Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to an anti-pilling vortex yarn and a preparation method and application thereof. Background Art

[0002] After being made into home textile products, pure cotton woven fabrics are constantly subjected to friction, rubbing, and bending during use and washing, causing pilling, which affects the appearance and performance of home textile products. As living standards improve, consumers are increasingly concerned about and demanding higher levels of anti-pilling performance, especially after washing. Existing pure cotton home textile fabrics are prone to pilling and have poor abrasion resistance. After repeated washing, their anti-pilling performance significantly decreases.

[0003] To address these issues, patent publication number CN109610173B utilizes an anti-pilling finishing liquid in combination with a process, resulting in excellent anti-pilling properties for the finished fabric. However, this method suffers from poor stability, with resistance significantly deteriorating after repeated washing. Patent publication number CN102168328B utilizes a jet vortex spinning method for home textile fabrics, but can only produce cotton yarn with a density below 30 Ne. The resulting fabric has a stiff feel and a blurred surface texture due to the lack of significant twist in the vortex-spun yarn. Patent publication number CN111778613A utilizes vortex-spun and compact-spun warp and weft yarns in a 1:1 and 2:2 ratio, respectively, with the vortex-spun yarn serving as the primary friction-bearing component to improve the anti-pilling properties of viscose fabrics. However, due to the greater shrinkage of vortex-spun yarns compared to compact-spun yarns, the fabric surface smoothness is poor after washing. Summary of the Invention

[0004] The present invention provides an anti-pilling vortex yarn and a preparation method and application thereof, which can improve the wear resistance of the yarn and increase the softness of the yarn, thereby improving the anti-pilling performance of home textile fabrics.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention provides a method for preparing anti-pilling vortex yarn, which comprises at least the following steps:

[0007] 6 to 8 long-staple cotton combed slivers are drawn together through a drawing process to obtain long-staple cotton combed slivers;

[0008] 6 to 8 fine-staple cotton combed slivers are drawn together through a drawing process to obtain fine-staple cotton combed slivers;

[0009] Drawing the long-staple cotton combed sliver and the fine-staple cotton combed sliver to produce a combed drawn sliver; wherein the long-staple cotton combed sliver accounts for 20-70% of the total basis weight of the combed drawn sliver, and the basis weight of the combed drawn sliver is 1.5-5.0 Ktex; and

[0010] The combed and drawn yarn is fed into a vortex spinning machine for spinning to obtain the vortex yarn, wherein the fine-staple cotton is located at the center of the vortex yarn and the long-staple cotton annularly wraps the fine-staple cotton.

[0011] In one embodiment of the present invention, the main fiber length of the long-staple cotton combed sliver is 33-41 mm, and the basis weight of the long-staple cotton combed sliver is 2.0-6.0 Ktex.

[0012] In one embodiment of the present invention, the main fiber length of the fine-staple cotton combed sliver is 28-32 mm, and the basis weight of the fine-staple cotton combed sliver is 2.0-6.0 Ktex.

[0013] In one embodiment of the present invention, in the step of preparing the combed and drawn sliver, the total number of the long-staple cotton combed sliver and the fine-staple cotton combed sliver is 4 to 8.

[0014] In one embodiment of the present invention, in the step of preparing the combed drawn sliver, the total drafting ratio is 4 to 10 times, and the drafting ratio in the post-drafting zone is 1.1 to 1.5 times.

[0018] The present invention also provides an anti-pilling vortex yarn, which is prepared by the above-mentioned preparation method of the anti-pilling vortex yarn.

[0019] The present invention also provides a home textile fabric comprising the above-mentioned anti-pilling vortex yarn.

[0020] In summary, the present invention proposes a pilling-resistant vortex yarn, its preparation method, and its application, which can improve the wear resistance and strength of the yarn while increasing its softness. Fabrics made from this vortex yarn have improved softness and pilling resistance, thereby enhancing the quality and aesthetics of home textiles and improving the customer experience.

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] It should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided to make the disclosure thorough and complete and to fully convey the scope of the present invention to those skilled in the art. Unless otherwise specified, "%" and "parts" shown in the following examples refer to "mass %" and "mass parts" respectively.

[0029] The technical solution of the present invention is further described in detail below with reference to several embodiments and accompanying drawings. It is apparent that the embodiments described are only some, not all, of the embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0030] Vortex-spun yarn is made by twisting uniform cotton slivers through ultra-high drafting and vortex nozzles. Vortex yarn is notable for its low hairiness, resistance to pilling, and smooth surface finish. Yarns of the same raw material and yarn count produced by other spinning methods are thicker in diameter than yarns of the same yarn count. Its unique core-spun structure allows it to absorb moisture and dry quickly, making it widely used in various knitted garments. This invention proposes an anti-pilling vortex yarn, its preparation method, and its application. These yarns can reduce pilling after washing and are suitable for use in home textile fabrics.

[0031] See also Figures 1 to 3 As shown, the present invention also provides a method for preparing anti-pilling vortex yarn, including but not limited to the following steps S100-S400.

[0032] Step S100, preparing long-staple cotton combed sliver: 6 to 8 long-staple cotton combed slivers are subjected to a drawing process for drawing and drafting to obtain long-staple cotton combed sliver.

[0033] Step S200, preparing fine-staple cotton combed sliver: 6 to 8 fine-staple cotton combed slivers are subjected to a drawing process for drawing and drafting to obtain fine-staple cotton combed slivers.

[0034] Step S300, preparation of combed drawn sliver: long-staple cotton combed sliver and fine-staple cotton combed sliver are drawn to prepare combed drawn sliver; wherein the long-staple cotton combed sliver accounts for 20-70% of the total basis weight of the combed drawn sliver, and the basis weight of the combed drawn sliver is 1.5-5.0 Ktex.

[0035] Step S400, preparation of vortex yarn: feeding the combed and drawn yarn into a vortex spinning machine for spinning to obtain vortex yarn with anti-pilling properties, wherein the fine-staple cotton is located at the center of the vortex yarn and the long-staple cotton is annularly wrapped around the fine-staple cotton.

[0036] See also Figure 1As shown, in step S100, in one embodiment of the present invention, long-staple cotton raw cotton is first made into long-staple cotton combed sliver, which is then made into long-staple cotton combed sliver. Specifically, 100% long-staple cotton raw cotton is sequentially subjected to the following processes: cotton blending, cotton opening and cleaning, cotton combing, pre-combing preparation, and combing to produce long-staple cotton combed sliver. The long-staple cotton combed sliver is then drawn to obtain long-staple cotton combed sliver. In one embodiment of the present invention, the basis weight of the long-staple cotton combed sliver is controlled, for example, within a range of 2.0 to 6.0 ktex, and further, within a range of 2.5 to 4.0 ktex. The combing noil rate is adjusted based on the cotton blending conditions, thereby controlling the main fiber length of the long-staple cotton combed sliver to, for example, 33 to 41 mm, and further, within a range of 35 to 38 mm. In one embodiment of the present invention, for example, 6 to 8 long-staple cotton combed slivers are drawn and combined to produce long-staple cotton combed sliver, and the basis weight of the long-staple cotton combed sliver is controlled to be, for example, 2.0 to 6.0 ktex, and further, the basis weight of the long-staple cotton combed sliver is controlled to be, for example, 2.5 to 4.0 ktex.

[0037] See also Figure 1 As shown, in step S200, in one embodiment of the present invention, for example, fine-staple cotton raw cotton is first formed into fine-staple cotton combed sliver, which is then formed into fine-staple cotton combed sliver. Specifically, 100% fine-staple cotton raw cotton is sequentially subjected to steps such as cotton blending, cotton opening and cleaning, combing, pre-combing preparation, and combing to form fine-staple cotton combed sliver. The combed fine-staple cotton sliver is then drawn to obtain long-staple cotton combed sliver. In one embodiment of the present invention, the basis weight of the fine-staple cotton combed sliver is controlled, for example, to be between 2.0 and 6.0 ktex. Furthermore, the basis weight of the fine-staple cotton combed sliver is controlled, for example, to be between 2.5 and 4.0 ktex. The combing noil rate is adjusted based on the cotton blending conditions, thereby controlling the main fiber length of the fine-staple cotton combed sliver to be, for example, between 28 and 32 mm.

[0038] See also Figure 1As shown, the present invention does not limit the order of step S100 and step S200. Step S100 and step S200 can be performed step by step, or step S100 and step S200 can be performed simultaneously.

[0039] See also Figures 1 to 3 As shown, in step S300, in one embodiment of the present invention, the draw frame uses, for example, a roller drafting draw frame, and the rear roller group in the drafting zone includes rollers 30 and pressure rollers 40. The combed sliver fed into the draw frame is arranged between rollers 30 and pressure rollers 40, and the total number of combed slivers fed into the draw frame is, for example, 4 to 8 slivers, i.e., the total number of long-staple cotton combed slivers and fine-staple cotton combed slivers fed into the draw frame is 4 to 8 slivers. The long-staple cotton combed slivers account for 20 to 70% of the total basis weight of the fed combed slivers, and further, the long-staple cotton combed slivers account for 30 to 50% of the total basis weight of the fed combed slivers. In one embodiment of the present invention, the total draft ratio of the draw frame is, for example, 4 to 10 times, and the draft ratio in the rear drafting zone is, for example, 1.1 to 1.5 times. Furthermore, the total drafting ratio of the drawing frame is set to, for example, 6 to 8 times, and the drafting ratio of the rear drafting zone is set to, for example, 1.15 to 1.3.

[0040] See also Figure 1 As shown, in step S300, in this embodiment, for example, a "bucket"-type cotton web bundler is used in conjunction with a drawing frame to prepare a combed draw frame. Specifically, long-staple cotton combed sliver and fine-staple cotton combed sliver are fed into the drawing frame, with the long-staple cotton combed sliver accounting for 20-70% of the total basis weight of the fed combed sliver. The long-staple cotton combed sliver is arranged on the inner side, and the fine-staple cotton combed sliver is fed into the drawing frame in an arrangement where the long-staple cotton combed sliver surrounds the long-staple cotton combed sliver. After processing by the "bucket"-type cotton web bundler and the drawing frame, a combed draw frame is prepared, with the fine-staple cotton combed sliver moving to the inner side and the long-staple cotton combed sliver moving to the outer side. In one embodiment of the present invention, the basis weight of the prepared combed draw frame can be set to, for example, 1.5 to 5.0 ktex. Furthermore, the basis weight of the combed draw frame can be set to, for example, 2.5 to 4.0 ktex.

[0041] See also Figure 1 and Figure 2As shown, in one embodiment, long-staple cotton combed sliver 10 and fine-staple cotton combed sliver 20 are drawn together, with the long-staple cotton combed sliver 10 accounting for 50% of the total weight of the combed sliver and the fine-staple cotton combed sliver 20 accounting for 50% of the total weight of the combed sliver. Specifically, four long-staple cotton combed slivers 10 are arranged on the inner side, and four fine-staple cotton combed slivers 20 are symmetrically arranged on both sides of the long-staple cotton combed sliver 10. The long-staple cotton combed sliver 10 and the fine-staple cotton combed sliver 20 are placed between rollers 30 and press rollers 40, and processed through a "bucket"-type cotton web bundler (not shown), rollers 30, press rollers 40, etc., with the fine-staple cotton combed sliver 20 moving to the inner side and the long-staple cotton combed sliver 10 moving to the outer side.

[0042] See also Figure 1 and Figure 3 As shown, in another embodiment, long-staple cotton combed sliver 10 and fine-staple cotton combed sliver 20 are drawn together, with the long-staple cotton combed sliver 10 accounting for 30% of the total weight of the combed sliver and the fine-staple cotton combed sliver 20 accounting for 70% of the total weight of the combed sliver. Specifically, two long-staple cotton combed slivers 10 are positioned inside, four fine-staple cotton combed slivers 20 are symmetrically arranged on both sides of the long-staple cotton combed sliver 10, and two fine-staple cotton combed slivers 20 are positioned above the long-staple cotton combed sliver 10. The long-staple cotton combed sliver 10 and the fine-staple cotton combed sliver 20 are placed between rollers 30 and press rollers 40, and processed through a "bucket"-shaped cotton web bundler, rollers 30, press rollers 40, etc., with the fine-staple cotton combed sliver 20 moving inside and the long-staple cotton combed sliver 10 moving outside.

[0043] See also Figure 1 As shown, in step S400, in one embodiment of the present invention, after the combed and drawn yarn is prepared, the combed and drawn yarn is fed into a vortex spinning machine for spinning to produce vortex yarn. The negative pressure of the vortex spinning machine is reasonably set according to the percentage of the long-staple cotton fiber content to ensure that all the long-staple cotton fibers are spirally wrapped, while the fine-staple cotton fibers in the middle portion remain straight. In one embodiment of the present invention, the negative pressure of the vortex spinning machine is set to, for example, 5.6 to 6.0 bar, the draft ratio of the vortex spinning is set to, for example, 140 to 240 times, and the yarn delivery speed is set to, for example, 50 to 500 m / min. The long-staple cotton is arranged on the outside of the vortex yarn. The long-staple cotton fibers are relatively thick and long, have high fiber strength, and good wear resistance. The fine-staple cotton fibers are relatively thin, short, and soft. The fine-staple cotton is arranged in the center of the vortex yarn and the fine-staple cotton fibers are wrapped with the long-staple cotton fibers. This can improve the wear resistance of the yarn and increase the softness of the yarn.

[0044] In one embodiment of the present invention, the vortex yarn prepared by this method has a double-layer wrapping structure. Using this vortex yarn for household bedding fabrics can not only solve the pilling problem after multiple washings, but also improve the softness of the fabric and improve the quality of the bedding fabric.
