Examples of effects
Table 1 below shows the results of performance analysis of the skin-feel fabrics using examples 1 to 4 of the present invention and the comparative example.
TABLE 1
Compared with the experimental data of the embodiment 1 and the comparative example in the table 1, the modified polyaniline prepared by adding the modified polyaniline of No. 1 and the modified polyaniline of No. 2 into the modified polyurethane coating agent can effectively improve the hand feeling grade and the water absorption rate of the skin-feeling fabric when the skin-feeling fabric is prepared; from the comparison of the experimental data of example 1 and example 2, it can be seen that when No. 1 modified polyaniline is added to the modified polyurethane coating agent, the hand feeling of the prepared skin-feel fabric is poor, and from the comparison of the experimental data of example 1 and example 3, when No. 2 modified polyaniline is added to the modified polyurethane coating agent, the water permeability of the coating is poor, so that the water absorption rate of the skin-feel fabric is seriously reduced.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
