Abstract

The invention discloses a non-woven fabric with a biological regulation function and a preparation method thereof. The non-woven fabric disclosed by the invention is processed by using a finishing agent prepared by using a functional combined solution, the functional combined solution comprises 25-60 wt% of oligosaccharides and 5-30 wt% of probiotic bacteria metabolites, and the functional combined solution accounts for 7-20% of the weight of the finishing agent. The preparation method comprises the following steps: 1) the preparation of the functional combined solution, namely, taking all components in proportion, adding oligosaccharides into a moderate amount of water, and stirring the obtained mixture; after the oligosaccharides are dissolved, adding probiotic bacteria metabolites into the obtained object, and stirring the obtained mixture; and adding the other components of the functional combined solution and the balance of water, and after the obtained object is mixed, adjusting the pH value of the obtained mixture to be 5-6 by using a pH regulator; 2) taking the functional combined solution and the other finishing agent components in proportion so as to prepare a finishing agent; and 3) applying the finishing agent containing the functional combined solution to the non-woven fabric, removing the redundant finishing agent, and then drying or air-drying the obtained product. The non-woven fabric disclosed by the invention has a biological regulation function, and can enhance the microbial barrier capabilities of skins and genital tracts, restrain the proliferation of pathogenic bacteria, and protect the human health.

Description

technical field [0001] The invention relates to a non-woven fabric and a preparation method thereof, in particular to a non-woven fabric with a growth-promoting effect on beneficial bacteria on the human body surface including skin and reproductive tract, and a preparation method thereof. Background technique [0002] The skin on the surface of the human body and the lower reproductive tract have their own specific micro-ecological structures. The microorganisms in each structure are closely combined with skin or mucosal cells to form a layer of microbial barriers, which play a role of biological space-occupying protection. Produce short-chain fatty acids, reduce the pH and Eh in the habitat, prevent the adhesion and colonization of foreign bacteria, and compete with foreign bacteria for nutrients, thereby effectively inhibiting the invasion, growth and reproduction of foreign bacteria. [0003] Human skin microecology is composed of skin, skin biotic environment and abiotic...
