Embodiment 1

[0026] The preparation method of the breathable and urine-penetration-resistant nonwoven material of this embodiment includes the preparation of the base fabric and the urine-penetration-resistant finishing, as follows:

[0027] (1) Preparation of base fabric: spunbond, meltblown, meltblown, spunbond, hot rolling, winding.

[0028] Spunbond: extrude polypropylene slices through a screw extruder, filter, metering pump, spin with a spinning die, air draft, and form a web, with a fineness of about 20 microns and a weight of 6.5g / m 2 .

[0029] Meltblown: Extrude polypropylene chips through a screw extruder, filter, metering pump, spin with a spinning die, draw with hot air, cool, and form a web with a fineness of about 20 microns and a weight of 3.5g / m 2 .

[0030] Meltblown: Extrude polypropylene chips through a screw extruder, filter, metering pump, spin with a spinning die, draw with hot air, cool, and form a web with a fineness of about 3 microns and a weight of 3.5g / m 2 ....

Embodiment 2

[0055] The preparation method of the breathable anti-urine nonwoven material of this embodiment is similar to that of Example 1, the difference is that the composition of the anti-urine finishing solution of this embodiment and its percentage in the anti-urine finishing solution are as follows:

[0056]

[0057]

[0058] Product performance test:

[0059]The breathable urine-resistant nonwoven material prepared in the above-mentioned Example 2 was tested for urine resistance and air permeability.

[0060] (1) Anti-urine performance test:

[0061] Test procedure: use artificial urine, the sample size is 50mm×50mm, test at least 3 thin breathable anti-urine nonwoven materials, use a cylinder with a height of 80mm and a diameter of 38mm to fill the artificial urine, place the breathable anti-urine nonwoven material Bottom test impervious time.

[0062] Test result: no penetration for 30 hours.

[0063] (2) Air permeability test:

[0064] Test steps: use a test area of ​...

Embodiment 3

[0070] The preparation method of the breathable anti-urine nonwoven material of this embodiment is similar to that of Example 1, the difference is that the composition of the anti-urine finishing solution of this embodiment and its percentage in the anti-urine finishing solution are as follows:

[0071]

[0072] Product performance test:

[0073] The breathable urine-resistant nonwoven material prepared in the above-mentioned Example 3 was tested for urine resistance and air permeability.

[0074] (1) Anti-urine performance test:

[0075] Test procedure: use artificial urine, the sample size is 50mm×50mm, test at least 3 thin breathable anti-urine nonwoven materials, use a cylinder with a height of 80mm and a diameter of 38mm to fill the artificial urine, place the breathable anti-urine nonwoven material Bottom test impervious time.

[0076] Test result: no penetration for 30 hours.

[0077] (2) Air permeability test:

[0078] Test steps: use a test area of ​​20cm 2 , ...

Abstract

The invention relates to urine-permeating-resistant finishing liquor for a non-woven material. The urine-permeating-resistant finishing liquor is prepared from the components in percentage by mass: 3 to 9 percent of straight-chain paraffin of C16 to C34, 2 to 5 percent of perfluorooctyl sulfonate, 0.1 to 0.6 percent of penetrating agent and 85.4 to 94.9 percent of water. The thin-type breathable non-woven material is subjected to urine-permeating-resistant finishing through the urine-permeating-resistant finishing liquor; the thin-type breathable urine-permeating-resistant non-woven material can prevent urine with the height being 80mm from permeating for 8 hours or more, has favorable durable urine-permeating-resistant performance, air permeability and water vapor permeability and excellent physical performance, and meets the requirements of baby diaper materials and medical protection materials. The non-woven material is used as a bottom layer material of a baby diaper, so that sweat can be effectively excreted, and a stuffy feeling and discomfortableness of a baby or a user are eliminated.

Description

technical field [0001] The invention belongs to the field of nonwoven materials, and in particular relates to a urine-resistant finishing solution for nonwoven materials, a breathable and urine-resistant nonwoven material and a preparation method thereof. Background technique [0002] Now, diapers have become a daily sanitary product for babies, and the frequency of use is very high, even some incontinent adults and the elderly are also using them, which makes our requirements for diapers also increase. When preparing diapers, the bottom layer generally uses PE film to prevent urine leakage. This PE film has poor air permeability, which will seriously affect the comfort and health of babies and users, resulting in red buttocks. [0003] Thin, breathable and anti-penetration non-woven material can improve the air permeability inside the diaper, it is soft and comfortable and does not irritate the skin, it can allow the steam generated by the human body to flow outside the dia...
