Experiment one (moisture permeability)
The samples of examples 1 to 3 and comparative examples 1 to 2 were used as experimental samples, 5ml of water was poured on the samples, and the time taken for the liquid to penetrate the samples was measured by an electrometric method and recorded.
Experiment two (antistatic property)
The examples 1-3 and the comparative examples 1-2 are used as experimental samples, and the first part of the evaluation of the electrostatic property of the textile is as follows according to GB/T12703.1-2008: static voltage half-life ", and data are recorded.
Experimental data
Moisture permeability(s) Half-life(s)
Example 1 0.92 0.79
Example 2 0.57 0.36
Example 3 0.73 0.55
Comparative example 1 1.48 0.40
Comparative example 2 0.64 2.30
Data analysis
As can be seen from the data, examples 1 to 3 are the best in moisture permeability and antistatic property, and among them, example 2 is the best in performance;
compared with example 2, in comparative example 1, the water-absorbing layer fiber web obtained by carding carboxymethylated cotton fibers is lacked, and the water-absorbing performance of the cotton fibers of the inner layer fiber web is limited, so the moisture permeability of comparative example 1 is poor;
compared with example 2, in comparative example 2, the spunlace nonwoven fabric is poor in conductivity and antistatic ability due to the lack of the antistatic layer fiber mesh and the lack of polyaniline and graphene;
in conclusion, the spunlace nonwoven fabric prepared by the invention has good moisture permeability, antistatic performance and flame retardant performance, and has good practicability and industrial production value.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
