Test examples

(1) Test of antibacterial and thermal insulation properties

The antibacterial properties and the heat insulation properties of the aloe fiber-containing antibacterial skin-moistening fabrics prepared in examples 1 to 5 and comparative examples 1 to 4 were tested, and specific test results are shown in table 1:

the detection of each index in table 1 is based on the following criteria: the antibacterial rate is evaluated by GB/T20944.3-2008 section 3 of antibacterial Properties of textiles: the method of vibration.

According to the test results of Table 1, it can be seen that the antibacterial skin-moistening fabric containing aloe fibers prepared by the invention has excellent antibacterial property and good heat preservation property, and has wide application prospects in the field of inner jackets.

In the invention, the surface of the aminated ferroferric oxide is subjected to grafting reaction with the polyethyleneimine in a covalent bonding mode, and then the polyethyleneimine is modified by using haloalkane, so that the high molecular quaternary ammonium salt with an antibacterial function is formed on the surface of the ferroferric oxide, and the antibacterial additive is prepared. The macromolecular quaternary ammonium salt with antibacterial function and the amino ferroferric oxide are connected by covalent bonds and are not easy to fall off, so that the prepared antibacterial additive has high antibacterial activity, high safety performance and long-acting antibacterial capability. The antibacterial nylon fiber obtained by blending and spinning the antibacterial additive and the polyamide has high-efficiency antibacterial property and long-acting antibacterial capability.

The antibacterial additive is not added into the raw material nylon yarn of the functional layer in the comparative example 1, only aloe fiber yarn and aloe/honeysuckle extract in the fabric play an antibacterial role, and the antibacterial skin-moistening fabric prepared by the method has the antibacterial role on escherichia coli and staphylococcus aureus, but is not sensitive to antibacterial components of aloe extract as candida albicans belongs to fungi, and the honeysuckle extract has stronger inhibition on candida albicans, but lacks the antibacterial additive in the fabric, and the inhibition effect is still not as good as that of the examples, so that the comprehensive antibacterial effect is not as good as that of the examples; the functional layer in comparative example 2 was not surface treated with the composite finishing agent, and the aloe fiber yarn was replaced with pure cotton yarn fabric as weft yarn, and the produced fabric lacked the antibacterial effect of aloe/honeysuckle extract, so the overall antibacterial effect was inferior to that of the examples; the composite finishing agent used in the functional layer in comparative example 3 does not contain honeysuckle extract, and since candida albicans belongs to fungi and is insensitive to antibacterial components of aloe fiber and aloe extract, the antibacterial additive has stronger inhibition effect on candida albicans, but the inhibition effect is still not as good as that of the examples, so the comprehensive antibacterial effect is not as good as that of the examples; the inner layer in comparative example 4 was not surface treated with the phase change finish and did not have thermal insulation properties.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
