It is immersed in afterwards in the sulfuric acid solution that concentration is about 1 for 0.3 weight %, pH value；Soaked 264 hours under conditions of being 85 DEG C in temperature
After take out；Then with a large amount of pure water rinsings about 10 minutes and and soak about 2 hours, further take out and dry.(2) abrasive filaments are cut into length
Degree is about 50cm, is then immersed in concentration as in the sulfuric acid solution of 30 weight %, pH value less than 1；In the condition that temperature is 85 DEG C
Lower immersion is taken out after 24 hours；Then with a large amount of pure water rinsings about 10 minutes and soak about 2 hours, further take out and dry.
2. rate of weight loss
A number of abrasive filaments are taken, it is about 35mm to be cut into length, measures its weight m0, then put down by weight
Four parts are divided into, every part of abrasive filaments are fixed on four dops at intervals of 90 ° on same chuck with knob respectively, is ground
Expect in-plane of the axial direction perpendicular to chuck of silk, and it is about 31.75mm that it, which exposes chuck length,；By one it is a diameter of about
8mm copper rod is fixed on above chuck, the axial direction of copper rod parallel to chuck in-plane, and its it is vertical with chuck away from
From for about 24mm；Chuck is rotated with about 14.3Hz rotational frequency so that four tow are ground copper rod on identical point；About 30
Stop the rotation chuck after minute, removes four parts of tow, measures its gross weight m.

The value of the rate of weight loss of the abrasive filaments of example is " disconnected ", that is, abrasive filaments are all broken after being ground, then abandon, also no longer measure
Its relative viscosity, the value of its relative viscosity loss late are recorded as "None".
Table 1
“a" showing that abrasive filaments are dropped after being all broken after being ground, the value of rate of weight loss is recorded as " breaking "；“b" table
It is bright to show that abrasive filaments are dropped after being all broken after being ground, and do not test its relative viscosity loss late.
By the result of table 1, described below is obvious.
