Description

Technical Field

[0001] This utility model relates to a flax yarn, specifically an antibacterial and wear-resistant flax yarn. Background Technology

[0002] Linen yarn, spun from flax fibers, possesses advantages such as strong moisture absorption, rapid heat dissipation, good breathability, and good antistatic properties, making it widely used in clothing fabrics and other fields. However, it also has some drawbacks. Linen yarn has poor abrasion resistance and is prone to wear and tear during daily use, affecting its lifespan. With the improvement of people's living standards, the requirements for the quality and performance of textiles are becoming increasingly higher. Consumers not only expect clothing made from linen yarn to provide a comfortable wearing experience but also desire good antibacterial properties to effectively inhibit bacterial growth, reduce odor, and protect human health. Simultaneously, for linen products that require frequent use, such as home decor fabrics and bedding, people also desire greater durability and resistance to damage. Therefore, this application provides an antibacterial and abrasion-resistant linen yarn. Utility Model Content

[0003] The purpose of this invention is to provide an antibacterial and abrasion-resistant linen yarn, which is designed to have better abrasion resistance and antibacterial properties compared to pure linen yarn.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: an antibacterial and wear-resistant linen yarn, comprising: a yarn body, the yarn body including a first yarn, a second yarn, a third yarn and a fourth yarn, the second yarn being spirally wound around the outside of the first yarn to form a first core yarn, the first core yarn and the third yarn being arranged side by side as a second core yarn, and the fourth yarn being spirally wound around the outside of the second core yarn to form the yarn body; the first yarn is linen yarn; the third yarn is antibacterial yarn; the second yarn and the fourth yarn are both wear-resistant yarns.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the wrapping twist direction of the second yarn is S twist, and the wrapping twist direction of the fourth yarn is Z twist.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the flax yarn is antibacterial flax yarn.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial yarn is nano zinc oxide modified nylon 6 filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant yarn is a bio-based nylon filament.

[0009] The beneficial effects of this utility model are as follows: Based on the antibacterial and wear-resistant linen yarn of this utility model, the second and fourth yarns are wrapped in different twist directions to form a partial mesh-like wrapping structure on the outside of the yarn, which significantly enhances the stability of the yarn structure, effectively reduces the wear of the core yarn caused by external friction, and greatly improves the wear resistance of the yarn. Moreover, both the second and fourth yarns are wear-resistant yarns, which further improves the wear resistance of the yarn body. The third yarn is made of antibacterial yarn, which has excellent antibacterial effect, helps to improve the antibacterial performance of the yarn body, and can effectively inhibit the growth of a variety of common harmful bacteria. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of the antibacterial and abrasion-resistant flax yarn involved in this utility model; In the diagram: 1 - first yarn, 2 - second yarn, 3 - third yarn, 4 - fourth yarn. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] Combination Figure 1 This embodiment provides a detailed description of an antibacterial and abrasion-resistant linen yarn, comprising: a yarn body, the yarn body including a first yarn 1, a second yarn 2, a third yarn 3, and a fourth yarn 4, wherein the second yarn 2 is spirally wound around the outside of the first yarn 1 to form a first core yarn, the first core yarn and the third yarn 3 are arranged side by side as a second core yarn, and the fourth yarn 4 is spirally wound around the outside of the second core yarn to form the yarn body; the first yarn 1 is linen yarn; the third yarn 3 is antibacterial yarn; and the second yarn 2 and the fourth yarn 4 are both abrasion-resistant yarns.

[0013] Furthermore, the second yarn 2 has an S-twist, and the fourth yarn 4 has a Z-twist. The second yarn 2 and the fourth yarn 4 together form a partial mesh wrapping structure on the outside of the yarn body, which enhances the structural stability of the yarn to a certain extent, effectively reduces the wear of the core yarn caused by external friction, and greatly helps to improve the abrasion resistance of the yarn and the woven fabric.

[0014] Specifically, the yarn body is made by combining four yarns with two sets of hollow spindles. The first yarn 1 is wrapped by the second yarn 2 through the first set of hollow spindles to form the first core yarn, which is then combined with the third yarn 3 and enters the second set of hollow spindles, and is then wrapped by the fourth yarn 4 to form the yarn body.

[0015] Furthermore, the flax yarn is antibacterial flax yarn. The antibacterial flax yarn is obtained by impregnating and modifying flax yarn with a lavender / dandelion compound extract. Specifically, the flax yarn is first modified by alkali boiling, with the following modification parameters: NaOH mass concentration 4.0 g / L, NaCO3 mass concentration 2.5 g / L, CH4N2O mass concentration 2.0 g / L, JFC mass concentration 1.0 g / L, treatment temperature 90℃, treatment time 60 min, and liquor ratio 1:10. The modified flax yarn is then impregnated in a lavender / dandelion compound extract with a lavender extract concentration of 15 g / L and a dandelion extract concentration of 25 g / L, at a treatment temperature of 20℃ for 5 h. The resulting antibacterial flax yarn exhibits inhibition rates of 99.82% and 99.89% against Staphylococcus aureus and Escherichia coli, respectively, demonstrating excellent antibacterial effects.

[0016] Furthermore, the antibacterial yarn is nano-zinc oxide modified nylon 6 filament. Nano-zinc oxide modified nylon 6 filament is produced using the masterbatch method in blend spinning. The inorganic antibacterial agent nano-zinc oxide is added to nylon 6 chips, and an antibacterial masterbatch is prepared using a screw extruder. Then, the antibacterial masterbatch and nylon 6 chips are thoroughly mixed and fed into a hopper for melt spinning. Zinc oxide is a white inorganic antibacterial agent that releases antibacterial ions upon use, thereby giving the product antibacterial properties. Nano-zinc oxide is an inorganic nano-antibacterial agent; due to its nano-carrier structure, its specific surface area is increased, allowing for better adsorption of microorganisms, thus achieving a superior antibacterial effect compared to micron-sized nano-zinc oxide. Specifically, with a zinc oxide mass fraction of 5% and an antibacterial masterbatch addition of 5%, the resulting nano-zinc oxide modified nylon 6 filament exhibits an antibacterial rate of over 90% against Candida albicans, Escherichia coli, and Staphylococcus aureus. Furthermore, the addition of nano-zinc oxide has minimal impact on the mechanical properties of the nano-zinc oxide modified nylon 6 filament.

[0017] Furthermore, the wear-resistant yarn is a bio-based nylon filament. Bio-based nylon is a polyamide product produced by converting alkanes, bio-based alkanes, oil scraps, fatty acids, and biomass into pentanediamine through a bioprocess, followed by polymerization. Bio-based nylon exhibits better wear resistance than nylon 6, primarily because it possesses higher tensile strength and elongation, allowing it to store more tensile energy. During friction, the fibers are subjected to repeated stress; yarns with higher tensile strength and elongation can better withstand this stress, thus exhibiting superior wear resistance.

[0018] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
