Cloth Cleaning Process

The filter usually has an endless cloth, traveling intermittently between the plates via roUers, to peel off cakes. Unfortunately, if the cloth is damaged anywhere, the whole cloth must be replaced, which is a difficult process. Each time the filter cloth zigzags through the filter, the filtering direction is reversed this tends to keep the cloth clean. Most of these filters incorporate membranes for mechanical expression, and cakes sometimes stick to the membranes and remain in the chamber after discharge. Some vertical filters are available with a separate cloth for each frame. The cloths maybe disposable and such filters are designed to operate with or without filter aids. 

In almost all cleaning processes, unwanted materials (grease, dirt, color, bacteria) need to be removed from surfaces or cloth (cotton, synthetics, wool). 

Regardless of the cleaning process, you should always wear a basic minimum of safety clothing. Lab coats do more than just protect your street clothes if a dangerous chemical spills on a lab coat, the coat can be easily taken off at a moment s notice with no embarrassment. Street clothes often cannot be removed with equal ease and modesty, and they can provide time for a toxic or dangerous chemical to soak through to your skin.

A competing CO2 dry cleaning process was marketed by Global Technologies. Instead of a conventional basket unit, the system, called DryWash, uses jets of liquid CO2 to agitate clothing [40]. 

In the mid-1970s nylon velour, a material with a soft feel and a variety of possible color combinations, came into use. Today s seat coverings are mainly nylon or polyester cloth. Though leatlier is a renewable resource, the process to make it ready for use in the automobile is not a clean process, requiring large amounts of chemicals. The nylon and polyester materials have a relatively smaller processing impact on the environment and are easily recycled. 

Garments can be thrown away after use (disposable clean room overalls), or reused after cleaning. If clothes are used that are cleaned in house, validation of this process will not be easy. Therefore, the use of clothing cleaned and packaged by specialised and, preferably, certified companies is preferred. 

The rubbing machine is covered with a hood, and an exhaust fan is used to prevent the diffusion of the dust from the rubbing cloth and alignment material. After the rubbing process, a cleaning process is used to wash away particles of the rubbing cloth and alignment material from the surface of the substrate.
