Staple fiber can be natural or synthetic and are having shorter lengths as they are only few inches long. They are twisted and drawn together to form long strands. Wool is a natural fiber where as Polytrimethylene terephthalate  (PTT), Polypropylene (PP) & Nylon (NY) can be made either Stapled or BCF where as BCF Yarn stands for Bulk Continuous Filament yarn which is a long continuous strand of filament produced through specialized extrusion process using polymers like PET, PP, PBT and Nylon.

Overall, carpet produced from BCF yarn has higher luster than the carpets produced from stapled fiber. Since BCF has low density thus produced low weight carpets. Its amplified light reflection makes the product appear bulkier whereas carpets produced from staple fiber has matt or dull finish similar to wool.
