Wiper Blade comprising one or more regions of different High and low basis weight and Process for cleaning the same

摘要

Are cleaning sheets having at least two regions, where the regions are distinguished by their weight per unit area or Density superficialllamada basis weight.In particular, the cleaning sheet comprises one or more regions of weight based basealto weighing 30 to 120 g / m2 and a mu00e1sregiones or Low basis weight,Where (S) region (S) of low basis Weight have a basis weight not exceeding 80% of the (S) region (S) of high basis weight.They also Reveal substantial Macroscopic Three dimensionality Cleaning sheets, in addition to multiple areas of different Weight basis.Optionally, theleaves macroscopically three-dimensional Cleaning can understand a Canvas material, which when heated and then cooled.Contracts so as to provide a Macroscopic three-dimensional structure.Macroscopic Three dimensionality is described in terms of the difference in average height and average distance from Peak to Peak.The Road limpiadorapuede is disposable and provide reduction of materials and particles in the air or on Land and can be covered in Articles of manufacture.They also Reveal processes to use the leaves, the benefits of These processes, and articles of manufacture.
