Embodiment 1

[0056] Embodiment 1 provides a kind of hydrophobic and antibacterial multifunctional coated cloth, including non-woven fabric and lotus leaf powder hydrophobic and antibacterial coating coated on the non-woven fabric by electrostatic flocking method.

[0057] Wherein, the electrostatic flocking amount of the lotus leaf powder hydrophobic antibacterial coating is 100g / m 2 The thickness of the hydrophobic antibacterial coating of the lotus leaf powder is 1.5mm; the particle size of the lotus leaf powder is 150nm.

[0058] The preparation method of described a kind of hydrophobic antibacterial multifunctional coated cloth, comprises the steps:

[0059] S1. Electrostatic treatment of lotus leaf powder: choose lotus leaf powder of predetermined specifications for electrolytic treatment;

[0060] S2, gluing: heat the hot melt adhesive to melt, and then apply the melted hot melt adhesive on the outer surface of the non-woven fabric to form an adhesive layer; the coating amount of th...

Embodiment 2-5

[0066] Embodiment 2-5 provides a kind of hydrophobic and bacteriostatic multifunctional coated cloth, compared with embodiment 1, the difference is that in the preparation method step S2 of the described hydrophobic and bacteriostatic multifunctional coated cloth, the Except for the above differences, other operations are the same for the coating amount of the above-mentioned hot melt adhesive, and will not be repeated here; the specific experimental conditions, parameters and measurement results are shown in the table below.

[0067]

[0068] It can be seen from the results in the above table that when the coating amount of the hot melt adhesive is less than 200g / m 2 When the flocking density and fastness of the lotus leaf powder and the antibacterial performance of the multi-functional coated cloth are poor, when the coating amount of the hot melt adhesive is greater than 250g / m 2 , the flocking density and fastness of lotus leaf powder, the hydrophobicity and the antibac...

Embodiment 6-9

[0070] Embodiment 6-9 provides a kind of hydrophobic and bacteriostatic multifunctional coated cloth, compared with embodiment 1, the difference is that in the preparation method step S3 of the described hydrophobic and bacteriostatic multifunctional coated cloth, the In addition to the above differences, the other operations are the same as the above-mentioned flocking indoor pole plate spacing, and will not be repeated here; the specific experimental conditions, parameters and measurement results are shown in the table below.

[0071]

[0072]

[0073] Comparing the results of Example 1 and Examples 6 to 9 in the table, it can be seen that with the increase of the distance between the pole plates, the flocking density and fastness of the lotus leaf powder generally show a downward trend, but within the distance between the pole plates less than 15cm, It has little effect on the flocking density and fastness of lotus leaf powder, and when the distance between the plates ...

Abstract

The invention discloses a hydrophobic and bacteriostatic multifunctional coating fabric and a preparation method thereof. Natural lotus leaf powder is fixed on the surface of a non-woven fabric through an electrostatic flocking method to prepare the coating fabric with good hydrophobic and bacteriostatic functions. By the electrostatic flocking method, the lotus leaf powder can uniformly coat thesurface of the non-woven fabric while maintaining the special hydrophobic and bacteriostatic activity; and the advantages of high attachment firmness and flocking density controllability are realized.Meanwhile, the natural lotus leaf powder is used as a mildew-proof bacteriostatic agent to prepare the multifunctional coating fabric; the raw material sources of lotus leaves are wide; the cost is low, so that the production cost of the multifunctional coating fabric is favorably reduced; and the utilization rate of the lotus leaves is improved. The preparation method is simple and fast; the flocking effect is good; the existing equipment can be used for preparation; and the industrialization is easy.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a hydrophobic and antibacterial multifunctional coated cloth and a preparation method thereof. Background technique [0002] Coated cloth is mainly coated with a layer of material with special functions on the basis of cloth, which adds special functions to the cloth. Coated cloth is widely used in tents, clothing, bags, national defense, transportation and many other fields. Coated cloth will inevitably come into contact with a high humidity environment during use or storage. At this time, the waterproof and antibacterial properties of coated cloth are particularly important. [0003] At present, the method of coating waterproof materials on the cloth is often used to achieve waterproofing, and the method of adding antibacterial materials to achieve a better antibacterial effect. However, in the prior art, there are very few coated cloths that simultaneously realize waterproof...
