This type of conveyor belt uses fiber fabric as the core and general rubber as the covering material, with a smooth and flat surface. The core is a layered or integral fabric woven from fibers such as cotton, nylon, polyester, or vinylon.

Cotton fiber is the earliest used core material and bonds easily with rubber. Its strength slightly increases when wet, but its breaking strength is low (mostly around 56 N/(mm·layer)), and its anti-corrosion and mildew resistance is poor — its use is gradually decreasing.

Nylon fiber fabrics, introduced in the late 1950s, have become the most widely used type. Nylon fiber has a strength of up to 700 N/(mm/layer), is water-resistant, corrosion-resistant, and resistant to bending fatigue, though elastic elongation is relatively large.

Polyester fiber has similar properties to nylon, but its elastic elongation during use is only half that of nylon, making it a promising development material.

Vinylon fiber has a strength of 200 N/(mm·layer), a smaller elastic elongation than nylon, bonds well with rubber, and has good heat resistance. However, its strength decreases by 10–25% when wet, and it is only used in a few countries.

When weaving the core, only one type of fiber can be used, or two types of fibers can be blended or interwoven.
