Fabric cutting processes commonly employ high-speed CM or YM series laser cutting machines, typically equipped with a 50mm focusing lens. The regular speed for single-layer cutting rests at 5 meters per minute, with a light intensity of 40%. Factors such as air pump power, honeycomb bottom plate quality and flatness, as well as laser intensity, impact the precision of fabric damage. Higher light intensity corresponds to increased thermal radiation, potentially leading to gaps in delicate materials. A prominent challenge in cutting operations is the occurrence of fabric yellowing.
To mitigate this, proper procedure involves placing the fabric flat on the honeycomb bottom plate, activating an exhaust fan to promptly remove smoke generated during cutting, preventing fabric yellowing. Additionally, an air compressor should be engaged to ensure consistent airflow, removing impurities and soot from the cut. For enhanced results, employing an inert gas like nitrogen is preferable for the air-blowing process.
- Cutting Ordinary Fabrics
For lightweight and thin fabrics such as non-woven, polyester, silk, satin, and twill, ensuring precise incisions necessitates using a 50mm focusing lens to generate fine spots and minimize slit size. External laser machine equipment, including air extraction and air blowing systems, should be activated. The fabric must be securely affixed to the honeycomb bottom plate. Utilizing a high-power air pump and compressor for air blowing is recommended.
Adjusting speed and light intensity is critical. Larger or smoother sections of a pattern can be cut at higher speeds, approximately 3-10 meters per minute for CM machines, while smaller or intricately curved parts require slower speeds, around 0.5-3 meters per minute. Light intensity corresponds to speed: higher speeds demand greater light intensity, while lower speeds necessitate reduced intensity, typically ranging from 30% to 60%. To match light intensity size for straight lines and curved transitions, values generally remain between 5% and 15%.
- Special Fabric Cutting Requirements
Unique fabrics such as white cotton, clean cloth, and fabrics containing PC and plastic components have specific processing demands. White cotton must avoid yellowing post-cut, clean cloth should retain its color, and incisions must not harden. For such fabrics, a 50mm focusing lens, preferably an imported RF laser, is recommended to ensure consistent spot quality and stability.
Ventilation and air blowing systems should be activated, and nitrogen is preferable for white cotton cutting if possible. Optimal settings involve speeds of 1.5-3 meters per minute and light intensities between 20% and 30%. Balancing medium speed with appropriate light intensity prevents discoloration and hardening of incisions. Excessively high speeds require increased light intensity, which may compromise incision quality due to excessive heat.
