Problems solved by technology

Hydrophilic non-woven fabrics and perforated non-woven fabrics generally use hydrophilic fibers as the raw material of non-woven fabrics. Hydrophilic fibers are conducive to rapid wetting and penetration of body fluids when they reach the surface of absorbent products, but due to the high surface energy of the fibers , it is easy to make the body fluid adsorb around the fiber, so that the body fluid remains between the fibers, and at the same time, the capillary phenomenon of the fiber can also make the body fluid after penetration return to the surface of the non-woven fabric and the perforated non-woven fabric, making the user Moist, sticky skin, non-dry feel upon application
In particular, when this hydrophilic non-woven fabric is applied to the surface layer of baby diapers, it is easy to cause allergic phenomena such as redness of the baby's skin and eczema due to its poor dryness.

Embodiment 1

[0027] Such as figure 1 , 2 As shown, a three-dimensional non-woven fabric 1, its surface includes several convex parts 11 and several concave parts 12 in contact with the skin, the convex parts 11 and concave parts 12 are spaced apart from each other, and the convex parts 11 occupy the nonwoven 70% of the total area of ​​the cloth, the height difference between the top end of the convex portion 11 and the bottom end of the concave portion 12 is 0.1 mm.

[0028] The contact angle of the area of ​​each convex portion 1160% with water is greater than 70°, and the area of ​​each concave portion 1290% is less than 70°. The tops 111 of the plurality of protruding portions 11 are all flat; the bottoms 121 of the plurality of concave portions 12 are all flat.

[0029] Its realization is that the common non-woven fabric is passed through a pair of interlocking convex rollers and smooth rollers to form only the upper surface with raised parts, so that the tops of the raised parts 11 ...

[0031] Such as image 3 , 4 As shown, a three-dimensional non-woven fabric 1, its surface includes several convex parts 11 and several concave parts 12 in contact with the skin, the convex parts 11 and concave parts 12 are spaced apart from each other, and the convex parts 11 occupy the nonwoven 30% of the total area of ​​the cloth, the height difference between the top end of the convex portion 11 and the bottom end of the concave portion 12 is 0.7mm.

[0032] The contact angle between the area of ​​each convex portion 1125% and water is greater than 70°, and the area of ​​each concave portion 1290% has a contact angle with water less than 70°; the convex portions 11 are strip-shaped protrusions parallel to each other , the concave portions 12 are strip-shaped concaves parallel to each other; the tops 111 of the plurality of convex portions 11 are arc-shaped; the bottoms 121 of the plurality of concave portions 12 are all flat.

[0033] Its realization method is as follows:...

Embodiment 3

[0035] Such as Figure 5 , 6 As shown, a three-dimensional non-woven fabric 1, its surface includes several convex parts 11 and several concave parts 12 in contact with the skin, the convex parts 11 and concave parts 12 are spaced apart from each other, and the convex parts 11 occupy the nonwoven 30% of the total area of ​​the cloth, the height difference between the top end of the convex portion 11 and the bottom end of the concave portion 12 is 1.6 mm.

[0036] The contact angle between the area of ​​each convex portion 1180% and water is greater than 70°, and the area of ​​each concave portion 1280% has a contact angle with water less than 70°; the convex portion 11 is a dot-like protrusion; the The tops 111 of the plurality of protruding portions 11 are arc-shaped; the bottoms 121 of the plurality of concave portions 12 are all flat.

[0037] Its realization is as follows: the ordinary non-woven fabric passes through a pair of interlocking concave rollers and smooth roll...

Abstract

The invention discloses three-dimensional non-woven fabric. The surface of the three-dimensional non-woven fabric comprises a plurality of convex parts and a plurality of concave parts. The convex parts and the concave parts are arranged at intervals and are made of the same material. The contact angle of 20% to 100% area of each convex part and water is larger than 70 degrees, and the contact angle of 20% to 100% area of each concave part and the water is smaller than 70 degrees. The three-dimensional non-woven fabric has the advantages of being dry and comfortable.

Description

technical field [0001] The invention belongs to the field of absorbent textiles, and in particular relates to a three-dimensional nonwoven fabric. Background technique [0002] At present, people widely use hydrophilic non-woven fabrics and perforated non-woven fabrics as the surface layer of disposable sanitary absorbent products such as medical mattresses, sanitary napkins, panty liners and diapers, in order to achieve comfort and rapid penetration. Hydrophilic non-woven fabrics and perforated non-woven fabrics generally use hydrophilic fibers as the raw material of non-woven fabrics. Hydrophilic fibers are conducive to rapid wetting and penetration of body fluids when they reach the surface of absorbent products, but due to the high surface energy of the fibers , it is easy to make the body fluid adsorb around the fiber, so that the body fluid remains between the fibers, and at the same time, the capillary phenomenon of the fiber can also make the body fluid after penetra...
