Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a polyester-nylon ultrafine filament nonwoven fabric with a spunlace pattern. Background Technology
[0002] Polyester-nylon nonwoven fabric is a functional material made of polyester (PET) and nylon (PA6) composites. It combines the advantages of both fibers, possessing high strength, moisture absorption and quick-drying properties, and antibacterial properties. It is widely used in medical, industrial, and home furnishing fields. The polyester-nylon composite fiber web is formed into a three-dimensional structure through hydroentangling, combining the heat resistance of polyester (melting point 265℃) and the abrasion resistance of nylon, making it suitable for high-intensity applications. In existing technologies, polyester-nylon nonwoven fabric is usually made by laying polyester-nylon short fibers together. When wiping and cleaning mirrors or precision instruments, or when used in products such as wet wipes, face masks, bath towels, and bed sheets, fiber shedding is likely to occur. It is also not water-resistant and is prone to breakage after repeated washing, affecting the user experience and product lifespan of the nonwoven fabric. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this utility model provides a polyester-nylon ultrafine filament nonwoven fabric with a spunlace pattern. This solves the problem that existing polyester-nylon nonwoven fabrics are usually made by laying polyester-nylon short fibers together. When wiping and cleaning mirrors or precision instruments, or when used in products such as wet wipes, face masks, bath towels, and bed sheets, the fibers are prone to shedding and are not resistant to washing. After repeated washing, they are easily broken, affecting the user experience and product lifespan.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a polyester-nylon ultrafine filament nonwoven fabric with a spunlace pattern, comprising a nonwoven fabric body, wherein the nonwoven fabric body is composed of multiple layers of fiber web, the fiber web is composed of ultrafine filament fibers, and the interior of the ultrafine filament fibers is provided with polyester fiber segments and nylon fiber segments, the polyester fiber segments and nylon fiber segments being arranged alternately.
[0005] Preferably, the fineness of the single filament of the ultrafine filament fiber is 2.5-3.1D.
[0006] Preferably, the thickness of the ultrafine filament fiber is 0.5-3 mm.
[0007] Preferably, the surface of the nonwoven fabric body is provided with a hydroentangled pattern.
[0008] This invention provides a polyester / nylon microfiber nonwoven fabric with a spunlace pattern. It offers the following advantages: This spunlace pattern polyester / nylon microfiber nonwoven fabric, through the coordination of the nonwoven fabric body, fiber web, microfibers, polyester fiber segments, and nylon fiber segments, forms an orange-petal-shaped cross-section fiber by the interlacing of individual polyester and nylon fiber segments. Through the superposition of multiple fiber webs and processes such as spunlace and fiber opening, the microfibers are irregularly entangled to form a three-dimensional structure, thereby improving the strength and abrasion resistance of the nonwoven fabric. It effectively increases the friction and bonding force between fibers, making the nonwoven fabric less prone to fiber shedding when used for wiping, cleaning, or as a wet wipe. Even after multiple washes, it maintains good integrity and strength, improving the washability and extending the service life of the nonwoven fabric, thus enhancing the user experience.
[0009] By combining ultrafine filament fibers, polyester fiber segments, and nylon fiber segments, and using PET and PA6 chips as raw materials, the process involves high-temperature melting and extrusion of the fibers, followed by the extrusion of filaments through a specific spinneret (hollow 16 segments), forming a segmented cross-section fiber composed of 8 polyester fiber segments and 8 nylon fiber segments. Before fiber opening, the ultrafine filament fibers have a single filament fineness of 2.5-3.1D. The raw filaments are stretched by a high-speed airflow, producing a splitting effect during high-speed movement. Compared with the short fibers of traditional nonwoven fabrics, ultrafine filament fibers have a greater number of segments, increasing the fiber surface area and enhancing the capillary effect, thereby improving the water absorption rate. This makes the nonwoven fabric have superior water absorption and stain removal performance when wiping and cleaning. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] In the existing technology, polyester-nylon nonwoven fabric is usually made by laying polyester-nylon short fibers together. When wiping and cleaning mirrors or precision instruments, or when used in products such as wet wipes, face masks, bath towels and bed sheets, it is easy for fibers to fall off. It is also not resistant to washing and is easy to break after repeated washing, which affects the user experience of the nonwoven fabric and the product's lifespan.
[0014] In view of this, the present invention provides a polyester-nylon microfiber nonwoven fabric with a spunlace pattern. Through the coordination of the nonwoven fabric body, fiber web, microfiber, polyester fiber segments, and nylon fiber segments, the microfiber is formed by the cross-distribution of individual polyester and nylon fiber segments to create an orange-petal-shaped cross-section. Through the superposition of multiple fiber webs and processes such as spunlace and fiber opening, the microfiber is irregularly entangled to form a three-dimensional structure, improving the strength and abrasion resistance of the nonwoven fabric, increasing the friction and bonding force between fibers. This makes the nonwoven fabric less prone to fiber shedding when used for wiping or as a wet wipe, and it maintains good integrity and strength even after multiple washes. This improves the washability of the nonwoven fabric, extends its service life, and thus enhances the user experience.
[0015] Depend on Figure 1-3 It is known that a polyester-nylon ultrafine filament nonwoven fabric with a spunlace pattern includes a nonwoven fabric body 1, which is composed of multiple layers of fiber web 2. The fiber web 2 is composed of ultrafine filament fibers 4. Polyester fiber segments 5 and nylon fiber segments 6 are arranged inside the ultrafine filament fibers 4, and the polyester fiber segments 5 and nylon fiber segments 6 are arranged alternately. In the specific implementation process, it is worth noting that through the cooperation between the nonwoven fabric body 1, the fiber web 2, and the ultrafine filament fibers 4, the ultrafine filament fibers 4 undergo specific processing. By arranging the ultrafine filament fibers 4 in multiple directions to form the fiber web 2, and by stacking multiple layers of fiber web 2 and undergoing processes such as hydroentangling and fiber opening, the nonwoven fabric body 1 is formed, which has the characteristics of high strength, wear resistance, moisture absorption and quick drying, while effectively avoiding the problem of fiber shedding. Through the cooperation between the ultrafine filament fibers 4, polyester fiber segments 5, and nylon fiber segments 6, PET and PA6 chips are melted and extruded at high temperature, and the filaments are spun out by a specific spinneret (hollow 16 segments). The original filaments are stretched by a high-speed airflow, and a splitting effect is produced in the high-speed movement, forming a structure consisting of 8 polyester fiber segments 5 and 8 nylon segments. The nonwoven fabric features orange-petal-shaped cross-section fibers with 6 intersecting polyester and nylon fiber segments. Through the interplay of the nonwoven fabric body 1, fiber web 2, ultrafine filament fibers 4, polyester fiber segments 5, and nylon fiber segments 6, the ultrafine filament fibers 4 are formed by the intersecting distribution of 8 polyester fiber segments 5 and 8 nylon fiber segments 6, creating an orange-petal-shaped cross-section. Through the layering of multiple fiber webs 2 and processes such as hydroentangling and fiber opening, the ultrafine filament fibers 4 are irregularly entangled to form a three-dimensional structure. This improves the strength and abrasion resistance of the nonwoven fabric, increases the friction and bonding force between fibers, and makes the nonwoven fabric less prone to fiber shedding when used for wiping, cleaning, or as wet wipes. Even after multiple washes, it maintains good integrity and strength, improving the washability and extending the service life of the nonwoven fabric, thus enhancing the user experience. Furthermore, the fineness of the single filament of the ultrafine filament fiber 4 is 2.5-3.1D; In the specific implementation process, it is worth noting that through the combination of ultrafine filament fiber 4, polyester fiber segments 5, and nylon fiber segments 6, using PET and PA6 chips as raw materials, the fibers are melted and extruded at high temperature by the equipment, and then filaments are extruded through a specific spinneret (hollow 16 orange segments), forming an orange-segment shaped cross-section fiber composed of 8 polyester fiber segments 5 and 8 nylon fiber segments 6. Before fiber opening, the ultrafine filament fiber 4 has a single filament fineness of 2.5-3.1D. The original filament is drawn by a high-speed airflow, and during high-speed movement... The nonwoven fabric body 1 is rolled after hydroentangling and alkali treatment to create a splitting effect, which opens the orange-petal-shaped cross-section fibers. The fineness of the yarn after opening is 0.14-0.19D, further refining the fiber structure and increasing the interlacing points between fibers. This effectively improves the softness and skin-friendliness of the nonwoven fabric. Compared with the short fibers of traditional nonwoven fabrics, the ultra-fine filament fibers 4 have more segments, increasing the surface area of the fibers and enhancing the capillary effect, thereby improving the water absorption rate and making the nonwoven fabric more effective in wiping and cleaning. Furthermore, the thickness of the ultrafine filament fiber 4 is 0.5-3mm; In the specific implementation process, it is worth noting that the ultra-fine filament fiber 4 is arranged in multiple directions by a cross-laying machine to form a fiber web 2. By laying the fiber web 2 in multiple layers, a multi-layer mesh structure with a thickness of 0.5-3mm is formed to facilitate subsequent hydroentangling and rolling operations. Furthermore, the surface of the nonwoven fabric body 1 is provided with a hydroentangled pattern 3; In the specific implementation process, it is worth noting that the multi-layer fiber web 2 is sprayed onto the multi-layer fiber web 2 by high-pressure water jet (200-400 bar), leaving a unique hydroentangled pattern 3 on the surface of the nonwoven fabric body 1. This is not only aesthetically pleasing, but also enhances the three-dimensionality and layering of the nonwoven fabric, improves the visual effect of the product, and causes the ultra-fine filament fibers 4 to entangle irregularly, forming a three-dimensional structure, improving the anisotropy of mechanical properties, thereby improving the overall strength and abrasion resistance of the polyester-nylon nonwoven fabric.
