What types of singeing equipment are there? What is used to singe the clothing? There are three types of singeing machines: gas singeing machine, copper plate singeing machine and cylinder singeing machine. The gas singeing machine is to quickly pass the original cloth through a flammable gas flame to burn off the fluff on the cloth surface; the copper plate singeing machine is to quickly rub the fabric on a hot, fixed arc-shaped copper or alloy plate to Burn to remove fluff; the cylinder singeing machine is improved from the copper plate singeing machine, using a rotating hot cast iron or cast iron alloy cylinder instead of a fixed copper plate.
Copper plate singeing machine
It has a complex structure, a large area, and high labor intensity. The preparation and completion of the copper plate singeing machine takes a long time. It needs to be ignited about 1 hour in advance to burn the metal plate or cylinder until it is red hot. , to start singeing. Metal materials such as copper and cast iron are easily oxidized by oxygen in the air under red-hot conditions, resulting in greater loss; cleaning and maintenance work is troublesome, poor variety adaptability, thin and easy to scratch, and are not suitable for singeing jacquards and light fabrics. However, the finish after singeing is high and suitable for low-pole cotton.
Gas singeing machine
Gas singeing machine is currently the most widely used type of singeing machine. The gas singeing machine is suitable for all kinds of textiles, especially for jacquard fabrics, and the singeing quality is relatively uniform. It has simple structure, convenient operation, low labor intensity and short preparation time. The heat energy is fully utilized and the flame is easy to control. The gas singeing machine has little impact on room temperature during operation. However, a corresponding gas heat source is required.
Singeing quality assessment
The measurement standard of singeing quality is currently mainly judged by the degree of fluff removal, but it must be ensured that the fabric is not damaged (no damage, minimal loss of fabric strength). The specific method is to place the singed fabric under better light, and refer to the standards for visual rating:
The singeing quality of general fabrics should reach Level 3~4, those with high quality requirements should reach level 4 or above, and thin fabrics should reach level 3.
Common defects
Dirty singeing
The distance between the inner flame and the cloth is too large, and the temperature of the copper plate or cylinder is not enough
Solution: Adjust the height of the inner flame or raise the copper plate or cylinder Temperature
Holes or cut edges in singeing
Drag yarn, edge yarn, neps, etc. are extinguished promptly after burning
Solution: shorten the distance between the fire outlet and fire extinguishing
Sparks fall on the cloth surface on, it was not extinguished in time
Solution: Change the atomizing nozzle or increase the vaporization temperature. The gasoline is poorly vaporized and oil droplets are sprayed onto the cloth
The vehicle speed is too slow
Solution: Speed up the vehicle
The vehicle speed is too fast
Solution: Slow down the vehicle speed
The drying and brushing devices are not functioning
Solution: Clean the brush and emery roller, adjust the contact surface with the fabric to increase Drying effect
Excessive singeing (burning, hardening or melting of polyester, excessive shrinkage of fabric)
The temperature during singeing is too high or the fabric is thin and there are many burners. Solution: Adjust the flame temperature and adjust Number of singeing surfaces
When polyester and vinylon blended fabrics are singed, the fabric temperature is too high. Solution: Strengthen the blowing cooling between the burners.
The vehicle speed is too slow. Solution: Speed up the vehicle.
Uneven singeing. (Singed strips or uneven left and right)
The burner is plugged or deformed, and the surface of the copper plate and cylinder is uneven
Solution: clear the burner or correct the gap in the burner, or plan the iron plates on both sides of the burner
> Inconsistent temperatures at both ends of the copper plate and cylinder
Solution: File the copper plate or flatten the cylinder
Fabric wrinkles
Solution: Improve the operation and adjust the fabric tension guide roller to maintain the edge suction device Flexible
