[0015] Patent application 201510496205.8 discloses a water-absorbing composite silk fabric, in which the middle water-absorbing layer fabric is one or more of viscose fiber fabric layers, ramie fiber fabric layers, jute fiber fabric layers and wool fiber fabric layers, and its outer surface Wrapping a layer of silk fabric layer does not systematically improve the raw materials. It adopts the method of superimposing fiber materials to form a space layer, and then forms a water absorption effect, and the raw materials headed by silk are expensive. In this era of energy saving and emission reduction Next, this way is a bit inadvisable

Embodiment 1

[0057] This embodiment discloses a multi-layer protective diaper, which is composed of an antibacterial and deodorant fabric layer, a sweat-absorbing and moisture-conducting fabric layer, a water-absorbing non-woven fabric layer, and a surface layer sequentially from the inside to the outside. In some diapers, a diversion layer is compounded between the sweat-absorbing and moisture-conducting fabric layer and the antibacterial and deodorant fabric layer.

Embodiment 2

[0059] This embodiment discloses a preparation method of an antibacterial and deodorant fabric, comprising the following steps:

[0060] (1) Select bamboo fiber, grind it into fiber fragments with a length of 2 mm, cook the fiber fragments in alkaline cooking liquid at 110°C for 2 hours, and then filter to obtain bamboo fiber pulp.

[0061] (2) Add dihydroxypropyl chitosan to the bamboo fiber pulp in step (1), and mix it at 40°C for 2 hours in NaOH, thiourea, urea, and water solvent system to obtain dihydroxypropyl chitosan Chitosan / bamboo fiber pulp hybrid system. Wherein, the mass ratio of dihydroxypropyl chitosan to bamboo fiber pulp is 1:40. The mass ratio of the total amount of dihydroxypropyl chitosan and bamboo fiber pulp to the NaOH, thiourea, urea, and water solvent system is 1:5.

[0062] (3) Add nano-titanium dioxide, nano-molybdenum dioxide, and aloe extract to the dihydroxypropyl chitosan / bamboo fiber pulp mixing system in step (2), and mix for 30 minutes to obt...

Embodiment 3

[0067] This embodiment discloses a preparation method of an antibacterial and deodorant fabric, comprising the following steps:

[0068] (1) Bamboo fibers were selected, ground into fiber fragments with a length of 5 mm, and the fiber fragments were cooked in an alkaline cooking solution at 130° C. for 1 hour, and then filtered to obtain bamboo fiber pulp.

[0069] (2) Add dihydroxypropyl chitosan to the bamboo fiber pulp in step (1), and mix it at 60°C for 1 hour in NaOH, thiourea, urea, and water solvent system to obtain dihydroxypropyl chitosan Chitosan / bamboo fiber pulp hybrid system. Wherein, the mass ratio of dihydroxypropyl chitosan to bamboo fiber pulp is 1:10. The mass ratio of the total amount of dihydroxypropyl chitosan and bamboo fiber pulp to the NaOH, thiourea, urea, and water solvent system is 1:8.

[0070] (3) Add nano-titanium dioxide, nano-molybdenum dioxide, aloe extract, and lemongrass extract to the dihydroxypropyl chitosan / bamboo fiber slurry mixing syste...

Abstract

The invention discloses a multi-layer protective diaper, which sequentially includes an antibacterial and deodorant fabric layer, a sweat-absorbing and moisture-conducting fabric layer, a water-absorbing non-woven fabric layer, and a surface layer from the inside to the outside. The invention also discloses a method for preparing the multi-layer protective diaper . The invention has the advantages of good antibacterial effect, strong deodorizing ability, moisture absorption and perspiration.

Description

technical field [0001] The invention relates to the technical field of diapers, in particular to the technical field of multi-layer protective diapers and a method for preparing the diapers. Background technique [0002] With the development of society, people pay more and more attention to the issue of baby care. From the simple diapers to the current diapers, diapers have been developed for several generations. The user groups of diapers mainly include babies and adults. It usually includes a surface layer, an absorbent core layer, a water-absorbing paper layer, and a skin-friendly layer from outside to inside. Some diapers are also equipped with a diversion layer between the water-absorbing paper layer and the skin-friendly layer. , to improve the precision of urine flowing into the absorbent core layer, and prevent the disordered flow of urine. [0003] The skin-friendly layer is often made of hot-air or hot-rolled non-woven materials, which are required to be soft and...
