Ultrasonic Sewing Machine for Bleached Cloth – Ultrasonic Cutting – Cheersonic

The product is bleached by chemical methods to remove various impurities, stains, natural oil wax, and pigments from grey cloth. The purpose of bleaching is to remove natural pigments and impart a necessary and stable whiteness to the fabric. After scouring, the appearance of cotton fabrics is not clean enough due to the presence of natural pigments on the fibers, which can affect the brightness of the color when used for dyeing or printing. The purpose of bleaching is to remove pigment and impart a necessary and stable whiteness to the fabric, without significant damage to the fiber itself. The commonly used bleaching methods for cotton fabrics include sodium hypochlorite method, hydrogen peroxide water method, and sodium chlorite method. The pH value of the sodium hypochlorite bleaching solution is about 10, and it is carried out at room temperature.

The equipment is simple, convenient to operate, and the cost is low. However, the strength of the fabric is greatly damaged, and the whiteness is low. The pH value of the hydrogen peroxide bleaching solution is 10. When bleached at high temperatures, the whiteness of the bleached fabric is high and stable, with a good feel, and it can also remove pulp and natural impurities. The disadvantages are high equipment requirements and high costs. Under suitable conditions, combined with caustic soda, desizing, scouring, and bleaching can be completed at one time. The pH value of sodium chlorite bleaching solution is 4 to 4.5, which is carried out at high temperatures. It has the advantages of good whiteness and little damage to fibers. However, during bleaching, it is prone to generate toxic gases, pollute the environment, and corrode equipment. The equipment needs to be made of special metal materials, so its application is subject to certain restrictions. After bleaching with sodium hypochlorite and sodium chlorite, dechlorination is necessary to prevent the fabric from being damaged due to the presence of residual chlorine during the presence process.

Ultrasonic bleached cloth welding offers some key advantages over other forms of welding: It saves time. It is much faster than traditional welding methods, as virtually no time is needed for drying or curing. It is a highly automated process, which also saves on manpower and helps you get the parts you need faste. Ultrasonic welding has some advantages ,such as high precision, low cost , high speed and it produces very little noise, performed without any lubrication and doesn’t use chemicals in its process.These machines are highly versatile so they can be easily modified for different applications such as cutting glass, plastic, ceramics, etc.
