Preparing fibers for various applications can usually benefit from die cutting. Here at Colvin-Friedman, we have more than 75 years of experience processing and die-cutting fibers of all kinds and look forward to helping you either in the fiber preparation and cutting stage or into the fabric stage as well.
Some of the most common fibers we see in projects for our clients include:
- Glass Fiber
- Carbon Fiber
- Natural Fibers (Cotton, hemp, etc.)
- Synthetic Polymer Fibers (Nylon, etc.)
- And many more
Issues that Arise in Fiber Die Cutting
| We use specialized coatings or resins to bind fibers before cutting as needed, or adjust cutting speed and pressure to minimize fraying. |
| We use one of two options: either cooled tools or external cooling systems to maintain fiber integrity. |
| Some fibers must point in a specific direction, so we use specialized clamping systems and cutting plans to maintain directionality. |
| While ultrasonic cutting is one option, experienced die cutters can also use multi-layer dies that ensure proper cuts of each layer. |
| Some fibers prove tougher to cut, and careful inspections will ensure pressure adjustments to match the cutting resistance observed. |
| Using anti-ionizing bars and humidity controls keeps fibers aligned and separated, increasing the effective run rate for production. |
| Special care must be taken with the waste of fiber die cutting processes, so we take special care that our ventilation and vacuum systems are functioning at maximum capacity before starting runs. |

Production Capabilities
Even with the painstaking care we take to ensure that no issues arise during the fiber die cutting process, we are still able to ramp up runs to meet our clients’ demands, all while maintaining the tight tolerances to complex designs that they deserve. Our two most common processes are rotary and flatbed, and we’ve listed their output and input figures for review:
| Lead Time (Average) |

Common Types of Fiber and Their Die Cutting Processes
Grouped more generally into synthetic and natural fibers, these are the building blocks of fabrics, carpets, filters, and much more. To give a better sense of the myriad options that can be handled with die cutting, we’ve put together two tables to outline the applications and what process we generally use when fiber die cutting specific types for our clients.
Synthetic Fibers
| Polyester |
Strong, durable synthetic fiber with excellent resilience and moisture resistance. Easy to die cut and holds shape well. |
Filtration materials, geotextiles, apparel |
Rotary die cutting |
| Nylon |
Tough, abrasion-resistant fiber with high tensile strength. Good elasticity and moisture-wicking properties. |
Automotive components, industrial fabrics, carpets |
Flatbed die cutting |
| Polypropylene |
Lightweight, chemical-resistant fiber with good tensile strength. Low moisture absorption and easy to die cut. |
Geotextiles, filters, disposable products |
Rotary die cutting |
| Acrylic |
Soft, wool-like fiber with excellent color retention and resistance to sunlight. Good insulation properties. |
Craft felts, clothing insulation, upholstery |
Flatbed die cutting |
| Polyethylene |
Flexible, lightweight fiber with high impact strength and chemical resistance. Easy to die cut but may require cooling. |
Packaging materials, disposable medical textiles |
Rotary die cutting |
Natural Fibers
| Cotton |
Soft, breathable natural fiber with good absorbency. Biodegradable and easy to die cut, but may fray. |
Natural fiber composites, eco-friendly products, apparel |
Rotary or flatbed die cutting |
| Wool |
Natural protein fiber with excellent insulation and moisture-wicking properties. Resilient and flame-resistant. |
Insulation, felts, high-end apparel |
Flatbed die cutting |
| Hemp |
Strong, durable natural fiber with antimicrobial properties. Biodegradable and environmentally friendly. |
Sustainable composites, textiles, paper products |
Flatbed die cutting |
| Jute |
Coarse, strong natural fiber with good insulating and antistatic properties. Biodegradable and low-cost. |
Eco-friendly packaging, geotextiles, composites |
Rotary die cutting |
| Flax (Linen) |
Strong, absorbent natural fiber with good heat conductivity. Resistant to static and lint, but may fray when cut. |
High-quality textiles, composites, insulation |
Flatbed die cutting |
