Detailed Process Flow: Manufacturing Xylem Fiber and Wood Cellulose The production of high-quality wood cellulose , especially specialized products like Xylem Fiber, involves a series of carefully controlled physical and chemical processes. This ensures the precise removal of non-cellulose components while preserving the integrity and desired characteristics of the cellulose fibers. Our manufacturing process emphasizes precision, sustainability, and strict adherence to international quality standards, ensuring a consistent and high-performance product. 1. Raw Material Sourcing and Preparation The journey begins with responsibly sourced wood, primarily from sustainably managed forests. Common wood types include softwood (e.g., pine, spruce) and hardwood (e.g., birch, eucalyptus), selected for their optimal cellulose content and fiber morphology. The wood logs undergo mechanical debarking to remove bark, followed by chipping into uniform wood chips, typically 10-30 mm in size, to facilitate efficient and consistent processing in subsequent stages. 2. Pulping Process: Cellulose Extraction from Wood This is the core stage where lignin, hemicellulose, and other non-cellulose components are separated from the cellulose fibers. Two primary pulping methods are commonly employed: Kraft Process (Sulfate Pulping): Wood chips are cooked in a highly alkaline solution of sodium hydroxide (NaOH) and sodium sulfide (Na₂S) – known as white liquor – under elevated temperature and pressure (typically 150-170°C, 8-10 bar) for several hours. This process efficiently dissolves lignin while preserving the strength of the cellulose fibers, yielding strong, unbleached pulp. The cooking duration, temperature, and chemical concentrations are meticulously controlled to achieve desired fiber properties and minimize degradation. Sulfite Process: Utilizes acidic solutions, typically sulfurous acid (H₂SO₃) and a bisulfite salt, to dissolve lignin. This method often results in a brighter pulp with a higher hemicellulose content compared to the Kraft process and is preferred for specific paper grades or dissolving pulps requiring specific chemical reactivity. For our Xylem Fiber, a modified Kraft process is predominantly utilized due to its superior efficiency in achieving high fiber strength and purity, making it ideal for robust industrial applications demanding consistent mechanical performance. 3. Washing and Screening After pulping, the resulting pulp slurry is thoroughly washed in multi-stage countercurrent washing systems to remove residual cooking chemicals, dissolved lignin, and other impurities. This step is critical for chemical recovery and minimizing environmental impact. Subsequent screening and centrifugal cleaning processes remove knots, shives, and other oversized or foreign particles, ensuring a uniform fiber length distribution and purity, which are critical parameters for downstream processing and end-use performance. 4. Bleaching (Optional, for higher purity and brightness) If a high-whiteness or high-purity product (e.g., for specialized filters or chemical derivatives) is required, the pulp undergoes a multi-stage bleaching process. Modern bleaching sequences are designed to be environmentally friendly, often employing Elemental Chlorine Free (ECF) methods using chlorine dioxide, or Totally Chlorine Free (TCF) methods utilizing agents like oxygen, ozone, or hydrogen peroxide. This step enhances optical properties and removes any remaining lignin and extractives, yielding a brighter fibre made from wood pulp with desired purity levels. 5. Refining and Drying Refining involves mechanically treating the cellulose fibers to enhance their fibrillation, increasing their surface area and improving their bonding potential. This process is carefully controlled to tailor the properties of the cellulose wood fibers for specific end-uses, such as increased strength in composites or improved water retention in construction materials. Finally, the refined pulp is dewatered using presses and then dried, often through flash dryers or roll dryers, to a precisely specified moisture content (typically 5-10%) before being pressed into bales or packaged as individual fibers for shipment. Testing Standards: Throughout the entire process, rigorous quality control testing is performed to ensure product consistency and adherence to specifications. This includes monitoring key parameters such as fiber length distribution (e.g., using Kajaani fiber analyzers), freeness (Schopper-Riegler), brightness (ISO 2470), kappa number (indicating residual lignin content, ISO 302), and chemical purity (ash content, extractives, TAPPI T 203 om-09).

Our products offer controlled distributions, from short fibers (tens to hundreds of microns) for improved surface finish to longer fibers (several millimeters) for enhanced mechanical reinforcement. Purity (Alpha Cellulose Content): High alpha-cellulose content (typically >96%) indicates minimal presence of lignin and hemicellulose, leading to greater inherent fiber strength, improved chemical inertness, and stability, particularly important for applications requiring high chemical resistance or thermal stability. Water Retention Value (WRV): WRV reflects the fiber's capacity to absorb and retain water. This property is crucial for applications in construction (e.g., preventing premature drying of mortars), thickeners, and rheology modifiers, influencing workability and final product integrity. Specific Surface Area: A high specific surface area enhances the bonding capabilities with other matrix materials (e.g., polymers, cement) and improves adsorption properties, making it valuable in filtration and composite applications. Bulk Density: Important for handling, storage, and dosage accuracy in formulation. We offer various bulk densities depending on the refining and drying process, allowing for optimization in transportation and mixing. pH Stability: Ensuring a neutral to slightly alkaline pH value allows for compatibility with a wide range of chemical environments and formulations, preventing undesirable reactions or degradation.
