The yarn obtained by this scheme belongs to segment dyeing yarn, which is to dye the yarn in sections and dye it with more than two colors. The usual dyeing techniques are skein segment dyeing and segment segment dyeing. The former places the skein in the yarn trough, sets the position of several dye liquid nozzles, and sprays the dye liquid to the predetermined position to make the yarn present different colors. The latter is also called the warp segment dyeing method, which places several yarns on a fixed track and dyes the fixed yarn by spraying the dye liquid. In summary, the colored yarn is provided with different color blocks along its axial direction, and it is also difficult to achieve large-area color changes.

Detailed implementation manners

[0030] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0031] "Outer surface", "surface layer", "inner", "outer" are referenced based on the normal use state of the gradient fancy yarn, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0032] In addition, terms such as "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0033] As Figures 1 - 5 shown, the gradient fancy yarn disclosed by the present utility model includes a core yarn 1 and a color yarn 2. Among them, the core yarn 1 contains a reinforcing yarn 11 and a moisture-absorbing yarn 12; the color yarn 2 is arranged on the outer surface of the core yarn 1 and includes unit colored yarns 20 arranged along the circumferential direction of the core yarn 1. Specifically, the unit colored yarns are wound around the outer surface of the core yarn in the same twist and side-by-side wrapping manner, and adjacent unit colored yarns show sequential gradient colors. The moisture-absorbing yarn 12 is wrapped around the outer surface of the reinforcing yarn 11.

[0034] The core yarn 1 composed of the reinforcing yarn 11 and the hygroscopic yarn 12 improves the strength, durability, hygroscopicity and breathability of the fancy yarn, expands the application scenarios, and improves the comfort and service life. The unit colored yarns 20 arranged along the circumference of the core yarn 1 use dyes of adjacent colors to dye each yarn one by one into colored yarns of the same series with different colors, so as to obtain unit colored yarns 20 with sequential gradient colors. That is, the same yarn only needs to be dyed with one color, and then the unit colored yarns 20 are arranged in sequential gradient colors, and are wrapped around the outer surface of the core yarn 1 in the same twist and side-by-side twisting and wrapping manner along the circumference of the core yarn 1.

[0035] The outer surface of the reinforcing yarn 11 has a groove 10 extending in the axial direction. The arrangement of the groove 10 enables the fiber to have good air permeability gaps and channels, improves the moisture permeability, and also greatly increases the fiber specific surface area, and can attach functional surface layers, such as antibacterial surface layers, anti-ultraviolet surface layers, etc.

[0036] In some embodiments, the reinforcing yarn 11 is polyester fiber; the hygroscopic yarn 12 is nylon, natural fiber or regenerated cellulose fiber; one of the adjacent unit colored yarns 20 is modal fiber 21, and the other is antistatic fiber yarn 22. In order to optimize the antibacterial properties of the fancy yarn and optimize the sustainability of the antibacterial properties, the outer surface of the hygroscopic yarn 12 in the core yarn 1 is provided with an antibacterial surface layer 120, and the antibacterial surface layer 120 is a chitosan attachment layer and / or a silver-containing attachment layer.

[0037] Among them, the attachment layer adopts a coating method, and the coating methods include dipping, spraying and padding; the fiber can be directly immersed in a chitosan solution or a silver-containing solution, and then dried and solidified. The chitosan solution or the silver-containing solution is evenly sprayed on the fiber surface by spraying. The fiber is passed through a padding device to make the chitosan solution or the silver-containing solution evenly attached to the fiber. The coating components include an antibacterial agent, a cross-linking agent, a surfactant and a compound antibacterial agent. The cross-linking agent is used to enhance the stability and durability of the coating. The cross-linking agent can improve the dispersibility of the antibacterial agent and the binding force with the fiber. The compound antibacterial agent can synergize with the antibacterial agent to improve the antibacterial effect.

[0038] Nylon (nylon) Nylon has a high tensile strength and can withstand large external forces, making the nylon layer suitable for applications that require high mechanical strength. It has good wear resistance and is not easy to wear, making it suitable for making products that require durability. It has good resistance to most chemicals and can be used in a variety of chemical environments and is not easily corroded. Compared with other synthetic fibers, the nylon layer has good hygroscopicity and absorbs a certain amount of moisture, which helps to maintain the comfort of the wearer. It has a certain heat resistance and can be used within a certain temperature range, but it cannot be used at high temperatures otherwise it will deform. It has good flexibility and can be easily bent without breaking easily.

[0039] Natural fibers include wool, hemp fibers (such as linen, ramie, etc.), silk fibers, and cotton fibers. Regenerated cellulose fibers include modal fibers and tencel fibers. Modal fibers have a very soft handfeel and good hygroscopicity, optimizing the comfort of fancy yarns whether as hygroscopic yarns or single-color yarns.

[0040] In some embodiments, the reinforcing yarn 11 is a polyester fiber filament; the hygroscopic yarn 12 is nylon, a natural fiber, or a regenerated cellulose fiber; one of the adjacent single-color yarns 20 is a modal fiber 21, and the other is an antistatic fiber yarn 22. To optimize the antibacterial property of the fancy yarn and the persistence of antibacterial effect, the hygroscopic yarn 12 in the core yarn 1 is an inner antibacterial fiber yarn. The inner antibacterial fiber yarn is nylon, a natural fiber, or a regenerated cellulose fiber containing silver and / or copper ions. Further, the antistatic fiber yarn 22 is a carbon-containing cotton fiber yarn, a carbon-containing hemp fiber yarn, a metal-containing cotton fiber yarn, or a metal-containing hemp fiber yarn. The setting of the antistatic fiber yarn 22 improves the wearing comfort. The polyester-containing reinforcing yarn has the phenomenon of generating static electricity. However, static electricity will cause an adsorption phenomenon between the clothes and the skin, making people feel uncomfortable; the generation of static electricity will also attract dust and particles in the air, making the clothes easy to be contaminated with dust and difficult to keep clean; in addition, static electricity may affect the appearance of the clothes, causing the fabric to wrinkle or deform, etc.

[0041] In some embodiments, the reinforcing yarn 11 is a carbon fiber filament, and the hygroscopic yarn 12 is nylon, a natural fiber, or a regenerated cellulose fiber; one of the adjacent single-color yarns 20 is a modal fiber 21, and the other is an outer antibacterial fiber yarn 23.

[0042] In some embodiments, the reinforcing yarn 11 is a carbon fiber filament 100 and a polyester fiber filament 101. With the carbon fiber filament 100 as the core, the polyester fiber filament 101 is disposed around the circumference of the carbon fiber filament 100 and combined by adhesion or hot pressing. The hygroscopic yarn 12 is nylon, a natural fiber, or a regenerated cellulose fiber; one of the adjacent single-color yarns 20 is a modal fiber 21, and the other is an outer antibacterial fiber yarn 23. The outer antibacterial fiber yarn 23 is a bamboo fiber yarn, a chitosan fiber, a kapok fiber, a silver-containing hemp fiber yarn, a silver-containing cotton fiber yarn, a copper-containing hemp fiber yarn, or a copper-containing cotton fiber yarn. Further, the outer antibacterial fiber yarn 23 is a bamboo fiber yarn, a chitosan fiber, a silver-containing hemp fiber yarn, or a silver-containing cotton fiber yarn. Among them, the bamboo fiber yarn has antibacterial property, hygroscopicity and air permeability, soft comfort, and antistatic performance; the silver-containing weft yarn has a better antibacterial effect compared to the silver-containing weft yarn.
