is vertically immersed in a container filled with dip the dip permeability through fiber capillary in two minutes is then measured by tracking the vertical progress of the dyed dip the apparatus includes two ring stands for holding test cords dip container of one inch diameter and one inch depth and control motor 1 8 hp with manual rpm control to feed test yarn through apparatus all test specimens must be conditioned at least 24 hours at atmosphere of 70 u00b0 f and 65 relative humidity as directed in astm d1776 for the test procedure step 1 is to mix three drops of red dye well with dip solution step 2 is to pull the test cord through a sample holder in the order of a first ring stand dip container and a second ring stand to the control motor wind the cord on the pulley of the control motor finally apply 20 gms pretension weight on the cord between the first ring stand and the ruler step 3 is to fill the dip container with the colored dip make sure dip level is at the top edge of the dip container even with the u201c 0 u201d on the ruler step 4 is to turn on the motor and feed a section of yarn through the dip stop the motor and start the test step 5 is to allow dip to wick two minutes on the specimen measure and report position of colored dip as it climbs the sample repeat steps 4 and 5 for nine times per fiber calculate average and standard deviation of ten wicking reading comparative a was an industrial yarn.
