Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
This embodiment will be described in detail with reference to fig. 1. The super-absorbent sanitary non-woven fabric comprises a first nylon fiber layer 1, a super-absorbent fiber layer 2 and a second nylon fiber layer 3 which are sequentially arranged. The first nylon fiber layer 1 and the second nylon fiber layer 3 are both made of nylon spunlace nonwoven fabrics. The first nylon fibre layer 1 comprises a first cross-laid fibre layer 12 and a first parallel-laid fibre layer 11. The second nylon fiber layer 3 comprises a second cross-laid fiber layer 32 and a second parallel-laid fiber layer 31. The first cross-laid fibrous layer 12 and the second parallel-laid fibrous layer 31 are located on both layers of the superabsorbent fibrous layer. The first nylon fiber layer 1 uses antibacterial nylon fibers. The surface density of the first nylon fiber layer 1 is 35-40 grams per square meter, and the surface density of the super absorbent fiber layer 2 is 25-30 grams per square meter; the second nylon fiber layer 3 has an areal density of 35 to 40 grams per square meter.
The first cross lapping fiber layer 12 is formed by carding into a net through a carding machine and then cross lapping through a cross lapping machine, the first parallel lapping fiber layer 11 is formed by directly lapping through the carding machine, and the first nylon fiber layer 1 is reinforced by superposing the first cross lapping fiber layer 12 and the first parallel lapping fiber layer 11 and then carrying out a spunlace reinforcing process. In this embodiment, the first cross-plied fiber layer 12 has a cd strength ratio of 1. 1-1.5: 1, specifically 1.2, with an areal density of 25 grams per square meter; the longitudinal-transverse strength ratio of the first parallel lapping layer 11 is 3-5: 1, specifically 3.5, and an areal density of 15 grams per square meter. The first nylon fiber layer 1 uses antibacterial nylon fiber with fineness of 1.5D and length of 38 mm.
The second cross lapping fiber layer 32 is formed by cross lapping through a cross lapping machine after being carded into a net through a carding machine, the second parallel lapping fiber layer 31 is formed by direct lapping through the carding machine, and the second nylon fiber layer 3 is reinforced through a spunlace reinforcing process after the second cross lapping fiber layer 32 and the second parallel lapping fiber layer 31 are overlapped. In this embodiment, the second cross-plied fiber layer 32 has a cd-to-cd strength ratio of 1.1 to 1.5: 1, specifically 1.5, with an areal density of 30 grams per square meter; the longitudinal and transverse strength ratio of the second parallel lapping layer 31 is 3-5: 1, specifically 4, and an areal density of 10 grams per square meter. The nylon fiber used in the second nylon fiber layer 3 is common nylon fiber, the fineness is 1.2D, and the length is 38 mm.
The fineness of the fiber used by the first nylon fiber layer 1 is larger than that of the fiber used by the second nylon fiber layer, so that the water guide performance of the first nylon fiber layer 1 can be realized, and body fluid can be quickly guided into the super-absorbent fiber layer 2.
The super absorbent fiber layer 2 is made of super absorbent fiber SAF by air-laying, and has an areal density of 25-35 g/m, specifically 30 g/m.
After the first nylon fiber layer 1, the super absorbent fiber layer 2 and the second nylon fiber layer 3 are sequentially overlapped, the first cross lapping fiber layer 12 and the second parallel lapping fiber layer 31 are positioned on two layers of the super absorbent fiber layer. And then the needle is processed by a needle punching process.
