A blue roll, also known as blue hand roll, is primarily made from paper pulp.
Composition of Blue Roll
Here's a breakdown of the components and processes involved in making a blue roll:
Paper Pulp
- The base material for blue roll is paper pulp. This is derived from processed wood fibers.
- This pulp forms the main structure of the paper towels.
Chemical Treatments
- Chemicals are used to treat the paper pulp. These chemicals enhance the paper's properties such as strength and absorbency.
- These treatments are standard in paper towel production.
Bleaching
- The paper is then bleached. This process removes any color from the pulp and creates a whiter base.
- Bleaching helps in achieving a consistent final product color.
Dyeing
- Once bleached, the paper is dyed to give it the distinctive grey-blue color.
- This specific dye distinguishes blue rolls from other paper towel products.
Hydrophilic Agent (Sometimes)
- Some blue rolls are treated with a hydrophilic agent.
- This agent enhances the absorbency of the paper, allowing it to soak up liquids more efficiently.
Summary of Blue Roll Components
| Component | Purpose |
|---|---|
| Paper Pulp | Base material, provides structure |
| Chemical Treatments | Enhances strength and other properties |
| Bleaching | Removes color, creates a white base |
| Dye | Provides the signature blue-grey color |
| Hydrophilic Agent | Increases absorbency (sometimes) |
Practical Insights
- Blue rolls are designed for general cleaning and spill absorption.
- They are mass-produced and cost-effective, making them popular in various settings such as kitchens, garages, and workshops.
