Which manufactured fiber is made from coal or petroleum , often blended with other fibers , and as great washing ability?

Polyester

Polyesters are naturally occurring chemicals and a synthetic polymer (plastic) produced by mixing ethylene glycol and terephthalic acid. Polyester is any fabric which is produced from polyester yarns or fibers and is highly used  in clothing. Polyester fabric has great washing ability, dries quickly, resist wrinkling, and is resistant to many chemicals.  

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
