WET STRENGTH

wet strength paper 湿强纸

natsterkte

(mec) rezistenţa la rupere în stare umedă
  

Papers to which this term applies retain an appreciable percentage of their mechanical strength after soaking in water, and are made by the addition of a resin to the stock during paper manufacture. This resin cements the fibres together and the bond tends to improve with age. The advantages of printing maps on, or making certain wrappings from, wet strength paper are obvious.
