Problems solved by technology

[0002] At present, adult diapers on the market mainly include structures such as non-water-permeable outer layer, absorbent body, water-permeable inner layer, left and right stickers, leak-proof flanks and leg bending elastic bands, among which the left and right stickers are made of PP material. When used, the number of repeated bonding is small, the adhesive force is not enough, especially the air permeability is poor, the comfort is low, and the leak-proof performance is poor.

Embodiment 1

[0042] Such as Figure 1 to Figure 5 As shown, a kind of adult paper diapers, including trouser body and anti-leakage flanks on the trouser body, front waist sticker and back waist sticker, the front waist sticker is fixed on the outer surface of the trouser body, and the back waist sticker is divided into left back waist sticker and back waist sticker. The right back waist sticker, the left back waist sticker and the right back waist sticker are respectively fixed on the left and right sides of the rear part of the trouser body; the leak-proof flanks are arranged on the left and right sides of the middle part of the trouser body in the length direction; the trouser body has a layered structure, The layered structure comprises an adsorption layer, an absorption layer, a first expansion layer, a second expansion layer and an anti-leakage layer from top to bottom. The adsorption layer is woven by modified nano-polyvinyl alcohol electrostatic wire, the weaving aperture is 300nm, ...

Embodiment 2

[0044] Such as image 3 As shown, the modified nano-polyvinyl alcohol electrostatic wire is prepared by the following steps,

[0045] Step 1: Weigh 1 part of cellulose, take an appropriate amount of deionized water and stir to dissolve, add tetramethylpiperidine oxide to the solution according to the molar ratio of cellulose: tetramethylpiperidine oxide 1:0.05, according to the cellulose: Add sodium hypochlorite to the solution at a molar ratio of sodium hypochlorite of 1:1 to adjust the pH of the system to 10.3, and stir at room temperature for 24 hours;

[0046]Step 2: disperse the system into a gel form through a homogenizer, undergo ultrasonic treatment for 10 minutes, filter and then freeze-dry to obtain nanocellulose;

[0047] Step 3: Weigh 1 part of polyvinyl alcohol, take an appropriate amount of deionized water, heat to 80°C and maintain a constant temperature, stir for 2 hours until completely dissolved;

[0048] Step 4: Cool naturally to room temperature, dilute t...

Embodiment 3

[0051] Such as Figure 4 to Figure 5 As shown, the flexible absorbent fiber was prepared by the following steps,

[0052] Step 1: Weigh 1 part of xanthan gum, add an appropriate amount of deionized water, stir and dissolve, add acrylic acid with a neutralization degree of 85% to the xanthan gum solution according to the volume ratio of xanthan gum solution:acrylic acid solution=1:2.5 Solution, after stirring, add acrylamide solution to the mixed solution according to the volume ratio of acrylic acid solution: acrylamide solution = 1:1;

[0053] Step 2: Heat the mixed solution to 70°C, mix the solution according to the volume ratio: crosslinking agent = 1:0.05, add the crosslinking agent N,N-methylenebisacrylamide, and keep stirring at a constant temperature of 70°C for 1 hour;

[0054] Step 3: Heating to 85°C, adding the initiator potassium persulfate solution into the solution according to the volume ratio of crosslinking agent:initiator = 1:1, and continuing to stir at a co...

Abstract

The invention discloses an adult diaper and belongs to the field of daily necessities. The adult diaper comprises a diaper body, leakage-preventing lateral wings on the diaper body, a front waist sticker and a rear waist sticker. The front waist sticker is fixed on the outer side of the diaper body. The rear waist sticker includes a left rear waist sticker and a right rear waist sticker which are respectively fixed on the left and right sides of the rear portion of the diaper body. The leakage-preventing lateral wings are arranged on the left and right sides of the middle portion in the length direction of the diaper body. The diaper body is of a layered structure. The layered structure sequentially comprises an absorption layer, an absorbing layer, a first expansion layer, a second expansion layer and a leakage-preventing layer from top to bottom. The adult diaper is good in breathability, convenient to wear and take off, good in water absorption performance and capable of preventing lateral leakage.

Description

technical field [0001] The invention relates to a daily necessities, in particular to an adult diaper. Background technique [0002] At present, adult diapers on the market mainly include structures such as non-water-permeable outer layer, absorbent body, water-permeable inner layer, left and right stickers, leak-proof flanks and leg bending elastic bands, among which the left and right stickers are made of PP material. When used, the number of repeated bonding is small, the adhesive force is not enough, especially the air permeability is poor, the use comfort is low, and the leak-proof performance is poor. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems and provide adult diapers with good air permeability, easy on and off, strong water absorption and side leakage prevention. [0004] The technical scheme that the present invention adopts is as follows: [0005] An adult diaper of the present invention comp...
