Singeing principle and equipment introduction

Gradually passing the grey fabric through a high-temperature flame sprayed by a singeer or rubbing against a red hot gold surface, causing the fluff on the surface of the fabric to heat up and burn without damaging the fabric itself because the fabric is relatively thick, tightly structured and has a cold water roll The cooling and protection are not easy to heat up, so as to achieve the purpose of singeing. The speed of singeing is generally in the range of 70 to 120 depending on the type of fabric.

- The singeing machine is generally composed of several parts such as a feeding frame, a bristle box, a singeing machine, (a rear bristle box), a cooling fire extinguishing device, a falling cloth frame or a rolling device. The function of the bristle box is to let the fabric pass through For several pairs of brush roller boxes, the reverse rotation of the brush roller brush the fluff on the surface of the fabric to facilitate the more thorough burning of the surface villi.The fabric singeing can be divided into gas singeing machine, hot plate burning. Maoji, cylinder singeing machine, etc. Currently, the most common and widely used printing and dyeing plant is the gas singeing machine (Figure 4 - 1), which is commonly used in printing and dyeing plants.The heat sources used are gas, water gas, and gasoline vaporization. Gas, liquefied gas or natural gas, these flammable gases mixed with air in proper proportions can be burnt through the crater to burn out high temperature flames.Copper singeing machine (Fig. 4 and cylinder singer are limited due to the variety of fabrics processed There are not many manufacturers that can use diesel fuel or electric heating to heat metal plates and metal cylinders to a red hot state, especially for heavy fabrics with thick corduroy fabrics and nep impurities. Woven When the product passes through a high-temperature crater or red hot metal surface, the fluff is burned or charred immediately.The singe fabric needs to be cooled by a cold water roller. Immediately after leaving the crater or high temperature cylinder, fire extinguishing measures should be taken, such as steam spraying, or It is a direct padding desizing solution (using a weak alkali or biological enzyme solution) to extinguish the fire.
