Which paper variety is produced without requiring filler materials ?
Show answer Hide answer
Answer: C. Blotting paper
Explanation
Blotting paper is made to be highly absorbent, so mineral filler materials are omitted. Omitting fillers prevents mineral particles from blocking the microscopic capillary spaces inside paper. High porosity and absorbency define blotting paper and require the complete absence of fillers. Paper manufacturing typically incorporates mineral fillers to improve opacity, smoothness, and printability. Cellulose fibers form a porous network that naturally absorbs liquids through capillary action. Specialty papers require tailored manufacturing processes to achieve specific functional properties.
Blotting paper is used to absorb excess wet ink from handwritten documents or artwork. Absorbent paper products are also utilized in laboratory settings for filtration and drying. Understanding paper chemistry allows manufacturers to optimize products for distinct applications. Option A represents high-quality writing paper which typically contains fillers for better ink retention. Option B includes standard stationery papers that utilize mineral fillers for opacity and smoothness. Option D involves dyed papers which often contain mineral fillers and sizing agents.
