AI Technical Summary
Due to the fibrillation properties in the wet state, Lycel fibers will cause itchy when the yarn comes into contact with the skin, and it will be difficult to have good anti-pilling properties.
The anti-pilling vortex spinning yarn is made by vortex spinning method, including high-strength viscose fiber filaments, anti-bacterial fiber layers, anti-pilling core yarn, ES filaments and cotton fibers or viscose fibers. Through the combination of these layers and heat treatment, the wool pilling phenomenon is reduced and the anti-bacterial properties of the yarn are improved.
The yarn has a good anti-pilling effect, while avoiding itchy problems, and improving the health of the fabric through an antibacterial fiber layer.

Abstract
Description
Technical Field
[0001] The utility model relates to an anti-pilling vortex-spun lyocell yarn, belonging to the technical field of vortex-spun yarns. Background Art
[0002] Lyocell fiber is made of pulp formed by crushing renewable bamboo and wood, and the recovery rate of the solvent used in the preparation process is as high as 99.7%, which is not only energy-saving and environmentally friendly, but also sustainable. Lyocell fiber has the advantages of cotton comfort and polyester strength. However, due to its unique fibrillation characteristics, Lyocell fiber will split fibrils along the axial direction of the fiber through friction in a wet state, which will make it feel itchy when in contact with the skin. How to utilize the strength of Lyocell fiber and make the prepared Lyocell yarn not feel itchy and have good anti-pilling performance has become a problem to be solved. Utility Model Content
[0003] The utility model aims to provide an anti-pilling vortex-spun lyocell yarn, which has a good anti-pilling effect.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:
[0005] The utility model relates to an anti-pilling vortex-spun lyocell yarn, comprising a core yarn, a first coating layer and a first wrapping layer; the core yarn is a high-strength viscose fiber filament, and the first coating layer is vortex-spun from an antibacterial fiber layer; the first wrapping layer comprises an anti-pilling core yarn, a strand formed by the parallel-twisted lyocell filaments and ES filaments, and cotton fiber or viscose fiber wrapped around the outside of the strand; the antibacterial fiber used in the antibacterial fiber layer is a lyocell fiber with nano zinc oxide particles attached to the surface.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the first wrapping layer also includes polylactic acid filaments, and the cross-section of the polylactic acid filaments is Y-shaped or cross-shaped.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the polylactic acid filaments and the anti-pilling core-spun yarn are spirally arranged in opposite directions.
[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: a second coating layer is arranged between the first coating layer and the first wrapping layer; the second coating layer is an anti-ultraviolet fiber layer.
[0009] On the basis of the above solution and as a preferred solution of the above solution: the first wrapping layer also includes an antistatic yarn.
[0010] The beneficial effects of the utility model are as follows: the anti-pilling vortex-spun lyocell yarn involved in the utility model uses strong viscose fiber filaments and lyocell filaments to provide good strength for the yarn, and because the ES filaments used are heat-treated, they will be bonded to adjacent fibers or filaments, thereby reducing the occurrence of pilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a schematic structural diagram of the anti-pilling vortex-spun lyocell yarn involved in the second embodiment.
[0013] The markings in the figure are as follows: 1-core yarn; 2-first covering layer; 3-first wrapping layer; 4-second covering layer; 31-anti-pilling core yarn; 32-polylactic acid filament; 33-antistatic yarn. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] Embodiment 1
[0016] Combination Figure 1 , this embodiment is described in detail. The anti-pilling vortex-spun lyocell yarn involved in this embodiment comprises a core yarn 1, a first coating layer 2 and a first wrapping layer 3; the core yarn is a high-strength viscose fiber filament, and the first coating layer 2 is vortex-spun by an antibacterial fiber layer; the first wrapping layer 3 comprises an anti-pilling core yarn 31, a strand formed by the parallel-twisted lyocell filaments and ES filaments, and cotton fiber or viscose fiber wrapped on the outside of the strand; the antibacterial fiber used in the antibacterial fiber layer is a lyocell fiber with nano zinc oxide particles attached to the surface.
[0017] The high-strength viscose fiber filaments used can provide higher strength for the spinning. And the lyocell filaments are located inside the anti-pilling core-spun yarn 31, and the problem of surface fibrillation will not affect the user. And the ES filaments twisted with the lyocell filaments can be bonded with adjacent fibers or filaments because the ES filaments will melt when heated, thereby reducing the problem of pilling. In this embodiment, the cotton fiber is coated on the outside of the anti-pilling core-spun yarn 31. After the yarn is heat-treated, the cotton fiber will bond with the ES filaments, thereby reducing the number of cotton fibers in a floating state, thereby reducing the occurrence of pilling.
[0018] The lyocell fiber with nano zinc oxide particles attached to the surface has a good antibacterial effect, so that the fabric clothing prepared from the yarn becomes a line of defense to protect human health and reduce the growth of bacteria.
[0019] Furthermore, the first wrapping layer 3 further comprises polylactic acid filaments 32, and the cross section of the polylactic acid filaments 32 is Y-shaped or cross-shaped. The polylactic acid filaments 32 and the anti-pilling core-spun yarn 31 are spirally arranged in opposite directions. In this embodiment, the cross section of the polylactic acid filaments 32 is Y-shaped, and grooves can be formed on its surface to have a moisture-conducting effect.
[0020] The anti-pilling vortex-spun lyocell yarn involved in this embodiment is woven in a plain weave to form a fabric, and its anti-pilling grade reaches level 4 after testing.
[0021] Embodiment 2
[0022] Combination Figure 2 , this embodiment is described in detail. The anti-pilling vortex spun lyocell yarn involved in this embodiment is different from that in the first embodiment in that a second coating layer 4 is provided between the first coating layer 2 and the first wrapping layer 3; the second coating layer 4 is an anti-ultraviolet fiber layer, so that the fabric prepared by the yarn has an anti-ultraviolet effect. Another difference from the first embodiment is that the first wrapping layer 3 also includes an antistatic yarn 33.
