As can be seen from table 1, the difference between example 3 and example 4 is that: the mass ratio between soybean phospholipid and cholesterol in example 3 is 4:1, the mass ratio between soybean phospholipid and cholesterol in example 4 is 5:1, the mildew-proof grade of example 3 is 0, the mildew-proof grade of example 4 is 2, and compared with example 3, the mildew-proof effect of example 4 is reduced, because the content of cholesterol is reduced after the mass ratio of soybean phospholipid is increased, the stability of fluidity of liposome membrane is poor, so that the stability of tea tree essential oil is reduced, the encapsulation efficiency of the encapsulating agent is reduced, the liposome membrane is easy to crack, the tea tree essential oil is easy to volatilize, and the effect of inhibiting and inactivating thalli in a long-acting manner is difficult to achieve, so that the mildew-proof effect of cloth is reduced.
As can be seen from table 1, the only difference between example 3 and example 5 is: the mildew preventive in example 3 contains 9g of an encapsulating agent and 18g of a slow-release auxiliary agent, the mildew preventive in example 5 is not added with the encapsulating agent, the dosage of the slow-release auxiliary agent is 27g, the mildew preventive in example 3 is 0 grade, the mildew preventive in example 5 is 3 grade, and compared with that in example 3, the mildew preventive in example 5 is reduced, because the encapsulating agent is a liposome membrane formed by matching soybean phospholipid with cholesterol, the tea tree essential oil is coated, when the encapsulating agent is not added, only the slow-release auxiliary agent coats the tea tree essential oil, the stability of the tea tree essential oil is weakened due to a single coating effect, the solubility of the tea tree essential oil is reduced, the antibacterial activity of the tea tree essential oil is difficult to be improved, the long-term antibacterial effect is difficult to achieve, and the mildew preventive effect of the cloth is reduced.

The color fastness grade of example 3 is 5, the color fastness grade of example 6 is 4, and the color fastness grade of example 6 is reduced compared with that of example 3, because the content of chitosan is reduced after no slow release auxiliary agent is added, the content of amino in the mildew preventive is reduced, the cationic performance is weakened, the dye uptake is reduced, and the color fastness is reduced after cloth friction.

The example 3 has a 5-level color fastness, the comparative example 1 has a 3-level color fastness, and the comparative example 1 has a reduced color fastness compared with the example 3 because the cationic property and the electrostatic attraction of the dye are reduced after the diethylenetriamine is combined with the epoxy group in the epoxy resin, and the stability of the dye is reduced, so that the color fastness of the cloth is reduced and the color fastness of the cloth is reduced.
As can be seen from table 1, example 3 differs from comparative example 2 only in that: in example 3, the encapsulant was soybean phospholipid and cholesterol, in comparative example 2, the encapsulant was only soybean phospholipid, the mildew-proof grade of example 3 was 0, the mildew-proof grade of comparative example 2 was 2, and the mildew-proof grade was reduced compared with example 3, because after cholesterol is removed, liposome membrane is difficult to form with soybean phospholipid, lipid bilayer arrangement of soybean phospholipid is disordered, fluidity of soybean phospholipid membrane is high, stability is poor, encapsulation efficiency of tea tree essential oil is difficult to be improved, tea tree essential oil is free, volatilization is easy, and lasting antibacterial effect is difficult to be achieved, so that mildew-proof performance of cloth is reduced.
As can be seen from table 1, example 3 differs from comparative example 3 only in that: in the example 3, the color fixing agent is chitosan and hydroxypropyl trimethyl ammonium chloride, the color fixing agent in the comparative example 3 is only chitosan, the color fastness grade of the example 3 is 5, the color fastness grade of the comparative example 3 is 3, and compared with the example 3, the color fastness of the comparative example is reduced, because the chitosan molecule is not cationized by quaternary ammonium salt, the cationic performance of the color fixing agent is difficult to be improved, the bonding capability between the color fixing agent and cloth is poor, the negative charge reducing effect of the cloth is difficult to be improved, and the stabilizing effect of dye is weak; meanwhile, the ionic bond bonding capability of chitosan which is not modified by quaternary ammonium salt ionization and an anionic group in the dye is poor, the water solubility of the dye is difficult to be reduced, and the color fastness is reduced.
As can be seen from table 1, example 3 differs from comparative example 4 only in that: in example 3, the anti-wear agent is epoxy resin and graphene oxide, the anti-wear agent in comparative example 4 is epoxy resin, the color fastness grade of example 3 is 5, the color fastness grade of comparative example 4 is 4, and compared with example 3, the color fastness grade of comparative example 4 is reduced, because the abrasion rate of the epoxy resin is high, the epoxy resin can be quickly failed after being rubbed with an external object, meanwhile, the improvement capability of the bonding surface between the epoxy resin and the fiber is weak, a better interface structure is difficult to form, at the moment, dye components in the cloth are exposed to the outside, the dye is separated from the cloth fiber after abrasion, and the color fastness of the cloth is reduced.
