Description

Technical Field

[0001] This utility model relates to a wool yarn, specifically a mite-proof and moth-proof wool yarn. Background Technology

[0002] Wool is a natural protein fiber with advantages such as a soft luster, good elasticity, and strong moisture absorption and warmth retention, making it widely used in the textile industry. However, the natural protein composition of wool makes it susceptible to the growth of various bacteria, mites, and other microorganisms, and it is also prone to insect infestation.

[0003] As people's living standards improve, their demands for the quality and performance of wool products are also increasing. Consumers not only expect wool yarn to have good warmth and comfort, but also desire multiple functions such as mite resistance, insect resistance, and antibacterial properties to improve the lifespan and hygiene of wool products. Therefore, it is necessary to provide a mite- and insect-resistant wool yarn. Utility Model Content

[0004] The purpose of this invention is to provide a mite-proof and insect-proof wool yarn, which, compared with ordinary wool yarn, has multiple functions such as mite-proof, insect-proof, and antibacterial properties, thereby improving the service life and hygiene of wool products.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a mite-proof and moth-proof wool yarn, comprising: a yarn body, the yarn body including a core yarn and a wrapping yarn, the wrapping yarn being spirally wound around the outside of the core yarn; the core yarn including a first core yarn and a second core yarn, the first core yarn and the second core yarn being arranged side by side; the wrapping yarn including a first wrapping yarn and a second wrapping yarn, the first wrapping yarn and the second wrapping yarn having the same twist direction; the first core yarn being spandex filament; the second core yarn being elastic filament; the first wrapping yarn being a mite-proof yarn; and the second wrapping yarn being a moth-proof wool yarn.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the twist direction of both the first wrapping yarn and the second wrapping yarn is S twist.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic filament is CM800 bicomponent composite filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the anti-mite yarn is copper-modified antibacterial and anti-mite polyamide 6 fiber filament.

[0009] Based on the above scheme and as a preferred option: the insect-resistant wool yarn is a plant-based herbal antibacterial, moth-proof, and aromatic modified wool fiber yarn.

[0010] The beneficial effects of this utility model are as follows: Based on the anti-mite and anti-insect wool yarn of this utility model, the yarn adopts a double-core and double-wrap structure design, which imparts the anti-mite and anti-insect functions to different wrapping yarns respectively, so that the main body of the yarn can simultaneously achieve the functions of anti-mite and anti-insect. The core yarn adopts a parallel structure of spandex filament and elastic filament, which gives the yarn both stable elasticity and good stretchability and shape retention of the fabric, preventing the fabric from loosening and deforming after long-term use, while improving the comfort and fit when wearing.

[0012] In the diagram: 1-first core yarn, 2-second core yarn, 3-first wrapping yarn, 4-second wrapping yarn. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Combination Figure 1 This embodiment provides a detailed description of a mite-proof and moth-proof wool yarn, comprising: a yarn body, the yarn body including a core yarn and a wrapping yarn, the wrapping yarn being spirally wound around the outside of the core yarn; the core yarn including a first core yarn 1 and a second core yarn 2, the first core yarn 1 and the second core yarn 2 being arranged side by side; the wrapping yarn including a first wrapping yarn 3 and a second wrapping yarn 4, the first wrapping yarn 3 and the second wrapping yarn 4 having the same twist direction; the first core yarn 1 being spandex filament; the second core yarn 2 being elastic filament; the first wrapping yarn 3 being a mite-proof yarn; and the second wrapping yarn 4 being a moth-proof wool yarn.

[0015] Spandex molecular chains consist of soft and hard segments. The soft segments possess good flexibility and a low glass transition temperature, allowing them to bend and stretch freely at room temperature, providing spandex with its stretchable properties. The hard segments, on the other hand, have higher rigidity and cohesive energy. They are interconnected through intermolecular forces, forming physical cross-linking points. These cross-linking points limit excessive slippage of the molecular chains when spandex is stretched, and when the external force is removed, they promote the return of the molecular chains to their original positions, thus giving spandex excellent elastic recovery properties. Yarns made by wrapping non-elastic yarn around a spandex core possess both elasticity and the characteristics of the outer yarn or fiber, thus imparting elasticity to fabrics.

[0016] Furthermore, both the first wrapping yarn 3 and the second wrapping yarn 4 have an S-twist.

[0017] Specifically, the main body of the yarn is made by wrapping four yarns with two sets of hollow spindles. The most intuitive way of the composite is that two yarns are the outer wrapping yarns of the two sets of hollow spindles, namely the first wrapping yarn 3 and the second wrapping yarn 4. The other two yarns are used as the core yarns of the first set of hollow spindles and are wrapped twice to form a double-core double-wrap composite structure. When the two sets of hollow spindles are configured with the same twist direction, the radius and phase difference of the spiral of the outer wrapping yarn of the two sets of hollow spindles are different and fluctuate, which will produce a complex and varied winding structure. The yarn loops formed by the second wrapping may be embedded to varying degrees between the yarn loops formed by the first wrapping. This structure not only allows the yarn surface to present the functional effects of two types of wrapping yarn at the same time, but also enhances the cohesion of the yarn, reduces the occurrence of yarn slack and breakage during textile processing or use, and ensures the overall structural strength and processing applicability of the yarn.

[0018] Furthermore, the elastic filament is a CM800 bicomponent composite filament. The CM800 bicomponent composite filament is spun from two polymers with different heat shrinkage properties, PTT and PET, using composite spinning technology. Each component accounts for 50%. PTT and PET are both polyester materials, but they have different physical and thermal processing properties. The biggest feature of the CM800 bicomponent composite filament is that it utilizes the different thermal properties of the two components to obtain a three-dimensional crimped structure with staged natural crimp and fluffiness through composite spinning, resulting in durable and excellent elastic recovery performance.

[0019] Furthermore, the anti-mite yarn is a copper-modified antibacterial and anti-mite polyamide 6 fiber filament. The copper-modified antibacterial and anti-mite polyamide 6 fiber filament is obtained by coating spherical copper antibacterial agents with oleic acid as a modifier, then blending and granulating it with a polyamide 6 matrix to obtain copper-modified antibacterial and anti-mite polyamide 6 chips, which are then melt-spun. After 50 washes, the copper-modified antibacterial and anti-mite polyamide 6 fiber filament exhibits an inhibition rate of over 99% against Candida albicans, Staphylococcus aureus, and Escherichia coli. Its fabric achieves a mildew resistance rating of 0 and a mite repellency rate of 89%, demonstrating highly efficient and durable antibacterial, mildew-proof, and anti-mite properties.

[0020] Furthermore, the insect-resistant wool yarn is a plant-based antibacterial, moth-proof, and aromatic modified wool fiber yarn. This plant-based antibacterial, moth-proof, and aromatic modified wool fiber is obtained by pretreating the wool fiber with hydrogen peroxide and protease, and then using a composition of extracts from the plant-based herbs Forsythia suspensa, Sophora tonkinensis, pomegranate peel, and eucalyptus oil microcapsules to perform antibacterial, moth-proof, and aromatic modification treatments on the wool fiber. The plant-based antibacterial, moth-proof, and aromatic modified wool fiber exhibits antibacterial rates of 99.67% and 93.64% against Staphylococcus aureus and Escherichia coli, respectively. After 12 washes, the antibacterial rates remain at 92.92% and 82.02%, respectively. The moth-proof rating reaches 1B, and after 12 washes, it reaches 3B. It has a strong aromatic scent, with a fragrance retention rate of 28% after 9 washes and 8% after 12 washes.
