In the production of spunlace non - woven fabrics, the choice of raw materials is like a painter's brush in the hands of a craftsman, skillfully outlining the performance profile of the product and playing a decisive role in product quality. Different raw materials and their combinations endow spunlace non - woven fabrics with diverse characteristics, enabling them to meet the needs of different fields.​

Wood pulp fiber is one of the commonly used raw materials for spunlace non - woven fabrics. It has excellent water absorption, like a powerful sponge, capable of quickly absorbing a large amount of liquid. This characteristic makes wood pulp fiber perform outstandingly in applications that require high hygroscopicity. For example, in the field of hygiene products, such as sanitary napkins and diapers, it can quickly absorb and lock in the liquid, keeping the surface dry and providing users with a comfortable and hygienic experience. At the same time, the spunlace non - woven fabric made of wood pulp fiber has a soft hand feel and is very comfortable when it adheres to the skin, without a rough feeling, especially suitable for products that come into direct contact with the skin.​

Viscose fiber is known for its good hygroscopicity and drapability. Its hygroscopicity enables the spunlace non - woven fabric to better absorb and retain moisture. In products such as facial masks and medical dressings, it can provide sufficient moisture nourishment for the skin or wounds, promoting healing. The drapability of viscose fiber gives the spunlace non - woven fabric an elegant texture, which feels smooth and soft when touched, increasing the comfort and aesthetics of the product. However, viscose fiber also has some disadvantages, such as low wet strength and being prone to deformation in a humid environment, which to a certain extent limits its single use.​

Polyester fiber brings strong and durable qualities to spunlace non - woven fabrics with its strength and wear resistance. It has high tensile strength and can withstand large external forces without being easily broken. This makes the spunlace non - woven fabric containing polyester fiber perform well in applications that require high strength, such as industrial wiping cloths and synthetic leather base fabrics. Polyester fiber also has good dimensional stability. Under different environmental conditions, its shape and size are not easy to change, ensuring the stability and reliability of the product. But polyester fiber has poor hygroscopicity, which may require mixing with other fibers in some occasions with high requirements for hygroscopicity.​

In actual production, in order to obtain spunlace non - woven fabrics with better comprehensive performance, a variety of raw materials are often used in combination. For example, mixing wood pulp fiber with polyester fiber can combine the high water absorption of wood pulp fiber and the high strength of polyester fiber, making the product have both good liquid absorption performance and sufficient strength, and being suitable for more application scenarios. Different combinations and proportions of raw materials will lead to differences in product performance. By precisely adjusting the proportion of raw materials, spunlace non - woven fabrics that meet specific requirements can be customized.​

The raw material formula of spunlace non - woven fabrics is both an art and a science. By skillfully selecting and combining different raw materials, products with various unique performances can be created to meet the diverse needs of the market. With the continuous progress of science and technology and the in - depth research on material properties, the raw material formulas of spunlace non - woven fabrics will be more abundant and innovative in the future, opening up broad space for their applications in more fields.
