Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular to a wool yarn, a fabric and applications thereof. Background Art

[0002] As a natural protein fiber, wool is soft and elastic, providing users with a warm, skin-friendly touch. At the same time, its good air permeability and moisture absorption can adjust the humidity of various seat materials, keep the seat materials dry, and improve human comfort. In addition, because the materials made of wool fiber have a gorgeous appearance, natural luster and delicate texture, they can add a high-end and elegant atmosphere to clothing and seat materials, and can improve the quality of the product, so they are favored by the market.

[0003] However, pure wool fabrics made from single wool fibers now have weak cohesion between the wool fiber structures. Under the repeated action of external forces, the wool fibers will break due to wear. In addition, the wool fibers will generate heat during the friction process, causing the fibers to soften or even melt, thereby accelerating fiber wear, resulting in decreased strength and thinning of the fabrics made of wool yarn, and the appearance of breakage and poor wear resistance, making it impossible for wool fabrics to achieve a good balance between appearance, texture, service life and low cost.

[0004] Existing technology usually uses artificial fibers such as nylon and polyester filament to improve the wear resistance of yarn. However, although the blended wool fabric made by this method improves the wear resistance of yarn and fabric, it also destroys the delicate, skin-friendly and warm properties of wool. Its feel, breathability and humidity regulation are not as good as pure wool fabric. Summary of the invention

[0005] In order to overcome the above technical problems, the purpose of the present invention is to provide a wool yarn and its application. The present invention achieves a good balance in terms of wear resistance, softness and strength through a carefully designed specific fiber ratio and a semi-worsted spinning process, and significantly improves the wear resistance of pure wool fabrics. The yarn effectively solves the problem of insufficient wear resistance of existing wool yarns, avoids the phenomenon that wool fabrics are easily worn, thinned or even damaged during use, thereby extending the service life of the fabric. At the same time, the present invention retains the excellent characteristics of wool being delicate and soft, so that it can show excellent performance in different application scenarios.

[0006] It should be noted that the count mentioned in the present invention corresponds to the fineness of wool fibers. The diameter of the wool fibers represented by the count in the present invention is referenced to the national standard "Wool of Sheep" (GB1523 - 2013). The higher the count, the finer the wool, the smaller the fiber diameter, the more fiber roots in the cross-section of the yarn of the same count, and the better the uniformity and strength of the yarn. However, overly fine fibers are prone to entanglement and knotting during the spinning process, which will affect the quality of the yarn. During wearing, it is easy to cause pilling on the fabric surface.

[0007] The semi-worsted process mentioned in the present invention refers to an innovative spinning process that combines cotton spinning technology and wool spinning technology. This process is between worsted and woolen spinning. The front-end is a woolen blending machine plus cotton spinning carding, drawing, roving, and spinning machines, etc., and the back-end is worsted winding, doubling, and twisting equipment. Compared with the worsted wool spinning process, the semi-worsted process has a shorter production process, and the yarn produced is fluffier and softer than worsted wool spinning. Compared with the woolen spinning process, it has finer yarn count, even sliver, and smooth appearance.

[0008] The weight ratio in the present invention refers to the mass percentage of various wool fibers in the total fibers.

[0009] The first aspect of the present invention provides a wear-resistant wool yarn, which is mainly spun by combining first wool fibers, second wool fibers, and third wool fibers according to a weight ratio. Among them, the first wool fibers serve as the component providing a delicate surface texture, the second wool fibers serve as the main filling material, and the third wool fibers provide a skeleton support structure. The three cooperate to form a composite yarn structure with excellent wear resistance.

[0010] Preferably, the first wool fibers are wool fibers with a count of 90 and above, the second wool fibers are wool fibers with a count of 70 - 80, and the third wool fibers are wool fibers with a count of 66 and below.

[0011] Preferably, the first wool fibers are wool fibers with a count of 90, the second wool fibers are wool fibers with a count of 70 and / or 80, and the third wool fibers are wool fibers with a count of 60 - 66.

[0012] Preferably, the weight ratio of the first wool fibers is 5% - 15%, the weight ratio of the second wool fibers is 65% - 80%, and the weight ratio of the third wool fibers is 5% - 20%.

[0013] Preferably, the second wool fibers are any one or a combination of 70 and 80.

[0014] Preferably, the weight ratio of the first wool fibers is 8% - 12%, the weight ratio of the 80-count wool fibers in the wear-resistant wool yarn is greater than or equal to 60%, the weight ratio of the 70-count wool fibers in the wear-resistant wool yarn is greater than or equal to 10%, and the weight ratio of the third wool fibers is 8% - 20%.

[0015] Preferably, the third wool fiber is any one or a combination of three counts of 66s, 64s or 60s.

[0016] Preferably, the weight ratio of the 90s wool fiber in the wear-resistant wool yarn is 12%, the weight ratio of the 80s wool fiber in the wear-resistant wool yarn is 70%, the weight ratio of the 70s wool fiber in the wear-resistant wool yarn is 10%, the weight ratio of the 66s wool fiber in the wear-resistant wool yarn is 6%, and the weight ratio of the 60s wool fiber in the wear-resistant wool yarn is 2%.

[0017] The second aspect of the present invention provides a wear-resistant wool fabric, which is processed and made from the wear-resistant wool yarn as described above through a knitting process.

[0018] The third aspect of the present invention provides an application of the wear-resistant wool fabric as described above in textile clothing and seats. The textile clothing includes tops and trousers, and the seats include sofas, car seats and office chairs.

[0019] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0020] The wear-resistant wool yarn of the present invention is processed and finished by using the semi-worsted process with wool fibers of different counts in a specific proportion. The performance is optimized by utilizing the following synergistic effects: The first wool fiber, accounting for 5% - 15%, has a relatively fine fiber diameter, which can provide a delicate surface touch, making the fabric made of the yarn feel softer and smoother, and improving the comfort and high-grade feeling of the product. At the same time, the fineness of the first wool fiber makes it more evenly distributed in the yarn, reducing the friction between the fibers, reducing the fiber damage caused by friction, and thus improving the anti-wear performance of the yarn; The second wool fiber, accounting for 65% - 80%, has good felting properties. During spinning and subsequent finishing processes, the density between the fibers can be enhanced through the felting effect. This high-density structure not only improves the strength and wear resistance of the fabric, but also makes the fabric have better elasticity and recovery, and can better resist the stretching and deformation of external forces, maintaining the shape and appearance of the fabric. In addition, the appropriate proportion of the second wool fiber can also balance the softness and rigidity of the yarn, making it have a certain degree of support while maintaining comfort; The third wool fiber, accounting for 5% - 20%, has a relatively thick fiber diameter, which can form a rigid skeleton structure in the yarn. This skeleton structure effectively inhibits the displacement and deformation of the fibers when subjected to external forces, enhancing the anti-wear ability of the yarn. At the same time, the addition of the third wool fiber can also improve the stability and anti-tensile performance of the yarn, making it not easy to break or deform when subjected to tensile force, and further improving the durability of the yarn.

[0021] The fabric made of the wear-resistant wool yarn of the present invention is used to test the wear resistance of the fabric sample according to the standard of GB / T21196.2-2007 using a Martindale wear tester, and its wear resistance far exceeds that of other pure wool fabrics.

[0022] According to the third aspect of the present invention, the present invention also provides the application of the wear-resistant wool yarn in seat surface materials, clothing fabrics and other textiles, which can significantly improve the durability and comfort of products and meet the needs of consumers for high-quality textiles.

[0045] Comparative Example 1

[0046] As a comparison, a non-blended single 60s pure wool fiber is made into yarn and fabric through the same semi-worsted process as a control sample.

[0047] Experimental Example

[0048] The fabric samples made from each embodiment and comparative example are all subjected to the Martindale abrasion resistance test according to the method specified in the national standard GB / T21196.2 - 2007. The test conditions are: a load of 12 kPa, using standard wool abrasives, and the test process is that the fabric to be tested and the abrasives perform Lissajous curve planar motion. The specific test results are shown in the following table:

[0049] Sample Number Wear Resistance (unit: times) Example 1 ≥210000 Example 2 ≥240000 Example 3 ≥170000 Example 4 ≥180000 Example 5 ≥160000 Example 6 ≥170000 Example 7 ≥180000 Example 8 ≥160000 Example 9 ≥150000 Example 10 ≥160000 Comparative Example 1 ≥15000

[0050] It can be seen from the experimental results in the above table that the wool yarn fabrics prepared in each embodiment of the present invention all exhibit excellent abrasion resistance, and the number of abrasion-resistant revolutions is generally above 150,000 revolutions. Among them, the abrasion resistance of Example 2 is the best, reaching 240,000 revolutions. In contrast, for the fabric made of a single-count pure wool fiber in Comparative Example 1, the fibers inside the fabric had obvious wear after only 15,000 revolutions, and the abrasion resistance was significantly lower than that of each embodiment of the present invention.

[0051] These results fully demonstrate that by precisely controlling the combined ratio of wool fibers of different counts, the present invention can significantly improve the wear resistance of wool yarns and their products, making them far superior to traditional single-count pure wool yarns, and having important practical value and market application prospects.
