Referring to table 2, in combination with example 1 and comparative examples 1 and 2, it can be seen that when no fatty alcohol-polyoxyethylene ether and n-butanol are added to the slurry, the permeability of the slurry is significantly reduced; because the fatty alcohol-polyoxyethylene ether has hydrophilic and oleophilic groups, the fatty alcohol-polyoxyethylene ether can be directionally arranged on the surface of the slurry, so that the surface tension of the fabric can be reduced, and the penetration of the emulsified corn starch on the fabric is facilitated; and meanwhile, the n-butanol can improve the hydrophilic-lipophilic balance of the fatty alcohol-polyoxyethylene ether, further improve the osmotic action of the fatty alcohol-polyoxyethylene ether, and the n-butanol and the fatty alcohol-polyoxyethylene ether have a synergistic effect.
Referring to table 2, in combination with examples 1 to 3, it can be seen that the permeability of the slurry is increased as the amount of the emulsified corn starch added to the slurry is increased, but when the content of the emulsified corn starch is too high, the slurry is decreased in permeability because the amount of the emulsified corn starch attached to the inside and outside of the fiber is saturated and the penetration of the emulsifying corn starch by the penetrant and the co-surfactant is weakened.
Referring to table 2, in combination with examples 2, 4 and 5, it can be seen that, as the content of the fatty alcohol-polyoxyethylene ether in the slurry increases, the penetration effect of the penetrating agent on the emulsified corn starch increases, so that the inside and outside adhesiveness of the emulsified corn starch on the fabric is higher, and the permeability of the slurry is improved.
Referring to table 2, in combination with examples 4, 6 and 7, it can be seen that, as the content of the co-surfactant n-butanol in the slurry is continuously increased, the n-butanol enhances the improvement of the surface activity and the hydrophilic-lipophilic balance of the fatty alcohol-polyoxyethylene ether, so that the penetration of the fatty alcohol-polyoxyethylene ether to the emulsified corn starch is further improved, and the permeability of the slurry is improved.
Referring to table 2, in combination with examples 6 and 8 and comparative example 3, it can be seen that the addition of a proper amount of silicone softener to the slurry has a great effect of improving the softness of the produced fleece; the organic silicon softening agent can form reverse adsorption of the hydrophobic groups outwards on the limiting surface, and reduces the dynamic and dynamic friction factors of the fibers, so that the fabric obtains smooth and soft hand feeling.
Referring to table 2, in combination with examples 6 and 9 and comparative example 4, it can be seen that the down-filled cloth produced by adding a proper amount of graphene oxide gel to the slurry has a good antistatic effect; the reason is that the graphite oxide gel can form nanometer gel particles on the inner surface and the outer surface of the fabric after being added into the slurry, and the moisture absorption effect of the binding water and the epoxy groups in the gel particles can reduce the charges generated on the surface of the fabric, so that the antistatic effect of the produced polyester-nylon double-layer suede cloth is improved.
Referring to table 2, in combination with examples 9 and 10, it can be seen that, by properly changing the addition amount of the deionized water in the slurry, the prepared slurry still has good permeability, and meanwhile, the polyester-nylon double-layer suede produced by the slurry still has good antibacterial property and softness.
Referring to table 2, in combination with examples 1, 11 and 12, it can be seen that the mass ratio of corn starch to tween in the preparation of emulsifying corn starch in slurry has an influence on the permeability of the prepared slurry; particularly, when the mass ratio of the corn starch to the Tween is 3:1, the prepared emulsified corn starch has the best emulsibility, so that the permeability of the slurry is optimal.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
