- Making bristles for a brush can involve a variety of processes, and these can differ greatly depending on whether the bristles are made from natural or synthetic materials. Here is a simplified explanation of both:
**Natural Bristles**:
1. **Harvesting**: Natural bristles are harvested from animals. For example, hog bristles are commonly used in paint brushes, and these are obtained from the neck and back of the hog. Horsehair is another common material for brush bristles.
2. **Cleaning**: The harvested hair is cleaned to remove any dirt and oils. This might involve washing the hair with soap and water, followed by a rinse in clean water.
3. **Sorting**: The cleaned hair is then sorted according to its length, thickness, and color. This can be a time-consuming process, as it's often done by hand to ensure accuracy.
4. **Bundling**: The sorted hairs are bundled together and tied at one end. This bundled end will form the base of the brush, where the bristles are secured into the brush handle.
**Synthetic Bristles**:
1. **Extrusion**: The bristle material (often nylon or polyester) is heated until it melts and can be extruded through small holes to form thin strands. The strands cool and harden into bristles.
2. **Cutting**: The extruded strands are cut to the desired length.
3. **Treatment**: The cut strands might be treated to give them certain characteristics. For example, they might be tapered to a point, roughened to improve their paint-holding capacity, or dyed a certain color.
4. **Bundling**: Like natural bristles, synthetic bristles are bundled together for insertion into the brush handle.
In both cases, the bundled bristles are secured into the brush handle, often with the help of a ferrule (a metal piece that wraps around the base of the bristles and the top of the handle). The base of the bristles might be dipped in glue before the ferrule is applied, to help hold the bristles in place. Then the finished brush is checked for quality, packaged, and ready to be shipped.
