Full-cross lapped Nonwoven Fabric Products

I. Process Flow of full-cross lapped spunlace Nonwoven Fabric

The production of full-cross lapped spunlace nonwoven fabric is a process with extremely high precision and technical requirements. Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd., relying on its mature production system and professional technical team, strictly controls every production step to ensure stable and reliable product quality. The specific process flow is as follows:

Raw material selection and blending: The company strictly controls quality from the source, selects high-quality natural fibers (such as pure cotton fibers), synthetic fibers (such as polyester, nylon, viscose fibers, etc.) or mixed fibers as production raw materials. The technical team will design the fiber ratio scheme according to the performance requirements of the product, for example, by adjusting the proportion of natural fibers and synthetic fibers to balance the softness and strength of the product, ensuring that the raw materials meet the requirements of the subsequent production process and lay the foundation for product performance.

Opening and mixing: First, the packaged fibers are disintegrated by opening equipment, using mechanical force to remove impurities and short fibers, making the fibers fluffy and uniform. Then, the disintegrated fibers enter the mixing equipment, and are fully mixed according to the preset ratio scheme to ensure the uniform distribution of different types and different performance fibers, avoiding fiber agglomeration, and providing uniform fiber raw materials for the subsequent lamination process.

Lamination into net: The mixed fibers enter the high-precision lamination machine, where the needle cloth components in the lamination machine operate at high speed, performing fine separation, straightening, and directional arrangement of the fibers, processing the fibers into continuous, uniform, and uniform-thickness fiber nets. During this process, technicians will monitor parameters such as the thickness and uniformity of the fiber net in real time, adjusting the speed of the lamination machine, needle cloth density, etc., to ensure a stable fiber net structure and prepare for the subsequent water-stitching reinforcement process.

full-cross lapped spunlace reinforcement (core process): This is the key step that distinguishes full-cross lapped spunlace nonwoven fabric from other water-stitching processes. The formed fiber net is conveyed to the all-cross water-stitching machine, where the equipment uses multiple sets of high-pressure water nozzles to spray cross-shaped high-pressure water jets in different directions and angles onto the fiber net. Compared with semi-cross lapped spunlace processes, the water jet spraying angles are more diverse and the coverage is more comprehensive. The high-pressure water will drive the fibers in the fiber net to intertwine and interweave, forming a dense and uniform three-dimensional mesh structure. Company technicians will precisely control the pressure of the high-pressure water (usually in 5-15 MPa), spraying frequency, and arrangement of water nozzles to ensure sufficient fiber entanglement, stable fabric structure, and avoid excessive spraying that may cause fiber damage.

Drying and heating: After spunalce reinforcement, the wet nonwoven fabric is advanced into a vacuum dehydration equipment, where negative pressure adsorption is used to remove 70%-80% of the moisture from the fabric surface, reducing the energy consumption of the subsequent drying process. Then, the dehydrated nonwoven fabric enters a hot air drying equipment, where it is dried under constant temperature (usually 100-130°C) and wind speed conditions, with the moisture content controlled at 8% or less. During the drying process, the equipment will monitor the temperature and humidity of the fabric surface in real time to prevent fiber aging due to excessive temperature or affect product performance due to incomplete drying. At the same time, it will further improve the flatness and stability of the fabric surface.

Post-treatment processing: According to the personalized needs of customers, the company will conduct targeted post-treatment processing on the non-woven fabric after drying. Common post-treatment processes include: softening treatment (by adding softening agents to enhance the fabric surface feel), antibacterial treatment (using environmentally friendly antibacterial agents to give the product antibacterial properties and inhibit bacterial growth), anti-static treatment (reducing static electricity accumulation on the fabric surface, suitable for special scenarios such as electronics and medical), waterproof treatment (through coating or immersion processes to enhance the product's waterproof performance), etc. The addition of post-treatment processes enables the product to have more special functions, meeting the usage requirements of different industries.

Cutting and inspection: Finally, the non-woven fabric rolls after post-treatment enter the cutting equipment, which are cut into rolls or sheets according to the width and length specifications required by the customer. After cutting, the quality inspectors will conduct a comprehensive inspection of the products, including appearance (checking for defects, color differences on the fabric surface), physical properties (testing the tensile strength, elongation at break, breathability, etc.), and functionality (such as antibacterial rate, waterproof performance, etc.), ensuring that each batch of products meets national relevant standards and customer requirements, and only qualified products can be stored for shipment.

II. Advantages of full-cross lapped spunlace non-woven fabric

Superior physical strength and durability: Thanks to the full-cross lapped spunlace reinforcement process, the entanglement of fibers is more compact and uniform, and the longitudinal and transverse tensile strength of the product are excellent, with little difference in strength between the two directions, and the fabric surface has strong resistance to tearing and abrasion. In actual use, even when subjected to external stretching or friction, it is unlikely to cause damage or breakage, and the service life is much longer than that of ordinary cross-stitch non-woven fabric products, suitable for scenarios with high strength requirements.

Excellent uniformity and stability: From raw material mixing to carding into a net, and then to full-cross lapped spunlace reinforcement, every step is precisely controlled, ensuring that the weight uniformity and thickness uniformity of the product are at the industry-leading level, with no obvious uneven thickness or defects.
