The structure of the fiber contains the sulfonic acid radical, which has a strong affinity to the cationic dyeing material; the combination ability with dye molecule is enhanced, improving the dye ability of fiber.
Because of the the fourth monomer soft segments, ECDP can be boiled at normal pressure with the cationic dyeing material, while maintaining a high dyeing rate and high dye absorption rate.

This material model uses an isotropic pressure dependent yield surface for the description of homogeneous materials.
The multi-material designed parts are made of at least two different materials.
From the numerical point of view, for FE - modeling of the clinching process an accurate material modeling of both connecting materials is required.

But for many materials, the crack velocity usually can't reach the theoretical maximum velocity.
Researchers put out some explanations to such phenomena perhaps induced by material nonhomogeneity, material anisotropism, crack tip stress singularity, and the bifurcation of stress wave etc, all related to energy dissipation.

The basic idea was to establish a periodical international forum presenting multiscale approaches in fatigue and fracture of materials.
Nearly 180 scientists from 27 countries all over the world presented a variety of fundamental relations between structural and mechanical characteristics of materials.

Therefore, in this work, the investigation would be done for those two materials.
The pin samples were made of tool materials, had a semi-ball with the radii 6mm on one side.
The morphology of the pin of three materials after test was observed by microscope and SEM.
With the increase of velocity, the relative motion of the friction pair trended to intensify, and the wear of these three materials increased.

Tooth bleaching has been routinely used since the late 1870s and several materials and techniques have been presented for this purpose.
They speculated that the cationic polymer treatment prevented the cationic materials from interacting with dentin by electrostatic repulsion.
The null hypotheses were that: there would be no difference to prevent re-staining according to investigated materials.
Materials and methods Tooth selection.
Therefore, the null hypothesis that there would be no difference to prevent re-staining according to investigated materials was rejected.
