Position is equipped with horizontal ruler to adjust rubbing surface level；Short side center line installs a fixed pulley, convenient for sliding shoe traction rope and perseverance
Fast pulling force recorder is connected；The surface in drawing work area is that the colorfastness to rubbing of AATCC8 defined tests dedicated 1X1 plain weave cotton
Cloth.Sliding shoe is a square, and specification is 100 × 100 × 15mm, and quadrangle opens up threaded hole to fix pressure zone item, each pressure zone
Position of center line opens up Φ 3mm aperture, draws sliding shoe movement for being connected with traction rope and can to meet ribbon possible
The testing requirement of different directions.Shoe edge is marked with length mark, to facilitate ribbon that can fix by required stretching aperture
On sliding block, to realize the extension test of different opening.
As shown in Fig. 3, ribbon tensionless winkler foundation (0%) along its length is tested respectively, and 20% and 40% is quantitative three times
It stretching, while ribbon is fixed on sliding friction block by static to linear uniform motion, sliding block total weight is 0.355KG,
The tractive force measured in the stroke of 20mm.
When ribbon is continuously increased with stretching aperture, required tractive force constantly reduces.The tractive force from attached drawing 3
The maximum value of curve is for sliding block by static into tractive force required when moving.It can thus be seen that ribbon is in different stretch aperture feelings
Its maximum static friction force is 4.99N, 4.50N, 4.38N respectively under condition, and mean kinetic friction force is 4.60N, 4.20N respectively,
3.98N, thus can calculate coefficient of maximum static friction of the elastic woven tape under different stretch aperture is respectively: 1.43,
1.29,1.26；Mean coefficient of kinetic sliding friction is respectively: 1.32,1.20,1.14.
As shown in Fig. 4, the performance test of broadwise reciprocating friction is carried out to the anisotropic elastic woven tape of a coefficient of friction.It rubs
Cleaning block drive ribbon is along broadwise by static to linear uniform motion.Sliding block total weight is 0.33KG, is measured in the stroke of 20mm
Tractive force.When ribbon is moved back and forth along broadwise, advance significantly different with coefficient of friction when replying.
It can be seen that from attached drawing 4, the maximum static friction force of anti-sliding direction is 3.37N, and mean kinetic friction force is 3.33N；It returns
Compound to maximum static friction force be 2.27N, mean kinetic friction force is 2.1N.It is quiet that anti-sliding direction maximum can be calculated by formula (1)
