Description

Technical Field

[0001] This utility model relates to a shape-conserving antistatic eddy current spun yarn, belonging to the field of eddy current spinning technology. Background Technology

[0002] Vortex spinning technology has been widely used in the textile industry due to its advantages such as high spinning speed, high yield, and low hairiness. Vortex-spun yarns typically have a core-sheath structure, resulting in a smooth yarn surface and fabrics that are crisp to the touch, durable, and resistant to pilling.

[0003] However, traditional vortex-spun yarns, especially those made of synthetic fibers such as polyester and nylon, are prone to generating static electricity during use due to friction. This can cause fabrics to attract dust, become uncomfortable to wear, and even pose safety hazards in certain environments. To solve the static electricity problem, antistatic agents are usually added in the finishing process. However, the antistatic effect obtained by this method is not durable and will significantly diminish after multiple washes.

[0004] Furthermore, vortex spinning, especially pure cotton or polyester-cotton blended yarns, makes clothing fabrics prone to deformation (such as elongation and relaxation) after wearing and washing, resulting in poor shape retention and affecting the appearance and durability of the fabric.

[0005] The problem to be solved is how to prepare a shape-preserving, antistatic eddy current spun yarn. Utility Model Content

[0006] The purpose of this invention is to provide a shape-preserving and antistatic eddy current spun yarn, which produces garments with good shape retention and antistatic properties.

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a conformal antistatic eddy current spun yarn, which includes a parallel twisted antistatic eddy current spun yarn and a high twist yarn. The antistatic eddy current spun yarn includes a low elongation core yarn and an antistatic fiber layer covering the outside of the low elongation core yarn. The antistatic fiber layer is made of antistatic polyester fiber or antistatic nylon fiber. The twist of the high-twist yarn is 1200-1500 twists per meter.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the low elongation core yarn is a high-strength low elongation polyester fiber yarn or flax fiber yarn.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the high-twist yarn is high-twist cotton yarn.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the low elongation core yarn also includes ultra-high molecular weight polyethylene filament.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: a high-strength, low-elongation viscose fiber layer is further provided between the antistatic fiber layer and the low-elongation core yarn.

[0012] The beneficial effects of this utility model are as follows: The conformal antistatic eddy current spun yarn involved in this utility model has an outer antistatic fiber layer that has a conductive effect, enabling rapid charge leakage and providing excellent antistatic performance. The core yarn uses a low-elongation core yarn, resulting in a low elongation rate in the prepared eddy current spun yarn, which improves the yarn's resistance to tensile deformation and thus provides excellent shape retention.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1 Combination Figure 1 and Figure 2 This embodiment will be described in detail below. The conformal antistatic eddy current spun yarn involved in this embodiment includes an antistatic eddy current spun yarn 1 and a high-twist yarn 2, which are twisted together. The antistatic eddy current spun yarn 1 includes a low-elongation core yarn 11 and an antistatic fiber layer 12 covering the outside of the low-elongation core yarn; the antistatic fiber layer 12 is made of antistatic polyester fiber or antistatic nylon fiber; the twist of the high-twist yarn is 1200-1500 twists per meter.

[0016] In this embodiment, the low-elongation core yarn 11 is made of high-strength, low-elongation polyester fiber yarn. This fiber yarn has a low elongation rate, which can effectively resist tensile deformation and provide a good shape-preserving foundation for the entire yarn. When the yarn is stretched by an external force, the high-strength, low-elongation polyester fiber yarn can disperse the external force, preventing the yarn from being excessively stretched and deformed, so that the fabric made from it can maintain its original shape during wearing and washing.

[0017] The antistatic fiber layer 12 is made of antistatic polyester fiber. Antistatic polyester fiber has unique conductive properties, allowing it to quickly conduct away the charge generated during friction, effectively preventing the accumulation of static electricity. In daily life, when the fabric rubs against other objects, the antistatic polyester fiber can promptly release the generated static electricity, preventing the fabric from attracting dust, improving wearing comfort, and reducing safety hazards caused by static electricity. Antistatic polyester fiber refers to fiber incorporating an antistatic agent into the entire structure and extruding it together with molten PET chips to create a permanent antistatic effect.

[0018] The high-twist yarn uses cotton yarn with a twist of 1450 twists per meter. The high-twist process tightly binds the fibers within the yarn, enhancing its strength and elasticity. When twisted together with antistatic eddy-spun yarn, the high-twist yarn further enhances the overall stability and durability of the yarn. Furthermore, the presence of high-twist cotton yarn improves the fabric's hand feel, making it softer and more comfortable.

[0019] In actual production, high-strength, low-elongation polyester fiber yarn is first prepared as the low-elongation core yarn. Then, antistatic polyester fibers are evenly wrapped around the outside of the low-elongation core yarn through a vortex spinning coating process to form an antistatic vortex spun yarn. Next, high-twist cotton yarn with a twist within a specified range is twisted together with the antistatic vortex spun yarn to finally obtain the shape-preserving antistatic vortex spun yarn involved in this embodiment.

[0020] Through this combination of structure and materials, the shape-preserving antistatic eddy current spun yarn of this embodiment exhibits excellent performance in practical applications. When manufacturing garments, it ensures that the garments maintain their shape even after prolonged wear and multiple washes, while effectively preventing the generation of static electricity, providing consumers with a better wearing experience.

[0021] Example 2 Combination Figure 3 This embodiment will be described in detail below. The shape-conserving antistatic eddy current spun yarn involved in this embodiment differs from that in Embodiment 1 in that: the low-elongation core yarn 11 is flax fiber yarn. The low-elongation core yarn 11 also includes ultra-high molecular weight polyethylene filaments. A high-strength, low-elongation viscose fiber layer 13 is further disposed between the antistatic fiber layer 12 and the low-elongation core yarn 11.

[0022] Flax fiber yarn, used as a low-elongation core yarn, possesses a natural cooling sensation and excellent moisture absorption, resulting in breathable and comfortable fabrics. Simultaneously, the inherent rigidity of flax fibers enhances the yarn's resistance to deformation, helping to maintain the fabric's shape. The addition of ultra-high molecular weight polyethylene (UHMWPE) filaments further strengthens the low-elongation core yarn and improves its abrasion resistance. UHMWPE filaments exhibit extremely high strength and modulus, with tightly packed molecular chains capable of withstanding significant external forces without easily breaking, thus greatly improving the overall durability of the yarn.

[0023] The high-strength, low-elongation viscose fiber layer placed between the antistatic fiber layer and the low-elongation core yarn serves as a transition and reinforcement. The high-strength, low-elongation viscose fiber layer possesses good flexibility and processability, allowing the antistatic fiber layer to more tightly wrap around the low-elongation core yarn, thus improving the stability of the yarn structure. Furthermore, the high-strength, low-elongation viscose fiber layer also improves the yarn's hand feel, making it softer and smoother.

[0024] The antistatic fiber layer still uses antistatic nylon fiber, which has good abrasion resistance and elastic recovery ability. While ensuring antistatic performance, it also gives the fabric good elasticity and resilience. When the fabric is stretched or twisted by external force, the antistatic nylon fiber can quickly return to its original shape, maintaining the smoothness and appearance of the fabric.

[0025] The high-twist yarn is also selected from high-twist cotton yarn with a twist within the specified range. Its function is similar to that of Example 1, further enhancing the stability and durability of the entire yarn and improving the hand feel of the fabric.

[0026] In actual production, flax fiber yarn and ultra-high molecular weight polyethylene filament are first combined to form a low-elongation core yarn. Then, high-strength, low-elongation viscose fiber yarn is wrapped around it. Next, antistatic nylon fiber is evenly wrapped on the outermost layer using a vortex spinning coating process to form an antistatic vortex spun yarn. Finally, high-twist cotton yarn and antistatic vortex spun yarn are twisted together to obtain the shape-preserving antistatic vortex spun yarn involved in this embodiment.

[0027] In practical applications, this shape-preserving and antistatic eddy-spun yarn not only has excellent shape retention and antistatic effects, but also incorporates the advantages of multiple fibers, resulting in fabrics that are outstanding in terms of comfort, durability, and aesthetics, thus meeting consumers' demand for high-quality fabrics.

[0028] 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.
