Description

Technical Field

[0001] This utility model relates to the field of polyester filament technology, specifically to a high-elasticity, ultra-soft, fine denier polyester filament. Background Technology

[0002] Polyester filament is made from polyester fibers. Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate—obtained from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-processed. Polyester filament refers to yarns with a length of over one kilometer. In daily life, polyester filament has a wide range of uses, with a large amount used in the manufacture of clothing and industrial products, providing people with diverse choices in clothing.

[0003] The polyester filaments currently in use have poor abrasion resistance. To ensure their abrasion resistance, abrasion-resistant materials, such as nylon fiber materials, are usually added to the polyester filaments. However, this will affect the elasticity and softness of the polyester filaments. Therefore, we propose a high-elasticity, ultra-soft fine denier polyester filament. Utility Model Content

[0004] The purpose of this invention is to provide a highly elastic, ultra-soft, fine denier polyester filament to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-elasticity, ultra-soft, fine denier polyester filament, comprising an inner filament and a cylindrical polyester long fiber, which is retained as the raw filament after high-speed spinning through a textile structure. The inner filament is finally processed through a stretching and deformation structure. The surface of the inner filament is provided with antibacterial filaments, and the surface of the antibacterial filaments is provided with abrasion-resistant filaments. The abrasion-resistant filaments consist of reinforcing filaments and flexible filaments. There are six groups of abrasion-resistant filaments and three groups of antibacterial filaments. Warm-insulating filaments are provided between the three groups of antibacterial filaments.

[0006] Preferably, the reinforcing filament and the flexible filament are nylon fiber and thermoplastic polyurethane, respectively. The nylon fiber and thermoplastic polyurethane are mixed using a blending melt method and then melt-spun into filaments. The abrasion-resistant filament is texturized by a texturing mechanism. Nylon fiber has advantages such as high strength, high abrasion resistance, and good heat resistance, while thermoplastic polyurethane has excellent elasticity, impact resistance, and chemical corrosion resistance. First, the nylon fiber and thermoplastic polyurethane are dried separately to remove moisture and prevent problems such as bubbles and degradation during processing. Then, the dried nylon fiber and thermoplastic polyurethane are added to a twin-screw extruder in a certain proportion. The twin-screw extruder can provide strong shear force and mixing action, so that the two materials are fully and uniformly mixed. During the extrusion process, the melting and mixing effect of the material is ensured by controlling parameters such as temperature, screw speed, and feed rate. Generally, the temperature should be adjusted according to the melting point and processing properties of the material, while the screw speed and feed rate need to be optimized based on the equipment performance and mixing requirements. Finally, the extruded mixture is cooled and granulated to obtain blended particles of nylon fiber and thermoplastic polyurethane. These blended particles are then dried to remove moisture. The dried particles are added to a melt spinning machine and melted by heating. The molten mixture is extruded through a spinneret to form a fine stream. This stream cools and solidifies in air to form filaments. These filaments undergo stretching and winding processes to obtain abrasion-resistant yarn.

[0007] Preferably, the insulating yarn is provided in three sets, and the insulating yarn is cotton fiber. Cotton fiber has the characteristics of being soft, warm and skin-friendly, thereby giving the polyester filament a soft, warm and skin-friendly effect.

[0008] Preferably, the three sets of antibacterial and warming fibers are arranged in a ring on the surface of the inner fiber. The antibacterial fibers are bamboo charcoal fibers, which have a strong adsorption capacity. Their rich microporous structure can adsorb harmful substances such as formaldehyde, benzene, toluene, and ammonia in the air, and can play an antibacterial role. By setting the wear-resistant and antibacterial fibers, the feel of fine denier polyester filaments can be improved, making them softer and smoother, and improving the comfort of wearing them.

[0009] Preferably, the antibacterial filaments are cylindrical filaments produced by a blending mechanism.

[0010] Compared with the prior art, this utility model provides a highly elastic, ultra-soft, fine denier polyester filament, which has the following beneficial effects:

[0011] 1. This high-elasticity, ultra-soft fine denier polyester filament features abrasion-resistant yarn made of nylon fiber and thermoplastic polyurethane, which is then textured by a texturing mechanism. The combination of these two materials achieves complementary properties, enhancing both abrasion resistance and overall elasticity and softness.

[0012] 2. This high-elasticity, ultra-soft fine denier polyester filament, through the addition of warming and antibacterial fibers, effectively improves the feel of the polyester filament, giving it a soft, antibacterial, warm, and skin-friendly effect. Attached Figure Description

[0015] like Figure 1 As shown, this utility model provides a technical solution: a high-elasticity, ultra-soft, fine denier polyester filament, including an inner filament 1 and a cylindrical polyester long fiber, which is retained as the raw filament after high-speed spinning through a textile structure. The inner filament 1 is finally processed by a stretching and deformation structure. The surface of the inner filament 1 is provided with antibacterial filaments 2, and the surface of the antibacterial filaments 2 is provided with abrasion-resistant filaments 3. The abrasion-resistant filaments 3 are composed of reinforcing filaments 31 and flexible filaments 32. There are six groups of abrasion-resistant filaments 3 and three groups of antibacterial filaments 2. Warm-insulating filaments 4 are provided between the three groups of antibacterial filaments 2.

[0016] Reinforcing filament 31 and flexible filament 32 are nylon fiber and thermoplastic polyurethane, respectively. The nylon fiber and thermoplastic polyurethane are blended using a melt-spinning method and then produced into filaments. Abrasion-resistant filament 3 is texturized using a texturing mechanism. Nylon fiber possesses advantages such as high strength, high abrasion resistance, and good heat resistance, while thermoplastic polyurethane exhibits excellent elasticity, impact resistance, and chemical corrosion resistance. First, the nylon fiber and thermoplastic polyurethane are dried separately to remove moisture and prevent problems such as bubbles and degradation during processing. Then, the dried nylon fiber and thermoplastic polyurethane are added to a twin-screw extruder in a specific ratio. The twin-screw extruder provides powerful shearing force and mixing action, ensuring thorough and uniform mixing of the two materials. During extrusion, parameters such as temperature, screw speed, and feed rate are controlled to ensure effective melting and mixing of the materials. Generally, the temperature should be adjusted according to the melting point and processing properties of the material, while the screw speed and feed rate need to be optimized according to the equipment performance and mixing requirements. Finally, the extruded mixture is cooled and granulated to obtain blended particles of nylon fiber and thermoplastic polyurethane. The blended particles of nylon fiber and thermoplastic polyurethane are then dried to remove moisture. The dried blended particles are added to a melt spinning machine and melted by heating. The molten mixture is extruded through a spinneret to form a fine stream. The fine stream cools and solidifies in air to form filaments. The filaments are then stretched and wound to obtain abrasion-resistant yarn 3.

[0017] The warming yarn 4 is set in three groups. The warming yarn 4 is cotton fiber. Cotton fiber has the characteristics of being soft, warm and skin-friendly, which makes the polyester filament have the effects of being soft, warm and skin-friendly.

[0018] Three sets of antibacterial filaments 2 and warming filaments 4 are arranged in a ring on the surface of the inner filament 1. The antibacterial filament 2 is made of bamboo charcoal fiber and is a cylindrical filament. It is made by a blending mechanism. Bamboo charcoal fiber has a super adsorption capacity. Its rich microporous structure can adsorb harmful substances such as formaldehyde, benzene, toluene, and ammonia in the air, which can play an antibacterial role. The wear-resistant filament 3 and antibacterial filament 2 can improve the feel of fine denier polyester filament, making it softer and smoother, and improving the comfort of wearing it.

[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
