The main properties of ultrafine fibers include soft and delicate hand feel, high strength, high water and oil absorption, high cleaning ability, soft luster, and high-density structure. These properties make ultrafine fibers widely used in multiple fields.
Soft and delicate hand feel
The diameter of ultrafine fibers is very small, usually below 5 microns, which makes their bending stiffness very low and their hand feel particularly soft and delicate. The bending stiffness of fibers is proportional to the fourth power of their diameter, so the finer the fibers, the softer the hand feel.
High strength
Ultra fine fibers have high strength and can withstand large external forces without easily breaking. This is due to its higher orientation and crystallinity, which allows the fibers to better maintain structural integrity when subjected to external forces.
High water absorption and oil absorption
Due to the large specific surface area of ultrafine fibers, more capillary pores are formed, which makes them excellent in water and oil absorption. This characteristic makes ultrafine fibers have important applications in the fields of cleaning and filtration.
High cleaning ability
The extremely fine diameter of ultrafine fibers makes them resemble sharp scrapers, with strong core suction and efficient surface cleaning.
Soft luster
The luster of ultrafine fibers is soft because their small diameter makes light reflection more dispersed, presenting a soft luster, similar to the luster of real silk.
High density structure
During the weaving process, ultrafine fibers are more prone to deformation and adhesion, forming high-density fabric structures. This high-density structure makes the fabric more compact, with better waterproof and cleaning effects.
