Description

Bamboo fiber sanitary towel with fast infiltration

Technical Field

The utility model belongs to the technical field of health supplies, concretely relates to bamboo fiber sanitary towel that seeps down fast.

Background

The bamboo fiber fabric is a novel fabric which is prepared by weaving bamboo fibers made of bamboo as a raw material through a special process and has the following components: soft and soft, antibacterial, moisture-absorbing and breathable, green and environment-friendly, uvioresistant, natural and health-care, comfortable and beautiful and the like.

The fiber is a mixture of a crystalline state and an amorphous state, and in a crystalline region of the fiber, due to the fact that macromolecules are arranged neatly and compactly, gaps and holes are few, and bonding forces of groups close to each other among molecules are mutually saturated, the fiber is difficult to absorb moisture, high in strength and small in deformation. In the amorphous crystallization area, the arrangement of macromolecules is disordered, the stacking is loose, gaps and holes are more, and the density is lower. Some macromolecules have larger group distance on the surface, smaller connection force, less complete saturation, easy moisture absorption and dyeing, lower strength and larger deformation. In one fiber, a crystallization area and a non-crystallization area exist at the same time, the drafting distribution is adjusted in the spinning forming process (namely the speeds of all the drawing rollers are different), so that cellulose macromolecules are rearranged, fiber molecules are rearranged through secondary drawing, and the molecules are set to have a drawing value, so that the molecular orientation degree is improved, the shrinkage rate is reduced, and the water absorption capacity is reduced. The molecules are arranged orderly, and the gaps among the molecules are reduced.

The sanitary towel surface course on the market at present adopts the non-woven fabrics preparation mostly, exists the problem that oozes slowly, absorption effect is poor, and the surface course material that the material is not good a bit leads to the sanitary towel in the use surface not dry and comfortable enough. While the female menstrual period can cause gynecological diseases such as pruritus, burning, red swelling, red rash and the like if the selected sanitary towel is not suitable.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In addition, the technical solutions between the embodiments of the present invention can be combined with each other, but it is necessary to be able to be realized by a person having ordinary skill in the art as a basis, and when the technical solutions are contradictory or cannot be realized, the combination of such technical solutions should be considered to be absent, and is not within the protection scope of the present invention.

Referring to fig. 1 to 2, a bamboo fiber sanitary napkin with fast infiltration comprises a bamboo fiber cloth surface layer 1, a chip layer 2, a water absorption layer 3 and a breathable bottom film 4, wherein the chip layer 2 and the water absorption layer 3 are arranged in a hot-pressing sealing cavity formed by the bamboo fiber surface layer 1 and the breathable bottom film 4, the bamboo fiber surface layer 1 is nascent bamboo fiber subjected to secondary stretching, the water absorption layer 3 comprises a hydrophilic layer 31, a honeycomb layer 32 and a water locking layer 33, and the honeycomb layer contains high-molecular water absorption particles 34.

The bamboo fiber surface layer is the primary bamboo fiber subjected to secondary drawing, and the secondary drawing is performed after the fiber is formed, so that the fiber molecular orientation degree is improved, the shrinkage rate is reduced, and the water absorption capacity is reduced. After the fibers are stretched for the second time, the molecules are arranged orderly, and gaps among the molecules are reduced, so that when menstrual blood reaches the surface layer, the menstrual blood can rapidly infiltrate down to the middle water locking layer, and the dryness and the smoothness of the surface layer are greatly improved by rapid diffusion of the menstrual blood in the water locking layer. In addition, the knitted bamboo fiber fabric surface layer is more comfortable, breathable and softer than common cotton and dust-free paper surface layers.

Further, the hydrophilic layer 31 is a dust-free paper surface layer; the honeycomb layer 32 is an expanded cotton with a honeycomb structure; the water locking layer 33 is dust-free paper with the thickness of 0.8-1.2 mm. The high-molecular water-absorbing particles 34 are arranged in the honeycomb structure of the expanded cotton, so that the high-molecular water-absorbing particles are uniformly arranged, and the absorption of menstrual blood is promoted. The macromolecular water-absorbing particles are typical functional macromolecular materials, can absorb hundreds of times, even thousands of times of water of the self weight, and have strong water-retaining capacity; the expanded cotton and the dust-free paper are both made of materials with high water absorption, so that menstrual blood can flow through the water absorption layer and be quickly absorbed, and the surface layer of the sanitary towel is kept dry and comfortable.

Further, the chip layer 2 comprises non-woven fabrics soaked by taxol and tea polyphenol from top to bottom; the chip layer is provided with inverted cone-shaped lower seepage holes 21. The arrangement of the non-woven fabrics soaked by the taxol and the tea polyphenol improves the bacteriostatic effect of the sanitary towel. The chip layer is provided with the inverted cone-shaped infiltration holes, so that menstrual blood can be infiltrated rapidly.

Referring to fig. 3, further, elastic strips 5 arranged transversely are arranged between the water-absorbing layer 3 and the breathable bottom film 4. The elastic strip 5 can prevent the sanitary towel from deforming during the use process to cause the problem of side leakage.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
