Description

Technical Field

[0001] This utility model belongs to the field of textile materials technology, and in particular relates to a tensile and abrasion-resistant ultra-long polyester-viscose yarn with white residue. Background Technology

[0002] Yarn is a fundamental material in the textile industry, and its performance directly affects the quality of fabrics. Traditional polyester-viscose yarns are mostly made from blends of ordinary polyester fibers and viscose fibers. Although they have a certain strength and abrasion resistance, they still have problems such as insufficient tensile strength and easy pilling, making it difficult to meet the needs of some fabrics. Therefore, we propose a tensile and abrasion resistant ultra-long polyester-viscose yarn with white residue. Utility Model Content

[0003] To address the problems existing in the above-mentioned technologies, this utility model provides a tensile and abrasion-resistant ultra-long polyester-viscose white yarn, which solves the problems of insufficient tensile strength and easy pilling of ultra-long polyester-viscose white yarn.

[0004] This invention is achieved as follows: a tensile and abrasion-resistant ultra-long polyester-viscose yarn with white coating includes a core layer and an outer covering layer spirally wrapped around the core layer. Both the core layer and the outer covering layer are made of ultra-long polyester fibers and viscose fibers. The outer covering layer is combined with the core layer through a twisting process. The outer wall of the outer covering layer is also provided with a functional coating.

[0005] As a preferred embodiment of the present invention, the core layer comprises multiple strands of wire, which are bonded together by a twisting process.

[0006] As a preferred embodiment of this invention, the surface of the wire core is provided with a microporous structure, the pore size of which is 5-20μm and the porosity is ≥40%.

[0007] As a preferred embodiment of this invention, the ultra-long polyester fiber is a high-strength, low-elongation polyester fiber.

[0008] As a preferred embodiment of this invention, the viscose fiber is a high wet modulus viscose fiber.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention uses a core layer formed by bonding multiple strands of yarn together to improve the tensile strength and abrasion resistance of the core layer, thereby increasing the service life of the yarn. The core layer is spirally connected to an outer sheath layer, which further improves the abrasion resistance of the yarn. The outer wall of the outer sheath layer is provided with an optional functional coating, which further expands the application range of the yarn. Attached Figure Description

[0014] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] Example 1:

[0017] like Figures 1 to 2 As shown in the figure, this utility model provides a tensile and abrasion-resistant ultra-long polyester-viscose yarn with white coating, including a core layer 1 and an outer covering layer 2 spirally wrapped around the core layer 1. Both the core layer 1 and the outer covering layer 2 are made of ultra-long polyester fibers and viscose fibers blended together. The outer covering layer 2 is combined with the core layer 1 through a twisting process. The outer wall of the outer covering layer 2 is also provided with a functional coating. This utility model uses multiple strands of yarn core 21 bonded together to form the core layer 1, which improves the tensile and abrasion resistance of the core layer 1, thereby increasing the service life of the yarn. The outer covering layer 2 is spirally connected to the outside of the core layer 1, which further improves the abrasion resistance of the yarn. The optional functional coating on the outer wall of the outer covering layer 2 further expands the application range of the yarn.

[0018] like Figure 1 As shown, the core layer 1 includes multiple strands of yarn core 21, which are bonded together by a twisting process. The surface of each yarn core 21 has a microporous structure 22 with a pore size of 5-20 μm and a porosity ≥40%. The extra-long polyester fiber is a high-strength, low-elongation polyester fiber; the viscose fiber is a high-wet-modulus viscose fiber. Both the yarn core 21 and the outer covering layer 2 of this invention are twisted from high-strength, low-elongation polyester fiber and high-wet-modulus viscose fiber, further improving the tensile strength, dimensional stability, and wrinkle resistance of the yarn. Furthermore, the microporous structure 22 on the yarn core 21 enhances the breathability of the yarn.

[0019] Working principle of Example 1:

[0020] In use, the core layer 1 is formed by bonding multiple strands of yarn core 21 together, which improves the tensile strength and abrasion resistance of the core layer 1. The core layer 1 is spirally connected to the outside of the outer sheath layer 2, which further improves the abrasion resistance of the yarn and prevents the yarn from breaking when stretched or subjected to friction, thereby increasing the service life of the yarn. In addition, the outer wall of the outer sheath layer 2 has an optional functional coating, which further expands the application range of the yarn.
