Soluble fiberboards mainly include the following types:
Tencel fiber: Tencel fiber has a smooth surface and a relatively regular round or oval cross-section, with a skin-core structure.
Modal fiber: Modal fiber has 1 to 2 grooves in the longitudinal direction, and the cross-section is similar to a waist-round shape, which is relatively smooth and has a skin-core structure.
Soybean fiber: The surface of soybean fiber has irregular grooves and island-like bumps, and the cross-section is flat dumbbell-shaped and waist-round.
Bamboo fiber: The surface of bamboo fiber has grooves, the cross-section is serrated, and it has a skin-core structure.
Chitin fiber: The surface of chitin fiber has obvious grooves, the cross-section is serrated at the edge, and the core layer has obvious small gaps.
Viscose fiber: The surface of viscose fiber has grooves, the cross-section is serrated, and it has a skin-core structure.
Cotton fiber: Cotton fiber is flat and ribbon-shaped longitudinally, with natural twists, and has a rounded cross section with a central cavity.
Silk: Silk has a smooth surface and an irregular triangular cross section.
Wool fiber: Wool fiber has curls longitudinally, scales on the surface, and a round or oval cross section.
Polyester fiber: Polyester fiber is rod-shaped, smooth on the surface, and round in cross section.
These fiberboards are widely used in industry and daily life, such as in the petroleum, chemical, electric power, steel, cement, glass, ceramics and other industries.
