Ultrasonic Drilling Nonwoven Fabric Products
Product Description
Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. has been deeply engaged in the field of nonwoven fabrics for many years. By pursuing the ultimate pursuit of material research, process innovation and quality control, it has become a professional manufacturer with a good reputation in the industry. Based on the diverse market demands for composite functional fabrics, the company has meticulously developed ultrasonic drilling nonwoven fabrics. These fabrics are based on a variety of high-quality raw materials such as polyester, viscose, silk, bamboo fiber, all-cotton, etc., and through the core ultrasonic drilling composite process, two or more layers of nonwoven fabric are precisely combined. They can not only build a sandwich structure to enhance water absorption and other characteristics, but also adapt to various composite material requirements, providing efficient solutions for water-absorbing pads and multiple composite scenarios.
In terms of raw material selection, the company adheres to the concept of "quality originates from the foundation", choosing polyester, viscose, silk, bamboo fiber, all-cotton, and other high-quality substrates for ultrasonic drilling nonwoven fabrics. It also supports different raw material combinations for 2 layers, 3 layers, and multiple layers. For water absorption needs, viscose, silk, all-cotton, and bamboo fiber can be used as the core layer; for strength requirements, polyester can be used as the supporting layer; for skin-friendly requirements, silk, all-cotton, etc. are preferred. The scientific combination of multiple substrates and layer design, combined with the empowerment of ultrasonic drilling technology, enables the precise matching of product functions and scene requirements from the source.
Core advantages: Process empowerment, diverse functions
As the core process advantage product of the company, ultrasonic drilling nonwoven fabrics rely on unique composite technology to achieve a dual breakthrough in structural stability and functional diversity. The core advantages are particularly prominent:
- Ultrasonic core technology, strong and environmentally friendly composite: Using the integrated technology of ultrasonic drilling composite, the high-frequency vibration generates heat to instantly fuse the fibers of each layer of substrate, without the need for chemical adhesives such as glue, fundamentally ensuring the environmental friendliness of the product, without any odor or harmful residues. At the same time, the interlayer bonding strength is far greater than traditional composite methods, and it is not prone to delamination even after repeated use or force application, with excellent structural stability.
- Precise drilling design, strong function adaptability: During the composite process, precise drilling is completed simultaneously. The hole diameter, hole spacing, and drilling density can be customized according to requirements. The drilling structure not only enhances the breathability and water/air permeability efficiency of the fabric, but also improves the adhesion to other materials, adapting to various functional requirements such as water absorption, filtration, and ventilation, especially providing core support for the "rapid penetration - efficient retention" of water-absorbing pads.
- Multi-layer multi-material customization, flexible function combination: Supports 2- multiple layers of different material combinations customization, and can be combined with "hydrophilic + support", "skin-friendly + wear-resistant", "antibacterial + ventilation" and other multi-functional combinations according to scene requirements. For example, in water-absorbing scenarios, a "skin-friendly layer + high water-absorbing layer + leak-proof layer" sandwich structure is used; in filtration scenarios, a "dense layer + breathable layer" double-layer structure is adopted. It can flexibly meet the functional requirements of different industries.
- Excellent basic performance, wide application scenarios: Relying on the inherent advantages of the nonwoven fabric base cloth, the product has excellent tensile strength, tear strength, and soft texture. After ultrasonic composite, it retains the comfort and durability of single-layer nonwoven fabric while expanding the functional boundaries through the multi-layer structure and drilling design, suitable for from intimate products to industrial materials in various scenarios.
Advanced production technology: Precise control, efficient empowerment
The outstanding quality of ultrasonic drilling nonwoven fabrics stems from the company's "base cloth refinement + process empowerment + full-process quality control" refined production system. The production process is based on customized base cloth and realizes the simultaneous completion of composite and drilling through ultrasonic technology. The entire process is efficient and environmentally friendly, and the key links are as follows: 1. Customized base fabric production: According to the customer's functional requirements, an exclusive raw material formula is designed for each layer of base fabric - the functional core layer (such as water-absorbing, antibacterial layer) uses corresponding characteristic substrates (viscose, bamboo fiber, etc.), the structural support layer uses high-strength substrates (polyester, etc.), and the skin-friendly layer uses natural substrates (100% cotton, silk, etc.). Each layer is processed through sorting, loosening, mixing, combing, cross-laying, high-pressure water-stitch reinforcement and other processes to ensure that the performance of each layer of base fabric meets the standards.
2. Pre-treatment and alignment of base fabric: Each layer of base fabric is dried and shaped to remove excess moisture and calibrate the size, ensuring the flatness and consistency of the layers during the layering process; through an automated conveying and positioning system, multiple layers of base fabric are precisely aligned, and the layering sequence and gap are adjusted according to the design requirements, laying the foundation for the subsequent compounding.
3. Ultrasonic punching and core compounding process: Using a high-precision ultrasonic compounding punching integrated machine, adjust the ultrasonic power, frequency and punching mold (controlling the hole diameter and spacing) according to the preset parameters. During operation, the high-frequency vibration causes the contact points of multiple layers of base fabric to instantaneously fuse, while the mold completes the punching, achieving "compounding-punching" completion simultaneously, which not only improves production efficiency but also ensures the punching position and compounding accuracy, avoiding the impact of secondary processing on product performance.
4. Post-processing and functional upgrade: After the ultrasonic punching and compounding process, the product undergoes rolling, cutting and other processes to optimize the surface texture and size accuracy; for specific requirements, additional functional post-treatment such as antibacterial, anti-static, waterproof (local) can be carried out to further expand the product's application range and enhance product value.
5. Full-process quality control system: Each layer of base fabric needs to be tested for weight, strength, functional characteristics (such as water absorption, breathability); the finished product after compounding needs to be tested for interlayer peel strength, punching accuracy, environmental protection indicators and corresponding functional indicators (such as water absorption ratio, filtration efficiency), ensuring that each batch of products meets the customer requirements and industry standards.
