Description

Technical Field

[0001] This application relates to the field of textile yarn technology, specifically to an elastic fiber chenille yarn. Background Technology

[0002] Chenille yarn, with its unique velvety texture and excellent decorative properties, occupies a significant position in many fields such as home textiles, clothing, and decorative fabrics. Its rich pile structure gives products a soft, comfortable feel and a distinctive visual effect, making it popular with consumers and designers alike. It is generally made from a variety of raw materials such as cotton, viscose, acrylic, and polyester through pure spinning or blending.

[0003] In the weaving process, traditional chenille yarn is usually composed of core yarn and decorative yarn. The decorative yarn is sandwiched between two core yarns and twisted to make chenille yarn. However, traditional chenille yarn has poor elasticity. When the fabric is stretched or rubbed by external force, the yarn cannot return to its original shape in time, which can easily lead to fiber fatigue and breakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an elastic fiber chenille yarn, which has advantages such as being less prone to breakage and having strong coverage of the core yarn, thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: an elastic fiber chenille yarn, comprising an inner core layer, an intermediate elastic layer outside the inner core layer, and an outer decorative layer outside the intermediate elastic layer. The inner core layer comprises high-strength polyester filaments, the intermediate elastic layer comprises multiple polyether ester elastic fibers, each of the polyether ester elastic fibers being spirally and uniformly wound on the surface of the inner core layer, and the outer decorative layer comprising multiple pile yarns, each of the pile yarns being bolt-shaped and uniformly wound on the outer surface of the intermediate elastic layer, with the spiral direction of the pile yarns opposite to that of the polyether ester elastic fibers.

[0006] The above-described three-layer structure, consisting of an inner core layer, a middle elastic layer, and an outer decorative layer, fully utilizes the characteristics of each layer's materials. The inner core layer provides a solid skeleton for the yarn, ensuring its overall strength and stability. The middle elastic layer enhances the yarn's elasticity and tensile strength, effectively dispersing external forces and reducing yarn breakage. The outer decorative layer creates a rich nap, improving the decorative effect. The reasonable weight distribution among the inner core layer, middle elastic layer, and outer decorative layer allows each layer's material properties to complement each other, improving the yarn's overall performance, reducing the likelihood of yarn breakage, increasing weaving efficiency and product quality, and ensuring the product's appearance quality and durability.

[0007] Furthermore, the high-strength polyester filament is made of polyester core yarn, and high-temperature resistant silicone additives are added to the interior of the high-strength polyester filament.

[0008] Through the above scheme, the high-strength polyester filament with polyester core yarn can withstand greater tensile and frictional forces, providing reliable skeleton support for the yarn and ensuring that the yarn is not easily broken during weaving and use. In addition, the internal high-temperature resistant silicone additives effectively prevent high temperatures from damaging the internal structure of the fiber and prevent the core yarn molecular chains from breaking, thereby maintaining the strength and stability of the core yarn, thus ensuring the overall strength and durability of the yarn.

[0009] Furthermore, each of the polyether ester elastic fibers is made of polyurethane elastic fiber.

[0010] Through the above scheme, the material with polyether ester elastic fibers has high elasticity and good resilience, and can deform within a large range and quickly return to its original shape. It can effectively disperse stress, prevent the intermediate elastic layer from directly bearing excessive tensile force, reduce the occurrence of yarn breakage, and maintain good dimensional stability of the yarn.

[0011] Furthermore, appropriate viscose staple fibers are added to the interior of each of the polyether ester elastic fibers.

[0012] The above-described scheme, which incorporates viscose staple fibers, allows for a tighter bond between each polyether ester elastic fiber. This tight bond prevents fiber slippage and separation, ensuring the stability of the yarn structure. This helps reduce yarn breakage during production and improves production efficiency.

[0013] Furthermore, the interior of each of the polyether ester elastic fibers is filled with silica.

[0014] Through the above scheme, the addition of silica can make the molecular chains of elastic fibers more tightly bonded, making the yarn less prone to breakage when subjected to external stretching, and able to withstand greater tension and stress, thus improving the yarn's durability and reliability.

[0015] Furthermore, each of the aforementioned yarns is made of acrylic fiber.

[0016] Through the above scheme, the material characteristics of the pile yarn have good hand feel and fluffiness, and the pile yarn can form a rich pile structure, providing a good decorative effect for the yarn. At the same time, it increases the surface area of ​​the yarn, increases the contact area between the yarn and the external environment, and enhances the warmth and moisture absorption of the yarn.

[0017] Furthermore, the number of polyether ester elastic fibers is three, and the number of yarns is six.

[0018] The above scheme, which involves three polyether ester elastic fibers and six pile yarns being evenly wound in a forward and reverse spiral pattern around the outside of the inner core layer, enhances the elasticity and tensile strength of the yarn, while ensuring that the yarn has a rich pile feel and a good decorative effect, thereby improving the overall performance of the yarn.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This elastic fiber chenille yarn employs a three-layer structure consisting of an inner core layer, a middle elastic layer, and an outer decorative layer. This structure fully utilizes the characteristics of each layer. The inner core layer provides a solid skeleton for the yarn, ensuring its overall strength and stability. The middle elastic layer enhances the yarn's elasticity and tensile strength, effectively dispersing external forces and reducing yarn breakage. The outer decorative layer creates a rich nap, enhancing the decorative effect. The reasonable weight distribution among the inner core layer, middle elastic layer, and outer decorative layer allows the complementary performance advantages of each layer, improving the overall performance of the yarn, reducing the possibility of yarn breakage, increasing weaving efficiency and product quality, and ensuring the product's appearance quality and durability.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 and Figure 3This embodiment of an elastic fiber chenille yarn includes an inner core layer 1, an intermediate elastic layer 2 outside the inner core layer 1, and an outer decorative layer 3 outside the intermediate elastic layer 2. This three-layer structure (inner core layer 1, intermediate elastic layer 2, and outer decorative layer 3) fully utilizes the characteristics of each layer. The inner core layer 1 provides a solid framework for the yarn, ensuring its overall strength and stability. The intermediate elastic layer 2 enhances the yarn's elasticity and tensile strength, effectively dispersing external forces and reducing yarn breakage. The outer decorative layer 3 creates a rich nap, improving the decorative effect. The reasonable mass ratio among the inner core layer 1, intermediate elastic layer 2, and outer decorative layer 3 allows the complementary performance advantages of each layer, improving the overall performance of the yarn and reducing... The possibility of yarn breakage is reduced, improving weaving efficiency and product quality, and ensuring the appearance quality and durability of the product. The inner core layer 1 includes high-strength polyester filament 101, which is made of polyester core yarn. The high-strength polyester filament 101 has an added high-temperature resistant silicone additive 102. The high-strength polyester filament 101 with the above-mentioned polyester core yarn material can withstand greater tensile and frictional forces, providing reliable skeleton support for the yarn and ensuring that the yarn is not easily broken during weaving and use. In addition, the internal high-temperature resistant silicone additive 102 effectively prevents high temperature from damaging the internal structure of the fiber and prevents the core yarn molecular chain from breaking, thereby maintaining the strength and stability of the core yarn, thus ensuring the overall strength and durability of the yarn.

[0024] Please see Figure 1 , Figure 2 and Figure 4The intermediate elastic layer 2 includes multiple polyether ester elastic fibers 201. Each polyether ester elastic fiber 201 is made of polyurethane elastic fiber. The polyether ester elastic fiber 201 has high elasticity and good resilience, and can deform within a large range and quickly return to its original shape. It can effectively disperse stress, prevent the intermediate elastic layer 2 from directly bearing excessive tensile force, reduce the occurrence of yarn breakage, and maintain good dimensional stability of the yarn. Each polyether ester elastic fiber 201 is spirally and uniformly wound around the inner core layer 1. The outer decorative layer 3 comprises multiple strands of yarn 301, each strand of yarn 301 being uniformly wound in a bolt-like shape around the outer surface of the intermediate elastic layer 2. The spiral direction of the yarn 301 is opposite to that of the polyether ester elastic fiber 201. Appropriate viscose short fibers 202 are added inside each polyether ester elastic fiber 201. The aforementioned addition of viscose short fibers 202 allows for a tighter cohesion between each polyether ester elastic fiber 201. This tight cohesion prevents slippage and separation between fibers, ensuring the stability of the yarn structure. This helps reduce yarn breakage during production and improves production efficiency. Each polyether ester elastic fiber 201 is also filled with silica 203. This addition of silica 203 further strengthens the bond between the molecular chains of the elastic fibers, making the yarn less prone to breakage under external tension. This allows the yarn to withstand greater tensile and stress forces, improving its durability and reliability.

[0025] Please see Figure 1 , Figure 2 and Figure 5 Each yarn 301 is made of acrylic fiber. The material properties of the yarn 301 provide a good hand feel and fluffiness, and the yarn 301 can form a rich pile structure, providing a good decorative effect for the yarn. At the same time, it increases the surface area of ​​the yarn, increases the contact area between the yarn and the external environment, and enhances the warmth and moisture absorption of the yarn. There are three polyether ester elastic fibers 201 and six yarns 301. The three polyether ester elastic fibers 201 and six yarns 301 are evenly wound in a forward and reverse spiral pattern on the outside of the inner core layer 1, which can enhance the elasticity and tensile strength of the yarn, and ensure that the yarn has a rich pile feel and a good decorative effect, thereby improving the overall performance of the yarn.

[0026] This embodiment of an elastic fiber chenille yarn utilizes a three-layer structure consisting of an inner core layer 1, a middle elastic layer 2, and an outer decorative layer 3. This structure fully leverages the characteristics of each layer. The inner core layer 1 provides a solid framework for the yarn, ensuring its overall strength and stability. The middle elastic layer 2 enhances the yarn's elasticity and tensile strength, effectively dispersing external forces and reducing yarn breakage. The outer decorative layer 3 creates a rich nap, enhancing the decorative effect. The reasonable mass ratio among the inner core layer 1, middle elastic layer 2, and outer decorative layer 3 allows the complementary performance advantages of each layer, improving the overall performance of the yarn, reducing the possibility of yarn breakage, increasing weaving efficiency and product quality, and ensuring the product's appearance quality and durability.

[0027] The working principle of the above embodiment is as follows: This elastic fiber chenille yarn adopts a unique three-layer structure design, consisting of an inner core layer 1, a middle elastic layer 2, and an outer decorative layer 3 from the inside out. Each layer works in concert with the others. The inner core layer 1 serves as the core support structure of the yarn, using high-strength, wear-resistant polyester core yarn to provide a solid skeleton support for the entire yarn. Furthermore, the internal high-temperature resistant silicone additive 102 effectively prevents high temperatures from damaging the internal structure of the fiber, further improving the strength and stability of the core yarn. The middle elastic layer 2 is composed of six polyurethane elastic fibers 201, which are spirally and evenly wound around the outside of the inner core layer 1. When the yarn is stretched by an external force, the middle elastic layer 2 deforms, absorbing and dispersing the external force, reducing the tension on the core yarn layer. When the external force is removed, the middle elastic layer 2 can quickly return to its original state, ensuring that the yarn does not break down during repeated stretching and recovery processes. Significant deformation occurs, and the viscose short fibers 202 and silica 203 inside the polyether ester elastic fiber 201 can more tightly bind together each polyether ester elastic fiber 201. This makes the yarn less prone to breakage when subjected to external stretching, and can withstand greater tensile and stress forces. Then, the outer decorative layer 3 is made of six pile yarns 301 wound around the outside of the middle elastic layer 2 in a spiral direction opposite to that of the polyether ester elastic fiber 201. The pile yarns 301 can reduce the direct friction and damage of the internal structure to the external environment, while increasing the surface area of ​​the yarn and improving the yarn's warmth retention and moisture absorption. The pile yarns 301 are wound around the middle elastic layer 2 in a spiral direction opposite to that of the polyether ester elastic fiber 201, which enables the polyether ester elastic fiber 201 and the pile yarns 301 to form a better cohesion, enhance the connection stability between the two, further reduce the possibility of yarn breakage, and improve the product quality of the yarn.
