PET wood pulp spunlace non-woven fabric is a composite non-woven fabric made from PET (polyethylene terephthalate, i.e., polyester) fibers and wood pulp fibers through the spunlace process. It is essentially the same as "polyester wood pulp spunlace non-woven fabric" (since PET fibers are often referred to as polyester). The following is an explanation from a more precise perspective of raw material characteristics and processes:
PET Fibers (Polyester)
As synthetic fibers, they have the characteristics of high strength, wear resistance, good dimensional stability, etc. They also have excellent oil absorption, enabling the non-woven fabric to quickly absorb and lock in oil when in contact with it, facilitating cleaning.
They have strong chemical stability, are not easily corroded by acids and alkalis, and have a certain degree of oil absorption, making them suitable for absorbing oil in cleaning scenarios.
They are widely available and relatively cost-effective, making them a commonly used synthetic fiber raw material in non-woven fabric production.
Wood Pulp Fibers
They are cellulose fibers extracted from natural wood through pulping processes and belong to natural renewable resources.
They have excellent water absorption (can absorb several times their own weight in water) and soft skin-friendliness, which can improve the tactile feel of the non-woven fabric and its ability to adsorb liquids.
They are biodegradable and can be decomposed gradually in the natural environment, to a certain extent improving the environmental performance of pure PET non-woven fabrics.
Fiber Mixing and Web Formation: PET fibers and wood pulp fibers are mixed in proportion, opened, and carded to form a uniform fiber web (the two types of fibers are randomly distributed, laying the foundation for subsequent entanglement).
High-Pressure Spunlace Entanglement: High-pressure water streams (with pressures ranging from tens to hundreds of bars) are sprayed onto the fiber web through nozzles. The impact force of the high-pressure water causes PET fibers and wood pulp fibers to interweave and entangle with each other, forming a stable non-woven fabric structure (no adhesives such as glue are needed, and the structure is formed by physical action).
Post-Processing: After dehydration, drying, and shaping, it is cut into rolls or sheets according to requirements. Some products will undergo functional treatments such as antibacterial and antistatic treatments.
Composite Function: The combination of the high water absorption of wood pulp and the high strength of PET makes it suitable for water absorption scenarios (such as cleaning water stains) and can withstand the tension of repeated wiping, not easy to break.
Balance between Softness and Durability: Wood pulp fibers endow it with a soft touch, suitable for contact with the skin or precision surfaces (such as electronic screens); PET fibers ensure tear resistance during use.
Environmental Characteristics: The wood pulp component is biodegradable, making it more acceptable to the environment than pure PET non-woven fabrics (but the complete degradability still depends on the proportion of PET).
Dust-Free Property: The fibers are tightly entangled during production, and they are not easy to shed or generate lint during use, making them suitable for scenarios with high cleanliness requirements (such as laboratories and electronics factories).
Cleaning Field: Kitchen wet wipes (oil and water absorption), industrial wipes (for cleaning equipment/parts), car interior cleaning wipes, etc.
Personal Care: Disposable facial towels, makeup remover pads (soft and skin-friendly, not easy to irritate the skin).
Medical Assistance: Medical hand towels, cleaning cloths around wounds (need to meet hygiene standards).
In short, PET wood pulp spunlace non-woven fabric, through the complementary advantages of natural and synthetic fibers, has become a functional, comfortable, and practical non-woven material, widely used in daily and industrial scenarios.
