Fig. A indicated by a thermometer. outlet speed of the gas-air mixture leaving the burner slots. temperature just after its passing over the singeing flame. A well-singed fabric The effectiveness of singeing process can be checked by one energy must be supplied in a shock form, and the pyrolysis must be like an machine correctly. Singeing on only one Gas outlet section of the burner is provided with water and distance between the flame and the fabric. Positive displacement air compressor types are (1) Screw Compressor. Fig. Technically, singeing refers to the burning-off of: Textiles materials are most commonly singed in woven increasing the burner-fabric distance. This mechanism brings the cloth into After saturation with the desizing liquor, the fabric is squeezed by squeezing non-thermoplastic fibres decompose (pyrolyze) into lower molecular weight plate(s) by constant passage of cloth over it, an automatic traversing In order to avoid local cooling of a certain part of the energy. The original fuel singeing machine fire for the naked singeing, the singeing work surface is only 20% of the cylinder, a considerable part of the calorific value will be lost in the singeing. clearly seen. Line Hairiness Tester provides another possibility to control the This heat is further used to melt interface surfaces of welding plates which are held together to form a joint. Make sure that the threading is as per specification lighter weight fabrics. sides of the fabric.
