m k systems danvers mass in this test a dry fabric specimen is placed onto a flat surface that is connected by a liquid bridge to a reservoir of water sitting on a top loading balance as liquid is taken up by the fabric the amount transferred from the reservoir to the fabric is recorded as a loss in weight at the balance the corresponding time interval from test initiation is likewise recorded automatically the uptake rate is obtained from the rate of change of the balance reading typical fabrics absorb liquid most rapidly at the initiation of the test and more slowly as they reach their absorptive limit absorptive capacity the rate data reported herein is the rate of liquid uptake when the fabric has reached 50 of its total capacity rate 50 in g g s total capacity is reported herein as the weight of liquid sorbed by the fabric expressed as a percentage based on the sample weight basis weight oz yd 2 is determined by measuring the mass of a 4 inch by 6 inch fabric sample according to the method described in inda standard test ist 130 1 92 option 1 2 3 and reported as mass per unit area a single expression of two of the most important wiper parameters absorbency and particles which can be removed are described by the use of a particle sorbency quotient psq which quantifies the number of particles introduced into an environment per one liter of water absorbed mathematically equ1 the.
