Wipe cloths

Surface preparations must be carefully controlled for reliable production of adhesive-bonded parts. If a chemical surface treatment is required, the process must be monitored for proper sequence, bath temperature, solution concentration, and contaminants. If sand or grit blasting is employed, the abrasive must be changed regularly. An adequate supply of clean wiping cloths for solvent cleaning is also mandatory. Checks should be made to determine if cleaning cloths or solvent containers have become contaminated. 

A variety of small-volume wastes are generated by maintenance, analytical, and monitoring activities. These primarily consist of discarded glassware, wipe cloths, gloves, plastic, trash, and paint waste, as well as other monitoring materials. Most of these materials... 

The worktable is another surface with which museum fabrics often come into contact. Hard, nonporous materials such as wood, formica, and glass must not be used as a worktable surface. Because of their nonabsorbent nature, they collect hand grime and other oily matters museum fabrics placed on such a surface naturally serve as a wiping cloth and clean the soiled worktable. (Many fabrics in museums suffer the results the reverse side is extensively soiled while the obverse is still clean.)... 

Combine, using a glass support, a stack of wiping cloths (four times the thickness of the gel), two 3MM filter sheets wetted in denaturation buffer, a wetted nylon membrane cut to the size of the gel and the agarose gel. Nitrocellulose membranes are not recommended for this procedure. 

Toraysee (Fig. 19) is on the other hand a high density woven fabric with ultra-fine fibers, which possesses pores containing micro-pockets (see Fig. 20). These micro-pockets absorb dust or oil, and functions as a highly-efficient wiping cloth. Its high-density surface is also suited for printing. This particular example of Fig. 21 shows the Tokyo map printed on Toraysee, and you will see how fine it is. This printing capability may add an intellectual pleasure to the physical function.

Another variable is the area of area of skin that can come in direct skin contact with these surfaces. Some of the original work on this issue was done by the New York State Department of Health. Under the New York State method, the activity is evaluated as to exposure potential and the surface area in cm specified for individuals and tasks. Assessments are then made as to the percent of uptake off surfaces. Empirical evidence suggest that 80-90% of the surface PCB contamination can be removed by wiping a surface with a hexane saturated wiping cloth. It is thus seen as a very conservative assessment that the dry skin of the hand would have significantly less uptake efficiency. Variations on this uptake efficiency can significantly vary the outcome. 

Some split fibers impart sharp-angled edges in the surface of fiber, which act as gentle abraders when they are made into wiping cloths in the optical and precision...

Wipes are often made from tissue paper or spun-laced nonwoven fabrics of polypropylene in blend with viscose rayon in the range of 30-70 g/m which may be soaked with an antiseptic finish. One of the most obvious requirements for a wipe cloth is its rapid absorbency, which may be achieved by the addition of a SAP component... 

It is also effective to reduce sub materials used in adhesion processes such as wiping cloths, gloves, masking tapes, removing agents, mixing cups, brushes, and static mixing nozzles. 

The tearing fibers produced according to the processes described can again reach the textile production process as raw materials. This happens, for example, in the field of woolen spinning (outerwear fabrics, carpet yarns), nonwoven production (sound and heat damping materials), and for the production of composites for the automobile industry (hat racks, inside covers). Additional applications are cleaning and wiping cloths made from woven friction yarns or from stitch-bonded nonwovens.
